Re: Wildlife Assessment at Laurel Meadow Subdivision
This memo documents the presence or absence of wildlife resources and Endangered Species Act (ESA) federally listed threatened and endangered species on an approximately 40.83-acre that is located south of The Lakes at Valley West and north and east of Norton Ranch. Directly to the east of the property lies a significant linear parkland including a perpetual wetland easement encompassing Baxter Creek and creates the extension of Bronken Park to the north. A suite of maps is attached to this memo for reference. A summary of our data sources is provided at the end of this memo.
General Habitat
In addition to this desktop analysis, A Morrison-Maierle environmental scientist conducted site visits on August 9 and 10, 2025, to assess habitat conditions. A photo log from the field investigation is attached and the results of our investigation are presented below.
Field observations confirmed suitable habitat for generalist species adapted to human disturbance.
The following species were observed on the subject property:
American robin (Turdus migratorius)
Bedding signs of white-tailed deer (Odocoileus virginianus)
Chipmunk (Neotamias spp.)
Raccoon (Procyon lotor)
Red fox (Vulpes vulpes)
Red-winged blackbird (Agelaius phoeniceus)
Small rodents
Striped skunk (Mephitis Mephitis)
Yellow warbler (Setophaga petechia)
The property is bounded on all sides by residential properties or residential development. This surrounding land use limits connectivity to larger, undisturbed habitat areas and reduces the likelihood of use by wide-ranging or disturbance-sensitive species. Habitat within the property primarily supports generalist species adapted to urban and suburban environments, with limited potential for species requiring extensive, contiguous habitat.
2 | Page
None of the species identified on the U.S. Fish and Wildlife Information for Planning and Consulting (IPaC) report, which is discussed in the following section, were observed within or near the property during the assessment.
The subject property is within the Cultivated Crops and Rocky Mountain Lower Montante Foothill, and Valley Grassland land cover/use areas (MNHP 2025).
Threatened and Endangered Species
There is no critical habitat for any ESA threatened or endangered (T&E) species at the investigation area (USFWS 2023). Furthermore, the investigation area does not contain typical habitat for any threatened or endangered species. While it is possible for the monarch butterfly to migrate through the investigation area, the lack of milkweed plant communities and other useful forbs make it an unlikely stop for this Candidate species.
Table 1
Species ESA Status Present? Critical Habitat?
Canada Lynx (Lynx canadensis) Threatened Has potential to be present, not typical habitat No
Grizzly Bear (Ursus arctos horribilis) Threatened Has potential to be present, not typical habitat No
North American Wolverine (Gulo gulo luscus) Threatened Has potential to be present, not typical habitat No
Monarch Butterfly (Danaus plexippus) Proposed Threatened Has potential to be present No
Suckley’s Cuckoo Bumble Bee (Bombus suckleyi) Proposed Endangered Has potential to be present No
Nearby Observed Species
Species documented by the Montana Natural Heritage Program (MNHP) within one mile of the investigation area are summarized in Table 2 (MNHP 2025). The complete MNHP Environmental Summary Report (ESR) for the project area is attached to this memo (Attachment 2). Most species listed here are unlikely to have habitat on the subject property due to habitat constraints. The subject property is an undeveloped field and wetland area, bordered to the east by Baxter Creek and N Laurel parkway to the west. Based on habitat, the species that have higher potential to occur on the subject property are the little brown myotis, bobolink, and the long-billed curlew.

Golden and Bald Eagle Occurrences
There are no documented eagle nests or range areas that intersect with the greater area around the investigation area (MNHP 2025).
Sage Grouse Habitat Review
The subject property does not contain sage grouse habitat (MT Sage Grouse Habitat Conservation Program 2025). See Figure 1 attached to this memo for a map of sage grouse habitat in the greater subject property area.
Wetland and Riparian Areas
The project area contains 6.76 acres of PEM wetland. Morrison-Maierle completed a wetland delineation in May of 2021 utilizing the methodology presented in the 1987 U.S. Army Corps of Engineers (USACE) Wetlands Delineation Manual (Environmental Laboratory 1987) and subsequent modifications outlined in the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast (Version 2.0) (Environmental Laboratory 2010). USACE determined these wetlands as non-jurisdictional via an Approved Jurisdictional Determination (AJD) on December 9, 2021 (NWO-2007-01084-MTH). A wetland delineation map is attached to this Memo (Figure 2), and the report is available upon request. The Wetland Mitigation and Monitoring Plan is also provided as Attachment 3.
Wetlands on the property connect to an adjacent pond and wetland complex, preserved from development. This area provides resources for migratory birds, amphibians, and other wildlife. Aquatic habitats offer food, cover, and breeding sites that are scarce in the surrounding developed landscape. Wetlands and ponds can function as small but critical refuges or stopover
4 | Page
points for migrating species, particularly in areas where natural habitats have been fragmented or replaced by residential and agricultural uses. The proximity of this habitat to the property increases the diversity of species likely to occur in the area, primarily those adapted to or tolerant of human activity.
Wildlife and Habitat Consideration
Construction of the proposed subdivision could temporarily disturb wildlife through noise, vegetation removal, and increased human presence. Wetlands and riparian corridors adjacent to the property provide habitat for migratory birds, amphibians, and small mammals; these resources could be indirectly affected by construction runoff, vegetation clearing, or reduced connectivity if not properly protected. At full build-out, increased residential activity, lighting, and domestic pets may further displace disturbance-sensitive species.
To help mitigate effects on wetland and their habitat in the project area, Morrison-Maierle has created a wetland mitigation plan to protect and preserve existing wetlands on the property. To offset wetland impacts, a 2.60-acre formerly disturbed area on the southeast area of the subject property, the location of an existing ponded borrow pit, will be converted to wetland. The southeastern area is adjacent to a wetland conservation deed-restricted area. This on-site wetland mitigation will create a more robust and biologically diverse wetland habitat with maximized connectivity. The wetland mitigation and monitoring plans details methods for this project and is attached to this memo (Attachment 2).
Wetlands at the project site will be monitored annually during peak growing season, between June and September, to assess project success and identify the need for maintenance and/or adaptive management strategies. The detailed monitoring plan is included in Attachment 2 of this memo.
Public Access The proposed project will result in increased public access within and adjacent to the Laurel Meadows Subdivision. The development includes the installation of a gravel walking trail along the east side of the subdivision within the designated open space/park area, creating a new publicly accessible route for pedestrian use. This will enhance local connectivity for neighborhood residents and provide an additional access point to the broader open-space network along Baxter Creek. Because the project area is bordered by existing residential development and is not currently used as formal public recreation land, the subdivision is not anticipated to reduce or restrict access to any existing public lands, regional trail system, or designated outdoor recreation areas such as hunting or fishing sites. Hunting is not permitted within the residential area, and no public fishing access sites occur within the adjacent property. Therefore, the project will have no adverse effect on the public’s ability to reach established hunting or fishing areas.
Protective Measures Several measures are incorporated into the Laurel Meadows Subdivision design to reduce impacts on wildlife, maintain habitat connectivity, and protect existing habitat resources. These include a combination of design considerations, mitigation actions, and long-term monitoring commitments that collectively minimize habitat degradation.
The wetland mitigation site will convert a heavily disturbed area into functional wetland habitat adjacent to a deed-restricted conservation area. This will create a larger tract of intact habitat rather than fragmenting it further with residential development. A 5-year monitoring period will
5 | Page
evaluate the project success, identify maintenance needs, and implement adaptive management if problems arise.
Additionally, guidance received from Montana Fish, Wildlife, and Parks, detailed below has been incorporated into the project design.
Design Considerations and FWP Guidance A letter was received from Montana Fish Wildlife and Parks (FWP) on November 11, 2025 regarding recommendations for Laurel Meadows Subdivision. Standard FWP recommendations for developments adjacent to riparian and wetland resources were recommended in the letter:
Maintaining undisturbed vegetated buffer zones around wetlands and Baxter Creek.
Preserving native vegetation along riparian corridors to support wildlife movement and prevent erosion.
Clustering development to minimize habitat fragmentation.
Implementing stormwater management practices to prevent sediment and pollutant runoff into aquatic habitats.
Incorporating these measures into subdivision planning will help protect wildlife resources and maintain habitat connectivity between the subject property and adjacent open space. The FWP letter is included as Attachment 4.
Mitigation Planned to Overcome Adverse Impacts In accordance with FWP recommendations, the project includes mitigation measures to reduce habitat disturbance including:
• Maintaining undisturbed, vegetated buffer zones around wetlands and along Baxter Creek.
• Preserving native vegetation in riparian corridors to support wildlife movement and reduce erosion.
• Buffers help protect habitats from construction and post-construction disturbances.
• Residential homes are clustered to reduce habitat fragmentation and preserve larger areas of intact open space.
• Stormwater will not outlet to Baxter Creek which will help prevent sediment and pollutants from entering wetlands and aquatic habitat during and after construction.
• Construction-related impacts such as noise, vegetation loss, and temporary ground disturbance will be mitigated by fencing off wetland/waterway buffers during construction, adhering to construction stormwater permitting requirements, and stabilizing disturbed areas once construction is completed.
Data Sources
This memo is informed by science-backed data sources, our expertise, and firsthand observations conducted on the subject property. The two key data sources described below provide much of the data presented above and inform our analysis.
The Montana Natural Heritage Program (MTNHP) collects and manages data on species occurrences, biological communities, and habitat across the state. Data is aggregated into a model and customized reports for a specified project area are provided from the MTNHP upon request. For these reports, the project area is buffered up to one square mile in all directions,
6 | Page
and the data is summarized to allow for “consistent and rapid delivery of summaries based on a uniform grid that has been used for planning efforts across the western United States” (MTNHP 2023). Thus, a species listed in a MTNHP data set as occurring within the project area may in fact have habitat in the larger, buffered, search area, and does not necessarily indicate habitat on the subject property.
Three categories of data are presented in this report:
1. Species occurrences for species of concern (this includes special status species and important animal habitat) 2. Other observed non-species of concern, or species of concern lacking enough data to be completely mapped 3. Other species that have not been documented in the buffered project area, but that could be present based on habitat distribution
The MNHP Environmental Survey Report (ESR) is summarized in Table 2 and attached to this memo.
The USFWS manages the Information for Planning and Consulting (IPaC) database, which provides information about federally protected plants, animals, and designated critical habitats that might be impacted by a proposed project.
The IPaC report generates a list of species and resources such as critical habitats that are under the jurisdiction of the USFWS and are known or expected to be present in or around the project area. This list may also include resources that are outside the project area but could potentially be affected by activities within the project area (USFWS 2023a). The results of this report are summarized in Table 1, the full report is attached to this memo.
Summary
There are (a) no direct observations of, and (b) no critical habitat for, T&E species on the subject property. Occurrences of several MNHP-defined species of concern were documented in the past within the greater project area, though most are unlikely to occur on the property due to inadequate habitat. The proposed subdivision has the potential to cause temporary construction-related disturbance and long-term habitat modification; however, implementation of standard FWP design considerations can help reduce impacts and preserve adjacent wetland and riparian habitat values.

IPaC resource list
This report is an automatically generated list of species and other resources such as critical
habitat (collectively referred to as trust resources) under the U.S. Fish and Wildlife Service's
(USFWS) jurisdiction that are known or expected to be on or near the project area referenced
below. The list may also include trust resources that occur outside of the project area, but that
could potentially be directly or indirectly affected by activities in the project area. However,
determining the likelihood and extent of effects a project may have on trust resources typically
requires gathering additional site-specific (e.g., vegetation/species surveys) and project-specific
(e.g., magnitude and timing of proposed activities) information.
Below is a summary of the project information you provided and contact information for the
USFWS office(s) with jurisdiction in the defined project area. Please read the introduction to each
section that follows (Endangered Species, Migratory Birds, USFWS Facilities, and NWI Wetlands)
for additional information applicable to the trust resources addressed in that section.

Endangered species
This resource list is for informational purposes only and does not constitute an analysis of
project level impacts.
The primary information used to generate this list is the known or expected range of each species.
Additional areas of influence (AOI) for species are also considered. An AOI includes areas outside
of the species range if the species could be indirectly affected by activities in that area (e.g.,
placing a dam upstream of a fish population even if that fish does not occur at the dam site, may
indirectly impact the species by reducing or eliminating water flow downstream). Because species
can move, and site conditions can change, the species on this list are not guaranteed to be found
on or near the project area. To fully determine any potential effects to species, additional site-
specific and project-specific information is often required.
Section 7 of the Endangered Species Act requires Federal agencies to "request of the Secretary
information whether any species which is listed or proposed to be listed may be present in the
area of such proposed action" for any project that is conducted, permitted, funded, or licensed by
any Federal agency. A letter from the local office and a species list which fulfills this requirement
can only be obtained by requesting an official species list from either the Regulatory Review
section in IPaC (see directions below) or from the local field office directly.
For project evaluations that require USFWS concurrence/review, please return to the IPaC
website and request an official species list by doing the following:
1. Draw the project location and click CONTINUE.
2. Click DEFINE PROJECT.
3. Log in (if directed to do so).
4. Provide a name and description for your project.
5. Click REQUEST SPECIES LIST.
Listed species and their critical habitats are managed by the Ecological Services Program of the
U.S. Fish and Wildlife Service (USFWS) and the fisheries division of the National Oceanic and
Atmospheric Administration (NOAA Fisheries ).
Species and critical habitats under the sole responsibility of NOAA Fisheries are not shown on
this list. Please contact NOAA Fisheries for species under their jurisdiction.
1. Species listed under the Endangered Species Act are threatened or endangered; IPaC also
shows species that are candidates, or proposed, for listing. See the listing status page for
more information. IPaC only shows species that are regulated by USFWS (see FAQ).

Measures for Proactively Minimizing Eagle Impacts
For information on how to best avoid and minimize disturbance to nesting bald eagles, please
review the National Bald Eagle Management Guidelines. You may employ the timing and activity-
specific distance recommendations in this document when designing your project/activity to avoid
and minimize eagle impacts. For bald eagle information specific to Alaska, please refer to Bald
Eagle Nesting and Sensitivity to Human Activity.
Bald and Golden Eagles are protected under the Bald and Golden Eagle Protection Act and the
Migratory Bird Treaty Act (MBTA) . Any person or organization who plans or conducts activities
that may result in impacts to Bald or Golden Eagles, or their habitats, should follow appropriate
regulations and consider implementing appropriate avoidance and minimization measures, as
described in the various links on this page.

The FWS does not currently have guidelines for avoiding and minimizing disturbance to nesting
Golden Eagles. For site-specific recommendations regarding nesting Golden Eagles, please
consult with the appropriate Regional Migratory Bird Office or Ecological Services Field Office.
If disturbance or take of eagles cannot be avoided, an incidental take permit may be available to
authorize any take that results from, but is not the purpose of, an otherwise lawful activity. For
assistance making this determination for Bald Eagles, visit the Do I Need A Permit Tool. For
assistance making this determination for golden eagles, please consult with the appropriate
Regional Migratory Bird Office or Ecological Services Field Office.
Ensure Your Eagle List is Accurate and Complete
If your project area is in a poorly surveyed area in IPaC, your list may not be complete and you
may need to rely on other resources to determine what species may be present (e.g. your local
FWS field office, state surveys, your own surveys). Please review the Supplemental Information
on Migratory Birds and Eagles, to help you properly interpret the report for your specified location,
including determining if there is sufficient data to ensure your list is accurate.
For guidance on when to schedule activities or implement avoidance and minimization measures

Information on Migratory Birds and Eagles", specifically the FAQ section titled "Proper
Interpretation and Use of Your Migratory Bird Report" before using or attempting to interpret this
report.
Probability of Presence ()
Each green bar represents the bird's relative probability of presence in the 10km grid cell(s) your
project overlaps during a particular week of the year. (A year is represented as 12 4-week
months.) A taller bar indicates a higher probability of species presence. The survey effort (see
below) can be used to establish a level of confidence in the presence score. One can have higher
confidence in the presence score if the corresponding survey effort is also high.
How is the probability of presence score calculated? The calculation is done in three steps:
1. The probability of presence for each week is calculated as the number of survey events in the
week where the species was detected divided by the total number of survey events for that
week. For example, if in week 12 there were 20 survey events and the Spotted Towhee was
found in 5 of them, the probability of presence of the Spotted Towhee in week 12 is 0.25.
2. To properly present the pattern of presence across the year, the relative probability of
presence is calculated. This is the probability of presence divided by the maximum probability
of presence across all weeks. For example, imagine the probability of presence in week 20 for
the Spotted Towhee is 0.05, and that the probability of presence at week 12 (0.25) is the
maximum of any week of the year. The relative probability of presence on week 12 is 0.25/0.25
= 1; at week 20 it is 0.05/0.25 = 0.2.
3. The relative probability of presence calculated in the previous step undergoes a statistical
conversion so that all possible values fall between 0 and 10, inclusive. This is the probability of
presence score.
To see a bar's probability of presence score, simply hover your mouse cursor over the bar.
Breeding Season ()
Yellow bars denote a very liberal estimate of the time-frame inside which the bird breeds across its
entire range. If there are no yellow bars shown for a bird, it does not breed in your project area.
Survey Effort ()
Vertical black lines superimposed on probability of presence bars indicate the number of surveys
performed for that species in the 10km grid cell(s) your project area overlaps. The number of
surveys is expressed as a range, for example, 33 to 64 surveys.
To see a bar's survey effort range, simply hover your mouse cursor over the bar.
No Data ()
A week is marked as having no data if there were no survey events for that week.
Survey Timeframe
Surveys from only the last 10 years are used in order to ensure delivery of currently relevant
information. The exception to this is areas off the Atlantic coast, where bird returns are based on
all years of available data, since data in these areas is currently much more sparse.

Bald & Golden Eagles FAQs
What does IPaC use to generate the potential presence of bald and golden eagles in my specified
location?
The potential for eagle presence is derived from data provided by the Avian Knowledge Network (AKN). The AKN
data is based on a growing collection of survey, banding, and citizen science datasets and is queried and filtered
to return a list of those birds reported as occurring in the 10km grid cell(s) which your project intersects, and that
have been identified as warranting special attention because they are an eagle (Bald and Golden Eagle
Protection Act requirements may apply).
Proper interpretation and use of your eagle report
On the graphs provided, please look carefully at the survey effort (indicated by the black vertical line) and for the
existence of the "no data" indicator (a red horizontal line). A high survey effort is the key component. If the survey
effort is high, then the probability of presence score can be viewed as more dependable. In contrast, a low
survey effort line or no data line (red horizontal) means a lack of data and, therefore, a lack of certainty about
presence of the species. This list is not perfect; it is simply a starting point for identifying what birds have the
potential to be in your project area, when they might be there, and if they might be breeding (which means nests
might be present). The list and associated information help you know what to look for to confirm presence and
helps guide you in knowing when to implement avoidance and minimization measures to eliminate or reduce
potential impacts from your project activities or get the appropriate permits should presence be confirmed.
How do I know if eagles are breeding, wintering, or migrating in my area?
To see what part of a particular bird's range your project area falls within (i.e. breeding, wintering, migrating, or
resident), you may query your location using the RAIL Tool and view the range maps provided for birds in your
area at the bottom of the profiles provided for each bird in your results. If an eagle on your IPaC migratory bird
species list has a breeding season associated with it (indicated by yellow vertical bars on the phenology graph in
your “IPaC PROBABILITY OF PRESENCE SUMMARY” at the top of your results list), there may be nests
present at some point within the timeframe specified. If "Breeds elsewhere" is indicated, then the bird likely does
not breed in your project area.
Interpreting the Probability of Presence Graphs
Each green bar represents the bird's relative probability of presence in the 10km grid cell(s) your project overlaps
during a particular week of the year. A taller bar indicates a higher probability of species presence. The survey
effort can be used to establish a level of confidence in the presence score.
How is the probability of presence score calculated? The calculation is done in three steps:

https://ipac.ecosphere.fws.gov/location/W3WVIJ6JGNCCZCOAWGJGRULC7M/resources 8/20
The probability of presence for each week is calculated as the number of survey events in the week where the
species was detected divided by the total number of survey events for that week. For example, if in week 12
there were 20 survey events and the Spotted Towhee was found in 5 of them, the probability of presence of the
Spotted Towhee in week 12 is 0.25.
To properly present the pattern of presence across the year, the relative probability of presence is calculated.
This is the probability of presence divided by the maximum probability of presence across all weeks. For
example, imagine the probability of presence in week 20 for the Spotted Towhee is 0.05, and that the probability
of presence at week 12 (0.25) is the maximum of any week of the year. The relative probability of presence on
week 12 is 0.25/0.25 = 1; at week 20 it is 0.05/0.25 = 0.2.
The relative probability of presence calculated in the previous step undergoes a statistical conversion so that all
possible values fall between 0 and 10, inclusive. This is the probability of presence score.
Breeding Season ()
Yellow bars denote a very liberal estimate of the time-frame inside which the bird breeds across its entire range.
If there are no yellow bars shown for a bird, it does not breed in your project area.
Survey Effort ()
Vertical black lines superimposed on probability of presence bars indicate the number of surveys performed for
that species in the 10km grid cell(s) your project area overlaps.
No Data ()
A week is marked as having no data if there were no survey events for that week.
Survey Timeframe
Surveys from only the last 10 years are used in order to ensure delivery of currently relevant information. The
exception to this is areas off the Atlantic coast, where bird returns are based on all years of available data, since
data in these areas is currently much more sparse.
Migratory birds
The Migratory Bird Treaty Act (MBTA) prohibits the take (including killing, capturing, selling,
trading, and transport) of protected migratory bird species without prior authorization by the
Department of Interior U.S. Fish and Wildlife Service (Service).

Measures for Proactively Minimizing Migratory Bird Impacts
Your IPaC Migratory Bird list showcases birds of concern, including Birds of Conservation
Concern (BCC), in your project location. This is not a comprehensive list of all birds found in your
project area. However, you can help proactively minimize significant impacts to all birds at your
project location by implementing the measures in the Nationwide avoidance and minimization
measures for birds document, and any other project-specific avoidance and minimization
measures suggested at the link Measures for avoiding and minimizing impacts to birds for the
birds of concern on your list below.
Ensure Your Migratory Bird List is Accurate and Complete
If your project area is in a poorly surveyed area, your list may not be complete and you may need
to rely on other resources to determine what species may be present (e.g. your local FWS field
office, state surveys, your own surveys). Please review the Supplemental Information on Migratory
Birds and Eagles document, to help you properly interpret the report for your specified location,
including determining if there is sufficient data to ensure your list is accurate.
For guidance on when to schedule activities or implement avoidance and minimization measures
to reduce impacts to migratory birds on your list, see the "Probability of Presence Summary"
below to see when these birds are most likely to be present and breeding in your project area.

Information on Migratory Birds and Eagles", specifically the FAQ section titled "Proper
Interpretation and Use of Your Migratory Bird Report" before using or attempting to interpret this
report.
Probability of Presence ()
Each green bar represents the bird's relative probability of presence in the 10km grid cell(s) your
project overlaps during a particular week of the year. (A year is represented as 12 4-week
months.) A taller bar indicates a higher probability of species presence. The survey effort (see
below) can be used to establish a level of confidence in the presence score. One can have higher
confidence in the presence score if the corresponding survey effort is also high.
How is the probability of presence score calculated? The calculation is done in three steps:
1. The probability of presence for each week is calculated as the number of survey events in the
week where the species was detected divided by the total number of survey events for that
week. For example, if in week 12 there were 20 survey events and the Spotted Towhee was
found in 5 of them, the probability of presence of the Spotted Towhee in week 12 is 0.25.
2. To properly present the pattern of presence across the year, the relative probability of
presence is calculated. This is the probability of presence divided by the maximum probability
of presence across all weeks. For example, imagine the probability of presence in week 20 for
the Spotted Towhee is 0.05, and that the probability of presence at week 12 (0.25) is the
maximum of any week of the year. The relative probability of presence on week 12 is 0.25/0.25
= 1; at week 20 it is 0.05/0.25 = 0.2.
3. The relative probability of presence calculated in the previous step undergoes a statistical
conversion so that all possible values fall between 0 and 10, inclusive. This is the probability of
presence score.
To see a bar's probability of presence score, simply hover your mouse cursor over the bar.
Breeding Season ()
Yellow bars denote a very liberal estimate of the time-frame inside which the bird breeds across its
entire range. If there are no yellow bars shown for a bird, it does not breed in your project area.
Survey Effort ()
Vertical black lines superimposed on probability of presence bars indicate the number of surveys
performed for that species in the 10km grid cell(s) your project area overlaps. The number of
surveys is expressed as a range, for example, 33 to 64 surveys.
To see a bar's survey effort range, simply hover your mouse cursor over the bar.
No Data ()
A week is marked as having no data if there were no survey events for that week.
Survey Timeframe
Surveys from only the last 10 years are used in order to ensure delivery of currently relevant
information. The exception to this is areas off the Atlantic coast, where bird returns are based on
all years of available data, since data in these areas is currently much more sparse.

Migratory Bird FAQs
Tell me more about avoidance and minimization measures I can implement to avoid or minimize impacts
to migratory birds.
Nationwide Avoidance & Minimization Measures for Birds describes measures that can help avoid and minimize
impacts to all birds at any location year-round. When birds may be breeding in the area, identifying the locations
of any active nests and avoiding their destruction is one of the most effective ways to minimize impacts. To see
when birds are most likely to occur and breed in your project area, view the Probability of Presence Summary.
Additional measures or permits may be advisable depending on the type of activity you are conducting and the
type of infrastructure or bird species present on your project site.
What does IPaC use to generate the list of migratory birds that potentially occur in my specified
location?
The Migratory Bird Resource List is comprised of Birds of Conservation Concern (BCC) and other species that
may warrant special attention in your project location, such as those listed under the Endangered Species Act or
the Bald and Golden Eagle Protection Act and those species marked as “Vulnerable”. See the FAQ “What are the
levels of concern for migratory birds?” for more information on the levels of concern covered in the IPaC
migratory bird species list.
8/7/25, 4:49 PM IPaC: Explore Location resources
https://ipac.ecosphere.fws.gov/location/W3WVIJ6JGNCCZCOAWGJGRULC7M/resources 15/20
The migratory bird list generated for your project is derived from data provided by the Avian Knowledge Network
(AKN). The AKN data is based on a growing collection of survey, banding, and citizen science datasets and is
queried and filtered to return a list of those birds reported as occurring in the 10km grid cell(s) with which your
project intersects. These species have been identified as warranting special attention because they are BCC
species in that area, an eagle (Bald and Golden Eagle Protection Act requirements may apply), or a species that
has a particular vulnerability to offshore activities or development.
Again, the Migratory Bird Resource list includes only a subset of birds that may occur in your project area. It is
not representative of all birds that may occur in your project area. To get a list of all birds potentially present in
your project area, and to verify survey effort when no results present, please visit the Rapid Avian Information
Locator (RAIL) Tool.
Why are subspecies showing up on my list?
Subspecies profiles are included on the list of species present in your project area because observations in the
AKN for the species are being detected. If the species are present, that means that the subspecies may also be
present. If a subspecies shows up on your list, you may need to rely on other resources to determine if that
subspecies may be present (e.g. your local FWS field office, state surveys, your own surveys).
What does IPaC use to generate the probability of presence graphs for the migratory birds potentially
occurring in my specified location?
The probability of presence graphs associated with your migratory bird list are based on data provided by the
Avian Knowledge Network (AKN). This data is derived from a growing collection of survey, banding, and citizen
science datasets.
Probability of presence data is continuously being updated as new and better information becomes available. To
learn more about how the probability of presence graphs are produced and how to interpret them, go to the
Probability of Presence Summary and then click on the "Tell me about these graphs" link.
How do I know if a bird is breeding, wintering, or migrating in my area?
To see what part of a particular bird's range your project area falls within (i.e. breeding, wintering, migrating, or
resident), you may query your location using the RAIL Tool and view the range maps provided for birds in your
area at the bottom of the profiles provided for each bird in your results. If a bird on your IPaC migratory bird
species list has a breeding season associated with it (indicated by yellow vertical bars on the phenology graph in
your “IPaC PROBABILITY OF PRESENCE SUMMARY” at the top of your results list), there may be nests
present at some point within the timeframe specified. If "Breeds elsewhere" is indicated, then the bird likely does
not breed in your project area.
What are the levels of concern for migratory birds?
Migratory birds delivered through IPaC fall into the following distinct categories of concern:
1. "BCC Rangewide" birds are Birds of Conservation Concern (BCC) that are of concern throughout their range
anywhere within the USA (including Hawaii, the Pacific Islands, Puerto Rico, and the Virgin Islands);
2. "BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation Regions (BCRs) in the
continental USA; and
3. "Non-BCC - Vulnerable" birds are not BCC species in your project area, but appear on your list either
because of the Bald and Golden Eagle Protection Act requirements (for eagles) or (for non-eagles) potential

susceptibilities in offshore areas from certain types of development or activities (e.g. offshore energy
development or longline fishing).
Although it is important to avoid and minimize impacts to all birds, efforts should be made, in particular, to avoid
and minimize impacts to the birds on this list, especially BCC species. For more information on avoidance and
minimization measures you can implement to help avoid and minimize migratory bird impacts, please see the
FAQ “Tell me more about avoidance and minimization measures I can implement to avoid or minimize impacts to
migratory birds”.
Details about birds that are potentially affected by offshore projects
For additional details about the relative occurrence and abundance of both individual bird species and groups of
bird species within your project area off the Atlantic Coast, please visit the Northeast Ocean Data Portal. The
Portal also offers data and information about other taxa besides birds that may be helpful to you in your project
review. Alternately, you may download the bird model results files underlying the portal maps through the NOAA
NCCOS Integrative Statistical Modeling and Predictive Mapping of Marine Bird Distributions and Abundance on
the Atlantic Outer Continental Shelf project webpage.
Proper interpretation and use of your migratory bird report
The migratory bird list generated is not a list of all birds in your project area, only a subset of birds of priority
concern. To learn more about how your list is generated and see options for identifying what other birds may be
in your project area, please see the FAQ "What does IPaC use to generate the migratory birds potentially
occurring in my specified location". Please be aware this report provides the "probability of presence" of birds
within the 10 km grid cell(s) that overlap your project; not your exact project footprint. On the graphs provided,
please look carefully at the survey effort (indicated by the black vertical line) and for the existence of the "no
data" indicator (a red horizontal line). A high survey effort is the key component. If the survey effort is high, then
the probability of presence score can be viewed as more dependable. In contrast, a low survey effort bar or no
data bar means a lack of data and, therefore, a lack of certainty about presence of the species. This list does not
represent all birds present in your project area. It is simply a starting point for identifying what birds of concern
have the potential to be in your project area, when they might be there, and if they might be breeding (which
means nests might be present). The list and associated information help you know what to look for to confirm
presence and helps guide implementation of avoidance and minimization measures to eliminate or reduce
potential impacts from your project activities, should presence be confirmed. To learn more about avoidance and
minimization measures, visit the FAQ "Tell me about avoidance and minimization measures I can implement to
avoid or minimize impacts to migratory birds".
Interpreting the Probability of Presence Graphs
Each green bar represents the bird's relative probability of presence in the 10km grid cell(s) your project overlaps

of presence at week 12 (0.25) is the maximum of any week of the year. The relative probability of presence on
week 12 is 0.25/0.25 = 1; at week 20 it is 0.05/0.25 = 0.2.

Impacts to NWI wetlands and other aquatic habitats may be subject to regulation under Section
404 of the Clean Water Act, or other State/Federal statutes.
For more information please contact the Regulatory Program of the local U.S. Army Corps of
Engineers District.
Please note that the NWI data being shown may be out of date. We are currently working to
update our NWI data set. We recommend you verify these results with a site visit to determine the
actual extent of wetlands on site.
This location overlaps the following wetlands:
NOTE: This initial screening does not replace an on-site delineation to determine whether
wetlands occur. Additional information on the NWI data is provided below.
Data limitations
The Service's objective of mapping wetlands and deepwater habitats is to produce reconnaissance level
information on the location, type and size of these resources. The maps are prepared from the analysis of high
altitude imagery. Wetlands are identified based on vegetation, visible hydrology and geography. A margin of error
is inherent in the use of imagery; thus, detailed on-the-ground inspection of any particular site may result in
revision of the wetland boundaries or classification established through image analysis.
The accuracy of image interpretation depends on the quality of the imagery, the experience of the image
analysts, the amount and quality of the collateral data and the amount of ground truth verification work
conducted. Metadata should be consulted to determine the date of the source imagery used and any mapping
problems.
Wetlands or other mapped features may have changed since the date of the imagery or field work. There may be
occasional differences in polygon boundaries or classifications between the information depicted on the map and
the actual conditions on site.

Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial
imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged
aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and nearshore coastal waters.
Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory.
These habitats, because of their depth, go undetected by aerial imagery.
Data precautions
Federal, state, and local regulatory agencies with jurisdiction over wetlands may define and describe wetlands in
a different manner than that used in this inventory. There is no attempt, in either the design or products of this
inventory, to define the limits of proprietary jurisdiction of any Federal, state, or local government or to establish
the geographical scope of the regulatory programs of government agencies. Persons intending to engage in
activities involving modifications within or adjacent to wetland areas should seek the advice of appropriate
Federal, state, or local agencies concerning specified agency regulatory programs and proprietary jurisdictions
that may affect such activities.

Introduction to Environmental Summary Report
Environmental Summary Reports from the Montana Natural Heritage Program (MTNHP) provide information
on species and biological communities to inform all stakeholders in environmental review, permitting, and
planning processes. For information on environmental permits in Montana, please see permitting overviews
by the Montana Department of Environmental Quality, the Montana Department of Natural Resources and
Conservation, the Index of Environmental Permits for Montana and our Suggested Contacts for Natural
Resource Management Agencies. The report for your area of interest consists of introductory and related
materials in this PDF and an Excel workbook with worksheets summarizing information managed in the
MTNHP databases for: (1) species occurrences; (2) other observed species without species occurrences; (3)
other species potentially present based on their range, presence of associated habitats, or predictive
distribution model output if available; (4) structured surveys that follow a protocol capable of detecting one or
more species; (5) land cover mapped as ecological systems; (6) wetland and riparian mapping; (7) land
management categories; and (8) biological reports associated with plant and animal observations. If your area
of interest corresponds to a statewide polygon layer (e.g., watersheds, counties, or public land survey
sections) information summaries in your report will exactly match those boundaries. However, if your report
is for a custom area, users should be aware that summaries do not correspond to the exact boundaries of the
polygon they have specified, but instead are a summary across a layer of hexagons intersected by the polygon
they specified as shown on the report cover. Summarizing by these hexagons which are one square mile in
area and approximately one kilometer in length on each side allows for consistent and rapid delivery of
summaries based on a uniform grid that has been used for planning efforts across North America.
In presenting this information, MTNHP is working towards assisting the user with rapidly assessing the known
or potential species and biological communities, land management categories, and biological reports
associated with the report area. Users are reminded that this information is likely incomplete and may be
inaccurate as surveys to document species are lacking in many areas of the state, species’ range polygons
often include regions of unsuitable habitat, methods of predicting the presence of species or communities are
constantly improving, and information is constantly being added and updated in our databases. Field
verification by professional biologists of the absence or presence of species and biological communities in a
report area will always be an important obligation of users of our data. Users are encouraged to only use
this environmental summary report as a starting point for more in depth analyses and are encouraged to
contact state, federal, and tribal resource management agencies for additional data or management
guidelines relevant to your efforts. Please see the Appendix for introductory materials to each section of
the report, additional information resources, and a list of relevant agency contacts.

Structured Surveys
Summarized by: CS0727212 (Custom Area of Interest)
The Montana Natural Heritage Program (MTNHP) records informa on on the loca ons where more than 80 different types of well-defined repeatable survey protocols capable of detec ng an
animal species or suite of animal species have been conducted by state, federal, tribal, university, or private consul ng biologists. Examples of structured survey protocols tracked by MTNHPinclude: visual encounter and dip net surveys for pond breeding amphibians, point counts for birds, call playback surveys for selected bird species, visual surveys of migra ng raptors, kick net
stream reach surveys for macroinvertebrates, visual encounter cover object surveys for terrestrial mollusks, bat acous c or mist net surveys, pi all and/or snap trap surveys for small terrestrial
mammals, track or camera trap surveys for large mammals, and trap surveys for turtles. Whenever possible, photographs of survey loca ons are stored in MTNHP databases.
MTNHP does not typically manage informa on on structured surveys for plants; surveys for invasive species may be a future excep on.
Within the report area you have requested, structured surveys are summarized by the number of each type of structured survey protocol that has been conducted, the number of species
detec ons/observa ons resul ng from these surveys, and the most recent year a survey has been conducted.

Land Cover
Summarized by: CS0727212 (Custom Area of Interest)
30% (1,906Acres)
Human Land Use
Agriculture
Cultivated Crops
These areas used for the production of crops, such as corn, soybeans, small grains, sunflowers, vegetables, and cotton, typically on an annual
cycle. Agricultural plant cover is variable depending on season and type of farming. Other areas include more stable land cover of orchards andvineyards.
26% (1,678Acres)
Grassland Systems
Montane Grassland
Rocky Mountain Lower Montane, Foothill, and Valley Grassland
This grassland system of the northern Rocky Mountains is found at lower montane to foothill elevations in mountains and valleys throughout
Montana. These grasslands are floristically similar to Big Sagebrush Steppe but are defined by shorter summers, colder winters, and youngsoils derived from recent glacial and alluvial material. They are found at elevations from 548 - 1,650 meters (1,800-5,413 feet). In the lower
montane zone, they range from small meadows to large open parks surrounded by conifers; below the lower treeline, they occur as extensive
foothill and valley grasslands. Soils are relatively deep, fine-textured, often with coarse fragments, and non-saline. Microphytic crust may bepresent in high-quality occurrences. This system is typified by cool-season perennial bunch grasses and forbs (>25%) cover, with a sparse
shrub cover (<10%). Rough fescue (Festuca campestris) is dominant in the northwestern portion of the state and Idaho fescue (Festuca
idahoensis) is dominant or co-dominant throughout the range of the system. Bluebunch wheatgrass (Pseudoroegneria spicata) occurs as aco-dominant throughout the range as well, especially on xeric sites. Western wheatgrass (Pascopyrum smithii) is consistently present, often
with appreciable coverage (>10%) in lower elevation occurrences in western Montana and virtually always present, with relatively highcoverages (>25%), on the edge of the Northwestern Great Plains region. Species diversity ranges from a high of more than 50 per 400square meter plot on mesic sites to 15 (or fewer) on xeric and disturbed sites. Most occurrences have at least 25 vascular species present.
Farmland conversion, noxious species invasion, fire suppression, heavy grazing and oil and gas development are major threats to thissystem.

INTRODUCTION
The Montana Natural Heritage Program (MTNHP) is Montana’s source for reliable and objective information
on Montana’s native species and habitats, emphasizing those of conservation concern. MTNHP was created
by the Montana legislature in 1983 as part of the Natural Resource Information System (NRIS) at the Montana
State Library (MSL). MTNHP is “a program of information acquisition, storage, and retrieval for data relating
to the flora, fauna, and biological community types of Montana” (MCA 90-15-102). MTNHP’s activities are
guided by statute as well as through ongoing interaction with, and feedback from, principal data source
agencies such as Montana Fish, Wildlife, and Parks, the Montana Department of Environmental Quality, the
Montana Department of Natural Resources and Conservation, the Montana University System, the US Forest
Service, and the US Bureau of Land Management. Since the first staff was hired in 1985, the Program has
logged a long record of success, and developed into a highly respected, service-oriented program. MTNHP is
widely recognized as one of the most advanced and effective of over 60 natural heritage programs that are
distributed across North America.
VISION
Our vision is that public agencies, the private sector, the education sector, and the general public will trust and
rely upon MTNHP as the source for information and expertise on Montana’s species and habitats, especially
those of conservation concern. We strive to provide easy access to our information to allow users to save
time and money, speed environmental reviews, and make informed decisions.
CORE VALUES
• We endeavor to be a single statewide source of accurate and up-to-date information on Montana’s plants,
animals, and aquatic and terrestrial biological communities.
• We actively listen to our data users and work responsively to meet their information and training needs.
• We strive to provide neutral, trusted, timely, and equitable service to all of our information users.
• We make every effort to be transparent to our data users in setting work priorities and providing data
products.
CONFIDENTIALITY
All information requests made to the Montana Natural Heritage Program are considered library records and
are protected from disclosure by the Montana Library Records Confidentiality Act (MCA 22-1-11).
INFORMATION MANAGED
Information managed at the Montana Natural Heritage Program is botanical, zoological, and ecological
information that describes the distribution (e.g., observations, structured surveys, range polygons, predicted
habitat suitability models), conservation status (e.g., global and state conservation status ranks, including
threats), and other supporting information (e.g., accounts and references) on the biology and ecology of
species and biological communities.

Data Use Terms and Conditions
• Montana Natural Heritage Program (MTNHP) products and services are based on biological data and the objective
interpretation of those data by professional scientists. MTNHP does not advocate any particular philosophy of natural
resource protection, management, development, or public policy.
• MTNHP has no natural resource management or regulatory authority. Products, statements, and services from
MTNHP are intended to inform parties as to the state of scientific knowledge about certain natural resources, and to
further develop that knowledge. The information is not intended as natural resource management guidelines or
prescriptions or a determination of environmental impacts. MTNHP recommends consultation with appropriate
state, federal, and tribal resource management agencies and authorities in the area where your project is located.
• Information on the status and spatial distribution of biological resources produced by MTNHP are intended to inform
parties of the state-wide status, known occurrence, or the likelihood of the presence of those resources. These
products are not intended to substitute for field-collected data, nor are they intended to be the sole basis for
natural resource management decisions.
• MTNHP does not portray its data as exhaustive or comprehensive inventories of rare species or biological
communities. Field verification of the absence or presence of sensitive species and biological communities will
always be an important obligation of users of our data.
• MTNHP responds equally to all requests for products and services, regardless of the purpose or identity of the
requester.
• Because MTNHP constantly updates and revises its databases with new data and information, products will become
outdated over time. Interested parties are encouraged to obtain the most current information possible from MTNHP,
rather than using older products. We add, review, update, and delete records on a daily basis. Consequently, we
strongly advise that you update your MTNHP data sets at a minimum of every four months for most applications of
our information.
• MTNHP data require a certain degree of biological expertise for proper analysis, interpretation, and application. Our
staff is available to advise you on questions regarding the interpretation or appropriate use of the data that we
provide. See Contact Information for MTNHP Staff
• The information provided to you by MTNHP may include sensitive data that if publicly released might jeopardize the
welfare of threatened, endangered, or sensitive species or biological communities. This information is intended for
distribution or use only within your department, agency, or business. Subcontractors may have access to the data
during the course of any given project, but should not be given a copy for their use on subsequent, unrelated work.
• MTNHP data are made freely available. Duplication of hard-copy or digital MTNHP products with the intent to sell is
prohibited without written consent by MTNHP. Should you be asked by individuals outside your organization for the
type of data that we provide, please refer them to MTNHP.
• MTNHP and appropriate staff members should be appropriately acknowledged as an information source in any third-
party product involving MTNHP data, reports, papers, publications, or in maps that incorporate MTNHP graphic
elements.
• Sources of our data include museum specimens, published and unpublished scientific literature, field surveys by state
and federal agencies and private contractors, and reports from knowledgeable individuals. MTNHP actively solicits
and encourages additions, corrections and updates, new observations or collections, and comments on any of the
data we provide.
• MTNHP staff and contractors do not enter or cross privately-owned lands without express permission from the
landowner. However, the program cannot guarantee that information provided to us by others was obtained under
adherence to this policy.

Suggested Contacts for Natural Resource Management Agencies
As required by Montana statute (MCA 90-15), the Montana Natural Heritage Program works with state,
federal, tribal, nongovernmental organizations, and private partners to ensure that the latest animal and plant
distribution and status information is incorporated into our databases so that it can be used to inform a
variety of permitting and planning processes and management decisions. We encourage you to contact state,
federal, and tribal resource management agencies in the area where your project is located and review the
permitting overviews by the Montana Department of Environmental Quality, the Montana Department of
Natural Resources and Conservation and the Index of Environmental Permits for Montana for guidelines
relevant to your efforts. In particular, we encourage you to contact the Montana Department of Fish, Wildlife,
and Parks for the latest data and management information regarding hunted and high-profile management
species and to use the U.S. Fish and Wildlife Service’s Information Planning and Consultation (IPAC) website
regarding U.S. Endangered Species Act listed Threatened, Endangered, or Candidate species.

Introduction to Native Species
Within the report area you have requested, separate summaries are provided for: (1) Species Occurrences (SO)
for plant and animal Species of Concern, Special Status Species (SSS), Important Animal Habitat (IAH) and some
Potential Plant Species of Concern; (2) other observed non Species of Concern or Species of Concern without
suitable documentation to create Species Occurrence polygons; and (3) other non-documented species that are
potentially present based on their range, predicted suitable habitat model output, or presence of associated
habitats. Each of these summaries provides the following information when present for a species: (1) the
number of Species Occurrences and associated delineation criteria for construction of these polygons that have
long been used for considerations of documented Species of Concern in environmental reviews; (2) the number
of observations of each species; (3) the geographic range polygons for each species that the report area
overlaps; (4) predicted relative habitat suitability classes that are present if a predicted suitable habitat model
has been created; (5) the percent of the report area that is mapped as commonly associated or occasionally
associated habitat as listed for each species in the Montana Field Guide; and (6) a variety of conservation status
ranks and links to species accounts in the Montana Field Guide. Details on each of these information categories
are included under relevant section headers below or are defined on our Species Status Codes page. In
presenting this information, the Montana Natural Heritage Program (MTNHP) is working towards assisting the
user with rapidly determining what species have been documented and what species are potentially present in
the report area. We remind users that this information is likely incomplete as surveys to document native and
introduced species are lacking in many areas of the state, information on introduced species has only been
tracked relatively recently, the MTNHP’s staff and resources are restricted by budgets, and information is
constantly being added and updated in our databases. Thus, field verification by professional biologists of the
absence or presence of species and biological communities will always be an important obligation of users of
our data.
If you are aware of observation datasets that the MTNHP is missing, please report them to the Program Botanist
apipp@mt.gov or Senior Zoologist dbachen@mt.gov If you have animal or plant observations that you would
like to contribute, you can also submit them via Excel spreadsheets, geodatabases, iNaturalist, or a Survey123
form. Various methods of data submission are reviewed in this playlist of videos:
https://www.youtube.com/playlist?list=PLRaydtZpHu2qOHPoSPq9cnM9uXGmEXACx
Observations
The MTNHP manages information on several million animal and plant observations that have been reported by
professional biologists and private citizens from across Montana. The majority of these observations are
submitted in digital format from standardized databases associated with research or monitoring efforts and
spreadsheets of incidental observations submitted by professional biologists and amateur naturalists. At a
minimum, accepted observation records must contain a credible species identification (i.e. appropriate
geographic range, date, and habitat and, if species are difficult to identify, a photograph and/or notes on key
identifying features), a date or date range, observer name, locational information (ideally with latitude and
longitude in decimal degrees), notes on numbers observed, and species behavior or habitat use (e.g., is the
observation likely associated with reproduction). Bird records are also required to have information associated
with date-appropriate breeding or overwintering status of the species observed. MTNHP reviews observation
records to ensure that they are mapped correctly, occur within date ranges when the species is known to be
present or detectable, occur within the known seasonal geographic range of the species, and occur in
appropriate habitats. MTNHP also assigns each record a locational uncertainty value in meters to indicate the
spatial precision associated with the record’s mapped coordinates. Only records with locational uncertainty
values of 10,000 meters or less are included in environmental summary reports and number summaries are only
provided for records with locational uncertainty values of 1,000 meters or less.
Page 28 of 35
Species Occurrences
The MTNHP evaluates plant and animal observation records for species of higher conservation concern to
determine whether they are worthy of inclusion in the Species Occurrence (SO) layer for use in environmental
reviews; observations not worthy of inclusion in this layer include long distance dispersal events, migrants
observed away from key migratory stopover habitats, and winter observations. An SO is a polygon depicting
what is known about a species occupancy from direct observation with a defined level of locational uncertainty
and any inference that can be made about adjacent habitat use from the latest peer-reviewed science. If an
observation can be associated with a map feature that can be tracked (e.g., a wetland boundary for a wetland
associated plant) then this polygon feature is used to represent the SO. Areas that can be inferred as probable
occupied habitat based on direct observation of a species location and what is known about the foraging area or
home range size of the species may be incorporated into the SO. Species Occurrences generally belong to one of
the following categories:
Plant Species Occurrences
A documented location of a specimen collection or observed plant population. In some instances, adjacent,
spatially separated clusters are considered subpopulations and are grouped as one occurrence (e.g., the
subpopulations occur in ecologically similar habitats, and their spatial proximity likely allows them to
interbreed). Tabular information for multiple observations at the same SO location is generally linked to a
single polygon. Plant SO's are only created for Species of Concern and Potential Species of Concern.
Animal Species Occurrences
The location of a verified observation or specimen record typically known or assumed to represent a breeding
population or a portion of a breeding population. Animal SO’s are generally: (1) buffers of terrestrial point
observations based on documented species’ home range sizes; (2) buffers of stream segments to encompass
occupied streams and immediate adjacent riparian habitats; (3) polygonal features encompassing known or
likely breeding populations (e.g., a wetland for some amphibians or a forested portion of a mountain range
for some wide-ranging carnivores); or (4) combinations of the above. Tabular information for multiple
observations at the same SO location is generally linked to a single polygon. Species Occurrence polygons
may encompass some unsuitable habitat in some instances in order to avoid heavy data processing associated
with clipping out habitats that are readily assessed as unsuitable by the data user (e.g., a point buffer of a
terrestrial species may overlap into a portion of a lake that is obviously inappropriate habitat for the species).
Animal SO's are only created for Species of Concern and Special Status Species (e.g., Bald Eagle).
Other Occurrence Polygons
These include significant biological features not included in the above categories, such as Important Animal
Habitats like bird rookeries and bat roosts, and peatlands or other wetland and riparian communities that
support diverse plant and animal communities.
Page 29 of 35
Geographic Range Polygons
Geographic range polygons are still under development for most plant and invertebrate species. Native year-
round, summer, winter, migratory and historic geographic range polygons as well as polygons for introduced
populations have been defined for most
vertebrate animal species for which there are
enough observations, surveys, and knowledge of
appropriate seasonal habitat use to define them
(see examples to left). These native or introduced
range polygons bound the extent of known or
likely occupied habitats for non-migratory and
relative sedentary species and the regular extent
of known or likely occupied habitats for migratory
and long-distance dispersing species; polygons
may include unsuitable intervening habitats. For
most species, a single polygon can represent the
year-round or seasonal range, but breeding
ranges of some colonial nesting water birds and
some introduced species are represented more
patchily when supported by data. Some ranges
are mapped more broadly than actual
distributions in order to be visible on statewide
maps (e.g., fish).
Predicted Suitable Habitat Models
Predicted habitat suitability models have been created for plant and animal Species of Concern and are
undergoing development for non-Species of Concern. For species for which models have been completed, the
environmental summary report includes simple rule-based associations with streams for aquatic species and
seasonal habitats for game species as well as mathematically complex Maximum Entropy models (Phillips et al.
2006, Ecological Modeling 190:231-259) constructed from a variety of statewide biotic and abiotic layers and
presence only data for individual species for most terrestrial species. For the Maximum Entropy models, we
reclassified 90 x 90-meter continuous model output into suitability classes (unsuitable, low, moderate, and
optimal) then aggregated that into the one square mile hexagons used in the environmental summary report;
this is the finest spatial scale we suggest using this information in management decisions and survey planning.
Full model write ups for individual species that discuss model goals, inputs, outputs, and evaluation in much
greater detail are posted on the MTNHP’s Predicted Suitable Habitat Models webpage. Evaluations of
predictive accuracy and specific limitations are included with the metadata for models of individual species.
Model outputs should not be used in place of on-the-ground surveys for species. Instead model outputs
should be used in conjunction with habitat evaluations to determine the need for on-the-ground surveys for
species. We suggest that the percentage of predicted optimal and moderate suitable habitat within the
report area be used in conjunction with geographic range polygons and the percentage of commonly
associated habitats to generate lists of potential species that may occupy broader landscapes for the purposes
of landscape-level planning.
Associated Habitats
Within the boundary of the intersected hexagons, we provide the approximate percentage of commonly or
occasionally associated habitat for vertebrate animal species that regularly breed, overwinter, or migrate
through the state; a detailed list of commonly and occasionally associated habitats is provided in individual
species accounts in the Montana Field Guide We assigned common or occasional use of each of the ecological
Page 30 of 35
systems mapped in Montana by: (1) using personal knowledge and reviewing literature that summarizes the
breeding, overwintering, or migratory habitat requirements of each species; (2) evaluating structural
characteristics and distribution of each ecological system relative to the species’ range and habitat
requirements; (3) examining the observation records for each species in the state-wide point observation
database associated with each ecological system; and (4) calculating the percentage of observations
associated with each ecological system relative to the percent of Montana covered by each ecological system
to get a measure of numbers of observations versus availability of habitat. Species that breed in Montana
were only evaluated for breeding habitat use, species that only overwinter in Montana were only evaluated
for overwintering habitat use, and species that only migrate through Montana were only evaluated for
migratory habitat use. In general, species were listed as associated with an ecological system if structural
characteristics of used habitat documented in the literature were present in the ecological system or large
numbers of point observations were associated with the ecological system. However, species were not listed
as associated with an ecological system if there was no support in the literature for use of structural
characteristics in an ecological system, even if point observations were associated with that system. Common
versus occasional association with an ecological system was assigned based on the degree to which the
structural characteristics of an ecological system matched the preferred structural habitat characteristics for
each species as represented in the scientific literature. The percentage of observations associated with each
ecological system relative to the percent of Montana covered by each ecological system was also used to
guide assignment of common versus occasional association.
We suggest that the percentage of commonly associated habitat within the report area be used in conjunction
with geographic range polygons and the percentage of predicted optimal and moderate suitable habitat from
predictive models to generate lists of potential species that may occupy broader landscapes for the purposes
of landscape-level planning. Users of this information should be aware that land cover mapping accuracy is
particularly problematic when the systems occur as small patches or where the land cover types have been
altered over the past decade. Thus, particular caution should be used when using the associations in
assessments of smaller areas (e.g., evaluations of public land survey sections).

Introduction to Land Cover
Land Use/Land Cover is one of 15 Montana Spatial Data Infrastructure framework layers considered vital for
making statewide maps of Montana and understanding its geography. The layer records all Montana natural
vegetation, land cover and land use, classified from satellite and aerial imagery, mapped at a scale of
1:100,000, and interpreted with supporting ground-level data. The baseline map is adapted from the
Northwest ReGAP (NWGAP) project land cover classification, which used 30m resolution multi-spectral
Landsat imagery acquired between 1999 and 2001. Vegetation classes were drawn from the Ecological System
Classification developed by NatureServe (Comer et al. 2003). The land cover classes were developed by
Anderson et al. (1976). The NWGAP effort encompasses 12 map zones. Montana overlaps seven of these
zones. The two NWGAP teams responsible for the initial land cover mapping effort in Montana were Sanborn
and NWGAP at the University of Idaho. Both Sanborn and NWGAP employed a similar modeling approach in
which Classification and Regression Tree (CART) models were applied to Landsat ETM+ scenes. The Spatial
Analysis Lab within the Montana Natural Heritage Program was responsible for developing a seamless
Montana land cover map with a consistent statewide legend from these two separate products. Additionally,
the Montana land cover layer incorporates several other land cover and land use products (e.g., MSDI
Structures and Transportation themes and the Montana Department of Revenue Final Land Unit classification)
and reclassifications based on plot-level data and the latest NAIP imagery to improve accuracy and enhance
the usability of the theme. Updates are done as partner support and funding allow, or when other MSDI
datasets can be incorporated. Recent updates include fire perimeters and agricultural land use (annually),
energy developments such as wind, oil and gas installations (2014), roads, structures and other impervious
surfaces (various years): and local updates/improvements to specific ecological systems (e.g., central Montana
grassland and sagebrush ecosystems). Current and previous versions of the Land Use/Land Cover layer with
full metadata are available for download from the Montana State Library’s GIS Data List More information on
the land cover layer is available at: https://msl.mt.gov/geoinfo/msdi/land_use_land_cover/
Within the report area you have requested, land cover is summarized by acres of Level 1, Level 2, and Level 3

Introduction to Wetland and Riparian
Within the report area you have requested, wetland and riparian mapping is summarized by acres of each
classification present. Summaries are only provided for modern MTNHP wetland and riparian mapping and
not for outdated (NWI Legacy) or incomplete (NWI Scalable) mapping efforts; described here. MTNHP has
made all three of these datasets and associated metadata available for separate download on the Montana
Wetland and Riparian Framework web page.
Wetland and Riparian mapping is one of 15 Montana Spatial Data Infrastructure framework layers considered
vital for making statewide maps of Montana and understanding its geography. The wetland and riparian
framework layer consists of spatial data representing the extent, type, and approximate location of wetlands,
riparian areas, and deep water habitats in Montana.
Wetland and riparian mapping is completed through photointerpretation of 1-m resolution color infrared
aerial imagery acquired from 2005 or later. A coding convention using letters and numbers is assigned to each
mapped wetland. These letters and numbers describe the broad landscape context of the wetland, its
vegetation type, its water regime, and the kind of alterations that may have occurred. Ancillary data layers
such as topographic maps, digital elevation models, soils data, and other aerial imagery sources are also used
to improve mapping accuracy. Wetland mapping follows the federal Wetland Mapping Standard and classifies
wetlands according to the Cowardin classification system of the National Wetlands Inventory (NWI) (Cowardin
et al. 1979, FGDC Wetlands Subcommittee 2013). Federal, State, and local regulatory agencies with
jurisdiction over wetlands may define and describe wetlands differently than the NWI. Similar coding, based
on U.S. Fish and Wildlife Service conventions, is applied to riparian areas (U.S. Fish and Wildlife Service
2009). These are mapped areas where vegetation composition and growth is influenced by nearby water
bodies, but where soils, plant communities, and hydrology do not display true wetland characteristics. These
data are intended for use at a scale of 1:12,000 or smaller. Mapped wetland and riparian areas do not
represent precise boundaries and digital wetland data cannot substitute for an on-site determination of
jurisdictional wetlands.

codes as a storymap and companion guide

Introduction to Land Management
Within the report area you have requested, land management information is summarized by acres of federal,
state, and local government lands, tribal reservation boundaries, private conservation lands, and federal,
state, local, and private conservation easements. Acreage for “Owned”, “Tribal”, or “Easement” categories
represents non-overlapping areas that may be totaled. However, “Other Boundaries” represents managed
areas such as National Forest boundaries containing private inholdings and other mixed ownership which may
cause boundaries to overlap (e.g. a wilderness area within a forest). Therefore, acreages may not total in a
straight-forward manner.
Because information on land stewardship is critical to effective land management, the Montana Natural
Heritage Program (MTNHP) began compiling ownership and management data in 1997. The goal of the
Montana Land Management Database is to manage a single, statewide digital data set that incorporates
information from both public and private entities. The database assembles information on public lands,
private conservation lands, and conservation easements held by state and federal agencies and land trusts and
is updated on a regular basis. Since 2011, the Information Management group in the Montana State Library’s
Digital Library Division has led the Montana Land Management Database in partnership with the MTNHP.
Public and private conservation land polygons are attributed with the name of the entity that owns it. The
data are derived from the statewide Montana Cadastral Parcel layer Conservation easement data shows land
parcels on which a public agency or qualified land trust has placed a conservation easement in cooperation
with the landowner. The dataset contains no information about ownership or status of the mineral estate.
For questions about the dataset or to report errors, please contact the Montana Natural Heritage Program at
(406) 444-5363 or mtnhp@mt.gov. You can download various components of the Land Management
Database and view associated metadata at the Montana State Library’s GIS Data List at the following links:

Introduction to Invasive and Pest Species
Within the report area you have requested, separate summaries are provided for: Aquatic Invasive Species,
Noxious Weeds, Agricultural Pests, Forest Pests, and Biocontrol species that have been documented or
potentially occur there based on the predicted suitability of habitat. Definitions for each of these invasive and
pest species categories can be found on our Species Status Codes page.
Each of these summaries provides the following information when present for a species: (1) the number of
observations of each species; (2) the geographic range polygons for each species, if developed, that the report
area overlaps; (3) predicted relative habitat suitability classes that are present if a predicted suitable habitat
model has been created; (4) the percent of the report area that is mapped as commonly associated or
occasionally associated habitat as listed for each species in the Montana Field Guide; and (5) links to species
accounts in the Montana Field Guide. Details on each of these information categories are included under
relevant section headers under the Introduction to Native Species above or are defined on our Species Status
Codes page. In presenting this information, the Montana Natural Heritage Program (MTNHP) is working towards
assisting the user with rapidly determining what invasive and pest species have been documented and what
species are potentially present in the report area. We remind users that this information is likely incomplete as
surveys to document introduced species are lacking in many areas of the state, information on introduced
species has only been tracked relatively recently, the MTNHP’s staff and resources are limited, and information is
constantly being added and updated in our databases. Thus, field verification by professional biologists of the
absence or presence of species will always be an important obligation of users of our data.
If you are aware of observation or survey datasets for invasive or pest species that the MTNHP is missing, please
report them to the Program Coordinator bmaxell@mt.gov Program Botanist apipp@mt.gov or Senior Zoologist
dbachen@mt.gov If you have animal or plant observations that you would like to contribute, you can also
submit them via Excel spreadsheets, geodatabases, iNaturalist, or a Survey123 form. Various methods of data
submission are reviewed in this playlist of videos:

RE: Laurel Meadows Subdivision
Dear Ms. Pearcy,
Montana Fish, Wildlife & Parks (FWP) appreciates the opportunity to comment on the Laurel Meadows
Subdivision.
An important project goal should be ensuring the completed subdivision poses no direct or persistent
environmental threat to Baxter Creek or the existing wetlands on the proposed development site. FWP
anticipates that your construction plans will include actions to reduce or mitigate sediment delivery, and
to prevent discharges of petroleum products or other harmful substances into streams or lands capable
of delivering these substances to nearby waterways. FWP recommends that stormwater management
systems in the development do not convey runoff directly into nearby streams without first having the
opportunity for groundwater filtration to occur.
Per FWP’s subdivision guidelines, FWP recommends a minimum stream setback of 200 feet. This
includes 150 feet of vegetation buffer plus an additional 50 feet of building setback along Baxter Creek.
Therefore, FWP recommends not only a building setback, but also maintaining an intact riparian zone
free of disturbance (e.g., trails associated infrastructure) along any streams to help protect the integrity
of surrounding streams and downstream habitats. Stream setbacks also provide the opportunity to
restore and maintain functioning riparian areas, which also help to reduce water temperatures of
surrounding aquatic habitats. FWP also recommends a minimum of 100 feet of vegetated buffer plus 30
additional feet of building setback from the existing and proposed mitigation wetlands on site.
Any proposed development that may physically alter or modify the beds or banks of the adjacent stream
(e.g., horizontal directional drilling, trails, riparian vegetation removal) is subject to approval and
permitting by the local conservation district under Section 75-7-101 (The Natural Streambed and Land
Preservation Act of 1975; “310 Law”).
