Ferguson Road borders the property to the east with Fallon Street on the north and Resort Drive on the west. There are currently no structures on the property. Paved walking paths have been installed along the lengths of the property on the south(Huffine)and east(Ferguson). There is a ditch/creek with running water bisecting the property.A very small marsh or lake is located at the northwest corner.A dense stand of cottonwoods and willows line the waterway. Small trees are also located in the northwest corner near the lake.The balance of the property is treeless and covered with grasses and weeds. Property Weed Survey The subject property was surveyed in the fall of 2018. Weeds were found throughout the property but were most prevalent along the exterior margins, the creek/ditch and the west side from the ditch to Resort Street (see diagram below,weed concentrations highlighted). V! Ferguson Farm 2 31 Acre Proposed Subdmsion � 7 Y e 1l I a•.aaN.6er Lam...LL 191 - eee The non-highlighted interior of the property, which comprises approximately 10 of the 31 total acres, has only scattered weeds visible. It is apparent that soil disturbances due to the construction of surrounding roads, adjacent development, and the walking paths has resulted in invasive weeds around the perimeter of the property. A small stand of common tansy was found in the interior as well as numerous western salsify. While salsify is an invasive weed it is not currently listed on Montana's noxious weed list. Montana Noxious Weeds Noted in Survey The primary noxious weeds found on the property include Canadian Thistle, Spotted Knapweed, and Hoary Alyssum. Canadian Thistle is prominent along the creek and north and west borders of the property. Additional Canadian thistle was found along Ferguson and between Huffine and the south walking path. Spotted knapweed was prevalent along the west and north sides of the property and spread between the creek and Resort to the west. Hoary Alyssum was found along the south and west walkways and throughout the west end. A small patch of Common Tansy was noted in the interior of the property. Other Invasive Weeds The property also has Western Salsify, Flixweed, Kochia, mustards and some musk thistle. Weed Management Plan Due to the waterway and the small pond/marsh we would recommend an application of Dow Milestone for control of the thistle and knapweed near the creek, pond and trees. Dow Milestone can be applied up to waters edge and is less damaging to native forbs, shrubs and trees. For the balance of the property we recommend Dow Chaparral combined with an Amine 2,4D for improved control of the Common Tansy and Hoary Alyssum. Chaparral provides a broader range of control including plants in the mustard family and tougher weeds such as tansy and western salsify. Application method and timing. We recommend broadcast spraying the 21 acres containing the greatest concentration of weeds. Stands of thistle and knapweed near and among the trees will require hand spraying with Milestone. The balance of the interior property (10 acres) can likely be just spot sprayed for visible weeds. This application should be completed after May 15"' and before June 151h to maximize control of the early emerging weeds such as Hoary Alyssum while providing control of thistle, knapweed and tansy prior to bolting. Application rates Dow Milestone at 5 ounces per acre combined with a non-ionic surfactant at 1 pint per acre. Dow Chaparral at 3 ounces per acre combined with an amine 2,41) at 1 Qt per acre and a non- ionic surfactant Years 2 and 3 After the first year of application we would expect a significant reduction in the weeds. This will be dependent on the extent of the seed base,new soil disturbances and weather. A follow up application will likely be required on most of the areas with the highest concentration of weeds. By year 3 we would expect a spot spraying application will suffice to provide control of any residual weeds or new infestations. Cost Year 1 —20 acres broadcast @$75/acre=$1500,4 hours hand spraying and spot spraying tree-line, marsh/pond and interior 10 acres-$400—Total Year 1 =$1900. Year 2—Estimated broadcast and spot spraying=$1200 Year 3 —Estimated four hours spot spraying-$400. This plan was developed by Mark Nichols, owner 406 Weed Control LLC.
