Location and Boundaries. The SKCP site and location begins at the headwaters of the Stillwater River in the Beartooth Mountains, including the tributaries, to the confluence with the Yellowstone River in Columbus, MT. The Stillwater River, which is approximately 113 kilometers (KM) long, rises in the Absarka-Beartooth Wilderness near the state line with Wyoming and flows northeast joining the Yellowstone River in Columbus, MT. The project covers the gravel bars and bank sections along the Stillwater River. (See Attachment 5 & 6).
B. Identify Ownership. There are multiple partners involved in the SKCP. These include: United States Forest Service (USFS), Natural Resources Conservation Service (NRCS), MT Fish, Wildlife, & Parks (MFWP), Stillwater …show more content…

Type of Ecosystem Being Restored and Site Conditions.. Spotted knapweed prefer habitats that consist of gravel/sandy soils, full sun, arid conditions in course soil, disturbed areas, and is tolerant to nutrient poor soils (Montana Weed Control Association (MTWEED), n.d.). The SKCP broke the river down into three sections, all have the same spotted knapweed concerns and goals, but have slightly different soil ecosystems. The first section starts at the headwaters and runs to Nye, MT (See Attachment 6) about river mile 35; this stretch contains faster moving stretches of rapids, but also areas that are very slow moving and slough. The higher river banks in the faster moving areas have rockier soil, and more drastic soil erosion caused by spotted knapweed. The slow areas and sloughs, like near Lake Sioux Charley (See Attachment 7), the largest moving slough, have moist, less rocky soil, and not as conducive growing environment for spotted knapweed. This area is primarily back country, already designated trails, and is deeply wooded in some areas, but is the least of the SKCP concern. The second section runs from Nye, MT to the Rosebud River, about river mile 12. The calmer, clearer water, with more gradual river banks, significantly more arid gravel bars, open sunny landscape, are all prime growing areas for spotted knapweed and the highest area of concern. It is also considered outstanding fly fishing waters, which creates more foot traffic on the river banks, creating more disturbed areas. The last section, runs from Rosebud River to the Yellowstone River, river mile 0. This section has significantly more rapids (famous area for whitewater rafting) and higher river banks, with the largest amount of private property along the river. The soil in this section is rocky and has primarily open sunny landscape, both are great growing environment for spotted knapweed. This area also receives the water from the Rosebud River, creating a larger amount of
