The Center for Aquatic Nuisance Species will develop and implement weed removal and native vegetation restoration efforts with the assistance of local anglers and weed managers. The project will map riparian weed infestations along the Upper Yellowstone River. Noxious weeds are a serious ecological and economic problem and millions of dollars are spent each year to eradicate or control these invaders. Invasive weed infestations in riparian areas result in increased sediment transport, reduced groundwater storage, loss of overhead cover, increased water temperatures, and other serious ecological impacts. This project will improve riparian habitats on the Upper Yellowstone River by using anglers to conduct native vegetation restoration following weed control activities. Anglers will learn about the threats of weeds, map current weed distribution on nearly 200 miles of River and join the effort to reduce weed spread. Accurate GPS maps of weed infested areas of the Upper Yellowstone River will be created and used to develop integrated weed management plans for infested areas and implement the removal of invasive weeds and the restoration of native vegetation. While improvement of riparian health is a primary focus of this project, the project will also result in a cadre of trained individuals watching for invaders and will develop and strengthen relationships between recreationists and landowners. Project partners include Montana Trout Unlimited, Federation of Fly Fishers, Montana Walleyes Unlimited, Montana PikeMasters, Montana BASS Federation, Center for Invasive Plant Management, and Montana Fish, Wildlife & Parks.
