Russian olive and tamarisk are two invasive species that have established along the Green River. These two species are poor riparian plants and are outcompeting the native vegetation. Native vegetation is well suited to stabilize stream banks and capture sediment, thereby improving water quality. Currently the Wyoming Game and Fish Department has funded the Teton Science School to conduct an assessment from Fontenelle Dam to the southern end of Seedskadee National Wildlife Refuge (NWR), and the City of Green River is treating Russian olive and Tamarisk on their properties. There is a need to complete an assessment from the southern boundary of Seedskadee NWR to Flaming Gorge Reservoir, initiate control measures and provide plant materials. WLCI has agreements in place with the Bureau of Reclamation and Seedskadee NWR to control invasive species provide native plant materials. Funding is needed to provide control of invasive woody species and provide native vegetation to private landowners.
