Buffalo Creek Native Fish Restoration Environmental Assessment

The National Park Service (NPS) is initiating this Environmental Assessment (EA) to facilitate the removal of nonnative rainbow (Oncorhynchus mykiss) and hybridized trout from the Buffalo Creek drainage in Yellowstone National Park (Park) and the Custer Gallatin National Forest using the fish toxicant rotenone. Following the removal of nonnative and hybridized trout, native Yellowstone cutthroat trout (Oncorhynchus clarkii bouvieri) would be translocated into the Buffalo Creek drainage. The NPS previously approved this action for the portion of Buffalo Creek inside Park boundaries under the 2010 Native Fish Conservation Plan and EA (2010 Plan). In 2022, the U.S. Forest Service (USFS) and Montana Fish, Wildlife and Parks (MTFWP) proposed similar conservation measures for native Yellowstone cutthroat trout upstream of the park on lands administered by the USFS. Pursuant to 43 CFR 46.135 the NPS incorporates by reference the NPS 2010 Plan and the USFS & MTFWP Buffalo Creek Yellowstone Cutthroat Trout Conservation Project EA (USFS Plan), and is providing this EA to provide site-specific impact analysis on Park resources that may be affected as a result of the USFS Plan.
