Specifications include, but are not limited to: The Department of Wildlife is administering this contract to implement aquatic habitat restoration actions to restore and increase available habitat for the White River Spinedace at Sunnyside Creek at Department of Wildlife’s Kirch Wildlife Management Area, Nye County, Nevada. The White River Spinedace is endemic to Nevada and is listed as endangered by Nevada and the US Fish and Wildlife Service. The species relies on springs (Flag Springs complex) and their associated outflows for habitat (Sunnyside Creek). An old culvert exists on lower Sunnyside Creek and acts as a movement barrier to White River spinedace, which disrupts natural movement corridors and creates a population sink. Thus, restoration of Sunnyside Creek by removing the old culvert structure is needed.
