Project Description

One of the main threats to steelhead recovery is the presence of non-native aquatic species that out-compete native species for limiting resources in the river, and prey on eggs and juvenile stages of native species. San Mateo Creek is inundated with non-native aquatic species including bass, crayfish, bluegill, bull frogs, black bullheads, green sunfish, and carp. Removal of non-natives, as well as public education and community interaction to identify sources of non-native introduction, will benefit trout and other sensitive species habitat enhancement efforts throughout these watersheds.
