Bull Run River (Oregon) [SEP] Flora and fauna
About 5 percent of the watershed consists of unvegetated water bodies or bare rock and a tiny fraction of meadow. More than 250 wildlife species, including peregrine falcon, bald eagle and northern spotted owl are thought to frequent the watershed. Migratory birds such as loons use the basin for feeding and nesting as they travel along the Pacific Flyway. Native fish species include chinook and coho salmon, steelhead, coastal cutthroat trout, Pacific lamprey, and rainbow trout, but since 1922 the headworks dam or its successor, Dam 2, have blocked anadromous fish passage to the upper river and its tributaries. Many amphibian and reptile species thrive near streams and ponds.
