BLM REA NGB 2011 Bull Trout Fish Barriers

Barriers to upstream fish movement (either long-term geologic, natural short-term, or anthropogenic barriers) will be used to assess whether individual stream segments are currently occupied by bull trout, for assessing risk of genetic introgression or disease to existing bull trout populations, or whether existing subpopulations are connected with other subpopulations. Only those barriers that are believed to have a significant influence bull trout distribution or population integrity will be identified.
