Salmon Research: Beaver Dams, Fish Passage & Stream Ecology
There is some disagreement whether beaver positively or negatively affect salmon production. In some cases, beaver dams may present barriers to adult and juvenile salmon migration and in other situations beavers are introduced to improve salmon habitat. ARRI is proposing to conduct a literature review to investigate the positive and negative interactions between beaver and salmon. In addition to reviewing the literature, they will conduct interviews with local biologists. They will produce an annotated bibliography and summary report that describes how and when beaver damsn should be modified for fish passage.
Literature review is complete. One-page summary and more in-depth guidance document have been developed to inform users on how and when beaver dams should be modified for fish passage. Will present at Salmon Symposium in Fall 2018.
