Abstract:

This document summarizes the findings on the main stem of the upper Snake River and its tributaries. The survey area includes the main Snake River and lower reaches of its major tributaries from the confluence with the Henrys Fork downstream to Milner. Tributaries surveyed include the Arbon, Portneuf, Rockland, and Curlew valleys. Assessment of the quality and condition of plant communities and the occurrence of rare plant and animal species allowed us to categorize sixteen wetland sites based on conservation intent. The surveys were used to populate the Site Basic Record, Element Occurrence Record, and Community Characterization Abstract databases of the Biological and Conservation Data System. Database summaries are provided and include information on the biological significance of the surveyed wetland sites, abstracts for selected plant associations, and summaries of plant and animal species of special concern. Land managers can apply the process presented here to categorize wetlands, which were not surveyed.
