This handbook describes the standard inventory procedures for collecting fish habitat and salmonid fish species data for streams managed by the Northern (R1) and Intermountain (R4) Regions of the Forest Service, U.S. Department of Agriculture. The inventory procedures are designed to define and quantify the structure, pattern, and dimensions of fish habitat; describe salmonid species composition, distribution, and relative abundance; and facilitate the calculation of summary statistics for habitat descriptors.
