INT-GTR-300: Fish habitat conditions: using the Northern/Intermountain Regions' inventory procedures for detecting differences on two differently managed watersheds


Overton, C. Kerry; Radko, Michael A.; Nelson, Rodger L. 1993. Fish habitat conditions: using the Northern/Intermountain Regions' inventory procedures for detecting differences on two differently managed watersheds. Gen. Tech. Rep. INT-300. Ogden, UT: U.S. Department of Agriculture, Forest Service, Intermountain Research Station. 14 p.

Differences in fish habitat variables between two studied watersheds may be related to differences in land management. In using the R1/R4 Watershed-Scale Fish Habitat Inventory Process, for most habitat variables, evaluations of sample sizes of at least 30 habitat units were adequate. Guidelines will help land managers in determining sample sizes required to detect differences, under varying management, of such variables as channel morphology, substrate, large woody debris, and bank conditions.

Keywords: habitat variables, sampling frequency, logging effects, channel morphology, streams
