INT-GTR-278: Assessment of COWFISH for predicting trout populations in grazed watersheds of the Intermountain West


Cantor, Craig R.; Platts, William S. 1991. Assessment of COWFISH for predicting trout populations in grazed watersheds of the Intermountain West. Gen. Tech. Rep. INT-GTR-278. Ogden, UT: U.S. Department of Agriculture, Forest Service, Intermountain Research Station. 28 p.

The COWFISH model, developed and applied in selected Montana streams, was tested on 14 streams in Idaho, Nevada, and Utah, where it proved to have little value for predicting numbers of trout in watersheds grazed by livestock. The model holds promise for estimating the health of stream channels and riparian complexes.

Keywords: fish habitat, livestock grazing, habitat suitability index, model testing
