Abstract
We examined the influence of logging and road construction on substrate and standing stocks of trout (Salvelinus and Salmo) in 28 stream reaches in the Medicine Bow National Forest, Wyoming. The extent to which roads crossed watercourses (culvert density) within a drainage and the proportion of the drainage that was logged were positively correlated to both the amount of fine substrate and embeddedness. Trout standing stocks had a negative relation with the density of culverts. Erosion of soil from road surfaces, ditches. and disturbed areas adjacent to roads that subsequently is deposited in stream channels seems to be an important mechanism by which logging has affected stream habitat.Keywords
