Logging, Infiltration Capacity, and Surface Erodibility in Western Oregon

Abstract

Infiltration capacity and erodibility were measured three to six years after portions of forested watersheds in western Oregon had been logged. Overall values on the logged portions did not differ significantly from values on unlogged portions. Areas that had been heavily disturbed--skid trails, cable log paths, and places where slash had been windrowed by tractors and then burned--had reduced infiltration capacity and increased surface erodibility but also had partially recovered to prelogging conditions.
