Abstract

Environmental factors were related to forest regeneration on clearcut and partially cut areas managed by the Bureau of Land Management in the Hungry-Pickett area northwest of Grants Pass, Oregon. The multiple regression equations developed for this study can be used to compare the relative difficulty of regenerating forested sites within the study area. The equations show that difficulty of regenerating clearcuttings increases with increasing solar radiation, temperature, rock cover, and depth of the soil A horizon. Difficulty of regenerating partial cuts increases with surface gravel cover and is related to slope, aspect, and vegetation.
