Determining Differences in the Spatial Distribution of Forest Structure on the Kaibab Plateau: Implications for forest management and the northern goshawk
The Kaibab Plateau, in North Central Arizona, has undergone extensive change in the last 100 years due to land management practices such as logging, road building, and fire suppression. The northern goshawk (Accipiter gentilis) has been a center of controversy, due to the potential effects of silvic...
