1
The importance of nontimber values [of forests] is dramatized in the provocative assertion that modern civilization could get along without wood, but not without forests. S.T. Dana
2
Forests & Wildlife What are the major forest types, how do they differ, and how do they relate to wildlife populations? How do forest structure and composition affect wildlife? What are the pros and cons of forest management practices for wildlife?
3
Forests & Wildlife How does forest ownership (private v. public) affect wildlife management? How have forests and their management changed? What are the major issues related to forests & wildlife? Who cares?
