OAK-CHESTNUT TYPE ON THE MONT ALTO STATE FOREST, PA. (33) 



In the stand represented by figure 22 and table 25 chestnut has 

 been killed out by the chestnut blight and' has been almost completely 

 replaced by other hardwood species. The stand has had excellent 

 care for a quarter century or more, with cuttings which removed 

 inferior trees and species. In this way its growing stock has been 

 built up far beyond what will ordinarily be found within privately 

 owned forests. During this building-up process large volumes of 

 timber have been harvested and efficient fire protection has been 

 provided at all times. Only through such procedure can private 

 owners obtain profitable returns from their holdings. The growing 

 stock limits suggested are averages applying to an entire compart- 

 ment where cuttings are made periodically.
