CURRENT GROWTH 1951-60 



Current annual net gro^vth is lo-\\er than in most 

 other forest regions of the United States. MortaHty 

 from suppression, wind, fires, insects, and diseases 

 ahiiost equals net growth. Mortality could be 

 reduced by improved forest management.

LLOWABLE GUT 



DRAIN 1948 



Annual drain (1948) on standing timber was not too 

 great. Ho^vever, it consisted too largely of soft- 

 woods, was concentrated too much in accessible 

 areas, sometimes ^vas accomplished by destructive 

 logging practices. 



Litjuidation of accessible timber has closed many 

 large sawmills in recent years — threatens many 

 others.
