One- Fourth of Commercial Forest Area 

 Is Poorly Stocked or Nonstocked 



In addition to the 41 million acres of commercial 

 forest land with less than 10 percent stocking, 

 there are 73 million acres which are 10 to 40 per- 

 cent stocked. Thus a total of 26 percent of the 

 commercial forest lands, exclusive of old-growth 



stands, support less than 40 percent of full stock- 

 ing (table 19 and fig. 15). About 74 percent of 

 the commercial forest land is 40 percent or more 

 stocked. It is encouraging that nearly half of all 

 commercial forest land is in the well-stocked cate- 

 gory (70 percent or more) . In each section of the 

 country there is a larger acreage in the well- 

 stocked category than in any of tlie other classes.
