Economic Opportunities To Increase 
Net Annual Timber Growth, by State 
Economic opportunities to increase net annual growth ex- 
ist in every State in the South, but they are not equally dis- 
tributed (tables 5.6 and 5.7). No single reason can be given 
as the primary determinant of economic opportunities in the 
States. In some cases, stands are already in reasonably pro- 
ductive condition, and, therefore, the options to increase net 
annual growth through more intensive management are 
few. In other cases, markets are relatively weak, and this, 
too, may lead to a reduced number of economic 
opportunities. 
Detailed data similar to that in appendix tables 5.1—5.6 
on the economic opportunities for increasing net annual 
growth by ownership, forest management type, and treat- 
ment are available for each of the 12 Southern States. These
