(4) Bottomland hardwoods (28).' The bottomland hardwood stands 

 include a great variety of hardwood species together with cypress. 

 In table 17 these have necessarily been grouped into the principal 

 genera. Figure 16 shows graphically the cubic-volume distribution 

 of the same stand. These data are based on an inventory of 10,000 

 acres in south-central Louisiana and are believed to be typical of 

 about 6 million acres in the type. 



TABLE 16. Number of trees, volume, and growth in average stocked stand of longleaf 

 and slash pine in Florida * 



1 Said to be typical of 20,000,000 acres in naval stores region. Much of the growth is never utilized for saw 

 timber, owing to use of trees for turpentining. 



2 The growth indicated is an approximation. The mortality was assumed to reduce gross volume growth 

 by 25 percent.
