Pole-timber Volume Increases 
In contrast to the 10-percent reduction in saw-timber 
volume since 1936, pole-timber volume has increased 
(table 8). Like saw-timber volume, 
the degree of change in pole timber varied widely in 
various parts of the State and among species. 
by 15 percent 
In the Piedmont, pole-timber volume increased 50 
percent. Both pine and hardwood pole timber decreased 
only slightly less than saw timber in the southern Coastal 
Plain; pine by 27 percent and hardwoods by 10 percent. 
hardwoods 5.0 to 12.9 inches. 
The change in pine pole-timber volume in the northern 
Coastal Plain was hardly significant, but hardwood 
species increased 19 percent. 
STANDS IN POOR CONDITION TO GROW TIMBER 
As a timber-producing plant, the forest falls far 
short of its potentialities; it has an unbalanced distri- 
bution of tree-size classes, individual stands are generally 
poorly stocked, and they contain a high proportion of 
cull and low-grade material.
