Most of the economic opportunities to 
increase net annual timber growth in the 
South are on the other private ownerships. 
This primarily reflects the large acreages of 
timberland in those ownerships and less- 
intensive management practices. 
try ownerships, with the remainder—0.3 billion cubic 
feet—on the public ownerships. 
The distribution of the economic opportunities by ownership 
in both regions and in most States is much the same as that 
for the South. In most States, around three-quarters of the 
opportunities are on the other private ownerships, but there 
are some exceptions. In Tennessee, 84 percent of the oppor- 
tunities are on the other private ownerships; in Arkansas, 54 
percent. As in the South, there are opportunities to increase 
net annual growth on all ownerships in every Southern State. 
Nearly half of the economic opportunities to increase net 
annual growth, 1.5 billion cubic feet, consists of regenera- 
tion of cutover and nonstocked sites (fig. 5.7). About half 
of the regeneration opportunities are on cutover sites in the 
upland hardwood management type. There are also oppor- 
tunities on the mixed pine—hardwood management type (248 
million cubic feet) and the natural pine type (202 million 
cubic feet). On the relatively small acreages of nonstocked 
land, there are opportunities to increase net annual timber 
growth by 154 million cubic feet. Regeneration opportunities 
on pine plantations are only 24 million cubic feet, an 
indication of the high success rate of planting. Three-quarters 
of the opportunities for regeneration are on the other private 
ownerships. Nearly all of the rest are on the forest industry 
ownerships. 
After regeneration, the next largest treatment opportunity 
is harvest and regeneration of existing stands (819 million 
cubic feet). Most of this opportunity is harvest of mature 
stands, although salvage of stands damaged by fire, insects, 
disease, and other destructive agents is also important. A 
little over a third of the opportunities for harvest and regen- 
eration are in stands in the natural pine management type. 
Another third are in upland hardwood stands. The remainder 
are about equally divided between mixed pine—hardwood 
and bottomland hardwood stands. 
Two-thirds of the harvest opportunities are on other private 
lands and another fifth are on forest industry holdings. Be- 
cause of the policy of growing timber on longer rotations, 
there is also a substantial potential to increase net annual 
growth through harvest and regeneration on national forest 
holdings. 
The third largest treatment opportunity for increasing net 
annual timber growth is stocking control in adequately 
stocked stands that also have inhibiting vegetation. Imple- 
menting these treatment opportunities would increase net 
annual growth by 559 million cubic feet a year. Most of 
this potential, some 279 million cubic feet, is in upland 
hardwood stands, although there are also large potentials 
in the mixed pine—hardwood and natural pine management 
types. As with other treatment opportunities, most of those 
for stocking control—three—quarters of the total—are on the 
other private ownerships.
