Abstract
The 1990 forest inventory of North-Central Alabama revealed the following:Timberland area is 4,346.0 thousand acres, a decrease of 4 percentThe area of hardwood stands decreased by 5 percent and the area of oak-pine stands increased by 14 percentThe area of pine stands decreased despite an increase in the area of planted pine stands.Live-tree inventory volume totals 4.6 million cubic feet and was unchanged. A 22-percent increase in hardwood inventory volume was offset by an 18-percent decrease in softwood volume.Average net growth of live trees decreased by 3 percent. The net growth of hardwoods increased by 41 percent. The net growth of softwoods decreased by 28 percent.The removals of live trees increased by 10 percent. Both hardwood and softwood removals increased, by 8 and 11 percent respectively.The growth-to-removals relationship worsened since the previous inventory period due to severe overcutting of softwoods. For hardwoods and softwoods combined, removals are now equal to growth.The current growth-to-removals ratio for hardwoods is 2.0:1.0, an improvement since the previous period. The growth-to-removals ratio for softwoods is 0.7:1.0, compared to 1.0:1.0 for the previous period.
