    Description

    The 1990 forest inventory of North-Central Alabama revealed the following:
    • Timberland area is 4,346.0 thousand acres, a decrease of 4 percent
    • The area of hardwood stands decreased by 5 percent and the area of oak-pine stands increased by 14 percent
    • The 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.
