Forest statistics for Central Tennessee counties - 1989

Abstract

The 1989 survey of the Central Unit of Tennessee revealed the following:Timberland now covers 2,416.3 thousand acres, an increase of 14 percent since 1980.Ninety-five percent of the unit’s timberland is privately owned.Cedar and mixed cedar-hardwood stands occupy 456.1 thousand acres of timberland.Oak-hickory forests account for 79 percent of the unit’s timberland.Area in sawtimber-sized stands increased by 250 thousand acres with most of the increase in oak-hickory forest types.The number of hardwood growing-stock trees fell 17 percent, while softwood numbers increased 26 percent.Hardwood growing-stock volume climbed 55 percent to 2,304.7 million cubic feet and softwood growing-stock volume climbed 74 percent to 138.1 million cubic feet.Softwood sawtimber volumes more than doubled and hardwood sawtimber volumes increased by two-thirds since 1980.Hardwood sawtimber quality declined since 1980.Net growth increased for both growing stock and sawtimber despite a doubling in mortality.Removals increased for both growing stock and sawtimber but were concentrated in the sawtimber portion of the inventory.Growth exceeds removals by roughly 3 to 1.
