    Description

    A baseline assessment of forest resources in southeast Alaska was made by using a single-phase, unstratified, systematic-grid sample, with ground plots established at each grid intersection. Ratio-of-means estimators were used to develop population estimates. Forests cover an estimated 48 percent of the 22.9-million-acre southeast Alaska inventory unit. Dominant forest types are the western hemlock-Sitka spruce, mixed conifer, and western hemlock types. The timberland portion of productive forest land for all owners is estimated to be 4.1 million acres. Net volume on timberland was estimated at 21,040 million cubic feet. Estimated gross = growth of timberland forests exceeded estimated mortality by 55.8 million cubic feet. Field data collection was conducted from 1995 to 2000, and data compilation progressed through 2002.
