Keywords: Forest surveys, timber resources, statistics (forest), Alaska (south-central).A double sampling (two-phase) procedure was used to make estimates of area and volume. The first phase interpreted 26,745 aerial-photo sample plots. The plots on these photos were stratified by land class (timberland, other forest land, nonforest, and water). From the 26,745 photo points, a random sample was selected for visits on the ground. Tree measurements were made on these 361 plots in the second phase of the sampling to provide data for derived volume estimates. Area estimates were derived from proportional distribution of photo plots adjusted to ground i nf o rmat i o n .
