Description: Forest inventory data collected in 1987 fTom sample plots established on the Kenai Peninsula were analyzed to provide point-in-time estimates of the trend and current status of a spruce beetle infestation. Ground plots were categorized by stage of infestation. Estimates of numbers of live and dead white spruce trees, cubic-foot volume in those trees, and areal extent of infestation were developed and are presented for each stage of infestation.

Keywords: Forest surveys, timber resources (insect damage), statistics (forest), Alaska (Kenai Peninsula)
