    Description

    Area and volume statistics from the first intensive forest inventory of the upper Koyukuk River drainage, in north-central Alaska, are given. Observations are made on forest location, description, defect, regeneration, growth, and mortality. Commercial forests, although generally restricted to a narrow band along drainages, were found as far as 70 miles (113 kilometers) north of the Arctic Circle. Commercial forests occupy less than 5 percent of the 742,000-acre inventory area but, despite the northerly latitudes, support an average volume in excess of 1,100 cubic feet per acre (80 cubic meters per hectare).
