Rates of Tree Growth and Forest Succession in the Anchorage-Matanuska Valley Area
Results of vegatation study by U.S. Army Map Service in summer 1955 in the area 61 07-45 N. approx. 149-150 W, from sea level to tree line at 1,500-2,000 ft. Eight principal forest cover types were distinguished. Sixty-five test plots were laid out, in which trees were counted, diameters and heights...
