Site Index of Sitka Spruce Along the Pacific Coast Related to Latitude and Temperatures

Equations were developed which show that site index (100 years) of Sitka spruce along the North Pacific coast is highly correlated with latitude and mean annual growing degree days. Site decreases approximately 1 m per degree of latitude, averaging about 48 m in Lincoln County, Oregon, and 33 m in northern southeast Alaska. Farther north and west, Yakutat, Prince William Sound, and Kodiak average much lower in site than predicted by latitude or growing degree days. Sitka spruce will grow and reproduce in some areas of the naturally treeless Aleutian Islands but growth there is very slow. Forest Sci. 25:145-153.
