Snow Breakage in Black and White Spruce in Interior Alaska Stands
Quantitative evidence now indicates the importance of snow and ice breakage to the development of white and black spruce stands in interior Alaska. During the winter of 1967-1968, 28 percent of the stems in a 160-year-old black spruce and 23 percent of the stems in a 178-year-old white spruce stand were broken as a result of snow and ice accumulation. The quantity of material deposited on the forest floor was about 11.2 and 13.3 metric tons per hectare in the black and white spruce, respectively. Data are also presented on the quantity of selected nutrients added to the forest floor by this breakage.
