A stand density management diagram for Norway spruce plantations in central New YorkThis article is part of a larger document. View the larger document here.
Norway spruce (Picea abies (L.) Karst.) is an economically important species in the State of New York. It has been widely planted, especially in the 1930’s, and currently occupies about 100,000 acres of forest land in New York (46 percent sawtimber, 36 percent poletimber, and 18 percent sapling). Many of these plantations have already received thinning treatments over years. However, there is little information or few management tools available to guide forest managers in deciding when to start thinning and in selecting appropriate thinning intensities. The objective of this study was to construct a stand density management diagram for the Norway spruce stands in central New York.
