Assessment of goshawk nest area habitat using stand density index-Abstract
Robert J Lillieholm, James N Long, and Susan PatlaThe manipulation of stand density to create a specified stand structure in the future represents a powerful tool in wildlife habitat management. Controlling stand density, and ultimately stand structure, through initial tree spacing and/or subsequent thinning is critical achieving many specific stand management objectives. Indices of relative stand density, based on average tree size (e.g., mean weight, volume, height, or diameter) and stand density (e.g., trees per hectare) are useful in characterizing current and future stand structure. This paper describes Reineke's stand density index (SDI), and demonstrates its application to the management of northern goshawk (Accipiter gentilis) nest area habitat.
