Aspen and conifer heterogeneity effects on bird diversity in the northern Yellowstone ecosystem
—We addressed the following question: Do conifers within aspen stands (conifer invasion) increase bird species diversity in western landscapes? We tested the hypotheses that bird species diversity, measured as species richness or with the Shannon-Weiner diversity index, responds to aspen-conifer ratios (from 0% to 100% conifer) in a quadratic manner with a maximum occurring at an intermediate r...

متن کاملManagement of Westside Washington Conifer Stands Infected with Heterobasidion annosum
Timber stands in western Washington € are managed for many purposes. Such stands yield € commodity and noncommodity outputs, such as € recreation, wildlife, visual resources, or € watershed benefits, and often from the same € stands. Annosus root disease is widespread in € many mixed conifer stands within the western € hemlock, mountain hemlock, and Pacific silver fir € zones west of the Cascad...
متن کاملOptimal Stochastic Pine Stands Harvest Rotation Policies
A new Faustmann optimal rotation harvesting stands’ problem under Brown geometric price and Logistic and Gompertz wood stock, diffusions is presented. The optimal cut policies for the stochastic Faustmann model and the single harvest rotation or Vicksell model are evaluated in the case of a Chilean Radiata pine forest company. The company cut policy validates the Vicksell model, its optimal cut...
متن کاملVarying rotation lengths in northern production forests: Implications for habitats provided by retention and production trees
Because of the limited spatial extent and comprehensiveness of protected areas, an increasing emphasis is being placed on conserving habitats which promote biodiversity within production forest. For this reason, alternative silvicultural programs need to be evaluated with respect to their implications for forest biodiversity, especially if these programs are likely to be adopted. Here we simula...
