The objectives of this study are to: 1) develop habitat suitability models for selected animal and plant species, 2) develop "coarse filter" habitat and landscape scale models, 3) develop approaches for modeling rare and poorly known species, and 4) conduct viability analyses for selected species or species groups. This study is important because it provides species and ecosystem level response models that operate at the scale of the landscape simulator and allow us to evaluate how forest policies affect different measures of biological diversity.

Habitat suitability models will be developed for over 30 species of selected animals and plants. The models will be developed in collaboration with Dave Vesely of the Umpqua Land Exchange Project and other collaborators who are experts in different taxa. Species will be selected based on their sensitivity and at-risk status and for their representation of different types of ecosystems (e.g. early vs late successional). Habitat suitability models will be developed based on literature review, screened through a sensitivity analysis procedure, and verified with empirical data available to the CLAMS project. Coarse filter models will likewise be developed from the literature and data available to CLAMS. Approaches for modeling rare and poorly known species will be developed in collaboration with a team of experts specializing in fungi, lichens, amphibians, and plants.. Viability analysis for selected species will be conducted through collaboration with Nathan Schumaker of the EPA using his Patch Model or variates thereof.
