Abstract

In the interior Columbia River basin midscale ecological assessment, we mapped and characterized historical and current vegetation composition and structure of 337 randomly sampled subwatersheds (9500 ha average size) in 43 subbasins (404 000 ha average size). We compared landscape patterns, vegetation structure and composition, and landscape vulnerability to wildfires and 21 major forest insect and pathogen disturbances of historical and current forest vegetation coverages. We report on methods used to classify and map potential vegetation of individual patches of sampled subwatersheds at the plant level.
