Climate Impacts

ForestA major goal of Resource Monitoring and Assessment (RMA) research is to identify how inventory and monitoring data can be used to understand the effects of climate on the forest and rangeland condition.

The Pacific Northwest RMA program collects and analyzes long-term data at multiple spatial scales, ideal for predicting tree distribution, growth, and mortality in relation to regional climate gradients and potential shifts in climate. The RMA scientists also assess climate impacts to understory plant and lichen communities.
