Maps of forest species-climate profiles were developed to help predict how forests, plant communities, and species may change on the landscape in response to climate change. Each species map depicts a ‘viability score’, which is an index on the interval zero to one that indicates how consistent the climate at a location is with the contemporary occurrence of a species. A low score at a given point in time or space indicates that the species does not occur (or very rarely occurs) in climates like those depicted at that location.
These maps provide information on where suitable future climate may be located for specific tree species under different climate scenarios.
U.S. forests play a large role in offsetting carbon emissions, about 20 % of the U.S. fossil fuel carbon output. If a forest replaces itself after a disturbance like fire, then there is no long-term loss of carbon.
