Climate change is creating new challenges for biodiversity conservation. As temperatures, rainfall patterns, and sea levels change, distributions of plants and animals may shift geographically, altering their relationships with the environment and other species. As part of the response to climate change, the conservation community is starting to make decisions on longer time frames and with a focus on “adaptation” strategies to help species and habitats adjust. One of the first steps in adaptation planning is to conduct vulnerability assessments to identify which species or systems are likely to be most affected by climate change and why. Climate envelope models are an important tool used in vulnerability assessments to help resource managers understand how plants and animals may respond to a changing climate. Climate envelope models describe the climate where a species currently lives (its climate “envelope”), and then map the geographic shift of that envelope under climate change. Because we can’t know for certain how climate will change in the future, multiple climate change scenarios are used in these models. Our future work will incorporate habitat data and other kinds of information into the models to refine projections for future distributions of threatened and endangered species. Well-validated models can provide information for natural resource planning by identifying species most at risk from climate change and highlighting areas of potential future conflict between human activities and conservation priorities. The climate envelope modeling project is a partnership among the University of Florida, U.S. Fish and Wildlife Service, U.S. Geological Survey, and National Park Service.
