The southeastern U.S. contains a unique diversity of ecosystems that provide important benefits, including habitat for wildlife and plants, water quality, and recreation opportunities. As climate changes, a better understanding of how our ecosystems will be affected is vital for identifying strategies to protect these ecosystems. We assessed climate change vulnerability for twelve ecosystems in the southeastern U.S. and Caribbean. We synthesized data and literature related to three components of vulnerability: climate sensitivity, climate change exposure, and adaptive capacity. We also summarized all information into a qualitative vulnerability rating for each ecosystem. Based on the available information, we identified...
In the Southeastern U.S., “insular ecosystems” may be particularly vulnerable to ecological effects from climate change. These insular ecosystems share a few key biogeographic characteristics: (1) occurrences that are spatially discrete, (2) relatively small geographic footprints, and (3) with steep ecological and environmental gradients at their boundaries. Examples include rock outcrop ecosystems (e.g. Piedmont granite outcrops, Appalachian high-elevation outcrops), grasslands (high-elevation balds, xeric limestone prairies), isolated wetlands (Carolina bays, karst depression wetlands) and riparian riverscour systems. Such insular ecosystems tend to support concentrations of endemic and disjunct species; thus...

Abstract (from esa): For decades, botanists have recognized that rare plants are clustered into ecological “islands”: small and isolated habitat patches produced by landscape features such as sinkholes and bedrock outcrops. Insular ecosystems often provide unusually stressful microhabitats for plant growth (due, for example, to their characteristically thin soils, high temperatures, extreme pH, or limited nutrients) to which rare species are specially adapted. Climate‐driven changes to these stressors may undermine the competitive advantage of stress‐adapted species, allowing them to be displaced by competitors, or may overwhelm their coping strategies altogether. Special features of insular ecosystems – such as...
