National Wildlife Refuges (NWRs) along the East Coast of the United States protect habitat for a host of wildlife species, while also offering storm surge protection, improving water quality, supporting nurseries for commercially important fish and shellfish, and providing recreation opportunities for coastal communities. Yet in the last century, coastal ecosystems in the eastern U.S. have been severely altered by human development activities as well as sea-level rise and more frequent extreme events related to climate change. These influences threaten the ability of NWRs to protect our nation’s natural resources and to sustain their many beneficial services. Through this project, researchers are collaborating with...

In the Southeast, where rapid human development is increasingly dividing natural areas, habitat fragmentation and loss threaten the health and even genetic viability of wildlife populations, and interrupt migration routes. Climate change is projected to exacerbate fragmentation by further disrupting landscapes. To make matters worse, it is also expected to shift the range of many species, forcing animals capable of adapting by moving to expand into new areas to find more suitable temperatures and adequate food supplies – a challenge made difficult, if not impossible, by disconnected landscapes. Maintaining connectivity between habitats is a key strategy for conserving wildlife populations into the future, and sound...

The Southeastern United States spans a broad range of physiographic settings and maintains exceptionally high levels of faunal diversity. Unfortunately, many of these ecosystems are increasingly under threat due to rapid human development, and management agencies are increasingly aware of the potential effects that climate change will have on these ecosystems. Natural resource managers and conservation planners can be effective at preserving ecosystems in the face of these stressors only if they can adapt current conservation efforts to increase the overall resilience of the system. Climate change, in particular, challenges many of the basic assumptions used by conservation planners and managers. Previous conservation...
Coastal ecosystems in the eastern U.S. have been severely altered by local processes associated with human development, including drainage of coastal wetlands, hydrologic alterations affecting sediment supply, and land-use change, and by global-scale ecological changes including sea-level rise and other effects associated with climate change. Together, these forces are degrading the capacity of ecological and social systems to respond to disturbance. The goal of this project was to foster active engagement with stakeholders; develop a comprehensive problem definition that expressed local values, knowledge, and perceptions; and encourage building of effective networks and trust across organizations and individuals...
Abstract (from ScienceDirect): Habitat connectivity is essential for maintaining populations of wildlife species, especially as climate changes. Knowledge about the fate of existing habitat networks in a changing climate and in light of land-use change is critical for determining which types of conservation actions must be taken to maintain those networks. However, information is lacking about how multiple focal species that use similar habitats overlap in the degree and geographic patterns of threats to linkages among currently suitable habitat patches. We sought to address that gap. We assessed climate change threat to existing linkages in the southeastern United States for three wildlife species that use similar...

The southeastern U.S. contains a unique diversity of ecosystems that provide important benefits, including habitat for rare wildlife and plants, improved water quality, and recreation opportunities. Understanding how climate change will affect these ecosystems is vital for knowing how best to protect them and the services they supply. The goal of this project was to assess the climate change vulnerability of 12 key ecosystems in the southeastern U.S. and Caribbean, ranging from Caribbean coastal mangrove to Nashville Basin limestone glade and woodland. Scientists used the existing scientific literature and geospatial analysis to determine each ecosystem’s sensitivity to changes in climate, its exposure level to...
