The gopher tortoise (Gopherus polyphemus) is a familiar species across the southeastern Coastal Plain, but its population has declined significantly over the decades. One reason is that much of its primary habitat, sparse stands of mature pine, has been replaced by development or agriculture. Another is that periodic ground fires, which are important for providing needed forage for the tortoise, have been largely suppressed on the landscape. The gopher tortoise is a “keystone” species, meaning that its disappearance from the landscape would jeopardize the existence of many other species that make use of its underground burrows. Besides tortoise habitat, the uplands of the Coastal Plain contain isolated seasonal...

Grasslands are plant communities that have few or no trees, or have open canopies that allow for the development of a grassy groundcover. Grasslands in the southeastern U.S. support rare plant and animal species and in some cases qualify as global or regional hotspots of biodiversity. Yet the Southeast’s grasslands have been reduced by approximately 90% since European settlement, as the result of agriculture, urbanization, and fire suppression. Today, climate change represents an additional stressor that may pose direct and indirect threats to grassland-related biodiversity. Additional knowledge is urgently needed to evaluate conservation options for species of conservation concern in southeastern U.S. grasslands,...

The U.S. Fish and Wildlife Service and the Puerto Rico Department of Natural and Environmental Resources need to develop a plan of action to help the recovery of two endangered species in the genus Eleutherodactylus (commonly known as “coqui”), while also reducing the risk that 14 other coqui species would be added to the Endangered Species list. Prior work by these researchers has identified factors influencing life history for three representative species (E. wightmanae, E. britonni, and E. antillensis) including where species occur, their abundance, and key drivers of reproduction, all of which are driven by climate and land use change. For this next research stage, this project will: (1) characterize the ability...

We routinely encounter uncertainty when we make decisions – from picking a new morning coffee to choosing where to live. Even decisions that are supported by science contain some level of remaining uncertainty. In the context of conservation and wildlife management, the potential for uncertainty to influence decisions is perhaps most obvious when we think about predicting how actions (or non-actions) will have lasting impacts into the future. Our abilities to precisely predict future climatic and ecological conditions and determine the exact consequences of our actions are, and will remain, limited. Conservation practitioners and land and wildlife managers must navigate these challenges to make science-informed...

USGS researchers assessed how climate change can affect land cover and flow in river systems, examining a variety of resolutions for detecting and projecting the conditions of aquatic habitats and species.

The USGS and South Atlantic LCC worked with stakeholders and managers across the Southeast to identify and assess landscape-level strategies for conserving multiple species. These strategies incorporated predictions from downscaled climate models, sea level rise, and changes to aquatic and terrestrial habitats.

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...
