Frequent, low-intensity wildfires were once widespread across the Southeast US, which led to a reduction in unchecked vegetation growth that provided fuel for high-intensity fires. Both intentional and unintentional fire suppression and land-use changes have reduced many of these wildfires and the fire-adapted habitats in the region over time. This loss of frequent low-intensity wildfires on the landscape also increases the severity of wildfires due to fuel buildup and the encroachment of woody species. The remaining habitats and their native species (many of which are of conservation concern) are now almost completely dependent on prescribed burns for their persistence and survival. Successful application of fire...

The objective of this project is to map the supply of ecosystem services (where natural ecosystems have the capacity to provide a certain product or service that could be of use to people), use of those services (where people or other entities that use the product or service exist), and the condition of ecosystems providing these services over time. The resulting datasets were used to generate metrics for pilot ecosystem accounts for the southeast – part of natural capital accounts that assess ecosystems’ contributions to the economy in order to help governments better understand their reliance on natural systems and manage natural resources to ensure their benefits are sustained into the future. These data were...

The Southeastern U.S. spans broad ranges of physiographic settings and contains a wide variety of aquatic systems that provide habitat for hundreds of endemic aquatic species that pose interesting challenges and opportunities for managers of aquatic resources, particularly in the face of climate change. For example, the Southeast contains the southernmost populations of the eastern brook trout and other cold-water dependent species. Climate change is predicted to increase temperatures in the South and is likely to have a substantial effect on extant populations of cold-water biota. Thus, aquatic managers are tasked with developing strategies for preserving cold-water dependent biota, such as eastern brook trout,...

Coastal wetlands and the many beneficial services they provide (e.g., purifying water, buffering storm surge, providing habitat) are changing and disappearing as a result of sea-level rise brought about by climate change. Scientists have developed a wealth of information and resources to predict and aid decision-making related to sea-level rise. However, while some of these resources are easily accessible by coastal managers, many others require more expert knowledge to understand or utilize. The goal of this project was to collate science and models pertaining to the effects of sea-level on coastal wetlands into a format that would be accessible and useful to resource managers. Researchers conducted training sessions...

Assessing the impact of flow alteration on aquatic ecosystems has been identified as a critical area of research nationally and in the Southeast U.S. This project aimed to address the Ecohydrology Priority Science Need of the SE CSC FY2012 Annual Science Work Plan by developing an inventory and evaluation of current efforts and knowledge gaps in hydrological modeling for flow-­‐ecology science in global change impact studies across the Southeast. To accomplish this goal, we completed a thorough synthesis and evaluation of hydrologic modeling efforts in the Southeast region (including all states of the Southeastern Association of Fish and Wildlife Agencies (SEAFWA) including Alabama, Arkansas, Florida, Georgia, Kentucky,...

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 northern Gulf of Mexico, mangrove forests have been expanding their northern range limits in parts of Texas, Louisiana, and north Florida since 1989. In response to warming winter temperatures, mangroves, which are dominant in warmer climates, are expected to continue migrating northward at the expense of salt marshes, which fare better in cooler climates. The ecological implications and timing of mangrove expansion is not well understood, and coastal wetland managers need information and tools that will enable them to identify and forecast the ecological impacts of this shift from salt marsh to mangrove-dominated coastal ecosystems. To address this need, researchers will host workshops and leverage existing...

Climate change is expected to worsen the harmful effects of invasive species on native wildlife. This presents a growing conservation challenge for invasive species managers in the southeastern United States where thousands of invasive species exist. While many of these invasive species currently have relatively small ranges in the southeastern U.S., climate change may allow them to expand into new regions. To effectively plan and respond to the redistribution of invasive species, it is crucial to coordinate existing information and identify future information needs across regional boundaries. The ultimate goal of this project is to improve invasive species management in the face of climate change by establishing...

Coastal ecosystems are uniquely vulnerable to changes in the quantity and quality of freshwater discharge. With a warming climate, changes in freshwater discharge into estuaries will interact with rising sea levels. Coastal natural resource managers need guidance on the potential impacts and vulnerabilities to better manage the risks to aquatic species and habitats and to mitigate species decline or collapse resulting from changes in freshwater availability. This project will inform resource managers on the development of management plans that protect coastal ecosystems and species while accounting for changes in freshwater availability under climate uncertainty. To achieve this, the proposed project has three objectives....

Climate and land use change will strongly affect tropical island ecosystems and trust species (like migratory birds and threatened and endangered species). The risks of significant negative impacts are likely to be higher in these island systems than in many temperate regions of the world because of the limited size of their land masses, high numbers of species that only exist in narrowly defined regions, and expectations that tropical environments will experience greater changes in temperature. Tropical island communities are faced with making important decisions related to adaptation that could impact the health of important natural resources and ecosystems. However, a lack of scientific guidance and information...

Coastal marshes are vital habitats that protect and support our coastal communities and economies by providing protection from storm surge, filtering pollutants, and providing recreational opportunities. Rising sea levels threaten marshes and jeopardize the benefits they provide to human communities and ecosystems. To preserve these benefits, coastal resource managers need to understand how marshes will change in the short- and long-term in response to rising sea levels. Scientific models provide resource managers with an effective way to visualize and understand these changes, but the numerous choices of marsh models currently available can be overwhelming to coastal managers. The similarities and differences...

While 21st century temperatures are projected to increase in Puerto Rico and the broader U.S. Caribbean (whose geography is contained within the Caribbean Landscape Conservation Cooperative, or CLCC), the low variability and already high annual average temperatures suggest that the largest climate-related impact on ecosystems and water resources is more likely to be through changes in the timing, pattern, and availability of moisture. The development of adaptation strategies that respond to anthropogenic climate change for the CLCC, and particularly for Puerto Rico, is currently hindered by the lack of local-scale climate scenarios that resolve the complex topographical and meso-scale climate features that will...

The Global Change Graduate Fellows Program is designed to train the next generation of global change scientists by providing financial, scientific, and professional development support for graduate students who are interested in multi-disciplinary research. They come together across disciplines to discover, collaborate, and share their knowledge with diverse stakeholders. Additionally, students need to be dedicated to making the science related to climate change better, where better means more true, of a greater impact, or, as our land grant mission dictates, more ethical and just. This program is sponsored by the USGS Southeast Climate Adaptation Science Center and NC State University. Applicants must be an NC...

Coral reefs are some of the most biologically rich and economically valuable ecosystems in the world. They provide food, fishing, and recreation opportunities for millions of people, protect coastlines from storms, and shelter thousands of plant and animal species. However, climate change is contributing to the degradation of coral reefs in two significant ways: warming temperature and increasing acidification of ocean waters. Scientists are actively working to gather more specific information about how these factors will impact coral reef ecosystems. The purpose of this study was to identify differences in climate vulnerability among three important reef-building coral species in the Florida Keys. Researchers...

This project generated a series of freely available datasets that provide projections of climate change at appropriate spatial scales that can directly address specific management questions. These climate change projections are the result of “downscaling” output from global climate models (GCMs) that formed the basis of many conclusions in the Intergovernmental Panel on Climate Change (IPCC) Assessment Report 5 (AR5). The datasets include projections of climate variables in addition to daily temperature and precipitation such as surface winds, humidity, and solar radiation that are needed in hydrologic and ecological modeling. Two products, one at a 4-km resolution and the other at a 6-km resolution, covering the...

Amphibians in the US Caribbean, like the well-known coquí frog, are particularly vulnerable to human-caused climate change. Coquí frogs are represented by 17 species across Puerto Rico and US Virgin Islands and include several mountainous and coastal species that are threatened by extreme heat and drying, loss of coastal freshwater marshes through saltwater intrusion, or both. Over the past decade, the Southeast Climate Adaptation Science Center has invested in several scientific investigations to understand how global climate change is likely to affect the local climate of the US Caribbean and how sensitive different coquí species are to changes in local climate and habitat conditions in Puerto Rico. This project...

Climate change doesn’t just threaten our natural resources—it threatens our cultural resources, too. Cultural resources represent evidence of past human activity, such as archeological sites, or are of significance to a group of people traditionally associated with the resource, such as Native American ceremonial sites. Climate change is challenging the long-term persistence of many cultural resources. For example, those located in coastal areas, such as historic lighthouses, are threatened by sea-level rise, shoreline erosion, and more frequent severe storm events. While climate change challenges managers of both natural and cultural resources to make decisions in the face of uncertainty, far less work has been...

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...

Arguably the most direct, intense, and long-lasting modification that humans can make to a landscape is converting rural lands to urbanized areas. As human populations grow, the demand for urbanized areas will increase, and scientists can help natural resource managers plan for these changes by creating models that predict potential patterns of future urbanization. The Southeast U.S. is experiencing particularly rapid population growth, as a favorable winter climate has drawn millions to the region from other areas of the country over the past several decades. However, the Southeast is also at risk from the effects of climate change, particularly along its vast coastline, where over a quarter of the region’s population...

The pine rockland ecosystem is found only in south Florida and the Bahamas and provides important habitat for numerous rare and endemic plants and animals. These include 18 species that are already federally listed as threatened or endangered and four other species petitioned for listing that are scheduled for development of Species Status Assessments (SSAs). Today, south Florida’s pine rockland ecosystem represents less than 3 percent of its original extent. Threats such as saltwater intrusion from hurricanes and sea-level rise pose the greatest risk to the longevity of this ecosystem. For the U.S. Fish and Wildlife Service to make decisions about the potential listing of a species, they must be able to forecast...
