The State of the South Atlantic is a South Atlantic LCC publication designed to help us all understand our living landscapes—from hardwood forests and aquatic diversity in the Piedmont ecoregion to ships unloading freight near historic lighthouses along the shoreline. In addition to highlighting the area’s conservation successes and challenges, the State of the South Atlantic provides a report card for the current condition of our important resources. You can read about all the South Atlantic ecosystems, learn how they currently score in terms of ecological health, and read forecasts for the future. The scores are based on the measurement of key natural and cultural resource indicators, all detailed in the State...
This report summarizes the results of a three-year investigation of terrestrial habitat connectivity priorities for the South Atlantic Landscape Conservation Cooperative (South Atlantic LCC). Our primary objective was to generate results that could be used to drive fineā€scaled conservation planning to enhance habitat connectivity across the South Atlantic LCC. The project focused on seven target species, including large mammals (black bear, red wolf, Florida panther/eastern cougar) and a group of terrestrial reptiles (eastern diamondback rattlesnake, timber rattlesnake, pine snake, and box turtle). We used two different modeling approaches to identify areas with either high predicted flow of a given species (Circuitscape)...
We quantified trophic and reproductive functional diversity (SES FDis) of freshwater fish communities and related these measurements to environmental indicators to inform conservation planning actions as part of the South Atlantic Landscape Conservation Cooperative (SALCC). We estimated functional diversity at two different spatial scales (regional and local) using datasets of different sampling intensity and time duration. Our regional-scale analysis measures functional diversity across the SALCC at the sub-basin, or HUC8-scale, using occurrence data obtained from the MARIS and NAS databases. Our local-scale analysis is based on a systematic sampling program conducted by the South Carolina Department of Natural...

Three components of the scientific research included a literature review, a geospatial database, and ethnographic research. The literature review surveyed the professional, grey, and peer-reviewed literature on spatial conflicts in the marine environment. Summaries of the literature tracked how stakeholders resolved, mitigated, and addressed space use conflicts. A geospatial database was developed to include available GIS data and new GIS data produced by the study team. The ethnographic data collection occured by engaging individuals and small groups in one on one guided discussions. In addition, the study team convened larger group meetings to describe the study and to develop contacts for further research.
Sea level rise (SLR) and disturbances from increased storm activity are expected to diminish coastal habitats available for sea turtle, seabird, shorebird, and beach mouse nesting by removing habitat as well as inundating nests during critical incubation periods. The goal of our proposed research is to evaluate past nesting patterns of fourteen coastal nesting species and predict future effects of sea level rise on nesting beaches along the South Atlantic Bight. Maps of coastal vulnerability to SLR combined with historical data sets of long-term and spatially extensive nesting habitat will lead to models that enhance our understanding of the complex environmental changes occurring from global climate change and...
The Southeast Natural Resource Leaders Group has undertaken the Landscape Conservation and Restoration Pilot Project (LCRPP) to provide Federal leadership in natural resource protection that will accomplish three goals. The first goal is to develop a consistent approach to understanding the shared values of the natural resource agencies. These values are embedded within the funding objectives used to protect important natural, cultural, and social resources in the Southeast. The second goal is to develop shared tools that can assist local communities in protecting important landscapes from climate change and other potential risks. The third goal is to establish a common framework of accountability that provides...
The development of robust modelling techniques to derive inferences from large- scale migratory bird monitoring data at appropriate scales has direct relevance to their management. The Integrated Waterbird Management and Monitoring programme (IWMM) represents one of the few attempts to monitor migrating waterbirds across entire flyways using targeted local surveys. This dataset included 13,208,785 waterfowl (eight Anas species) counted during 28,000 surveys at nearly 1,000 locations across the eastern United States between autumn 2010 and spring 2013 and was used to evaluate potential predictors of waterfowl abundance at the wetland scale. Mixed-effects, log- linear models of local abundance were built for the Atlantic...

The southeastern United States is a recognized hotspot of biodiversity for a variety of aquatic taxa, including fish, amphibians, and mollusks. Unfortunately, the great diversity of the area is accompanied by a large proportion of species at risk of extinction. Gap analysis was employed to assess the representation of evolutionary hotspots in protected lands where an evolutionary hotspot was defined as an area with high evolutionary potential and measured by atypical patterns of genetic divergence, genetic diversity, and to a lesser extent genetic similarity across multiple terrestrial or aquatic taxa. A survey of the primary literature produced 16 terrestrial and 14 aquatic genetic datasets for estimation of genetic...

Landscape Conservation Cooperatives (LCCs) are public-private partnerships composed of states, tribes, federal agencies, non-governmental organizations, universities, international jurisdictions, and others working together to address landscape and seascape scale conservation issues. LCCs inform resource management decisions to address broad-scale stressors-including habitat fragmentation, genetic isolation, spread of invasive species, and water scarcity-all of which are magnified by a rapidly changing climate. For further information go to http://lccnetwork.org. The previous 2011 LCC Network Areas data is available at https://www.sciencebase.gov/catalog/item/52f2735ee4b0a6f0bd498c2f

Coastal Mean High Water (MHW) is contoured in intertidal zones open to oceans, behind barrier coasts in bays, lagoons, and estuaries, and sometimes where tidal currents reach upstream (landward) of the embayed foreshore water bodies. In the National Geospatial Program (NGP) surface water hydrography maintained in the Nation Hydrography Dataset (NHD) Flowline Network projects Mean High Water level (MHW) as the linear-referenced 1:24,000-scale resolution NHD Coastline (http://nhd.usgs.gov/). NHDCoastline Geomorphology and associated Risk line-event feature classes that rank the relative risk of horizontal erosion on a scale of 1 to 5 (least to most risk, respectively) have been developed using the Hydrography Event...
Invasive species are a global issue, and the southeastern United States is not immune to the problems they present. Therefore, various analyses using modeling and exploratory statistics were performed on the U.S. Geological Survey Nonindigenous Aquatic Species (NAS) Database with the primary objective of determining the most appropriate use of presence-only data as related to invasive species in the South Atlantic Landscape Conservation Cooperative (SALCC) region. A hierarchical model approach showed thata relatively small amount of high-quality data from planned surveys can be used to leverage the information in presence- only observations, having a broad spatial coverage and high biases of observer detection and...
Managers and scientists are working together in a new project to understand and optimally manage conservation lands along the Atlanta and Mississippi Flyways to support continental populations of waterbirds. It will advance the development of an integrated waterbird monitoring and management program to inform decision-makers and resource managers in an adaptive management context, resulting in improved resource contributions toward waterfowl, shorebirds, and long-legged waders. This project uses adaptive management and modeling tin an innovative way that incorporates their management expertise as well as new conservation planning and modeling tools. We are focusing on wetland-dependent migratory birds that use the...

Ecosystems of the southeastern United States face a large number of threats to their ecological integrity, including loss of habitat, climate change, exotic species invasion, and many more. NatureServe staff, in conjunction with the South Atlantic Landscape Conservation Cooperative (SALCC), have compiled this report in order to better understand how these threats impact ecosystems and the level of impact to these ecosystems, thereby addressing a key information need identified by the SALCC. We have organized the threats according to the first and second level threats classification of the Conservation Measures Partnership (Salafsky et al. 2008). The Conservation Measures Partnership maintains a standard nomenclature...
