High-resolution elevation data provide a foundational layer needed to understand regional hydrology and ecology under contemporary and future-predicted conditions with accelerated sea-level rise. While the development of digital elevation models (DEMs) from light detection and ranging data has enhanced the ability to observe elevation in coastal zones, the elevation error can be substantial in densely vegetated coastal wetlands. In response, we developed a machine learning model to reduce vertical error in coastal wetlands for a 1-m DEM from 2018 that covered Nassau and Duval Counties, Florida. Error was reduced by using a random forest regression model within situ observations and predictor variables from optical...
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...
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 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...

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 https://www.fws.gov/science/catalog. The previous 2011 LCC Network Areas data is available at https://www.sciencebase.gov/catalog/item/52f2735ee4b0a6f0bd498c2f

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...

Landforms along the Pacific, Gulf of Mexico, and Atlantic coastlines for the conterminous United States are attributed with the relative vulnerability of horizontal erosion due to sea-level rise to characterize coastal zone stability. The position and extent of landforms are geospatially indexed as line-events where these coastal zone features are intersected by the linear-referenced 2013 - 2014 U.S. Geological Survey National Hydrography Dataset Coastline, which corresponds to the National Oceanic and Atmospheric Administration (NOAA) 2013 - 2014 mean high water level datum delineated in intertidal zones open to oceans, behind barrier coasts in bays, lagoons, and estuaries, and sometimes where tidal currents reach...
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...

The NFHAP Coastal Spatial Framework and Indicator Datasets consist of a geospatial base layer developed in ArcGIS, and associated data fields joined to the spatial framework. The Coastal Spatial Framework is a layer of 612 distinct polygons covering coastal areas of the Continental U.S. Polygons represent either coastal watersheds (land) or coastal waters (estuaries, inshore marine, offshore marine),and are classified into six regions and 22 nested subregions. Each polygon is assigned a unique code (UniqueID) to provide location reference for indicator data, and enable joins to separate data tables.s for information recorded in the Bibliography and Assessment tables. Key indicator data fields attributed to each...

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...

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 southeastern U.S. supports high diversity of freshwater mussels; however, many of these species are in decline (Williams et al. 1993). Impacts from multiple sources, including land use change, conflicting water resource demands, and pollution have placed many species on the threatened and endangered list. Furthermore, changing temperature and precipitation patterns attributed to climate change are altering the aquatic landscape such that habitat suitable in the present may not be suitable in the future (Daraio & Bales 2014; Daraio et al. 2014). The United States Fish and Wildlife Service (USFWS), together with partnering agencies through the South Atlantic Landscape Conservation Cooperative (SALCC), requested...

This data is for planning purposes only. LCCs are applied conservation science partnerships with two main functions. The first is to promote collaboration among their members in defining shared conservation goals. With these goals in mind, partners can identify where and how they will take action, within their own authorities and organizational priorities, to best contribute to the larger conservation effort. The second function of LCCs is to provide the science and technical expertise needed to address the shared priorities and support conservation planning at landscape scales – beyond the scope and authority of any one organization. The organizational model of the LCC Network was intentionally structured to operate...
