Publicly accessible open spaces provide valuable opportunities for people to exercise, play, socialize, and build community. People are more likely to use public open spaces that are close (ideally within walking distance) to their homes. To assess the spatial distribution of access to open space for recreation in the southeastern United States, we constructed an index of open space access based on the size of the largest publicly accessible open space within 10 miles of each point on the landscape, using three distance categories to represent whether people can reach the open spaces by walking (within 0.5 mile), via a short drive (within 3 miles), or via a longer drive (within 10 miles). Using the open space access...

This data set contains links that are important to each species' habitat network. Those important links are scored based on the percent currently under protection status, projected change in climate suitability by the middle of the 21st century, and projected change in percent urbanized by the middle of the 21st century. Important links were identified from all links in the networks of each species based on their Integral Index of Connectivity (dIIC). Any links with dIIC scores > 0.9 or which connected to nodes with dIIC > 0.9 were retained here as "important" links.

Recreational birding is a popular activity in the United States. To assess the spatial distribution of recreational birding in the southeast, we combined two data sources: eBird (Sullivan et al. 2009) and the National Survey of Fishing, Hunting, and Wildlife-associated Recreation (NSFHWAR; US Department of Interior, Fish and Wildlife Service, and Department of Commerce 2011). We used spatial birding data from eBird to distribute the state-level NSFHWAR birding data by county and land protection status. This information was used to identify priority counties for conservation of birding areas. These are counties with a high level of birding activity where at least 90% of birding activity takes place on unprotected...

Wild insect pollination has significant positive effects on pollinator-dependent crop production. While managed honeybees are often used to provide pollination to pollinator-dependent crops, visits by wild insect pollinators have been shown to be more effective in increasing fruit set than managed pollinators, and wild insect pollination increases fruit set even when managed pollinator visitation is high (Garibaldi et al. 2013). The total value of the pollination services provided by wild, native insects has been estimated at $3.07 billion annually (2003 dollars) in the United States (Losey & Vaughan 2006). To assess the spatial distribution of potential wild insect pollination, we mapped the supply of potential...

In partnership with South Atlantic Landscape Conservation Cooperative members, we assessed current and projected connectivity for three species that inhabit bottomland hardwoods throughout the southeastern US: black bear (Ursus americanus), Rafinesque’s big-eared bat (Corynorhinus rafinesquii), and timber rattlesnake (Crotalus horridus). For each species, we mapped important habitat connections between core patches of habitat using three different modeling approaches (Connectivity Analysis Toolkit (CAT), Circuitscape, and Linkage Mapper) that incorporated three types of resistance layers (expert opinion, niche modeling, and empirical data for the black bear only). The result was 21 sets of important connections,...

Clean water is important for a variety of uses, including drinking, recreation, and as habitat for aquatic species. Nonpoint-source pollution, such as nutrients, sediment, and pesticides from agricultural runoff, is a major cause of impaired water quality in the United States . Vegetation and soil in natural land cover help to remove pollutants from runoff water before it reaches streams and other waterways by slowing water flow and physically trapping sediment. To assess the spatial distribution of water purification potential in the southeastern United States, we mapped the demand for purification as the total area of agricultural land and the supply of natural land cover in the flowpath over which water moves...

This information was used to identify priority watersheds for conservation of birding areas. These are watersheds with a high level of birding activity where at least 90% of birding activity takes place...

Coastal wetlands purify water, protect coastal communities from storms, sequester (store) carbon, and provide habitat for fish and wildlife. They are also vulnerable to climate change. In particular, changes in winter climate (warmer temperatures and fewer freeze events) may transform coastal wetlands in the northern Gulf of Mexico, as mangrove forests are expected to expand their range and replace salt marshes. The objective of this research was to evaluate the ecological implications of mangrove forest migration and salt marsh displacement. As part of this project, researchers identified important thresholds for ecosystem changes and highlighted coastal areas in the southeastern U.S. (e.g., Texas, Louisiana,...

This shapefile contains polygons representing the current range of twelve ecosystems in the southeastern U.S. and the Caribbean. These were the focal ecosystems for the research project. The polygons were created by digitizing a representative area that contained each ecosystem's extent, as defined from GAP land cover or NatureServe's National Map land cover data.

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...
