This indicator depicts marshes and grasslands along the coast of Louisiana and Texas that are important for mottled duck nesting, based on key biological parameters such as patch size, land cover type, and distance to brood rearing habitat. It originates from a mottled duck decision support tool developed by the Gulf Coast Prairie Landscape Conservation Cooperative.Reason for SelectionThe mottled duck is a non-migratory waterfowl species endemic to the Gulf coast that relies on a unique mix of coastal marshes and nearby grassland habitat for foraging, nesting, and raising young. The West Gulf Coast mottled duck population has declined significantly since the mid-1990s due to habitat loss from urban growth, agricultural...

This layer depicts the extent of Southeast Conservation Blueprint 2022. It was created by dissolving the polygons in the Southeast Blueprint 2022 Input Areas layer using the “SeBlueprin” field.
The Southeast Conservation Adaptation Strategy (SECAS) and Southeast Blueprint Blueprint continue to build on years of investment by the U.S. Fish and Wildlife Service (USFWS) and partners to develop, refine, and apply conservation blueprints to advance on-the-ground conservation actions across the region. Astute Spruce, LLC and the USFWS collaborated closely in the first phase of this project “Enhanced User Engagement with Conservation Blueprints in the Southeastern U.S.” (F19AC00609) to develop a pilot version of the Southeast Conservation Blueprint Explorer specifically intended to make it easier to access, engage with, and interpret the Southeast Conservation Blueprint and underlying sub-regional conservation...

This indicator represents grasslands in the interior southeastern United States, which support important plants, birds, and pollinators. It includes grasslands with and without trees that are historically maintained by geology (e.g., outcrops, glades, and barrens), fire (e.g., Piedmont prairies), and/or the regular violent flooding on the banks of high-energy rivers known as “riverscour” (e.g, riverscour prairies). Known grasslands receive the highest scores, followed by bumble bee habitat buffers around known sites, areas in potentially compatible management, and restoration opportunities within grassland geology. This indicator combines data from multiple sources, including the Southeastern Grasslands Initiative,...

This cultural resource indicator is an index of sites on the National Register of Historic Places surrounded by limited urban development. It identifies significant historic places that remain connected to their context in the natural world. This indicator originates from the National Park Service and various state historic resource agencies. Reason for Selection Low-urban historic landscapes indicate significant cultural landscapes whose cultural context has been less impacted by urban growth. Cultural landscapes are “properties [that] represent the combined works of nature and of man” (UNESCO 2012). Reductions in natural habitat within these cultural landscapes reduce their overall historic and cultural value....

This indicator captures how far upstream migratory fish in the Gulf of Mexico have been observed. How far upstream migratory fish can travel reflects not just the presence of dams and other barriers, but also the presence of measures like fish ladders that allow specific species to access habitat upstream of dams. This indicator originates from The Nature Conservancy’s Southeast Aquatic Connectivity Assessment Project and applies to the Environmental Protection Agency’s estimated floodplain, which spatially defines areas estimated to be inundated by a 100-year flood, also known as the 1% annual chance flood.Reason for SelectionMigratory fish presence reflects uninterrupted connections between freshwater, estuarine,...

This indicator measures the amount of natural landcover in the estimated floodplain of rivers and streams within each catchment. It assesses the stream channel and its surrounding riparian buffer, measuring the percent of unaltered habitat like forests, wetlands, or open water (rather than agriculture or development). This indicator originates from the 2019 National Land Cover Database and applies to the Environmental Protection Agency’s estimated floodplain, which spatially defines areas estimated to be inundated by a 100-year flood, also known as the 1% annual chance flood.Reason for SelectionHabitat near rivers and streams is strongly linked to water quality and instream flow (Naiman 1997), is easy to monitor...

The Southeast Blueprint 2022 Development Process is a final report that explains in detail how this version of the Blueprint was created. It combines the metadata available on the Blueprint page of the SECAS Atlas for the indicators, combined Zonation results, hubs and corridors, and final Blueprint priorities. It is intended to serve as a comprehensive guide to the Southeast Blueprint data sources and methodology that could enable an interested reader to reproduce the Blueprint independently.

The Blueprint uses a least-cost path connectivity analysis to identify connections between priority areas. A program called Linkage Mapper defines corridors that link hubs across the shortest distance possible, while also routing through as much Blueprint priority as possible. Inland corridors connect large patches of highest priority Blueprint areas and/or protected lands. Marine and estuarine corridors connect large estuaries and/or large patches of highest priority Blueprint areas, within broad marine mammal movement areas.INLAND HUBS & CORRIDORSINLAND RESISTANCE RASTERThis is the resistance raster or cost surface used in the Linkage Mapper-based connectivity analysis for the inland portion of the Base Blueprint...

The Southeast Blueprint User Guide is a resource to help conservation professionals use the Blueprint to bring in new resources and inform decision-making. It compiles different examples of real Blueprint uses to provide new ideas about how to connect to this larger strategy. It showcases the approaches, wording, and maps that Blueprint staff have found to work best in different situations. It showcases a range of case studies, grouped into a few themes that summarize the primary ways people have used the Blueprint.

This indicator measures the average percent of non-impervious cover within each catchment. It originates from the 2019 National Land Cover Database percent developed impervious layer. Reason for Selection Impervious cover is easy to monitor and model, and is widely used and understood by diverse partners. It is also strongly linked to water quality, estuary condition, eutrophication, and freshwater inflow. The 90% permeable surface threshold (i.e., 10% impervious) is a well-documented signal of major, negative changes to aquatic ecosystems (Schueler et al. 2009). The 95% permeable surface threshold (i.e., 5% impervious) has been documented to impact Piedmont fish [tricolor shiner (Cyprinella trichroistia), bronze...

This indicator prioritizes areas for reforestation within the Mississippi Alluvial Valley (MAV) based on benefits to three species of forest breeding birds that depend on large interior cores of bottomland hardwood habitat (Swainson’s warbler, cerulean warbler, swallow-tailed kite). The model considers the core size, number of cores, and percent of local forest cover that would result from reforestation, as well as risk of conversion to agriculture based on flooding frequency. The highest scores represent drier areas where reforestation would create new forest patches containing interior cores at least 2,000 ha (~5,000 ac). It originates from the Lower Mississippi Valley Joint Venture’s MAV forest breeding bird...

This indicator represents the condition and location of playas, which are round, shallow depressions found primarily in the western Great Plains that serve as temporary wetlands by collecting water from rainfall and runoff. It defines a healthy playa as one that is not farmed, hydrologically modified, within a wind farm, or impacted by sediment accumulation due to agriculture. It also considers the increased benefits to wildlife provided by clusters of nearby playas, compared to more sparsely distributed playas. This indicator originates from the Playa Lakes Joint Venture’s probable playas dataset.Reason for SelectionThe unique wet-dry cycle that characterizes this important wetland ecosystem makes playas a biodiversity...
This indicator measures the condition of migratory fish habitat along the Atlantic coast within each catchment, using metrics of water quality, aquatic connectivity, habitat fragmentation, flow alteration, and more. Areas of excellent fish habitat are already in good condition and face few threats; restoration opportunity areas are doing well in some respects, but restoration projects could significantly improve them; degraded areas of opportunity face many challenges, and restoration projects are unlikely to increase available fish habitat unless particularly large in scope and scale. This indicator originates from the Atlantic Coast Fish Habitat Partnership’s fish habitat conservation area mapping and prioritization...

This indicator represents important habitat for island-dependent species across the Southeast. The highest scores go to island critical habitat for six threatened and endangered animal and plant species: piping plover, loggerhead sea turtle, Cape Sable thoroughwort, Florida semaphore cactus, silver rice rat, and Bartram’s hairstreak butterfly. This indicator originates from U.S. Fish and Wildlife Service critical habitat data and island boundaries from the U.S. Geological Survey and Esri.Reason for SelectionIslands provide important habitat for many species, including birds, sea turtles, mammals, insects, and plants. Their relative isolation from disturbance and mainland predators can make them important breeding...
