This indicator represents the presence of seagrass in the Atlantic Ocean and Gulf of Mexico. It originates from the National Oceanic and Atmospheric Administration’s Marine Cadastre.Reason for SelectionSeagrasses provide food and habitat for a range of marine and estuarine wildlife, including fish, sea turtles, shrimp, crabs, oysters, and more. They also produce oxygen, filter water, control erosion, and buffer storms. Seagrasses serve as an important indicator of the overall health of coastal ecosystems because they are sensitive to water quality and require sufficiently clear water for sunlight to penetrate (NPS 2021, NOAA 2021, NWF 2021).Input Data Base Blueprint 2022 extent Base Blueprint 2022 subregions Seagrasses...

This indicator represents Priority Amphibian and Reptile Conservation Areas (PARCAs) in the South Atlantic. PARCA is an expert-driven, nonregulatory designation that includes places capable of supporting viable amphibian and reptile populations, places occupied by rare or imperiled species, and places rich in biodiversity or species unique to that geographic area (i.e., endemism).Reason for SelectionThe Southeast United States is a global biodiversity hotspot that supports many rare and endemic reptile and amphibian species (Barrett et al. 2014, EPA 2014). These species are experiencing dramatic population declines driven by habitat loss, pollution, invasive species, and disease (Sutherland and deMaynadier 2012,...

This indicator combines measures of water quality, sediment quality, contaminants in fish tissue, and benthic community condition to create an overall index of coastal estuarine condition. It originates from the Environmental Protection Agency’s National Coastal Condition Assessment data.Reason for SelectionThis index measures the condition of the nation’s estuaries following standard national methodologies and is synthesized by the U.S. Environmental Protection Agency (EPA) roughly every five years. Estuaries serve as important nursery habitat for wildlife, including many species of fish and shellfish eaten as seafood. They also improve water quality by filtering out sediments and pollutants, provide recreational...

This layer depicts the mosaiced, rebalanced Zonation results for each subregion in Base Blueprint 2022.OVERALL APPROACHThe Base Blueprint indicators (available on the Blueprint page of the SECAS Atlas) were modeled at a 30 m resolution, tested and reviewed, and used as inputs to identify priority areas for a connected network of lands and waters. To aid in the modeling process, we first removed highly altered areas, like most developed areas, as well as reservoirs. Generally, these areas would not be prioritized in the Blueprint anyway.The indicators then served as inputs into Zonation, a conservation planning framework and software program that produces a hierarchical prioritization of the landscape. We ran Zonation...
Lists of species of greatest conservation need (SGCN) are powerful tools for revealing shared conservation priorities, enhancing collaboration, and securing additional conservation funding. In the northeastern US, such a list has served as a foundation for multi-state collaborations for conservation implementation.States in the Southeastern Association of Fish and Wildlife Agencies (SEAFWA) region have identified 6,682 SGCN in their wildlife action plans. Collaboratively developing a more targeted list of regional SGCNs will reflect shared conservation values and stewardship responsibilities, encourage cross-state work on those priority species, and substantively contribute to realization of the Southeast Conservation...

This indicator identifies areas within the historic longleaf pine range east of the Mississippi River where creating or maintaining open pine habitat would most benefit six focal species of birds (Bachman’s sparrow, red-cockaded woodpecker, Henslow’s sparrow, red-headed woodpecker, Northern bobwhite, brown-headed nuthatch). It prioritizes areas for open pine conservation based on suitability for longleaf pine, feasibility of prescribed burning, proximity to protected lands, habitat suitability for focal bird species, and proximity to source bird populations. It originates from the East Gulf Coastal Plain Joint Venture’s prioritization of areas for open pine ecosystem restoration.Reason for SelectionOpen longleaf...

This indicator assesses shoreline condition based on the presence of hardened structures like jetties, groins, and riprap, as well as other human development. Natural shorelines in harder-to-develop coastal areas receive the highest shoreline condition scores, while hardened shorelines receive the lowest scores. This indicator originates from the National Oceanic and Atmospheric Administration’s Environmental Sensitivity Index dataset.Reason for SelectionHuman development along shorelines, along with jetties, groins, seawalls, revetments, and other structures, provide a measure of overall habitat alteration and shoreline condition. Human infrastructure along shorelines generally stabilizes barrier islands, impeding...

This indicator depicts maritime forest currently present in the South Atlantic. It originates from Landfire Existing Vegetation Type data.Reason for SelectionOverall acreage of existing maritime forest provides an indicator of whether maritime forest being inundated by sea-level rise is being replaced or restored somewhere else. Since maritime forest has been substantially reduced from its historic extent, protecting the remaining acreage of existing maritime forest is important. It is also well monitored and resonates with a diversity of audiences.Input Data South Atlantic Blueprint 2021 extent Base Blueprint 2022 subregions LANDFIRE (Existing Vegetation Type), accessed 3/31/2021Mapping Steps Extract the LANDFIRE...

This indicator uses remote sensing to calculate the unvegetated-vegetated ratio of tidal wetlands, which compares how much of a wetland is not covered by plants (e.g., sediment, rocks, open water) to how much is covered by plants. It originates from a U.S. Geological Survey project on an unvegetated to vegetated ratio for coastal wetlands.Reason for SelectionThreats like sea-level rise, erosion, and development are driving widespread salt marsh loss. Tidal marshes protect coastlines from storms, filter pollution to improve water quality, and provide important habitat for birds, fish, and shellfish. Studies show that the unvegetated-vegetated ratio (UVVR) of tidal marshes serves as a good surrogate for marsh degradation...
Longleaf pine (Pinus palustris) ecosystems in the southeastern United States have declined substantially from an estimated 92 million acres in the pre-Columbian time period to 4.3 million acres at present, largely due to agricultural conversion, urbanization and replacement by other forest types, notably loblolly pine (Pinus taeda). The open landscape character of longleaf pine ecosystems is characterized by a lower carbon stocking and prairie-like understory dominated by grasses and low woody vegetation . Lower carbon stocking combined with greater drought tolerance in longleaf pine suggest that longleaf pine stands generally consume less water relative to loblolly pine and slash pine dominated stands. The...

This indicator uses remote sensing to estimate the number of times an area has been burned from 2013 to 2021. It combines burned area layers from both U.S. Geological Survey Landsat data and the inter-agency Monitoring Trends in Burn Severity program. Landsat-based fire predictions within the range of longleaf pine are also available through Southeast FireMap.Reason for SelectionMany Southeastern ecosystems rely on regular, low-intensity fires to maintain habitat, encourage native plant growth, and reduce wildfire risk. Historically in the South, “fires burned as often as once a year or more in Coastal Plain pine systems or as infrequently as every 50 years or more on north-facing or cove sites in the mountains”,...

The Blueprint uses a least-cost path connectivity analysis to identify connections between priority areas. A program called LinkageMapper 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, within broad areas of established conservation interest for connectivity. 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...
