The South Atlantic Conservation Blueprint is a living spatial plan to conserve natural and cultural resources for future generations. It identifies shared conservation priorities across the South Atlantic region.Blueprint 2021, released in August 2021, is a totally data-driven plan based on terrestrial, freshwater, marine, and cross-ecosystem indicators. It uses the current condition of those indicators to prioritize the most important areas for natural and cultural resources across the South Atlantic geography. Through a connectivity analysis, the Blueprint also identifies corridors that link coastal and inland areas and span climate gradients. The Blueprint reflects extensive feedback from the broader cooperative...

This indicator represents the size of large, unfragmented patches of natural habitat. It identifies minimally disturbed natural areas at least 100 acres in size and greater than 200 meters wide. This indicator originates from Esri’s green infrastructure data.Reason for SelectionLarge areas of intact natural habitat are favorable for conservation of numerous species, including reptiles and amphibians, birds, and large mammals. The Esri Green Infrastructure data covers the entire United States and has been used in other broad-scale conservation planning efforts, so using this existing data helps align the Blueprint with other conservation efforts and reduce duplication of effort. We chose to use “Core Size (acres)”...

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...

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...

In 2012, the South Atlantic Landscape Conservation Cooperative (SALCC) began development of its process to select natural resource indicators and targets as specific landscape scale measures of success for natural resources. An indicator was defined by the SALCC as a metric designed to inform easily and quickly about the conditions of a system, where as a target is a numeric goal established for an indicator. Recommendations were made to the SALCC steering committee in March to recommend indicators for aquatic and terrestrial ecosystems. Recommendations were based on input from 235 experts in marine, freshwater and terrestrial resources in the SALCC geography and adjacent LCCs. Indicator recommendations were considered...

The South Atlantic Landscape Conservation Cooperative (SALCC) project area supports a wide variety of critical estuarine and marine habitats. However, the existing maps of these resources were created at different scales and are housed in a variety of locations. This can be challenging for users and limits their utility for a regional approach to analysis. Looking across boundaries is important to understanding relative value when making habitat conservation decisions. With this project, The Nature Conservancy (TNC) proposes to: (1) develop a suite of regional natural resource maps for the South Atlantic; (2) create a report describing data source, analytical methods and mapping results that includes a summary of...
