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.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)” as the metric for this indicator. Other evaluation attributes included...

This indicator is an index based on the size of freshwater and saltwater marsh patches. Patch size thresholds are based on the habitat needs of four species of marsh birds.Reason for SelectionLarger, better connected wetlands are positively associated with fish (Meynecke et al. 2008), shrimp (Turner 1977), and marsh birds. In particular, seaside sparrow (Benoit and Askins 2002, Rush et al. 2009), saltmarsh sharp-tailed sparrow (Benoit and Askins 2002), and marsh wren (Rush et al. 2009) have been associated with marsh area effects. Other species are expected to be limited based on home range size. In addition, wave attenuation increases with wetland area (Shepard et al. 2011). Over time, a decrease in patch size...

This database contains the data inputs used to create a 30 meter resistance layer for the Western Washington Habitat Connectivity Assessment. All input data were clipped to the study area and converted to 30 meter raster format in the same projection with matching cell alignment unless otherwise noted. Input data was reclassified as needed in order to assign resistance values.We made three different resistance surfaces, using these data inputs, for testing in sensitivity analyses. For the first, we started with a conventional methodology for creating resistance surfaces (Using Gnarly Landscape Utilities), and then combined this result with nuanced layers about road impacts and building density impacts. These nuanced...

The Desert Landscape Conservation Cooperative (LCC) is a partnership formed and directed by resource management entities as well as interested public and private entities in the Mojave, Sonoran, and Chihuahuan Desert and montane sky island regions of the southwestern United States and northern Mexico. Desert LCC science depends on access to transboundary base datasets. Given the importance of vegetation such as grasslands and riparian vegetation in conservation science, a bi-national, landscape-scale vegetation data layer with classes relevant to Desert LCC research is crucial. One objective of this project is to investigate appropriate methodologies and landscape scales to create a Desert LCC binational land cover...

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 measures the condition of estuarine fish habitat along the Atlantic coast. It incorporates metrics of water quality, marsh edges, seagrass and oyster reefs, fragmentation, human development, 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.Reason for SelectionThis indicator captures many factors influencing the condition of Atlantic estuarine fish habitat quality. It...
The Blueprint 2021 Development Process is a final report that explains in detail how the Conservation Blueprint was created. It first provides an overview of the South Atlantic Blueprint framework, then combines the metadata available on the Conservation Planning Atlas for all indicators, ecosystem integrity scores, hubs and corridors, and final Blueprint priorities. It is intended to serve as a comprehensive guide to the South Atlantic Blueprint objectives, data sources, and methodology that could enable an interested reader to reproduce the Blueprint independently.

Overall Approach The South Atlantic Ecosystem Indicators (30 m resolution) were spatially modeled, tested, reviewed, and used as inputs identify areas of high ecosystem integrity. To aid in the modeling process, we first removed areas with low conservation value, like most developed areas, as well as reservoirs. These areas would not be prioritized in the Blueprint anyway. The indicators then served as inputs into Zonation, a conservation planning framework and software that produces a hierarchical prioritization of the landscape. We ran Zonation within the six separate inland subregions of the South Atlantic. Zonation ranks the pixels in each subregion according to the current condition of the indicators, using...

The Southeast Conservation Blueprint is a map of important areas for conservation and restoration across the Southeast and Caribbean. The Blueprint is the primary product of the Southeast Conservation Adaptation Strategy (SECAS). Through SECAS, diverse partners are working together to design and achieve a connected network of lands and waters that supports thriving fish and wildlife populations and improved quality of life for people.
The goal of the project was to help more efficiently achieve a resilient Appalachian forest landscape within the NALCC geography that is built upon a broadly shared vision for a sustainable, connected mosaic of forest habitats and waters that are home to thriving intact ecosystems and human communities. This project was intended to identify and showcase efforts that, in the light of advances in climate adaptation, best contribute to effective landscape conservation actions in the region.This NALCC demonstration project was to cover a broadly defined super-region within the NALCC geography – the Appalachian forests that extend from the hills west of the Appalachian Mountains, east to the Piedmont. As such, it was...

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.Reason for SelectionLow-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.Input Data South Atlantic Blueprint 2021 extent 2016 National Land Cover Database (NLCD): Used to define...

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...
