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 DataThe National Register of Historic Places reflects what Americans value in their historic built...

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...

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.Southeast Blueprint 2021 Input AreasThis layer depicts the areas where each Blueprint input was used in Southeast Blueprint 2021. It is also the best current approximation of the analysis extent for each subregional Blueprint input. It can serve as a resource for determining which of...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
