Resilient Biodiversity Hotspots This layer is an older version of one of the South Atlantic LCC indicators in the landscapes “habitat aggregate”, which is intended to capture connections across all terrestrial ecosystems. It is an index of mostly natural, high-diversity areas potentially resilient to climate change. This indicator was most recently updated in Blueprint 2.2 to incorporate more recent data from TNC’s Resilient Land project. The updated indicator also has 8 categories based on standard deviations from the mean, rather than the two categories in this version, and uses an improved resampling method. Reason for Selection Resilience scores quantify a combination of landscape diversity and local connectedness....

Freshwater Marsh Birds This layer is one of the South Atlantic LCC indicators in the tidal and nontidal freshwater marsh ecosystem. It is an index of potential habitat for five freshwater marsh bird species. Reason for Selection Patch sizes of fresh marsh were ranked with knowledge of marsh bird habitat relationships. Over time, a decrease in patch size will correspond to marsh degradation and wetland loss. Brown and Dinsmore (1986) tested bird responses to wetland patch size in interior fresh marshes. They showed 10 species were not present in wetland patches of < 5 ha, but were included in greater patch sizes. Examples of these species include least bittern, northern pintail, and northern shoveler. Several other...

Low Road Density This layer is an older version of one of the South Atlantic LCC indicators in the landscapes “habitat aggregate”, which is intended to capture connections across all terrestrial ecosystems. It is an index of areas with few roads. This indicator was updated in Blueprint 2.1 to use an improved resampling method. Reason for Selection Large areas with few roads are favorable for conservation of numerous species, including reptiles and amphibians, birds, and large mammals. Roads can cause negative impacts by promoting dispersal of invasive species and inhibiting water flow. Road density, as well as urban expansion in areas of low road density, are straightforward to measure and monitor. Road density...

Longleaf Pine Extent This layer was one of the early South Atlantic LCC indicators in the pine and prairie ecosystem. It captured the overall acres of longleaf pine in the South Atlantic geography. It has since been removed as an indicator. It was never scored in the 2015 State of the South Atlantic or used in the Blueprint because the data is summarized at too coarse a scale. We plan to revisit this indicator when finer scale data is available to depict longleaf pine extent. Reason for Selection Acres of longleaf pine is one of the cultural resource indicators for the South Atlantic LCC. Longleaf pine was the predominant ecosystem at the time of colonialization, so it contributes to Native Americans’ ability to...
