This data set contains sensitive biological resource data for threatened/endangered and rare reptiles in Alabama. Vector polygons in this data set represent the rare turtle and snake occurrences. Species-specific abundance, seasonality, status, life history, and source information are stored in relational data tables (described below) designed to be used in conjunction with this spatial data layer.This data set comprises a portion of the Environmental Sensitivity Index (ESI) data for Alabama.

This data set contains human-use resource data for airports, archaeological and historic sites, beaches, boat ramps, state borders, bridges, and marinas for Alabama. Vector points and lines in this data set represent the human-use site locations. Location-specific type and source information are stored in relational data tables (described below) designed to be used in conjunction with this spatial data layer. This data set comprises a portion of the Environmental Sensitivity Index (ESI) data for Alabama.

This data set contains sensitive biological resource data for Alabama and Perdido Key beach mice in Alabama. Vector polygons in this data set represent the rare terrestrial mammal distribution. Species-specific abundance, seasonality, status, life history, and source information are stored in relational data tables (described below) designed to be used in conjunction with this spatial data layer.This data set comprises a portion of the Environmental Sensitivity Index (ESI) data for Alabama.

This data set contains biological resource data for alcids, shorebirds, waterfowl, diving birds, pelagic birds, gulls and terns in the Aleutian Islands, Alaska. Vector polygons in this data set represent locations of bird nesting, foraging, and rafting sites.

This data set contains vector lines and polygons representing the shoreline and coastal habitats of the Aleutian Islands classified according to the Environmental Sensitivity Index (ESI) classification system.This data set comprises a portion of the ESI data for Aleutians East Borough and Aleutians West Coastal Resource Service Area (CRSA). These data identify the marine and coastal environments and wildlife. The ESI data include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources.

This data set is a compilation of faults mapped by the United States Geological Survey (USGS) and published in USGS bulletin series 1028 (1956-1971). These bulletins are the last published attempt at mapping structure and stratigraphy of the Aleutians on an island-by-island basis. Only faults that manifest themselves on land were included in the USGS reports. Faults were transcribed from these bulletins onto the ESI maps. On the ESI maps, the faults are portrayed as linear features, with no map indication of their type (normal vs.

This data set contains biological resource data for estuarine, benthic, and pelagic fish in the Aleutian Islands, Alaska. Vector polygons in this data set represent locations of fish concentration areas. Species-specific abundance, seasonality, status, life history, and source information are stored in relational data tables (described below) designed to be used in conjunction with this spatial data layer.This data set comprises a portion of the Environmental Sensitivity Index (ESI) data for Aleutians East Borough and Aleutians West Coastal Resource Service Area (CRSA).

This data set contains biological resource data for anadromous fish streams in the Aleutian Islands, Alaska. Vector lines in this data set represent locations of fish streams. Species-specific abundance, seasonality, status, life history, and source information are stored in relational data tables (described below) designed to be used in conjunction with this spatial data layer.This data set comprises a portion of the Environmental Sensitivity Index (ESI) data for Aleutians East Borough and Aleutians West Coastal Resource Service Area (CRSA).

This data set contains point locations of geothermally active areas as compiled by Motyka et al., 1993. Because of the variety of geothermal activity present at any given site, each site has been mapped according to the dominant style of geothermal activity (i.e. water dominated sites, vapor dominated sites, or sites of known subsurface activity).

This data set contains biological resource data for seagrasses in the Aleutian Islands, Alaska. Vector polygons in this data set represent locations of seagrass concentration areas. Species-specific abundance, seasonality, status, life history, and source information are stored in relational data tables (described below) designed to be used in conjunction with this spatial data layer.This data set comprises a portion of the Environmental Sensitivity Index (ESI) data for Aleutians East Borough and Aleutians West Coastal Resource Service Area (CRSA).
