Essential Fish Habitat depth polygon.

This data set contains sensitive biological resource data for reef, pelagic, benthic, and estuarine fish species in Guam and the Northern Mariana Islands. Vector polygons in this data set represent 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 Guam and the Northern Mariana Islands. ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil. The ESI data include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources.

This data set contains sensitive biological resource data for benthic marine habitats and plants in Guam and the Northern Mariana Islands. Vector polygons in this data set represent benthic marine habitats (e.g. coral reefs, seagrass) and sensitive/rare plant 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. See also the BENTPT (Benthic Points) data layer, part of the larger Guam and Northern Mariana Islands ESI database, for additional benthic habitat information.The HABITATS data set comprises a portion of the Environmental Sensitivity Index (ESI) data for Guam and the Northern Mariana Islands. ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil. The ESI data include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources.

This file represents salmonid freshwater and estuarine Essential Fish Habitat (EFH) in the western United States. Congress, through the Magnuson-Stevens Act, defined EFH as "those waters and substrate necessary to fish for spawning, breeding, feeding, or growth to maturity." This dataset follows the federal codification of delineating EFH using 4th field Hydrologic Units. It spatially depicts designated EFH for Federally-managed Pacific salmon within freshwater and estuarine regions of California, Oregon, Washington, and Idaho. Areas above identified certain impassible dams are not designated EFH, and these have been removed from the 4th field Hydrologic Units. Only areas defined as EFH are present in this dataset. Each Hydrologic Unit polygon has been coded to indicate for which species of salmon (Chinook salmon, coho and/or pink) it represents EFH.

This data set contains sensitive biological resource data for dolphins in Guam and the Northern Mariana Islands. Vector polygons in this data set represent marine mammal 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 Guam and the Northern Mariana Islands. ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil. The ESI data include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources.

This data set contains vector polygons representing the coastal wetland habitats for Guam and the Northern Mariana Islands classified according to the Environmental Sensitivity Index (ESI) classification system. This data set comprises a portion of the ESI data for Guam and the Northern Mariana Islands. ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil. The ESI data include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources. See also the ESI (ESI Shoreline Types \x96 Lines) data layer, part of the larger Guam and Northern Mariana Islands ESI database, for additional coastal habitatinformation.
