Essential Fish Habitat Mapper v3.0
The EFH Mapper is a one-stop tool for viewing the spatial representations of fish species, their life-stages and important habitats. We provide links to supporting materials, including fishery management plans, and the ability to download GIS data.
This one-of-a-kind tool displays maps for essential fish habitat (EFH),habitat areas of particular concern, and EFH areas protected from fishing. You have the ability to discover the species that spawn, grow, or live in a chosen location on the map and generate a report with supporting documentation. For species with distinct life-stages, the map offers locations for each individual stage.
The purpose of this interactive, online mapping application is to provide the public and other resource managers an interactive platform for viewing a spatial representation of EFH, or those habitats that NMFS and the regional fishery management councils have identified and described as necessary to fish for spawning, breeding, feeding or growth to maturity.
Information available for viewing in the EFH Mapper includes EFH, habitat areas of particular concern (HAPCs), and EFH areas protected from fishing, where NMFS and the regional fishery management councils have used the EFH provisions established in Section 303 (a)(7) of the Magnuson-Stevens Fishery Conservation and Management Act to prevent, mitigate, or minimize adverse effects from fishing on EFH.
The data in this mapping product were developed using methodologies that reflected regional differences in both source data and management needs. Because of the variability in the quality and intended usage of these GIS data layers, each should be considered individually when interpreting the accuracy and utility of the information that they provide. Please be sure to view the EFH data inventory and read the information in the Data Quality tab to fully understand the usage constraints for each data layer and the completeness and accuracy of the information that the EFH Mapper provides.
