        The Gulf of Maine Habitat Mapping Project used occurrence information and species/habitat models to map potential
        habitat for 63 species of primary concern to the U.S. Fish and Wildlife Service. These include migratory birds,
        anadromous and estuarine fishes, and threatened or endangered species.   The habitat models are based on                
        published literature, agency reports, and knowledge of experts working with the species.

  Description:
    Abstract:
      This coverage combines modeled habitat for three life stages (juveniles/subadults, and adults) of
      horseshoe crabs in a single map.  For details see the model narrative horseshoe_crab_model.htm
    Purpose:
      The purpose of this project was to identify valuable areas for conservation,
      protection and enhancement of plant, fish and wildlife habitat.
    Supplemental_Information:
      Depth Suitability: Only intertidal depths were considered suitable for breeding;  intertidal to -12' was regarded as 
       suitable for juveniles. Only waters to -99' were scored as suitable adult non-breeding habitat.  Salinity Suitability:  
      all areas > 6 ppt were regarded as suitable. Proximity of juvenile to breeding habitats:  juvenile habitat was
      mapped only within a half-mile radius of suitable breeding habitat.  Wave energy/wind fetch: Breeding beaches 
      must be relatively protected from wave action. Suitable conditions were identified as those having wind fetch
      within the range of  8 to 156 30-m cells.  For details see the model narrative horseshoe_crab_model.htm

DATA_QUALITY_INFORMATION Attribute_Accuracy: Attribute_Accuracy_Report: The accuracy of the attributes is determined by the quality of the data sets used, which may have errors in characterizing land cover, depth, or other environmental condition. Logical_Consistency_Report: This raster data set is based on a descriptive model of species needs, applied to available GIS datasets. Completeness_Report: While models disclose areas of high quality habitat, they are limited by the coarseness of scale and the level of detail available in the GIS datasets used for analysis. It is possible that the species could be found in additional areas, and that the information provided may not portray most recent conditions or occupation by the species.
