         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:
      Habitat for least terns was based on water depth, cover type,
      and recent and historic nesting occurrences.
      For details see the model narrative: least_tern_model.htm
    Purpose:
      Habitat suitability information mapped for this and for 62
      other species of concern in the Gulf of Maine will be used
      to identify valuable areas for conservation, protection and enhancement of plant, fish and wildlife habitat.

DATA_QUALITY_INFORMATION Attribute_Accuracy: Attribute_Accuracy_Report: The accuracy of the attributes is determined by the scale and quality of the data sets used, which may have errors in characterizing land cover, soil, or other environmental condition. Logical_Consistency_Report: This raster data set is based on a descriptive model, applied to available GIS datasets. Completeness_Report: The coverage may omit useful habitat or erroneously identify habitat because of limitations of the source data and the models operating on those data. Habitat identification was limited by the spatial resolution of the underlying data and the quality and age of information available. The species may not be found in all the habitats shown, or may be found in additional areas; the information provided may not accurately portray most recent conditions. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Data set accuracy generally corresponds to that of the 1:24,000 base data used to align the raster data.

Occurrence data was obtained from the Massachusetts and New Hampshire Natural Heritage Programs, surveys from Massachusetts Division of Fisheries & Wildlife, and data from Maine least tern and piping plover surveys (Jones et al. 1999). Areas within 1/4 mi of recent least tern nests and having suitable cover were scored 1.0; areas within 1/4 mi of historic tern nests or of active piping plover nests and having suitable cover were scored 0.4. Other areas not documented as nest sites, but with adequate expanses of apparently suitable cover were scored 0.2. Mapping of potential nesting habitat was done only within the Ecological Regions (USDA Forest Service Ecological subunits, Keys et al. 1995) hosting recent nest sites. Foraging habitat was mapped as suitable estuarine or marine cover types within 1 mile of recent least tern nest sites and less than 60 feet deep. Such areas were scored 0.3, to distinguish them from nesting cover and because of the lack of specificity in mapping.
