Abstract:
This GRID identifies habitat suitability in the U.S. portion of the Gulf of Maine watershed for 13 declining songbird species. Habitats for each species were mapped and ranked from actual sightings or by developing habitat suitability models reflecting environmental requirements for each species. Grids for each species were combined, allowing this 'grouped' grid to be used to display habitats by individual species. Also, scores for each species were summed. This value reflects both the number of species using each cell and the relative habitat suitability for those species. |

Metadata elements shown with blue text are defined in the Federal Geographic Data Committee's (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM). Elements shown with green text are defined in the ESRI Profile of the CSDGM. Elements shown with a green asterisk (*) will be automatically updated by ArcCatalog. ArcCatalog adds hints indicating which FGDC elements are mandatory; these are shown with gray text.

This data may be used to show valuable habitat for USFWS priority trust species in the U.S. portion of the Gulf of Maine watershed. The data may be used at a regional or local level to prioritize habitat protection by local, municipal, state or federal land protection organizations or to support grant applications for habitat protection. It may also be incorporated into local and regional planning to help identify and protect important fish and wildlife habitat.

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. Use of this data set at the local level (parcel or town level) should be supplemented by on-the-ground verification.
This raster data set is based on descriptive models, applied to available GIS datasets.
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. This data set only shows high value habitat for the species included in the analysis; important habitat may exist for other species not included in the analysis.
Data set accuracy generally corresponds to that of the 1:24,000 base data used to align the raster data.
Source is a table of links to models and metadata for habitat grids for all evaluation species.
Habitat scores (value item) for 13 species grids (group songbirds) were combined, retaining the score for each species on a cell by cell basis. The sum of scores for all species also was calculated, on a cell by cell basis.
