Colonial Waterbirds Important Nesting Habitat (250-meter grid spacing)
- This layer shows important nesting sites for colonial nesting waterbirds, based on a dataset that originated from the Massachusetts Division of Fisheries and Wildlife Natural Heritage and Endangered Species Program (DFW/NHESP). These sites represent areas where more than 100 pairs of the following species of colonial nesting waterbirds were observed during surveys in 1994 and 2006: Common Terns, Least Terns, Roseate Terns, Arctic Terns, Leach's Storm-Petrels, Double-crested Cormorants, Herring Gulls, Great Black-backed Gulls, Laughing Gulls, Black Skimmers, Great Egrets, Snowy Egrets, Cattle Egrets, Little Blue Herons, Black-crowned Night Herons, and Glossy Ibis. The important habitat areas are the nesting sites buffered 0.3 nautical miles. To allow for consistent evaluation and comparison of a variety of datasets with distinct spatial resolutions, accuracies, and other characteristics, the Massachusetts ocean management planning area was partitioned into 250 x 250-meter grid cells, each with a unique ID. These data were converted to the planning area grid by extracting all of the cells in which the data layer occurred.
