Description: This dataset was developed in accordance with Maine's Natural Resources Protection Act (NRPA). Under this Act, the Maine Department of Inland Fisheries and Wildlife (MDIFW) is designated as the authority for determining Significant Wildlife Habitats (SWHs).
Since 1976, islands have been surveyed periodically (not annually) for seabirds. Seabird nesting islands (SNI) are defined as an island, ledge, or portion thereof in tidal waters that has 25 or more documented nests, adult seabirds associated with nests, or combination thereof (single species or aggregate of different species) in any nesting season since 1976 provided that the island, ledge, or portion thereof continues to have suitable nesting habitat. In addition, seabird nesting islands are also defined as an island, ledge, or portion thereof in tidal waters that has one or more documented nests of a seabird that is a Maine endangered or threatened species in any year since 1976 provided that the island, ledge, or portion thereof, continues to have suitable nesting habitat
Seabird Nesting Islands have been formally adopted as a NRPA Significant Wildlife Habitat through the Maine Department of Environmental Protection (MDEP) regulatory process. The SNI dataset contains polygons that represent NRPA regulated coastal seabird nesting islands or portions thereof along the coast of Maine. This coverage is included in the statewide seabird nesting island database maintained by MDIFW. See metadata for "Seabird Islands (LUPC)" for descriptions of seabird islands under Land Use Planning Commission (LUPC) jurisdiction (available through Maine Department of Inland Fisheries and Wildlife (MDIFW)). Other seabird nesting islands may exist that do not qualify for regulation under NRPA. The dataset is a subset of the statewide coverage.
