Abstract

SNI contains POLYGONS that represent NRPA (Natural Resource Protection Act) regulated coastal seabird nesting islands or portions thereof along the coast of Maine. This dataset is included in the statewide seabird nesting island database maintained by MDIFW. See metadata for "Seabird Islands (LURC)" descriptions of seabird islands under LURC jurisdiction (available through MDIFW). Other seabird nesting islands may exist which do not qualify for regulation under NRPA.

Purpose

The data layer is a subset of the statewide dataset. Data is representative of periodic survey efforts since 1976.

Supplemental Information

Seabird Nesting Islands (SNI) have been formally adopted as a NRPA habitat through the MEDEP regulatory process. Description: Significant Wildlife Habitat Seabird Nesting islands are (a) an island, ledge, or portion thereof in tidal waters that has documentation of 25 or more: nests, adult seabirds associated with nests or combination thereof (single species or aggregate of different species) in any nesting season during, or since 1976; provided that the island, ledge, or portion thereof continues to have suitable nesting habitat. (b) an island, ledge, or portion thereof in tidal waters that has documentation of one or more nests of a seabird that is a Maine endangered or threatened species in any year during or since 1976 provided that the island, ledge, or portion thereof, continues to have suitable nesting habitat.

A list of all twenty-one (21) HUC8 names and numbers is available in a table "HUCLUT", at the Data Catalog "Tables" link. Corresponding 12 digit HUC names and numbers are also included in the table. Three methods of selection are available from the Internet Data Catalog to suit your needs: 1) To obtain a downloadable list of all the HUC8 watersheds use Select by County on HYD24, and select all counties. The result will be by county and include all HUC8 watershed names and numbers with some, but minimum, overlap to choose from for download. 2) If you want to limit your download to a specific hydrography feature use Select by Watershed, which will provide a list of HUC12 names of local features to select from. The result will provide only the corresponding 8 digit HUCs to download.3) For advanced search and query statewide, download the data layer WBDME6_A. The data layer contains boundaries, name and number attribution for 6, 8, 10, 12 digit HUCs and can be used as an index for each of these levels of watersheds.

Source Contribution

Recently MDIFW coastal island delineations were incorporated into HYD24. The data improved delineation of islands from the original 24k base COAST layer, added islands monitored by MDIFW (most fully or partially submerged at high tide) , added an ISLANDID, and a CIREG indicator for each island. The depiction, ISLANDID and NAME attribution of seabird nesting areas in SNI is based on these coastal island polygons.

Entity and Attribute Overview

SNI is a POLYGON dataset that of NRPA regulated coastal seabird nesting islands or portions thereof along the coast of Maine. The dataset is attributed with the Maine Department of Inland Fisheries ISLANDID, NAME, alternate name, ownership type (i.e., private, state, federal, etc.), USGS quadrangle name, and a ZONE identifier for NRPA protection.

Entity and Attribute Detail Citation

The ArcView shapefile and ArcGIS geodatabase formats, commonly used for Maine GIS data, carry default identifiers and attributes that are software generated and/or important for internal recordkeeping. These are listed here to avoid repetition for every layer, and may not be repeated in the attribute descriptions and definitions of each layer. Common software generated identifiers and attributes in Maine GIS data include: FID (feature identifier), Shape (feature geometry), OBJECTID and SHAPE_lengt. In addition, most GIS formats will carry fields for PERIMETER, AREA and/or LENGTH according to feature geometry. These fields are typically available by default, with the units based on coordinate system or projection units of GIS data. Most GIS software packages also provide a means to calculate these values. It is important to test any columns containing PERIMETER, AREA or LENGTH values before using them for analysis purposes. These important values can be carried from format to format and become out-dated. Verify that the values are correct. Also, in your GIS software, please view the properties of data layers for the map units used to calculate these fields, and for the units set for display purposes.

Format Information Content

MEGIS has made all vector layers, in the Maine GIS Internet Data Catalog, available in ESRI's ArcView shapefile format. A shapefile is a simple non-topological format that stores the geometry and attribute information for a set of geographic features as a set of vector (point, line, polygon) coordinates. Shapefiles draw quickly and directly in ArcView, ArcGIS, ArcExplorer. Shapefiles are a compatible data type for many other types of GIS software. Three files are fundamental to each shapefile: .shp stores the feature geometry (shape and location information); .shx stores the index of the feature geometry; .dbf a dBASE (TM) file stores the attribute information for the features. Other index files may be created to help speed analysis and query: these file formats are .sbn .sbx .ain .aix .fbn and .fbx. In addition you may find projection .prj, and metadata .xml, files associated with shapefiles.
