Along with other plants, eelgrass forms the base of food production in the sea. Eelgrass provides shelter for juvenile fish, and invertebrates, is a site for primary settlement of the larvae of some bivalve mollusks, and in certain locations helps to stabilize unconsolidated sediments and shorelines. In August 2013, Casco Bay was flown and photographed. Photography was timed near low tides with low wind velocity, good water clarity, and maximum biomass of eelgrass. These factors aid in the detection of the subtidal portion a bed. Polygons delineating stands of eelgrass were screen digitized and coded using a four category scale of percent cover. Cover Class values: 1 = 0% to 10% cover, 2 = 10% to 40% cover, 3 = 40% to 70% cover, 4 = 70% to 100% cover. Verification was carried out by boat, on foot, and by plane. Though dense patches of eelgrass approximately 6 meters in diameter and less can be identified under good conditions and in some cases were mapped, a conservative estimate of the minimum mapping unit is 150 square meters. This represents a stand of approximately 14 meters in diameter.", "summary": "Eelgrass and Seagrass beds along the Maine coast have been mapped in order to better understand their importance as habitat, to record the present day distribution, and to aid in the identification of this sensitive.", "title": "Eelgrass", "tags": [ "dep", "environment", "Maine", "Maine DEP", "MaineDEP", "state of maine", "biota", "BIOLOGY", "coastal", "submerged aquatic vegetation", "Zostera marina", "eelgrass", "oceans", "habitat" ], "type": "Map Service", "typeKeywords": [ "Data", "Service", "Map Service", "ArcGIS Server" ], "thumbnail": "thumbnail/thumbnail.png", "url": "", "extent": [ [ -70.8355311576247, 43.0571121296242 ], [ -69.2103459298453, 44.0670481333393 ] ], "minScale": 0, "maxScale": 1.7976931348623157E308, "spatialReference": "NAD_1983_UTM_Zone_19N", "accessInformation": "Maine Department of Environmental Protection with project support and contract administration by Casco Bay Estuary Partnership", "licenseInfo": "Users must assume responsibility in determining the usability of this data for their purposes.
