These feature classes reside within the BIOLOGY Feature Data Set of the St Marys River - 2021 ESI Geodatabase. It contains vector polygons and points representing BENTHIC data for the Great Lakes St Marys River System. The study area includes the St. Marys River at the southern portion of Lake Superior beginning just east of Monocle Lake and south of Iroquois Island ending to the headwaters of Lake Huron. This data set contains sensitive biological resource data for submerged aquatic vegetation (SAV). Vector polygons and points in these datasets represent SAV. Species-specific abundance, seasonality, status, life history, and source information are stored in associated data tables (described in Entity Attribute Overview below) designed to be used in conjunction with this spatial data layer. This data set is a portion of the ESI data for the Great Lakes St. Marys River System. As a whole, the ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil, and include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources.
