Display Field: regunitid

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Cladophora is a native green algae that typically grows on hard substrate in shallow waters. It can become a nuisance when it detaches from the bottom and washes onto shore where it can foul beaches and water intakes. In the Overall Assessment of Nearshore Waters, Cladophora is assessed by calculating the percent of the total mapped area classified as submerged aquatic vegetation (SAV) in a 2016-2018 satellite-derived product from Michigan Tech Research Institute(MTRI)."Cladophora" are the areas classified as SAV in the MTRI mapping product, and likely to be Cladophora given the habitat characteristics (hard substrate, shallow waters)."Uncolonized substrate" are the areas where no SAV was detected in the MTRI mapping product. Cladophora is not assessed in Regional Units lacking hard substrate and with limited light availability, and in areas with coastal wetlands as the SAV in these areas may be wetland-associated vegetation and not nuisance Cladophora.For more information on the MTRI SAV mapping product, see https://mtri.org/cladophora.html. Low Stress: <20% coverage; Moderate Stress: 20-35% coverage; High Stress: >35% coverage
