Layer: Percent Hardbottom (ID: 122)

Parent Layer: Northeast Ecological Corridor Reserve, Puerto Rico (2014)

Name: Percent Hardbottom

Display Field: P_HARD

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Percent Hardbottom refers to the amount (i.e., patchiness) of hardbottom structure within a habitat polygon. Polygons with discontinuous cover of hard bottom with areas of interspersed unconsolidated sediments that were too small to be mapped as a different feature (i.e., smaller than the minimum mapping unit, 100m²) were classified as 0%-10%, 10%-30%, 30%-50%, 50%-70%, and 70%-90% hardbottom. Polygons that were estimated to have continuous cover of hardbottom were classified as 90%-100%, while polygons with less than 10% hardbottom were classified as 0%-10% (unconsolidated sediments). This modifier was determined by estimating the percent hardbottom at the scale of the polygon by analyzing remotely sensed imagery and underwater videos.
