Parent Layer: Biological Habitat

Name: Seagrass Survey Areas

Display Field: SurveyArea

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This layer shows seagrass survey schemes and approaches by state. Survey approaches vary based on seagrass mapping program goals and resources, with some states planning annual survey rotations by geographic region, and others taking a more intermittent approach and surveying as time and resources allow. Understanding the specific boundaries of each survey is important, as it helps distinguish between areas where changes in seagrass have been detected and areas that were not surveyed, where changes are unknown. The metadata for this layer provides additional resources and links to more detailed information about how each state or mapping program plans and conducts its seagrass surveys.
