From sandy beaches along the island's seaward side to salt marshes on the western bay, Assateague hosts a wide variety of vegetative communities. A diverse array of environmental conditions - elevation, the availability of fresh water, distance from the ocean, the movement of sand, storm-driven winds and seas - all work to shape these communities.

The Assateague Island National Seashore vegetation mapping project delivers many geospatial and vegetation data products, including an indepth project report discussing methods and results, which include descriptions to vegetation associations, field keys to vegetation associations, map classification, and map-class descriptions. The suite of products also includes a database of vegetation plots, verification sites, validation sites, and accuracy assessment (AA) sites; digital images of field sites; field data sheets; digital aerial imagery; hardcopy and digital maps; a contingency table listing AA results; and a geodatabase of vegetation and land cover (map layer), field sites (vegetation plots, verification sites, validation sites, and AA sites), aerial imagery index, project boundary, and metadata.


The products of vegetation mapping projects are stored and managed in the National Park Service's Data Store, a repository for documents and publications relating to park resources. From the highlighted items below, click on the type of information you are looking for.
