No image for this habitat.
Habitat Overview Includes all herb-dominated habitats on barrier islands, from the foredunes to the edge of the marshes and wet flats on the sound side of the islands.

The plants are all psammophytic and tolerant of salt spray. Some occur only on the most xeric and exposed portions of the dunes, others are associated with more mesic and more sheltered swales.

Insects are obligate herbivores on the dune plants, or are believed to be so -- for some, the host plants have not yet been determined, but the species appear to be highly restricted to barrier island dunes.
