Wetland Evaluation and Delineation Program

Wetland Communities - Hypersaline Flats and Salterns

SalternsHypersaline Flats and Salterns are WETLANDS created from marine overwash that evaporates to create a high salt content in the soil that effectively limits the growth of most vascular plant species. There are many variations of this community and classic examples in the Florida Keys and south Florida will include the following plants: black mangrove, saltwort, glasswort, salt grass, seaside dropseed grass, keys grass, sea oxeyes, christmas berry, sand cordgrass and sea-purslane.

To the right is a view of a hypersaline flat on Big Pine Key, Florida.
