Wetland Communities - Buttonwood Flats
Buttonwood Flats are generally forested wetlands. This type of
plant assemblage is related to hypersaline flats as the "flats" are
susceptible to storm wash and subsequent hypersaline soil conditions.
These flats are often inhospitable to most vascular plants. The
photograph below is very near the reference site on No Name Key (see the
Florida Wetland Delineation Manual on our webpage, for more
information about reference sites). Buttonwood flats are often found
(landward) between the red mangrove fringe and (waterward of) tropical
hammock. Buttonwood, saltwort, glasswort, salt grass, seaside dropseed
grass, keys grass, sea oxeyes, christmas berry, sand cordgrass and the
occasional black mangrove are typical.

View of a buttonwood flat on No Name Pine Key, Florida. Woody shrubs
and small trees are primarily buttonwood with black mangrove in the
background, the groundcover is mostly seashore dropseed grass, Keys
grass and saltwort. See reference site in the Florida Wetland
Delineation Manual for a more complete list of plants, hydrologic
indicators and information about the soils. See
illustrated plant ID cards for common plants.
