The U.S. National
Vegetation Classification
Type Concept Sentence: This graminoid marsh occurs in coastal interdunal wetlands and coastal prairies, which are not tidal and are dominated by graminoids such as Andropogon glomeratus, Cladium mariscus ssp. jamaicense, Cyperus spp., Eleocharis spp., Fimbristylis castanea, Fuirena scirpoidea, Muhlenbergia filipes, Panicum spp., Rhynchospora colorata, Sagittaria lancifolia, Schoenoplectus pungens, Setaria magna, Spartina bakeri, and Typha domingensis.

Common (Translated Scientific) Name: Marsh Fimbry - Spikerush species - Southern Umbrella-sedge Coastal Interdunal Marsh & Prairie Group
Colloquial Name: Atlantic & Gulf Coastal Interdunal Marsh & Prairie
Hierarchy Level: Group
Type Concept: This group occurs in coastal interdunal swales, interdunal depressions or poorly drained wet coastal flats. These are graminoid-dominated wetlands; dominant graminoid species can include Andropogon brachystachyus, Carex hyalinolepis, Cladium mariscus ssp. jamaicense, Eleocharis elongata, Eleocharis equisetoides, Eleocharis quadrangulata, Fimbristylis caroliniana, Fimbristylis castanea, Fuirena scirpoidea, Leptochloa fusca ssp. fascicularis, Muhlenbergia filipes, Panicum hemitomon, Panicum tenerum, Paspalum vaginatum, Rhynchospora spp., Spartina patens, Schoenoplectus pungens, and Typha domingensis. These are not tidally influenced, but may be subject to salt or brackish water from storm surge events. The vegetation may range from open water or floating-leaved aquatics in the center of the deepest interdunal depressions, to emergent marsh zones in semipermanent water, to shallower drawdown zones with diverse graminoid and forb vegetation. Wet coastal prairie vegetation is found on wet coastal flats and consists of primarily herbaceous wetland vegetation with a relatively thick cover of graminoid herbs.
Diagnostic Characteristics: This group occurs in coastal interdunal swales, interdunal depressions or poorly drained wet coastal flats. These are graminoid-dominated wetlands. These are not tidally influenced, but may be subject to salt or brackish water from storm surge events.

Physiognomy and Structure: These are graminoid-dominated wetlands, but the vegetation may range from open water or floating-leaved aquatics in the center of the deepest interdunal depressions, to emergent marsh zones in semipermanent water, to shallower drawdown zones with diverse graminoid and forb vegetation.
Floristics: These are graminoid-dominated wetlands; dominant graminoid species can include Andropogon brachystachyus, Carex hyalinolepis, Cladium mariscus ssp. jamaicense, Eleocharis elongata, Eleocharis equisetoides, Eleocharis quadrangulata, Fimbristylis caroliniana, Fimbristylis castanea, Fuirena scirpoidea, Leptochloa fusca ssp. fascicularis, Muhlenbergia filipes, Panicum hemitomon, Panicum tenerum, Paspalum vaginatum, Rhynchospora spp., Spartina patens, Schoenoplectus pungens, and Typha domingensis.
Dynamics: These wetlands are not tidally influenced, but may be subject to salt or brackish water from storm surge events. These wetlands are prone to landscape level disturbance from major tropical storms such as hurricanes which cause dune movement, coastal erosion and accretion. In areas where these wetlands are within a developed rather than natural coastal landscape, hurricane-related disturbance is a greater threat (Feagin et al. 2010).
Environmental Description: This group occurs in coastal interdunal swales, interdunal depressions or poorly drained wet coastal flats. These are not tidally influenced, but may be subject to salt or brackish water from storm surge events.
Geographic Range: This group is found in Atlantic and Gulf of Mexico coastal areas from Maryland and Virginia south to Florida and west to Texas and perhaps Tamaulipas, Mexico.
