Translated Name:Marsh Fimbry - Common Threesquare Coastal Marsh Alliance
Colloquial Name:Southeastern Fimbry Coastal Marsh
These wetlands of southeastern coastal areas from Delaware to Texas are dominated or codominated by Fimbristylis castanea and Schoenoplectus pungens which often occur in interdune swales. Diagnostic species are Eleocharis spp., Fimbristylis castanea, Juncus spp., and Schoenoplectus pungens and Spartina patens (in interdunal swales). The general aspect and species composition of this vegetation are variable, not only among occurrences, but also over the course of the growing season. When Schoenoplectus pungens is not dense, it is most often associated with an even mixture of Spartina patens or Fimbristylis castanea. Other herbs are sparse and contribute very little to the overall vegetative cover. There is usually standing water present in these swales in the spring.
Wetlands dominated or codominated by Fimbristylis castanea that often occur in interdune swales. Vegetation may be characterized by dense Schoenoplectus pungens or an even mixture of Spartina patens or Fimbristylis castanea. In spring, Schoenoplectus pungens is generally dominant. Diagnostic species are Eleocharis spp., Fimbristylis castanea, Juncus spp. and Schoenoplectus pungens.

These are graminoid herb dominated wetlands.
This alliance includes wetlands dominated or codominated by Fimbristylis castanea or Schoenoplectus pungens that often occur in interdune swales on the southeastern coast, from Delaware to Florida. This alliance is documented from Assateague Island National Seashore (Higgins et al. 1971, Hill 1986), where it is typically characterized by dense Schoenoplectus pungens (= Scirpus pungens) (up to 80% cover). When Schoenoplectus pungens is not as dense, it is most often associated with an even mixture of Spartina patens or Fimbristylis castanea. In spring, Schoenoplectus pungens is generally dominant with few other associates except Eleocharis spp., imparting a distinct aerial photo-signature. By late summer a number of other species, such as Fimbristylis castanea and Sabatia stellaris, contribute more substantial cover. Other herbs are sparse and contribute very little to the overall vegetative cover. These associated species include Andropogon virginicus, Eleocharis parvula, Eleocharis rostellata, Fimbristylis autumnalis, Hydrocotyle umbellata, Juncus canadensis, Juncus scirpoides, Panicum amarum var. amarulum, Phragmites australis, Pluchea foetida, Ptilimnium capillaceum, and Sabatia stellaris. Diagnostic species are Eleocharis spp., Fimbristylis castanea, Juncus spp. and Schoenoplectus pungens. There is usually standing water present in these swales in the spring. In Florida, these are early-successional, interdunal swales which are dominated by Fimbristylis castanea, sometimes monospecific, sometimes intermixed with Triglochin striata, Sesuvium portulacastrum, and Lilaeopsis carolinensis.
These wetlands often occur in interdunal swales. There is usually standing water present in these swales in the spring.
Low
This vegetation occurs in southern coastal interdunal swales. These sites are not subject to regular tides, but may be exposed to saltwater from storm surges and seasonal high tides. High wind and storm surges can alter the position of dunes and swales. These are dynamic landforms which change as part of natural coastal processes.

About spatial standards:
The United States Federal Geographic Data Committee (hereafter called the FGDC) is tasked to develop geospatial data standards that will enable sharing of spatial data among producers and users and support the growing National Spatial Data Infrastructure (NSDI), acting under the Office of Management Budget (OMB) Circular A-16 (OMB 1990, 2000) and Executive Order #12906 (Clinton 1994) as amended by Executive Order #13286 (Bush 2003). FGDC subcommittees and working groups, in consultation and cooperation with state, local, tribal, private, academic, and international communities, develop standards for the content, quality, and transferability of geospatial data. FGDC standards are developed through a structured process, integrated with one another to the extent possible, supportable by the current vendor community (but are independent of specific technologies), and publicly available.

About this document
This document contains type descriptions at the Alliance level of the U.S. National Vegetation Classification. These descriptions were primarily written by NatureServe ecologists in collaboration with Federal Geographic Data Committee Vegetation Subcommittee and a wide variety of state, federal and private partners as a part of the implementation of the National Vegetation Classification. Formation descriptions were written by the Hierarchy Revisions Working Group. The descriptions are based on consultation with natural resource professionals, published literature, and other vegetation classification systems. The Ecological Society of America's Panel on Vegetation Classification is responsible for managing the review and formal adoption of these types into the National Vegetation Classification. Partners involved in the implementation of the USNVC include:

Given the dynamic nature of the standard, it is possible a type description is incomplete or in revision at the time of download; therefore, users of the data should track the date of access and read the revisions section of the USNVC.org website to understand the current status of the classification. While USNVC data have undergone substantial review prior to posting, it is possible that some errors or inaccuracies have remained undetected.
