Fimbristylis castanea - Schoenoplectus pungens Seasonally Flooded Herbaceous Alliance

Description:
Wetlands dominated or codominated by Fimbristylis castanea that often occur in interdune 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. Documented from Assateague National Seashore, 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 rostellata, Phragmites australis, Pluchea foetida, Juncus scirpoides, Hydrocotyle umbellata, Eleocharis parvula, Panicum amarum var. amarulum, Fimbristylis autumnalis, Sabatia stellaris, Ptilimnium capillaceum, and Juncus canadensis. Diagnostic species are Schoenoplectus pungens, Fimbristylis castanea, Eleocharis spp., and Juncus spp. There is usually standing water present in these swales in the spring. In Florida, these are early successional, interdune swales which are dominated by Fimbristylis castanea, sometimes monospecific, sometimes intermixed with Triglochin striata, Sesuvium portulacastrum, and Lilaeopsis carolinensis.
