Description:
This association represents tidally flooded hypersaline flats or very shallow depressions (pannes) dominated by halophytic herbs, including Salicornia virginica, Salicornia bigelovii, Salicornia maritima, and stunted Spartina alterniflora, that occur along the Atlantic coast. Vegetation of this association tends to develop in shallow depressions within high salt marshes where drainage is poor. The depressions are flooded by high tides, but as the water evaporates during low tide, the salinity concentration increases forming 'salt pannes.' Formation of the pannes may result from ice scouring, rafting flotsam, peat compaction, mosquito ditch levees, or erosion of tidal creek banks, which create small, sparsely vegetated to unvegetated impoundments. Pannes form in both high and low salt marsh habitats; this community is regularly to irregularly flooded by tides. Bare peat and/or mucky soils are prevalent (up to 85% bare soils). Total vegetative cover is variable in pannes, from near total absence of vascular plants to a dense cover of Salicornia virginica, Salicornia bigelovii, Salicornia maritima, or Spartina alterniflora (short form). Common associates include Limonium carolinianum, Plantago maritima var. juncoides, Triglochin maritima, Suaeda maritima, and Atriplex spp. Algal mats are characteristically present, visible even in densely vegetated pannes. Blue-green algae are an important component of these mats, in some cases contributing significantly more biomass to the community than do vascular species. Diagnostic species include Salicornia bigelovii and Salicornia virginica.
