Name: Salicornia spp. - Sarcocornia spp. - Spartina spartinae Tidal Flat & Panne Group Reference: NatureServe Biotics 2019 Description: Vegetation of this group occupies tidally-influenced hypersaline areas along the Atlantic Coast and Gulf of Mexico region from the New England states and the Canadian Maritime Provinces, along the southeastern coast and south to northern Mexico. Examples of this vegetation may occur in patches throughout this relatively large range. The southern limit depends on where the temperate-tropical line is set in relation to this division. These irregularly tidally-flooded marshes are generally somewhat hypersaline from evaporation of seawater after storm surges or exceptionally high tides. They vary somewhat locally in expression, but all tend to exhibit low vascular plant diversity, dominated by halophytic species. There are relatively few plant species which are able to occupy these environments. These include various species of the succulent genera <i>Salicornia</i> spp. and <i>Sarcocornia</i> spp., as well as several grasses (which may be stunted), including <i>Distichlis spicata, Spartina alterniflora, Spartina spartinae</i>, and/or <i>Sporobolus virginicus</i>. Some more southerly associations may contain or be dominated by <i>Batis maritima</i>. Common associates include <i>Atriplex</i> spp., <i>Limonium carolinianum, Monanthochloe littoralis, Plantago maritima var. juncoides, Suaeda maritima</i>, and <i>Triglochin maritima</i>. Total vegetative cover is quite variable, from near total absence of vascular plants to a dense cover of vascular and nonvascular plants; however, unlike high marsh <i>Spartina</i> vegetation, pannes do not feature dense <i>Spartina</i> cover. Algal mats are characteristically present, visible even in densely vegetated pannes. In some cases, blue-green algae may contribute significantly more biomass than vascular species.  Accession Code: urn:lsid:vegbank.org:commConcept:39957-{C5F3D4FF-B48B-4B2A-8741-A3F899B99654} Plot-observations of this Community Concept: 0
