Name: Avicennia germinans / Spartina alterniflora Saline Shrubland Reference: NatureServe Biotics 2019 Description: This distinctive salt marsh/shrubland community of coastal Louisiana, Texas, and Florida occurs in Gulf-fringing areas, mostly flanking large bays, on the protected sides of barrier islands, and on a few islands on the northern edge of the bays. In Louisiana this type reaches its northern range in limited areas in the Deltaic Plain where occasional hard freezes prevent <i>Avicennia</i> from ever attaining the stature of forests or swamps as it does at more southerly latitudes. This type is also very rare in north Florida for the same reason. This community type oscillates over time between an herbaceous-dominated marsh and tidal low shrubland in direct relationship to hard freezes in the coastal salt marsh, and possibly also due to effects of hurricanes. Although freezes top-kill <i>Avicennia</i>, it resprouts and, within a few freeze-free years, it comes to dominate substantial acreages in salt marsh, particularly on some coastal barrier islands (e.g., Raccoon Island) and in far southern salt marshes immediately adjacent to the Gulf or coastal bays. It may attain heights of 3 m (10 feet) or more during long freeze-free intervals. Species richness is characteristically quite low. Common species in addition to the nominal species include <i>Batis maritima, Salicornia depressa, Iva frutescens, Borrichia frutescens</i>, and <i>Distichlis spicata</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:32661-{5B6C8AA3-A60B-4AAC-B12A-D85E33E09A73} Plot-observations of this Community Concept: 0
