CEGL004765 Rhizophora mangle Overwash Island Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Red Mangrove Overwash Island Forest
Colloquial Name: Overwash Island Red Mangrove Forest
Hierarchy Level: Association
Type Concept: These are mangrove forests dominated by Rhizophora mangle (monospecific), in mangrove island situations, with no adjacent (non-tidal) upland area. These communities are the floristically simplest and most strictly monodominant of red mangrove communities. Rhizophora individuals are relatively short, with average forest height of 6-7 m and average dbh of about 11 cm. In addition, Gilmore and Snedaker (1993) state that "In just about all ecological aspects, the overwash mangrove island type is equivalent to the fringe forest mainly because of the relatively high frequency of tidal inundation. The principal difference, however, lies in the fact that tidal waters completely overwash the island on almost every tidal cycle. Although tidal overwash also occurs on the retreating or falling tides, the water is not necessarily the same parcel that entered due to the mixing and exchange that take place on the inland water side of the island. Likewise, in the case of strong littoral circulation, the overwash approximates a unidirectional flow. Also the presence of a berm or wrack line is seldom observed. An interesting aspect of overwash islands ... is the high incidence of bird rookeries. Presumably this is mainly due to the island effect, which provides a water barrier to potential terrestrially based predators and scavengers."

Floristics: These are mangrove forests dominated by Rhizophora mangle (stands are typically monospecific). These communities are the floristically simplest and most strictly monodominant of red mangrove communities. Rhizophora individuals are relatively short, with average forest height of 6-7 m and average dbh of about 11 cm. (Gilmore and Snedaker 1993).

Environmental Description: These mangrove forests are found in mangrove island situations, with no adjacent (non-tidal) upland area. These communities are the floristically simplest and most strictly monodominant of red mangrove communities (Gilmore and Snedaker 1993).
Geographic Range: In the United States, this type would be restricted to the Florida Keys and extreme southern peninsular Florida. It presumably also occurs in the Caribbean.
