Name: Bursera simaruba - Coccoloba diversifolia - Eugenia axillaris Forest Group Reference: NatureServe Biotics 2019 Description: In the U.S., this hardwood hammock forest group occurs in southern Florida, on rockland sites. It consists of upland hardwood forest on elevated ridges of limestone in three discrete regions: the Florida Keys, southeastern Big Cypress, and the Miami Rock Ridge. Tropical hardwood species likely to be encountered throughout are <i>Bursera simaruba, Coccoloba diversifolia</i>, and <i>Eugenia axillaris</i>. The northward ranges of these species are limited by the incidence of frosts. These forests tend to have a dense canopy that produces deeper shade, less evaporation, and lower air temperature than surrounding vegetation. This microclimate, in combination with high water tables, tends to keep humidity levels high and the community quite mesic. A number of orchid and bromeliad species thrive in such conditions. Unlike most coastal plain systems, fire is a major threat to these hardwood hammock forests.<br /><br />In the U.S., this group also occurs as a narrow band of hardwood forest and tall shrublands lying just inland of the coastal dune system in south Florida. It is found on stabilized, old, coastal dunes, often with substantial shell components. The vegetation is characterized by hardwood species with tropical affinities. As such, the northern extent of this group is limited by periodic freezes and cold-tolerance of tropical constituent species, such as <i>Piscidia piscipula, Guapira discolor, Exothea paniculata</i>, and <i>Eugenia axillaris</i>. These stands are closely related to the rockland based tropical hammocks.  Accession Code: urn:lsid:vegbank.org:commConcept:40346-{4BC543E4-4E6C-4306-9FD2-B993172C0699} Plot-observations of this Community Concept: 0
