CEGL007040 Sabal palmetto - Quercus virginiana Swamp Forest

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Cabbage Palmetto - Live Oak Swamp Forest

Colloquial Name: Palmetto - Live Oak Hydric Hammock

Hierarchy Level:  Association

Type Concept: These wet palmetto - live oak forests occur throughout central and southern Florida, and are sometimes known as low hammocks or hydric hammocks. At increasingly smaller scales, this or related vegetation range as far north as southern North Carolina. Sabal palmetto and Quercus virginiana generally share canopy dominance, and few other trees except Juniperus virginiana var. silicicola are commonly encountered. Sabal palmetto or the other two primary canopy species may strongly dominate local patches. Morella cerifera is a typical shrub or small tree. Some related vegetation includes more diverse-canopied hydric hammocks, occurring in more inland situations (or at least away from immediate coastal influence) and with enough admixture of deciduous and tardily deciduous trees to be placed in a mixed forest subclass. This vegetation generally occurs on sands, shell hash, or limestone, with either a substantial calcareous component or influence (past or present) of brackish water. Occurrences in North Carolina and South Carolina are of small size and are marginally attributable to this alliance, where they occur only as small inclusions in, or adjacent to, upland maritime forests.

Classification Comments: This association needs to be compared to other types in ~Sabal palmetto - Quercus virginiana - Magnolia virginiana Swamp Forest Alliance (A3350)$$. Some related vegetation includes more diverse-canopied hydric hammocks, occurring in more inland situations (or at least away from immediate coastal influence) and with enough admixture of deciduous and tardily deciduous trees to be placed in a mixed forest subclass.

Floristics: Sabal palmetto and Quercus virginiana generally share canopy dominance, and few other trees except Juniperus virginiana var. silicicola are commonly encountered. Sabal palmetto or the other two primary canopy species (Quercus virginiana or Juniperus virginiana var. silicicola) may strongly dominate local patches. Morella cerifera is a typical shrub or small tree. Sapindus saponaria can be a shrub and subcanopy codominant on limestone in the Florida peninsula. An example attributed to this type on Ocala National Forest (Rocky Point) was dominated by Quercus virginiana and Sabal palmetto with some Carya aquatica and Celtis laevigata (NatureServe Ecology unpubl. data). Sabal palmetto and Sapindus saponaria are important in the subcanopy and shrub strata; other shrubs present are Sabal minor, Morus rubra, Callicarpa americana, Sageretia minutiflora, Sideroxylon reclinatum, Juniperus virginiana var. silicicola, and Persea palustris. Herbs are dominated by Oplismenus hirtellus ssp. setarius. Vines are common, including Campsis radicans, Parthenocissus quinquefolia, Smilax bona-nox, Toxicodendron radicans, Smilax auriculata, Cocculus carolinus, Matelea gonocarpos, and Gelsemium sempervirens. Epiphytes are dominated by Tillandsia usneoides, with Tillandsia recurvata and Pleopeltis polypodioides ssp. michauxiana (= Polypodium polypodioides var. michauxianum).

Dynamics:  These forests are subject to flooding associated with hurricanes.

Environmental Description:  This vegetation generally occurs on sands, shell hash, or limestone, with either a substantial calcareous component or influence (past or present) of brackish water.

Geographic Range: These wet palmetto - live oak forests occur throughout central and southern Florida; at increasingly smaller scales, this or related vegetation range as far north as southern North Carolina.
