CEGL004408 Quercus virginiana - Quercus (hemisphaerica, nigra) / Serenoa repens Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Live Oak - (Darlington Oak, Water Oak) / Saw Palmetto Forest
Colloquial Name: Dry Live Oak Hammock
Hierarchy Level: Association
Type Concept: This association represents one of two inland hammocks or oak domes with a dominant or significant canopy component of Quercus virginiana in Florida and adjacent areas. A variant occurs on older, well-developed landscapes of Cumberland Island National Seashore. This type is the more mesic of the two and is characterized by a more diverse overstory that often includes Quercus hemisphaerica and Quercus nigra (more xeric stands with a purer Quercus virginiana overstory are accommodated by ~Quercus virginiana / Vaccinium arboreum - Ilex vomitoria Forest (CEGL007028)$$). Serenoa repens is a typical, and possibly dominant, shrub-layer species. It is believed that this community develops on sites that would have been occupied by Pinus palustris given sufficiently frequent fire-return intervals.

Floristics: Quercus virginiana is frequently the single most important species in the overstory of this forest. The diverse overstory often includes Quercus hemisphaerica, a second important indicator on Cumberland Island National Seashore, and Quercus nigra. Serenoa repens is a typical, and possibly dominant, shrub-layer species. Other canopy trees documented in vegetation plots from the Osceola National Forest include Quercus hemisphaerica, Quercus nigra, and Pinus taeda (NatureServe Ecology unpubl. data). Quercus hemisphaerica is an important indicator on Cumberland Island. The subcanopy includes Juniperus virginiana var. silicicola, Quercus hemisphaerica, Quercus nigra, and Quercus virginiana. Tall shrubs include Morella cerifera, Ilex opaca, Calycanthus floridus, Callicarpa americana, Diospyros virginiana, Persea palustris, and Pinus elliottii. Short shrubs additionally include Vaccinium myrsinites, Serenoa repens, Asimina angustifolia (= Asimina longifolia), Vaccinium stamineum, Magnolia virginiana, Ilex glabra, Ilex vomitoria, Vaccinium arboreum, Acer rubrum, and Quercus hemisphaerica. Herbaceous plants are very sparse and include Aristida beyrichiana, Panicum anceps, Croton michauxii (= Crotonopsis linearis), Eupatorium compositifolium, Cnidoscolus urens var. stimulosus (= Cnidoscolus stimulosus), Andropogon virginicus, and Pterocaulon pycnostachyum (NatureServe Ecology unpubl. data).
Dynamics: This vegetation presumably develops due to lack of fire, which is necessary to perpetuate Pinus palustris vegetation. This type develops naturally in localized areas where fire spread is limited by factors such as proximity to drainages and other factors. Once established this vegetation does not carry fire well, and the hammock may spread outward gradually, even when the surrounding landscape is burned, especially with dormant season fires.
Environmental Description: This vegetation occurs on dry sandy uplands in northern Florida and likely in adjacent areas of Georgia. Examples are found on topographically isolated or other fire-infrequent settings.
Geographic Range: This type is known from central and northeastern Florida and adjacent areas of Georgia.
