Live Oak / Farkleberry - Yaupon ForestElement Identifiers NVCS association: Quercus virginiana / Vaccinium arboreum - Ilex vomitoria Forest Database Code: CEGL007028 Formation: Lowland temperate seasonal evergreen forest Alliance: QUERCUS VIRGINIANA - (SABAL PALMETTO) FOREST ALLIANCE (I.A.4.N.a.4) Element Concept Summary: Dry hammocks, sometimes with Juniperus virginiana var. silicicola present in the canopy. Frequently small Cladina - Cladonia-dominated openings are present. Other characteristic species include Scleria triglomerata, Paronychia baldwinii, Cladina evansii, Stipulicida setacea, and Hypericum hypericoides. Environment: See Summary Vegetation: See Summary Dynamics: See Summary Similar Associations: No information Synonymy: Xeric Hammock Forest, Sandhill Hammock subtype (FNAI 1992b) B. in part Comments: This community is highly variable in expression; the physiognomy can vary locally to woodland, and the height is occasionally stunted enough to approach or reach shrubland, but all are placed here. Its total distribution is not well known. Conservation Ranking & Rare Species GRank: G2G3 (01-01-31): This xeric hammock community occurs in scattered locations from North Carolina south to Florida. In the northern part of its distribution it is confined to near-coastal situations, but extends further inland in Georgia and Florida. This community occurs in completely or largely fire-sheltered situations, yet features xeric species usually associated with fire-maintained pinelands. Occurrences are small, and many are impacted by off-road vehicles and trash dumping. More information is needed on the circumscription and extent of this community type.

These forests are dominated by Quercus geminata with Sabal etonia as an important shrub. Other characteristic species include Quercus myrtifolia, Serenoa repens, Lyonia ferruginea, Garberia heterophylla, Vaccinium stamineum, Cladina evansii, and Morella cerifera (= Myrica cerifera). Lichens are also important. Environment: This association occurs on xeric hammocks of Florida's Lake Wales Ridge on deep coarse sands. These evergreen forests form fire-sheltered sites called oak domes. Vegetation: These forests are dominated by Quercus geminata with Sabal etonia as an important shrub. Other characteristic species include Quercus myrtifolia, Serenoa repens, Osmanthus americanus, Lyonia ferruginea, Garberia heterophylla, Vaccinium stamineum, and Morella cerifera (= Myrica cerifera). Additional shrubs are Quercus laevis, Quercus chapmanii, Rhus copallinum, Vaccinium myrsinites, Lyonia lucida, Vaccinium darrowii, Pinus clausa, Pinus elliottii, Gaylussacia dumosa, Gaylussacia nana, Vaccinium arboreum, Persea humilis, Ilex opaca var. arenicola (= Ilex arenicola), and Pinus palustris. Herbaceous cover is very low; species include Galactia elliottii, Aristida beyrichiana, Liatris tenuifolia, Stillingia sylvatica, Rhynchospora megalocarpa, Tragia urens, Solidago odora, Smilax pumila, and Pteridium aquilinum. Lichens include Cladina evansii, Cladina subtenuis, and Cladonia leporina. Epiphytes Tillandsia usneoides, Tillandsia recurvata, and Tillandsia bartramii also occur. Dynamics: These forests occur on sites which have not burned for decades, or have only burned at low intensity. They occur in patches on the landscape called oak domes. The Quercus geminata leaf litter acts as a firebreak; it is not very combustible. After rain, often the boat-shaped leaves on the ground will contain small amounts of water, further protecting the forest from fire which readily burns the scrub and high pine.
