Sand Laurel Oak - Pignut Hickory - Southern Magnolia / Scrub Palmetto Forest


Element Identifiers

NVCS association: Quercus hemisphaerica - Carya glabra - Magnolia grandiflora / Sabal etonia Forest

Database Code: CEGL003792

Formation: Mixed broad-leaved evergreen - cold-deciduous forest

Alliance: QUERCUS HEMISPHAERICA - CARYA GLABRA FOREST ALLIANCE (I.C.2.N.a.5)

Element Concept

Summary: These are dry-mesic to xeric hammocks of central Florida. These well-developed xeric forests are dominated by Quercus hemisphaerica, Carya glabra, and Magnolia grandiflora in the canopy, and Magnolia grandiflora and Carya glabra in the understory. This association includes what would be considered beech-magnolia forests, south of the range of Fagus grandifolia. Sabal etonia and Serenoa repens are important shrub components.

Environment: These forests occur on slopes associated with sinks and river and creek bluffs.

Vegetation: These well-developed xeric forests are dominated by Quercus hemisphaerica, Carya glabra, and Magnolia grandiflora in the canopy, and Magnolia grandiflora and Carya glabra in the understory. Other canopy or subcanopy trees include Quercus virginiana, Sabal palmetto, Osmanthus americanus, Quercus nigra, Persea borbonia, and Ilex opaca. Sabal etonia and Serenoa repens are important shrub components. Other shrubs are Osmanthus americanus, Vaccinium stamineum, Callicarpa americana, Lyonia ferruginea, Lyonia fruticosa, Quercus chapmanii, Zamia pumila, Prunus angustifolia, Prunus caroliniana, Asimina obovata, Sideroxylon lanuginosum, Rhapidophyllum hystrix, Vaccinium arboreum, Persea humilis, Diospyros virginiana, and Ilex opaca. Vines include Smilax glauca, Vitis rotundifolia, Smilax pumila, Smilax bona-nox, Smilax tamnoides (= Smilax hispida), Gelsemium sempervirens, and Parthenocissus quinquefolia. Epiphytes include Tillandsia usneoides, Tillandsia bartramii, Tillandsia recurvata, and Pleopeltis polypodioides ssp. michauxiana. The herbaceous flora includes Rhynchospora megalocarpa, Mitchella repens, Dichanthelium spp., Triphora trianthophora, Scleria triglomerata, Oplismenus hirtellus ssp. setarius, Elephantopus elatus, Galium tinctorium, Cyperus retrorsus, and Panicum sp.

Dynamics: These forests are protected from fire on slopes.

Myrtle Oak - Sand Live Oak - Chapman Oak Shrubland


Element Identifiers

NVCS association: Quercus myrtifolia - Quercus geminata - Quercus chapmanii Shrubland

Database Code: CEGL003825

Formation: Sclerophyllous temperate broad-leaved evergreen shrubland

Alliance: QUERCUS GEMINATA - QUERCUS MYRTIFOLIA - QUERCUS CHAPMANII SHRUBLAND ALLIANCE (III.A.2.N.c.26)

Element Concept

Summary: This shrubland is a xeromorphic shrubby community consisting of evergreen scrub oaks (Quercus myrtifolia, Quercus chapmanii, Quercus geminata), Lyonia ferruginea, and other species, many with restricted distributions, such as Ceratiola ericoides and Serenoa repens. The herb layer is generally sparse and frequently dominated by lichens (Cladonia leporina, Cladonia prostrata, Cladina evansii, and Cladina subtenuis). The white or light-colored sandy soils are extremely well-drained and infertile. Oak scrub is pyrogenic with typical fire frequencies of 10-50 years, depending on fuel availability and ignition sources (Austin 1976, Myers 1990, The Nature Conservancy 1992). This community type occurs in the northern Florida panhandle, the northern to central peninsula, on Floyds Island in the Okefenokee, and possibly into southwestern Alabama. This is the more northern-central scrub oak community in Florida.

Conservation Ranking & Rare Species

GRank: G3 (01-01-31): This community type occurs in the northern Florida panhandle, the northern to central peninsula, on Floyds Island in the Okefenokee, and possibly into southwestern Alabama. Acreage is limited and known occurrences are small. Additionally, this community is maintained by a combination of extreme edaphic conditions (droughty sands and high summer temperatures) and periodic fire. Fire has generally been suppressed, altering and degrading occurrences of this community type.

High-ranked species: BONAMIA GRANDIFLORA (G3), APHELOCOMA COERULESCENS (G3)
