NVCS association: Pinus elliottii var. elliottii / Serenoa repens - Ilex glabra Woodland
Database Code: CEGL003643
Formation: Saturated temperate or subpolar needle-leaved evergreen woodland
Alliance: PINUS ELLIOTTII SATURATED TEMPERATE WOODLAND ALLIANCE (II.A.4.N.f.2)
Element Concept
Summary: This association is currently very broadly defined. It includes flatwoods on Eglin Air Force Base, Osceola National Forest, and Ocala National Forest. Pinus elliottii var. elliottii dominates the generally open canopy. Pinus palustris or Gordonia lasianthus and Pinus serotina can be present, even codominant. The dense shrub stratum consists primarily of Ilex glabra and Serenoa repens.
Environment: Soils in this type of flatwoods range from poorly drained to very poorly drained, fine sandy loams or silt loams, but are typically poorly drained, light-textured, fine sands which are generally acidic, with low organic matter and a spodic horizon which retards drainage. On some sites which tend towards mesic, this association occurs where there has been a lack of growing-season fire.
Vegetation: Pinus elliottii var. elliottii dominates the generally open canopy. Pinus palustris or Gordonia lasianthus and Pinus serotina can be present, even codominant. The dense shrub stratum consists primarily of Ilex glabra and Serenoa repens. Other common shrubs include Persea palustris, Gaylussacia nana, Gaylussacia dumosa, Gaylussacia tomentosa, Photinia pyrifolia (= Aronia arbutifolia), Quercus minima, Ilex coriacea, Vaccinium elliottii, Acer rubrum, Vaccinium formosum, Befaria racemosa, Lyonia ferruginea, Lyonia fruticosa, Morella cerifera, Kalmia hirsuta, Vaccinium myrsinites, and Lyonia lucida. The most common vine is Smilax laurifolia; other vines are Smilax auriculata, Smilax glauca, and Vitis rotundifolia. The herbaceous flora is generally sparse or patchy, including Aristida beyrichiana, Aristida spiciformis, Woodwardia virginica, Pteridium aquilinum, Andropogon glomeratus, Andropogon capillipes, Andropogon virginicus, Sporobolus curtissii, Sporobolus floridanus, Schizachyrium scoparium, Dichanthelium spp., Gratiola hispida, Pityopsis graminifolia, and Xyris spp.
Dynamics: This flatwoods association is typically in areas which have not been subjected to repeated growing-season fire. The dominance of shrubs is generally related to lack of fire, or prescribed fire outside the growing season or lightning season. Many of these sites probably were dominated by Pinus palustris in the past, but are now dominated by Pinus elliottii.
Similar Associations:
Pinus palustris / Serenoa repens - Ilex glabra Woodland (CEGL003653)--has a similar shrub and herbaceous flora but is dominated by Pinus palustris.
Synonymy:

Comments: This community is related to Pinus palustris / Serenoa repens - Ilex glabra Woodland (CEGL003653), which has a similar shrub and herbaceous flora but which is dominated by Pinus palustris. There is a lack of consensus on whether they should be combined.

NVCS association: Pinus serotina / Sporobolus floridanus - Aristida beyrichiana Woodland
Database Code: CEGL003797
Formation: Saturated temperate or subpolar needle-leaved evergreen woodland
Alliance: PINUS SEROTINA SATURATED WOODLAND ALLIANCE (II.A.4.N.f.9)
Element Concept
Summary: These are linear pond pine woodlands occurring along streams in the Florida Panhandle. They are dominated by Pinus serotina with a little Pinus palustris over Sporobolus floridanus, Aristida beyrichiana, Lyonia mariana, Arundinaria gigantea ssp. tecta (= Arundinaria tecta), and Lyonia lucida. These woodlands are floristically diverse; 55 taxa were found in 0.1-ha plot.
Environment: This community occurs between longleaf pine flatwoods and stream baygall thickets.

Smilax laurifolia is the only vine found in the plot.
Dynamics: These woodlands are prone to fire spreading downslope from adjacent longleaf pine flatwoods. Fire probably has occurred less frequently than the longleaf pine flatwoods, but at higher intensity.
