CEGL003604 Pinus palustris - Pinus clausa / Quercus laevis / Sporobolus junceus Woodland
Type Concept Sentence: This woodland is found in degraded sandhills of Panhandle Florida; stands contain a mixture of Pinus palustris and Pinus clausa in the canopy, with a well-developed midstory of Quercus laevis and other hardwood species, with a well-developed shrub layer and a generally sparse ground layer.
Common (Translated Scientific) Name: Longleaf Pine - Sand Pine / Turkey Oak / Sandhill Dropseed Woodland
Colloquial Name: Florida Panhandle Fire-Suppressed Sandhills Woodland
Hierarchy Level: Association
Type Concept: This vegetation type is found in degraded sandhills of Panhandle Florida. Stands contain a mixture of Pinus palustris and Pinus clausa in the canopy. A well-developed midstory of several hardwood species is usually present, often dominated by Quercus laevis, in addition to a well-developed shrub layer. Herbaceous species are generally sparse, and overall species richness is low when compared to other Pinus palustris communities. This community is apparently the result of past fire suppression and/or soil disturbance, allowing the invasion of the less fire-tolerant Pinus clausa into Pinus palustris sandhills.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This is the Choctawatchee sand pine, Pinus clausa var. immuginata, a variety not recognized as distinct by either Wunderlin (1998) or Kartesz (1999). This type is marginally natural and has been called a "ruderal" type in the past, largely because it is a fire-suppressed condition. However, it is dominated by native pines and has a representative mix of native ground-layer sandhills species.

Physiognomy and Structure: The tree canopy is dominated by native pines, and the subcanopy is typically well-developed with a mix of oak hardwood species.
Floristics: This vegetation type contains a mixture of Pinus palustris and Pinus clausa (= var. immuginata) in the canopy. A well-developed midstory of several hardwood species is usually present, often dominated by Quercus laevis, other documented species include Ilex ambigua, Quercus geminata, Quercus margarettae, and Quercus incana (Rodgers and Provencher 1999). Ilex vomitoria and Gaylussacia dumosa are the dominant shrub species. The most important understory species are Schizachyrium scoparium, Tephrosia mohrii, Dichanthelium spp., Sporobolus junceus, Polygonella gracilis, and Galactia microphylla.
Dynamics: This community is apparently the result of past fire suppression, allowing the invasion of the less fire-tolerant Pinus clausa into Pinus palustris sandhills.
Environmental Description: This vegetation type is found in sandhills of Panhandle Florida. According to Rodgers and Provencher (1999), Pinus clausa has colonized fire-suppressed and soil-altered Pinus palustris uplands of this area (Eglin Air Force Base), especially along the coastal lowlands where Pinus clausa occurs naturally. This type also occurs along the central and eastern parts of Eglin Air Force Base (C. Nordman pers. comm.).
Geographic Range: This vegetation type is found in sandhills of Panhandle Florida.
