CEGL007141 Pinus palustris / Quercus minima / Aristida beyrichiana - Carphephorus odoratissimus Woodland
Type Concept Sentence: This subxeric community, with mesic flatwoods affinities, occurs in the Apalachicola Embayment region of the Florida Panhandle. The canopy is dominated by Pinus palustris, and the midstory is strongly dominated by Quercus laevis, but Quercus incana and Quercus hemisphaerica may also be present. The subshrub ground cover is remarkable in its mixture of typically sandhill and flatwoods species.
Common (Translated Scientific) Name: Longleaf Pine / Dwarf Live Oak / Beyrich''s Three-awn - Vanilla-leaf Woodland
Colloquial Name: Florida Panhandle Lowlands Subxeric Longleaf Pine Woodland
Hierarchy Level: Association
Type Concept: This subxeric community occurs in the Apalachicola Embayment region of the Florida Panhandle lowlands physiographic province, east of the Apalachicola River. Generalizations regarding soil types are difficult, as this association inhabits Entisols, Ultisols, and Spodosols. However, deposits are all of Pleistocene origin. Soils are typically moderately well-drained and located on low rises embedded in large landscapes of mesic flatwoods. This association has strong mesic flatwoods affinities, which is not surprising considering its landscape context. Pinus palustris is the canopy dominant; the midstory is strongly dominated by Quercus laevis, but Quercus incana, and Quercus hemisphaerica may also be present. The subshrub ground cover is remarkable in its mixture of typically sandhill and flatwoods species; Licania michauxii (typical of sandhills) co-occurs with an assortment of flatwoods subshrubs, including Gaylussacia dumosa, Ilex glabra, Serenoa repens, Vaccinium myrsinites, Morella cerifera, and Quercus minima. The herbaceous layer is dominated by Aristida beyrichiana. Herbaceous indicators include several species typical of mesic flatwoods, such as Carphephorus odoratissimus, Mimosa microphylla, and Symphyotrichum adnatum.
Diagnostic Characteristics: The type is transitional between mesic flatwoods and low rise sandhills, and hence contains a distinctive mix of sandhill and flatwood species in both the midstory and herbaceous layers.
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Concept and description are based on 20 plots from the Carolina Vegetation Survey (http://vegbank.org/cite/VB.ds.199706). As this type represents slightly siltier sites than other associations in this alliance, the association borders on ~Dry-Mesic Loamy Longleaf Pine Woodland Group (G009)$$, and has overlap with both XU2 (Panhandle Xeric Sandhills) and SU2 (Panhandle Silty Longleaf Woodlands) of Carr et al. (2010). ~Pinus palustris / Quercus laevis / Serenoa repens - Clinopodium coccineum Woodland (CEGL003601)$$ described from the De Soto National Forest of southern Mississippi has been asserted to occur in the Apalachicola National Forest, but analysis associates this plot with this type (CEGL007141). It should be determined if CEGL003601 only occurs in southern Mississippi and Alabama.

Floristics: Pinus palustris is the canopy dominant; the midstory is strongly dominated by Quercus laevis, but Quercus incana and Quercus hemisphaerica may also be present. The subshrub ground cover is remarkable in its mixture of typically sandhill and flatwoods species; Licania michauxii (typical of sandhills) co-occurs with an assortment of flatwoods subshrubs, including Gaylussacia dumosa, Ilex glabra, Serenoa repens, Vaccinium myrsinites, Morella cerifera (= Myrica cerifera var. pumila), and Quercus minima. The herbaceous layer is dominated by Aristida beyrichiana. Herbaceous indicators include several species typical of mesic flatwoods, such as Carphephorus odoratissimus, Mimosa microphylla, and Symphyotrichum adnatum. Species with distributions restricted to the central panhandle are also indicators of this association, including Baptisia simplicifolia, Angelica dentata, and Euphorbia exserta. Other common species include Asimina sp., Chrysopsis mariana, Pityopsis aspera, Pteridium aquilinum, and Schizachyrium scoparium.
Dynamics: No Data Available
Environmental Description: Generalizations regarding soil types are difficult, as this association inhabits Entisols, Ultisols, and Spodosols. However, sites are typically moderately well-drained and located on low rises embedded in large flat landscapes of mesic flatwoods. It is likely that these rises are small sandy ridges of marine depositional origin. Subsurface silt content in this type is the highest of any of the Florida associations in ~Xeric Longleaf Pine Woodland Group (G154)$$.
Geographic Range: This subxeric community occurs in the Apalachicola Embayment region of the Florida Panhandle lowlands physiographic province, east of the Apalachicola River. This has been documented from several counties in the central and eastern panhandle, including Leon, Liberty, and Wakulla counties, Florida.
