CEGL003947 Chrysoma pauciflosculosa - Paronychia erecta Dwarf-shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Woody-goldenrod - Square-flower Dwarf-shrubland
Colloquial Name: Florida Panhandle Woody-goldenrod Dune Dwarf-shrubland
Hierarchy Level: Association
Type Concept: This coastal scrub woody-goldenrod dwarf-shrubland is restricted to near-coastal dunes of the Florida Panhandle, Mississippi, and possibly adjacent Alabama. Vegetation is usually strongly dominated by Chrysoma pauciflosculosa, often with a mixture of Paronychia erecta. The short-statured vegetation ranges from fairly dense to open (sometimes less than 25% shrub cover, but all placed here). This type represents a later successional phase of upland dune vegetation in northwest Florida occurring especially in Bay, Escambia, and Okaloosa counties, but also found in Franklin and Gulf counties, and in some areas of southern Mississippi. More chronically or recently disturbed dunes support communities dominated by herbaceous species, and later successional dunes are dominated by Ceratiola ericoides. Other characteristic species include Galactia microphylla (within its range), Polygonella gracilis, Polygonella polygama, and Schizachyrium maritimum. Cladonia leporina is a typical lichen component.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Paronychia erecta was added as a nominal to better reflect the composition of this type in Florida (Johnson 1997, A. Johnson pers. comm.). See Johnson and Muller (1993a) and Johnson et al. (1992a). Estimated extent of about 3700 acres remaining in Florida. Examples are known from Dog Island and the St. Joseph Peninsula; protected examples are known from Grayton Beach and Henderson State Parks, as well as from Department of Defense lands. These include Shell and Crooked islands (Tyndall Air Force Base) and Santa Rosa (Eglin Air Force Base).
This type grades into at least two earlier successional phases of dune vegetation, ~Uniola paniculata - Panicum amarum var. amarulum - Iva imbricata Grassland (CEGL004041)$$ and ~Schizachyrium maritimum - (Heterotheca subaxillaris) Grassland (CEGL004057)$$, both of which have been exposed to more recent sand burial.

Floristics: Vegetation is usually strongly dominated by Chrysoma pauciflosculosa, often with a mixture of Paronychia erecta. The short-statured vegetation ranges from fairly dense to open (sometimes less than 25% shrub cover, but all placed here). Other characteristic species include Galactia microphylla (within its range), Polygonella gracilis, and Schizachyrium maritimum. Cladonia leporina is a typical lichen component. Additional plant species found in this community type include low amounts of Uniola paniculata and Schizachyrium maritimum, as well as Smilax auriculata, Paronychia erecta, and Polygonella polygama (Johnson 1997).
Dynamics: No Data Available
Environmental Description: According to Johnson (1997) this community occupies dune ridges which have been protected from sand burial for 18-23 years. More chronically or recently disturbed dunes support communities dominated by some combination of Uniola paniculata, Panicum amarum var. amarulum, and Schizachyrium maritimum, while later successional dunes are dominated by Ceratiola ericoides.
