CEGL003914 Alnus serrulata - Rhododendron arborescens / Sarracenia oreophila - Rhynchospora rariflora Seepage Shrubland

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Hazel Alder - Smooth Azalea / Green Pitcherplant - Few-flower Beaksedge Seepage Shrubland

Colloquial Name: Southern Appalachian Low Mountain Seepage Bog

Hierarchy Level:  Association

Type Concept: This non-alluvial, montane wetland is primarily shrubby, with open herb-dominated areas. Known examples, from Clay County, North Carolina, and Towns County, Georgia, are on shallow slopes, at about 457-550 m (1500-1800 feet) elevation, and have a palustrine hydrology, fed by acidic seepage. Few examples are known and all have been altered considerably by grazing, fire, cultivation, and drainage efforts. Common species in the 1- to 2-m shrub stratum include Alnus serrulata, Rhododendron arborescens, Lyonia ligustrina, Aronia arbutifolia, and Rosa palustris. Osmunda cinnamomea and Sarracenia oreophila are conspicuous and occur as clumps in herbaceous openings. Other typical herb species include Rhynchospora rariflora, Thelypteris palustris var. pubescens, Sagittaria latifolia, Rhexia virginica, Rhexia mariana, Eryngium integrifolium, Helianthus angustifolius, Eupatorium perfoliatum, Eupatorium pilosum, Eupatorium rotundifolium var. ovatum, Eutrochium fistulosum, Eriophorum virginicum, Sanguisorba canadensis, and Juncus caesariensis. Other characteristic species include Andropogon glomeratus, Symphyotrichum dumosum, Betula nigra, Cinna arundinacea, Drosera capillaris, Eleocharis tuberculosa, Eriocaulon decangulare, Eryngium integrifolium, Fuirena squarrosa, Gratiola pilosa, Juncus canadensis, Panicum virgatum, Polygala cruciata, Rhynchospora gracilenta, Scleria muehlenbergii, Saccharum giganteum, Scleria ciliata, and Xyris jupicai. Fire may have been a natural disturbance in this community type, suggested by the large suite of species more typical of fire-maintained communities of the Coastal Plain.

Diagnostic Characteristics: No Data Available

Rationale for Nominal Species or Physiognomic Features: No Data Available

Classification Comments: Similar non-alluvial wetland vegetation occurs in the Piedmont of Georgia and Alabama. These Piedmont bogs lack the mountain species component that distinguishes the community described here. Little is known about these Piedmont wetland communities and their classification is uncertain at this time.

Physiognomy and Structure: No Data Available

Floristics: Owing to disturbance of the only known examples, the original vegetation structure of this community is unknown. This non-alluvial, montane wetland is primarily shrubby, with open, herb-dominated areas. Common species in the 1- to 2-m shrub stratum include Alnus serrulata, Rhododendron arborescens, Lyonia ligustrina, Aronia arbutifolia, and Rosa palustris. Osmunda cinnamomea and Sarracenia oreophila are conspicuous and occur as clumps in herbaceous openings. Other typical herb species include Rhynchospora rariflora, Eriocaulon decangulare, Thelypteris palustris var. pubescens, Sagittaria latifolia (= var. pubescens), Rhexia virginica, Rhexia mariana, Eryngium integrifolium, Helianthus angustifolius, Eupatorium perfoliatum, Eupatorium pilosum, Eupatorium rotundifolium var. ovatum, Eutrochium fistulosum (= Eupatorium fistulosum), Eriophorum virginicum, Sanguisorba canadensis, and Juncus caesariensis.

Dynamics:  Fire may have been a natural disturbance in this community type. This is suggested by the large suite of species more typical of fire-maintained communities of the Coastal Plain. It is also possible that this suite of species is present in this community because of its low elevation and phytogeographic history. Little is known about the successional dynamics of mountain wetlands. It is thought that historically fire was important to maintaining this wetland''s open structure.

Environmental Description:  Known examples are on shallow slopes, at about 457-550 m (1500-1800 feet) elevation, and have a palustrine hydrology, fed by acidic seepage.

Geographic Range: This type is known only from Clay County, North Carolina (Govus 1987), and Towns County, Georgia (Schnell 1980). It should be sought in nearby counties. This community also occurs in Alabama along the Little River.
