CEGL006532 Campanula rotundifolia - Packera paupercula - (Aquilegia canadensis) Riverscour Sparse Vegetation
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Bluebell Bellflower - Balsam Groundsel - (Red Columbine) Riverscour Sparse Vegetation
Colloquial Name: Northern Appalachian Calcareous Riverside Outcrop
Hierarchy Level: Association
Type Concept: This sparsely vegetated community is found on outcrops of circumneutral or calcareous rock along rivershores in the northern Appalachian Mountains and perhaps adjacent Canada. Substrates are usually dolomite, limestone, or slate. Most are flooded annually at high water; this helps to maintain open conditions and also provides silt that accumulates in the rock crevices. The annual disturbance pattern of flooding and ice-scour restricts the vegetation to tough crevice-rooting herbs and low shrubs. Total vegetation cover is often less than 20%. Floristic composition can vary considerably, but characteristic species include Campanula rotundifolia, Aquilegia canadensis, Packera paupercula, Allium schoenoprasum var. sibiricum, Carex eburnea, Carex granularis, Erigeron hyssopifolius, Houstonia longifolia, Viola novae-angliae, Lobelia kalmii, Trisetum spicatum, and Dasiphora fruticosa ssp. floribunda. Associated species that are also common in other habitats include Thalictrum pubescens, Solidago bicolor, Antennaria spp., Ionactis linariifolius, Deschampsia cespitosa, Toxicodendron rydbergii, Vaccinium angustifolium, Vaccinium cespitosum, Cornus amomum, and Cornus sericea. Grimmia spp., Tortella tortuosa, and Tortula ruralis are characteristic mosses.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This association encompasses a gradient of substrate pH, from calcareous limestones in upstate New York to more circumneutral slates in New Hampshire and Maine. Floristic differences have not been carefully examined.
