A3694 Clinopodium arkansanum - Campanula rotundifolia Limestone Lakeshore Alliance

Type Concept Sentence: This alliance is characterized by sparse vegetation of shores of the Great Lakes. The substrate chemistry has high base status and ranges from bedrock to gravel. Characteristic species include Clinopodium arkansanum, Campanula rotundifolia, and Juncus arcticus ssp. littoralis; Populus balsamifera is occasionally present.


Common (Translated Scientific) Name: Limestone Calamint - Bluebell Bellflower Limestone Lakeshore Alliance

Colloquial Name: Great Lakes Limestone Rocky Shore

Hierarchy Level:  Alliance

Type Concept: This alliance is characterized by sparse vegetation of shores of the Great Lakes. The substrate chemistry has high base status and ranges from bedrock to gravel. Characteristic species include Clinopodium arkansanum, Campanula rotundifolia, and Juncus arcticus ssp. littoralis; Populus balsamifera is occasionally present.

Diagnostic Characteristics: Limestone bedrock or gravel of large lakeshores; presence of Clinopodium arkansanum, Campanula rotundifolia, Juncus arcticus ssp. littoralis, and Populus balsamifera are characteristic.

Rationale for Nominal Species or Physiognomic Features: No Data Available

Classification Comments: This alliance requires additional data to characterize with higher confidence. Vegetation of similar environments also occurs on Lake Champlain, but as yet is undescribed in the USNVC.

Similar NVC Types: No Data Available
note: No Data Available

Physiognomy and Structure: This alliance is characterized by sparse vegetation generally dominated by forbs and graminoids; scattered shrubs and trees occur with greater density farther from the lakeshore.

Floristics: Characteristic species include Clinopodium arkansanum, Campanula rotundifolia, and Juncus arcticus ssp. littoralis (= Juncus balticus); Populus balsamifera is occasionally present.

Dynamics:  Wave action and ice-scour structure the vegetation closest to the water, preventing long-term establishment of woody species and forbs, which are confined to cracks in the bedrock.

Environmental Description:  The substrate is limestone bedrock or cobble with high base status.

Geographic Range: This alliance occurs on the Great Lakes.
