CEGL002303 Igneous - Metamorphic Cobble - Gravel Inland Lake Shore Sparse Vegetation

Type Concept Sentence: No Data Available

Common (Translated Scientific) Name: Igneous - Metamorphic Cobble - Gravel Inland Lake Shore Sparse Vegetation

Colloquial Name: Inland Lake Igneous - Metamorphic Cobble - Gravel Shore

Hierarchy Level:  Association

Type Concept: This igneous - metamorphic cobble - gravel inland lakeshore community type is possibly found on small lakes on the Canadian shield in the Upper Great Lakes region of the United States and Canada, and perhaps more widely in Canada. Stands are exposed bedrock along lakeshores. Cobble-gravel substrate may be either granite/metamorphic or basalt/conglomerate (?). Vegetation is sparse, but little information is available to further characterize this type.

Diagnostic Characteristics: No Data Available

Rationale for Nominal Species or Physiognomic Features: No Data Available

Classification Comments: This type may only occur on larger inland lakes where sufficient wave action exists to create a sparsely vegetated shoreline. The type needs to be further studied, and contrasted with Great Lakes types of either granite/metamorphic substrates, ~Non-alkaline Cobble - Gravel Great Lakes Shore Sparse Vegetation (CEGL002508)$$, or basalt/conglomerate substrates, ~Basalt - Diabase Cobble - Gravel Great Lakes Shore Sparse Vegetation (CEGL005250)$$.

note: No Data Available
Physiognomy and Structure: No Data Available

Floristics: Vegetation is sparse, but little information is available to further characterize this type.

Dynamics:  A sufficiently sized lake with substantial wave action is needed to create a sparse, rocky vegetation zone along the lakeshore.
Environmental Description:  Stands are exposed bedrock along lakeshores. Cobble - gravel substrate may be either granite/metamorphic or basalt/conglomerate (?).
Geographic Range: This cobble-gravel lakeshore community type is possibly found on small lakes on the Canadian shield in the Upper Great Lakes region of the United States and Canada, and perhaps more widely in Canada, ranging from Michigan and Minnesota to Ontario and probably more widely across central Canada.
