CEGL005162 Cakile edentula Great Lakes Shore Sparse Vegetation
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: American Searocket Great Lakes Shore Sparse Vegetation
Colloquial Name: Great Lakes Searocket Beach
Hierarchy Level: Association
Type Concept: This community occurs along unstable shorelines in the Great Lakes region of the United States and Canada. Sites are severely affected by wind, waves, and winter ice. Easily shifted sand or gravel substrate permits little vegetation to develop, unless protected by a shoreline configuration that breaks waves and blocks winter ice. Soils are typically sands and gravels with little organic matter. Cakile edentula, Ammophila breviligulata, and Salix myricoides typically grow on sand beaches. Other common plant species include Chamaesyce polygonifolia, Argentina anserina, Salix spp., Schoenoplectus spp., and Xanthium strumarium. A shrub zone (Physocarpus opulifolius, Cornus sericea, Rosa acicularis, etc.) can develop at the inland margin of some gravel beaches. Species found on sand and gravel beaches in most cases are those of other shoreline habitats which gain a tenuous foothold on the beach.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Stands occur on narrow shoreline-sand beaches. Some are associated with large dune systems. The beach can include the sparsely vegetated parts of the upper beach, which is usually beyond the reach of the waves, and can form sand flats. In Wisconsin this type is only on Lake Michigan. The Cakile edentula variety is primarily lacustris. Minnesota may have only a minor occurrence in the Duluth area.

Floristics: Cakile edentula, Ammophila breviligulata, and Salix myricoides (= Salix glaucophylloides) typically grow on sand beaches. Other common plant species include Chamaesyce polygonifolia (= Euphorbia polygonifolia), Argentina anserina (= Potentilla anserina), Salix spp., Schoenoplectus spp. (= Scirpus spp.), and Xanthium strumarium. A shrub zone (Physocarpus opulifolius, Cornus sericea, Rosa acicularis, etc.) can develop at the inland margin of some gravel beaches. Species found on sand and gravel beaches in most cases are those of other shoreline habitats which gain a tenuous foothold on the beach.
Dynamics: Sites are severely affected by wind, waves, and winter ice.
Environmental Description: Sites occur along unstable shorelines of the Great Lakes. Easily shifted sand or gravel substrate permits little vegetation to develop, unless protected by a shoreline configuration that breaks waves and blocks winter ice. Soils are typically sands and gravels with little organic matter. The beach can include the sparsely vegetated parts of the upper beach, which is usually beyond the reach of the waves, and can form a type of sand plain.
Geographic Range: This community occurs along unstable shorelines in the Great Lakes region of the United States and Canada, ranging from sandy shores of all states and Ontario that are associated with the Great Lakes.
