Classification
Scientific Name: Laurentian-Acadian Lakeshore Beach
Unique Identifier: CES201.586

Summary: This system encompasses primarily upland vegetation along lakeshores or rivershores in northern New England, southeastern Canada, and the upper Midwest (not including the Great Lakes). Some areas may be briefly inundated during high water periods. The substrate is sandy to gravelly, sometimes consolidated rock; there may be muddy patches. Ice-scour is not a major influence, although it may be locally important. These shores may be narrow zones of shrubs and/or sparse vegetation on rocks or sandy beaches. Descriptions of these beaches from Maine, New Hampshire, Vermont, and Minnesota suggests a variable structure and composition influenced by exposure, substrate, and how wet the substrate remains. The upper zone often features shrubs; these may include Myrica gale, Gaylussacia baccata, Salix spp., and Aronia melanocarpa. Creeping shrubs such as Hudsonia spp., Juniperus horizontalis, and Prunus susquehanae may be locally important. The herbaceous flora likewise varies; Schizachyrium scoparium, Dichanthelium clandestinum, Cyperus spp., Dulichium arundinaceum, and Spartina pectinata are representative graminoids; forbs may include Argentina anserina, Lechea intermedia, Scutellaria lateriflora, and Mimulus ringens, among others.

Classification Approach: International Terrestrial Ecological Systems Classification (ITESC)

Classification Comments: Very little data on these. May not be defensible as a separate system, keep in for now as a placeholder. If it is combined with the surrounding uplands, the associations tagged to this system may become orphans.
