Ecological systems and subsytems (about):
TERRESTRIAL - OPEN UPLANDS:
Great Lakes dunes (guide)
A community dominated by grasses and shrubs that occurs on active and stabilized sand dunes along the shores of the Great Lakes. Unstable dunes are sparsely vegetated, whereas the vegetation of stable dunes is more dense, and can eventually become forested.
LACUSTRINE - NATURAL LAKES AND PONDS:
Great Lakes exposed shoal
The aquatic community of the shallow littoral zone of the Great Lakes that occurs along windswept shores that are exposed to wave action, typically associated with islands and points. The lake substrate may be sandy, gravelly, cobbly, bouldery, or with submerged bedrock outcrops.
TERRESTRIAL - OPEN UPLANDS:
Sand beach
A sparsely vegetated community that occurs on unstable sandy shores of large freshwater lakes, where the shore is formed and continually modified by wave action and wind erosion. Characteristic species that are usually present at very low percent cover include various grasses and other herbs.
