20 Great Lakes Barrens R Habitat The shores of the Great Lakes contain many unique habitats. This community type is one of them. Occurring in wide, sandy depressions between dunes, these barrens appear almost desert-like. They can be associated with interdunal wetlands, however, and may, in fact, sometimes be former wetlands that have filled with windblown sand. The neutral sandy soils in these former embayments are typically xeric, but during periods of high lake levels, water tables may be at or close to the surface. The major disturbances are shifting dunes and human encroachments. Signature trees Several conifers and hardwoods occupy these barrens: • White pine • Red pine • Jack pine • Northern white cedar • Paper birch • Balsam poplar 128
Great Lake Barrens Trees in barrens, like these red pines, often grow in clumps. Associated plants One or more of these low shrubs may be prominent: • Common juniper • Creeping juniper • Buffalo berry • Velvetleaf blueberry The ground layer is typically sparse and may consist of: • Bearberry • Beach heath • Poison ivy • Cudweed • Butterfly weed • False Solomon seal • Hairy puccoon • Beach grass • Dune grass • Fescue • Poverty grass • June grass • Nut grass Distribution and status These communities are very locally distributed along the shorelines of lakes Huron, Michigan, and Superior. Outside the protection of parks and reserves, their status is tenuous. Unregulated shoreline development and rampaging dune vehicles are constant threats. 129
