Long Point Area, Lake Erie; Saginaw Bay Area, Michigan: Impacts of Water Level Fluctuations on Wetland Birds

Gerald Niemi;Robert Howe
Development of regulation plan performance indicators describing water-level regime impacts on change in habitat area for thirteen wetland-associated bird species, including four listed species-at-risk: least bittern, black tern, king rail, and yellow rail within the Long Point Bay wetland complex. The performance indicator metric is based on a direct relationship between the amount of available wetland habitat and viable population levels of a species, and represents an assessment of the amount of available breeding habitat for a combination of the thirteen wetland species listed evaluated on different water level regime scenarios for Long Point (Lake Erie) and Saginaw Bay (Michigan). There is considerable information on the breeding density of the nine unlisted species within Great Lakes wetland complexes, and the performance indicators are representative of ecological conditions and responses for different water level scenarios.
