This IBA includes the Germantown MetroPark managed by Five Rivers
MetroParks. The high quality stream, Twin Creek, runs through the wooded corridor. Steep topography and varied moisture gradients provide a variety
of microhabitats within several forest types. The park contains steep ravines exhibiting old growth timber, cedar glades, cool-season and planted warm-
season grasses, hillside xeric prairies, several ponds, and created wetland. It is the largest tract of old growth forest in Montgomery County, with mixed mesophytic woodland of mature beech and maple on the uplands, and bottomland hardwoods in the riparian areas. The size, quality, and age of the woodlands are exceptional. Large tracts of managed grasslands are found within the park.

Ornithological Summary

The diversity of the mature upland woodlands with the intact riparian corridor attracts an exceptional concentration of neotropical migrants. Open fields attract grassland species. Raptors are common. Past breeding species include American Woodcock, Barred Owl, Chuck-will's-widow, Pileated Woodpecker, Brown Creeper, Brown Thrasher, Black-throated Green Warbler, Worm-eating Warbler, Northern Parula, Yellow-throated Warbler, Prairie Warbler, Pine Warbler, Cerulean Warbler, Worm-eating Warbler, Louisiana Waterthrush, Kentucky Warbler, Hooded Warbler, Summer Tanager, Henslow's Sparrow, and Bobolink, with 13 species on the high-priority list (75 breeding species recorded in 2003, including 12 species of warblers). Coniferous plantings attract Red-breasted Nuthatches, Purple Finches, Pine Siskins, and an occasional Crossbill. Wild Turkeys inhabit the IBA.

Conservation Issues

The site is managed for diversity and forest conservation. It has exceptional spring wildflowers. Twin Creek has the highest diversity of macroinvertebrates in Ohio and second highest fish diversity. Threats include development of adjacent parcels and non-native invasive plants.
