What is an IBA?
An Important Bird Area, determined by the National Audubon Society, is a “site where significant numbers of birds concentrate for breeding, migration, or wintering.” The Chagrin River Corridor IBA is a relatively intact contiguous riparian corridor surrounded by developed residential area, and includes Holden Arboretum, Penitentiary Glen, North and South Chagrin Reservations, Chapin Forest, and the Audubon Sanctuaries in Aurora and Willoughby Hills. The ASGC has begun an initiative to concentrate conservation and monitoring efforts within this IBA. more
