This IBA is made up of 9 discrete locations and a .25 mile radius around each one. Each location is a cliff used as a nesting sites by Peregrine Falcons. The IBA does not include the area between the sites. While the sites are geographically separate, and involve different landowners/managers their combined importance to this species, along with their common conservation and monitoring needs argues for regarding them as one, unique IBA. These site locations are current as of summer 2003 when 10 sites were known to exist. Due to landowner concerns only 9 sites are included in this IBA.
