Callen Run Research Area (IBA 20)

This is a 2500-acre portion of Clear Creek State Forest in Jefferson County.  The area is managed by DCNR in Clarion. It consists of continuous second-growth deciduous forests of three types: oak-dominated, mixed hardwoods, and Eastern Hemlock. Most of the area is drained by Callen Run, a tributary to the Clarion River. The streams are bordered in many places by steep slopes.

A total of 176 bird species have been recorded here, with up to 60 breeding. Characteristic breeding species include Eastern Screech-Owl, Whip-poor-will, Yellow-billed Cuckoo, Black-billed Cuckoo, Ruby-throated Hummingbird, and a variety of warblers.

To reach the Research Area from I-80, follow Route 36 North from Brookville and turn right on Route 949 in Sigel.  Turn right again on Cullen Road at Heath Station.  One can drive within the Research Area by traveling South on Cullen Run Road, crossing over Spring Creek Road onto Fire Tower Road, turning left onto McNeil Station Road, which takes you back to Spring Creek Road, and turning left to return to Callen Run Road.

Important Bird Areas
Pennsylvania’s Important Bird Area (IBA) Program is part of a dynamic worldwide effort to identify and protect outstanding habitats for birds and all wildlife.  Based on strict scientific criteria two areas in Clarion County (Cook Forest State Park and Piney Tract) and also Callen Run Research Area in nearby Jefferson County were selected in 1998. SRAS has formally adopted these IBAs and will monitor and endeavor to protect their habitats.
