We surveyed birds from May to July 1997 and butterflies and skippers (hereafter referred to as butterflies) from May to September 1998 to provide a baseline database of these species in two national parks in Pennsylvania: Allegheny Portage Railroad National Historic Site (ALPO) and Johnstown Flood National Memorial (JOFL). Report was published in 2000.
