Our Team: John Chenger, President of BCM
John is President of Bat Conservation and Management, Inc. (BCM), a company he formed in 1998 to provide specialized bat-related consulting services nationwide, remarkably successful artificial bat roosts, and field gear for bat research. John’s experience includes thousands of hours underground, mapping, photographing, and winter inventorying caves and mines. Above ground experience includes summer and fall bat capture surveys, abandoned mine and cave assessments, and rocky habitat assessments. John is an expert in bat echolocation call analysis throughout North America. His first experience with radio tracking spring migrating Indiana bats was in 2000, and in 2019 he led a massive fall project coordinating up to 15 ground and air trackers. Since 2004 he has been a recurring instructor at nationwide training workshops offered by Bat Conservation International and Bat Survey Solutions, a curriculum designed to train serious students, consultants, agency biologists, and land managers in current research and management techniques for the study and conservation of bats. Other work included the Pennsylvania Game Commission, professional photographer & videographer, and Director of Interpretation at a commercial cave.
