Robert T. Zappalorti founded Herpetological Associates, Inc. (HA) in the spring of 1977. The firm specializes in the conservation and ecology of threatened and en­dangered amphibians and reptiles. Robert has conducted extensive scientific research on the bog turtle, wood turtle, red­belly turtle, timber rattlesnake, corn snake, pine snake, blue-spotted salamander, tiger salamander, southern gray treefrog, Pine Barrens treefrog, and many other species. He specializes in conservation and mitigation plans and was the first herpetologist to build artificial hibernacula for snakes and other wildlife in natural habitat areas. Robert has also conducted wildlife inventories, intensive herpetologi­cal studies, and presence or absence surveys for a variety of clients.

He has served as an expert witness and pro­vided testimony in State and County Courthouses and before numerous Township Planning Boards. Robert is a published author of many books, scientific papers, and arti­cles on herpetology. He is also an accomplished wildlife photographer, with photo credits in numerous books and magazines, including National Geographic Magazine. He has served as the official herpetological consultant to the Endangered and Nongame Species Program, Division of Fish and Wildlife, New Jersey Department of Environmental Protection, the Division of Coastal Resources (CAFRA), the New Jersey Pinelands Commission, The Trust for Public Land, and The Nature Conservancy.

Robert also was a Reptile Keeper at the Staten Island Zoological Society between 1964 and 1974, and worked under the late Carl F. Kauffeld.

Michael E. Torroco is a herpetologist specializing in field surveys for Penn­sylvania’s endangered and threatened herpetofauna and works extensively with the federally threatened bog turtle. He is recognized as a qualified bog turtle surveyor in Pennsylvania, New Jersey, Delaware, and Maryland. Also an expert in the ecology of the New Jersey Pine Barrens, Michael has assis­ted in original research on the timber rattlesnake, pine snake, corn snake, and Pine Barrens treefrog.
