Bob Zappalorti started at the Staten Island Zoo in 1963 working under world renowned herpetologist Carl Kauffeld. Under Kauffeld’s guidance and mentorship, Bob began studying the rapidly declining Bog Turtle (Glyptemys muhlenbergii) throughout New Jersey, Pennsylvania, and North Carolina. In 1977 Bob founded Herpetological Associates to assist clients comply and adhere to the newly signed Endangered Species Act of 1973 and the formation of the New Jersey Endangered and Nongame Species Program of 1973, while still ensuring the preservation of threatened and endangered species. HA conducted early Bog Turtle, Northern Pine Snake, Red Corn Snake, and Timber Rattlesnake studies for the Endangered & Nongame Species Program, NJDEP. In 1992, HA was awarded a research contract with Pennsylvania Chapter of The Nature Conservancy to conduct an intensive Bog Turtle survey throughout eastern and central Pennsylvania which included nesting ecology, egg predator studies, and searches for new populations.

Until recently, herpetology has been a neglected area of science. There is now a great demand for knowledge about the needs of reptiles and amphibians, and other wildlife. HA is dedicated to the conservation and long-term survival of the interesting organisms we study. We strive to create a balance between economic progress and smart conservation. We are one of the few consulting companies to publish books and peer-reviewed scientific papers. Our services have expanded to include a variety of amphibian, reptile, rare plant, and bird species. State and federal agencies, non-profit groups, engineering firms, developers, and private citizens have come to rely on HA as a dependable source for all their environmental consulting needs.
