The Pennsylvania Biological Survey (PABS) is a nonprofit, all-volunteer organization whose purpose is to increase knowledge of, and foster the perpetuation of, the natural biological diversity of the Commonwealth of Pennsylvania. Among other tasks, the Survey is responsible for determining the status (endangered, threatened, etc.) of wild species of animals, plants and other organisms in the state (click HERE to see how that’s done). Its over 150 members (including more than 70 PhDs) are scientists from throughout Pennsylvania, representatives of state and federal agencies concerned with natural resource management, representatives of Pennsylvania’s major natural history museums and scientific institutions, and other interested and knowledgeable individuals. PABS is governed by a Steering Committee that functions through technical and standing committees focusing on species groups or program areas. To learn more, click on the links at left.
