25 Pa. Code § 9.314
A comprehensive Statewide natural areas program to identify, protect and preserve elements of natural diversity must include a consideration for those areas containing rare, threatened or endangered plant or animal species. In recent years there has been a growing concern to identify these species, regulate their use, and maintain habitat conditions necessary for their survival. Most of the effort has been focused on those species of national significance listed in the Federal Register. The realization of a sound, comprehensive, Statewide natural areas system will require increased involvement and concern by the Commonwealth to strengthen State activities concerning rare, threatened, and endangered species of Statewide importance. Therefore, it shall be the Environmental Policy of the Commonwealth to continue to identify and protect the rare, threatened, and endangered species of this Commonwealth and to intensify efforts to protect and maintain the habitats of these species.
