The Allegheny County Natural Heritage Inventory identifies and maps Allegheny County's most significant natural areas. The study investigated plant and animal species and communities that are unique or uncommon in Allegheny County; it also explored areas important for general wildlife habitat, education and scientific study. The inventory does not confer protection on any of the areas listed here. It is however a tool for informed and responsible decision-making. Public and private organizations may use the inventory to guide land acquisition and conservation decisions. Local municipalities and the County may use it to help with comprehensive planning, zoning and the review of development proposals. Developers, utility companies and government agencies alike may benefit from access to this environmental information prior to detailed development plans being made. Although the inventory was conducted using a tested and proven methodology, it is best viewed as a preliminary report rather than the final word on the subject of Allegheny County's natural heritage. Further investigations could potentially uncover a few previously unidentified Natural Heritage Areas. Likewise, in-depth investigations of sites listed in this report could reveal greater natural wealth than has been documented here
