HUNTINGDON COUNTY NATURAL HERITAGE INVENTORY Prepared for: The Huntingdon County Planning Commission 205 Penn Street, Suite 3 Huntingdon, PA 16652 Prepared by: Western Pennsylvania Conservancy 209 Fourth Avenue Pittsburgh, Pennsylvania 15222 This project was funded through grants supplied by the Department of Community and Economic Development, the Department of Conservation and Natural Resources – Office of Wild Resource Conservation. PREFACE The Huntingdon County Natural Heritage Inventory identifies and maps Huntingdon County’s most significant natural places. The study investigated plant and animal species and natural communities that are unique or uncommon in the county; it also explored areas important for general wildlife habitat and scientific study. The inventory does not confer protection to any of the areas listed in the report. 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 the creation of detailed development plans. 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 Huntingdon County’s natural heritage. Further investigations could potentially uncover previously unidentified Natural Heritage Areas. Likewise, in-depth investigations of sites listed in this report could reveal features of further or greater significance than have been documented. Some of the areas described here are privately owned. In such cases, anyone wishing to visit these areas should obtain permission from the property owner(s) prior to visitation. The Western Pennsylvania Conservancy served as the principal investigator for the study and prepared the report and maps that are the products of the study. Established in 1932, Western Pennsylvania Conservancy is a private non-profit natural resource conservation organization headquartered in Pittsburgh. WPC’s mission is to save the places we care about by connecting people to the natural world. As part of its mission, WPC works to sustain the natural heritage of Commonwealth: its native plant, animal, and habitat resources. To reach its goals, WPC initiates conservation projects independently and establishes partnerships with agencies and organizations having similar interests. County Natural Heritage Inventories are conducted by WPC through such partnerships. Any questions concerning sites or updates to the inventory may be addressed to the Western Pennsylvania Conservancy, 209 Fourth Avenue, Pittsburgh, PA 15222; phone: (412) 288-2777. The Huntingdon County Planning Commission administered this study. Requests for copies of the inventory can be addressed to the Huntingdon County Planning Commission, 205 Penn Street, Suite 3, Huntingdon, PA 16652, phone: (814) 643-5091, email: [email protected]. i ACKNOWLEDGEMENTS We would like to acknowledge the many citizens and landowners of the county and surrounding areas who volunteered information, time, and effort to the inventory and granted permission to access land.
