==History== Cornplanter State Forest was formed as a direct result of the depletion of the forests of Pennsylvania that took place during the mid-to-late 19th century. Conservationists like Dr. [[Joseph Rothrock]] became concerned that the forests would not regrow if they were not managed properly. Lumber and Iron companies had harvested the [[old-growth forest]]s for various reasons. The [[clearcutting|clear cut]] the forests and left behind nothing but dried tree tops and rotting stumps. The sparks of passing [[steam locomotives]] ignited [[wildfire]]s that prevented the formation of [[Secondary forest|second growth forest]]s. The conservationists feared that the forest would never regrow if there was not a change in the philosophy of forest management. They called for the state to purchase land from the lumber and iron companies and the lumber and iron companies were more than willing to sell their land since that had depleted the natural resources of the forests.<ref name="vfsfhistory">{{cite web |url = http://www.dcnr.state.pa.us/forestry/stateforests/valleyforgehistory.aspx |title = History of the William Penn State Forest |access-date = 2007-08-29 |publisher = [[Pennsylvania Department of Conservation and Natural Resources]] |url-status = dead |archive-url = https://web.archive.org/web/20070823033728/http://www.dcnr.state.pa.us/forestry/stateforests/valleyforgehistory.aspx |archive-date = 2007-08-23 }}</ref> The changes began to take place in 1895 when Dr. Rothrock was appointed the first commissioner of the Pennsylvania Department of Forests and Waters, the forerunner of today's [[Pennsylvania Department of Conservation and Natural Resources]]. The [[Pennsylvania General Assembly]] passed a piece of legislation in 1897 that authorized the purchase of "unseated lands for forest reservations". This was the beginning of the State Forest system.<ref name="vfsfhistory"/>
