As the timber was exhausted and the land burned, many companies simply abandoned their holdings. Conservationists like Joseph Rothrock became concerned that the forests would not regrow if they were not managed properly. They called for the state to purchase land from the lumber companies and for a change in the philosophy of forest management. In 1895 Rothrock was appointed the first commissioner of the Pennsylvania Department of Forests and Waters, the forerunner of today's Department of Conservation and Natural Resources. In 1897 the Pennsylvania General Assembly passed legislation which authorized the purchase of "unseated lands for forest reservations" and the first Pennsylvania state forest lands were acquired the following year.
