Pennsylvania’s state forest system includes dozens of special wild and natural areas set aside to protect unique or unusual biologic, geologic, scenic and historical features or to showcase outstanding examples of the state’s major forest communities. Natural areas are “managed” by nature and direct human intervention is limited. They provide places for scenic observation, protect special plant and animal communities and conserve outstanding examples of natural beauty. Wild areas are generally extensive tracts managed to protect the forest’s wild character and to provide backcountry recreational opportunities.
