Weiser State Forest is a Pennsylvania state forest made up of scattered tracts across east-central counties, including Carbon, Columbia, Dauphin, Northumberland, and Schuylkill, with later expansion into Luzerne County. The Appalachian Trail crosses its lands. It emerged from Pennsylvania’s broader state forest system, created after nineteenth-century logging, iron production, and wildfire severely damaged the state’s woodlands. Conservationists such as Dr. Joseph Rothrock pressed for active forest management, and laws passed in the 1890s enabled the state to acquire damaged lands for forest reservations. Named for Conrad Weiser, the forest’s present form reflects later district realignments, land acquisitions, and long-term ecological recovery.
