​Tiadaghton State Forest

Tiadaghton State Forest is named for a native-American term originally describing Pine Creek. Though most of Tiadaghton State Forest’s 146,539 acres reside in Lycoming County, some tracts extend into:

• Tioga County
• Potter County
• Clinton County
• Union County

Tiadaghton’s forest features high-country flats bisected by clean, fast-moving mountain streams, including the legendary Pine Creek and Slate Run.

It is one of eight state forests located in the Pennsylvania Wilds region.

Come and explore the many interactive exhibits at the Tiadaghton Resource Management Center (PDF) that tell the story of the area and the work of DCNR’s Bureau of Forestry.

Tiadaghton State Forest Management

DCNR’s Bureau of Forestry manages our state forests for their long-term health and productivity while conserving native wild plants. These forests are managed as “working forests” and provide a suite of uses and values to Pennsylvania citizens, while maintaining the forest’s wild character.

Our state forests are managed for:

• Pure water
• Recreation
• Scenic beauty
• Plant and animal habitat
• Sustainable timber and natural gas
• Many other uses and values

The management of our state forests is guided by the State Forest Resource Management Plan.

Tiadaghton State Forest Resource Management Plan

DCNR’s Bureau of Forestry is in the process of revising the Tiadaghton State Forest Resource Management Plan (SFRMP). A district-level state forest management plan is written for each of the bureau’s 20 forest districts across the state.

Citizens may review the newest draft of the Tiadaghton State Forest Resource Management Plan (PDF).

Harvest Schedule

Local state forest harvest schedules promote and maintain desired forest landscape conditions while providing a sustainable flow of forest products.

Ecosystem Management

The Bureau of Forestry has adopted “ecosystem management” as its principal strategy for managing state forests. This approach seeks to conserve the natural patterns and processes of the forest while advancing long-term sustainability.

Ecosystem management promotes the conservation of plant and animal communities and the landscapes and habitats that support them. It also accounts for needs and values of people and communities.

This results in a holistic, integrated approach to managing forest resources.

A Working Forest

As you travel throughout the state forest, you’ll see examples of our forests “at work.” Some of these management practices are more noticeable than others, such as:

• Active timber harvests
• Deer exclosure fences
• Natural gas drilling sites
• Prescribed fires
• Gypsy moth spraying

Others are more subtle, such as the:

• Protection of a vernal pool
• Buffering of a stream from timber harvesting
• Setting aside of a special area to conserve its wild character or protect a rare plant community

Each of these management practices and activities play a vital role in the management and conservation of our state forest system.

Dual Certified Forest

Pennsylvania’s 2.2-million-acre state forest system is one of the largest dual certified forests in North America. The forest is certified under Forest Stewardship Council™ and Sustainable Forestry Initiative© standards.

The FSC© is an independent organization supporting environmentally appropriate, socially beneficial, and economically viable management of the world’s forests.

SFI© certification focuses on protection of water quality, biodiversity, wildlife habitat, species at risk, and forests with exceptional conservation value.

Dual certification ensures that Pennsylvania’s state forests are managed to the highest third-party standards.
