Since 1956, The Nature Conservancy has worked in Pennsylvania to protect nearly 100,000 acres of land. During this time, TNC has also become a conservation leader in restoring Pennsylvania’s streams and rivers, collaborating with farmers on improving soil health and increasing stormwater management in urban areas, all while addressing the impacts of climate change in these places.
Conserving nature in Pennsylvania over more than four decades has provided an opportunity to pursue larger, more complex projects than ever before. Time is of the essence, and we are up for the challenge. However, it is important to recognize the true urgency of our work in a world that is projected to have more than nine billion people by 2050.

Protecting nature—and providing water, food and energy to a growing population—are no longer mutually exclusive goals. Addressing these together are paramount to sustaining life on Earth. Can we design a future that meets people’s basic needs without further degrading the planet? Yes!
This work must occur at an unprecedented scale with little time to waste. It begins organizing our work around four priorities:
- Protecting Land and Water
- Tackling Climate Change
- Providing Food and Water Sustainably
- Building Healthy Cities
See how we are doing in our annual Accomplishments Report.
Pennsylvania Milestones
A group of volunteers protected 500 acres in Susquehanna County to create the Woodbourne Forest & Wildlife Preserve. TNC has continued to work here through the years, growing the preserve to 648 acres and into a focal site for environmental education and efforts to combat the invasive hemlock woolly adelgid.

The Nature Conservancy officially opened its doors in Pennsylvania.

Played a key role in creating the Keystone Fund, a permanent funding source dedicated to investing in recreation, parks, conservation, historic preservation and more in communities across the state.

Initiated the Monroe County Citizens for Open Space, a successful campaign that garnered $25 million for land protection and leveraged an additional $50 million in matching funds to protect more than 12,000 acres. The Conservancy used this experience to help others in Pike, Northampton and Lehigh counties, and in Stroud Township, to leverage more than $100 million in public funding for open space preservation in those areas.

Celebrated the establishment of the Cherry Valley National Wildlife Refuge, a 24,000-acre refuge in Monroe and Northampton counties. The event marked more than a decade since TNC began protecting land and working with community and business groups to generate demand for the refuge.

Played a major role in writing controlled burn legislation that created state standards for wildlife habitat restoration, scale, training and qualifications for prescribed fire practitioners.
