The Keystone 10 Million Trees Partnership, comonly referred to as K10, is a collaborative effort of national, regional, state, and local agencies, conservation organizations, outdoors enthusiasts, businesses, and citizens committed to improving Pennsylvania’s communities, economy, and ecology by planting 10 million trees in priority areas across the Commonwealth by the end of 2025.

The Chesapeake Bay Foundation coordinates the partnership in support of Pennsylvania’s efforts to reduce pollution in local rivers and streams and meet its commitment to the regional Chesapeake Clean Water Blueprint.

Our Partners
a team effort

Without our partners, the initiative to plant 10 million trees across Pennsylvania would be an impossible task. Our partners provide resources, technical support, research, outreach, volunteers, and the resolve to ensure our goals are met. They range in size, location, and expertise, yet all with a common goal of restoring Pennsylvania’s landscapes.

what drives us

The Partnership has three goals:

Reduce pollution: Stop millions of pounds of nitrogen and sediment from flowing down the Susquehanna and Potomac Rivers and into the Chesapeake Bay.

Pick-up the pace: Put Pennsylvania’s Blueprint commitment for riparian buffers and urban tree canopy back on track through the planting of 10 million trees by 2025.

Raise new voices: Inspire and equip a strategically diverse coalition to demand public action for clean water and a better Pennsylvania.

where we‘re planting

The Partnership has multiple targets for plantings: farms, streets and abandoned and legacy mine land.

– Along streams: Streamside buffers – forested areas next to streams, lakes, and wetlands on farms and other areas – help filter polluted runoff, provide habitat, and stabilize stream banks.

– In cities and towns: Urban and suburban tree plantings occur on developed land where trees help filter polluted runoff, provide shade, and increase property values.

– On abandoned mine lands: Landscapes adversely impacted by pre-1980 coal-mining operations need intervention to loosen compacted soil, correct chemical or nutrient deficiencies, and replace current vegetation.

Who is the Chesapeake Bay Foundation

Founded in 1967, the Chesapeake Bay Foundation (CBF) is the largest independent conservation organization dedicated solely to saving the Bay.

Serving as a watchdog, CBF fights for effective, science-based solutions to the pollution degrading the Chesapeake Bay and its rivers and streams. Their motto, “Save the Bay,” is a regional rallying cry for pollution reduction throughout the Chesapeake’s six-state, 64,000-square-mile watershed, which is home to more than 18 million people and 3,000 species of plants and animals.

With offices in Maryland, Virginia, Pennsylvania, and the District of Columbia and 15 field centers, CBF leads the way in restoring the Bay and its rivers and streams. For more than 50 years, they have created broad understanding of the Bay’s poor health, engaged public leaders in making commitments to restore the Chesapeake, and fought successfully to create a new approach to cleanup that features real accountability—the Chesapeake Clean Water Blueprint.

The Chesapeake Bay Foundation coordinates the Keystone 10 million trees partnership in support of Pennsylvania’s efforts to reduce pollution in local rivers and streams and meet its commitment to the regional Chesapeake Clean Water Blueprint.
