How Colcom Foundation Funds Restoration Across Southwest Pennsylvania
More than a century of coal mining and heavy industry left southwest Pennsylvania with polluted streams, eroded banks, and thinning forests. Repairing that damage is slow, expensive work, and the Colcom Foundation has made it a central part of its regional giving.
The Pittsburgh-based funder was established in 1996. Its primary mission is to foster a sustainable environment that ensures quality of life for all Americans by addressing the major causes and consequences of overpopulation and its adverse effects on natural resources. Closer to home, Colcom Foundation supports conservation, environmental projects, and cultural assets, with habitat and ecosystem restoration sitting at the center of that commitment.
What the Money Pays For
Colcom Foundation grants have gone toward watershed remediation, streambank stabilization, acid mine drainage treatment, and urban reforestation. The Foundation funds both passive and active treatment systems for mine drainage, matching each project’s method to the specific pollution source at the site. Other supported work includes riparian tree planting, reforestation of abandoned mine land, and heavy metal remediation.
Two grants to Western Pennsylvania Conservancy stand out. A $2 million award in 2006 launched the Conservation Blueprint, a science-based map built on 25 years of Pennsylvania Natural Heritage Program data. A $1 million grant in 2025 began a three-year effort to permanently protect 1,000 acres of headwater land in the Upper Allegheny Watershed. Refer to this page, for related information.
A Long Game With Familiar Partners
Geography shapes the approach. Grants concentrate on the Pittsburgh metropolitan area and nearby river systems, including the Allegheny, Monongahela, and Clarion basins. Keeping the focus regional lets Colcom Foundation sustain partnerships with the same nonprofits for decades instead of spreading money thinly across the country.
Those partners include Allegheny Land Trust, Foundation for Pennsylvania Watersheds, Pennsylvania Environmental Council, WeConservePA, the Natural Areas Association, and Tree Pittsburgh, which has received annual operating support since 2012. Together, they cover land acquisition, policy, conservation law, watershed funding, and urban forestry.
The results show up in measurable ways. Freshwater mussels have returned to rivers once too polluted to hold them. Thousands of acres of forest are now protected. Cumulative giving has also drawn millions more in matched state, federal, and private dollars into regional restoration, extending the reach of each grant well beyond its original amount.
