The Science Guiding Colcom Foundation’s Habitat Restoration Grants

Nearly three billion birds have vanished from North America since 1970. Researchers documented that decline in a 2019 study by Rosenberg and colleagues published in Science, and it offers a stark measure of how much habitat has been lost across the continent.

For the Colcom Foundation, figures like that help explain why restoration matters. The Pittsburgh-based funder describes its approach as evidence-based conservation grounded in peer-reviewed science, and its habitat grants in southwest Pennsylvania reflect that commitment.

Defining the Work

The Society for Ecological Restoration defines ecological restoration as “the process of assisting the recovery of an ecosystem that has been degraded, damaged, or destroyed.” Southwest Pennsylvania supplies plenty of degraded ground. More than a century of coal mining and industrial development left polluted waterways, unstable streambanks, and cleared land.

Typical repair methods include acid mine drainage treatment, riparian buffer planting, streambank stabilization, and native tree planting. The Foundation funds both passive and active mine drainage treatment, choosing the method that fits each site’s pollution source.

Population, Pressure, and Data

Colcom Foundation’s mission centers on addressing the causes and consequences of overpopulation and its effects on natural resources. It draws on the I = P x A x T framework, introduced by Ehrlich and Holdren in 1971, which links environmental impact to population, affluence, and technology. Growing population and development in the region add pressure on habitat, making restoration more urgent.

Science shows up most clearly in how grants are targeted. A $2 million grant to Western Pennsylvania Conservancy in 2006 created the Conservation Blueprint, which uses 25 years of Pennsylvania Natural Heritage Program data to prioritize high-biodiversity forests, streams, and wetlands across four ecoregions. Since then, the Blueprint has catalyzed more than 10 high-impact projects and helped protect more than 4,000 acres of forestland.

Federal findings inform priorities too. The U.S. Fish and Wildlife Service proposed endangered status for the eastern hellbender in December 2024, citing sediment and water-quality decline. Clarion River acid mine drainage work funded through the Colcom Foundation’s Conservancy partnership has documented hellbenders and freshwater mussels returning to stretches once too polluted for them.

The Foundation also lists transparent communication of its mission, rationale, and grant outcomes among its key principles, giving outside observers a way to track whether the science-led approach is delivering. Refer to this article for more information.
