Streams that run through farmland face a particular set of problems. Livestock trample banks, soil washes in after heavy rain, and old structures can block fish from moving through the channel. Little Mahoning Creek in western Pennsylvania dealt with versions of all of these.
A restoration project funded through the Colcom Foundation’s Conservation Blueprint grant set out to fix them. Western Pennsylvania Conservancy led the work, partnering with local agricultural landowners rather than working around them.
What Crews Built
The project combined several standard restoration tools. Streambank stabilization structures held eroding banks in place. Riparian buffers, strips of vegetation along the water, shaded the stream and trapped runoff before it reached the channel. Livestock fencing kept cattle out of the creek. Crews also removed barriers to fish passage.
Together, these steps reduced sediment and pollutant loads entering the creek and protected miles of stream. The project also supports continuing research into hellbender and brook trout populations in the watershed.
How the Project Got Funded
The money traces to a 2006 decision. That year, Colcom Foundation awarded Western Pennsylvania Conservancy $2 million to create the Conservation Blueprint, a map of priority forests, streams, and wetlands built on 25 years of Pennsylvania Natural Heritage Program data. The Blueprint covers four western Pennsylvania ecoregions and has since catalyzed more than 10 high-impact projects, leveraged over $4.2 million in additional funding, and protected more than 4,000 acres of forestland.
Little Mahoning Creek is one of those projects. Its focus on hellbenders gained added weight in December 2024, when the U.S. Fish and Wildlife Service proposed endangered status for the eastern hellbender, citing sediment and declining water quality. Because the salamander breathes through its skin, muddy water is a direct threat to its survival.
Working with farmers matters in a region where many streams pass through private agricultural land. Projects that offer landowners practical improvements, such as fencing and stable banks, can protect water quality while keeping farms working.
The Colcom Foundation has made this kind of collaborative, data-driven work a hallmark of its regional grantmaking, pairing scientific priorities with partners who know the land. See related link for more information.
