Key Activities:

  • Planting 5,000 trees across 25 acres
  • Improving watershed health and stabilizing streambanks

Project Description:
Working with the Western Pennsylvania Conservancy, Alcoa Foundation and American Forests are improving watershed health in Allegheny County, Pa., by planting 5,000 native trees across 25 rural acres.

Why This Project:
Waterways in Allegheny County have been suffering in recent years from excess sediment caused by streambank erosion. Many waterways in the county are devoid of trees and other woody vegetation, whose roots keep soil from eroding. This project is focusing on improving the health of high-priority areas by planting native Pennsylvania trees along waterways to help stabilize the eroding banks. Beyond providing stability to the banks, the tress will also act as pollutant filters and will provide shade to lower water temperatures, improving aquatic habitat.

Why Allegheny County:
Three major rivers converge in Allegheny County, Pa.: the Allegheny, Monongahela and Ohio. In actuality, the Allegheny and Monongahela Rivers meet in Pittsburgh, forming the Ohio River. As the largest tributary of the Mississippi River, the Ohio River drainage basin covers more than 189,000 square miles, impacting 15 states. Unfortunately, the Ohio River is also one of the most polluted in the country. By restoring streambank health in Allegheny County, this project is helping restore health to a vitally important U.S. waterway.
