Trees to Tap: How Forest Practices Affect Oregon's Municipal Water

By Jon Souder

Forests produce economic benefits such as timber, forest products and jobs. They also provide wildlife habitat, recreation, carbon storage and clean water. In fact, most of Oregon’s drinking water is sourced from our forests. But logging, forest road building, using herbicides and other activities related to growing and harvesting timber can impact the quality and quantity of water. Oregon State University scientists examine these links in this comprehensive look at watershed health.
