The Role of Trees and Forests in Healthy Watersheds
... Cutting timber affects both water quantity and quality. Clearcutting (harvesting all trees) allows more water to flow to streams, because there are no leaves to intercept rain and snow (some of which would later evaporate) and roots no longer take water from the soil. Areas being considered for clea ...
