AB: The first comprehensive database on river restoration across the United States provides a new context for evaluating restoration status and trends nationally. Our synthesis of >38,000 project records indicates that river restoration projects and expenditures have increased exponentially over the past decade with more than a billion dollars spent annually since 1990. Most projects are intended to enhance water quality, manage riparian zones, and improve instream habitat. The extent of restoration activity varies by region, with the greatest number of projects occurring in the Pacific Northwest. Only 14% of project records document any form of project monitoring, and little if any of this information is either appropriate or available for assessing the ecological effectiveness of restoration activities.
