Decades, or even centuries, of changing and competing land uses have left many of the world's streams degraded, in poor health, and out of balance with the ever-shifting dynamics of their watersheds. This is a basic resource intended to help individuals, groups, organizations, companies, communities, and governments plan and carry out environmentally sound, cost-effective stream corridor assessment, enhancement, and stewardship programs. While not a technical manual for professionals trained in stream restoration, this resource does provide a solid foundation by which volunteers may become informed observers, advocates, and organizers of stream enhancement programs and participants in their implementation.
