In the Pacific Northwest, an estimated 328,000 km of U.S. national forest roads alone will damage waterways for decades if untreated. Streams that once supported abundant fish in former lush forests can no longer withstand hot dry summers, intense rain, and flash floods. Currently 10 fish species are listed as threatened and eight are endangered in this region. In fact, watersheds everywhere need repair. Restoration must be comprehensive.
Watershed restoration demands an understanding of hillslope, fluvial and riparian processes.
TerraWave is on the leading edge of research and application of biotechnical and geomorphic techniques that restore naturally, rapidly and for the long-term. We teach these techniques and the specialized use of heavy equipment, as well as manage projects, both large and small scale.
