Upcoming Field Course- Science and Restoration on Unstable Terrain

Join us for a 5-day field course exploring the scientific and practical challenges of stream restoration in the unstable terrain of the Mattole River and its watershed. Daily lectures, discussion, and field tours to field sites (including restoration projects) cover a range of topics including geomorphologic processes, salmonid habitat restoration, in-stream flow enhancement, and Mediterranean river ecology.

The Mattole River flows through an exceptionally dynamic landscape on Humboldt County’s Lost Coast.  Salmon historically thrived here despite periodic disturbances from earthquakes and intense storms, but massive clear-cutting in the mid-20th century set the stage for widespread loss of habitat resulting from accelerated erosion, excessive suspended fine sediment loads, channel siltation and aggradation.  The river and its basin have been naturally recovering since, encouraged by habitat restoration projects.  The Mattole is an excellent setting in which to observe interactions among physical, ecological and social systems, with a strong data set from extensive citizen monitoring.

The course is taught by experts with experience ranging from the local to regional to global: Matt Kondolf (UC Berkeley), Danny Hagans (Pacific Watershed Associates), Alison Purcell O’Dowd (Humboldt State U), Tommy Williams (NOAA Fisheries), Tasha McKee (Sanctuary Forest), Sam Flanagan (BLM), Drew Barber (Mattole Salmon Group, MSG), John Williams (Mattole Restoration Council, MRC), and Nathan Queener (MSG and MRC).
