Technical Workshop on Large Wood Applications and Research Needs in River Restoration

Large Wood conference imageThis facilitated workshop focused on identifying large wood research and monitoring needs relevant to river restoration projects. It was a small venue for researchers and practitioners working in the field of large wood and river restoration. Workshop themes included:

The research roadmap (PDF, 459 kB) documents information from group discussions and workshop participants. The objective of the report is to serve as a technical foundation and guide for future research proposals and collaborations on large wood between various government agencies, practitioners, and academia.


An overview of the agenda is provided below, and you can also download the detailed agenda (PDF, 92 kB).

Day 1, February 14, 2012: The first day included introductions, a kick-off talk, and a field trip hosted by King County, Washington and the U.S. Army Corps of Engineers to view and discuss lessons learned on large wood river restoration projects.

Days 2 and 3, February 15 to 16, 2012: The second and third day focused on a mix of presentations and small group break-out discussions to develop lists of research needs, potential methods, and collaborations on the key topics of planning at a reach scale with a geomorphic context, designing at a local scale, and implementation and monitoring guidance. Participants then presented the break-out discussion conclusions back to the larger group so the information can be synthesized and built upon if other ideas are presented. The outcome of the discussions will be documented and serve as the core of the workshop report.
