A Collaboration with Rural Alaskans: The driftwood harvest in a changing climate

Speaker: Dr. Chas Jones, EPA Post-doctoral Fellow
This study examined flood events in the Yukon River with the goal of understanding how actual or perceived changes in driftwood availability are related to river hydrology and how future changes in hydrology may affect the driftwood harvest. The presenters combined information gathered from informant interviews, USGS gauging stations, U.S. Census data, and numerical models of past driftwood harvest rates to estimate changes in future driftwood harvest rates. They determined that neither average date of spring break-up nor the June Rise floods had changed significantly between 1977 and 2012, but the date of the June Rise had become much more variable since 1993.
