The Biomet lab installed a new greenhouse gas flux field site over corn on Bouldin, Island. This is a node in the regional network of greenhouse gas flux stations that are comparing the efficacy of wetland restoration compared to standard agricultural practices in the Delta.
Kyle Hemes passed his Phd Orals Defense. Congratulations
The Biomet lab was part of a team that received the Innovation award from the American Carbon Registry. The award was presented to the developers of two landmark methodologies, one for California wetland restoration and the other for the transition to low global warming potential foams. ACR honored the Sacramento-San Joaquin Delta Conservancy as the lead agency, HydroFocus as the lead author and both U.C. Berkeley and Tierra Resources for technical support for the development of the methodology for the Restoration of California Deltaic and Coastal Wetlands. Funding for the methodology was provided by the California Coastal Conservancy, Department of Water Resources, U.S. Department of Energy, U.S. Department of Agriculture, the Metropolitan Water District and the Sacramento Municipal Utility District (SMUD).

Kyle Hemes, from the Berkeley Biomet lab and DWR counterparts hosted a Delta field visit from a Colorado College climate change economics class. Discussion centered around California’s linked climate and water challenges, how wetland restoration could be used as a climate mitigation activity, and the challenges around measurement and accounting of land use greenhouse gas emissions. The group visited restored wetland sites on Twitchell Island
