Proposals

 The California Department of Fish and Wildlife (CDFW) today announced the selection of seven projects to restore wetlands that will reduce the emission of greenhouse gases (GHGs) and provide other ecological co-benefits.

The Hill Slough Restoration Project (,577,413 to Ducks Unlimited, Inc.) will restore 603 acres of managed seasonal wetland to tidal wetland and restore 46 acres of existing upland to tidal wetland in the Suisun Marsh. The project will have an estimated GHG benefit of 25,242 MTCO2e. The Biomet lab will monitor greenhouse gas fluxes in this wetland
