Delta Primary Production Workshop

Sixteen local and national experts met for a three-day workshop hosted at SFEI to develop a plan that will for the first time quantify primary production in the Sacramento-San Joaquin Delta, both historically and today. During the workshop (October 28-30), scientists with expertise in primary producer groups, hydrodynamics, and food web dynamics integrated existing data, scientific literature, and best professional judgment to build a new synthesis of past and contemporary production and its ability to support to support the base of the Delta food web. Building upon SFEI's work in the Delta Landscapes project, and funded by the Delta Science Program and USGS, this is the first stage of a planned three-phase project. The workshop synthesis will be communicated in a report describing the approach for quantifying order-of-magnitude estimates of primary production. This report will serve as a foundation for a published paper that will carry out the estimates of past and present production, and highlight important drivers of production in the Delta. The paper will then set the stage for building a larger research project that will guide future science, management, and restoration of Delta food webs.
