California Rice and Wildlife Report Released

From ducks and cranes to giant garter snakes and salmon, flooded rice fields in California’s Central Valley offer important — often vital — habitat to many wildlife species. Yet uncertainties around crop markets, water and climate can prompt some growers to fallow rice fields or change their management practices.

Will today’s rice acreage under current practices be enough to meet key species’ needs? If not, how much rice is needed? Where should it be planted? And what management practices offer the greatest benefit for species of concern?

Scientists from the University of California, Davis, and Point Blue Conservation Science address these questions in a new report, “A Conservation Footprint for California Rice,” written for the California Rice Commission.

“This was a highly interdisciplinary effort that I don’t think has been attempted at this scale for California rice or perhaps any other California agricultural crop working with wildlife,” said report co-lead John Eadie, a UC Davis professor emeritus in the Department of Wildlife, Fish and Conservation Biology who coordinated the 173-page effort among 13 authors. “I think this report provides the baseline for future work to come.”

Core needs

The authors reviewed the core needs of key species living among the region’s rice fields. These include giant garter snakes, wintering ducks, wintering and breeding shorebirds, black terns, sandhill cranes and native fish. They developed a mapping framework of the species’ habitat, as well as an estimate of the rice acreage, management practices and priority locations for rice that would most greatly benefit each wildlife group.
