The Delta Landscapes project: Creating a spatial framework to inform restoration planning

Pages from 2014-10-29-311PM1-GROSSINGER_DNPost_Page_21

A new report uses landscape metrics in both the historical and contemporary Delta to help define, design, and evaluate functional, resilient landscapes for the estuary’s future The state of California has set ambitious restoration goals for restoration of the Delta’s ecosystem as embodied in the Delta Plan; those goals include restoring large areas of interconnected habitats within the Delta and […]

Yolo Bypass Symposium part 2: Fish, fowl, and the mercury conundrum

Wetland birds sliderbox

Restoration efforts have succeeded in restoring waterfowl populations in the Yolo Bypass; can the same happen now for fish?  Plus the latest research on methylmercury and wetlands restoration. When the floodwaters flow into the Yolo Bypass in the late winter and early spring in some years, dramatic changes occur. Salmon, splittail, and other native fish species come onto the floodplain […]

When it comes to fish habitat, offers they can refuse

Suisun-Marsh Matthew Young slider

From Estuary News: “The numbers are daunting: 8,000 acres to be restored to fish-friendly tidal habitat in order to comply with federal wildlife agencies’ Biological Opinions; another 65,000 if and when the Bay-Delta Conservation Plan is implemented; more still in mitigation for levee operations. Where will it all come from? Some parcels suitable for restoration are already publicly-owned, but not […]

Matt Nobriga: The utilization of tidal marshes by fishes of the Upper San Francisco Estuary


At the 2014 Bay Delta Science Conference,  Matt Nobriga, a fish biologist with the U.S. Fish and Wildlife Service, gave this presentation on how fish utilize tidal marshes in the Delta.  He began by noting that the despite a lot of research over the past decades, there is still much uncertainty regarding tidal marsh restoration. The first issue of the […]

Dr. Peter Moyle: Novel Ecosystems of the Suisun Marsh and the Delta – A New Reality


The Delta of our modern times bears little resemblance to its historical self, a mix of native and non-native species existing in an environment that has been long been sculpted to suit society’s purposes.  Dr. Peter Moyle, Associate Director for UC Davis Center for Watershed Sciences and professor with the Wildlife, Fish, and Conservation Biology Department, describes the resulting Delta […]

Chris Enright: Direct and Indirect Effects of Large-Scale Restoration and Implications for Science and Management


Chris Enright began by saying that the title was quite a large topic, so he would be concentrating on physical processes to make larger points centered around tidal energy. “Tidal energy really is the primary driver down in the estuary,” he said. “Tidal energy starts a cascade of physical processes that affects and controls tidal range, tidal currents, sheer stresses […]

Bruce Herbold: The Value of Wetlands to Fish


Bruce Herbold began by telling a personal story. “I have some friends in Austria, and the dearest of them, her father, when he retired, took the family’s fortune and retired out into the countryside where he built a very large house,” he said. “And after he’d been living out there for awhile, he died. So her inheritance was a completely […]

A restoration hub for the Delta: Better tools and processes for science-based restoration

Delta Restoration Hub open slide

Restoration in the Delta has always been challenging, at best. Habitat restoration objectives already number in the tens of thousands of acres, and far more if the Bay Delta Conservation Plan should come to pass. But restoration on a large scale presents many challenges.  The proposed Delta Restoration Hub is an integrative model for planning, implementation, and analysis. intended to address the […]

Dr. Stephen Brandt: Habitat quality: A fish’s perspective


The 8th Biennial Bay Delta Science Conference brought together over a thousand scientists, managers, and policy makers to Sacramento to hear the latest advances in scientific information and ideas on water resource management in the Delta, its watershed, and the San Francisco Estuary. As the fifth and final plenary speaker, Delta Independent Science Board member Stephen Brandt began by saying […]

A Delta Transformed: New San Francisco Estuary Institute Report Reveals Dramatic Changes to Delta Ecosystem

A Delta Transformed

From the Department of Fish and Wildlife: A recent study produced by the San Francisco Estuary Institute-Aquatic Science Center and funded by the California Department of Fish and Wildlife (CDFW) identifies the dramatic ecological transformation of the Delta over the past 150 years. Developed by a group of scientists and resource managers, “A Delta Transformed” explains the relationship between specific […]
