DR. PETER MOYLE & DR JASON BAUMSTEIGER: Assessing extinction in freshwater fishes

Drs. Moyle and Baumsteiger lay out a proposal for determining when to declare a species extinct The extinction of a species is a major consideration in balancing water supply and environmental needs. It’s usually regarded as a “yes/no” state but its determination can be quite complicated.  In this brown bag seminar, Dr. Peter Moyle and Dr. Jason Baumsteiger discuss general […]

Getting to the Bottom of It: An Overview of the Environmental Monitoring Program’s Benthic Monitoring in the Delta

DWR’s Dr. Betsy Wells takes a look at the creatures that live on the bottom of the Delta Creating a better understanding of bottom-dwelling, or benthic, invertebrate communities enhances our knowledge of the Sacramento-San Joaquin Delta ecosystem. These communities are a crucial link in the Delta’s food web and are a classic bio-indicator of aquatic ecosystem health. In this seminar, […]

Alternative monitoring approaches for large Bay-Delta estuarine wetland restoration projects

Adapting to uncertainty or novelty during accelerated climate change In recent years, many tidal wetland restoration projects have become larger and increasingly becoming more than just a mitigation tool.  Tidal wetland restorations planned or under construction now face major new uncertainties such as accelerated climate change and sea level rise, invasive species, a decline in sediment supply, and other factors […]

Farms as floodplains: A summary after five years of experimental flooding of agricultural land

Studies show the rice-field fish are larger, healthier and more robust than those in the river at the same age One of the recent and notable success stories for California has been the ongoing studies in the Yolo Bypass to use flooded rice fields as habitat for young migrating salmon. The results from the five years of study show the […]

Adaptive Management in Action: The South San Francisco Bay Salt Pond Restoration Project

The largest wetlands restoration project on the West Coast, the project provides a working example for an adaptive management framework applicable to other large habitat restoration projects San Francisco Bay, much like the Delta, has lost an estimated 85 percent of its historic wetlands to development and other human uses.  The dramatic decline in tidal marsh habitats has caused populations […]

Integrated ecosystem modeling for adaptive management: Lessons from 40 years of decision support in the Great Lakes

Limnotech’s Dr. John Wolfe presents two case studies from the Great Lakes which utilized integrated modeling and adaptive management to solve ecosystem issues The Sacramento-San Joaquin Delta is no doubt a complex ecosystem, but it certainly is not the only one; the complexity and uncertainties facing the Bay-Delta system present challenges similar to those in the Great Lakes system.  In […]

Delta Narratives, pt 4: Writers and artists in the Sacramento-San Joaquin Delta

Dr. Gregg Camfield surveys literature written about the Delta, focusing on an American humorist’s vision of Benicia “Stories matter. Contemporary neuroscience fairly certainly supports our basic intuition that individual human beings construct their identities out of stories, and what is true for individuals is also true, though usually in a more complex way, for cultures,” writes Dr. Gregg Camfield in […]
