STATE OF THE ESTUARY: The Wetlands Regional Monitoring Program: A regional vision for coordinated monitoring

An update on the development of a regional plan to monitor the restoration of tidal marshes in the San Francisco Bay Area

The monitoring of tidal wetlands in the Bay Area has typically been implemented on a project-by-project basis in order to fulfill regulatory permit requirements. While providing data and insights for a particular project, it doesn’t provide an understanding of regional tidal wetland status and trends or how drivers such as sea level rise and development are impacting tidal wetlands.  A regional approach to monitoring tidal wetlands is needed to provide insights into where and how to implement tidal marsh restoration projects that would provide the greatest benefit to the diversity and resilience of estuarine habitats.

GUEST COMMENTARY (REBUTTAL): Ecologists see little difference between unimpaired and (truly) functional approaches to flow

This guest commentary was written by Julie Zimmerman, Jeanette Howard, Jon Rosenfield, and Rene Henery in response to The Final Demise of Unimpaired Flows, guest commentary by Robert Shibatani

As river ecologists that work on environmental flows, we’re often confused by the strong reactions we hear at the mention of unimpaired flows. In general, we do not advocate for, nor have we ever experienced discussions contemplating allocation of 100% of unimpaired flow to the environment in rivers that support other critical, beneficial uses. Our work, and the discussions we are party to, are focused on leaving a portion of the unimpaired flow in a river to mimic natural patterns of variability while allowing a portion of the water to be diverted for human use.  In fact, our current water rules in California (and elsewhere) are all hydrologically-sensitive, meaning they change by season and year type to reflect hydrology and allow diverters to still divert in drier years. For example, D-1641 – water quality rules that govern flows into, through, and out of the Delta – is based on unimpaired flow at a coarse scale. What's potentially different about the “unimpaired flow” approaches currently under discussion are that they would apply on a shorter time step (e.g., weekly) and at a finer scale (a continuous percentage, rather than a blocky year type). This would retain more of the natural variability in river flow.
