What We Do

CEMAR undertakes research, planning, and stakeholder facilitation projects with the intent of balancing conservation and restoration with other beneficial uses such as water supply and flood protection. We work across the public sector with individual jurisdictions, interest-based coalitions, and State and Federal agencies to establish scientifically-sound management directions.

Our Programs

Migrating trout being released in Alameda Creek Restoration of steelhead trout will not only preserve this species for future generations, it will also focus people and policy toward rehabilitating California's coastal streams.

A viable steelhead population is an indicator of the ecological health of a watershed, providing an easily understood metric for assessing the impact of human activities.


You can't live in California without being aware of conflicts around water. Many people assume that if we're going to restore streams and their aquatic life, humans are going to have to do with less water for our farms and our homes.

Ritchey Creek CEMAR's conservation hydrology program is demonstrating that there is enough water for people and the environment.

By using scientific methods to understand the natural flow regime of California's streams, and how the flora and fauna of our region have evolved with natural variations, we are discovering that humans can obtain water for our homes and farms while minimizing ecological impacts.


There is a broad public consensus that protecting the "integrity" or the "health" of the nation's ecosystems is a worthy goal, particularly given the evidence of adverse impacts caused by human activities. This consensus is reflected in our major environmental laws. But how do we know if we're achieving this important goal?

trout CEMAR's ecological indicators program has been working to answer this question, which is actually more challenging than one might think.

The challenge is that "health" is not an objective characteristic that can be measured, but a subjective assessment made by considering the status of indicators of important ecosystem attributes.


Temperature graph CEMAR's Climate Science Education program offers free presentations on climate science to interested organizations in the San Francisco Bay Area.

These strictly nonpartisan and nonpolitical presentations provide an opportunity for citizens to learn about the basic science of climate change. Given the importance of climate change to the future of the Bay Area, it is essential that the public hear from trained scientists in straightforward and nontechnical language.
