March for Science – April 22

Join the Alameda Creek Alliance at the San Francisco March for Science on Earth Day, Saturday, April 22nd, from noon to 4 pm.

The March for Science is a call to support and safeguard the scientific community and science-based decision making. Recent Trump administration policy changes have caused heightened worry among scientists. The mischaracterization of science as a partisan issue, which has given policymakers permission to reject overwhelming evidence, is a critical and urgent matter. It's time for people who support scientific research and evidence-based policies to take a public stand and be counted.

Science is a method to study the physical and natural world with observable physical evidence as the basis of that understanding. Science has guided the activities of the Alameda Creek Alliance and the restoration of steelhead fisheries in Alameda Creek since our inception in 1997. Science has helped us to answer such questions as, “Can the Alameda Creek system support a steelhead fishery?” (YES!), “How large of a population can the system support?”, “Where is the best habitat located in the Alameda Creek watershed?”, and “When are creek flows adequate for steelhead to exists in the system, how does this match with the life cycle of the fish, and what changes could be made to water management to support steelhead recovery?”

The March for Science is an international movement, led by organizers distributed around the globe. Join us this Earth Day in San Francisco to march in support of science! More information to come.
