Be an environmental activist for the central Sierra Nevada

Help CSERC protect the environment by signing up as an activist. Together we defend water, wildlife and wild places in the Northern Yosemite and the central Sierra Nevada region.

“Be an engaged citizen on environmental issues that matter”


Let’s join our forces

Activist AlertMany of CSERC's key victories come when we get enough activists to write letters, make phone calls, or speak at public meetings about issues of concern. We need your pen, e-mail, or voice!


When do we need environmental activists?

CSERC reviews all local development proposals and projects on public lands so we don’t miss an opportunity to defend the environment, but we have no way of knowing when a controversial issue will arise.

No matter the timing, the issue is always urgent and your voice is very much appreciated.


Sign up to be an environmental activist.

If you sign up as an environmental activist you will receive the latest update action alerts by e-mail. Then you can always decide whether you have the time when we e-mail you and if it is a project that you have concerns about. There is no obligation once you sign up.

If you want to receive alerts when you can raise your voice as an activist for an issue you care about, then please contact CSERC's executive director John Buckley, at and let him know you want to receive future activist alerts.
