The work

What they do

Protecting and restoring wild places across California.

Every year they sign one sentence and file it with the federal government: “CalWild protects our state's drinking water and wild places by seeking new protections for streams and natural areas on public lands. Current campaigns include: the Sierra Forests, NW CA, the Desert, the San Gabriel Mts and the Central Coast of California.”

DEFENSE: CalWild organized public pushback against multiple proposed policies and actions which would be damaging to California's federal public lands through action alerts, grassroots organizing and direct advocacy. A highlight was the key role CalWild played in summer of 2024 to convince California Republican member of Congress to oppose inclusion of selling off public lands in the 2024 "Big Beautiful Bill". This opposition meant that proponents did not have the votes to include sell-offs in the bill, and they were stripped out.

Honesty note: leadership comes from each year’s federal filing, so it can run a year behind. This one caught a changing of the guard in the act: the FY2025 officer table lists Mariana Maguire, the return itself is signed by Mark Green. Orgs that claim their page can update it same-day.

Those 12 volunteers are people who decided this ground was theirs to defend. If CalWild is fighting for your place too, the matchmaker will find your way in.
