About Us



Sempervirens Fund’s mission is to protect and permanently preserve redwood (Sequoia sempervirens) forests, wildlife habitat, watersheds, and other important natural and scenic features of California’s Santa Cruz Mountains, and to encourage public appreciation and enjoyment of this environment.

Sempervirens Fund protects, connects and cares for the local redwood forests between Silicon Valley and the Pacific Ocean – while we open up more ways for people to enjoy them. Since 1900, Sempervirens Fund has permanently protected more than 54 square miles of local redwood forests and watersheds for people, wildlife and future generations.

As California’s oldest land trust and the only organization focused entirely on this local redwood forest, Sempervirens Fund works on behalf of the community to re-establish a vast, beautiful, accessible redwood world that provides crucial refuge and recreation in our own backyard. We call it the Great Park.

The Great Park ultimately will cover 195 square miles of public parks and private land. That’s the size of four San Franciscos. More than 2/3 of this land is already protected…permanently. Yet, 1/3 of the forest is at risk of being cut up, fenced off and paved for housing subdivisions, shopping centers and urban sprawl.

We carry on the work of our founders — local residents who stood up and saved the last old-growth redwoods in the area. In the late 1800s, they watched in horror as 300 square miles of ancient redwood forests blanketing the Santa Cruz Mountains were logged down to bald hills. What could they do?

They joined together and protected the largest remaining area of old growth forest, which became Big Basin Redwoods State Park in 1900.

Since then, Sempervirens Fund played a crucial role in creating three other local redwood parks: Castle Rock, Butano and Portola Redwoods. Recently, we stepped in to keep Castle Rock State Park open and began building top-notch facilities that will put the park on solid financial footing.

Now is the crucial last chance to re-create an incredible, life-giving redwood forest for people, wildlife and future generations.

Join Sempervirens Fund to connect the existing parklands, provide more wildlife habitat, open up new trails and care for the redwood forest. Together we’ll keep local trails and campgrounds open so we all can hike, bike, camp, explore and enjoy a wild respite from our busy Bay Area lifestyle.

Join us – and please, go out and enjoy the redwoods soon!

By rallying people throughout the community, Sempervirens Fund can move quickly right now to buy more land and conservation easements – to protect old-growth redwoods and create the Great Park where we all can enjoy:

  • 2,000-year-old redwoods – the tallest tree on Earth
  • 20 million-year-old redwood forest, growing here and nowhere else
  • Clean air, fresh water and stunning waterfalls
  • Abundant wildlife – like coyotes, salmon and endangered marbled murrelets
  • Extensive trails, campgrounds and picnic spots
  • Quiet, awe-inspiring places to reconnect with the wild and re-energize ourselves
