Preserving Redwood Forests Since 1900

Our Mission

Sempervirens Fund protects and connects the redwood forests between Silicon Valley and the Pacific Ocean — and helps keep local parks open. Let's enjoy the incredible local redwood forests that have thrived here for 20 million years — and leave a wonderland for future generations of people and wildlife!

Our Vision

We envision a permanently protected, forested, collaboratively managed, continuous ecosystem covering the Santa Cruz Mountains of California, with extensive trails, picnic and camp sites, landscapes, and scenic vistas. To make that vision a reality, we cooperate with other land conservation organizations and public agencies to make strategic land purchases that create, expand, and link together local redwood forests and parks.
