After more than a decade on POST’s GIS team, I’ve spent countless hours mapping the contours, watersheds and wildlife corridors of the Santa Cruz Mountains. But even after all these years, this range still surprises me. I’m constantly reminded how alive and dynamic these mountains are. I see it daily on my commute, during my weekend hikes, and in the fog rolling over the resilient redwoods. From the cool, shaded canyons of the north to the warm, open ridgelines farther south, this landscape is a mosaic of ecosystems that shape not just our local environment, but our lives and communities.

The Best in Biodiversity

Stretching from San Francisco to Monterey Bay, the Santa Cruz Mountains rise steep and forested from the coast. Fed by Pacific fog and rich in biodiversity, this is a land of contrasts. In the north, redwood groves, misty canyons, and shaded creeks offer a cool, green haven for millions of species. Farther south, sun-soaked ridges and oak-studded grasslands support a different, equally vital array of life. With its multitude of watersheds, the mountain range provides abundant clean water, essential for farming, fish, wildlife, and our health.

Shaped by Time, Protected by People

Have you ever hiked a ridgeline and wondered what histories the landscape has witnessed? With their long, resilient lifetime, the Santa Cruz Mountains hold countless stories. Shaped by powerful forces along the San Andreas Fault, these mountains are constantly changing. Their rocky layers preserve clues to a past filled with ancient oceans, earthquakes, and evolving ecosystems.

The range supplies local plants, animals, and people with a wealth of critical habitat, clean water, and natural beauty. But without decades of conservation work, much of this landscape could have been paved over and subdivided for luxury homes, golf courses, and other development. Instead, thanks to the tireless work of POST, our donors, and our partners, these lands remain healthy, well-managed, and welcoming.

For nearly 50 years, POST has helped protect key parts of the Santa Cruz Mountains, creating a connected network of open spaces across diverse terrain. From coast to canyon and ridgetop to redwood, protecting this range has required countless acts of vision, stewardship, funding, collaboration, and care. 

Steeped in time, the Santa Cruz Mountains carry generations of history. 

Places that Define Our Legacy

These landscapes in the Santa Cruz Mountains represent some of the many milestones in POST’s history. From beloved hiking trails to vital wildlife connectivity, they reflect the enduring impact of protecting more than 93,000 acres of open space across our region. The progress we’ve made is more important than ever in the face of a changing climate.
