Thanks to your incredible support—we did it!

On June 20, 2025, Save the Redwoods League purchased the 1,517-acre Monte Rio Redwoods Expansion property and transferred it to Sonoma County Regional Parks for ongoing stewardship and eventual public access. Conserving this property links a contiguous conserved area of well over 22,000 acres (more than 34 square miles) of forest, wildlife corridors and watershed, from the Bohemian Highway to the Sonoma Coast and north to Jenner Headlands. It also comes on the heels of the League’s acquisition of the nearby Sonoma Coast Redwoods.

This development is a major win for redwoods, people, and the planet.

We’re proud to have worked hand in hand with Sonoma County Regional Parks and the Sonoma County Ag + Open Space District to make this milestone a reality, and we are deeply grateful to our key fundraising partners, the California Wildlife Conservation Board and Sonoma Land Trust.

The $24 million needed to secure the incredible Monte Rio property was generously provided by the California Wildlife Conservation Board, Sonoma County Ag + Open Space, the Gordon and Betty Moore Foundation, Sonoma Land Trust, and the Federated Indians of Graton Rancheria.

And of course, thousands of individual donors like you. Thank you!

The Monte Rio Redwoods Expansion acquisition is a major win for wildlife and people—helping stitch together a vital coastal corridor for both habitat and outdoor access.

Here’s why this land matters so much:

  • The purchase snaps the final puzzle piece into place, solidifying a vast, connected expanse of more than 34 square miles of redwoods, meadows, and streams between Sonoma Coast State Park and Monte Rio Redwoods Regional Park.
  • It fills a key gap in a vital wildlife corridor stretching along the coastal mountains from Marin County to Mendocino County.
  • It contains nearly four miles of Russian River tributary streams that provide critical spawning habitat for threatened coho salmon and steelhead trout.
  • It offers a chance to restore both the ecological health and cultural significance of the traditional lands of the Kashia Band of Pomo Indians and the Southern Pomo group of the Federated Indians of Graton Rancheria.

Because of our donors and partners, this incredible redwood forest is now public land. We’re honored to have achieved this milestone together, and we simply couldn’t do this work without your continued support.
