Mailliard Ranch

Protecting a nearly 15,000-acre landscape from future subdivision and development

Home to the largest coast redwood forest still in private family hands, Mailliard Ranch is a 14,838-acre undivided property near Boonville, California, in southern Mendocino. This expansive landscape features sweeping meadowlands, crystal-clear streams, and mountains and canyons blanketed by lush redwood forest, mixed-conifer groves, and oak woodlands. It has long been a puzzle piece to create more than 82,000 acres of contiguous protected lands. The ranch has nearly 1,000 acres of reserves, including old-growth coast redwoods, mature mixed-conifer forest, and salmon-bearing streams. A stronghold of biodiversity, it provides habitat for a wide range of rare and endangered plants and wildlife.

In partnership with Save the Redwoods League, the Mailliard family agreed to permanently protect this forest through three conservation easements, preserving the future of the old-growth redwoods and 28 miles of salmon-bearing streams at the headwaters of the Garcia River and in tributaries to the Navarro River. After securing conservation easements for the Mailliard west and middle ranches in December 2018, the League closed the final phase of this project in February 2021, protecting Mailliard east ranch, including the exquisite 58-acre old-growth Cathedral Grove. The Mailliards will retain ownership of the land and continue their exemplary stewardship of the forest, while the agreement safeguards the entire property from the threat of subdivision and development.

Completion of this project nearly doubles the amount of land that Save the Redwoods League has protected in Mendocino County. Read more at the links below.
