California Timberlands

Our California Timberlands are situated along the state's spectacular North Coast, with a chip facility on Humboldt Bay and a tree nursery in Korbel.

These lands border mountains that are lush with giant redwood forests, which are an important part of the region’s heritage and our business in the area. Our management practices in the state are certified under rigorous Forest Stewardship Council® standards. These standards shape our regional management strategy, along with our engagement with state and federal officials, tribal neighbors—such as the Yurok—and other area stakeholders.

Our California operations have a long legacy of research and conservation to protect threatened and endangered species. This work began with our studies on the northern spotted owl and has expanded to include many other wildlife, aquatic and plant species. We are also an active member in the California-regulated carbon markets—managing two of the largest such projects in the U.S. Other focuses include water management and wildfire mitigation to ensure long-term forest health and community resilience.

Public Access

The majority of our California Timberlands are closed to the general public. On these closed lands, only current and former Green Diamond employees and permitted organizations may access lands for recreational uses. Community organizations, school groups and members of the public may inquire to schedule hosted field tours.

There are currently two recreation opportunities on our California Timberlands that offer permitted recreational access for the general public.

  • Willits Woods - The Willits Woods Permit Program is located on a 19,000-acre property that is located 6.5 miles west along State Highway 20 from the town of Willits, California. It comprises both forested and woodland prairie habitats and contains a wide range of wildlife species. The land is a sustainably managed working forest where harvesting and reforestation activity will be regularly occuring. This program offers several different recreational permits to enter and enjoy hiking, biking, exploring, non-commercial berry and mushroom picking, ATV riding and other outdoor activities. It offers individual and family permits with both motorized and non-motorized access options. A limited number of hunting permits are also available. For more information on specific permit availability, pricing, rules, and regulations, please visit the "My Outdoor Agent” online sales platform.1
  • Camp Bauer, our picnic grounds located in Korbel, California, is available for lease to the public by reservation only. This facility includes an outdoor kitchen pavilion with electricity and non-potable water, restrooms, picnic tables, BBQ pit, horseshoe pit, and baseball field. To learn more about this facility, please call (707) 668-4401 or email

1 Green Diamond Resource Company has partnered with My Outdoor Agent (MOA), a digital platform that connects landowners with outdoor enthusiasts looking for unique recreational experiences. Through MOA, which is created and managed by Orbis, Inc., a variety of Willits Woods Recreational Permits are available for purchase. The MOA platform (including digital apps for iOS and Android) provides permittees with the ability to securely purchase permits, view property maps, receive important information about area closures, and more.

Conservation Plans and Permits

The North Coast of California is home to many unique species and habitats. For decades, we have initiated programs to research and protect the region’s biodiversity. In 1992, we signed the first-ever habitat conservation plan (HCP) on private timberlands to protect the northern spotted owl. In 2007, we established an aquatic habitat conservation plan (AHCP) to protect several fish and amphibian species. In 2018, we entered into a Safe Harbor Agreement with the California Department of Fish and Wildlife for the conservation and recovery of the Humboldt marten, and in 2019, the U.S. Fish and Wildlife Service approved our Forest HCP.

Forest Habitat Conservation Plan (HCP):

Covers 358,626 acres to protect the Pacific fisher, red tree vole, Sonoma tree vole and northern spotted owl from 2018 through 2069. Conservation strategies include creating and maintaining a mosaic of forest age classes to meet owl habitat requirements; protecting highly productive owl sites; promoting late seral habitat elements with riparian and geologic prescriptions; creating snag and wildlife tree prescriptions; conducting pre-harvest surveys and seasonal protection of nesting owls; protecting known occupied fisher den sites with a 0.25-mile disturbance buffer; covering structures that pose an entrapment risk to fishers; conducting barred owl removal experiments; and monitoring, reporting and adaptive management.

Aquatic Habitat Conservation Plan (HCP):

Covers 358,594 acres to protect the coho salmon, Chinook salmon, steelhead trout, coastal cutthroat trout, southern torrent salmon and tailed frog from 2007 through 2057. Conservation activities include riparian prescriptions; road management measures; unstable slope prescriptions; harvesting prescriptions to minimize ground disturbance; and monitoring, reporting and adaptive management.

Humboldt Marten Safe Harbor Agreement (SHA):

Covers 363,967 acres to protect the Humboldt marten from 2018 to 2057. Conservation strategies include assisted dispersal commitments; special management and no-harvest reserve areas; AHCP riparian prescriptions; snag, slash pile and wildlife tree prescriptions; protection of known natal and maternal den sites with 0.5-acre buffer; coverings of structures that pose an entrapment risk to martens; and monitoring, reporting and adaptive management.
