Green Diamond Management Company

Our roots run deep. Through Green Diamond Management Company—a wholly-owned subsidiary of Green Diamond Resource Holding Company—we responsibly manage over 586,770 acres of highly productive working forests in the Southeast and Pacific Northwest.

These timberlands make up the Twin Creeks’ timber asset portfolio, which includes 496,000 acres in our Southeast footprint and nearly 90,773 acres of working forestlands in the Columbia Basin Management Area on the Washington-Oregon border. Both are managed in accordance with Sustainable Forestry Initiative® (SFI) standards, the largest forestry certification program in North America.

Twin Creeks Timber LLC (“Twin Creeks”) was created in 2015 through a joint venture formed by Green Diamond and Silver Creek Capital Management (“Silver Creek”), a $6.3 billion alternative investment manager, to enable institutions to directly invest in high-quality timber assets alongside a timberland manager. Twin Creeks was founded with a distinctive strategy for institutional timber ownership, connecting sophisticated investors directly with an experienced operating partner.

Green Diamond, with its longstanding reputation as a leader in the forest products industry, plays a central role in this partnership. We value our investment in and management of Twin Creeks, recognizing strong alignment between Twin Creeks’ business model and our own stewardship approach. Green Diamond Management Company welcomes further opportunities to collaborate with individuals and institutions interested in the ownership and responsible management of natural capital assets.

Southeast Timberlands

Our Southeast footprint extends across Alabama, Florida, Georgia, Mississippi and South Carolina, where we provide landowners and their investors with a comprehensive suite of forest management services. Our goal is to be a preferred provider of SFI-certified forest products by partnering with landowners and investors who align with our sustainable forest management approach.

The services we provide include:

  • Managing working forests to maintain and enhance their long-term health and productivity.
  • Providing marketing and sales expertise to ensure value for forest landowners.
  • Supporting the evaluation, acquisition and sale of forestlands.

Public Access

We prioritize public access across much of the Southeast timberlands through our Recreational Lease Program. The program features 350,000 acres of working forestlands in Alabama, Georgia, Mississippi and South Carolina, where we offer opportunities for hunting, camping and other activities as allowed under state, county and municipal guidelines. Learn more about our online Recreational Lease Program and how to create or access an account.

Conservation Plans and Permits

Because our Southeast operations are so widely distributed, they encompass a diverse variety of plant, fish and wildlife species. As we work to protect these species and the habitats they rely on, we apply management best practices in line with SFI standards. We also ensure compliance with all state and federal regulations, including Endangered Species Act (ESA) take-avoidance policies. In Georgia, Alabama and South Carolina, we work with state officials to support Wildlife Management Areas that conserve and enhance wildlife habitats and enable public access for outdoor recreation.

Columbia Basin Management Area Timberlands

Scattered along the Cascade Crest, our Columbia Basin Management Area (CBMA) offers views of Mount Adams and Mount Hood and is situated near prominent river corridors, including the Columbia and White Salmon. Tree species include Douglas fir, ponderosa and lodgepole pine, true firs and western larch.

Guided by our SFI® certification, we work to continually improve the sustainable management of these forests for the long term. We work with state and government agencies and local tribes—including the Confederated Tribes and Bands of the Yakima Nation—to protect cultural resources, fish and wildlife, and mitigate wildfire risks. Much of the region is covered under a Safe Harbor Agreement (SHA) to protect the northern spotted owl.

We also manage several harvest units in the area, which create job opportunities in local rural communities and provide a variety of wood species to nearby mills.

Public Access

More than 80% of our CBMA lands are open for free, public access, providing visitors with opportunities to bike, hunt, fish, hike and explore. The area includes the Washington counties of Klickitat, Skamania and Walla Walla, as well as the Oregon counties of Hood River and Wasco. A small percentage of land is leased for private recreation. For additional guidelines on public access in these areas, view our FAQ.

Please note, most TCT lands are open for general non-motorized recreation.

Conservation Plans and Permits

The CBMA is rich with diverse plants, fish and wildlife, which we work with government agencies and local conservation groups to protect. Our conservation efforts include a Northern Spotted Owl SHA, formed between the U.S. Fish & Wildlife Service and the previous landowners in 2012, that covers 45,000 acres in Southern Washington and Northern Oregon. Green Diamond has also partnered on projects such as remediating a local bat cave and restoring high-priority fish passageways on Tony Creek.

TCT-Three Rivers Northern Spotted Owl Safe Harbor Agreement (SHA):

Covers 43,375 acres to protect the northern spotted owl from 2012 through 2072 (permit assumed in 2021). Conservation strategies include setting aside land and deferring harvest within northern spotted owl sites; planning for a 60-year average harvest rotation; implementing silvicultural provisions to create and maintain a mosaic of forest age classes; and implementing snag and wildlife tree prescriptions.

Twin Creeks Timber South ESA Compliance:

Ensures sustainable forest management in accordance with state best management practices, SFI standards and ESA take-avoidance policies.
