Company Overview

Explore a Working Forest

A working forest is more than just trees. It’s a place for creatures, big and small. It’s a place for clean, cool water for people and fish. It’s a refuge. It’s a home. It’s where homes come from.

Green Diamond Resource Company has taken care to protect and nurture such forests for over a century. We pride ourselves on our stewardship principles and our longstanding commitment to environmental excellence. Our commitment to sustainable forestry shows in everything we do, whether planning a harvest, replanting for the future, or nurturing the trees that provide our livelihood.

Working forests balance environmental and economic values, assuring that generations to come will enjoy the bounty nature has provided and the wood products that enrich our lives. Green Diamond – setting the standard in working forests™.


About Us

Green Diamond Resource Company is a fifth-generation, family-owned forest products company. We own and manage working forest land in 10 states in the western and southern US. A few important facts:

  • We operate under the toughest forest practice regulations
    found anywhere – regulations developed to protect water
    quality, soils, fish, wildlife species, sensitive plants
    and archeological and cultural sites.
  • Our Washington, Oregon and Southern timberlands are independently certified to be in compliance with the Sustainable Forestry Initiative® (SFI) Standard.
  • In California, Green Diamond Resource Company lands have achieved Forest Management certification under the Forest Stewardship Council® (FSC®) standards
  • We harvest less than 2% of our lands annually; all harvested areas are quickly replanted with native species to start the forest cycle anew.
  • These vibrant, working forests improve water quality, provide habitats for many fish and wildlife species and store carbon in both trees and in the quality wood products these forests produce.
  • In 1992, we were the first company to receive approval for a Habitat Conservation Plan (HCP) for the Northern Spotted Owl. In 2007, we obtained approval for an HCP that protects seven aquatic species on our lands in California.
  • Multi-species Habitat Conservation Plan that protects 51 fish and wildlife species on our Washington lands was approved in 2000.
  • Ethical conduct is expected of everyone who serves Green Diamond - our Board, officers, managers, employees, and contractors. It is a tradition that has endured for more than a century and one that will drive our success for future generations. We take pride in our "In the Clear/Out of the Bight" Code of Conduct.
  • We are active in our operating communities, through monetary contributions and in-kind service to a variety of health and human services, environmental and arts initiatives.
