We know forests are more than just trees. To increase recognition of the full value our timberlands offer, we developed a program to measure and report on 18 ecosystem services provided by our forests.

We share this information to help educate the public about the many benefits forests provide, to demonstrate transparency about additional revenue sources, and to serve as a leader in global reporting standards for ecosystem services.


These are tangible benefits provided by an ecosystem, such as food or timber.

Some ecosystem services provided by our timberlands do not lend themselves to annual reporting due to a lack of quantitative measures, insufficient reporting units, or the service having been recently discontinued. These services are important reflections of the value provided by our timberlands and could lend themselves to fuller description in the future, if not annual tracking.
