Forests provide aesthetic, ecological, economic, recreational, and spiritual values to society. When people see trees harvested, they may need assurance that the harvest is not “destroying” the forest. Forest certifi cation reassures them with a third-party evaluation of the management of a particular forest, assuring the public that the benefi ts and functions of the forest, including clean air and water, wildlife and plant habitat, soil protection, recreation, and more, are enhanced or protected during management and harvest.
