The concept of sustainability is sometimes elusive, but an examination of the etymology of the word and the history of its application in forest management helps pin it down. Sustainability becomes a concern when a growing human population begins to deplete resources beyond expected rates of renewal. As used today in forest management, the term means maintaining the forest for a long time, showing concern for the well-being of future generations, making reasonable estimates of future needs, knowing current rates of resource use and regeneration, and reaching consensus on appropriate levels of resource use. Six case studies, which may or may not address all those elements, are offered as a starting point for discussion, and an annotated bibliography opens avenues for further study.
