S. Macdonald, 1972 . | 2 Sustainable Forest Management Whatever relationship people choose to adopt with the environment in the years that lie ahead science and technology as typified by the development of remote sensing will increasingly be called upon to meet the crisis of choice so clearly embodied in the rate at which we exploit our resources develop new industrial strategies and seek to protect the quality of life. D. S. Macdonald 1972 DEFINITION OF SUSTAINABLE FOREST MANAGEMENT Forest management is necessary because of human needs to balance 1. The flow of values from the forest and 2. An unimpaired ability to continue providing those values. In its present form forest management adopts a position identical to that of any management activity designed to accommodate a large open system forest management is comprised of conscious human actions that lead to a goal. Broadly speaking the goal of forest management has almost always been stated as the continued flow of benefits from forests to satisfy present and future human needs. In some areas management is needed to ensure the continued existence and future productivity of the forest in any form. In others forest management is an ancient practice. Thus in many forests the results of some of the earliest forest management practices have been known for years in others they are only now becoming available to be assessed. In the goal at least there seems to exist a remarkable degree of consensus. The most recent innovations in forest management conform to a sustainable forest management approach. A key facet of this approach is the use of new forestry practices that satisfy the expressed desire or goal that forest management succeed in maintaining forest ecosystems in a sustainable condition that is that human activities in the forest do not negatively affect the ability of the forest to continue in virtually the same way as before. Obviously such a goal is highly idealized for 2001 CRC Press LLC example the effect of natural climate .
