Each of the past three decades has provided significant improvements in the equipment and methods used to harvest timber. We expect that the trend in mechanized timber harvesting will continue to increase to new levels in the 1980's. Some reasons for this projection and a few examples of new harvesting concepts will be described here. Before discussing these future needs, it is appropriate to review briefly the state-of-the-art of forestry mechanization.
