The objective of this study is (1) to design a timber harvesting system for dry-belt Douglas-fir located on critical mule deer winter range; and (2) to test the system's compatibility with maintaining the carrying capacity of the range for deer. In 1983, a small area of the Knife Creek winter range was selectively harvested resulting in the removal of only 13% of the merchantable Douglas-fir volume. Although initial responses to the results of this experiment were positive, the operation was not economically viable. Refinements were made in 1984 including a shift from the mark-to-cut approach to the more efficient fallers selection method of determining which trees to harvest. During the spring of 1984, this revised system was applied on a larger area within the winter range. An assessment is in progress.
