The single-grip harvester and small skyline yarder appear to be a feasible combination of logging equipment that, with careful planning, work well on level ground. Results of this case study indicated a cost-effective operation with revenue of $103,258 and cost of $78,810. However, a major factor in the revenue generated was the sawlog material that came from the green standing trees (28% of the total volume contributing 57% of the total revenue); the pulp material alone was logged at a net loss. Fuel reduction objectives were effectively met, particularly in the intermediate (3-20 in.) size classes. Area of "heavy use" soil disturbance averaged 6.5%, and occurred primarily in yarding corridors-the use of appropriate intermediate supports on the skyline yarder is recommended. Soil bulk densities were generally higher in the logged areas (4-6%), although a statistically significant difference was recorded only at 8-in. depth in unit 2. This degree of soil disturbance and compaction is unlikely to cause long-term environmental problems at Deerhorn.

This case study indicates that fuels reduction objectives can be met with a mechanized harvest system that is economically feasible and environmentally sensitive. Changing the size distribution of fuels, without entirely removing them, is a tactic that can accomplish three objectives simultaneously: 1) reduce fire risk, 2) preserve structure for dependent wildlife species, and 3) leave nutrients on site to help maintain long-term site productivity. The Deerhorn case study has demonstrated that it is possible to manage individual sites as integrated, multiple-component systems, a key feature of ecosystem management.
