. Financial analysis of pruning ponderosa pine. Ponderosa pine Oregon Pruning; Ponderosa pine Washington (State) Pruning; Forest products Oregon; Forest products Washington (State). Conclusion Acknowledgments Metric Equivalents Figure 19—Break-even cost of pruning with historical and projected real prices and a 4-percent real interest rate, BLM Medford District. This pon- derosa pine 100-year site index 80 with thinnings regime was pruned at age 25. offset the price difference. On the other hand, the differences in appearance between currently available clear wood and clear wood from pruned young-growth trees available in the future are more significant in Douglas-fir than in ponderosa pine. It is likely that the existing moulding and millwork industry that uses ponderosa pine will readily accept clear wood from pruned ponderosa pine. Much of the clear Douglas-fir goes into the export market where its acceptance is less certain. We believe that the case is made that pruning ponderosa pine in some circumstances is likely to be an investment yielding returns in excess of the 4-percent real rate desired from resource investments on Federal lands. Information and computer software are available that can be used by foresters, silviculturists, and analysts to determine under what circumstances pruning of ponderosa pine is a financially attractive investment on their lands (Bolon and others 1992). We thank Robert Pierle and Robert Lewis, Medford District, Bureau of Land Manage- ment; Don Wood, Ochoco NF; and Jo Booser, Deschutes NF; for compiling yield data and cooperating in the design of the analyses. 1 inch = centimeters 1 foot = meter 1 cubic foot = cubic meter 1 acre = hectare 13.
