. A descriptive analysis of Montana's forest resources. Forests and forestry Montana Statistics; Timber Montana Statistics. Timber Harvest Levels The modern era of timber harvesting began after World War II when the in- dustry expanded to meet pent-up housing demands. During the past two decades, product makeup has changed. Use of wood for fuel and miscellaneous products has declined, sawlog output has increased, and plywood, pulp and paper, and particle- board have been added to Montana's product mix. Since 1952, the total output of Montana roundwood products (all products except firewood) has more than doubled (fig. 18). In the past 20 years, the annual removals from growing stock on Montana forests increased from just over 100 million cubic feet to nearly 300 million cubic feet. Sawlogs have been the most important segment of this harvest. During the past 20 years, Montana has gone from a sizable surplus of sawlogs to constant pressures to increase harvesting. From the viewpoint of increasing total timber output, accelerated harvesting has been generally desirable because mortality in old-growth stands is high and the increased harvesting has utilized some of this material before it deteriorated. Total harvest in Montana has fluctuated from about billion board feet to about billion board feet in recent years (fig. 19). Most of the fluctua- tion has been on public lands, primarily on National Forest lands. National Forest harvests have averaged 85 to 90 percent of the total public land harvest, and one-half to two-thirds of the total 1952 '54 '56 '58 '60 '62 '64 '66 '68 70 Year Figure 18.—Output of Montana roundwood products. 31.
