. A descriptive analysis of Montana's forest resources. Forests and forestry Montana Statistics; Timber Montana Statistics. Figure 3.—Ponderosa pine stand on Custer National Forest in eastern Montana. In the Douglas-fir climax zone, (fig. 4) stands grow moderately fast, are dense, and produce the most important commercial species in Montana: Douglas- fir, often mixed with ponderosa pine, western larch, or lodgepole pine. This zone occupies a large portion of the forested areas in the Montana Rocky- Mountains . The grand fir and cedar-hemlock climax zone, (fig. 5) the most productive forest land, with many moisture-loving species in the understory, is restricted to the northwest corner of the State. In the more moist and least disturbed areas of this zone, the climax species cedar and hemlock predominate. However, where disturbed by wildfire much of this forest zone is presently occupied by west err. larch, western white pine, and spruce. A mixture of species is common in this zone, but total acreage of the zone is small. The temperate spruce-fir zone (fig. 6) is also relatively productive. In the moistest portions, such as stream bottoms and poorly drained benches at moderate elevations, spruce is the only successful conifer. In other areas, subalpine fir is the probable climax species and lodgepole pine or western larch may be the dominant overstory trees. 3.
