MOUNT RAINIER The Forests of Mount Rainier National Park

LODGEPOLE PINE (PINUS CONTORTA)

Lodgepole pine (fig. 17) is widely distributed from Alaska to Lower California and eastward through the Rockies to Dakota and Colorado. It occurs sparingly in the park up to 5,000 feet above sea level. It adapts itself easily to the different conditions of soil, moisture, and exposure.

Fig. 17.—Lodgepole pine (Pinus contorta), 60 inches in diameter.

This tree varies greatly in the different regions where it is found. About Mount Rainier it does not often exceed 20 to 40 feet in height and is often a much smaller tree. It produces cones at the age of 5 to 7 years. The foliage is a yellowish green. At high elevations the leaves have a peculiar whorled appearance which gives it a different aspect from that of the other pines. The short, heavily limbed trunk bears no resemblance to the tall and slender shaft of the lodgepole pine of the Rocky Mountains. The root system is shallow and the tree is very easily fire killed. The wood of the variety which grows in the park is of no commercial value.
