“…8) suggest that these species respond differently to the soil conditions produced by the different rock types. Gail and Long (1935) showed that Pinus contorta growth increased with increasing aeration of the soil. The coarseness of granitederived soils allows for more aeration than the heavier sedimentary-derived soils.…”

The vegetation of the Big Horn Mountains is typical of the Central Rocky Mountain region; a lower Juniperus osteosperma zone is followed by Pinus ponderosa, Pseudotsuga menziesii, Pinus contorta, and Picea engelmannii—Abies lasiocarpa zones. Rock or geologic substrate type has a strong influence on forest vegetation. On sedimentary areas forests cover less that 50% of the area and are composed of Pseudotsuga menziesii or Picea engelmannii—Abies lasiocarpa. On granitic substrates forests cover over 80% of the surface and are composed chiefly of Pinus contorta with Picea engelmannii—Abies lasiocarpa at higher elevations. Populus tremuloides is present but unimportant as a vegetation type. Most of the rainfall comes during March, April, and May; precipitation is less than 30 mm per month during summer. Thus soil—water relationships are important in determining vegetation pattern. Precipitation comes from the east, which allows forest vegetation to reach lower elevations on the east than on the west slope.

“…Seedling production in containers may have negative effects on root structure due to vertical shaping (Kinghorn, 1978) Kinghorn, 1978;Preisig et al, 1979;Carlson et al, 1980). However, Lindstrom (1990) (Cheyney, 1929;1932;Gail and Long, 1935;McQuilkin, 1935;Day, 1945). However, due to cavity size and shape, roots of containerized seedlings are inadvertently trained to grow vertically, not horizontally.…”

Summary — Root system morphology and growth of Douglas fir (Pseudotsuga menziesii var glauca (Beissn) Franco) and Lodgepole pine (Pinus contorta var latifolia Engelm) saplings transplanted from containers to the field in 1979 were compared with naturally-regenerated saplings of the same species and age. Naturally-regenerated saplings of both species were significantly taller than planted trees, had greater leader growth in the previous year and height/diameter ratios, and smaller taproot diameters 10 cm below groundline. Naturally-regenerated saplings also had up to 2.3-fold the number of lateral roots compared with planted saplings. Seventy to 79% of all primary lateral roots of naturally-regenerated saplings occurred within the top 10 cm of the soil surface, compared with 30-42% for the planted trees. The depth of the first structural lateral root associated with naturallyregenerated saplings was also significantly less than that of planted saplings.

“…The amount of root development was shown by Biswell (1935), Cannon (1923), Cannon (1924), Cannon and Free (1925), Loehwing (1931 a, b), and Gail and Long (1935) to he influenced by aeration and air content; poor aeration, which tends toward low oxygen and high carbon dioxide content, resulted in smaller amounts of growth than under wellaerated conditions. The different aeration condition;; of the three soils of this study probably did not cause the differences in the root rlevelopment of uninjured seedlings growing in the three soils, because root rlevelopmrnt was greatest in Orange soil where aeration, as indicated by air space, has been shown to be least favorable anrl therefore should have restricted root rlevelopment.…”
