For example, evidence exists for "aspect races" in variety menziesii: Seedlings grown from seed collected on the more xeric southern aspects grow slower, set buds earlier, and form larger roots in relation to shoots than seedlings grown from seeds collected on adjacent north-facing slopes. The flat leaves are 2-4 cm in length, taper to a short petiole, with two whitish bands on the lower surface. Natural vegetation of Oregon and Washington. For this reason, we considered only the first two pairs of composite traits and environments in subsequent analyses.
A significant portion of the sedimentary rocks is limestone, which gives rise to neutral or alkaline soils ranging in texture from gravelly loams to gravelly silts. Franco, called Rocky Mountain or blue Douglas-fir. Limestones often weather into soils that are excessively well drained.
Large numbers of pollen or seed cone buds in the fall merely indicate the potential for a heavy cone crop the following year. Abstract Height growth patterns from several published site curve sytems for ponderosa pine Pinus ponderosaDouglas-fir Pseudotsuga menziesii var glaucawestern larch Larix occidentalis and lodgepole pine Pinus contorta var latifolia were compared to stem analysis data from western Montana.

Growth intercept models are expected to be developed for all commercial species in British Columbia.
Approximately 2,000 species of fungi have been identified as potential symbionts with Douglas-fir, and both ectomycorrhizal and ectendomycorrhizal structures have been observed on this species 59.
