    made of Douglas-fir wood were excavated from archeological sites in New Mexico dating back to the Anasazi. The White Mountain Apache used the pitch of this conifer as gum and applied it to water jugs to make them watertight. Douglas-fir roots were used in California Indian basketry. Commercial: The tree is one of the world’s most. Studies with Douglas fir seedlings suggest that, at least in this species, the source of root growth stimulus is the leaves (Lavender et al, ; Lavender and Hermann, ; Lavender and Wareing, ). Ritchie (unpubl.) found that bud removal had only a modest effect on.

Characteristics. Rocky Mountain Douglas-fir is a large tree, typically reaching 35–45 m (– ft) in height and 1 m (3 ft 3 in) in diameter, with exceptional specimens known to 67 m ( ft) tall, and 2 m (6 ft 7 in) in commonly lives more than years and occasionally more than 1, years.

The bark on young trees is thin, smooth, gray, and covered with resin : Pinopsida. A broad-pyramidal tree with soft bluish-green foliage when crushed emit a camphor scent. Moderate grower doing well in most locations. Likes full sun and relatively dry locations.

Douglas fir belongs to this group and that its chilling requirements are satisfied by a period of 8—12 weeks of temperature between 3 and 60 C. Presumably, the low tempera- tures initiate the hypothesized sequence in concentration of growth by: GENERAL BOTANICAL CHARACTERISTICS: Coast Douglas-fir is a large, coniferous, evergreen tree.

Adapted to a moist, mild climate, it grows bigger and more rapidly than the inland variety. Trees 5 to 6 feet ( cm) in diameter ( cm) and feet (76 m) or more in height are common in old-growth stands [].These trees commonly live more than years.

Blue Douglas Fir (Pseudotsuga taxifolia glauca) The Blue Douglas Fir is considered one of the noblest forest trees, very ornamental, an excellent specimen for grouping or mass planting. Best planted in dry, windy areas of the midwest. It makes a nice short needle Christmas tree.

The Rocky Mountain Douglas Fir can reach heights of 40 to 80 feet. Effects of watering treatments on germination, survival, and growth of Rocky Mountain Douglas Fir: a greenhouse study by Noble, D.L; Edminster, C.B; Shepperd, W.D; U.S. Rocky Mountain Forest and Range Experiment StationPages: Responses of Douglas-fir seedlings were studied for 3 yr following eight vegetation-control treatments in three western Oregon clearcuts.

The objectives were to determine seedling growth response to different areas of spot vegetation control and to determine the relative influence of early woody and herbaceous competition on seedling growth. Besides Douglas fir, other possible names include Doug-fir, false spruce, red fir, Oregon pine, Douglas pine, yellow fir, and Douglas spruce.

Pseudotsuga menziesii var. menziesii is the coast Douglas fir. Pseudotsuga menziesii var. glauca may be called either the interior Douglas fir or the Rocky Mountain Douglas : Vanessa Richins Myers. Abstract. Seedlings (transplants) of 2+1 Sitka spruce (Picea sitchensis (Bong.) Carr.) and 1 + 1 Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) were grown in a nursery at the Bush Estate, Scotland.

Batches were lifted and Cited by: Douglas Fir Pseudotsuga menziesii. This tree is native to the forest and used primarily for its lumber. It has short, thin needles that are shiny and green. This fir tree grows into an open pyramidal form.

The upper branches grow upright and the lower branches descend. It will grow to be 60′ tall and 20′ wide.Classification of the forest vegetation on the National Forests of Arizona and New Mexico. Res. Note RM Fort Collins, CO: U.S.
