Western white pine (Pinus monticola) is a large tree, regularly growing to 30–50 metres (98– ft) and exceptionally up to 70 metres ( ft) is a member of the white pine group, Pinus subgenus Strobus, and like all members of that group, the leaves ('needles') are in fascicles (bundles) of five, with a deciduous sheath.

The needles are finely serrated, and 5–13 cm (2–5 in) : Tracheophytes. Photo Credit Cover Photo: Old growth western white pine circacourtesy of the Latah County Historical Society. The photo, No.is apparently one of a series taken by the American Lumberman on or about Septem about 1/2 mile west of Collins (4 miles north of Bovill, ID).

value, western white pine is inventoried by itself in forest statistics. In consid - ering the western white pine type, how - ever, only those stands containing a majority of sawtimber volume or sap-ling stems are classified as this type.

In most lumber and plywood products western white pine is marketed under its own name or as Idaho white : David P. Lowery. The western white pine is an ornamental species of tree that is blessed with an incredible endurance capacity. The beautiful coniferous tree has an open crown.

Western white pine grows rapidly to a large size; one of the largest standing trees measures cm ( in) in d.b.h. and m ( ft) tall in the mountains near Medford, OR.

The western white pine was named by David Douglas in while on a journey exploring the west coast of North America. on white pine seeds, bark and needles. White pine stands also provide shelter for moose, bear, grouse, woodcock, songbirds, birds of prey and small mammals.

TREE SHAPE The shape of eastern white pines depends on whether they grow in an open field or in a sheltering stand. In the open, white pine. Light intensity related to stand density in mature stands of the western white pine type.

Jour. Forestry 46(l):l 2 - SILVICULTURE U u Boe, K. Composition and stocking of the young stand 35 years after a selective cutting in ponderosa pine. A disease, causing severe flagging of young western white pine (Pinus monticola Dougl.), was investigated at Hill Siding and Arrow Park, British Columbia.

The primary symptom of the disease was flagging of twigs, resulting from a rapid necrosis of terminal shoots and less commonly from girdling-lesions on 2-year-old growth. A small percentage of the severely flagged trees died. Damaging. Western white pine (Pinus monticola) is a common associate throughout the Sierras.

Other associated species include limber pine (Pinus flexilis) in the southern Sierras, whitebark pine (P. albicaulis) in the northern Sierras, foxtail pine (P. balfouriana) from Mineral King to Kersarge Pass, and mountain hemlock (Tsuga mertensiana) north. The Inland Northwest has 21 million hectares of productive forestlands, which have a large contribution to state and regional economies.

Wood harvested in Idaho in resulted in 18, jobs, $ million in wages and salareis, and $ billion in sales and services. In order to maintain and increase the economic impacts of Inland Northwest forests, it is vital to ensure forests remain. Young sapling and pole size stands respond better to thinning.

Lodgepole pine stands should only be thinned between the ages of 15 and 30 years old since older stands do not respond well.

Where usable or salable specialty products (logs, post, poles, or Christmas trees) are to be cut, they will be removed in a manner that will maintain or. The distribution of western white pine has dramatically declined. In Idaho, for example, the historical (circa. ) areas covered by western white pine forests (map 1) compare markedly to those of today (map 2).

Each map shows only stands with a composition greater than 15 percent western white pine with a minimal mapping unit of a square. Ponderosa pine occurs in pure stands or may be mixed with lodgepole pine, grand fir, Douglas-fir, western larch, western white pine, incense-cedar, white fir and quaking aspen.

Ponderosa pine forests are widely distributed in eastern Oregon, ranging in elevation from 2, to 6, feet. The emerging predominance of western white pine on MD-GNP, especially in mid- and high-elevation stands, resulted from several interacting factors: (1) survival —fires increased in warming climates and with lower levels of higher suppression, and western white pine is better able to survive fire than many other conifer species in the.

Eastern white pine (Pinus strobus L.) is a highly valuable tree species providing several ecosystem services, notably to Indigenous people [1][2] [3].Once an important component of northeastern. Line surveys were conducted in 13 young western white pine (Pinus monticola D.

Don) stands throughout British Columbia to determine the effectiveness of lower branch removal in controlling blister. (For comparison, western white pine and western larch are and % of tree dbh, respectively). Grand fir has a well-developed taproot [14,].

On dry sites the taproot grows to moderate depths while on moist sites shallow lateral roots prevail, and the taproot may be absent. Pinus albicaulis, known by the common names whitebark pine, white pine, pitch pine, scrub pine, and creeping pine, is a conifer tree native to the mountains of the western United States and Canada, specifically subalpine areas of the Sierra Nevada, Cascade Range, Pacific Coast Ranges, and Rocky Mountains from Wyoming northwards.

It shares the common name "creeping pine" with several other. The White Pine Series of Architectural Monographs, subtitled "A Bi-Monthly Publication Suggesting the Architectural Use of White Pine and Its Availability Today as a Structural Wood", was a landmark publication of drawings, photographs and descriptions of early American original series was first published in and was out of print by World War II; it was revived from In Idaho, western white pine (Pinus monticola) occurs almost exclusively in the Northern Rockies about 50 years ago, it was the most abundant forest type in that region.

Prior to European settlement, the landscape pattern consisted of large mosaics of many thousands of acres, major portions of which were of a similar age class, a legacy of mixed-severity and large stand. Distribution: Western White Pine is native to southern British Columbia, western Washington, northern Idaho, western Montana, the Cascade Mountains of Oregon and the Sierras of California.

Growth: They are fast growing when young and may grow 1½-2 feet (cm) in a year. In cultivation, they sometimes reach feet (40m). The largest, growing in Oregon, near Fish Lake east of Medford, is.(2) Assuring long range economic benefits by the creation or improve- ment of stands of quality timber.

The third ABGR site (ABGR 3) consisted of relatively high biomass stands (mean = m 2 /ha) dominated by larch and western white pine in Bymean plot basal area had almost tripled to m 2 /ha due to an increase in small‐ to medium‐sized grand fir (Fig.
