In more favorable conditions, the trees may grow to 29 meters (95 ft) in height. The wood of the western white pine is easily worked with carpenter’s tools, and is ideally suited for applications including window and door frames, paneling, shelving, and some structural applications. The scales often have a white, sticky resin on them. needles per bundle. Western White Pine. it grows: Western white pine grows Squirrels, northern flickers, and mountain bluebirds often nest in whitebark pines, and elk and blue grouse use whitebark pine communities as summer habitat. In Pinus flexilis, the cones are 6–12 centimeters (2 1⁄2–4 1⁄2 in) long, green when immature, and open to release the seeds; the scales are not fragile. As such, it is the first federally listed endangered tree in western Canada. In Pinus albicaulis, the seed-bearing female cones are 4–7 centimeters (1 1⁄2–3 in) long, dark purple when immature, and do not open on drying, but the scales easily break when they are removed by the Clark's nutcracker to harvest the seeds; rarely are there intact old cones in the litter beneath the trees. [1] Severe population decline in whitebark pine communities is attributed to various causes, most significantly infection with white pine blister rust, recent outbreaks of mountain pine beetles (2000–2014), disturbances in wildland fire ecology (including fire suppression), forest succession, and climate change. Uses: Western white pine is a medium- to large-sized (exceptionally >70 m tall) evergreen conifer. Trees 30(70) m tall and 100(250) cm in diameter, straight; crown narrowly conic, becoming broad and flattened.

In response to the ongoing decline of the tree throughout its range, the Whitebark Pine Ecosystem Foundation was formed. Western White Pine (Pinus Monticola) Besides the yellow and sugar pine that have already been noted there will be found among the firs and hemlocks, well up in the park, another handsome pine, with a clear, round trunk and reddish-brown bark, broken up into small square blocks. It can grow to 200 feet (60 meters). [6], Many stands of Pinus albicaulis across the species' entire natural range are infected with white pine blister rust (Cronartium ribicola), a fungal disease introduced from Europe. About one-third of the annual production goes to cut-up plants for remanufacture. However, the beetles have recently expanded their attacks to younger, healthier trees as well as older trees, and climate change has been implicated as the primary culprit. Their mission is to raise awareness and promote conservation by sponsoring restoration projects, publishing a newsletter called "Nutcracker Notes", and hosting an annual science and management workshop for anyone interested in whitebark pine. whole bark ground in a Wiley mill to 1126 pass a 2-mm mesh screen was CfiH,,-extracted in a Soxhlet as previously described [1]. Western white pine has 5 The blister rust has also devastated the commercially valuable western white pine in these areas and made serious inroads in limber pine (Pinus flexilis) populations as well. Western White Pine Cone. Western white pine (Pinus monticola) also called silver pine, and California mountain pine, in the family Pinaceae, is a species of pine that occurs in the mountains of the western United States and Canada, specifically the Sierra Nevada, the Cascade Range, the Coast Range, and the northern Rocky Mountains.The tree extends down to sea level in many areas, particularly in Oregon and Washington. Idaho. Some com mon grade lumber is used in the fabri - cation of laminated roof decking. Western white pine grows rapidly to a large size; one of the largest standing trees measures 200 cm (78.6 in) in d.b.h. Pinus monticola Douglas ex D. Don – western white pine Subordinate Taxa.

Whitebark pine (Pinus albicaulis) can also be hard to distinguish from the western white pine (Pinus monticola) in the absence of cones. Consequently, whitebark pine often grows in clumps of several trees, originating from a single cache of two to 15 or more seeds. Entire forest vistas, like that at Avalanche Ridge near Yellowstone National Park’s east gate, have become expanses of dead gray whitebarks. [6] The pine beetle upsurge has killed nearly 750,000 whitebark pines in the Greater Yellowstone Ecosystem alone. [13] This U.S. group collaborates closely with the Whitebark Pine Ecosystem Foundation of Canada. ], Fire suppression has led to slow population declines over the last century by altering the health and composition dynamics of stands without the fire ecology balancing their habitat and suppressing insect-disease threats. Whitebark pine also has 5 needles per bundle, but usually grows at higher elevations near the timberline. Abstract Eleven new triterpenes with the lanostene‐type skeleton were isolated from the benzene extract of western white pine bark. Other animals also depend upon the whitebark pine. matches. [7] The beetles both lay their eggs and introduce pathogenic fungi into their host trees, which include many other species of pine, and the combination of larval feeding and fungal colonization is typically sufficient to kill old or unhealthy trees. Sixteen-year-old western white pine growing under an overwood density of 6 m²/ha (27 ft²/acre) were 2.0 m (6.6 ft) tall compared to trees 0.5 m (1.6 ft) tall growing under an overwood density of 21 m²/ha (91 ft²/acre) (28). [6][9], In 2007, the U.S. Pinus albicaulis, known by the common names whitebark pine, white bark 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. Buds ellipsoid or cylindric, rust-colored, 0.4-0.5cm, slightly resinous. Description Western White Pine is a Northwest native best known for its thin needled foliage which appears fine and feathery with a light blue-green color. Unusually large outbreaks of mountain pine beetle (Dendroctonus ponderosae), a species of bark beetle native to western North America, have also contributed significantly to the widespread destruction of whitebark pine stands. Distinguishing whitebark pine (Pinus albicaulis), from the related limber pine (Pinus flexilis), also a member of the white pine group, is much more difficult, and usually requires seed or pollen cones. Western white pine was first described and named by David Douglas. In northwest Oregon and western Washington, you can Here are a few tips on how to do it. Although not a The color of the bark is reddish-brown and grayish-brown, but also can be pinkish if younger. Grizzly bears and American black bears often raid squirrel middens for whitebark pine seeds, an important pre-hibernation food. identify it by Bark: Reddish-brown and furrowed; broken into long plates on older trees (narrow plates on young trees). Its lightweight, nonresinous, straight-grained wood exhibits dimensional stability that makes it particularly valuable for sash, frames, and doors, interior paneling, building construction, match wood, and toothpicks. The whitebark pine is typically the highest-elevation pine tree found in these mountain ranges and often marks the tree line. Stone pines are distinguished by large, dense seeds that lack wings and therefore depend upon birds and squirrels for … Whitebark pine needles are also usually shorter, 4–7 centimeters (1 1⁄2–3 in) long, though still overlapping in size with the larger 5–10 centimeters (2–4 in) needles of the western white pine. and 72.8 m (239 ft) tall in the mountains near Medford, OR. Plywood, too, is made from western white pine. Western white pines (Pinus monticola) grow from 8,000 feet to just below timberline.They look much like sugar pines, but are distinguished by their checkerboard bark and smaller cones. Western white pine growth can be inhibited even by the shade of a light shelterwood. Needles: In California, where the blister rust is far less severe, whitebark pine is still fairly common in the High Sierras. The bark Whitebark pine (Pinus albicaulis) is a member of the white pine group, the Pinus subgenus Strobus, and the section Strobus; like all members of this group, the leaves (needles) are in fascicles (bundles) of five with a deciduous sheath. Quick Information. feet (900 to 1500 meters) in Oregon and down to sea level in northwest grows in northeast corners of Oregon and Washington, and in northern The whitebark pine is an important source of food for many granivorous birds and small mammals, including most importantly the Clark's nutcracker (Nucifraga columbiana), the major seed disperser of the pine. Think of them as more like fissures rather than ridges. Needles 5 per fascicle, spreading to asce… Western White Pine. Though the tree is not entirely “white,” the bark does start out light grey when young and matures to a darker brown color with deep rivets and thick texture. Nearly 80 percent of whitebark pines in Mount Rainier National Park are infected with blister rust.[6]. Whitebark pine is most often seen near the timberline, where its growth is attenuated by the harsh conditions there. A study in the mid-2000s showed that whitebark pine had declined by 41 percent in the western Cascades due to two primary threats: blister rust and pine beetles. The length is banana sized, too. In cultivation, they sometimes reach 135 feet (40m). The extract consisted of 13% phlobaphenes, 18% strong acids, 21% polar weak acids, 6.5% fatty acids, 9.5% resin acids, and 32% neutrals. Thus, it is often found as krummholz, trees growing close to the ground that have been dwarfed by exposure. throughout the Cascades and in the Coast Range at elevations of 3000 to In California, it grows in the Issaquah, Washington State, USA.

Since 2000, the climate at high elevations has warmed enough for the beetles to reproduce within whitebark pine, often completing their life cycle within one year and enabling their populations to grow exponentially. [14], Native Americans are known to eat the seeds from the cones of this tree. Those caches not retrieved by the time the snow melts contribute to forest regeneration. Eastern White Pines (Pinus strobus) are a good source of wild food. The bark of the mature western white pine is brownish-gray, and is broken into small rectangular blocks. Pine trees can be identified by their needle-like leaves, seed-bearing cones, and reddish-brown or gray bark.Another identifying feature of pine trees is their egg-shaped cones that hang down from branches.
