The seeds are also an important food source for certain mammals: "Whitebark pine seeds are an important high-quality food for bear populations that occupy ecosystems with continental climates south of the United States - Canada border. 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. GBIF points are identified by their GBIF catalog number. [934] 20. We had a laser along and were able to confirm its height at 27.52 meters with a 104.4 cm DBH. Despite being over a century old, they are generally accurate, and are illustrated with some remarkable photographs and lithographs. At this time, most areas that have been hit by this infestation are still characterized by "ghost forests" consisting of the whitened snags of trees killed by the blister rust; these ghost forests are the rule rather than the exception within the range of the species. Interior Salish peoples harvested the seeds by removing the cones and roasting them overnight. In the northern Rocky Mountains of the United States, whitebark pine mortality in some areas exceeds 90 percent, where the disease infests nearly 143,000 acres (580 km2). Whitebark Pine:
Discussion. Whitebark pine (Pinus albicaulis) is a native conifer of the Western U.S. that is considered a keystone species in the sub-alpine environment. We, the U.S. ABBREVIATION: PINFLE SYNONYMS: No entry NRCS PLANT CODE [115]: PIFL2 COMM… The white snags are trees killed by white pine blister rust when it first reached this site, decades earlier. Whitebark pine, Pinus albicaulis, is a critically important tree species in subalpine and alpine western ecosystems and a candidate for listing under the Endangered Species Act. The western world values whitebark pine for its aesthetic qualities and for its value as wildlife habitat (Parish et al. Observation Search (501 records) Plant Characteristics. Distribution Mortality has been especially severe in portions of the range north of 45° latitude or west of 120° longitude (Hoff et al. A segment of about 5 minutes during Part 3, "Autumn", of the 2009 BBC documentary "Yellowstone," provides excellent footage and accurate commentary concerning the ecological role of whitebark pine vis-a-vis nutcrackers, squirrels, and grizzly bears. Seeds are dispersed mainly by Clark's nutcracker [ Nucifraga columbiana (Wilson), family Corvidae]. Bark of a tree 20 cm diameter at Sonora Pass, California [C.J. Squirrels, northern flickers, and mountain bluebirds often nest in whitebark pines, and elk and blue grouse use whitebark pine communities as summer habitat. FIGURE 1 Location of whitebark pine ( Pinus albicaulis) populations ( ) and study site (Δ near 39). Very large tree in Lamoille Canyon, Nevada [C.J. Pinus albicaulis (whitebark pine) Index. The following points may be helpful in distinguishing the three species. 1996. Whitebark pine Pinus albicaulis Engelm. USGS electronic publication. Pinus albicaulis, as described in 1863 by Georg Engelmann (1809–1884), is commonly known as whitebark pine, as well as pine à blanche écorce in the French language. Its pollen cones are scarlet.[4]. The tallest specimen ever measured was found along the Cliff Creek trail in Eagle Cap Wilderness, Oregon, on 2008.07.22 by Keala Hagmann. Engelm. Habitat: Generally near timberline, preferring south-facing slopes. Point data colors denote elevation (see pull-out menu for values). It typically occurs on cold and windy high-elevation or high-latitude sites. Seed cones borne in upper crown, remaining on tree (unless dislodged by animals), not opening naturally but through animal agency, spreading, symmetric, broadly ovoid to depressed-ovoid or nearly globose, 4-8 cm, dull gray- to black-purple, sessile to short-stalked; scales thin-based and easily broken off; apophyses much thickened, strongly cross-keeled, tip upcurved, brown; umbo terminal, short, incurved, broadly triangular, tip acute. In the absence of restoration efforts, outcomes are much worse (Keane et al. A "ghost forest" in the Olympic Mountains of Washington. [8] Scientists have attributed the recent warming trend to manmade global warming. Pinchot, Kings Canyon National Park, Sierra Nevada, California, USA. Earle, 2009.09.25]. Madrono. Pollen cones cylindro-ovoid, ca. The remaining 56 percent of the species range occurs in British Columbia and Alberta, Canada. T2 - A case study. It is of limited commercial use, but it is valued for watershed protection and esthetics. Botanical illustration including Pinus albicaulis. 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. 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. In British Columbia, it usually grows in even-aged, pure or mixed-species stands. The natural history of the stone pine/corvid mutualism is explored at length by Ron Lanner in his very engaging book Made for Each Other: A Symbiosis of Birds and Pines (1996). Evaluating future success of whitebark pine ecosystem restoration under climate change using simulation modeling. In the absence of cones, whitebark pine strongly resembles P. flexilis, and may also be confused with P. monticola. ID 63908 Symbol Key PIAL Common Name whitebark pine Family Pinaceae Category Gymnosperm Division Coniferophyta US Nativity Native to U.S. US/NA Plant Yes State Distribution CA, ID, MT, NV, OR, WA, WY Growth Habit Tree Restoration efforts undertaken by the U.S. Forest Service, Bureau of Land Management, and National Park Service in the northern Rocky Mountains involve harvesting cones from potentially and known resistant whitebark pines, growing seedlings, and outplanting seedlings in suitable sites. Location labels correspond with T able 1 . Newberry described it as "Pinus cembroides" and it was recognized and described as a distinct species by Engelmann in 1863 (Newberry 1857, Engelmann 1863). (1999). Keane, R. E., Holsinger, L. M., Mahalovich, M. F. and Tomback, D. F. 2017. The seeds were crushed to make a flour. Projected climate change at a regional level is expected to shift vegetation habitat distributions over the next century. Also see Thompson et al. A. Logan. Pinus albicaulis cones, Mt. Y1 - 2005/4/1. P Albicaulis Stock Photos and Images (14) Narrow your search: Black & white. albicaulis (Engelm.) ... Plant Distribution. Whitebark pine, whitestem, alpine whitebark, pitch, scrub or creeping pine (Peattie 1950); white pine (Little 1980); pine à blanche écorce (Kral 1993). Biomass and productivity of the subalpine Pinus albicaulis--Vaccinium scoparium association in Montana, USA. GBIF [Global Biodiversity Information Facility]. The dark green and blue-green trees are mostly Abies lasiocarpa and Tsuga mertensiana [C.J. (2017) note that recent severe decline of whitebark pine forests has happened in response to the combined effects of mountain pine beetle (Dendroctonus ponderosae) outbreaks, fire exclusion policies, and white pine blister rust. Clark's nutcrackers each cache about 30,000 to 100,000 seeds each year in small, widely scattered caches, usually under 2 to 3 cm (3⁄4 to 1 1⁄4 in) of soil or gravelly substrate. Luckman, B. H. 2006. Accurate spatial information on the distribution of whitebark pine, a keystone species in alpine environments 2n=24 (Kral 1993 and pers. 2017. U.S. Forest Service Proceedings R6-NR-FHP-2007-01. Whitebark Pine occurs in subalpine and timberline zones from west-central British Columbia east to west-central Alberta and south to central Idaho, southwestern Wyoming, and southern California (Murray, 2005; Ward et al., 2006). The fresh-cut wood of Pinus albicaulis is sweet-scented. Forest fire history in the northern Rockies. Datasheet. A 2019 assessment of all geolocated specimens shown in the range map found elevation ranging from 1159 to 3700 m, with maximum elevations roughly declining with latitude; there is also a maritime effect, with lower elevations in those parts of Washington and British Columbia where very high winter snowfall results in a relatively short growing season. Pinchot, Kings Canyon National Park, Sierra Nevada, California, USA. Species distribution. A suspected hybrid between Pinus albicaulis Engelm. [6] Whitebark deaths in North Cascades National Park doubled from 2006 to 2011. Diameter 268 cm, height 21.0 m, crown spread 14 m, in Sawtooth National Recreation Area, Idaho (American Forests 1996). Absent the effects of climate change, it would be reasonable to suppose that P. albicaulis would gradually develop a tolerance for the blister rust, as is seen in white pines of the Old World, most of which show some susceptibility to the disease but are not severely affected by it.
