In each of these forests, the giant trees and open understory were a legacy of frequent, low-intensity fire that excluded competitors, discouraged root rot fungi, and maintained an optimum growing environment for the dominant canopy tree species. The analysis by Potter et al. This series of volumes, privately printed, provides some of the most engaging descriptions of conifers ever published. The pitch or sap was used by many tribes including the Cheyenne, Flathead, Okanogan, Colville, Paiute, and Thompson for a wide variety of purposes including as a salve or ointment for sores, boils, cuts and earache; to reduce inflammation of the eyes; to treat backache or rheumatism; and to pacify babies by spreading it on their skin. Means. 1900 [J. W. Cowden] (courtesy Gary Dielman, Baker City library). Philosophical Transactions of the Royal Society of London. Ponderosa pine. My observations are dated, precisely located, and include a listing of associated tree species ranked in descending order of dominance. Mahalovich, and R.E. Wood Magazine. benthamiana has slightly larger cones, with a recurved prickle, while subsp. Mountain Press Publishing Company, 119 pages. Earle, 2002.05.25]. Ponderosa Pine Range. (2013) cite paleoecological evidence of P. ponderosa occurrence in the southern Sierra Nevada during the last glacial maximum as the closest known presence of the species at that time. Although his efforts to find solar cycles in tree rings were largely unsuccessful, his techniques also served to develop the use of tree-ring methods to date wood used by prehistoric peoples throughout the American southwest, and this very successful dating technique led to the proliferation of dendrochronology as a science. scopulorum (Engelmann) E. Murray is the most widespread of the interior subspecies. Earle, 2017.09.21]. lowiana, but the open character and giant trees are highly reminiscent of pioneer accounts of Pinus ponderosa forests of the West. Mature tree growing on the rim at Bryce Canyon National Park, Utah [C.J. The wood was widely used in structures, to make dugout canoes, and for other uses such as cradle boards, ladders, and of course firewood (University of Michigan Ethnobotany Database 2013.09.07). Trees to 18-39(-72) m tall with 80-120(-250) cm diameter, straight; crown broadly conic to rounded. In Status and Trends of the Nation's Biological Resources. There is still substantial uncertainty about what is going on west of the Cascade Crest in Washington and Oregon. 2018. Near the southern range limits of the subspecies, however, the picture becomes more complex. ponderosa has smaller cones, with an incurved prickle. The Fort Lewis sample had the typical variety haplotype and the Eugene sample had the benthamiana haplotype. Click or tap to ask a general question about COVID-19. The discussion below refers a rather complex range map, formerly shown on this site, but now you have to download this KML file and open it in Google Earth, due to severe limitations in the display capabilities of the latest Google map interface (which supports only a minor subset of KML). But to me there is something more impressive in the fall of light upon these silver pines. All ponderosas have vanilla-scented inner bark [C.J. The Nez Perce indians used to harvest the inner bark to feed their horses in early spring when better forage was still buried deeply beneath the snows. This one grows in a cold open meadow at high elevation in the eastern Cascades [C.J. Five different mitochondrial haplotypes help to differentiate subspecies scopulorum (analysis by Potter et al. See also Thompson et al. Analysis by Potter et al. Since that time, the taxonomy of the ponderosa complex has been the subject of continuing dispute. Earle, 2015.11.20]. In the historical period, an enthusiastic program of fire suppression has virtually eliminated these small, frequent fires. 2018. It is present in early, mid-, and late stages of secondary succession; it is a variable component in old-growth stands in the IDF zone and the only component in the PP zone. This is the most commercially important western pine (Little 1980). *Don't provide personal information . 2009. Ponderosa has been the subject of hundreds of studies, and indeed the invention of the science of dendrochronology by astronomer Andrew Ellicott Douglass began with his inspection of ponderosa pine stumps near Flagstaff, Arizona. http://biology.usgs.gov/s+t/SNT/noframe/sw153.htm, accessed 2002.09.03. Needles 2-5 per fascicle, spreading to erect, persisting (2)4-6(7) years, 7-25(30) cm × (1)1.2-2 m… The complete map includes: Distribution data; see text above for explanation. 2013), which is predominant in populations in the Puget Trough, the Willamette Valley, and the Klamath-Siskiyou region. The cause of this disjunct pattern is not known, but may represent a consequence of northward dispersal from a former Mexican refugium during climatic warming and drying since the last glacial maximum. Seeds ellipsoid-obovoid; body (3)4-9 mm, brown to yellow-brown, often mottled darker; wing 15-25 mm (Little 1980, Kral 1993). Younger trees have blackish-brown bark, referred to as "blackjacks" by early loggers. Branches descending to spreading-ascending; twigs stout (to 2 cm thick), orange-brown, aging darker orange-brown, rough. Now, when a fire does occur, it is likely to be extremely destructive, destroying vast stands of prime forest.

Buds ovoid, to 2 cm, 1 cm broad, red-brown, very resinous; scale margins white-fringed. A variant haplotype found south of San Francisco Bay (shown in gray) is differentiated by a single mutation from the green haplotype. Needles 2-5 per fascicle, spreading to erect, persisting (2)4-6(7) years, 7-25(30) cm × (1)1.2-2 mm, slightly twisted, tufted at twig tips, pliant, deep yellow-green, all surfaces with evident stomatal lines, margins serrulate, apex abruptly to narrowly acute or acuminate; sheath 1.5-3 cm, base persistent. Even today its management is the first concern of forest management across most of the West, and endless studies have been published on the species' fire ecology, its response to climate change, its vulnerability to diseases, the ecological functions of every life history stage from seedlings to old growth, and countless other attributes of the species' biology. That forest was logged long ago. Agriculturist's Manual. It is still possible to see such a forest, but to do so you must go to Mexico, specifically to the Sierra San Pedro Martír in Baja California. Pinus ponderosa and P. flexilis growing over a ground cover of manzanita (Arctostaphylos sp.) 2013), as well as earlier primarily morphological analyses by Lauria (1991, 1996a, 1996b). P. ponderosa subsp. Lawson, P. 1836. - John Muir, The Mountains of California. Color coding is the same as used in their paper. Found in every western state from Nebraska to the Pacific, one can seldom travel far in the West without seeing a ponderosa (or, it is often called, "yellow pine"). Nearly everyone ate the seeds, usually roasted, sometimes ground into a flour. ); rabbits, hares, pocket gophers, Associated tree species and successional role. 2004, cited by Potter et al. Earle, 1998.04.17]. The two haplotypes are very closely related. Branches descending to spreading-ascending; twigs stout (to 2 cm thick), orange-brown, aging darker orange-brown, rough. Lascoux, M., A.E. It may be that the cyan and purple haplotypes represent separate processes of radiation from a Pleistocene refugium located in a southern locale; Potter et al. Three haplotypes were only observed in 5 populations; for those, the third is not shown here. Ponderosa pine is a species of lean and erect coniferous trees distributed in the western US and Canada. Ovulate cones maturing in 2 years, shedding seeds soon thereafter, leaving rosettes of scales on branchlets, solitary or rarely in pairs, spreading to reflexed, symmetric to slightly asymmetric, conic-ovoid before opening, broadly ovoid when open, 5-15 cm, mostly reddish brown, sessile to nearly sessile, scales in steep spirals (as compared to Pinus jeffreyi) of 5-7 per row as viewed from side, those of cones just prior to and after cone fall spreading and reflexed, thus well separate from adjacent scales; apophyses dull to lustrous, thickened and variously raised and transversely keeled; umbo central, usually pyramidal to truncated, rarely depressed, merely acute, or with a very short apiculus, or with a stout-based spur or prickle.
