The Whitebark and Limber Pine Information System provides distributional information at the stand level.
It was a minor component of subalpine forests in British Columbia and Alberta, and showed scattered occurrence on the Olympic Peninsula, the southern Cascades and other ranges of southern Oregon and upper northern California, and in northern Nevada .
At high elevations, krummholz whitebark pine communities merge into alpine vegetation. Department of Agriculture, Forest Service, Intermountain Research Station: 179-187.
At mid-elevation, whitebark pine communities merge into mixed-conifer forests [17,30].
Several other conifer species may share dominance with whitebark pine.
Such entities are rare and apparently infertile [51,59]. Its distribution splits into 2 broad sections, 1 following the Coast and Cascade ranges and the Sierra Nevada, and the other following the northern Rocky Mountains. Whitebark pine communities: Ecology and restoration.
Department of Agriculture, Forest Service, Rocky Mountain Research Station, Fire Sciences Laboratory (Producer). The scientific name of whitebark pine is Pinus albicaulis Engelm. Whitebark pine is the only stone pine (subgenus Strobus, section Strobus, subsection Cembrae) native to North America [53,118]. flexilis) have been crossed in the laboratory, and putative hybrids between the 2 species have been identified on the Rocky Mountain Front of Montana. In: Tomback, Diana F.; Arno, Stephen F.; Keane, Robert E., eds.
Whitebark pine was a major component of subalpine forests in the northern Rocky Mountains, the northern Cascades, the Blue Mountains, and the Sierra Nevada. In: Schmidt, Wyman C.; Mc Donald, Kathy J., compilers.
It comprises 10 to 15% of total forest cover in the northern Rocky Mountains. Proceedings--symposium on whitebark pine ecosystems: ecology and management of a high-mountain resource; 1989 March 29-31; Bozeman, MT.
At mid-elevation, whitebark pine throughout its range is associated with lodgepole pine (Pinus contorta) [75,87,126,185,230].
