Description from Wikipedia

Pinus albicaulis, with many common names including whitebark pine, white pine, pitch pine, scrub pine, and creeping pine, occurs in the mountains of the Western United States and Canada, specifically the subalpine areas of the Sierra Nevada, the Cascade Range, the Pacific Coast Ranges, and the Rocky Mountains from Wyoming through the Continental Ranges. It shares the common name creeping pine with several other "creeping pine" plants.

Conservation Summary

  • Globally
    vulnerable (G3G4) (Source: NatureServe)
    Vulnerable. A common tree where it occurs, it is limited to only upper subalpine forests of many western North American mountain ranges. It is, however, severly threatened in the majority of its range by introduced white pine blister rust (<i>Cronartium ribicola)</i>, outbreaks of mountain pine beetle (<i>Dendroctonus ponderosae</i>), succession resulting from decades of fire suppression, climate change resulting in decreases in suitable habitat, and various synergies between these factors. Although a few areas such as the southern Sierra Nevada in California and the interior Great Basin ranges, as well as scattered stands in the rest of the range, still appear to contain large numbers of relatively healthy trees, it is expected that the blister rust will eventually become abundant in the vast majority of the range, causing significant tree mortality. Tree mortality rates exceeding 50% have already been documented in numerous parts of the range. A small percentage (1-5%) of trees appear naturally resistant to the blister rust, and restoration strategies hope to propagate these genotypes for use in restoration, although even rust-resistant trees will remain threatened by other factors. In addition, it has relatively low genetic variation and exists as a fragmentary species, making it more vulnerable than its range might indicate. This is a keystone species of high-elevation western ecosystems whose decline is expected to have cascading effects on ecosystem function and biodiversity.
