Whitebark Pine

About Whitebark Pine in Alberta

Whitebark Pine is a native and endangered Alberta five-needle pine of upper subalpine and treeline mountain environments, where it persists on exposed ridges, rocky slopes, avalanche openings, and other severe high-elevation terrain. For Ancient Roots Alberta, it is important not just because it is uncommon, but because it is a long-lived keystone tree whose survival affects wildlife food webs, slope stability, and mountain watershed function across Alberta's western ranges.

Identification: Needles occur in bundles of five and are relatively short, stiff, and slightly curved, usually around 3-7 cm long. They often create dense tufted clusters near branch tips and tend to look shorter and less flexible than Limber Pine needles.

Alberta range and habitat: Whitebark Pine is restricted to Alberta's western mountains, occurring from the Jasper region south through Banff, Waterton, and associated Rocky Mountain landscapes. It is not a foothill generalist and not a lowland Alberta species.
