Limber Pine

About Limber Pine in Alberta

Limber Pine is a native and endangered Alberta five-needle pine of the southwestern Rockies and adjacent foothills, especially on dry rocky ridges, open slopes, and other exposed mountain-edge sites. For Ancient Roots Alberta, its importance lies in the combination of rarity, great longevity, harsh-site persistence, and declining conservation status: a healthy old cone-bearing Limber Pine can represent both deep landscape continuity and active species-at-risk value.

Identification: Needles occur in bundles of five and are one of the easiest field marks. They are usually about 3-7 cm long, bluish-green to dark green, and notably pliant, bending without snapping easily. This flexibility is one of the simplest ways to understand the tree's common name.

Alberta range and habitat: In Alberta, Limber Pine is restricted to the southwest, from near Kootenay Plains south to the United States border. It is naturally scattered through the Rocky Mountains and adjacent foothills rather than broadly distributed across the province.
