Whitebark pine (Pinus albicaulis) is a keystone species (Tomback et al. 2001), forming subalpine and treeline forests that supply food and shelter for hundreds of plant and animal species. This trait makes whitebark pine a “quintessential” high elevation conifer and it forms unique habitat types with both geographic and successional variation that support considerable biodiversity across the higher mountains of the United states and Canada. (Tomback et al. 2001, Tomback and Achuff 2010). Whitebark
