Whitebark Pine Research & Recovery

Whitebark pine trees along the Avalanche Peak trail.When hiking through the high elevations of the park, you may hear the distinct raspy calls of the Clark’s Nutcracker. For the hardy Whitebark pine, this bird is more than a noisy member of the forest. It is a key component to the pine’s survival. Whitebark pine (Pinus albicaulis) is a slow-growing, rugged tree that thrives in high-elevation mountain regions of North America.

One of its most notable mutualistic relationships is with Clark’s Nutcracker, a bird that relies on Whitebark pine seeds for sustenance. In turn, the bird helps disperse these seeds, ensuring the tree’s propagation. However, Whitebark pines are currently facing severe threats from a changing climate, pine beetle infestations, and white pine blister rust. Conservation efforts are crucial to protect and restore these trees, which are integral to the health and biodiversity of the park.

This project relies on YF funding to gain park-level data and knowledge of whitebark pine health so park managers can strategically identify areas of highest risk and probability of successful recovery of this keystone species.
