whitebark
High-mountain pine species
Whitebark typically describes trees characterized by pale or white bark.
The whitebark pine is a high-elevation conifer of western North America, valued for its seeds that feed wildlife including grizzly bears and Clark's nutcrackers.
Whitebark pine populations have declined dramatically due to blister rust and beetle infestations.
