USGS Distribution Map

Whitebark Pine (Pinus albicaulis)

Needles: Bundles of 5, 1-3" long

Cones: 2-3" long, thick-scaled

Bark: Light gray, scaly

Where: Above 5000 ft.

  

Needles: Whitebark pine has 5 needles per bundle, like Western White pine, but with few other similarities. 

Cones: Its cones are only 2 to 3 inches long. They are purple, turning brown as they mature. The cones are often pulled apart by birds to get the seeds so only cone fragments are found on the ground.

Bark: The bark is light gray, and the twigs are flexible like rope.

Where it grows: Whitebark pine grows near the timberline in the Cascades, often along windy ridges, where it is small and contorted. Elsewhere in Oregon, it grows in the mountains near Baker City. It also grows throughout the Rocky Mountains.

Similar tree: Limber Pine is a similar 5-needle pine, common in the Rocky Mountains. It also grows in the Wallowa Mountains of Oregon.

Uses: Whitebark Pine produces the largest seeds of all the conifers of Northwest Oregon. These seeds, often called "pine nuts," are edible. They are a vital food source for Clark's Nutcrackers, which in turn are vital to seed dispersal for Whitebark Pine. Nutcrackers cache the seeds in the ground, and some of the seeds sprout there. The two are so dependant on one another, if you see one of them the other is likely to be close by.

Names: The common and scientific names describe the Whitebark Pine. Albicaulis means "white stemmed." To remember the name, think of it as the "Albino-bark Pine." Other common names: pitch pine, scrub pine, and creeping pine. John Muir called it "Dwarf Pine."
