The big picture on whitebark pine

FS News Posted on: August 31, 2018
Throughout the western United States, whitebark pine is experiencing high mortality, leading to concern about long-term viability of whitebark pine and other species that depend on it. Two new studies of whitebark pine in the western U.S. show that this species continues to die-off in alarming numbers and identifies locations where forest managers may be able to encourage growth of young whitebark pines.

Landscape-scale assessments of whitebark pine

Science Spotlights Posted on: August 23, 2018
Forest inventory data show that more than half of all standing whitebark pine trees in the U.S. are dead. Regeneration of whitebark pine is widespread, especially in lodgepole pine stands, which suggests that active management of whitebark pine should target mixed-species stands to take advantage of natural regeneration.

Whitebark pine distribution and regeneration

Media Gallery Posted on: June 04, 2018
Whitebark pine (Pinus albicaulis) is an ecologically important species in high-altitude areas of the West due to the habitat and food source it provides for Clark’s nutcrackers, red squirrels, grizzly bears, and other animals. Whitebark pine stands have recently experienced high mortality due to wildfire, white pine blister rust, and a mountain pine beetle outbreak, leading to questions about the species’ long-term viability. This project seeks to quantify the current distribution and regeneration status of whitebark pine throughout its US range.
