This map, produced by Wally MacFarlane, Dr. Jesse Logan, Willie Kern, and GEO/Graphics, Inc., shows many areas of widespread mountain pine beetle-caused whitebark pine mortality. The heaviest hit areas are likely threatening the ability of this important species to provide key ecological services to the ecosystem.

Thank you for the excellent presentation last night.
You’re welcome. The Earth Day presentation was just the start of our Fight to understand and hopefully save the Yellowstone Whitebark!
Stay tuned. Get involved, donate and start a fight!
That is a very powerful map. It must have taken an incredible amount of work to assess all that forest and accurately present it. Thank you for making the effort to inform the rest of us.
