A lodgepole pine stand in the Bridger-Teton National Forest, WY in 2007. This lodgepole stand, while it could be classified as being in the red stage, also has quite a few trees that are still green (unattacked) and others that have already lost their needles; that is because tree mortality occurs over several years—in this case, the trees were attacked continuously over a three year span.
