A stump of a fallen ponderosa pine tree in the Sandia Mountains, east of Albuquerque, NM. Surrounding the heartwood is the damged trunk and rotted wood caused by a pine bark beetle infestation. An intense pine bark beetle infestastion across the southwestern United States is a result from years of drought due to climactic change from global warming. A drier tree is a ripe food source for the bark beetles and more easily succombs to the infestation whereas wetter trees are hardier and repels the insects. The combination of drought and infestation weakens a tree either killis it or creates a more combustable fuel source which fuel the recent mega forest fires like Arizona's Wallow fire and New Mexico's Las Conchas fire, which were the largest forest fires in each respective state's history.
