Title: Forest Die-Off in Southwest: 2002 and 2004
These photos show the kind of massive forest die-off that is projected to occur more frequently in the Southwest. Piñon pines, normally evergreen, have reddish-brown foliage in October 2002 (left). By May 2004 (right), the dead piñon pines have lost all their needles, exposing gray trunks and branches. The photos were taken from the same vantage point near Los Alamos, N.M. Forest drought stress is strongly correlated with tree mortality from poor growth, bark beetle outbreaks, and high-severity fire.
