Unknown Disturbance in Humboldt National Forest, NV

ForWarn detected multiple possible defoliation events in the Humboldt National Forest, Nevada in July 2015. The pine dominated forest could be affected by insect defoliation and/or severe drought die back. Pinyon pine defoliation is common in this area during this time of year in the warmer, lower elevations. However, higher elevations were also being affected by departure of vegetation greenness. There is still speculation on causality of decline but most likely affected by insect outbreak defoliation and drought induced die back of vegetation.
