Pandora Moth Outbreak in Kaibab National Forest, AZ

ForWarn identified an anomaly in the Kaibab National Forest of Arizona near the Jacob's Lake area. Defoliation is actively growing and shifting between hosts, timing, and species. This is because of a reduction in vulnerable host species, parasites and pathogens that decline populations of defoliator species, and subtle differences in environmental conditions across years and places. It is probably that the pandora moth is the cause of the decline in the area by defoliating ponderosa pines.
