ForWarn identified a decline in vegetation greenness in the Rio Grande National Forest and southern San Juan Wilderness. It is a possibility that the severe tree mortality is due to snow impacts or intensification of apparent spruce beetle defoliation.
ForWarn identified a decline anomaly in the Morris and Passaic Counties of New Jersey. Gypsy moth is historically active in the area during the time of reporting, June 2015. Defoliation in the area of concern is consistent with defoliation of the previous year. Based on past data, decline in vegetation greenness could potentially intensify.
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.
ForWarn observed a decline in the swamp forest of Louisiana. The decline has occurred annually due to insect defoliation.
ForWarn discovered defoliation in the Pennsylvania ridges and New Jersey highlands. The area of the anomaly is consistent with anomalies of years prior. This consistent behavior is apparent for insect infestations likely including the gypsy moth, among others.
ForWarn identified an increasing anomaly along the coastal border of Rhode Island and Maine. The intensification is consistent with previous year's data to be apparent winter moth defoliation. Residual tornado damage to vegetation greenness may also attribute to the anomaly.
ForWarn identified a disturbance in the bottomlands of coastal South and North Carolina. The swamps of the Carolinas have seen progressive defoliation by an unknown insect.
ForWarn displayed a disturbance in the Trinity River swamps in southeast Texas. The moderate decline in vegetation greenness is potentially due to insect defoliation within the swamps.
ForWarn displayed a disturbance in the Atchafalaya and Lake Maurepas swamps of southeastern Louisiana. The prominent defoliation is likely due to an insect of unknown species.
ForWarn discovered a disturbance in East Central Texas within the coastal plains post oak savannah. Detected mostly in hardwood areas, the decline may be attributed to the 2001 drought. Based on previous data, the area of concern has had periodic decline and wilt issues. The large scale decline is associated with loss of eastern red cedar from delayed drought mortality as well as cankerworm defoliation.
