Gypsy Moth Defoliation in Morris and Passaic Counties, NJ

Thu, 06/25/2015 - 14:08 -- wchristie

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.

Pandora Moth Outbreak in Kaibab National Forest, AZ

Mon, 06/22/2015 - 12:17 -- wchristie

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.

Winter Moth in ME and RI

Thu, 06/04/2015 - 08:08 -- wchristie

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.

Drought and Insect Defoliation in the Coastal Plains Post Oak Savannah of TX

Tue, 05/05/2015 - 10:03 -- wchristie

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.
