ForWarn identified a defoliation disturbance in Louisiana's Atchafalaya River Basin coastal swamp forest. The defoliation in the area of concern is often an annual occurrence. Based on past data, the defoliation is the work of the forest tent caterpillar and bald cypress leaf roller.
ForWarn detected an apparent decline in vegetation greenness near Jackson Lake, Wyoming. The moderate and persisting decline does not exhibit the behavior of a fire. Mountain pine beetle has been common in years prior in areas nearby the anomaly and is likely the defoliator in this instance.
ForWarn identified anomalies along the Olympic Peninsula of Washington. The event is attributed to insect defoliation.
ForWarn detected a progressing decline along the Wind River Range in Wyoming. The mountain range, part of the Rocky Mountains, has been declining incrementally over the three most current dates. Insect defoliation is the likely cause for this event.
ForWarn observed a drop in vegetation greenness in the Teton Wilderness, Wyoming. Although there was a burn in 2012, this event is probably insect defoliation.
ForWarn detected a multiple threat anomaly in the Adirondacks, New York. The progressive decline in the mountain range could be due to insect defoliation or the summer phenology of the plants.
ForWarn identified a persistent reduction along the ridges of central and east Pennsylvania. The areas of concern have a history of insect defoliation during the spring and summer. Although there is evidence of hail damage in nearby counties, the anomaly along the ridges is likely due to insect defoliation.
ForWarn detected a disturbance in southern Florida in May 2014. Laurel Wilt fungal disease is terminal in plants of the Laurel family. Drought induced dieback of vegetation as well as insect defoliation may also play a part in greenness departure. This event was revisited in July 2014 with newer imagery but the cause is still undetermined.
ForWarn detected a disturbance in the New Jersey Pine Barrens. The heavily forested area extends through seven New Jersey counties. Insects are suspected to be defoliating the area accounting for the departure of vegetation greenness.
ForWarn discovered an anomaly in Berks and Chester counties of Pennsylvania. Insects are suspected of defoliation, promoting greenness departure.
