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.
ForWarn identified anomalies in the Lyon and Johnson Mountains, New York. There are several possible causes for this event. Clouds may obstruct the detector providing a false anomaly, insects may be defoliating the area, the phenology of the plants could play a part in departure, or sever weather causing damage to foliage.
ForWarn detected an anomaly in the Allegheny National Forest, Pennsylvania in August 2012. Insect defoliation is the probable cause for the decline in vegetation greenness.
ForWarn detected a disturbance in Potter County, Pennsylvania in July 2012. The cause for the decline in vegetation greenness is currently unknown but may be attributed to insect defoliation.
