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.
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.
