ForWarn discovered an unknown decline in vegetation greenness. Identified in July, 2015, northeast Georgia experienced a decrease anomaly of unknown sources. Clouds potentially obstructed the analysis abilities of the detector.
ForWarn detected multiple possible defoliation events in the Humboldt National Forest, Nevada in July 2015. The pine dominated forest could be affected by insect defoliation and/or severe drought die back. Pinyon pine defoliation is common in this area during this time of year in the warmer, lower elevations. However, higher elevations were also being affected by departure of vegetation greenness. There is still speculation on causality of decline but most likely affected by insect outbreak defoliation and drought induced die back of vegetation.
ForWarn detected multiple possible defoliation events south of White Pine County, Nevada in July 2015. The pine dominated forest could be affected by insect defoliation and/or severe drought die back. Pinyon pine defoliation is common in this area during this time of year in the warmer, lower elevations. However, higher elevations were also being affected by departure of vegetation greenness. There is still speculation on causality of decline but most likely affected by pinyon pine scale insect outbreak defoliation and drought induced die back of vegetation.

ForWarn identified small disturbances in the San Juan National Forest, Colorado. The anomalies were disturbed west of the Weminuche Wilderness near Graham and Granite peaks and Slide Mountain. Because the area consists of mainly spruce-fir forests, the spruce beetle is a potential defoliator causing the departure of vegetation greenness. Confirmed causes are still unkown.
ForWarn detected an anomaly in the San Isabel National Forest, CO. Affecting mostly lodgepole pine forests as well as some spruce-fir forest, the reason for the decline is currently unknown.
ForWarn identified an anomaly in eastern Colorado and New Mexico border. There was a decline in ponderosa pine greenness compared to the one year change data. Causes for the anomaly are currently unknown.
ForWarn detected a small disturbance south of Carson National Forest, New Mexico. The anomaly was short-lived in July 2015 and the cause of the anomaly is currently unknown.
ForWarn detected a disturbance in the Rio Grande National Forest of southern Colorado in July 2015. The spruce-fir zone of the forest was the most affected; the vegetation greenness departure cause is unknown with a possibility of insect outbreak.
ForWarn discovered two anomalies in the Fremont National Forest, Oregon. The two anomalies are seemingly related, one being larger in extent. The anomaly appears to be slightly brown with highly green forest adjacent. The reason for the large decline within the forest is currently unknown.
