Southwest U.S. Change Detection Images: Reno and Lake Tahoe, Nevada

CONIFER MORTALITY AREA

This area has been studied by scientists at Boston University. They have ground measurements to quantify the decrease in the forestcanopy as a result of the drought. The sustained drought conditions weakenedthe trees and made them more susceptible to insect attacks.The areas of orange on the edge of the lake outline a confirmed area of tree kill.
