Aerial Detection Monitoring
Insects and diseases are integral components of forest ecosystems. They play a critical role in shaping forest lands, nutrient recycling, and small-scale disturbance. Disturbances result in changes in the ecosystem function which often means mortality of trees. Tree mortality and other forest damage is detected by annual aerial surveys over forested lands.The primary purpose of the aerial survey is to create sketch maps of areas containing current year conifer and hardwood mortality, defoliation, and other damage. Sketch maps are captured digitally for input to the Region 5 GIS. Number of trees and acres with damage are calculated for areas surveyed and reported annually using the methodology described here.
