| Summary: | Forest damage caused by a variety of agents: wildfire, climatic events, mammals, insects and diseases is often highly visible and can be assessed by remote sensing. Certain characteristics of the damage, as seen via remote sensing, can provide clues to the identity of the agent(s) responsible for the damage. These include the ability to recognize the host tree(s) affected, color and texture of the foliage of affected trees, distribution of damage, size of affected trees and portion of tree crown affected. Examples are provided from the United States and southern Brazil of how combinations of these characteristics are helpful in the identification of damaging forest agents during aerial sketchmap surveys, interpretation of large to medium scale aerial photos or airborne video imagery. |
