For each damage agent, a composite index was created by analyzing the ADS data for the past 5 years collectively. The assumption is that the longer the infestation has been in one location, the higher the mortality. This can then be used to identify those epicenters of high mortality and adjacent areas to determine the potential for future mortality.
