For each damage agent, a composite index was created by analyzing the ADS data for the past 5 years (2005 - 2010) collectively to identify those epicenters of high mortality and adjacent areas to determine the potential for future mortality. The areas adjacent to existing mortality where futuremortality has a greater chance of occurring.To achieve this, a simple crosswalk was completed.Number of Years of Mortality Current Forest Mortality IndexFuture Risk of Mortality (Next 5 Years)0Non-Infested Low1-2Low to Low-Moderate Moderate3-4`Moderate to Moderate-High High>5HighVery High These data are provided by Bureau of Land Management (BLM) "as is" and may contain errors or omissions.

2010 USDA Forest Service, Rocky Mountain Region Aerial Detection Survey Data. This data depicts the occurrence and location of forest insect, disease, and other biotic and abiotic causes of tree mortality and tree damage. Aerial survey data is collected by observing areas of tree damage or tree mortality from an aircraft and manually recording the information onto a map. Due to the nature of aerial surveys, this data will only provide rough estimates of location, intensity and the resulting trend information for agents detectable from the air. Many of the most destructive diseases are not represented in the data because these agents are not detectable from aerial surveys. The data presented should only be used as...
