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...

Emerald Ash Borer damage areas by damage type are displayed within the insect and disease survey areas. The 2011 insect and disease survey is displayed by default. A map service on the www depicting a compilation of forest insect, disease and abiotic damage mapped on forested areas in the United States that provides a single, consistent data source to facilitate national and multi-regional reporting for Forest Health Monitoring and Forest Health Protection. All reported emerald ash borer damage types are shown within the insect and disease survey areas from 2007 to 2011.

2009 USDA Forest Service, Rocky Mountain Region Aerial Detection Survey Data. "Flown/ not flown" (r209_flown) feature class. This data depicts the spatial extent where the 2009 aerial detection survey took place. This data set is a companion to the r209_dmg data, which depicts the occurrence and location of 2009 forest insect, disease, and other biotic and abiotic causes of tree mortality and tree damage. The r209_flown data set provides information on which areas were surveyed, when the areas were surveyed, who the surveyors were (and their respective agencies), and what type of survey took place. Air turbulence, cloud shadows, distance from aircraft, haze, smoke, etc., which affect survey accuracies, may also...
