High-Altitude Photography for Inventories of Mountain Pine Beetle Damage
High-altitude panoramic color infrared photography was used to assess a mountain pine beetle (Dendroctonus ponderosae) infestation in ponderosa pine (Pinus ponderosa) stands on 12 million acres of the Front Range of Colorado. Subsequently an in-place inventory was performed with the photography and ground sample data. The total number of trees killed in the Front Range was estimated to be 80,000, with a standard error of 15.7 percent. The cost for this survey was one cent per acre. With the same high-altitude photography, an in-place survey of a smaller area within the Front Range estimated 6,600 trees killed; the standard error was 4.7 percent. This survey cost two cents per acre.
