Aerial Insect and Disease Detection Survey(ADS) for Mountain Pine Beetle activity in 1994 - 2010. The ADS data was obtained to be used for BLMs REA Process for the Northwestern Great Plains ecoregion. The original data was combined from USFS regions within the ecoregion then clipped to the Northwestern Great Plains Level III ecoregion plus a buffer that consists of the 5th level Hydrologic Unit Code (HUC) watersheds that intersect the ecoregion.
