Aerial Insect and Disease Detection Survey(ADS) for insect and disease activity in 2004. The ADS data was obtained to be used for BLMs REA Process for the Middle Rockies ecoregion. The original data was combined from USFS regions within the ecoregion then clipped to the Middle Rockies Level III ecoregion plus a buffer that consists of the 5th level Hydrologic Unit Code (HUC) watersheds that intersect the ecoregion.
