USFS Region 6 forest insect and disease aerial detection survey, including years 2007-11. Clipped to SWO.
Each year, all forested federal, state and private land in Oregon and Washington are aerially
surveyed for insect and disease damage.
This survey is flown cooperatively by the Region 6 US Forest Service,
Forest Insects and Diseases group; the Oregon Department of Forestry, Insect
and Disease Section; and the Washington Department of Natural Resources. This data is collected to determine regional
insect and disease trends and to serve as an indicator to land owners/managers
on insect and disease activity in their area.
