Aerial Detection Surveys (ADS)
Every year since 1947, aerial detection surveys have recorded the insects and diseases affecting forests in Oregon and Washington. These annual surveys are cooperative efforts by the Forest Health staffs of the Washington Department of Natural Resources, Oregon Department of Forestry, and the U.S. Forest Service Forest Health Protection staff.
Digital data and maps are available for 1980 through the present; survey data from earlier years are being digitized.
A data dictionary describes the available data files and their contents. View flight lines showing the paths of the survey aircraft for each year, color-coded by date. Learn more about current aerial surveys. Maps based on aerial survey data can also be generated interactively through the FHP Geospatial Portal for 2005 and following years.
Aerial survey observations and other data have been summarized in Forest Health Highlights, Conditions Reports, and other related reports.
