Aerial Detection Surveys (ADS)
Every year since 1947, aerial detection surveys (ADS) 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 USDA Forest Service Forest Health Protection staff.
Digital data from these annual surveys are available from 1947 through the present year and maps are available from 2003 through the present year.
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 from 2005 to the present.
Aerial survey observations and other data have been summarized in Forest Health Highlights, Forest Insect and Disease Conditions, and other related reports.
