About Aerial Detection Surveys
These maps are based on cooperative aerial surveys conducted by Forest Health Protection staffs of the Oregon Department of Forestry, Washington Department of Natural Resources, and the USDA Forest Service Pacific Northwest Region.
Each map is a 1 to 6 MB pdf file -- select a year (above), then click on a quad to view a map. You can also save the file to your local disk and view/use/print it from there. Zoom views can be printed on 8.5 x 11 printers, while full maps are best printed at 36" x 36" on a full scale plotter. View suggestions for using pdf files. Download the aerial survey data on which these maps are based.
These maps can also be created interactively at the FHP Geospatial Portal for 2005 and following years.
