Forest Insect & Disease Aerial Survey Data
The maps listed below 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. Maps including "draft" in their names may be updated pending review by survey specialists.
Each map is a 1 to 2 MB pdf file. These files are best viewed with Adobe Acrobat Reader Version 6.0. These files will take anywhere from 1-2 minutes to completely load to your screen (the screen will be blank until it downloads completely). Your other option is to 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.
Warning! Due to problems with our national Forest Service webserver, large .pdf or .zip files (such as most map files on this page) may not load correctly. If you encounter this problem, consider trying again later (the problem is intermittent), or during non-business hours. You can also contact Julie Johnson or Kathy Sheehan to receive specific files by email. We encourage Forest Service users who encounter problems to submit tickets to EUSC to raise the visibility of this problem.
The survey data used in creating draft maps is not available for download. However, when final maps are posted, shapefile and .e00 zip files covering the extent of Oregon and Washington are also posted.

You may also contact your local Forest Health Protection (FHP) Service Center for more information. There are five service centers in Oregon and Washington providing assistance to federal resource managers. These offices are located in: Wenatchee, Washington; Bend, La Grande, Medford, and Sandy, Oregon.
Similar aerial survey maps are now available online for parts of the Rocky Mountains (Colorado, Nebraska, Kansas, and parts of Wyoming and South Dakota) and the Lake States (Minnesota, Wisconsin, Michigan, Indiana, Illinois, Iowa, and Missouri). Access much of this data interactively at the new FHP Geospatial Portal.
Our Canadian colleagues with the British Columbia Ministry of Forests and Range have aerial survey information available online in the form of reports, maps, and tables.
