View animated maps showing annual observations of insect activity as detected during aerial 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.
Maps will automatically advance every 2 seconds (or every 4 seconds for the slow versions) until the final cumulative map is reached. To restart the animation, click on the "refresh" icon at the top of your browser.
