Description: DescriptionThe Forest Health Protection staff of the Pacific Northwest Region provides assistance and expertise to Federal, State, and Tribal land managers in Oregon and Washington concerning forest health conditions and issues. Forest Health provides advice and support for projects to help prevent or suppress insect and disease outbreaks. Annually, surveys are conducted to monitor forest health conditions and provide land managers with information on current issues, with an emphasis on detecting insect and disease activity.The Forest Health Protection program is a part of the USDA Forest Service and works collaboratively with Oregon Department of Forestry and Washington Department of Natural Resources to conduct annual aerial detection and ground surveys of forest health conditions. Satellite remote sensing is also used to gather information on forest health conditions. These surveys assess forest insect and disease issues throughout the Pacific Northwest Region (Oregon and Washington). This includes damage such as tree mortality caused by bark beetles, tree defoliation by leaf/needle feeding caterpillars, tree discoloration or branch flagging caused by pathogens, and abiotic factors like drought and hail damage.Data Disclaimer The USDA Forest Service makes no warranty, expressed or implied, including the warranties of merchantability and fitness for a particular purpose, and assumes no legal liability or responsibility for the accuracy, reliability, completeness, or utility of these geospatial data, or for the improper or incorrect use of these geospatial data.
