Levien, USDA Forest Service, 1920 20th Street, Sacramento, CA 95814; (916) 454-0803; llevien@fs.fed.us Chris S. Fischer, Lianne C. Mahon, and Jeff A. Mai The US Forest Service (FS) and California Department of Forestry and Fire Protection (CDF) are conducting a monitoring project for Sudden Oak Death (SOD). Multi-scale remote sensing, aerial surveys and on the ground sampling form baseline information to identify areas affected by SOD. The project area spans from Humboldt County to Monterey County. Baseline land cover change data were derived using Landsat Thematic Mapper (TM) satellite imagery, employing a multi-temporal Kauth –Thomas transformation. Two-meter digital camera imagery was acquired from flights over the project area and, in conjunction with the satellite derived data, aided in identifying the extent of oak mortality. Aerial surveys were conducted to provide another means for detection and monitoring. Mortality areas were identified visually, sketch mapped and photographed on 35mm color film. A handheld Global Position System (GPS) was used to record the flight line and pinpoint potential SOD sites. Field verification is imperative to confirm or refute the presence of the disease, as well as validate the satellite derived data, and will be conducted at a future date. This collaborative effort streamlines field confirmation of areas affected by SOD and is prerequisite to the identification of future management opportunities.
