Join the Texas A&M Forest Service and the Texas Chapter ISA for the Oak Wilt Identification and Management Qualification Course and Assessment. This two-day workshop is for ISA Certified Arborists and will show you how to identify and manage oak wilt in Texas.

Each participant that successfully completes the course and passes the assessment will receive the status of Oak Wilt Qualified. Their qualification will be noted on the Texas Oak Wilt website as well as on any handout and other materials referencing qualified individuals. Dr. David Appel, Texas A&M and Robert Edmonson, Texas A&M Forest Service will be conducting the training.
