Western North American Defoliator Working Group
The purpose of the Western North American Defoliator Working Group (WNADWG) is to provide a means to address issues associated with western defoliator ecology and management. The WNADWG meets annually or more frequently as needed. The group is composed of professional forest pest management specialists, scientists, and resource management specialists representing federal, provincial, state and local governments, universities, and private interests.
Specificially, the WNADWG provides a forum to:
-
Discuss current defoliatior conditions in Western North America
-
Identify and discuss issues and concerns related to western defoliator ecology and management
-
Address short- and long-term research, technology development and management needs for western forest defoliators
-
Communicate issues, concerns, recommendations, priorities and needs to appropriate entities

Next Meeting
Due to budget and travel constraints, the 2011 meeting has been cancelled. Please send digital versions of regional and state reports regarding western defoliators to Beverly Bulaon by January 15, 2012. These reports will be collated and sent to participants, and posted below. Options for the 2012 defoliator meeting will probably be discussed at the March 2012 WFIWC in Penticton, BC.
