A nice brief article from Nicole Strong in the April 2012 Journal of Extension:
Abstract: Pest Scene Investigators is a new Oregon State University Extension education program designed to provide current Master Woodland Managers with specialized knowledge and skills in forest health assessment, diagnosis, and management. Seventy-nine volunteers participated in this pilot program from 2008-2010. The program effectively changed participant behavior on their own properties, with over 80% having thinned, planted alternative species, or assessed their land for forest pests and disease. However, participants showed little interest or confidence in helping other landowners or in doing forest health education. The program will re-tool to incorporate increased support and collaboration to increase confidence in providing volunteer service.
