This study investigated the practices, challenges, and needs of Chesapeake Bay watershed outreach professionals, as related to behavior change strategies and best outreach practices. Data were collected through a questionnaire e-mailed to applicants to the Chesapeake Bay Trust's environmental outreach grant program (n = 108, r = 56%). Almost all respondents seek to change adult audiences' behaviors and reported using a range of behavior change strategies and best outreach practices. However, it is not clear that many use behavior change strategies intentionally or fully implement best outreach practices. Recommendations are offered for how funders can help outreach professionals better meet mutual environmental behavior change goals. (Contains 8 tables and 5 figures.)
