We asked:
1. Can a presentation about forest modeling increase knowledge about forest processes in members of the public?
2. Do computer visualizations and animations enhance effectiveness of such a presentation?
3. Do formal presentations influence public perceptions of the Forest Service and forest management?
4. Do visualization and animation affect these perceptions?

Conclusions
1. Presentations can enhance understanding of forest processes and models.
2. Visualization & animation may increase understanding for some audiences (older or less educated?)… and people like it!
3. Presentations may increase agency credibility
4. Visualization & animation unlikely to increase credibility
5. Presentation quality matters5. Presentation quality matters
