Organic tree fruit research priorities. Organic tree fruit growers in the Pacific Northwest participated in a series of real-time surveys of organic tree fruit problems, research needs, and priorities. The surveys were held during various educational meetings, using the Turning Point audience participation technology.  Overlap between meetings in a given year was less than 30% of the audience.  Survey questions were adjusted somewhat for each meeting, depending on the topic of interest. A number of questions were the same for all meetings.
