Of the 328 total respondents 32% identified themselves as commercial arborists. An additional 17% associated themselves with other arboricultural affiliations to raise the total to 55%. The remaining 45% assorted themselves within a dozen other urban vegetation management disciplines. Of 12 possible choices, information about tree maintenance, and insect and disease controls was listed as a primary concern by the respondents. As reported, the largest number of contacts for information (18 choices) was made with county extension agents, product dealers or suppliers, and the ISTC. An analysis of and recommendations for more effective information exchange is provided.
