摘要

In 1995 and again in 2000, Ohio's urban foresters (vegetation managers) were surveyed by mail. An article introducing them to 30 less commonly utilized trees was mailed along with each survey. The survey was designed to determine which of 120 trees Ohio's urban foresters might be requesting five years in the future (2000 and 2005). A total of 13 tree species increased in demand 100 or more while a total of 17 tree species experienced a decrease of 100 or more in demand between 1995 and 2000. In thelater 2000 survey, vegetation managers were also asked to determine if they believed that demand was decreasing or increasing for each plant they requested. Demand was uniformly spread across genetic families, as only Aceraccae (17.2 percent) was requested more than 9 percent of the time.
