262 cades for Dutch elm disease to spread in the United States (Duffy 2009), but recently daylily rust (Puccinia hemerocal- lidis) spread from coast-to-coast in one year (Bergeron 2008). This study showed that education on the need for plant spe- cies diversity in the green industry is important. Regardless of the level of familiarity with the issues, the attitudes expressed in this study, generally, were not strongly held. Such attitudes are much easier to change than strongly held ones (Schafer and Tait 1986), and so it is likely that increased education on the issues would raise awareness. This could come through formal university classes that train the next generation of hor- ticulturists and landscape architects, or in trade journals and articles, which were cited by nearly 70% of respondents in this survey as being a source of information on this subject.
