Survey of Wholesale Production Nurseries Indicates Need for More Education on the Importance of Plant Species Diversity    (View PDF)

Nicole R. Polakowski, Virginia I. Lohr, and Teresa Cerny-Koenig

Abstract: Recent pest outbreaks, such as emerald ash borer and Asian longhorned beetle, have renewed concerns about the lack of genetic and species diversity in landscapes across the United States. However, the level of understanding of these issues by people in the green industry is not known. A survey on the knowledge of plant species diversity issues was distributed to Washington, U.S., wholesale nurseries. Respondents indicated a general awareness of the issue, but they had insufficient understanding of why the lack of species diversity is a problem. Respondents who had learned about plant species diversity in educational settings beyond high school were more likely than others to understand the issues. These results indicate the need for increased, in-depth education on why plant species diversity among landscape plants is important.

Keywords: Biodiversity; Genetic Diversity; Nurseries; Overplanting.
