Webinar-Tree Diversity and Exotic Threats: The 5% Solution

Loading Events
Presenter: Dr. John Ball, South Dakota State University. With increased international trade our urban forests continue to experience a plethora of stress-factors that include a continuing assault from exotic pest threats. Diversification related to urban tree selection is one important component of plant health care. Dr. John Ball will outline proper steps to choosing urban trees, with emphasis for diversity being at the genera, not species, level. This presentation will explain why the old “10-20-30 rule” needs to become simply “the 5% solution.”
