To celebrate ArborViews’ two-year anniversary we invited one of our favorite guests, Dr. Michael Raupp, who was the very first guest in the debut of our series in 2010! In this episode, Dr. Raupp talks, to our host Mark Hartley, about the invasion history of non-native insect pests and the impact on urban forests. Dr. Raupp (yes, ‘www.bugoftheweek’ guy!) talks about what we can do as arborists to prevent the possible catastrophic consequences of invasive pests.
