North America has a history of exotic pests that extirpate individual tree species, with Emerald Ash Borer serving as our modern example. In our current, ever-globalizing society there is significant risk for future outbreaks that may impact our trees from the urban forest to our woodlands. Join University of Illinois Extension Horticulture Educator Ryan Pankau as he examines past outbreaks on our continent to compare what we have learned historically with the current pests threatening our native trees.
Each program is recorded and uploaded to Illinois Extension Horticulture YouTube channel. To allow time for closed captioning edits, please check the YouTube channel about two weeks after the scheduled program.
