Invasive Species: Which ones should we worry about?

Invasive species are introduced plants or animals that spread and compete with native species. Most introduced species are not invasive, but a small number are. Invasive plant species are mostly introduced by the worldwide horticulture trade, though some are introduced by government bodies such as the Natural Resource Conservation Service. Many species listed as invasive do little harm, but often great effort and expense are devoted to extirpating them. With an emphasis on trees and shrubs, we will discuss why some invasive species are more troublesome than others, and you may be surprised at what we discover in our discussion.

This is a Zoom webinar. There will be ample opportunity for participants to post questions.
