Invasive Plants: Identifying Problematic Plants That Cause Harm & Learning How to Prevent and Remove Them

Bill Johnson

There's growing awareness of the damage caused by invasive plants— from the purple loosestrife ubiquitous along roadways to the Norway maple so prevalent in towns and cities. Currently, a state committee is working to expand the list of plants that will be banned for sale in Maine. We will learn about some of the most problematic invasives, how to identify them, ways to eradicate them—or prevent their spread. We’ll hear about aquatic invasives, as well as managing invasive plants on land trusts.
