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.

Jennifer walked into her college radio station as a 17-year-old freshman and never looked back. Even though she was terrified of the microphone back then — and spoke into it as little as possible — she loved the studio, the atmosphere and, most of all, the people who work in broadcasting. She was hooked. Decades later, she’s back behind the radio microphone hosting Maine Public Radio’s flagship talk program, Maine Calling. She’s not afraid of the mic anymore, but still loves the bright, eclectic people she gets to work with every day.
Cindy helps produce Maine Public's live call-in show Maine Calling, and sometimes hosts the show—as well as the All Books Considered Book Club. Her first foray into journalism after graduating from Columbia University’s Graduate School of Journalism was to intern with CNN in China in the wake of the Tiananmen Square massacre. She then worked in print journalism over the decades, as a factchecker, writer and editor, with publications ranging from the Los Angeles Times Magazine to the magazine of the National Zoo to a food trends magazine.
