GREENSBORO – Greensboro Conservation Commissioner William Marlier spent the summer surveying and mapping the community’s invasive plants, and plans to share his findings and offer advice for combating these aliens at the Greensboro Free Library on Tuesday, Oct. 24, at 4 p.m. The USDA defines an invasive species as “an alien species whose introduction does or is likely to cause economic or environmental harm or harm to human health.” Some invasive plants can be poisonous or noxious and harm humans, pets, and/or wildlife. All invasive plants pose existential threats to our local biodiversity. Oftentimes native species are unable to compete with the foreign invaders, leading to loss of habitat and potential extinction. Marlier’s research positively identified communities of Japanese knotweed, goutweed, wall-lettuce, hedge bedstraw, garlic mustard, honeysuckle, common reeds, and many more species of invasive plants distributed all across Greensboro. His presentation will help the community to understand, identify, and manage these dangerous plants. All are welcome.
