Jane Kaufman reports in The Berkshire Eagle that the invasive plant garlic mustard, with no natural predators, is taking over the roads and trails of Mount Greylock. Officials from Massachusetts Department of Conservation and Recreation have an ongoing effort to keep the tall fields of green and white garlic mustard in check. Kristina Stinson, associate professor of plant ecology and conservation at the University of Massachusetts at Amherst, says the soil in the Berkshires seems to be more susceptible to invasion by garlic mustard than other areas in the state. The plant blocks out local plants and butterflies. Stinson said, “Because it has an impact on tree seedlings, it is really impacting the future canopy of our forest.” Right now is the time to remove garlic mustard, and it needs to be pulled once it emerges in spring but before it seeds, typically in early to mid-July.
