Game on, Garlic Mustard!


You’d scarcely think to look twice at it: to all appearances, garlic mustard (Alliaria petiolata) seems an inconspicuous bit of green in a sea of more green. Then time goes by…and it IS the sea of green! This pernicious invasive plant out-competes native species through a combination of its growth pattern (early emergence and large size help it win the competition for light and water) and allelopathy (releasing a substance from its roots that is toxic to native plants—think “chemical warfare”), making it a priority for removal. Once again this year, we have assembled a “task force” of volunteer interns to hand-pull this species over the next couple of months; we’ve already covered a lot of ground, and can tell that our efforts from previous years are paying off!
