Invasive, non-native plants crowd out the native plants that indigenous creatures rely on for food, breeding and nesting, shelter, shade and more. Some invasives are quite beautiful – but they throw nature's balance out of kilter. Local streams have been particularly hard hit.The invaders, including Japanese Knotweed, multiflora rose, barberry and Purple Loosestrife, move quickly and can completely dominate a stream within just a few seasons.
