When plants are introduced to a new location, either intentionally or accidentally, they can spread prolifically, out-compete native species for resources, and eventually even dominate the landscape. Biologists are studying the mechanisms underlying a taxon’s ability to become invasive, but it can be difficult to predict whether or not a species will become invasive in a new habitat. With an increased awareness about the environmental and economic threats posed by invasive species, the Chicago Botanic Garden has expanded and strengthened its invasive plant policy. The Garden aims to strengthen its role as a conservation leader without compromising its horticultural mission or the beauty of its landscapes.
