Forest Park is America's largest urban forest.
Its native plant species, which provide habitat for the native wildlife, is being overpowered by invading, introduced plants. The worst is English Ivy. Brought by early settlers, Ivy escaped from homesites and became established in Forest Park. Our temperate rain forest provides its ideal growing conditions - we're like Ivy heaven to it. It suffocates ground cover, smoothers native plant seedlings, overwhelms shrubs, destroys trees, and provides no food for native wildlife.
