Invasive Species Management

Invasive species are non-native plants and animals that aggressively displace native wildlife species. Invasive plant species often out-compete native wildflowers and other plants for space, light, or water. This can reduce diversity in affected areas to a low-quality habitat of a few invasive species.

In our park system Bush Honeysuckle, Autumn Olive, Tree of Heaven, and Garlic Mustard are the most dominant invasive pests. Our focus is on removing invasive species in areas that have existing native plant communities threatened by invasives.

invasive Current methods of invasive control include cutting, pulling, and the use of herbicides. Pulling Garlic Mustard is a great way to get large groups involved in invasive control. It is important to note that the entire plant must be disposed of in the trash, burned, or buried deeply to keep seeds from germinating.

Woody invasives such as Bush Honeysuckle, Autumn Olive, and Tree of Heaven often vigorously re-sprout after being cut, which makes cutting alone unsuccessful at killing the plant. Experience indicates that the responsible use of herbicide often plays an essential role in removing invasive plants.
