Some trees, shrubs, and other plants are not recommended for planting because they are considered invasive.
Invasive plants have a tendency to spread and disrupt ecosystems in natural areas such as state and national parks and forest preserves. They can out-compete native plants, upsetting the balance of the ecosystem. They can make the habitat less suitable for native plants and animals. Invasive plant species are a significant and ongoing land management concern.
