This plant is native to Europe and Asia. Because the roots are edible, it was brought to the United States and planted as a food source. It escaped cultivation and is now a widespread invasive plant across the United States.
Exotic and invasive plants, like wild parsnip, can out-compete native plants. This can cause a native plant community to shift to a field of exotic species and possibly remove important food sources for animals. Warning: Visitors should be aware of wild parsnip and how to identify the plant. This plant, when cut or disturbed, produces a toxic juice. If the juice contacts the skin and reacts with sunlight, it can cause severe rashes and burns. This condition is known as phytophotodermatitis. Voyageurs National Park recognizes the negative effects wild parsnip has on the ecosystem. Staff members are taking steps to eliminate this plant from the park. Careful use of herbicides has been effective in treating patches of wild parsnip within the park. Cutting flower heads before going to seed can also prevent the plant from spreading.
