Six Species Added to Michigan’s Invasive Plant Lists Following MI Commission of Ag & Rural Development Vote!
On May 20, the Michigan Commission of Agriculture and Rural Development approved the addition of six species to Michigan’s invasive plant lists under Part 413 of the Natural Resources and Environmental Protection Act (NREPA).
Pursuant to the Commission’s decision, the following four plant species will be added to the restricted species list. Effective January 1, 2028, it will be unlawful to introduce, import, sell, possess with intent to distribute, or intentionally propagate these species in Michigan:
Common buckthorn
Glossy buckthorn
Callery pear
Japanese barberry
The following two plant species will be added to the prohibited species list. Effective June 19, 2026, it will be unlawful to introduce, import, sell, possess with intent to distribute, or intentionally propagate these species in Michigan:
Water hyacinth
Water lettuce
Under Part 413 of NREPA, invasive species are defined as species that are not native to Michigan and that cause, or are likely to cause, harm to the environment, economy, and/or human health. Regulating invasive species helps limit their introduction and spread through sale, trade, transport, and intentional propagation. Prohibited species are not widely distributed in the state and pose a significant risk to human health or natural, agricultural, or forest resources, with limited effective management techniques available. Restricted species are already more widely established in Michigan but still pose risks to human health or natural, agricultural, or forest resources.
Property owners are not considered in violation if these invasive species are already established on their property or in adjacent waterways. Individuals who seek alternatives to the newly restricted and prohibited plant species are encouraged to review resources such as those compiled by the Northwest Michigan Invasive Species Network.
