APPENDIX 2

Invasive Species
The species listed below are non-native, invasive plants in Michigan. Once introduced, these  plants can aggressively colonize natural areas, decreasing biodiversity and compromising the  ecological integrity of an area. Member nurseries are expected to actively manage for the  prevention of distribution of plants or seed of any of these invasive species.
This list was compiled by Greg Vaclavek for the Michigan Native Plant Producers Association.
