Invasive species are species that are not native to Minnesota and cause economic or environmental harm or harm to human health. Minnesota's natural resources are threatened by a number of invasive species such as zebra mussels, Eurasian watermilfoil, common buckthorn, and emerald ash borer. Invasive species can occur on land or in the water.   Therefore, the QDMA surveyed every state and provincial deer project leader and asked them to provide 10 of the top naturally occurring native herbaceous and shrub species that whitetails use in their jurisdiction.
