Invasive Plants in Monroe County, Indiana

While approximately 25% of the plant species found in Indiana are not native to the state, the vast majority of them are NOT invasive. That is, they do not move outside of cultivation and cause economic or environmental harm, or harm to human health.  Those non-native species that do cause harm - by impacting forests, wildlife, wetlands, agriculture, or other important resources - are considered invasive.  The members of MC-IRIS developed a list of the invasive plant species of concern in Monroe County, and then voted on which were causing or had the potential to cause the greatest damage.  More information on the Top 10 Invasive Plants can be found here.
