Invasive Plant Species

Invasive species are non-native plants that cause damage to native ecosystems due to loss of diversity.  This can be detrimental to local economies, recreation, and environmental health. 

According to the WI DNR, approximately 42% of the species on the federal endangered species list or threatened endangered list are at risk primarily because of invasive species.  The DNR provides A Field Guide to Invasive Plants in Wisconsin.

Invasive plants should be removed and sealed in plastic bags to be sent to the landfill. Small bags can be placed in your green refuse cart and large bags can be disposed of at the Fitchburg Recycling Drop off site (2373 S. Fish Hatchery Rd) in the dumpster marked 'yardwaste bags, invasive plants and empty oil containers'.​
