La Crosse, Wis. — A new invasive species has been found and exterminated in La Crosse County. 

Experts with Wisconsin’s Department of Natural Resources found Japanese stilt grass at the Coulee Experimental State Forest this past July.

“We think that since this sight is being used by hunters and hikers, it most likely arrived here on someone’s clothing, their equipment, or the treads in their shoes,” says DNR invasive species expert Jason Granberg.  

Typically, Japanese Stilt Grass is found more towards the eastern part of the country. Granberg says it has, however, been spotted along the Illinois border. The problem with most invasive species, plant or otherwise, is it disrupts the proper growth of native species in that area. 

“It’ll grow so densely in the landscape and it’ll prevent other smaller plants from sprouting,” says Granberg on how Japanese Stilt Grass can be harmful.

The largest population of invasive species is found in Milwaukee, Wisconsin’s largest city. Roughly 45 different invasive plant species have been found there.

“Throughout the state, that number will be much higher because t’ll include insects and mammals and other things like that,” says Emilie Burmeister with Milwaukee County Parks.

Experts agree that the best way to prevent invasive species from spreading is to make sure outdoor gear is thoroughly cleaned. Bleach solution can be used to clean the bottoms of boats, or kayaks. Boot brushes are the best method to clean treads on hiking shoes.
