On August 24th a Japanese stilt grass population was confirmed growing in a natural area in McHenry County. This is the most northern population in Illinois that I am aware of and extremely concerning given the next closest known population is in Will County. Partners, land owners, stewards and recreationists need to be aware of this species and alert for the presence of other populations in our region. Please report any populations you think might be Japanese stilt grass. This species, an annual grass, can spread very quickly via seed and establishes dense populations in floodplaines, wetlands and other seasonally wet areas. Now is the time to stop the spread of Japanese stilt grass into northern Illinois.
