The River to River CWMA has updated its map of known locations for Japanese chaff flower. Currently, chaff flower is found in 9 counties in southern Illinois, mostly along the Ohio and Cache Rivers. The CWMA is planning further survey efforts for this summer and fall to look for new infestations as well. To learn more about Japanese chaff flower, read the 2011 Wildland Weeds article by Evans and Taylor at http://www.rtrcwma.org/chaffflower2011.pdf
