Abstract

An intensive study of the occurrence and use of duck food plants in the Illinois River valley was conducted 1938-1940. A preliminary report covering the results of the 1938 investigation was issued (Bellrose and Anderson, 1940). Altered water levels in 1939 and 1940 greatly changed the food resources of many bottomland lakes through the development of extensive communities of moist-soil plants.  This paper summarizes the data for 1938-1940.
