Many years prior to the settlement of Iowa her streams had been scoured by Indian hunters and white trappers for fur, principally beaver. The hunters and trappers had taken the cream of the beaver before the earliest settlements were established; however, remnants of the population were still present as is attested to by the fact that Iowa geography has many names alluding to the beaver. Beaver could not stand both persecution and civilization, so they disappeared from Iowa sometime after the seventies and in 1872 the legislature placed them on the "continuous closed season" list. By the late twenties there were rumors of beaver in Iowa again along the Missouri River in Woodbury County, and in 1930 their residence in the state was definitely established. By 1937 the appearance of colonies in unwelcome locations and the desire to aid the spread of this valuable forbearer caused the Conservation Commission to inaugurate a live trapping, stocking program (Anon., 1943).
