Beaver are generally assumed to have become extinct in Iowa, therefore the average Iowa citizen is startled when newspapers announce in headline type beaver activity in some apparently remote district of the state.

In fact, the increase of beaver population the past four years has now reached a point where their management presents a definite conservation problem.
