  • Challenge Question #1

    Using data from the population chart, make a graph to show the growth of the whooping crane population. Then see if you can answer this question:

    "During which decade did the population grow at the fastest rate? Why do you think this occurred? "

    (This question was asked as part of the March 5, 1997 Whooping Crane Migration Update).
