Historical Note

By letter of September 26, 1923, the Chief of the Bureau of Biological Survey requested from the National Park Service yearly "information as to the number of the different kinds of big game animals in the various national parks, for use in reissuance of lists of national and state game and bird refuges." In 1937, the Biological Survey began annual inventories of big game throughout the country, compiling these statistics from estimates of the National Park Service, Forest Service, and its own field agents and cooperative units.
