USING EURO-AMERICAN HUNTING DATA TO ASSESS WESTERN GREAT PLAINS BIOGEOGRAPHY, 1806—35

Historic accounts from the 19th-century western Great Plains contain significant information on Plains ungulates and other animals, particularly as they relate to provisioning the Euro-American travelers. Using data derived from these accounts, a quantitative assessment of the hunting success of the Pike, Long, Glenn, and Dodge expeditions of the early 19th century is presented to ascertain the conditions of these species in the region. These data are then used to assess historiographic models of bison overhunting. This analysis indicates that the western Southern Plains and western Central Plains had differing trajectories of overhunting explained by temporally variable human and environmental impacts.
