The Great Western Root - Construction and Consideration of Behavioral Chains Relative to Resource Management

Perideridia spp., commonly known as ipos or yampah, have provided major subsistence crops for groups throughout Western North America.   Ethnobotanical material available concerning this use suggests that management strategies might have been practiced by these groups to enhance the resultant crop yield.   These strategies included fire management, ground disturbance and selective harvesting techniques.   Behavioral chains will be constructed in this paper utilizing this ethnobotanical information.   These chains, as well as a consideration of their potential biogeographical implications, should help in the paleoethnobotanical determination of past use and management of this resource.
