Abstract

Trough the analysis of grass phytoliths preserved in a sequence of buried soil horizons in the Lauder Sandhills, southwestern Manitoba, this article reconstructs a local grassland fire record for the past 5,000 years. The A. proposes that an apparent peak in fire frequency shortly after 2,500 C 14 years B.P. corresponds to the deliberate burning of prairie by Sonota-Besant (Plains Woodland) hunter-gathers, rather than climatic forcing. This practice, which is clearly documented in the historic record, may have functioned as a means of making bison-herd movements more predictable and may have enabled higher human carrying capacities in the Plains Woodland period
