The Llanos de Mojos is a tropical savanna in the Bolivian Amazon with strong seasonality. Abundant earthworks and anthropogenically shaped landscapes suggest that precolumbian inhabitants had a much larger impact on the region than previously believed. This study examines changes in the hydrological landscapes of the savanna as a proxy for precolumbian land-use practices over time in West Central Mojos. A sediment core from the Quinato Wetland was sampled for diatom analysis. Although diatoms were poorly preserved, they were present and had changing species compositions at different depths. Comparison to other diatom assemblages reported in the Quinato Wetland suggests that the diatom taxa present in individual sediment cores are distinctly shaped by the hydrological conditions at that location rather than the larger scale conditions of the entire wetland. Further diatom analysis could help identify location specific changes in water levels over time to reconstruct the timing of earthwork construction and maintenance. The application of diatom analysis methods to archaeological questions about land-use practices in West Central Mojos has the potential to demonstrate how large-scale human settlements in parts of the Amazon were made possible through the management of landscapes once thought of as untouched by human influence.
