This study of 23 pollen samples allows recognition of a sequence of ecosystem changes occurring in central New Mexico between A.D. 1280 and 1400 and also in the 1650 - 1750 period. It also discusses the effects of such changes on aboriginal maize agriculture. Draft of the report included in Archaeological Excavations at Pueblo del Encierro.
