We employed paleolimnological methods to investigate tropical forest recovery and soil stabilization that followed abandonment of agricultural systems associated with disintegration of Classic Maya polities ca. A.D. 800–1000. We used lithological, geochemical, magnetic, and palynological data from sediment cores of Lake Petén Itzá in the Maya Lowlands of northern Guatemala. Sediment core chronology was developed using radiocarbon dates on terrestrial wood and charcoal fragments. Our results indicate that in the absence of large human populations and extensive farming activities, Petén forests recovered under humid climate conditions within a span of 80–260 yr. Soil stabilization postdates pollen evidence of forest regrowth stratigraphically, and required between 120 and 280 yr. We conclude that the tropical forest ecosystem in the watershed of Lake Petén Itzá had been reestablished by the early Postclassic Period (A.D. 1000–1200).

Resumen en inglés

Integrating history, biodiversity, ethnobotany, geology, ecology, archaeology, anthropology, and other disciplines, The Lowland Maya Area is a valuable guide to the fascinating relationship between man and his environment in the Yucatán peninsula. This book covers virtually every aspect of the biology and ecology of the Maya Lowlands and the many ways that human beings have interacted with their surroundings in that area for the last three thousand years. You'll learn about newly discovered archaeological evidence of wetland use; the domestication and use of cacao and henequen plants; a biodiversity assessment of a select group of plants, animals, and microorganisms; the area's forgotten cotton, indigo, and wax industries; the ecological history of the Yucatán Peninsula; and much more. This comprehensive book will open your eyes to all that we can learn from the Maya people, who continue to live on their native lands, integrating modern life with their old ways and teaching valuable lessons about human dependence on and management of environmental resources."
