The history of ciénegas in the American Southwest over the last 8,000 years provides information on the dynamics of growth, longevity, and stability of these wetland habitats under previous climate conditions. Ciénega surfaces alternate between wetland and dryland phases, identified by changes in pollen preservation and isotopic signatures. This study presents a conceptual model on the controls for different ciénega states and how the paleoenvironmental record of change can be used in conservation, restoration, and management of these critical habitats.Download file (1MB)
