Abstract

Three pollen profiles reveal vegetation changes during the past 16,500 years of the Podocarpus National Park (PNP) in the Southern Ecuadorian Andes. Andean glaciers retreated after the Last Glacial Maximum and the Younger Dryas cold interval, accompanied by a marked decline of páramo vegetation between 11660 and 4280 b.p., and the expansion of subpáramo vegetation. Polylepis was widespread during the warm early Holocene, whereupon páramo vegetation increased after 4200 b.p. The upper montane forest became abundant after 4200 b.p., and an increase of páramo taxa since 500 b.p. indicates moister climate since then. Charcoal particle concentration maxima are evident between 1800 to 1600 b.p. and 600 to 400 b.p. The mountain region became permanently settled at the end of the nineteenth century when the exploitation of natural resources was initiated. Decadal variations in ring-width chronology from Cedrela montana are possibly related to large-scale atmospheric pressure variations in the tropical Pacific Ocean.
