Content

The Tropical Pacific region in Colombia is the rainiest in America. Short and scarce instrumental meteorological data are a frequent drawback in South America. Tropical dendrochronology can potentially provide long-term climatic records extremely needed considering first, the lack of climatic data for feeding the global climate models for this region, and second, the high ecosystem and population vulnerability to the ongoing climatic change. Prioria copaifera, known as cativo, is a tropical tree-legume species growing in the floodplains of the low Atrato River that cross the Colombian Pacific through the north, close to the Pacific Ocean. Here, we demonstrated that P. copaifera forms annual rings with the generation of reliable tree-ring chronology with significant correlation with climatic variables. This annuity was also confirmed by several 14C dates and a reconstruction of the water level for the Atrato river was performed for the last 150 years. Our reconstruction was strongly related with the ENSO phenomenon.
