This research project has information that is handled for basic reference and other purposes, on the estimation of carbon sequestration in the natural forest secondary. It is very important the result; since it can 'be work future projects to the decrease of atmospheric concentrations through the capture of atmospheric carbon (absorption by natural stores). Our region has the highest rate of deforestation at the national leve! by releasing enormous amounts of carbon dioxide which are leading to changes in climate and environmental quality. lt is therefore very important that the research was conducted in the Pabloyacu Research and Production Center , there are initiatives both of teachers as professionals and graduates students in conductii1g research in that place. The entry into force of the Kyoto Protocol and the clean development mechanism opens up the prospect for the forestry produ...
