Biomasa vegetal en zonas degradadas por minería en un bosque pluvial tropical del Chocó Biogeográfico Plant biomass in degraded areas by mining in a tropical rain forest of the Chocó Biogeographic

The aim of this work was to study the changes of plant biomass in primary succession after a forest mining in the municipalities of Certegui and Union Panamericana, Department of Choco, Colombia. For which, was evaluated by the method of chronosequence, aboveground and belowground biomass of five zones with different periods of time (between 1.5 and 6 years) after mining. Equations were used to calculate the carbon biomass of the plots and used a growth model of von Bertalanffy model the change in plant biomass over time. Generally found in areas with degraded by mining various stages regeneration occurred biomass values between 104.83 g m 2
