This research provided information on the carbon storage capacity of Andean forests, fulfilling the objectives of determining the above-ground biomass content and estimating the fixed carbon in a permanent plot of Andean forest in the Cajanuma sector, Podocarpus National Park, Loja province. The study was carried out in a permanent plot of 1 hectare (100 m x 100 m) divided into 25 subplots of 400 m2 (20 m x 20 m); the diameter and height of all trees with DBH ≥ 10 cm were measured; The amount of biomass of each tree was estimated by using an equation that relates height, diameter and density of wood. For the shrub and herbaceous strata, the destructive method was used, taking samples of the vegetation (shrub and herbaceous) in 20 plots of 4 m2 placed around the 1 ha plot, which were weighed in green and then dried in an oven at 60 ° C to estimate the biomass content through the green weight-dry weight ratio. In the case of Rhipidocladum harmonicum, which is an abundant floristic element in this ecosystem, the average biomass of a stem was estimated by relating the green weight-dry weight of 30 stems of this species. To estimate the carbon content, the estimated biomass of each stratum was multiplied by 0.5. The results showed that the estimated carbon content for the tree stratum with a record of 1506 individuals ≥ 10 cm DBH was 70.86 Mg ha-1; for the shrub stratum the estimated carbon content was 6.08 Mg ha-1; for the herbaceous stratum, the carbon estimate was 0.09 Mg ha-1, giving a total carbon fixed in the plot of 77.02 Mg. It was determined that in 1 ha of Andean forest the trees capture 92% of the total carbon, the shrubs 7.89% represented mainly by Rhipidocladum harmonicum and the herbs 0.11% this in terms of aerial biomass, however, it is necessary Carbon content research for other floristic elements such as lianas, epiphytes, as well as forest necromass, which can be included in future studies. Key Words: Andean forest, carbon, biomass, ecosystem services. |
