Abstract

Global warming as a result of the increase in greenhouse gases symbolizes a great threat to life on the planet, with the passage of time it has been reflected in the increase in temperatures causing major disasters and altering physical, biological and human systems, so it is sought mitigate its effects and preserve biodiversity. Therefore, the present research proposed to estimate the content of carbon sequestered in the natural grasslands of the Ichubamba Yasepan protected area, with the purpose of establishing the amount of carbon present in necro mass, biomass and soil stored in the high Andean natural grasslands to have real data for future negotiations of environmental compensations and thus contribute to the reduction of greenhouse gas emissions associated with deforestation and environmental degradation. In the grassland and shrub ecosystems 4 plots were established and sampling units of square shape with dimension of 10 x10 m were installed, two circular plots with a radius of 5 and 2.5 m were installed, 8 quadrants of 50 x 50 cm were formed according to the GLORIA methodology, where they were collected 18 necromass samples, 18 aerial biomass samples and 16 soil samples. These were processed in the laboratory of the Faculty of Natural Resources (FRN) of the Polytechnic School of Chimborazo (ESPOCh). For the statistical analysis, a database was built that was processed using the InfoStat statistical package, where values between 6.14 and 7.22 Ton C * ha-1 of biomass, 1.74 and 11.55 Ton C * ha-1 in necro mass and according to the depth of the soil of 30 to 60 cm the amount of 93.98 Ton C * ha-1 was determined , obtaining as total results 170.8 Ton C * ha-1 in the shrub vegetation corresponding to 220,690.68 tons of total carbon in an area of 1292.1 hectares, while the grass vegetation registered 178.7 Ton C * ha-1 corresponding to 625,097.96 tons of total carbon distributed in 3498.03 hectares, which affirms that these ecosystems are huge carbon containers since vegetation cover absorbs CO2 from the environment, stores part of the carbon and returns oxygen to the atmosphere, all this through the process of photosynthesis, which prevents the destruction of the ozone layer and strengthens the mitigation of climate change worldwide.
