In the last decade, anthropogenic activities such as deforestation, fires, timber extraction, expansion of the agricultural frontier, and extensive cattle and goat raising have impacted the regeneration capacity of the forests, leaving only 25% of the original dry forests as remnants. In the present study, the carbon stored in the aerial biomass and necromass in passive restoration areas of 20 years of dry forest restoration in the Laipuna Natural Reserve, in the province of Loja was determined. An inventory was carried out in four permanent plots of 2500 m² each, within which trees with a diameter at breast height (DBH) ≥ 5 cm were measured. For necromass information was collected from standing dead trees, fallen trees, and leaf litter. In the study area, 35 woody species were reported, corresponding to 31 genera and 19 families, being the most important species in carbon storage: Vachellia macracantha, Ipomoea wolcottiana, Erythrina velutina and Eriotheca ruizii. The component with the greatest contribution to carbon content is aerial biomass, representing 91% and storing an average of 26.09 tC/ha. In comparison, necromass represents 9%, storing an average of 2.67 tC/ha in 20 years of recovery. Cattle grazing in the reserve has affected carbon storage in the soil. Therefore, it is recommended that access to Laipuna Reserve be controlled to guarantee complete recovery in degraded areas. |
