Abstract
La presente investigación se realizó en el sector de Trapichuco, barrio Lavandero, parroquia de Ambuquí, cantón Ibarra, el objetivo cuantificar la biomasa subterránea (radicular) en el sector de Trapichuco aplicando el método destructivo en especies forestales de espino y guarango que permita fortalecer la propuesta de conservación y servicio ambiental del área de estudio. Para la estimación de carbono en la biomasa subterránea, en la fase de campo se recolectó datos sobre las especies muestreadas como: diámetro altura del pecho (DAP), altura del árbol, altitud, coordenadas; además se utilizó el método directo o destructivo, que consiste en la excavación y extracción del árbol con todas sus raíces, tanto de la raíz principal y secundarias. Fueron llevadas al laboratorio para su respectivo lavado, pesaje y secado. Con estos datos se realizó el cálculo y análisis, para esto se tomó como base la metodología de biomasa aérea, la ecuación de biomasa subterránea del Ministerio del Ambiente. El resultado obtenido de biomasa subterránea en la zona de estudio es de 14,38 t en un área de 24,22 hectáreas. Con esta investigación se destaca la importancia ecológica que tienen los ecosistemas xerofíticos debido al aporte de servicios ambientales y captura del carbono, su importancia de conservación ecosistémica relacionados con los ciclos hidrológicos, sumideros de carbono, etc., que requiere ser conservada por tratarse de un ecosistema intervenido con escasos remanentes de vegetación nativa, producto del asentamiento y actividad productiva de la población.
The present investigation was carried out in the sector of Trapichuco, Lavandero neighborhood, parish of Ambuquí, canton Ibarra, the objective to quantify the underground biomass (radicular) in the sector of Trapichuco in forest species of hawthorn and guarango, applying the destructive method to strengthen the conservation and environmental service proposal of the study area. For the estimation of carbon in the underground biomass, in the field phase collected data on the species sampled as: diameter of the chest height, height of the tree, altitude, coordinates; In addition, the direct or destructive method was used, which consists in the excavation and extraction of the tree with all its roots, both the main and secondary roots. These were brought to the laboratory for their respective washing, weighing and drying. With this data was made the calculation and analysis, for this was taken as a basis the methodology of aerial biomass, the equation of obtaining underground biomass of the Ministry of the Environment. The result obtained from underground biomass in the study area is 14.38 t in an area of 24.22 hectares. This investigation highlights the ecological importance of xerophytic ecosystems due to the contribution of environmental services and carbon capture, its importance of ecosystem conservation related to hydrological cycles, carbon sinks, pollination of plants and dispersion of seeds, etc., which needs to be conserved because it is an ecosystem intervened with few remnants of native vegetation, product of settlement and productive activity of the population.
