Valoración económica del almacenamiento de carbono por biomasa aérea en bosques montanos de la cordillera occidental de los Andes

Abstract

Carbon storage and sequestration by montane Ecuadorian forests is poorly understood. These ecosystems are widely recognized by their biodiversity, and the provision of multiple environmental services. However, they keep facing increasing deforestation and degradation. Therefore, the management of carbon sequestration has the potential to provide benefits for the biodiversity and climate adaptation. Moreover, it allows an integral management, valuation, and conservation of forest resources. This study was carried out in montane forests in southern Ecuador. Above ground biomass carbon stock, as well as the economic value of the environmental service were estimated to justify their conservation. Using stratified random sampling, 0.1 ha plots were located along an altitudinal gradient, 2500-2900 m elevation. All individuals with diameter at breast height (DBH)  2.5 cm were identified. The measured parameters included height and diameter of the tree. Furthermore, herbarium and wood samples were collected to identify individuals by species and determine their respective density. As an additional contribution of this work, it was proposed to understand people’s perception towards the conservation of these ecosystems. Paper pencil surveys were used, focusing on the Andean bear (Tremarctos ornatus), specie at risk of extinction (VU) that lives in this area
