Abstract

Ecosystem services are the benefits that societies obtain from ecosystems. This concept allows making more explicit the interdependence of human well-being and the maintenance of the proper functioning of ecosystems. Regarding their classification, the Millennium Ecosystem Assessment proposal (MEA) is used, which classifies ecosystem services into four groups; Provision, support, cultural and regulation supplies, the latter being non-consumptive functions that generate ecosystem conditions that do not undergo transformation or manufacturing processes. This is why there was a need to examine and identify the ecosystem services (IES) provided by the tree and dioecious species, Morella pavonis to the town of Chapisca, located 60 km from Arica through the Lluta valley in the region from Arica and Parinacota. In the first instance, the vegetative islands of Morella pavonis and the associated vegetation cover were identified in situ; In a second instance, using the international geographic information system (QGIS), the regulatory ecosystem services provided by the Morella pavonis species to the Arica and Parinacota region were determined. As a result of the study, an SER was directly related to the ambient temperature. Over time the temperature has been increasing, an environmental condition inversely proportional to the relative abundance of the tree species, decreasing in around 62% its surface in the ecological assembly. It is proposed to review its current state of conservation and generate a new state of the art for the protection and conservation of the species.
