Application of the ecosystem approach for the management of Eucalyptus globulus, an invasive non-native species, in Quito ? Ecuador

Invasive non-native species (INNS) are one of the main factors responsible for environmental change and their negative impacts on biodiversity and ecosystems (ecosystem services) have been generating severe socioeconomic problems around the world. In addition, among the most challenging and poorly s...

Application of the ecosystem approach for the management of Eucalyptus globulus, an invasive non-native species, in Quito ? Ecuador
description Invasive non-native species (INNS) are one of the main factors responsible for environmental change and their negative impacts on biodiversity and ecosystems (ecosystem services) have been generating severe socioeconomic problems around the world. In addition, among the most challenging and poorly studied INNS are the invasive non-native trees (INNT). Such is the case of Eucalyptus globulus, an INNT widely introduced for commercial purposes and whose negative impacts have gone unnoticed. In Ecuador E. globulus have become an integral part of the ecosystem and landscape due to the benefits or ecosystem services (ES) (e.g. recreation, pure air and protection against volcanic eruptions) that local population is receiving from Eucalypt invasions, to the extent that are considered native forest. The aim of this research is to develop a strategy for the management of Eucalyptus globulus in Quito ? Ecuador, by adopting the ecosystem approach. In order to achieve this aim an outline management plan was proposed which was elaborated by carrying out an empirical spatial analysis. For this purpose satellite images and maps of Quito were obtained from Google Earth?.
