With this point of view, it was proposed an ecological assessment of an urban wetland called “Libelula”, injured by neighboring community. In this project, the Carlson´s Trophic State Index was employed and the inspection of the relationships between living species and physicochemical parameters by the application of PCA methodology was also done. Results show that eutrophic state has been reached generating an increase of certain phytoplankton, zooplankton and macrophytes species, which have been associated with nutrient and organic matter enriched water ecosystems. The change of bathymetry of Libelula´s Wetland in time was studied with GIS and UAV techniques showing a great negative impact principally because of residential activities which lead to lose important ecosystem services.
