Ecological Assessment by Physical Chemical and Biological Interactions Analysis in Trophic State of Libelula´s Wetland – Bogotá - Colombia

Liliana Ardila, Steven Mora, and Ruth Flórez

Abstract—Due to the serious problems that affect aquatic ecosystems around the world, human survival has been put in risk. _Colombia has been considered to have a great hydric wealth but its people are suffering of water supply limitation and the reception of less quality water due to inappropriate use of water resources. For this reason, many actions have been taken to keep in observation lotic and lentic water body’s performance, taking in count all nature and human contributions which may disrupt to greater of lesser degree the water quality and viability of aquatic species. Therefore, this permanent inspection has helped in the proposal of solutions to avoid or alleviate the harm done in water bodies and recover them to guarantee the typical functioning of hydric ecosystem.
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.

Index Terms—Ecological assessment, trophic state index, water quality, wetlands, limnology.
