As a result of the effects of the ENSO (2010 – 2011), in Colombia, among other initiatives, the project to generate technical inputs for the delimitation of strategic ecosystems of moors and wetlands was undertaken. Some of these ecosystems are related to groundwater by exchanging inputs in aquifer recharge, transit or discharge zones. In rainy seasons, wetlands contribute to the regulation of flows and in times of drought they are maintained thanks to the water that reaches them from the subsoil. Some human actions on the ground or aquifers put their functions and services and those of related ecosystems at risk. Within the framework of agreement No. 15-13-014-068 CE between the Alexander von Humboldt Biological Resources Research Institute and the University of Antioquia, the interconnection between wetlands and groundwater in Colombia was made clear. From the available information, fourteen wetlands related to hydrogeological systems were identified, for a first characterization of ecosystem services based on cartographic overlay exercises and on the status and trend of the main factors of change. This study identifies the state and trend of both ecosystem services and change factors, highlighting the most important aspects found in the fourteen wetlands analyzed. It is important to highlight that efforts must be joined to integrate and make coherent the formulation and application of management and protection measures from the Environmental Plans referring to water and its biodiversity, including both wetlands and aquifers.
