The Ministry of the Environment, Climate and Sustainable Development (MECDD) decided in 2008 to entrust the coordination of the COBIMO-LUX scheme to the natur&ëmwelt a.s.b.l. This institution brings together a pool of volunteering field ornithologists. The Common Bird Monitoring Scheme in Luxembourg (COBIMO-LUX) has been developed to evaluate the long-term population trends of common bird species by means of standardized field methods for data collection.
