As of 2009, ECNC worked with a number of other organizations under the name ‘ECNC Group’. The members of the ECNC Group were ECNC, the Coastal & Marine Union (EUCC) and Centro Mediterráneo EUCC. The Large Herbivore Foundation joined the ECNC Group in July 2010. EuroNatur, the NatureBureau and EECONET Action Fund were observers. The ECNC Group consisted of two units: 'Biodiversity and Nature' (ECNC) and 'Coastal and Marine' (EUCC).
