The environmental NGOs BirdLife Malta, Din l-Art Helwa, Flimkien Ghal Ambjent Ahjar, Friends of the Earth Malta, Gaia Foundation, Light Pollution Awareness Group, Nature Trust (Malta) and Ramblers Association condemned the vandal attacks at Dwejra Heritage Park in Gozo where graffiti was sprayed on information boards and on rocks in the area.

Dwejra is a designated Natura 2000 site and a possible candidate as a World heritage site due to its paleontological, geological, ecological, ornithological, marine ecology and scenic importance. It is also one of the main tourist sites on the Maltese islands.
