Large populations of eight marine mammal species, including several cetacean species, were discovered, supported by a permanent frontal system concentrating vast populations of zooplankton and other food sources. The presence of these spectacular mammals in such a heavily used area surprised the public and the scientific community alike. The confluence of this discovery, and heightened public awareness about a spate of marine mam- mal strandings resulting from disease and by-catch in the drift net fishery, has led to a drive to protect this newly discovered special feature. The governments of Italy, France, and Monaco made an unprecedented move to protect this high seas area by declaring it a marine mammal sanctuary called “Pelagos”. The drive to protect the area was led by a few environmental champions, who recognized both the threats and the opportuni- ties to promote large-scale marine conservation. These champions include Prince Rainier III, who mobilized Monaco and led the neighboring states into multilateral agreements, top diplomats, legal scholars and the founder of Tethys, a highly regarded Italian Non-Governmental Organization (NGO). The opportunity to establish a tri-national marine protected area was, para- doxically, created by the lack of mechanisms for protecting the high seas, since Mediterranean countries have not yet declared 200-mile Exclusive Economic Zones (EEZs), and no legal framework existed for management of marine areas outside of the 12-mile territorial seas. The responsibility to successfully implement the Pelagos Sanctuary still rests on the three governments, but the conservation effort’s success will likely rest on a committed drive by civil society to keep pressure on the public sector to live up to its commitments.
