Abstract
The conservation of harbor porpoises (Phocoena phocoena)
appears to be failing in Europe. There are particular concerns about this
species in the Baltic Proper, Black, and Mediterranean Seas, as well as in the
Northeast Atlantic, including the Iberian population, off the Spanish and
Portuguese coasts. The Baltic Proper porpoise is “critically endangered,” with
a population only in the low hundreds, and the Scientific Committee of the
International Whaling Commission has repeatedly called for action to ensure its
survival. In 2020, the Committee issued a series of recommendations relating to
it and the Iberian population. Similarly, the Black Sea harbor porpoise, Phocoena phocoena ssp. relicta, is
classified by the IUCN as endangered. Another population which may be
genetically distinct is the West Greenland harbor porpoise, which is hunted
without quotas or close seasons. European cetaceans and their habitats are
covered by a number of international and regional conventions and agreements
and, under European Union law, are “highly protected.” In practice, however,
these legal protections have failed to generate effective conservation. For
example, Special Areas of Conservation (SACs) are required for them and,
although sites have been designated in some marine areas/countries, in the
absence of appropriate management plans, SACs cannot be expected to help
improve the harbor porpoise's conservation status. Compared to many other
species, porpoises are relatively long-lived with low reproductive capacity and
only poor public recognition. Conservation and management efforts are caught up
in a complicated nexus of interactions involving a web of commitments under
international conventions and agreements, European environmental laws, and
European fisheries policy. However, public disinterest, lack of political will
to implement conservation measures, and complicated fishing-related issues
hinder any real progress. More positively, recent advice from the International
Council for the Exploration of the Seas (ICES) provides a new scientific
foundation for conservation action to address fisheries bycatch in the Baltic
Proper harbor porpoise population. Populations of other porpoise species
(family Phocoenidae) are also threatened, most notably the global population of
the critically endangered vaquita, or Gulf of California porpoise (Phocoena sinus). The
common threats and factors affecting porpoise populations are discussed and
recommendations offered.
