One in six European mammals face extinctionPosted: 06 Jun 2007
The first assessment of all European mammals, commissioned by the European Commission, shows that nearly one in every six mammal species is now threatened with extinction. The population trends are equally alarming: a quarter (27 per cent) of all mammals has declining populations and a further 33 per cent had an unknown trend. Only 8 per cent were identified as increasing, including the European bison, thanks to successful conservation measures.
Europe is now home to the world�s most threatened cat species, the Iberian Lynx, and the world�s most threatened seal, the Mediterranean Monk Seal, both classified as Critically Endangered.

Environment Commissioner Stavros Dimas said: �The results of the report highlight the challenge we currently face to halt the loss of biodiversity by 2010, as European governments have promised. It is clear that the full implementation of the Habitats Directive, which covers nearly all mammals found threatened in this assessment, is of utmost importance to protect Europe's species".
The assessment was carried out by the World Conservation Union (IUCN, whose Director-General Julia Marton-Lef�vre said that while it proves that many European mammals are declining at an alarming rate "we still have the power to reverse that trend, as the case of the European bison which was brought back from extinction clearly shows.�
Europe contains a rich diversity of mammals ranging from the small and rarely seen nocturnal shrews and voles to the elusive brown bear. But the results of the European Mammal Assessment are clear: while some 15 per cent, or almost one sixth, of mammals are threatened in Europe, the situation of marine mammals is even bleaker. Some 22 of these are classified as threatened with extinction. The true number is likely to be even higher, as almost 44 per cent were classified as Data Deficient due to missing information. By comparison, 13 per cent of European birds are threatened.
Lost habitat
The main threats to European mammals are habitat degradation and loss such as deforestation or wetland drainage, followed by pollution and over-harvesting. For marine species, pollution and accidental mortality from fisheries by-catch or ship collisions are the main risks. These threats are most severe in the enclosed seas of the Baltic, Mediterranean and Black Sea.

Within the European Union, six species have been classified as Critically Endangered. The most threatened category includes the Arctic fox and the European mink, which both have very small and declining populations. Only 150 Iberian Lynx survive today and the Mediterranean monk seal population has decreased to between 350-450 individuals.
Europe is one of the best studied regions of the world, but no overall view of the conservation status of mammals across the continent had been compiled. To fill that gap, the European Union commissioned IUCN to assess all mammals of continental Europe against the IUCN Red List criteria in order to identify Europe�s most threatened mammals and help set conservation priorities.
The assessment shows that Europe�s mountains and the Balkan Peninsula are home to the greatest diversity of species. This wealth of biodiversity forms an arc which extends from the Pyrenees through the Alps towards the Carpathians and Rhodopes in south-eastern Europe. The greatest concentration of threatened species was found in Bulgaria.
Ibex success
The European bison was brought to the brink of extinction during the early 20th century when the last individuals were saved in zoos. As a result of reintroductions and introductions, there are now some 1,800 individuals occurring in free-ranging and semi-free herds in Poland, Lithuania, Belarus, Russian Federation, Ukraine, and Slovakia.
The Alpine Ibex, another European endemic, was brought close to extinction in the 19th century by intensive hunting and was found only in the Gran Paradiso National Park in Italy. This species is now classified as least concern due to extensive conservation efforts and re-introductions.

To reverse the decline of Europe�s mammals, the study recommends urgent implementation of the EU�s nature conservation policies, to develop species action plans and integrate nature conservation into the EU�s land use policies.
�Today is World Biodiversity Day � a unique chance to celebrate the diversity of life on Earth and to remember humans� fragile place within this complex web. As we celebrate this day we have to remember that our actions have brought many species to the brink of extinction, however we must also know that we have the power and opportunity to reverse this situation,� said Julia Marton-Lef�vre.
