Red List reports
These summary statistics and analyses are based on the European mammals dataset published in May 2007.
Terrestrial mammal biodiversity is greatest in southeastern Europe (the Balkan Peninsula, Hungary, and Romania) and in the mountainous regions of Mediterranean and temperate Europe. Habitat loss and degradation is the greatest threat to terrestrial mammals in Europe. Human disturbance, pollution, accidental mortality (e.g., secondary poisoning, vehicle collisions), overexploitation and invasive species are also important threats. The main threats to marine mammals are accidental mortality (e.g. fisheries bycatch), pollution, and overexploitation.
