Migratory species in an increasingly precarious situation, warns a UN report. Among the species listed by the 1979 Bonn Convention on the Conservation of Migratory Species of Wild Animals, one in five is threatened with extinction and 44% are seeing their population decline.
“The phenomenon of migration itself is in danger, because there are barriers and the habitats these animals need may be under pressure,” Amy Fraenkel, executive secretary of the Convention, told AFP. The threats to these animals are directly linked to human activity: loss, degradation or fragmentation of habitats mainly due to intensive agriculture.
