It’s hard enough for a wild animal to survive in one environment. Let’s think about migrants, who have to cross so many with their strength reduced to nothing by the long journey.
The first report on migratory species
The first “State of the World’s Migratory Species” report on migratory species describes a worrying situation. 44% of those surveyed by the study (1,189 in total, but there are at least 3 thousand others outside the monitoring) are in decline. 22% are threatened with extinction. Even more than in the sky, the situation is difficult at sea.
Fish at risk of extinction
In fact, 97% of the fish species listed in the report are threatened with extinction. At risk are sharks, rays and sturgeons in particular: since the 1970s their numbers have reduced by 90%. Over the past 30 years, 70 species listed in the report have approached the threshold of extinction: the steppe eagle, the Egyptian vulture and the wild camel. However, 14 species have seen their situation improve: blue whale, humpback whale, white-tailed eagle ray and black-masked spoonbill.
The cause is hunting and fishing
The main cause of the decline of migratory species is direct hunting or fishing by humans. Immediately after comes the degradation of habitats, which for those who travel can be numerous. “Migratory species need a variety of habitats at different stages of their life cycle. They travel sometimes thousands of kilometers to reach these places. They face enormous challenges and threats both along the way and at their destinations, where they feed and reproduce,” explains Amy Fraenkel, secretary of the United Nations Convention on the Conservation of Migratory Species (CMS). The first report is made public today at the CMS conference in Samarkand, Uzbekistan.
The end of the steppe antelope
Precisely in this Central Asian country one of the most emblematic stories is recorded: that of the saiga antelope or steppe antelope, recognizable by its nose similar to a short trunk. Having come close to extinction, its numbers began to rise again over the years. Today, however, drought is once again affecting its population. A sign that where it is not the action of human beings that threatens a species, climate change is coming to complicate the situation.
