A 40% decline in giraffe populations has been observed in Africa over the past 30 years, says a report by the International Union for the Conservation of Nature (IUCN), which now ranks the animal in the list of species “Vulnerable” and threatened with extinction.
On the occasion of the International Conference on Biodiversity in Mexico, the updated list of the list of the International Union for the Conservation of Nature (IUCN) a reference organization to monitor the status of species in the world, revealed: of the 742 bird species newly assessed by IUCN, 11% are threatened with extinction. Giraffes are also entering the category of “vulnerable” species: their numbers have dropped from 36 to 40% in 30 years.
Out of 9 subspecies in 21 countries, three are doing well, one is stable, but the other five are in sharp decline, according to the report.
According to scientists, our world is experiencing a new mass extinction, the sixth only in 500 million years: species disappear 1,000 to 10,000 times faster than a century ago.
Species, just discovered, and already extinct or endangered
The list includes to date 85,604 animal and plant species (only a fraction of the total), of which 24,307 are endangered.
In recent years, 742 bird species have been identified (totaling 11,121). But 11% of them are already considered “threatened”, among which 13 are already extinct, especially in islands colonized by invasive plants. “Many species disappear before we can describe them,” says Inger Andersen, Director General of IUCN. The importation of new predators, including snakes, has caused the disappearance of birds.
Among the bird species listed in the red list, more than one in ten could disappear in the coming years: the parrot jaco (very popular with amateurs because among the best speakers), or gray parrot of Gabon, known for its ability to reproduce human language, sees its situation deteriorate. Originally from Central Africa, its population has dropped by nearly 99% in some areas. The situation is even worse in Asia, where illegal harvest of birds for trade is emptying forests: the colorful colorful Forsten lorikeet, endemic to Indonesia, and the yellow-headed bulbul are now considered vulnerable.
“Many species are disappearing even before we have had the time to describe them,” says IUCN Director Inger Andersen: “This update shows that this extinction may be more extensive than we imagined. . “
“The States gathered in Cancun must increase their efforts to protect the biodiversity of our planet, he adds: not just for biodiversity itself but also for people, including food security and sustainable development. “
The Corsican nuthatch and the Atlantic puffin endangered
“As our knowledge increases, so do our concerns,” says Ian Burfield of BirdLife International. Intensive agriculture, deforestation, invasive species and other threats such as species trafficking still lead many species to extinction. “

And France is also a victim of this decline in animal species: 14 species are in danger of extinction, warns the League for the Protection of Birds (LPO). Ranger of Reunion, black petrel of Bourbon, puffin of the Balearic Islands, lori diadem, martin-fisherman of the Marquesas … could soon be only memories. The Atlantic puffin, the Corsican nuthatch or the turtledove are classified as “vulnerable”.
