Last century they lived only in captivity, but European bison steadily make a comeback in the wild. It is one of the 25 endangered species worldwide that according to the IUCN nature organization, things are going a lot better. The so-called bison population is also growing in the Netherlands.
IUCN today released an update of the red list of endangered plant and animal species. The report states that another 31 species are now officially considered extinct. The number of endangered species has increased again this year according to the nature organisation. There are now 128,918 species of plants and animals on the red list. Of these, 35,765 are threatened with extinction.
The revival of Europes largest land mammal, the bison or bison, was also possible only through a comprehensive cooperation project. In recent years, the grazers have been deployed in various places in Europe. As since 2007 in the Netherlands.
“ This news confirms that smart action allows us to give animal species a new chance – and that it works,” says Jan Wolleswinkel of Stichting Wisent op de Veluwe. There are currently six bison grazing in a closed nature park on the Veluwe.
“ Only bulls are born with us, so they have to be put out in the end,” explains Wolleswinkel. There is plenty of exchange within Europe to give the animals the best chance. “We have an animal running here from Poland and recently one of our bulls has been moved to Spain.” An adult bull can weigh up to 800 pounds.
Two years ago there were about seventy bison in the Netherlands. That number has now increased and these bison have been deployed in more and more natural parks. “You have to keep 50 meters away and if they have young, you should be even more careful,” says Wolleswinkel. Throughout Europe, the population has risen from around the 1800 at the beginning of this century to over 6200 last year.
For example, the opposite happens with freshwater dolphins, reports IUCN. All species of these aquatic mammals are now under threat. Until recently, there was not enough data about the Amazon dolphin, but now it is clear according to the nature organization that this is going badly. Due to overfishing and the construction of dams, this dolphin is also included on the red list.
In this graph you can see the increase in the number of animals and plants on the red list and the proportion that is threatened with extinction:
Not only animal species have it heavy according to IUCN. Almost a third of all oak species (113 out of 430) are now threatened with extinction. Also three types of macademia plants are on the red list. It is about the wild variant of the plants on which the nuts grow.
For more than thirty species, the canvas has fallen definitively according to the nature organisation. Three of them are Central American frog species. And in the Philippines, fifteen freshwater fish species are extinct in Lake Lanao. Two other species are included in the category possibly extinct.
This is also the case for the carcharhinus obsolerus, or the lost shark. As far as we know, this fish was last seen in the South China Sea in 1934. According to IUCN, due to overfishing, it is highly unlikely that the species of shark still exists.
