The international Union for conservation of nature (IUCN) published a new version of the red book, which this time fell five of the six species of American trees, almost completely destroyed by beetles»saboteurs» from China and Russia, and many species of African antelope have become endangered because of poaching and population growth Africa.

«Poplar trees are a Central part of plant ecosystems in the US and they have become very popular ornamental plants – the streets and gardens of many cities now adorn millions of these trees. Over 80% of poplars may disappear in the near future, and today we are actively trying to figure out how to slow down their disappearance,» said Murphy, Westwood (Westwood Murphy), one of the Botanical specialists of the IUCN.

The so-called emerald buprestids (Agrilus planipennis) are widely distributed in the East of Russia and China where these insects are striking the old and diseased ash trees without causing serious problems for healthy trees and other vegetation. While unclear how they entered the territory of North America in 2002, and since then they have rapidly spread in real whitewashed ash forests in Canada and the United States, literally mowing down them 10 years after the appearance of the first specimens of jewel beetles in different forest areas.

Because of these beetles, five of the six most common species of poplar in North America got a new version of the red book as species which are today in a critical condition. Another view of poplars fell into the category of species whose survival is under threat.

The total number of poplars at the moment is about nine billion trees, most of which may disappear in the next 10 years as a result of the further spread of the beetles-the»saboteurs». This will not only lead to large-scale reconstructions of the ecosystems, but will also deprive the economy of the USA and Canada source of wood for furniture, baseball bats, Golf clubs and tennis rackets.

In addition to poplars, extinction and today threatens another common group of living beings, the African antelope. Over the past 15 years, according to the compilers of the red book, the number of the most common types of these mammals declined sharply, falling in some cases to 50-55%.

Due to this, several antelope were transferred from the category of animals that are not threatened by danger, in the number of species under threat of extinction. In their number were Western Eland (Tragelaphus derbianus), the largest antelope of Land, marsh and mountain goat (Redunca fulvorufula), Heuglin Gazelle (Eudorcas tilonura), litchi Waterbuck (Kobus leche) and the antelope-deer (Pelea capreolus), is a living symbol of sportswear and shoes Reebok.

The reasons for the reduction in numbers, as noted by the ecologists, in principle, are common to all of these antelope poaching, generated by the political instability in South and Central Africa, as well as competition for living space and resources with livestock.

Some other animals are already extinct – like the Book says, unique bats Pipistrellus murrayi, who lived on Christmas island, completely disappeared from the face of the Earth. The reason for their extinction is not yet clear, but scientists speculate that they were destroyed invasive species of ants, feeding on the same insects which were eaten by these bats are mammals. This is the third species from this island disappeared over the last century.

The only bright spot in the new version of the red book snow leopards (Panthera uncia) — the number of these mountain cats increased slightly over the past 15 years, which has allowed ecologists to translate them from the number of animals threatened with extinction, the list of vulnerable species.

Currently, the red book contains approximately 87 thousand species of animals and plants, about 25 thousands of which are now threatened with extinction. At the time of writing books about 860 species of flora and fauna has completely disappeared from the face of the Earth, and another 68 species present only in zoos and nurseries of plants, and about five thousand is in critical condition.
