The world is celebrating International Day of Biological Diversity on 22 May: the topic for 2020 is “Our solutions are in nature.”
According to the United Nations (UN), there are currently about 1.75 million species described in the world, most of which are insects. However, according to various estimates, the actual number of species ranges from 3 to 100 million. However, as a result of human activity in the world today, many plant and animal species are disappearing, as well as the number of many species is decreasing. But experts are also discovering new types of species for the science.
There are also problems with the reduction of plant and animal species and the preservation of biodiversity in Armenia. There are about 3,600 species of high-quality plants, 550 species of vertebrates and about 17,000 species of invertebrates in the small territory of our country. Under the influence of various human and natural factors, many species of the Armenian flora and fauna are considered as critically endangered, endangered, or vulnerable.
The Red Book, published in 2010, consists of two volumes, animals and invertebrates, plants and fungi. It Plants species included in the new Red Book are 452 instead of 367 in the old one, while animal species are 153 instead of 99 in the old edition plus 40 fungi species and 155 invertebrate species.But there is also good news about the discovery of new species and the increase in the populations.
According to the press release by Information-analytical Service of NAS RA, in 2019, scientists at the Armen Takhtajyan Institute of Botany at the National Academy of Sciences of the Republic of Armenia discovered the Ruppiaceae family new for the Armenian flora and the Ruppia maritima species belonging to the new Ruppia tribe in Lake Sevan from a depth of 7 meters. A new species for science, Szni Gregorian, has been found between Aghveran and Arzakan villages in the Dalar River valley in Kotayk Region. A new Tanacetum uniflorum type has been found for the Armenian flora based on previous gatherings in the floristic regions of Yerevan and Daralegis.
Zoologist Vasil Ananyan has discovered a new species for the fauna of Armenia - Aeshna juncea (sedge darner) on Amulsar Mountain in Vayots Dzor Region. On his Facebook page Vasil Ananyan posted that the new species was discovered in 2018-2019 noting: "This is a remnant of a rare and small-scale ice age in Armenia,” the zoologist posted on his Facebook page.
After a 50-year break, the leopard returned to Tavush Region. The animal was last seen in the area in the 1970s. Tavush became the fourth region in Armenia where a leopard lives.
Congratulations on International Biodiversity Day. Let's preserve nature and live in harmony with nature.
