Red Data Book
Scientist thought to create a record of all the species present globally so to know the status of the conservation problem.
Scientist planned to structure a book named "Red data Book" which also imparts information to the public.
Let's get introduced to Red Data Book.
Red Data Book is structured and issued by the IUCN (International Union for the Conservation of Nature and Natural Resources).
In this book, information coverage ranges from endangered species to less remarkable organisms facing extinction.
All the species present throughout the globe are listed in the Red Data book.
This book has assessment of more than 18,000 species of which 11,000 are threatened.
Let us now see the categories of list based on which the species are classified .
All the species are categorized under 8 different list.
When the last survived individual of a species is died then the species is known to be Extinct (EX).
Dodo and West African Black Rhinoceros belong to the list extinct.
When the species extinct in the normal habitat but few individuals of the species survived in the captivity then the species belong to the list, Extinct in the Wild (EW)
Black Soft Shell turtle and Spix's Macaw belong the list Extinct in the Wild (EW).
When the species is at high risk of extinction in the wild, it comes under the list Critically Endangered (CR)
Amur Leopard and Sumatran Tiger belongs to list Critically Endangered (CR).
When the species are very likely to become extinct in the near future, then it comes under the list Endangered (EN) species
Blue whale and Bengal Tiger belongs to the list Endangered (EN) species.
When the species are likely to become endangered in the near future, it is known as Vulnerable (VU) species.
Hippopotamus and Polar beer are categorized as vulnerable species.
Few species that are considered threatened with extinction in the near future, are listed as Near-Threatened (NT) species.
Jaguar and White Rhino are listed as Near-Threatened Species.
Few species do not qualify as threatened, near threatened, or conservation dependent, which indicates it as Least Concern (LC) species.
Brown bear and Gray whale are listed as Least concern species.
Some species have insufficient information for a proper assessment of conservation status to be made, which is known as Data Deficient (DD) species.
False killer whale and Somali elephant shrew comes under the list data deficient species.
The species which has not been evaluated by the International Union for Conservation of Nature are listed as Not Evaluated (NE) species.
Sugar ant and milk fish are listed as not evaluated species.
Let us now see the number of contribution to the Red list by India.
44 plant species were listed as critically endangered species. eg- Berberies nilghirensis
113 plant species were listed as Endangered species. Eg-Bentinckia nicobarica
87 plant species were listed as vulnerable species. Eg-Cupressus cashmeriana
18 animal species were listed as critically endangered species. Eg- Pigmy hog
54 animal species were listed as endangered species. Eg-Red Panda
143 animal species were listed as vulnerable species. Eg- Black Buck
Red Data Book is structured and issued by the IUCN which includes all the species that are globally present.
The red data book categorize the species into 8 different list.
The list include extinct, extinct in the wild, critically endangered, endangered, vulnerable, near threatened , least concern, data deficient and not evaluated species.
India has also contributed in a large number to the Red Data book.
