9 classification of Red Data Book we need to know in 2021 |

What is Red Data Book?

IUCN (International Union for Conservation of Nature) has been on a global scale for the past 50 years in collaboration with the Global Species Program and the Species Survival Commission. exposes and promotes their protection. The publication of the Red Data Book was started in order to delineate the status of castes and the measures needed to protect them. The IUCN, in conjunction with the Global Species Program and Species Survival Totals, provides unbiased and science-based information on the threatened status of global biodiversity. Plants, fungi and animals are assessed/marked on the IUCN Red List. These are the factors that hold the genetic diversity of plants, fungi and animals and keep the ecosystem functioning.

IUCN classification

The species are placed in a total of nine categories according to their status on the IUCN Red List.
This assessment is done on the basis of decline in the number of species, their position in the geographical area.
The categories prescribed by the IUCN are as follows:

1. extinct

Species of which no members are alive and their numbers have been completely eliminated in all habitats of the world and it will be known with confidence or that the species has completely disappeared is called extinct species. Over a period of time it is estimated whether a species of a species is alive on it, if they do not get the presence of time at that time, they are placed in the extinct category.

2. Extinct in the Wild

Species in which all species have lost their lineage and many species are kept in zoos or other artificial habitats apart from their natural habitat.

3. Critically Endangered

When species are at serious risk of extinction from forests, they are classified as critically endangered, if a population reduction of more than 90% is recorded in 10 years, they are classified as critically endangered. is kept in. If the population of Hindi species is less than 250 and there is a reduction of 25% in 3 years, then they are classified as critically endangered. If there are only 50 or less mature members, it is classified as critically endangered. A critically endangered species is a category very close to extinction. Species in this range have a 50% chance of extinction.

4. Endangered

Such species are in danger of extinction from the forests. If a population reduction of 70% is observed or recorded in 10 years, the species is classified as endangered. Only 250 slept with the lowest mature member count. Under this category 20% of species are expected to become extinct in 20 years. If the population of the species is less than 2500 and there is a decrease of 20% within 5 years, it is placed in this category. Organisms that fall under this category are at high risk of extinction.

5. Weak

Species that are likely to be endangered by forests. A decrease of more than 50% in the number of species has been recorded in 10 years. The species has a population of less than 10,000 and is declining by 10% within 10 years. Only 6 if 1000 or less mature members are placed in this category. There is a risk of extinction in this category.

6. Near Danger

The species is likely to be threatened in the near future.

7. Least Worry

Species in this category are at very low risk. This species is found in a wide area. Species in this category are not threatened in the future.

8. Lack of Data

Due to the paucity of data about the species, its conservation status and crisis cannot be predicted. The species threatened with extinction cannot be clicked due to lack of sufficient data, directly or indirectly. India is unable to estimate the wide area and sufficient number of species.

9. Not rated

The species’ protected status has not been assessed on the IUCN’s conservation criteria.
