Difference between endangered and vulnerable species

The numbers of vulnerable, endangered, and critically endangered species are constantly rising despite the global protective, as well as conservative measures. Ongoing pace of loss of species diversity is attributed to the host of reasons. For your better insight, I am going to explain the difference between vulnerable and endangered species as per the red data book of IUCN.

Role of Red Data Book

Red data book is systematic documentation of the various species of plants, animals, and other living organisms, occurring on the planet. It is being regularly compiled under the aegis of IUCN.

The genuine purpose of Red Data Book is to make available up-to date information about the various species according to theirs degree of vulnerability. It categories species in the form of vulnerable, endangered, critically endangered, and extinct species based on determined criterion.

Every nation has it’s own red data book to supervise and manage the state of species within their territory.

Vulnerable species

As I mentioned earlier that the base of classification is the degree of vulnerability of that specific species in the respective region. In layman’s term, when there is fifty percent of reduction is noticed in the population of a particular species over a decade of time, it is called the vulnerable species.

Examples of vulnerable species in India are Indian rhinoceros, red panda, himalayan take etc.

Endangered species

Endangered species is called when there is seventy percent of ¬†reduction of particular species population over a decade of time. It’s degree of vulnerability is more than that of the vulnerable species. So, more serious efforts demands attention here.

For example, Bengal tiger, Asiatic lion, black buck are classified as endangered species.

Critically endangered

Compare to other two categories, critically endangered is the most serious one. When there is more than ninty percent of population reduction is noticed of any particular species over a decade of time, it is called critically endangered species.

Examples, Gharial, Indian vultures, Siberian crane, great Indian bustard, are some of names of critically endangered species.

Extinct species

This is the last category used for species totally vanished over a certain period of time. Unfortunately, in the world, the numbers of extinct species are not declining as per the conservational measures.

In India, the process of conservation has been started since the colonial age. And, since, independence, the measures has been accelerated by making punitive laws and establishment of sanctuaries, national park, and biospheres, for conservational, as well as protective purposes.
