What categories does the IUCN use to designate the status of species and higher taxa?

Summary Introduction

To review:

The categories used by IUCN to assign the status of species and higher taxa.

Introduction:

IUCN stands for “International Union for Conservation of Nature,” which is a nonprofit organization (NGO) that helps to determine the status of the living organisms. The IUCN sponsors scientific researches and organizes conferences to discuss environmental challenges. It was formed in 1948 and its headquarter is located in Switzerland. IUCN also approaches to provide practical solutions to the environmental problems, besides holding conferences and scientific researches.

Explanation

IUCN maintains a Red list of threatened Species, which includes species that are on the verge of extinction. These species are termed as endangered or threatened. IUCN discusses the solutions that would help in preserving the endangered species. The Red list contain many categories to organize the species and higher taxa according to their status in the wild. The categories provided by IUCN are as follows:

1. Least concern: The species of animals that do not face any chance of extinction in the near future, falls under this category. For example, giraffe, koala, poison dart frog, and others in India.

2. Near threatened: The species of animals under this category might face the chances of extinction in the near future if their breeding rate falls down. For example, great Indian bustard, Himalayan quail, and others fall under the category of near threatened.

3. Vulnerable: The species might face extinction in the near future if the conditions that threaten their survival do not improve, for example, black buck and yalk...
