Complete answer: The IUCN red list provides information to the public about the conservation status of the animal, plant and fungal species. It is divided into different species into seven different categories of conservation that are based on habitat range, population size, threat, etc. Antelope cervicapra is a blackbuck which is a species of deer also known as Indian antelope which is native to India and Nepal and their habitat is grassy plains or shallow forest with perennial water sources. It is considered in the least concerned status.
