Explanations:The one-horned rhinoceros, scientifically known as Rhinoceros unicornis, is a large mammal that is native to the Indian subcontinent. This species is one of the five extant rhinoceros species and is found primarily in the northeastern states of India, with Assam being the most significant habitat. The one-horned rhinoceros is critically endangered, and its conservation is a priority for wildlife authorities in India.
Assam is home to several national parks and wildlife sanctuaries that provide a suitable habitat for the one-horned rhinoceros. The Kaziranga National Park, located in Assam, is particularly renowned for its rhinoceros population. This park is a UNESCO World Heritage Site and is known for its successful conservation efforts. The Manas National Park, also in Assam, is another important habitat for the species.
The one-horned rhinoceros requires specific environmental conditions to thrive, including large areas of grassland and wetlands. These conditions are found in abundance in Assam, which is why the state is the primary habitat for the species. The rhinoceroses in Assam are protected under the Wildlife Protection Act of 1972, which prohibits hunting and poaching of the species.
While other northeastern states like Arunachal Pradesh, Tripura, and Mizoram are part of the same region, they do not have the same level of habitat suitability or conservation efforts for the one-horned rhinoceros. Therefore, Assam is the correct answer to the question regarding the state where the one-horned rhinoceros is found.
