Explanation: Kaziranga National Park is a critical wildlife reserve located in the state of Assam, India. It is renowned for its significant population of the one-horned rhinoceros, which is a species of great conservation importance. The park is situated in the eastern part of Assam, along the banks of the Brahmaputra River, and covers an area of approximately 430 square kilometers.
Kaziranga National Park was established in 1908 as a reserve forest and was later declared a national park in 1974. It was designated as a UNESCO World Heritage Site in 1985 due to its unique biodiversity and the successful conservation efforts for the one-horned rhinoceros. The park is home to over 2,400 one-horned rhinoceros, which is the largest population of this species in the world.
The park's ecosystem is diverse, consisting of tall grasslands, dense tropical forests, and numerous water bodies. This habitat supports a wide range of wildlife, including tigers, elephants, wild water buffalo, and over 450 species of birds. The park is also known for its conservation efforts for other endangered species such as the Asiatic water buffalo and the eastern swamp deer.
Kaziranga National Park plays a crucial role in the conservation of the one-horned rhinoceros, which was once on the brink of extinction due to poaching and habitat loss. The park's conservation efforts have been successful in increasing the rhinoceros population, making it a model for wildlife conservation in India and around the world.
In contrast, the other options listed—Dispur, Silchar, and Maligaon—are urban areas in Assam that do not have significant wildlife reserves or habitats for rhinoceros. Dispur is the capital city of Assam, Silchar is a city in southern Assam, and Maligaon is a suburb of Guwahati. These areas are primarily known for their administrative, cultural, and commercial roles, rather than for wildlife conservation.
Therefore, Kaziranga National Park is the correct answer for where rhinoceros are found in Assam, as it is the primary habitat and conservation site for the one-horned rhinoceros in the region.
