Concept notes: Assam, a state in northeastern India, is home to several endangered species. These include the one-horned rhinoceros, Royal Bengal tigers, and the golden langur. Each of these species faces threats due to habitat loss, poaching, and other human activities, making their conservation a critical issue.
Explanation: Assam, a state in northeastern India, is renowned for its rich biodiversity and is home to several endangered species. The conservation status of these species is a critical issue due to various threats such as habitat loss, poaching, and human-wildlife conflict.
The one-horned rhinoceros (Rhinoceros unicornis) is one of the most iconic and endangered species found in Assam. It is primarily concentrated in the Kaziranga National Park, which is a UNESCO World Heritage Site. The rhinoceros faces significant threats from poaching, as its horn is highly valued in illegal wildlife trade. Additionally, habitat loss due to human encroachment and agricultural expansion poses a serious threat to the species.
The Royal Bengal tiger (Panthera tigris tigris) is another critically endangered species found in Assam. It is a flagship species for conservation efforts in the state, particularly in the Manas National Park and other protected areas. Tigers are threatened by poaching for their skin and body parts, as well as habitat loss due to deforestation and human activities. The loss of prey base and human-tiger conflict also contribute to the decline of tiger populations in Assam.
The golden langur (Trachypithecus geei) is a lesser-known but equally endangered primate species found in Assam. It is primarily found in the Manas National Park and the neighboring areas. The golden langur is threatened by habitat loss due to deforestation and fragmentation, which disrupts its natural habitat and reduces its population. Conservation efforts for the golden langur are crucial to maintain the biodiversity of the region.
All these species are listed as endangered under the International Union for Conservation of Nature (IUCN) Red List and are protected under the Wildlife Protection Act of India. The conservation of these species is not only important for maintaining the ecological balance but also for preserving the rich biodiversity of Assam.
In conclusion, the correct answer is (D) All of these, as it encompasses all the endangered species mentioned: the one-horned rhinoceros, Royal Bengal tigers, and the golden langur. Each of these species plays a vital role in the ecosystem of Assam and requires concerted conservation efforts to ensure their survival. Understanding the conservation status and threats faced by these species is crucial for students studying Assam's geography and wildlife.
