Explanations:Endangered species are those whose populations are at risk of extinction due to various factors such as habitat loss, poaching, and climate change. In the context of Assam, several species are listed as endangered, and it is important to understand the conservation status of these species to appreciate the biodiversity and the efforts required to protect them.
The one-horned rhinoceros (Rhinoceros unicornis) is a large mammal found in the grasslands and forests of Assam. It is listed as Vulnerable on the IUCN Red List, which means it is facing a high risk of extinction in the wild. The population of the one-horned rhinoceros has been declining due to habitat loss and poaching for its horn, which is highly valued in traditional medicine.
The Royal Bengal tiger (Panthera tigris tigris) is another iconic species found in Assam. It is listed as Endangered on the IUCN Red List, indicating a very high risk of extinction in the wild. The Royal Bengal tiger faces threats such as habitat loss, poaching for its skin and body parts, and human-wildlife conflict. Conservation efforts, such as the establishment of protected areas and anti-poaching measures, are crucial to protect this species.
The golden langur (Trachypithecus geei) is a primate species found in Assam and parts of neighboring Bhutan. It is listed as Endangered on the IUCN Red List, indicating a very high risk of extinction in the wild. The golden langur faces threats such as habitat loss due to deforestation and fragmentation, and poaching for the pet trade. Conservation efforts, such as habitat protection and community-based conservation initiatives, are essential to protect this species.
Therefore, all of these species—the one-horned rhinoceros, the Royal Bengal tiger, and the golden langur—are endangered and found in Assam. The correct answer is "D) All of these," as it correctly identifies the conservation status of multiple species in the region. Understanding the conservation status of these species is crucial for effective wildlife management and biodiversity conservation efforts in Assam.
