Consider the following statements :
1. Biodiversity hotspots are located only in tropical regions.
2. India has four biodiversity hotspots i.e., Eastern Himalayas, Western Himalayas, Western Ghats and Andaman and Nicobar Islands.
Which of the statements given above is/are correct?
Correct Answer: Option D
Explanation
1. Statement 1: Biodiversity hotspots are regions characterized by exceptional levels of plant endemism and serious levels of habitat loss. While many hotspots are located in tropical regions due to favourable conditions for speciation, they are not located only in the tropics. Examples of non-tropical hotspots include the Mediterranean Basin, California Floristic Province, and the Mountains of Central Asia. Therefore, statement 1 is incorrect.
2. Statement 2: India currently has four designated biodiversity hotspots according to Conservation International: the Himalayas (covering the entire Indian Himalayan region, including both Eastern and parts of Western Himalayas in a broader sense), the Western Ghats, the Indo-Burma region (includes parts of North-Eastern India), and Sundaland (includes the Andaman and Nicobar Islands). The statement lists Eastern Himalayas, Western Himalayas, Western Ghats, and Andaman and Nicobar Islands. While these regions contain hotspot areas, the official designation 'Himalayas' covers both Eastern and Western parts, and North-East India falls under Indo-Burma. Listing Western Himalayas as a separate hotspot distinct from 'Himalayas' is incorrect according to the standard list. Therefore, statement 2 is incorrect.
3. Since both statements are incorrect, option (D) is the answer.
