Endemism- Species confined to a region and not found elsewhere
Hot spots- Western Ghats
Sacred Groves- Jaintia hills of Rajasthan
Ex situ conservation- Zoological parks
Sacred groves of India are fragments of forests which are of varying sizes, are communally protected, and generally, have a significant religious connotation for the protecting community. In these areas hunting and logging are usually strictly prohibited. Thus, rare endangered and endemic taxa can be found intact and flourishing in these places. Examples include Khasi and Jaintia Hills in Assam and Meghalaya.
So, the correct answer is 'Sacred Groves- Jaintia hills of Rajasthan'.
