I want to know the answer to the following question:
What plays a vital role in harbouring floral and faunal species?
All the background I'm provided with is that "The forests play a vital role in harbouring more than 45,000 floral and 81,000 faunal species of which 5150 floral and 1837 faunal species are endemic.". Is that enough to answer the question?
Answer: yes
