Consider the following facts:

1. No human habitation is permitted inside biosphere reserves.
2. The Indian government has designated 18 sites as biosphere reserves.
3. The Thar Desert, situated in Rajasthan, has been selected by the Indian government as a potential biosphere reserve.

Which of the above given facts are true?

Biosphere reserves are another category of protected areas. Under this, a large area is declared as a biosphere reserve where wildlife is protected, but local communities are allowed to continue to live and pursue traditional activities within the reserve. The Indian government has established 18 biosphere reserves of India, (categories roughly corresponding to IUCN category V protected areas), which protect larger areas of natural habitat (than a National Park or Animal Sanctuary), and often include one or more National Parks and preserves, along buffer zones that are open to some economic uses.
