Notes: India’s largest open-air fernery has been inaugurated in Uttarakhand’s Ranikhet.

This center has been developed for conservation of fern species and also to create awareness about their ecological role and promote further research. The newly inaugurated fernery is one of the biggest ferneries in India. The fernery has the largest collection of fern species, second to only Jawaharlal Nehru Tropical Botanical Garden and Research Institute (TBGRI), Thiruvananthapuram. However, it is the country’s first open-air fernery in natural surroundings which is not under any poly-house/ shade house.
