The Nilgiri Biosphere Reserve is an International Biosphere Reserve in the Western Ghats and Nilgiri Hills ranges of South India. The Nilgiri Sub-Cluster is a part of the Western Ghats, which was declared a World Heritage Site by UNESCO in 2012.[1] It is the largest protected forest area in India, spreading across Tamil Nadu, Karnataka and Kerala.[2] It includes the Aralam, Mudumalai, Mukurthi, Nagarhole, Bandipur and Silent Valley national parks, as well as the Wayanad, Karimpuzha, and Sathyamangalam wildlife sanctuaries.

A fascinating ecosystem of the hill ranges of Nilgiris and its surrounding environments covering a tract of over 5000 square kilometers was constituted as Nilgiris Biosphere Reserve by UNESCO in September 1986 under Man and Biosphere Programme. Nilgiris Biosphere Reserve is India's first and foremost biosphere reserves with a heritage, rich in flora and fauna. Tribal groups like the Badagas, Todas, Kotas, Irullas, Kurumbas, Paniyas, Adiyans, Edanadan Chettis, Allar, Malayan, etc., are native to the reserve.[3]

The reserve extends from the tropical and subtropical moist broadleaf forests, tropical moist forests of the western slopes of the Ghats to the tropical and subtropical dry broadleaf forests tropical dry forests on the east slopes. Rainfall ranges from 500mm to 7000mm per year. The reserve encompasses three ecoregions, the South Western Ghats moist deciduous forests, South Western Ghats montane rain forests, and South Deccan Plateau dry deciduous forests.

Flora

Main article: List of endemic plants in the Nilgiri Biosphere Reserve

The Nilgiri Biosphere Reserve is very rich in plant diversity. Tropical rainforest habitat is dominant but Montane forest and Tropical moist forest habitats are also found. About 3,300 species of flowering plants can be seen here. Of the 3,300 species, 133 are endemic to the reserve. The genus Poeciloneuron is exclusively endemic to the Nilgiris. Some of the plants entirely restricted to the Nilgiri Biosphere Reserve include species of Adenoon, Calycanthus, Baeolepis, Frerea, Jarodina, Wagatea, Poeciloneuron, etc.

Of the 175 species of orchids found in the Nilgiri Biosphere Reserve, eight are endemic. These include endemic and endangered species of Vanda, Liparis, Bulbophyllum and Thrixspermum. The Shola montane temperate grasslands of the reserve are a treasure house of rare plant species.

About 80% of flowering plants reported from Western Ghats occur in Nilgiri Biosphere Reserve.[5]
