Agasthyamalai Biosphere Reserve at the Southern End of Western Ghats

India's Agasthyamalai Biosphere Reserve is a unique site that is located in the Western Ghats in the Southern part of India. The Biosphere Reserve has exorbitant peaks that reach up to 1,868 meters above the sea level and consists mostly of tropical forests that are home to about 2,254 species of plants (out of which 400 are endemic). The Biosphere Reserve acts as a unique genetic reservoir for cultivated plants, like- Cardamom, Jamune, Nutmeg, Pepper and Plantain. The Agasthyamalai Biosphere also holds some major wildlife sanctuaries, namely- Shendurney Wildlife Sanctuary, Peppara Wildlife Sanctuary, Neyyar Wildlife Sanctuary and Kalakkad Mundanthurai Tiger Reserve. The Biosphere reserve is also inhabited by many tribal settlements, amounting up to a total population of 3,000. These communities rely majorly on the biological resources for their survival.

Socio-economic Characteristics

Agasthyamalai Biosphere Reserve is also home to the Kani tribes from Kerala and Tamil Nadu. With over 30,000 inhabitants here, the Kani tribe is one of the oldest surviving ancient tribes in the world. It is also known as Kanikaran. This tribal settlement relies on the biological resources for their survival here. The area's indigenous tribe, Kanikaran, relies on the forests and its 14 rivers for their sustenance. They indulge in activities like fishing, agriculture and hunting. They are widely popular for their immense knowledge about medicinal plants and usually reside in huts of bamboo here. Many of these people work as guides to acquaint the visitors about the biosphere reserve. Nowadays, many programs are started to curb the exploitation of biological resources by these settlements by UNESCO.


The scientific management of Agasthyamalai Biosphere Reserve is done by the guidelines of the Indian Ministry of Environment and Forests by the coordination of a local committee and a state level Biosphere management committee. This Biosphere Reserve plays a crucial role in the diversity of our country and hence should be protected and properly managed.

In 2016, Agasthyamalai Biosphere Reserve was included in the World Network of Biosphere Reserves by UNESCO, being an ideal example of India's success in maintaining and preserving a forest biosphere. In 2001, the biological richness of the area compelled the-then Union Minister of Environment and Forest T R Balu to announce the transformation of the area in a Biosphere Reserve. The site exhibits gushing waterfalls, lush forests, a pristine stream of cleat water and tranquillity all around. Humans are allowed only in the buffer zone of the biosphere reserve. To keep the site peaceful and hassle-free, just 100 visitors a day are allowed. It is an incredibly famous tourist spot, primarily because of the two-day trek to the peak in Neyyar Sanctuary. This trek only operates in January and February, as allowed by the forest department. This biosphere reserve indeed highlights the harmonious bond between human and nature. After being listed under the UNESCO World Biosphere Reserve Network, the site has seen immense popularity among the masses.
