Threats to the ecology: Western ghats is one of the most important teritory for biodiversity in India and many fishes of the aquarium hobby comme from the western Ghats.
In August 2011, the Western Ghats Ecology Expert Panel designated the entire Western Ghats as an Ecologically Sensitive Area and assigned three levels of Ecological Sensitivity to its different regions. The panel, headed by ecologist Madhav Gadgil, was appointed by the Union Ministry of Environment and Forests to assess the biodiversity and environmental issues of the Western Ghats.The Gadgil Committee and its successor, the Kasturirangan Committee, recommended suggestions to protect the Western Ghats. The Gadgil report was criticised as being too environment-friendly and the Kasturirangan report was labelled as being anti-environmental.

In 2006, India applied to the UNESCO Man and the Biosphere Programme for the Western Ghats to be listed as a protected World Heritage Site
