The hills surrounding Kotagiri town in Nilgiri, are covered with acres of tea plantation. It becomes difficult to see a hillside like this, that breathes with species of plants and trees other than tea plantation. Most of Nilgiri has lost its indigenous tree cover of Shola forest, and has been replaced with tea plantations, plantations of eucalyptus and teak trees. The Shola trees have high ecological significance in protecting the waters of rivers by holding up of water received by precipitation, and they are home for several birds, animals and insects. A well pruned hillside is a scar and a threat to ecology.
