Don&rsquot let its size fool you. Longwood Shola, the little forest located in the Kotagiri taluk of Tamil Nadu&rsquos Nilgiris district, is a very big deal. For one, it is an unexpected gem &mdash a sparkling island of a forest in a sea of villages, tea estates and plantations of exotic trees. Longwood is also one of the last remnants of the primeval forests that once clothed the Nilgiris. It has taken zealous guarding and action by conservationists and locals to keep even these 100-odd hectares safe.
