NUMALIGARH: With a view to providing a proper home to butterflies in the unique Butterfly Valley in Golaghat district, especially the endangered varieties, the North East Institute of Science and Technology is trying to locate and nurture plants there on which they breed.

The valley is situated inside the Numaligarh Refinery township, spread over an area of 30 acres amidst a backdrop of verdant green and surrounded by hillocks. It is adjacent to the misty Deopahar hills and the Kaliani river, and is not far away from the world-famous Kaziranga National Park either.
