After the independence the population of tiger in India suffered a heavy decline due to many reasons. The primary reason was noticed as deforestation activity done by local people to earn their livelihood. Diversion of land was started just to accelerate the development activities like irrigation, hydro-electric projects, road/rail construction. The early king's hobbies were sport hunting and poaching of tigers for trophies. These activities led the sudden decrease of tiger population in Corbett. Visitors staying at Dhikala forest lodge and if they move towards the Kanha ridge can enjoy the spectacular natural beauty of Patli Dun Valley. The elongated valley between the Himalayas and Shiwalik mountain ranges is called Duns. It is formed by the Ramganga River. The valley is covered with gravel and boulders formed by the erosion of Himalayas and Shiwalik uplands. Northern half of the Corbett is covered by one such Dun called Patli Dun which is best visible from the Dhikala zone and Kanda being situated at the high altitude of the park which reflects a splendid view of the valley.
