I have visited the Peak wilderness, Horton Plains alias Maha Eliya and Knuckles range many a time. Horton Plains or Maha Eliya is now being a National Park, much attention is paid to protect it. But the other areas are open for anyone who want to enter is open for threat. Knuckles and Peak Wilderness areas have more diversity in Fauna as well as flora, and has to be protected at any cost.
My opinion is that these areas must be named as World Heritage Sites and may be special laws and methods of protection must be adopted. Especially in Knuckles Range, there are many remote villages that special attention must be put.
