Nepal in Many ways
With diverse ecology Nepal is divided into three East-West ecological zones: The Northern Range – the Mountain, the Mid-Range – Hill, and the Southern Range – Terai (flat land). The geographic boundary of Nepal starts from the flat southern plains in Terai Mukhiya Patti Musharniya of Dhanusha District at 59 M to the sky-piercing peaks of the Himalayas within a breadth of 200 km in the north at 8848 m Mt. Sagarmatha. Sagarmatha is the highest point on Earth.
From Tarai (59M to 305M) Further north, the Siwalik zone (700 – 1,500 M ) and the Mahabharat range (1,500 M - 2,700 M) give way to the Duns (valleys) known as Inner Terai, such as Trijuga, Sindhuli, Chitwan, Dang, and Surkhet. The Midlands (600 – 3,500 m), north of the Mahabharat range are beautiful valleys of Kathmandu and Pokhara. The mountainous region starts at 3000 M leading up to the alpine pastures and temperate forests limited by the tree line at 4,000 M and the snow line beginning at 5000 M. The inner Himalayan valley (above 3,600 M) such as Mustang and Dolpo are cold deserts sharing topographical characteristics with the Tibetan plateau.
