Site description Maenam Wildlife Sanctuary is located on the Maenam-Tendong ridge which runs north-south bisecting Sikkim longitudinally and is drained by the Tista river to the East and Rangit river in the West. The altitudinal gradient of 2,100 m - 3,300 m provides for a range of microclimates and floral diversity from subtropical forests to stabilized scree slopes. These diverse forest types in turn shelter a wide range of faunal elements. The Sanctuary has tremendous watershed value, being the only source of perennial water on this ridge. The South District headquarters, Namchi, situated 30 km due south totally depends on the water piped from the Burmelly stream originating from within the Sanctuary precincts. The adjoining town of Ravangla also depends on the Sanctuary for potable water. “Maenam-la” translates to the “Treasury of Medicines”, being a rich trove of medicinal plants. There is also a historical Buddhist monastery, the Maenam Gompa, at the top of the ridge. Interestingly, despite the disturbance from nearby urban areas, Maenam harbours a rich bird diversity (Anon. 2001). The entire stretch of forest along Temi-Tarku-Damthang-Tendong- Bhanjyang- Ravangla-Maenam and further north linking with Karjee-Labdang forests of the Khangchendzonga Biosphere Reserve is virtually contiguous, planted in a few places with the exotic Cryptomeria japonica trees. Tea plantations of the State Government occupy a part of Temi.
