In Sikkim at least 17 large hydropower projects on the Teesta River and its tributaries have their environmental clearances in place, despite warnings, improper assessments and negotiated conditions. At a point of time when a natural seismic occurrence has shaken the stability of an already unpredictable Himalayan ecosystem, it is important to revisit the concept of hydropower projects as a green, clean and safe option.

Sikkim is a small, mountainous, Indian state (7,096 km2) located in the eastern Himalayan region. Though a global biodiversity hotspot, it has been relatively less studied. A detailed forest type, density and change dynamics study was undertaken, using SATELLITE remote sensing data and intensive field verification.

Understanding diversity patterns and the mechanisms underlying those patterns along elevational gradients is critically important for conservation efforts in montane ecosystems, especially those that are biodiversity hotspots. Despite recent advances, consensus on the underlying causes, or even the relative influence of a suite of factors on elevational diversity patterns has remained elusive.

Sikkim is a small, mountainous, Indian state (7,096 km2) located in the eastern Himalayan region. Though a global biodiversity hotspot, it has been relatively less studied. A detailed forest type, density and change dynamics study was undertaken, using satellite remote sensing data and intensive field verification. The landscape was found to be dominated by alpine and nival ecosystems, with a large portion above the tree line, considerable snow cover, and a sizeable area under forest cover (72%,
5,094 km2).
