Due to their restricted distribution range and dwindling population endemic and threatened species need considerable attention from ecologists. Sikkim is a part of the Eastern Himalayas Endemic Bird Area that represents high concentrations of globally threatened species. This study collected information on endemic and threatened birds of Sikkim using point count method.

A close look at the agricultural scenario in the hill state of Sikkim reveals that foodgrain production has been growing more slowly than population. The state has failed to augment agrarian reforms and public investment in agriculture has been on the decline.

Glaciologists are arguing over how a highly contentious claim about the speed at which glaciers are melting came to be included in the latest report of the Intergovernmental Panel on Climate Change.

We examined the spatial distribution pattern of reptiles in an eastern Himalayan elevation gradient. The factors governing the distribution have been assessed with emphasis on the mid-domain effect. We surveyed reptiles along the elevation gradient (300–4800 m) of the Teesta valley in Sikkim, Eastern Himalaya, India using time constrained visual encounter survey.

At a time when the impact of global warming and human activities have been recognised as threats to Northeast India, a report by the World Wide Fund for Nature (WWF) has emphasised the need for concerted action to protect the Eastern Himalayan region.

In this latest report ICIMOD has highlighted the vulnerability of the Eastern Himalayan ecosystems to climate change as a result of their ecological fragility and economic marginality.

The Eastern Himalayan region has been proposed as another National Agricultural Biodiversity Heritage Site, based on six indices. The region is the richest in species diversity among the northeastern states of India. It is the center of diversity for several widely distributed plant taxa and a crucible for speciation encompassing several primitive familities.

Out of the 353 new flora and fauna species discovered in Eastern Himalayas between 1998-2008, 19 were found in Sikkim, stated a latest WWF report.

Aspects of life history and morphometry of Günther’s oriental slender snake Trachischium guentheri (Boulenger, 1890) was studied along the Lachen and Lachung valleys of North Sikkim, Eastern Himalaya, India during 2003 – 2005. A total of 360 snakes were observed in 1026 man-hours of time constrained visual encounter surveys. Females were significantly larger (t = 3.19, df = 144, P

As many as 353 new species of flora and fauna have been discovered in the Eastern Himalayas in the past decade, of which more than 40 per cent were found in the eight states of the Northeastern region.
