Camera traps outside Corbett Tiger Reserve reveal high tiger density

Vital wildlife corridor must be preserved
March 2012. A few weeks after the first eyewitness photo documentation of a wild tiger crossing the Kosi River corridor in northern India's Terai Arc Landscape, WWF-India's field team working in the area led by Meraj Anwar, Senior Project Officer, has collected camera trap photo evidence of the corridor being used by at least 13 tigers, highlighting its importance for the area's big cats.

As part of the All India Tiger Estimation, in 2010 a WWF-India study in the Ramnagar Forest Division estimated a density of 15 tigers per 100 sq. km - the highest outside a tiger reserve anywhere in India, and probably the world. Building on these findings WWF-India initiated a study using camera traps to identify tigers residing along the periphery of Corbett Tiger Reserve adjoining Kosi River.
Helping save the tigers' haven
The Terai Arc Landscape (TAL) is spread from near River Yamuna in the west to River Bhagmati in Bihar in the east stretching along India's border with Nepal. Its most important source population for wild tigers is the Corbett block, which has a density of 17.8 tigers per 100 sq. km, the highest in India. Ramnagar Forest Division's estimated density of 15 tigers per 100 sq. km. is much higher than some of India's important tiger reserves.
