Projects in the South Asia Bioregion
Restoring and reconnecting 11 protected areas at the base of the Himalayas
WWF is poised to undertake the single largest tiger, rhino, and elephant habitat conservation initiative ever in the Terai Arc.
This project will link 11 protected areas along the base of the Himalayas, from Nepal's Royal Chitwan National Park to Corbett National Park in India.The Terai Arc conservation landscape covers 30,000 square kilometers, including the Western Terai and Central Terai, which are two of the most important AREAS priorities for the Greater one-horned rhinoceros.
Extensive habitat restoration and rhino translocations will be part of this endeavor. Poaching remains a significant threat to rhinos and tigers in this region, and WWF will strengthen existing anti-poaching units.

* Elephant population data are for the most part speculative at best. Several elephant populations have likely continued to decline, making it even more likely that numbers presented here have significant margins of error.
