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.
