The Sukla Phanta Wildlife Reserve is a protected area in the Terai of the Far-Western Region, Nepal, covering 305 km (118 sq mi) of open grassland, forests, riverbeds and tropical wetlands at an altitude of 174 to 1,386 metres (571 to 4,547 ft).[1] It was gazetted in 1973 as Royal Sukla Phanta Wildlife Reserve. A small part of the reserve extends north of the East-West Highway to create a corridor for seasonal migration of wildlife into the Sivalik Hills. The Syali River forms the eastern boundary southward to the international border with India, which demarcates the reserve’s southern and western boundary.[2]
