The Terai Arc Landscape (TAL) is composed of 14 Indian and Nepalese trans-border protected ecosystems of the Terai (Sanskrit for "lowlands") and nearby foothills of the Himalayas. [1] [2] and encompassing 14 protected areas of Nepal and India. The area spans approximately 12.3 million acres (5 million hectares) and includes Nepal's Bagmati River to the east and India's Yamuna River to the west. [1] The TAL is home to many endangered mammals including the Bengal tiger (of which it has one of the world's highest densities), [1] [2] the Indian rhinoceros, the gaur, the wild Asian elephant, the hispid hare, the sloth bear, the South Asian river dolphin and the chital, as well as over 500 species of birds, many endangered. Examples of birds are the endangered Bengal florican, the sarus crane, and the black stork. [3]
The rivers and wetlands of the TAL are rich and diverse ecosystems with many endemic species that support, besides birds and mammals, a wide range of fish, amphibians, and fresh water crustaceans. [3] However, the area faces many challenges to the wildlife. [4] Of the 14 protected areas within the TAL, none is large enough, by itself, to sustain a population of tigers over time. If the protected areas were to be linked by wildlife corridors, individual tigers would be able to move from area to area, furthering its ability to survive long-term. [1] TAL is densely populated and its welfare is of critical importance to its human and animal life. [5] Its approximately three million people are among the world's poorest (50% live below the poverty live) and generally subsist on the land. [1] As of the beginning of 2013, the Indian government will give a donation to farmers who grow flowers in the Terai. [6]
The following are protected areas within the boundaries of the TAL: [1]
Bardiya National Park is a protected area in Nepal that was established in 1988 as Royal Bardia National Park. Covering an area of 968 km2 (374 sq mi) it is the largest and most undisturbed national park in Nepal's Terai, adjoining the eastern bank of the Karnali River and bisected by the Babai River in the Bardiya District. Its northern limits are demarcated by the crest of the Siwalik Hills. The Nepalgunj-Surkhet highway partly forms the southern boundary, but seriously disrupts the protected area. Natural boundaries for human settlements are formed in the west by the Geruwa, a branch of the Karnali River, and in the southeast by the Babai River. [7]
Together with the neighboring Banke National Park, the coherent protected area of 1,437 km2 (555 sq mi) represents the Tiger Conservation Unit (TCU) Bardia-Banke that extends over 2,231 km2 (861 sq mi) of alluvial grasslands and subtropical moist deciduous forests. [8] [9]Banke National Park is located in the Lumbini Province and was established in 2010 as Nepal’s tenth national park after its recognition as a "Gift to the Earth". [10] The protected area covers an area of 550 km2 (210 sq mi) with most parts falling in the Sivalik Hills. The park is surrounded by a buffer zone of 344 km2 (133 sq mi) in the districts of Banke, Salyan and Dang Deukhuri Districts. [11]
Together with the neighbouring Bardia National Park, the coherent protected area of 1,518 km2 (586 sq mi) represents the Tiger Conservation Unit (TCU) Bardia-Banke. [12]Parsa National Park is a national park in the Terai of south-central Nepal covering an area of 627.39 km2 (242.24 sq mi) in the Parsa, Makwanpur and Bara Districts and ranging in elevation from 435 to 950 m (1,427 to 3,117 ft) in the Sivalik Hills. It was established as a wildlife reserve in 1984 and received national park status in 2017. It is surrounded by a buffer zone since 2005 with an area of 285.3 km2 (110.2 sq mi). [14] In 2015, the protected area was further extended by 49 sq mi (128 km2). [15]
To the north of Parsa National Park, the East Rapti River and Sivalik Hills form a natural boundary to human settlements. To the east, the boundary extends up to the Hetauda–Birgunj highway; to the south, a forest road demarcates the park's boundary. To the west is Chitwan National Park, which is situated just north of Valmiki National Park, a tiger reserve in India. Thus, this transnational protected area of 2,075 km2 (801 sq mi) represents the Tiger Conservation Unit (TCU) Chitwan–Parsa–Valmiki, which covers a total of 3,549 km2 (1,370 sq mi) in the Terai–Duar savanna and grasslands. [16]
Before being converted to a protected area, the region was a private game reserve and hunting park for both the British and Nepalese elite. [14] [17]Pilibhit Tiger Reserve (pronounced [piːliːbʱiːt̪ˈtaɪɡərɪˈzɜːvː] ), is among the narrowest yet most canopy-rich tiger reserves, spread across a horseshoe-shaped landscape. [20] The reserve is known to have an estimated tiger density of 10.8 per 100 km2 area. [a] The reserve covers a total area of 730.24 km2, of which 97.6% (712.88 km2) lies in Pilibhit district and 2.4% (17.36 km2) in Shahjahanpur district, both located in the Rohilkhand region of Uttar Pradesh. [21] [22] Approximately 21% of Pilibhit district's total geographical area comes under reserve's limits, thereby positioning it in the category of Uttar Pradesh's most forest-rich districts. It consists of the Himalayan lowlands terrain along the Indo–Nepal border in the upper northern plains. The habitat is distinguished by tall grasslands, sal forests, and the swamp ecosystem, which is maintained through regular flooding events originating from nearby rivers, riverlets and lakes during the rainy seasons. The Sharda sagar dam elongating up to a length of 22 km (14 mi) is on the edge of the reserve. [23]
The core area of the reserve contains 35 species of mammals, [24] 556 avians species, [25] [26] 79 species of fishes, [27] as well as several species of reptiles and amphibians, [28] including herbivorous, carnivorous, and omnivorous fauna. In 2020, the tiger reserve was awarded the inaugural TX2 global award in recognition of its achievement in multiplying the number of tiger within the stipulated time frame. [29] As per an internal survey conducted by the authorities in 2022, the reserve has more than 99,882 animals of 22 species of different class. [30] The reserve's officials confirmed in August 2025 that the core area hosts more than 79 adult tigers. [b] [31] [32]Kishanpur Wildlife Sanctuary is a wildlife sanctuary in Uttar Pradesh, India. It covers an area of 227 km2 (88 sq mi) and was founded in 1972.
It is part of Dudhwa Tiger Reserve.{{cite web}}: CS1 maint: archived copy as title (link)
