Overview: The Riverine Wonder of the Terai Arc
Flowing along the international boundary between India and Nepal in the northern sector of Bahraich district in Uttar Pradesh, Katerniaghat Wildlife Sanctuary encompasses 400.09 square kilometers of dense alluvial Sal forest, towering riverine grasses, and crystal-clear braided river channels.
Established in 1975 under the Wildlife (Protection) Act of 1972 and brought under Project Tiger coverage in 2000 as an integral constituent of the greater **Dudhwa Tiger Reserve**, Katerniaghat preserves the pristine, free-flowing channel of the **Girwa River** (which descends directly from Nepal's Karnali River system).
The sanctuary forms an indispensable biological stepping stone connecting Dudhwa National Park and Kishanpur Wildlife Sanctuary in India with Nepal's **Bardia National Park** via the trans-boundary **Khata Corridor**. The Girwa River represents one of the world's three most crucial surviving natural breeding strongholds for the critically endangered **Gharial** (Gavialis gangeticus), alongside thriving pods of **Gangetic River Dolphins** (Platanista gangetica) and hunting territories of **Royal Bengal Tigers** (Panthera tigris).
Girwa River Hydrology & Terai Ecosystems
Katerniaghat's aquatic and terrestrial ecosystems are shaped by the perennial glacial flows of the Girwa:

Faunal Diversity & Riverine Apex Predators
Katerniaghat supports an exceptional convergence of aquatic and terrestrial apex species:
Gharial
Gavialis gangeticus • Fish-eating Specialist
A flourishing breeding population of over 100 wild gharials nests along the sandbanks of the Girwa River.
Gangetic River Dolphin
Platanista gangetica • Freshwater Cetacean
Playful pods inhabit the deep river pools of the Girwa and Ghaghara, frequently surfacing with gentle exhalations.
Royal Bengal Tiger
Panthera tigris tigris • Apex Predator
Resident tigers patrol both the Sal woodlands and dense riverine reedbeds, swimming across channels to hunt prey.
Smooth-coated Otter
Lutrogale perspicillata • River Hunter
Highly social carnivores hunting fish in coordinated family packs along secluded river islands and backwaters.
Asian Elephant
Elephas maximus • Trans-Boundary Herds
Migrates across the Khata corridor between Nepal and Katerniaghat, foraging in tall elephant grass meadows.
Mugger Crocodile
Crocodylus palustris • Broad-snouted Crocodilian
Shares the river system with gharials, basking on mudflats and hunting larger terrestrial mammals at drinking points.
Avian highlights include over **300 bird species**, featuring the **Great Hornbill**, **Bengal Florican**, **Pallas's Fish Eagle**, **Lesser Adjutant Stork**, **Black-necked Stork**, and **Crested Kingfisher**.
The Khata Corridor & Indo-Nepal Conservation
Katerniaghat occupies a cornerstone position in global conservation geography. The **Khata Corridor** represents an unbroken 5-kilometer ecological bridge connecting the sanctuary's northern forests with the southern boundary of Nepal's **Bardia National Park**. Wild tigers, One-horned Rhinos, and elephant breeding herds regularly cross this international boundary without human disturbance.
The Uttar Pradesh Forest Department and WWF-India operate joint community anti-poaching squads and boat patrols equipped with solar-powered GPS trackers. The local Tharu indigenous communities actively participate in protecting river sandbars from cattle trampling during the delicate spring Gharial egg-laying season.
Eco-tourism boat safaris operated by trained local boatmen provide visitors with silent, non-motorized river journeys along the Girwa, ensuring zero acoustic disturbance to resting dolphins and nesting waterbirds.
