Swamp Deer (Barasingha) in Nepal
An endangered grassland deer of the western Terai, famed for its many-tined antlers and large herds.
The swamp deer, known across the subcontinent as the barasingha (Rucervus duvaucelii), is an endangered grassland deer that survives in Nepal only in the western Terai, where it gathers in some of the largest herds of its kind on Earth. Famed for the many-tined antlers of its stags, it is a flagship for the country's increasingly rare lowland grasslands.
Description
The swamp deer is a large, handsome deer with a coarse, yellowish-brown coat that turns richer in the cool season. Mature stags carry the magnificent branching antlers that earn the name barasingha, literally "twelve-tined," often with well over a dozen points. As the name suggests, it favours wet grasslands and marshy ground, and its splayed hooves help it move across soft, flooded terrain. Highly social, it lives in herds that can number into the hundreds in the best habitat.
Where to see it in Nepal
The stronghold is Shuklaphanta National Park in the far-western Terai, whose vast open grasslands, or phantas, support one of the world's largest swamp deer populations and where herds of many hundreds can sometimes be seen grazing in the open. Smaller numbers live in Bardia National Park along the Karnali floodplain. Early-morning jeep drives across the grasslands give the best chance of large herds.

Conservation status
The swamp deer is listed as Vulnerable globally and is strictly protected in Nepal, where it clings on in just a handful of western grassland reserves. Its decline is driven above all by the loss and conversion of grasslands to farmland and settlement, along with overgrazing by livestock, drainage of wetlands and, historically, hunting. Because it is so tied to a single, shrinking habitat type, protecting and managing the Terai grasslands, including controlled grass-cutting and burning, is central to its survival.
Best parks and season
Aim for Shuklaphanta for the spectacle of large herds, with Bardia a good add-on for a wider safari. The dry season from October to April is ideal, when cool, clear weather and cut or burned grass open up the phantas and make grazing herds easy to spot. The hot, flooded monsoon months are best avoided. As with all Terai wildlife, early morning and late afternoon are the prime viewing windows.
Behaviour and ecology
The swamp deer is a grazer of wet grasslands, feeding on grasses and aquatic plants and rarely straying far from water. Its herds provide vital prey for the Bengal tiger, making it a key part of the western Terai food web, and it shares the grasslands and floodplains with the greater one-horned rhino and with other grassland deer and antelope such as the spotted deer and blackbuck. During the rut, stags bellow and clash antlers to win mates, and the booming calls carrying across the open phantas are one of the great sounds of the Nepali grasslands.
Safari and conservation notes
Keep a respectful distance, follow your guide and avoid disturbing grazing herds, especially during the rut and calving. The future of the barasingha is tied to the future of the Terai grasslands, so supporting ethical operators and well-managed protected areas matters.

Frequently asked questions
Where can you see swamp deer in Nepal?+
The largest herds live in Shuklaphanta National Park in the far-western Terai, which holds one of the biggest swamp deer populations in the world. Smaller numbers occur in Bardia National Park along the Karnali floodplain.
What is the conservation status of the swamp deer?+
The swamp deer, or barasingha, is listed as Vulnerable globally and is strictly protected in Nepal, where it survives only in a few western Terai grasslands. Habitat loss and conversion of grasslands are its main threats.
Why is it called barasingha?+
The Hindi-Nepali name barasingha means twelve-tined, referring to the many-branched antlers of mature stags, which can carry well over a dozen points. It is one of the most striking sets of antlers of any Asian deer.
When is the best time to see swamp deer?+
The dry season from October to April is best, when cool weather and cut grasslands improve visibility. Early morning drives across Shuklaphanta's open phantas, or grasslands, offer the chance to see large grazing herds.
