The hispid hare: the wild rabbit hiding in India's Terai grasslands

The animal that shares the most biological ground with your pet rabbit is not the European wild rabbit most people picture. It is a short-eared, bristle-coated creature that lives in a narrow strip of tall grassland along the southern edge of the Himalayas, and most wildlife biologists consider it among the most endangered small mammals in Asia.

The hispid hare, known to science as Caprolagus hispidus, belongs to the order Lagomorpha, the same group that includes domestic rabbits and hares. It is the only member of its genus, which puts it in a category of biological uniqueness that very few animals occupy. The name comes from the Latin hispidus, meaning bristly or rough, and the coat earns it: coarse, dark brown fur on the back, paler underneath, with none of the softness that makes pet rabbits appealing to touch. The ears are short and rounded for a lagomorph, the legs are stocky, and the animal moves through grass rather than running across open ground.

The hispid hare is found only in the Terai, the flat, seasonally flooded belt of tall-grass habitat that runs through parts of Uttar Pradesh, Bihar, West Bengal, and into Nepal and Bhutan. It depends almost entirely on tall grassland dominated by species such as Saccharum spontaneum and Imperata cylindrica. These grasses, which can grow to three or four metres, are the animal's cover, its food source during the dry season when it strips the base of young shoots, and the structure it uses to hide from predators.

That habitat has contracted sharply. Conversion to agriculture, controlled burning at the wrong time of year, and the spread of invasive plant species have reduced the tall grassland patches that remain to fragments. The hispid hare is listed as Endangered on the IUCN Red List. Viable populations are believed to survive in Dudhwa National Park in Uttar Pradesh, Chitwan and Bardia in Nepal, and a handful of other protected areas. Outside protected land, confirmed sightings are rare enough that each one is documented.

Pet rabbits descend from the European wild rabbit, Oryctolagus cuniculus, a species domesticated over centuries to tolerate handling, live in social groups, and thrive in a wide range of environments. The hispid hare is not domesticated, has never been domesticated, and is not a candidate for it. It is solitary and territorial, active at dawn and dusk, and highly sensitive to disturbance. Attempts to keep captured individuals in captivity have not succeeded in establishing a breeding population, and the animal is fully protected under Schedule I of the Wildlife Protection Act, 1972, the same schedule that covers tigers and elephants. Keeping one is not a grey area; it is a serious wildlife offence.

The biological connection to pet rabbits is real but distant. Both are lagomorphs, both have the same digestive system design, hindgut fermenters that pass food twice to extract maximum nutrition, and both share the characteristic lagomorph skull structure. That is roughly where the similarity useful to a rabbit owner ends. The hispid hare's behaviour, social structure, and habitat requirements are entirely its own.

Conservation work for the hispid hare centres on grassland management: ensuring that tall grass is allowed to regenerate after seasonal burning, that buffer zones around protected areas retain enough unbroken habitat to support small populations, and that the species is monitored consistently enough to detect further decline. Camera trap surveys and local ranger networks have improved the picture of where populations persist, but the animal's secretive habits and low density make population estimates difficult.

The broader Terai ecosystem that the hispid hare depends on is also home to the greater one-horned rhinoceros, the Bengal florican, and several other species that need the same tall grassland. Conservation efforts that protect the grassland protect all of them together, which is one reason the hispid hare sometimes appears in arguments for grassland preservation even when the flagship species in a given park is something larger.

For a rabbit owner, the hispid hare is not a story about a pet or a potential pet. It is a reminder that the domesticated animal on a living-room floor is one point in a much longer lineage, and that the wild end of that lineage is quietly running out of room.
