Wild Boar Terai Nepal: The Powerful Pig of the Forest Floor
Wild boar are abundant throughout Nepal's Terai and are a key prey species for tigers. Their night-time foraging raids on crops make them both wildlife attraction and agricultural challenge.
Overview
The wild boar (Sus scrofa) is one of the most widespread and adaptable large mammals in Nepal, found from the Terai lowlands up to mid-hill forests at 1,800 m altitude. In the Terai, they are an important prey species for tigers and leopards, and their rooting behaviour turns over soil in ways that benefit grassland ecosystems. Adult males (boars) carry impressive tusks -- the lower canines protrude upward from the jaw and can reach 12 cm -- and weigh up to 150 kg.
Viewing in Chitwan and Bardia
Wild boar are seen on virtually every Chitwan jeep safari, particularly in the grassland sections where they root for tubers and grasses. Family groups of six to twenty animals, typically one dominant male, several females, and striped piglets, are common sights near water sources. The striped pattern of piglets fades as they mature into the uniformly dark grey-brown of adults.
They are most active at dawn and dusk and can often be heard before being seen -- their rooting creates loud snuffling sounds in dry leaf litter. After dark, boar frequently leave the park to raid crops in buffer zone villages, creating conflict with farming communities.
Behaviour Around Humans
Wild boar are generally non-aggressive toward humans unless cornered, injured, or -- in the case of females -- protecting piglets. Males can be dangerous if they feel threatened. On walking safaris, guides keep groups away from boar resting areas in thick cover.

FAQ
Are wild boar important for tiger conservation?
Yes. Wild boar are a primary prey species for Bengal tigers, second only to spotted deer in biomass consumed. Protecting boar populations directly benefits tiger recovery.
Can wild boar climb trees?
No, but they are strong swimmers and readily cross rivers. They can run at up to 45 km/h over short distances.
Do wild boar carry diseases transmissible to humans?
They can carry trichinella and leptospira bacteria. No handling or approach without a guide is advised, and any meat from wild animals should never be consumed.
