Pygmy Hog: Key Facts

  • Scientific name: Porcula salvinia — the world's smallest wild suid and the only surviving species of the genus Porcula.
  • Endemic to the Indian subcontinent; closely associated with tall, wet alluvial grasslands of the Himalayan foothills.
  • Historical distribution: Uttar Pradesh to Assam, including Nepal's Terai and Bengal's Duars.
  • Feared extinct after decades without records; rediscovered in 1971 in Assam. Surviving wild populations now mainly restricted to Assam, especially the Manas landscape.

Physical and Biological Features

  • Smallest member of the pig family (Suidae): extremely small body, ears and tail; short medial false hooves; streamlined body; absence of facial warts.
  • Habitat: Undisturbed tall grasslands of riverine ecosystems (dense grasses, herbs, shrubs, young trees). Habitat is highly vulnerable to agricultural expansion and human settlement.
  • Acts as an indicator species of healthy tall grassland ecosystems.
  • Diet: Omnivorous — roots, tubers, shoots, worms, invertebrates, occasionally small vertebrates and eggs of ground-nesting birds.
  • Social organisation: Adult males solitary; females and juveniles in family groups of 4–6; sexes associate mainly during breeding season.
  • Reproduction: Highly seasonal; births peak in late April–May with monsoon onset; litter size 2–6 piglets (usually 3–4); both sexes build nests year-round.

Conservation Status

  • IUCN Red List: Endangered
  • CITES: Appendix I
  • Wildlife (Protection) Act, 1972: Schedule I

Conservation Efforts

  • Pygmy Hog Conservation Programme (PHCP) initiated in 1995, with major captive breeding from 1996.
  • Focus: captive breeding, disease prevention and reintroduction into the wild.

Significance

  • Conserving pygmy hog habitat (tall grasslands) supports other threatened species: Bengal florican, hispid hare, hog deer, greater one-horned rhinoceros — making it an umbrella/indicator species for grassland conservation.
  • Highlights the broader issue of grassland ecosystem neglect in Indian conservation policy, which traditionally focuses on forests.
