Pygmy hog (Porcula salvania) is an endangered species of small wild pig, previously spread across the terai in India, Nepal, and Bhutan but now only found in Assam. The current world population is about 150 individuals or fewer. Recent conservation measures have increased the prospect of survival in the wild of this critically endangered species
They are about 55 to 71 cm long and stand at 20-30 cm with a tail of 2.5 cm. They weigh 6.6 to 11.8 kilograms. Their skin is dark brownish black and the fur is dark. Piglets are born brown with very faint yellowish stripes along the body length. The head is sharply tapered and they have a slight crest of hair on the forehead and on the back of the neck. Adult males have the upper canines visible on the sides of the mouth. They live for about 8 years, becoming sexually mature at 1-2 years. They breed seasonally before the monsoons giving birth to a litter of 3-6 after a gestation of about 115 days. In the wild they make small nests by digging a small trench and lining it with vegetation. During the heat of the day they stay within these nests. They feed on roots, tubers, insects, rodents, and small reptiles.
The pygmy hog is the sole representative of Porcula, making the conservation of this critically endangered species even more important as its extinction would result in the loss of a unique evolutionary branch of pigs. They used to be widespread in the tall, wet grasslands in the southern Himalayan foothills from Uttar Pradesh to Assam, through Nepal and north Bengal. However, human encroachment has largely destroyed the natural habitat of the pygmy hog by development, agriculture, domestic grazing and deliberate fires. Only one viable population remains in the Manas Tiger Reserve, but even there threats due to livestock grazing, poaching and fire persist. The total wild population has been estimated as less than 500 animals and the species is listed as "critically endangered" (Oliver, 1980; Oliver & Deb Roy, 1993; Pigs, Peccaries and Hippos Status Survey and Action Plan, 1993; Narayan, 2006). Their rarity contrasts greatly with the massive population of wild boars (Sus scrofa) in India.
Conservation of the species has been hampered due to the lack of public support, unlike that for charismatic South Asian mammals like the Bengal Tiger or Indian Rhino. Local political unrest in the area has also severely hampered effective conservation efforts, but these conflicts have now ceased.Pygmy hogs were exhibited in the zoos of London in the 19th century. Neither was captivity aimed at conservation nor did these captive populations survive. Zürich Zoo exhibited pygmy hogs from 1976 to 1978, but all females died. The success of captive breeding dramatically increased after the Pygmy Hog Conservation Programme, PHCP, was established in 1995. The PHCP was established under the umbrella of a formal 'International Conservation Management and Research Agreement' by the Durrell Wildlife Conservation Trust, the IUCN's Pigs, Peccaries and Hippo Specialist Group, the Forest Department, Government of Assam, and the Ministry of Environment and Forests, Government of India. Durrell Wildlife Conservation Trust has launched a comprehensive conservation strategy including field status surveys of pygmy hogs and their habitats, behavioural studies, personnel training, local community awareness and assistance programmes and the establishment of a highly successful captive breeding program at the Pygmy Hog Research and Breeding Centre in Assam. Active habitat management has been established and a reintroduction programme has now been launched (Narayan, 2006).
The Success Story
Dr Goutam Narayan of Durrell Wildlife and EcoSystems-India said,"By 1964, the pygmy hog was thought to be extinct with no sightings reported for several years. Then in 1971, four pygmy hogs were recovered from a market in Paneri in north Assam and that gave everyone cause for hope."
After 12 years of patient conservation effort, which began with six wild pygmy hogs, Assam Forest officials and experts from the Pygmy Hog Conservation Programme (PHCP) have now released 16 hogs into the Sonai Rupai wildlife sanctuary, about 175km (110 miles) north of the state capital, Guwahati.

Dr Narayan is the man who deserve the credit for the success of the programme.
Assam's chief wildlife warden MC Malakar said,"This is a great day in the history of animal conservation throughout the world and we are proud of the achievement."
This is just the beginning of a new hope to see the pygmy hogs in the wild. But it is only possible with support from each one of us, who has a moral resposibility towards our environment. What we can do is to get more information and inform the ignorant to prevent further damage to the habit of these animals.
Let us Save the Planet which is in CRISIS!
