Assam CM highlights ‘big comeback’ of ‘small hog’
2-minute summary
The Pygmy Hog (Porcula salvania), the world's smallest and rarest wild pig, has staged a remarkable recovery in Assam. From a critical low of just six individuals captured for captive breeding in 1996, the population has grown to 194 in 2026. This success is driven by the Pygmy Hog Conservation Programme (PHCP)—a collaborative initiative involving the Durrell Wildlife Conservation Trust, the Assam Forest Department, the IUCN Wild Pig Specialist Group, the Union Ministry of Environment, Forest and Climate Change (MoEFCC), and local NGOs Aaranyak and Ecosystems India. As a key indicator species for grassland health, the pygmy hog's recovery is vital for the region's alluvial grassland ecosystems. Reintroduction efforts since 2008 have successfully established wild populations in Manas National Park, Orang National Park, Bornadi Wildlife Sanctuary, and Sonai-Rupai Wildlife Sanctuary, with a long-term target of reaching 300 self-sustaining wild individuals by 2040.
Why it's in the news
Assam Chief Minister Himanta Biswa Sarma highlighted the successful recovery of the endangered pygmy hog, noting that its population has increased from six in 1996 to 194 today through a dedicated captive breeding and reintroduction programme.
Background and context
The pygmy hog was once widespread across the narrow strip of tall, wet grasslands along the southern foothills of the Himalayas in India, Nepal, and Bhutan. By the mid-20th century, habitat loss, degradation, agricultural encroachment, and uncontrolled dry-season burning of grasslands pushed the species to near extinction, leading many to believe it was extinct. It was rediscovered in 1971 in Assam's Manas National Park. To prevent its extinction, the Pygmy Hog Conservation Programme (PHCP) was initiated. In 1996, six wild hogs were captured from the Bansbari range of Manas National Park to start a captive breeding facility in Guwahati. Following systematic breeding, the first batch of captive-bred hogs was reintroduced into the wild in 2008, marking a milestone in Indian wildlife conservation.
Constitutional provisions
- Article 48A — Directs the State to endeavor to protect and improve the environment and to safeguard the forests and wildlife of the country.
- Article 51A(g) — Imposes a fundamental duty on every citizen of India to protect and improve the natural environment including forests, lakes, rivers, and wildlife.
Government schemes
- Integrated Development of Wildlife Habitats (IDWH) — A centrally sponsored scheme that provides financial and technical assistance to state governments for wildlife conservation, including recovery programmes for critically endangered/endangered species.
International organisations
- IUCN (International Union for Conservation of Nature) — Its Wild Pig Specialist Group is a key collaborator in the Pygmy Hog Conservation Programme. The IUCN Red List tracks the species' conservation status (currently listed as Endangered).
- Durrell Wildlife Conservation Trust — A UK-based international charity founded by naturalist Gerald Durrell that initiated the pygmy hog conservation effort in 1971 and remains a primary collaborator.

Mains practice: The success of the Pygmy Hog Conservation Programme (PHCP) highlights the efficacy of ex-situ conservation transitioning into in-situ recovery. Analyze the challenges and opportunities of captive breeding programs in restoring endangered species in India.
The Pygmy Hog (Porcula salvania), the world's smallest and rarest wild pig, has seen its population rise from 6 in 1996 to 194 in 2026 through the Pygmy Hog Conservation Programme (PHCP). This success showcases how structured ex-situ captive breeding can feed into in-situ wild reintroduction to save species from the brink of extinction.
• **Opportunities of Captive Breeding Programs**:
- **Preventing Immediate Extinction**: It provides a safe, controlled environment for species with critically low wild populations, shielding them from immediate threats like poaching or habitat loss.
- **Scientific Research and Monitoring**: Captivity allows conservationists to study reproductive biology, health, and behavioral traits that are difficult to observe in the wild.
- **Controlled Reintroduction**: It enables the gradual acclimatization and soft-release of species into restored habitats, as seen in the successful reintroduction of pygmy hogs in Manas, Orang, and Bornadi.
- **Global and Local Collaboration**: It fosters partnerships between international bodies (e.g., Durrell Trust), government agencies (MoEFCC, State Forest Departments), and local NGOs (e.g., Aaranyak), pooling resources and expertise.
• **Key Challenges**:
- **Genetic Bottleneck**: Breeding from a very small founder population (e.g., only six individuals in 1996) risks inbreeding depression and reduced genetic diversity, making the species vulnerable to diseases.
- **Habitat Restoration Gaps**: Reintroduction cannot succeed unless the original threats in the wild—such as grassland burning, invasive weeds, and encroachment—are actively managed.
- **Risk of Disease Transmission**: Captive populations are highly vulnerable to infectious outbreaks (e.g., African Swine Fever) which could wipe out the entire gene pool.
- **High Resource Demands**: These programs require long-term financial commitment, specialized veterinary care, and sustained inter-agency coordination over decades.
In conclusion, the recovery of the Pygmy Hog demonstrates that captive breeding is not an end in itself, but a vital bridge to ecological restoration. For long-term viability, India must pair such species recovery programs with robust, community-led habitat protection policies.
Prelims practice questions
Q1. With reference to the Pygmy Hog (Porcula salvania), consider the following statements: 1. It is the world's smallest and rarest wild pig. 2. It is endemic to the tall, wet grasslands of the southern Himalayan foothills. 3. It is currently classified as 'Critically Endangered' on the IUCN Red List. Which of the statements given above are correct?
- 1 and 2 only
- 2 and 3 only
- 1 and 3 only
- 1, 2 and 3
Answer: A. Statements 1 and 2 are correct. The Pygmy Hog is the world's smallest wild pig and is endemic to the tall, wet alluvial grasslands of the Himalayan foothills (primarily found in Assam). Statement 3 is incorrect because the Pygmy Hog was downlisted from 'Critically Endangered' to 'Endangered' by the IUCN in 2019 due to successful conservation and reintroduction efforts.
Q2. In which of the following protected areas of Assam can reintroduced populations of the Pygmy Hog be found? 1. Manas National Park 2. Orang National Park 3. Bornadi Wildlife Sanctuary 4. Sonai-Rupai Wildlife Sanctuary Select the correct answer using the code given below:
- 1 and 2 only
- 1, 2 and 3 only
- 3 and 4 only
- 1, 2, 3 and 4
Answer: D. All four protected areas are correct. Under the Pygmy Hog Conservation Programme (PHCP), captive-bred pygmy hogs have been reintroduced and established in Sonai-Rupai Wildlife Sanctuary, Bornadi Wildlife Sanctuary, Orang National Park, and Manas National Park.
Q3. The Pygmy Hog is considered an important 'indicator species' for which of the following ecosystems?
- Alluvial grasslands
- Alpine meadows
- Tropical evergreen forests
- Mangrove swamps
Answer: A. The pygmy hog is a sensitive indicator species for the health of tall, wet alluvial grasslands. Its presence indicates a well-managed, healthy grassland ecosystem, which is also critical for other threatened species like the one-horned rhinoceros and swamp deer.
