Pangolins in Sri Lanka: Indian Pangolin Conservation on an Island

Sri Lanka is one of the world’s biodiversity hotspots — a 65,000-square-kilometre island that has retained significant forest cover despite dense human settlement. It is also home to the Indian pangolin (Manis crassicaudata), a Critically Endangered species whose island population faces a distinct set of pressures: hunting for local use, road mortality, and habitat fragmentation between the wet and dry zones. Understanding the status of pangolins in Sri Lanka requires looking at both the species’ ecology and the specific social, legal, and institutional context of island conservation.

The Indian Pangolin in Sri Lanka

The Indian pangolin (Manis crassicaudata) is the only pangolin species found in Sri Lanka, and in fact the only one found on the entire Indian subcontinent. It is a large, ground-dwelling insectivore, typically weighing between 10 and 16 kg — larger than the African Temminck’s ground pangolin. Its scales are broader and fewer in number than those of the Asian species found further east, and it is adapted to a broad range of habitats: dry scrub forest, mixed deciduous forest, and secondary forest patches across both the wet and dry zones of the island.

In Sri Lanka, Indian pangolins have been documented across a wide geographic range — from the Northern Province through the North Central dry zone, into the Uva highlands and the wet zone forests of the southwest. Systematic camera-trap surveys across the country’s national park network have produced confirmed records in Wilpattu, Wasgomuwa, Minneriya, Lunugamvehera, and Udawalawe National Parks. Anecdotal records from plantation workers, farmers, and wildlife rangers suggest the species also persists in forest fragments and rubber, coconut, and tea estates, though population density there is unknown.

The IUCN Red List assessment classifies Manis crassicaudata as Vulnerable across its global range, but researchers working in Sri Lanka have argued that the island population warrants more precautionary treatment. Unlike India, where the species occupies a vast continental landmass, Sri Lanka’s pangolins exist in a geographically bounded, island population with no prospect of connectivity to mainland populations.

Threats Specific to the Island

Sri Lanka’s pangolin threats are different in character from those driving the crisis in Southeast Asia. There is no evidence of large-scale commercial export of pangolin products from Sri Lanka — the country lacks the overland transit infrastructure that makes mainland range states central to international trafficking routes. Instead, the primary threats are domestic.

Subsistence and opportunistic hunting is the most consistently documented threat. Pangolins are occasionally killed for bushmeat, particularly in rural communities near forested areas. Scales are used in some traditional Ayurvedic preparations, and there are reports of scales being sought for local superstition-based uses — including the belief that pangolin scales brought under the home ward off snakes. The market for these uses is small and localised, but significant relative to what is likely a small island population.

Road mortality is a growing concern documented by citizen science observers and the Road Kill Sri Lanka project. Pangolins are slow-moving, nocturnal, and have no effective response to vehicle approach. The rapid expansion of night-time road traffic on previously quiet rural roads — linked to tourism infrastructure development and resettlement following the end of the civil war in 2009 — has increased collision risk in areas like the Vavuniya–Mankulam highway and the Puttalam coast road that pass through prime pangolin habitat.

Habitat fragmentation is the structural background threat. Sri Lanka’s human population density of roughly 340 people per square kilometre is among the highest in Asia for a country of this size. Agricultural expansion, rubber estate rehabilitation, and suburban spread from Colombo into the Western Province have reduced the connectivity between forest fragments. Pangolins, with home ranges of several square kilometres per individual, need connected habitat to maintain viable breeding populations.

Electric fences erected to protect crops from elephant raids — a serious and long-standing human-wildlife conflict issue in Sri Lanka — also injure and kill pangolins. Field staff from the Department of Wildlife Conservation have recorded pangolin electrocutions, though systematic monitoring of this threat is absent.

Legal Protection and Enforcement

Sri Lanka’s legal framework is relatively strong on paper. The Fauna and Flora Protection Ordinance (FFPO), first enacted in 1937 and substantially amended in 2009, lists the Indian pangolin under Schedule I — the highest protection tier — making capture, killing, possession, and trade a criminal offence with penalties of up to five years’ imprisonment and fines. Sri Lanka is also a signatory to CITES and is a party to the Convention on Biological Diversity.

Enforcement quality varies substantially. Urban seizures — often triggered by tip-offs or social media posts of people photographed with live pangolins — do occur and sometimes lead to prosecution. Rural enforcement in remote dry-zone areas is more episodic. The Department of Wildlife Conservation operates ranger posts across most of the national park network, but the hinterland forests and plantation edges where pangolins are most vulnerable have less consistent coverage.

In recent years, the Sri Lanka Wildlife Conservation Society and several local NGOs have engaged the Department of Wildlife Conservation on specific pangolin awareness activities, including training programmes for provincial wildlife officers on pangolin identification and rescue protocols. The Biodiversity Sri Lanka programme and TRAFFIC South Asia have also produced intelligence on domestic trade, documenting occasional seizures of scales in Colombo markets and online sales.

Conservation Research and Monitoring

Systematic research on Sri Lankan pangolins is limited but growing. Camera-trap studies in multiple national parks have provided confirmation of presence and occasional images of foraging behaviour. Citizen science observations via iNaturalist have increased, with observations clustered around national park buffer zones and plantation forest fragments in the Knuckles Range and Rakwana Hills.

Population estimates for the Sri Lanka population do not exist at a national scale. Given the size of the island and the habitat available, the total population is unlikely to exceed a few thousand individuals — a small number for a geographically isolated group with no immigration from continental Asia. This makes the Sri Lanka population intrinsically more vulnerable to local threats than continental range state populations, even if threat intensity is lower.

Research priorities identified by herpetologists and mammalogists working in Sri Lanka include basic home range studies (none have been published using GPS tracking for Sri Lankan individuals), a national distribution survey using systematic camera-trap grids, and genetic sampling to determine whether the island population shows evidence of reduced diversity relative to Indian populations.

Cultural Context: Buddhism and Wildlife

Sri Lanka’s majority Buddhist culture provides a meaningful foundation for conservation messaging. Buddhist doctrine’s first precept — non-harm to living beings — has historically translated into public sympathy for wildlife protection. Unlike in some parts of mainland Asia where traditional medicine demand drives consumption, Sri Lanka’s dominant cultural framework does not include a tradition of systematic wildlife consumption for health or status signalling.

This makes community-based conservation messaging relatively tractable. Conservation organisations have used Buddhist temples and monks as trusted voices in rural communities to deliver messages about pangolin protection. The approach mirrors work done by organisations like the Wildlife Conservation Society in Buddhist-majority mainland countries, and has shown positive reception in pilot programmes in the Kurunegala and Matale districts.

Conservation Priorities for Sri Lanka

Given the island context, the most high-value conservation investments for Sri Lankan pangolins are:

1. National population survey — A systematic camera-trap grid across the dry zone and selected wet-zone forest patches would provide the first national-scale distribution and relative abundance estimate. This is the foundational data gap.
2. GPS telemetry study — A study of 10–20 individuals would establish home range size, habitat selection, and key movement corridors, enabling targeted road-kill mitigation and land-use planning inputs.
3. Electric fence mortality monitoring — A standardised protocol for rangers to record and report pangolin fence casualties would quantify this underappreciated threat.
4. Community messaging in buffer zones — Temple-based and school outreach in villages adjacent to dry-zone national parks, building on existing Buddhist precept messaging frameworks.
5. Online trade monitoring — Systematic monitoring of Sri Lankan social media and classifieds platforms for pangolin trade, coordinated with police wildlife crime units.

Sri Lanka is not on the front line of the global pangolin trafficking crisis in the same way that Cameroon, Vietnam, or Malaysia are. But its bounded island population makes it biologically significant, and the relatively tractable threat landscape makes well-targeted conservation investment unusually cost-effective. The Indian pangolin’s survival in Sri Lanka does not require transforming international criminal supply chains — it requires consistent domestic enforcement, targeted research, and community engagement in a country that already has the legal framework and cultural preconditions to support it.
