How bushmeat snaring intersects with pangolin mortality, and what removal teams are doing about it
Across sub-Saharan Africa, millions of wire snares are set each year in forests, savanna woodlands, and protected area buffer zones. Most are intended to catch duiker, warthog, porcupine, and other species for the bushmeat trade. But snares are indiscriminate. Any animal that moves along a trail or investigates a termite mound can be caught. For pangolins, this non-selectivity makes wire snaring one of the most significant and least-discussed mortality threats they face.
Unlike targeted poaching, where a poacher actively seeks a pangolin for its scales or meat, snare mortality is incidental -- a consequence of the pangolin being in the wrong place. The snare was not set for the pangolin. But the pangolin is dead regardless.
The Temminck's ground pangolin (Smutsia temminckii) and, in forested regions, the white-bellied pangolin (Phataginus tricuspis) and giant ground pangolin (Smutsia gigantea) all show behavioural patterns that make them vulnerable to wire snaring.
Pangolins follow well-defined foraging routes between established termite mounds and ant hills. They return to productive foraging sites repeatedly over weeks and months. Their movements are largely predictable at the landscape scale: low-lying corridors between foraging areas, paths along drainage lines, and access points around mound clusters. These are exactly the places where bushmeat trappers set snares.
When a pangolin encounters a snare, its defensive response compounds the problem. A pangolin's primary defence against predators is to roll into a tight ball, using its scales as armour. In the presence of a restraint it cannot see or escape, the curl reflex triggers rapidly. A curled pangolin wedges itself against the snare, allowing the wire to tighten with body pressure. Struggles to uncurl or move away increase tension. Animals may remain in this position for days before dying of blood loss, infection, dehydration, or predation while immobilised.
Snares used in African bushmeat hunting are typically constructed from twisted steel wire, copper electrical wire, or multi-strand cable removed from vehicle tyres. Wire gauge and loop diameter vary, but most snares set for medium-to-large bushmeat species produce a loop of 20-40 cm in diameter -- sized to catch an impala or duiker by the neck. Ground pangolins fall within this size category.
Placement strategies include:
Wire snaring is documented across the entire sub-Saharan pangolin range. Intensity is highest in areas where:
In southern Africa, the ground pangolin is the species most frequently caught in bushmeat snares due to its use of savanna and bushveld habitats where snaring is intense. In West and Central Africa, the white-bellied pangolin and black-bellied pangolin are caught in forest snare arrays. Giant ground pangolins, due to their lower population density, are caught less frequently in raw numbers but each incident represents a proportionally higher impact on a sparse population.
Veterinary examination of snared pangolins rescued alive documents a consistent injury spectrum. Wire entering between the scales produces lacerations that range from superficial skin cuts to deep tissue damage reaching bone. Limb snaring typically results in vascular compromise with tissue death distal to the constriction point. Tail snaring, which occurs when an animal's tail passes through a loop set at ground level, produces tail-tip amputations and ligature injuries.
Neck snaring -- the target zone for medium-sized bushmeat snares -- is almost invariably fatal in pangolins. The combination of the curl reflex, the weight of the armoured body bearing down on the wire, and the physiological stress response produces rapid deterioration. Animals discovered within hours of entanglement have been successfully treated, but the probability of recovery declines sharply with time in the snare.
Secondary infection at all wound sites is a major mortality driver. Pangolin skin, once penetrated through the scale line, is highly susceptible to bacterial infection. Wounds that would be manageable in other species can become septic rapidly in pangolins under the additional stress of captivity and veterinary handling.
Dedicated snare removal programmes have become a cornerstone of protected area management in snaring-intensive landscapes. The logic is straightforward: a snare removed from the bush is a threat eliminated. Each wire loop extracted represents a potential pangolin -- and hundreds of other species -- saved from an unseen death.
Effective snare removal programmes share several characteristics:
Snare removal addresses the immediate threat but does not eliminate it. Snares are re-set because the drivers of bushmeat hunting -- market demand, food insecurity, and the absence of alternative income -- persist. Long-term reduction in snaring pressure requires engagement with the communities from which trappers come.
Programmes that have demonstrated measurable reductions in snaring intensity over multi-year periods typically combine enforcement with community benefit. When communities receive tangible returns from wildlife -- through employment as rangers or trackers, through ecotourism revenue sharing, or through access to alternative protein sources -- the social calculus of bushmeat hunting changes.
In some landscapes, community-based natural resource management frameworks legally empower communities to manage wildlife on communal land, creating a direct stake in the survival of the animals their land supports. These models have shown success in southern Zimbabwe, parts of Zambia, and Namibia's communal conservancy system. Their transferability to higher-pressure contexts -- particularly in West and Central Africa where pangolin snaring is most intense -- remains an active area of programme development.
A pangolin discovered in a snare alive undergoes emergency field assessment by a trained ranger or veterinarian before removal. If the wire has not produced deep tissue damage and the animal is responsive, field removal with follow-up release is sometimes possible. More complex injuries require transport to a rehabilitation facility for surgical wound care, antibiotic treatment, and supportive nutrition before release.
Pangolins that survive snare injuries and subsequent rehabilitation often bear permanent disfigurement: shortened tails, missing scale segments, healed but visibly scarred limbs. Their survival and successful return to the wild represents a conservation outcome worth tracking, and post-release monitoring of rehabilitated snare survivors contributes to understanding long-term impacts on individual fitness and breeding success.
Wire snares are one of the most significant non-targeted threats to African pangolins. Set for bushmeat species in general, they catch pangolins whose foraging routes and termite mound use patterns intersect with snare lines. The pangolin's defensive curl behaviour worsens entanglement. Snare removal programmes in southern and East Africa remove hundreds of thousands of snares annually, but the pace of re-setting in high-pressure areas requires sustained patrol effort. Community benefit mechanisms that reduce the incentive to snare offer the most durable long-term solution.
Wire snares are set as loop traps along animal trails and around termite mounds and ant hills that pangolins regularly visit. A pangolin walks through the loop, which tightens as the animal tries to move forward. The defensive rolling response causes snares to cut deeply into the neck, limbs, or tail, often resulting in severe injuries or death before the trapper returns.
Wire snares set to catch protected species are illegal in most African countries. However, snares are widely used and rarely result in prosecution due to enforcement challenges in remote areas. Some jurisdictions tolerate limited snaring of specific non-protected species for subsistence, creating grey areas that commercial bushmeat operators exploit.
Removal data vary by country and protected area. In Zimbabwe's Hwange National Park, teams have removed tens of thousands of snares annually. In Zambia's Kafue National Park, coordinated operations collect over 100,000 snares per year in high-pressure zones. Each snare removed eliminates a threat that would remain active for years.
Wire snares cause lacerations through scale joints into tissue, partial or complete limb and tail injuries, neck ligatures that can cause strangulation, and wound infections. Mortality rates for snared pangolins in the wild are very high due to infection and blood loss before discovery.
