Pangolin Threats: Habitat Loss and Land Use

When people think of threats facing pangolins, poaching and the illegal wildlife trade come to mind first. That association is warranted — pangolins are among the most trafficked mammals on earth. Yet habitat loss is an equally serious and often underestimated pressure acting on all eight pangolin species. Across sub-Saharan Africa and Southeast Asia, the landscapes pangolins depend on are being cleared, fragmented, and degraded at a pace that quietly erodes populations before any trafficker gets involved.

Understanding habitat loss as a threat requires looking at the land-use forces driving it: industrial agriculture, commercial logging, extractive industries, and infrastructure expansion. Each of these transforms wild landscapes in ways that leave pangolins with less food, fewer refuges, and less room to move.

Deforestation in Southeast Asia

Southeast Asia holds some of the highest concentrations of Sunda pangolins (Manis javanica) and Philippine pangolins (Manis culionensis), both critically endangered. The forests these species inhabit have been shrinking for decades, driven largely by the expansion of oil palm and the continued demand for timber.

Palm oil plantations now cover millions of hectares across Borneo, Sumatra, and the Malay Peninsula. Conversion of lowland and peat-swamp forest for oil palm removes the dense, structurally complex habitat pangolins rely on for shelter and foraging. Pangolins are specialist feeders — they target specific ant and termite colonies, and their foraging routes can span several kilometres each night. A monoculture plantation offers almost none of the insect diversity found in intact forest.

Commercial logging compounds the problem. Even selective logging, which leaves some trees standing, opens the forest canopy, alters soil moisture, and disrupts the microhabitats where termites and ants nest. Logged forests support far fewer colonies of the species pangolins prefer to eat. Secondary growth that follows logging provides patchy and unpredictable food resources, particularly during the years immediately after disturbance.

Agricultural Expansion in Africa

In Africa, the situation mirrors Southeast Asia in several respects, though the dominant land-use drivers differ. Subsistence and commercial farming are the primary forces converting bush and woodland into cultivated land. As smallholder farms expand and large-scale agricultural operations push into previously uncultivated areas, pangolin territories are steadily reduced and broken apart.

The African pangolins most affected include the white-bellied pangolin (Phataginus tricuspis) in forest-savanna transition zones and the giant pangolin (Smutsia gigantea) in riverine forests and moist woodland. Both species depend on undisturbed patches of natural vegetation large enough to sustain viable insect colonies year-round. When those patches are converted to maize or cassava fields, the food base disappears along with the habitat.

Agricultural expansion also introduces new mortality risks. Pangolins moving through a patchwork of farms and bush fragments encounter more people, more domestic dogs, and more snares set for bushmeat. Habitat loss and hunting pressure are not independent — they interact and amplify each other.

Mining and Infrastructure Development

Mining operations — whether for coal, iron ore, gold, or rare earth minerals — cause acute, localised destruction of pangolin habitat. Open-cast mining removes surface vegetation entirely, renders soil uninhabitable, and generates pollution that spreads into surrounding ecosystems. The access roads that accompany mining projects are often more damaging in the long run than the extraction sites themselves, as they open previously remote areas to hunting and further land clearing.

Infrastructure development — roads, railways, powerline corridors, and urban expansion — creates linear barriers across the landscape. These features physically divide habitat into smaller units and generate traffic that pangolins cannot navigate safely. A pangolin crossing a busy road between two patches of suitable habitat faces a high probability of being struck by a vehicle. Road mortality is a documented cause of death for several pangolin species and represents a significant but poorly quantified drain on local populations.

Habitat Fragmentation and Population Isolation

Perhaps the most insidious consequence of habitat loss is fragmentation — the process by which large, continuous areas of natural land are reduced to smaller, disconnected patches. For pangolins, fragmentation is particularly damaging because of their low reproductive rates. A female pangolin typically produces only one pup per year. Populations cannot recover quickly from losses, and small isolated populations are vulnerable to local extinction through inbreeding and random demographic events.

When patches of habitat become too small or too isolated, pangolins can no longer disperse between them. Young animals leaving their mothers' home ranges cannot find unoccupied territory. Genetic diversity declines over generations. The population becomes a statistical liability — still present, but unable to sustain itself over the long term without intervention.

Loss of Food Sources

Pangolins are obligate myrmecophages — they eat almost exclusively ants and termites. This dietary specialisation means they are exquisitely sensitive to changes in insect availability. When land is converted, the ant and termite communities that pangolins depend on are destroyed. Even partial habitat degradation can reduce insect density to levels that cannot support a pangolin's energy requirements.

In agricultural landscapes, the use of pesticides and soil fumigants further reduces insect populations. Termite mounds, which take years to establish and represent concentrated, reliable food sources, are routinely destroyed during land preparation for crops. Once a mound is destroyed, that food resource is gone for years. A pangolin that loses access to a substantial portion of its foraging territory may simply not find enough to eat.

The Ground Pangolin in South Africa

The ground pangolin (Smutsia temminckii) is the only pangolin species found in South Africa and is listed as Vulnerable on the IUCN Red List. It inhabits savanna and bushveld — open, arid to semi-arid landscapes with scattered trees and shrubs. These habitats are increasingly under pressure from agricultural intensification, game farming that favours vegetation clearing, and suburban expansion on the edges of cities like Pretoria, Johannesburg, and Polokwane.

Ground pangolins range over very large home ranges — sometimes exceeding 20 square kilometres for males. They require undisturbed ground with healthy termite and ant colonies accessible across a wide area. As bushveld is converted to cropland or subdivided for small-scale livestock grazing, the viable habitat available to individual pangolins shrinks. Road mortality on rural roads crossing their ranges is a recurring cause of death recorded by wildlife rehabilitation centres and researchers across the Limpopo, North West, and Mpumalanga provinces.

Conservation Corridors and Landscape Connectivity

The most effective landscape-scale response to fragmentation is the establishment of conservation corridors — strips or networks of natural habitat that reconnect isolated patches. Corridors allow pangolins and other wildlife to disperse, find mates, and recolonise areas from which they have been lost. In southern Africa, several landscape initiatives are working to maintain connectivity across communal and private land between formal protected areas.

Transfrontier conservation areas, such as the Greater Limpopo Transfrontier Park, create large-scale connected landscapes that benefit wide-ranging species like ground pangolins. At a smaller scale, corridors between private game reserves and communal wildlife areas can provide meaningful connectivity across agricultural matrices.

Community conservation areas and conservancies are proving to be important habitat anchors in regions where formal protected areas are sparse. When communities derive tangible benefit from wildlife on their land — through ecotourism, conservation employment, or carbon credit schemes — they have meaningful incentive to maintain natural vegetation rather than converting it.

What Landowners Can Do

Private landowners, farmers, and game reserve managers in pangolin range areas can take practical steps to reduce habitat loss impacts on their properties.

• Retain natural vegetation on steep slopes, drainage lines, and rocky outcrops where agriculture is impractical. These areas serve as refuges and movement corridors.
• Avoid the use of broad-spectrum pesticides and soil fumigants near natural vegetation patches. Insect diversity is directly linked to pangolin food availability.
• Protect termite mounds on the property. Mounds are long-term ecological assets and active removal destroys food resources that take years to re-establish.
• Install wildlife-friendly fencing where possible, or create deliberate gaps in existing fences at ground level to allow pangolins to pass through without being trapped or injured.
• Reduce vehicle speeds on farm and game reserve roads at night, when ground pangolins are most active and most likely to be struck.
• Register properties with local conservancy networks so that habitat patches are mapped and considered in regional land-use planning.

The Broader Picture

Habitat loss operates more slowly and less visibly than poaching, but its consequences are just as permanent. A landscape that has been cleared cannot support pangolins, regardless of how strictly anti-poaching laws are enforced. Protecting pangolins over the long term means protecting and restoring the land they live on — a task that involves farmers, landowners, planners, and governments alongside wildlife authorities and conservation organisations.

The good news is that habitat, unlike poached pangolins, can be recovered. Degraded land can regenerate. Fragmented patches can be reconnected. With the right land-use decisions, pangolin habitat lost over the past decades can be rebuilt — but the window for doing so is narrowing as conversion continues across Africa and Asia.
