How Climate Change Is Shifting Pangolin Habitats Across Africa
Pangolins are among the most climate-sensitive large mammals in Africa and Asia. Their dependence on specific soil types for burrowing, particular ant and termite species for food, and moderate humidity for thermoregulation makes them acutely vulnerable to environmental shifts. As global temperatures rise and rainfall patterns become increasingly erratic, pangolin populations face a compounding crisis that adds ecological pressure to an animal already decimated by illegal wildlife trade.
Understanding how climate change affects pangolin habitats is critical for conservation planning. Rescue and rehabilitation programs, protected area management, and anti-poaching strategies must all account for a future in which the suitable habitat for these animals may shrink significantly, fragment further, or shift into regions where they historically have not occurred.
Temperature Stress and Thermoregulation Challenges
Pangolins are endothermic mammals, meaning they generate internal body heat, but their physiology is tuned to relatively narrow temperature ranges. Unlike larger megafauna that can tolerate a broader thermal envelope, pangolins rely on burrows to escape midday heat in savanna environments and on leaf litter or dense canopy in forest habitats to maintain comfortable body temperatures.
Research from sub-Saharan Africa indicates that the Temminck's ground pangolin (Smutsia temminckii), the species most common across South Africa, Zimbabwe, and Botswana, experiences thermal stress when ambient temperatures exceed 38 degrees Celsius for extended periods. As southern African summers grow hotter and longer under projected climate scenarios, suitable daytime refugia become more critical. Soil moisture affects burrow temperature; in drought conditions, shallow soils crack and lose insulating capacity, forcing pangolins either deeper underground — where they expend more energy excavating — or into open terrain where they are exposed to predation and thermal stress simultaneously.
Shifting Rainfall and Prey Availability
The pangolin's exclusive diet of ants and termites links it directly to insect population dynamics, which are themselves sensitive to rainfall timing and quantity. Both ant colonies and termite mounds require adequate moisture to sustain their populations. Prolonged drought reduces colony sizes, forces colonies deeper underground, and lowers the caloric density of foraging grounds available to pangolins.
Studies in the Limpopo region of South Africa have documented that pangolin home ranges expand markedly during drought years, with GPS-tagged individuals moving up to three times their normal distances in search of productive ant trails. Larger home ranges mean more fence crossings, more road crossings, and more encounters with people — all factors that increase mortality risk in a species whose populations are already fragmented.
In Central and West Africa, where forest pangolin species such as the white-bellied pangolin (Phataginus tricuspis) and the black-bellied pangolin (Phataginus tetradactyla) are found, the relationship between rainfall and prey is similarly important. Disruption of seasonal forest rainfall patterns alters both the timing and distribution of ant swarming events, which are key foraging windows. If swarms occur earlier or later than historical norms, pangolins may miss peak prey availability, compromising body condition before the dry season.
Habitat Contraction and Range Shifts
Species distribution models — mathematical tools that project where a species can survive based on climate variables — consistently show southward and upward (to higher altitude) range shifts for many African wildlife species under warming scenarios. For pangolins, this is complicated by the fact that suitable habitat is already highly fragmented due to agricultural expansion and fencing.
Climate models projecting conditions through 2050 and 2080 suggest that the core range of Temminck's ground pangolin may contract northward into wetter zones as southern savanna becomes drier, while simultaneously facing encroachment by farming at the more productive northern margins. The net result could be a significant reduction in accessible, connected habitat, even if total land area within the theoretical climate envelope remains similar.
Tree Pangolins and Forest Loss
The arboreal pangolin species of Central Africa face a distinct but equally severe threat from climate-linked habitat loss. Tropical forest dieback, driven by reduced rainfall and increased temperatures, removes the canopy layer that arboreal pangolins depend on for foraging, shelter, and escape from predators. Deforestation for agriculture accelerates this loss, and the combination of direct habitat destruction with climate-induced forest die-off creates a pincer effect on forest pangolin populations.
Even the giant ground pangolin (Smutsia gigantea), which inhabits forest-savanna mosaics across Central and West Africa, may find suitable habitat shrinking as the boundary between forest and savanna shifts under changing moisture regimes. These species are poorly studied, making it difficult to quantify the exact risk — but the directional trend is clear.
Human Land Use Amplifies Climate Stress
Climate change does not operate in isolation. It interacts with existing stressors to produce outcomes worse than either factor alone would generate. For pangolins, the critical amplifying factor is human land use. As agricultural frontiers expand into marginal lands — driven partly by climate-induced productivity losses in existing farmland — pangolin habitat shrinks at both ends. Farmers move into new land, and pangolin range contracts toward less disturbed areas, which are themselves being reduced by the same processes.
In South Africa, sugarcane expansion into KwaZulu-Natal and Mpumalanga lowveld has historically removed Temminck's ground pangolin habitat. Under future climate scenarios where suitable cane-growing areas shift southward, this pressure could extend into regions currently supporting viable pangolin populations in the Eastern Cape highland zones.
What Can Be Done
Conservation practitioners working with pangolins are adapting their strategies to account for climate-linked habitat change. Several interventions have emerged as priorities:
Habitat Corridor Creation
Linking existing protected areas through private land stewardship and wildlife easements allows pangolins to move in response to shifting conditions without crossing hostile terrain. In South Africa, the Wildlife Ranching Association and Endangered Wildlife Trust have both facilitated corridor negotiations on private land specifically aimed at maintaining connectivity for wide-ranging species including pangolins.
Prey Base Monitoring
Establishing baseline data on ant and termite population dynamics across pangolin habitat enables managers to detect early-warning signals of prey collapse before pangolin body condition deteriorates. This monitoring is relatively low-cost and can be incorporated into existing biodiversity surveys.
Translocation to Climate Refugia
Where existing populations face severe habitat degradation, assisted migration — moving individuals to identified climate refugia that will remain suitable under projected future conditions — is increasingly being discussed as a conservation tool. This is ethically complex and logistically challenging for a species as sensitive to capture stress as pangolins, but may become necessary for some subpopulations within the coming decades.
Community-Based Conservation
Local communities in rural South Africa, Zimbabwe, and Mozambique play a critical role in determining whether pangolins survive outside formal protected areas. Economic incentives linked to pangolin presence — through ecotourism, carbon credits, and biodiversity offsets — can make pangolin conservation financially competitive with agricultural land use, reducing the pressure to convert habitat.
The Road Ahead
Climate change is not the only threat pangolins face, but it is becoming an increasingly urgent one. A species that has survived unchanged for 80 million years now confronts environmental changes occurring on timescales of decades. The capacity of pangolins to adapt naturally is limited by their slow reproduction, specialised diet, and the fragmented state of their remaining habitat.
What we do in the next 20 years will determine whether pangolins can navigate the climate transition with sufficient habitat, connected ranges, and intact prey bases to sustain viable populations. The science is clear. The urgency is real. The conservation community is working — but the scale of the challenge demands broader societal and policy support to succeed.
