Ground Pangolin Home Range Size: What the Data Shows

Published 28 June 2026 • AlphaPanga Research Team • 8 min read

Among the many ecological facts that distinguish Temminck's ground pangolin (Smutsia temminckii) from other southern African mammals, one stands out for its conservation implications: these animals move across surprisingly large areas. A single individual may range over 5 to more than 30 square kilometres in the course of a year, crossing farm boundaries, roads, fencing lines and in some cases the outskirts of human settlements. Understanding the ground pangolin home range — what it is, how it is measured and what drives its size — is fundamental to any practical effort to protect this species in the South African landscape.

What Home Range Means in Ecology

In wildlife ecology, a home range is the area that an individual animal uses routinely in the course of its normal activities: foraging, sheltering, breeding and movement between resources. It is distinct from a territory, which implies active defence of an area against conspecifics. Most pangolin research uses home range rather than territory because pangolin space use, while individual, does not appear to involve the sustained aggressive defence that the territory concept requires.

Home range is not a fixed boundary. It is a statistical construct derived from location data, and it changes over time as an animal's requirements shift with season, reproductive state, prey availability and age. Ecologists typically report home range using either a minimum convex polygon (the smallest polygon that encloses all recorded locations) or a kernel density estimate, which weights areas by the intensity of use and can identify core areas within the broader range. Both methods depend on an adequate sample of location fixes collected over a sufficiently long period to capture the animal's full spatial behaviour.

What GPS Tracking Studies Reveal

Before GPS telemetry became practical for small-bodied, nocturnal wildlife, quantifying Temminck's pangolin territory size was extremely difficult. Radio-tracking provided general movement data, but the effort required to follow an animal through dense bush on foot at night limited sample sizes and precision. Modern GPS transmitters, fitted to a pangolin's tail scales using a lightweight non-invasive harness, record location fixes automatically at set intervals — typically every hour during active periods — and download data remotely or at close range. This approach has transformed the quality and quantity of ground pangolin home range data available to researchers.

Studies conducted in South Africa's Limpopo, North West and Mpumalanga provinces, as well as research in the Tuli Block region of Botswana and sites in Zimbabwe, collectively show that ground pangolins are genuinely wide-ranging animals. Individual ranges of 10 to 20 km² are common, and outliers above 30 km² have been recorded in animals tracked over full annual cycles. Even the lower end of the distribution — around 5 km² — represents an area far larger than most South African nature reserves dedicated primarily to pangolin protection.

Seasonal Variation in Range Use

Pangolin space use is not constant through the year. Seasonal shifts in prey availability, temperature and reproductive activity all drive changes in how much ground an individual covers. In summer, when ant and termite foraging is productive and food is relatively abundant across the landscape, pangolins may concentrate their activity in smaller core areas, reducing daily travel distances. In the dry winter months, when surface ant and termite activity declines and prey is less evenly distributed, individuals must search more widely to meet their nutritional needs, often extending their effective range.

Reproductive activity introduces further seasonal variation, particularly in males. The mating season for Temminck's pangolin in southern Africa is generally understood to peak in the second half of the year, and tracking data from multiple sites indicate that male movements expand significantly during this period as individuals range farther to locate receptive females. A male whose dry-season range centres around 15 km² may extend his movements to cover 25 km² or more during the peak breeding window.

Male versus Female Home Ranges

Male Temminck's pangolin territory size consistently exceeds that of females in studies where both sexes are tracked. This sexual difference in space use is common among solitary mammals and reflects the male's need to locate and access multiple females across the landscape. In practical terms, male ranges in southern African studies have frequently been recorded at roughly two to three times the area of female ranges in equivalent habitat. A female with a well-resourced 8 km² range may share her landscape with a male whose range encompasses hers and those of two or three neighbouring females.

Female ranges, though smaller, are not trivially sized. A breeding female in typical Limpopo bushveld commonly maintains a range of 8 to 15 km², sufficient to access diverse burrow networks and sustained ant and termite resources without exhausting prey in any single area. The female's range is likely to be more stable across seasons than a male's, anchored by preferred denning sites, particularly when she is rearing a dependent young animal.

Overlap with Farmland and Human Settlements

The scale of the ground pangolin home range has direct implications for where these animals spend their time and what threats they face. South Africa's formal protected area network, while extensive in total area, is fragmented. The private game reserves, national parks and provincial nature reserves where pangolin conservation efforts are concentrated rarely extend to 30 km² in a single contiguous block that would fully contain even one large male's range.

Tracking data from multiple study sites confirms that pangolins routinely cross onto commercial farmland, communal grazing areas and in some cases land adjacent to small rural settlements. On farmland, the risks include snares set for other species, vehicle strike on farm roads, electrocution on standard agricultural electric fencing, and encounters with domestic dogs. The pangolin's response to encountering a threat — curling into a ball and remaining motionless — is catastrophically ineffective against snares, which tighten with any resistance, and against dogs, which can persist in an attack far longer than wild predators. The overlap between pangolin habitat in South Africa and actively farmed land is therefore one of the most consequential factors in the species' vulnerability.

Human settlements present additional challenges. Pangolins approaching the outskirts of villages or peri-urban areas at night encounter artificial lighting that disrupts their sensory orientation, domestic animals, vehicle traffic and increased human presence. Camera trap data from conservation areas bordering communal land in Limpopo document individuals moving through these transition zones regularly, usually without incident but consistently exposed to risks that do not exist within protected area boundaries.

Conservation Implications of Large Home Ranges

The conservation significance of Temminck's pangolin territory size cannot be overstated. A species with a home range measured in tens of square kilometres cannot be protected by reserve boundaries alone. Each individual animal is, by ecological necessity, a landscape-scale conservation challenge.

This has practical consequences for how pangolin conservation in South Africa must be structured. Protected area management remains important, but it must be complemented by engagement with private landowners, communal land managers, provincial road authorities and rural communities across the entire landscape each animal uses. The African Pangolin Working Group's model of deploying conservation officers across a network of privately held land, training farmers to identify and report pangolin sightings and collisions, and fitting electric fence modifications that reduce electrocution risk is a direct response to the spatial reality of pangolin ecology.

Large home ranges also affect the feasibility of population monitoring. A species whose individuals are spread across large, partly inaccessible areas, and which is nocturnal and cryptic, is inherently difficult to survey using standard wildlife census methods. Camera trap grids, acoustic monitoring and mark-recapture approaches must be scaled to match actual range sizes to produce reliable population estimates. Underestimating how far individuals move leads to survey designs that miss animals and undercount populations.

How Range Size Affects Vulnerability to Poaching

A large home range increases a pangolin's exposure to poaching risk in two ways. First, the animal must traverse more land, crossing more fence lines, more roads and more areas of varying land tenure each night, multiplying the number of encounters it has with threats that cannot be predicted or managed in advance. Second, a wide-ranging animal is harder to monitor continuously. A pangolin that leaves a GPS-collared study area for several weeks in an extended seasonal excursion is outside the range of observer response if it is snared or confiscated.

Poachers who understand pangolin movement patterns exploit the predictability that comes with routine use of key landscape features such as watercourses, fence lines and territorial boundaries between males. Animals moving along predictable routes through unprotected farmland can be intercepted. The combination of a large range, partly unprotected landscape and a defensive behaviour that renders the animal immediately capturable once found means that each kilometre of unmonitored range represents genuine poaching exposure.

This is why GPS tracking is not only a research tool but an active conservation instrument. Rapid-response protocols triggered by unexpected transmitter inactivity allow field teams to investigate potential poaching events before animals can be moved far from their capture site. The data that defines the ground pangolin home range also, in real time, enables the intervention that keeps tracked individuals alive.

For anyone engaged in Temminck's pangolin habitat assessment, reintroduction planning or policy work on wildlife corridor design, the home range data accumulated across southern Africa in the past decade sends a consistent message: this species lives at a landscape scale, and conservation responses must match that scale.
