Pangolin

Pangolin scales are composed entirely of keratin — the same structural protein found in human fingernails, hair and rhino horn — and have no scientifically proven medicinal properties. Despite this, they command high prices in traditional Chinese and Vietnamese medicine, where they are claimed to treat conditions from poor circulation to lactation problems. Scales are typically dried, roasted and ground into powder. Demand has been driven by rising middle-class incomes in China and Vietnam, which turned luxury wildlife products — including pangolin meat in high-end restaurants — into aspirational goods. Consumer-awareness campaigns and tighter law have begun to shift attitudes, and in 2020 China removed pangolin scales from the approved ingredient list of its official pharmacopoeia, but enforcement remains inconsistent.

As Asian pangolin populations collapsed, criminal networks pivoted to Africa. The two African ground pangolins (Temminck's in East and Southern Africa, and the giant ground pangolin in Central Africa) and the two tree-dwelling species in West and Central Africa are now poached at industrial scale and shipped to Asia. Nigeria, Cameroon, the Democratic Republic of Congo and East African ports appear repeatedly in major seizure records. The Africa-to-Asia trade typically runs through multiple transshipment points, using shipping containers and falsified customs paperwork, and individual multi-tonne scale seizures have been recorded.

Pangolins are notoriously hard to keep alive in captivity. They are specialist feeders dependent on particular ant and termite species, and they are easily stressed by handling and unnatural environments — leaving them prone to respiratory infection and digestive failure. A handful of programs have bred pangolins (a Sunda population to a third generation, and Chinese pangolins at zoos in Taipei and Prague), but none has yet bred and released animals back to the wild at meaningful scale. Rehabilitation can succeed when animals arrive in good condition and are held in semi-wild enclosures with natural forage, but success rates stay low. Prevention — stopping poaching before it happens — is the most effective intervention, which is why WARN concentrates on anti-poaching patrol support, community reporting and faster seizure response.

Pangolins live across Asia and sub-Saharan Africa. The four Asian species range through South and Southeast Asia and southern China: the Chinese pangolin across southern China and the eastern Himalayas, the Sunda pangolin through mainland Southeast Asia and the Greater Sunda islands, the Indian pangolin across the subcontinent, and the Philippine pangolin only on Palawan. The four African species occupy forests and savannahs from West Africa to Southern Africa. Some, like the two Smutsia ground pangolins, are terrestrial burrowers; others, like the white-bellied and black-bellied pangolins, are arboreal and use a prehensile tail to climb.
