The pet and skin trades pose little threat to reptile species: new research
The reptile trade looks like an obvious threat, but the data say otherwise for most species. Between 2000 and 2020, more than 70 million reptile skins were traded, yet they came from fewer than 50 of the 10,000-plus known reptile species, mostly crocodiles, snakes and lizards. Wild populations of these heavily traded species still look healthy, probably because they are generalists that thrive in many habitats and breed fast, and are managed under quotas and monitoring. The pet trade is similar: price lists covering 340,000 live reptiles and amphibians were dominated by kingsnakes, corn snakes, pythons, bearded dragons and leopard geckos, which mostly come from captive breeding. The exceptions are island-restricted or slow-growing species.
Species that tolerate many habitats and reproduce quickly can absorb harvesting, especially when captive breeding supplies the market and quotas cap wild take. Slow-growing or island species lack that buffer.
Habitat loss, disease, invasive species and climate change drive most reptile declines, so focusing outrage on legal trade can misdirect conservation effort. Illegal smuggling still harms rare species, and targeted enforcement matters most for the few vulnerable ones.
Bearded dragons, among the most popular pet lizards worldwide, are native to Australia, which banned the export of its native wildlife decades ago, so pets abroad descend from captive breeding.
