Washington: At least one in five species of birds, mammals, amphibians, and reptiles on Earth are bought and sold on the wildlife market — a number 40-60 per cent higher than previous recorded estimates, according to a study published in the journal Science. The researchers, including those from the University of Florida in the US, also developed a model to predict which species that aren’t traded now would likely be traded in the future.

The tool could help traditionally reactive wildlife managers become more proactive, they said. The trade of wildlife as pets or for animal products, such as horns, ivory, medicines or meat, is a multi-billion-dollar industry, the researchers said.

It is also widely recognised as one of the most severe threats to plants and animals, they said. However, the extent and impact of wildlife trade on global biodiversity across the animal kingdom remains poorly understood.

“The high demand for wildlife products and pets has driven pronounced losses in enigmatic species such as tigers, elephants, rhinos, and poison dart frogs,” the researchers said. “Some subspecies are already extinct e.g., the last Javan rhino, Rhinoceros sondaicus annamiticus, was shot for its horn in 2010 in Vietnam, or on the cusp of extinction in the wild, e.g., Bali myna, Leucopsar rothschildi — all because of trade,” they said.

The team evaluated the effects of wildlife trade across 31,745 terrestrial bird, mammal, amphibian and reptile species using data from the Convention on International Trade in Endangered Species of Wild Flora and Fauna (CITES) and data from the International Union for Conservation of Nature (IUCN) Red List. The researchers found that 5,579 animals, or roughly 18 per cent of the total vertebrate species included in their analysis, are currently being traded globally.
