Traffic, a wildlife watchdog, reckons around 2,500 elephants must have died to produce so much ivory. This year could be worse. More than 200 elephants were killed in a single state of Cameroon in the first six weeks of 2012.
This threatens to return African elephants to the crisis times of the 1970s and 1980s, when poaching was rampant and extinction loomed for many populations. This led to an ivory trade ban, in 1989, and in turn to a collapse in demand for ivory. Elephant populations have since recovered. Yet the effects of the ban seem to be wearing thin, especially in east, west and central Africa, where wildlife protection is generally weak and the poaching heaviest.
Illegally gathered ivory typically leaves Africa from Kenya or Tanzania in shipping containers. It often passes through Malaysia, where forged papers disguise its origins. Most is then dispatched to China or Japan. Some tusks also pass through the bazaars of Cairo, where Chinese traders are the biggest buyers
China is the biggest recipient of poached African ivory; and the country's demand for the stuff is surging. A study of two Chinese cities for Traffic, by Esmond Martin and Lucy Vigne, concluded that since 2004 the number of ivory items for sale there had grown by 50%.
Some ivory can be traded legally, for example when the elephant that grew it died of natural causes or was shot to protect people or crops. Some African countries have stocks that predate the ban, which they can also sell. Such legal ivory sells for around $900 a kilogram in China's wholesale market, with the average tusk weighing between five and nine kilograms. A cheaper sort comes from extinct woolly mammoths, which are periodically excavated from Siberia's tundra. Read the full report here.
