Between the 1960s and 1970s, jaguars were heavily hunted, with as many as 18,000 killed every year to feed the trade in their skins. In 1975, the trade in jaguar hides was halted thanks to CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora), and populations began to stabilize. This week marks the 50th Anniversary of CITES and the 10th edition of World Wildlife Day, whose theme this year celebrates the power of Partnerships for Wildlife Conservation.
