Dynamics of illegal wildlife trade in Indonesian markets over two decades, illustrated by trade in Sunda Leopard Cats

ABSTRACTWildlife trade is recognised as an impediment to conservation. Yet, long-term trade data are lacking for many species, precluding analysis of trends and trade dynamics. The Sunda Leopard Cat is endemic to insular Southeast Asia, where despite legal protection, it is openly traded. Data from Java and Bali (1996–2018, 393 surveys, 219 cats recorded in 21 markets) reveal that numbers of cats decreased (1.95/survey in the 1990s, 0.44/survey in the 2010s) and their prevalence decreased (from 46% to 30% of surveys recording cats). Invariably in the animal markets other protected wildlife was for sale, even if Sunda Leopard Cats were not present. Corrected for inflation, prices were higher in recent years (US$59 vs US$26) and higher in markets with low availability, possibly indicating an Anthropogenic Allee Effect whereby a premium is paid for rare species. Direct comparisons between markets reveal a complicated pattern with evidence of a significant decrease from only one market, but clear shifts of th...
