Global seizures of tigers and tiger parts have averaged 150 of the big cats a year over the past 23 years, according to a new report, underlining the pressures facing an animal that is severely endangered in the wild despite continuing conservation efforts.The seizures took place in 50 countries and territories, but the vast majority were in the 13 countries where tigers can still be found in the wild.TRAFFIC’s latest report said it had identified at least 675 Facebook profiles in six Southeast Asian nations that were involved in the illegal trade and that three-quarters were from Vietnam.It also noted links between accounts involved in the illegal sale of tigers and tiger parts with those offering products made from ivory, bear parts and rhino horn.Given the persistence of the illegal trade, the conservation group urged countries to make law enforcement more effective by using intelligence-driven investigations to dismantle criminal networks along the entire chain, and ensure “strong and predictable” prosecution to deter traffickers who stand to make considerable sums from the trade."
