The report, released by the University of Oxford Wildlife Conservation Research Unit (WildCRU) and World Animal Protection, said that between 2010 and 2014, more than 64,000 live wild animals were officially reported as seized by wildlife enforcement agencies according to the Convention on International Trade in Endangered Species of Wild Flora and Fauna (CITES) trade database.
However, experts said that despite having the figures, the ultimate fate of seized live wild animals on whether they have "re-entered" the wildlife trafficking industry or have been rehabilitated remained "unknown" and hence "untraceable".
Researchers warn that these animals are likely to be only a fraction of actual seizures, as the study found only one in three (30 per cent) of countries that are parties to CITES provided any information.
"Two out of three countries did not report any live wildlife seizures, despite poaching of endangered species to supply the illicit global wildlife trade being estimated to be worth between USD 8-10 billion per year," the statement said.

"Illegal wildlife trade in Asia is a growing concern but reporting by India of live wild animals confiscated by enforcement agencies in the CITES trade database is virtually non-existent.
"We strongly urge the CITES trade database to include information on the fate of all live wild animal seizures, so we know what happens to these animals, and we can reduce the risk of them re-entering the illegal wildlife trade," WAP India Country Director Gajender K Sharma said.
Noting that the ultimate fate of seized live wild animals
"We fear this staggering number is just the tip of the iceberg. Only a relatively small proportion of wild animals involved with illegal trade are thought to be intercepted and reported by enforcement agencies - confiscation records were completely missing for 70 per cent of countries party to CITES. Given the rapidly growing global trends in illegal wildlife trade activity, it is highly unlikely that no live wildlife seizures were made on their borders," said Professor David Macdonald, a senior researcher on the study.
"The records that were provided show that around 20 per cent of all live wild animals reported as seized are currently considered to be threatened by extinction.
"We strongly recommend that the CITES trade database should include information on the fate of all live wild animal seizures, so we know what happens to these animals and we can reduce the risk of them re-entering the illegal wildlife trade," Macdonald said.
"Improved data recording is critical to knowing what happens to each animal and can help in looking at the challenges and issues enforcement agencies face in managing animals after seizure.
"Without this transparency, there's a real possibility that endangered species may be put back into the hands of the same criminals whom they were taken from. We need to be able to account for these wild animals.
