In September 2014 two conservation organisations announced that a camera trap survey of seven sites in the three separate habitats from 2010 to 2013 had produced an estimate of the surviving population from 250 to 340 healthy individuals, with a few additional isolated small pockets probable. According to the report, the decline meant that the species might have to be moved to the "Critically Endangered" category in the IUCN list. As of 2019, poaching and the depletion of prey has caused the number of tigers in Belum-Temengor Forest Reserve to decline about 60% over a period of 7–8 years, from approximately 60 to 23.
