Listed as Vulnerable as the subspecies has a very restricted distribution on Perentian Besar Island. There are no major threats currently on the island, and the subspecies is unlikely to be susceptible to hunting. However, given its very restricted range and the fact that the island is relatively flat, it is likely to be very susceptible to other possible stochastic threatening processes. It may actually warrant listing in a higher category of threat if the population is shown to be declining, but further survey work is needed to confirm this.
