This species has been uplisted from Near Threatened following evidence that it is declining rapidly, owing to intensive trapping and the loss and degradation of its habitats. It is thus listed as Vulnerable. If further evidence suggests that the decline is more rapid than currently thought, the species may qualify for uplisting again in the near future.
