This species was uplisted from Near Threatened to Vulnerable in 2013 following evidence that it is declining rapidly, owing to intensive trapping and the loss and degradation of its habitats. If further evidence suggests that the decline is more rapid than currently thought, the species may qualify for uplisting again in the near future.
