Justification
Listed as Near Threatened as the species is thought to have undergone a reduction of 20-25% over the past 24 years (assuming a generation length of 8 years) due primarily to a decline in area and quality of habitat within the known range of the species and due to known levels of exploitation. Almost qualifies as threatened under criterion A2cd.
