Justification:
Due to high levels of exploitation, and loss of habitat and habitat quality as a result of political unrest and expanding human activities, this subspecies is estimated to have experienced a significant population reduction in the past 20-30 years (one generation is estimated to be 20 years), and it is suspected that this reduction will continue for the next 30-40 years. The maximum population reduction over a three-generation (60-year) period from the 1970s to 2030 is suspected to exceed 50%, hence qualifying this taxon for Endangered under criterion A4. The causes of the reduction, although largely understood, have certainly not ceased and are not easily reversible. The suspected future continuation of the population reduction is based on a precautionary approach taking into account the rapidly increasing human population density in the region and the high degree of political instability in the range states.
