Population justification: A preliminary population estimate of fewer than 10,000 mature individuals is used here, but this requires further documentation.
Trend justification: Intense pressures on habitat are suspected to have driven rapid declines in the past. The rate of decline may begin to slow in the future as the few remaining habitat patches are increasingly confined to protected areas.
