Justification | A population reduction of at least 50% is estimated based on habitat loss and degradation by ostrich farming and crop cultivation in the past 20 years (generation length ± 10 years). EOO 250 km², AOO 13 km², two remaining locations continue to decline due to ongoing habitat degradation. |
