Justification | A population reduction of >80% is estimated based on >90% habitat loss to wheat cultivation in the past 60 years (generation length 30 years). Ninety plants remain at a single location in a drainage line between cultivated fields (EOO and AOO 500 m²) and are declining due to alien grass invasion and a lack of fire. |
