Justification | Zaluzianskya marlothii is a Roggeveld endemic known only from one location. It has an extent of occurrence (EOO) of 8.5 km². This species has lost habitat to crop cultivation and the remaining habitat is experiencing ongoing degradation as a result of livestock overgrazing and drought. It therefore qualifies as Critically Endangered under criterion B1ab(iii)+2ab(iii). |
