Population [top]

Population: A serious decline in the population has reduced the numbers to less than 200 individuals. There is no recruitment and the older plants are dying.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: Growing up to 10 m, this aloe is largely confined to an intensely hot and arid area. It has been suggested that this species, along with A. dichotoma and Pachypodium namaquanum, represents a keystone in the ecosystem, being one of the few perennial plants able to tolerate the conditions. It is an important source of shelter, nectar, food and moisture, especially to the avifauna.
Systems: Terrestrial

Threats [top]

Major Threat(s): There is evidence of baboons and porcupines gnawing the stems in up to a third of the population. The impact of goats, donkeys and plant collectors may also be detrimental.

Conservation Actions [top]

Conservation Actions: The species is listed in CITES Appendix I.
