Scientific Name: Aloe cremnophila Reynolds & P.R.O.Bally

Assessment Information [top]

Red List Category & Criteria: Endangered D ver 3.1

This very narrow endemic occurs in an area that has seen much habitat deterioration in the past, but it is not certain if this has had any impact on the actual cliffs where this species grows. Given the low number of estimated mature individuals, Aloe cremnophila is listed as Endangered. If the threats are found to be more significant then it would qualify for listing as Critically Endangered.

Geographic Range [top]

Range Description:Known only from northern Somalia (endemic to Daloh and Mait escarpments near Erigavo between 2,000 and 2,133 m).

Population [top]

Population:A. cremnophila is a narrow endemic from the Daloh and Mait escarpment. Given the linear nature of it's habitat, (<7 kmĀ² area of occupancy) this amounts to a very small population estimated to number fewer than 250 mature individuals (S. Carter pers. comm.).
Current Population Trend:Unknown
Additional data:
Number of mature individuals:240
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Aloe cremnophila grows on cliff faces in Juniperus-Pistacia forest.

The main flowering period is not known.

Threats [top]

Major Threat(s): The main threat to this species is the erosion of the cliffs it grows on resulting from the deforestation of the Juniperus forest in the area (Thulin 1994).

Conservation Actions [top]

Conservation Actions: In cultivation at RBG Kew and seeds preserved in the Millennium Seed Bank Kew. At present this species is not covered by the protected area network.
