Justification
A. vossii was formerly listed as critically rare (Hilton-Taylor 1996, Hilton-Taylor and Smith 1994) and Endangered (Victor 2002). This is also one of few Aloe species listed on CITES appendix 1 as being threatened with extinction and requiring regulation of trade. However, current opinion on this species is that it is probably not as rare as was thought in the past and furthermore that it is probably not distinct from the widespread A. verecunda (status LC). However, until the taxonomy can be resolved - the concept of A. vossii might be retained as a variant of A. verecunda - this taxon is kept on the Red List As Data Deficient. Past threats to this species are also being mitigated largely due to many private landowners in the Soutpansberg converting their land to nature conservancies and it may become possible that the status of this taxon may be changed to Least Concern in future.
Distribution
Endemism
South African endemic
Provincial distribution

Range
Soutpansberg.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Grassland
Description
Rocky areas in mistbelt grassland. Altitude 1500-1700 m.
Threats
Willis and Willis (1995) mention bush encroachment of the grassland habitat by indigenous vegetation, alien invasive encroachment, too frequent fires and trampling by livestock as potential threats to A. vossii. Too frequent fires prohibits the growth of mature individuals as well as the establishment of seedlings (Willis and Willis 1995) and promotes the encroachment of the habitat by bracken fern (Craib 2005). Parts of the habitat has also been converted to timber plantations in the past (Craib 2005). According to Craib (2005) many landowners on the Soutpansberg have recently been persuaded to convert their land to private nature conservancies, and this is likely to prevent further serious declines in A. vossii subpopulations.

Notes
Its relationship to the Aloe verecunda complex should be readdressed. (P.J.D Winter pers. comm.) According to Craib (2005) variability within A. vossii and the closely related A. verecunda often leads to plants of the two species being virtually indistinguishable. Craib (2005) believes that A. vossii could only be considered as an ecotype or variant of A. verecunda. A. vossii is one of the few species of South African Aloes listed on CITES Appendix 1.
