Conservation
Threats listed in assessment
This species is browsed by native grazers including gazelle and ibex, although they don't appear to be a threat to the vegetation (Ghazanfar and Fisher 1998). It is, however, also thought to be browsed by feral goats (Feulner 2011) which may pose a threat, as it is often seen to be heavily grazed (Feulner 2011). This species can grow to the size of a small tree, however, it is typically reduced to a cushion by browsers (Feulner 2016).
