Description
Saline quartz patches.
Threats
This species is potentially threatened by infrastructure development and other construction associated with a road bisecting part of the population. This species is also highly sought-after in the specialist succulent trade, and is difficult to grow from seed. It is potentially threatened by collectors removing mature individuals from the wild.
Population

Bulbine bruynsii is a localized habitat specialist, known from a single subpopulation. A 2014 survey of the population recorded more than 2000 mature individuals, scattered in small clumps across 12 quartz patches. Five of these patches border on a road where it is potentially threatened by construction of a pipeline, but upon recommendation of the botanical specialist contracted for the survey, construction will be aligned with the road so as to avoid impacting the population. More than 50% of the surveyed population occur away from roads and other infrastructure, and is not threatened.
