by the South African National Biodiversity Institute (SANBI) in 2008; this was upheld again in 2009. They believe the total population numbers are decreasing. It grows in areas generally unsuitable for normal cultivation, and most habitat loss was thought to be fairly recent in 2008. Nonetheless, SANBI estimated that the 'historical' population had been reduced at least 30% based on a habitat loss of some 40%, primarily to agricultural development. This was especially caused by the recent success of the vineyards and olive orchards. SANBI estimated that with the continuing viability of these farms a further reduction of the population by 30% is likely by the year 2028. Other threats identified by SANBI are over-harvesting, pollution, invasive plants, natural disasters and changes in native species dynamics. Gallery References burchellii Flora of South Africa
