Vulnerable B1ab(i,ii,iii,iv,v)
Assessment Date
2015/12/14
Assessor(s)
L. von Staden
Justification
EOO 2088 km², and six known locations. This species continues to decline due to ongoing habitat loss and degradation.
Distribution
Endemism
South African endemic
Provincial distribution
Western Cape
Range
Breede River Valley between Tulbagh and Worcester and eastwards to Touwsrivier and Karoopoort.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Breede Shale Renosterveld, Matjiesfontein Shale Renosterveld, Robertson Karoo
Description
Stony clay soils in renosterveld.
Threats
Critically little of this species' lowland renosterveld remains within the Breede River Valley, predominantly due to loss to agricultural expansion. Known subpopulations occur on isolated remnants, and continue to decline, particularly due to development around Worcester. Around Touwsrivier and Karoopoort, lowland renosterveld is extensively degraded due to overgrazing, and have also been ploughed in places. Drosanthemum species are highly palatable and decline rapidly in overgrazed areas.
