Higher Classification | Monocotyledons |
Family | HYACINTHACEAE |
National Status |
Status and Criteria | Vulnerable B1ab(iii)+2ab(iii) |
Assessment Date | 2014/04/02 |
Assessor(s) | L. von Staden & A.P. Dold |
Justification | A rare and localized species (EOO 1362 km²), estimated to occur at between five and 10 locations and declining due to ongoing habitat loss. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Eastern Cape |
Range | Port Elizabeth to Grahamstown. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Sundays Valley Thicket, Saltaire Karroid Thicket, Nanaga Savanna Thicket, Grass Ridge Bontveld |
Description | Sandy soils at low altitude, 0-300 m. |
Threats |
All three known subpopulations occur within protected areas, and are not threatened (A.P. Dold pers. comm. 2013). Similar thicket habitat within its known range is already at least 35% irreversibly modified, predominantly for crop cultivation, as well as urban expansion around Port Elizabeth, and loss is likely to continue. Subpopulations outside of protected areas are likely to be threatened and declining due to ongoing habitat loss. |
Population |
Subpopulations are small, and this species is currently known from only a few records, all of them in protected areas (MartÃnez-AzorÃn et al. 2011). It is cryptic and easily overlooked, and likely to be more common than records indicate (A.P. Dold pers. comm. 2014). Until its recent discovery, the species was however never collected before (MartÃnez-AzorÃn et al. 2011), even though its known range is botanically well-explored. It is therefore suspected to be fairly rare, occurring at less than 10 locations, but more field surveys are needed to confirm the precise size and extent of the population.
