Family | HYACINTHACEAE |
Synonyms | Resnova lachenalioides (Baker) Van der Merwe, Scilla lachenalioides Baker |
National Status |
Status and Criteria | Vulnerable A2c; B2ab(ii,iii) |
Assessment Date | 2022/05/13 |
Assessor(s) | H. Mtshali, A.J. Hankey & J.E. Victor |
Justification | This habitat specialist occurs only in marshy mistbelt grasslands and has an area of occupancy (AOO) of 68 km². It is known from 6-10 locations. The habitat continues to decline due to grazing, spreading alien invasive plants, and inappropriate fire management. A population reduction of 30% is inferred from historical habitat loss over three generations (generation length 20-30 years). Therefore, this species qualifies for a Vulnerable listing under criteria A and B. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Eastern Cape, KwaZulu-Natal |
Range | This species is recorded from the southern foothills of the Drakensberg, from Giant's Castle through southern KwaZulu-Natal to Umtata in the Eastern Cape. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Drakensberg Foothill Moist Grassland |
Description | It occurs in moist or marshy mistbelt grassland, sometimes on rock ledges, at 600-1800 m.a.s.l. |
Threats |
| About 44% of this species' habitat has been modified. Many subpopulations are known through historical records and are likely to be extinct due to habitat loss to timber plantations and expanding development. Parts of this species' range continue to decline due to grazing and inappropriate fire management. Spreading, unmanaged alien invasive plants, particularly in areas near timber plantations, are also causing ongoing habitat degradation. |
Population |
This species is locally common after fire. The population trend and size are currently unknown but are likely to be declining due to habitat degradation. A population reduction of 30% is inferred from historical habitat loss over three generations (generation length 20-30 years). Monitoring of the remaining subpopulations is required.
