Scientific Name | Cyrtanthus guthrieae L.Bolus |
Higher Classification | Monocotyledons |
Family | AMARYLLIDACEAE |
Common Names | Berg Lily (e), Berglelie (a), Brandlelie (a), Bredasdorp Lily (e), Bredasdorplelie (a), Bredasdorp-Lily (e) |
National Status |
Status and Criteria | Critically Endangered C2a(i) |
Assessment Date | 2011/09/26 |
Assessor(s) | D.A. Snijman, C. McMaster & D. Raimondo |
Justification | Extremely localized distribution in the Bredasdorp district, known from three locations (EOO 6 km²) and fewer than 250 mature individuals. Subpopulations are very small, consisting of around 10 mature individuals. This species has lost habitat to ploughing and its habitat continues to be degraded by trampling and grazing by livestock, and alien invasive plants. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Bredasdorp. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Overberg Sandstone Fynbos |
Description | Well-drained, sandstone mountain slopes. |
Threats |
| Much of this species' habitat on the lower slopes of the Heuningberg has been transformed for crop cultivation, with much of this agricultural expansion occurring in the past 10-15 years. Remaining subpopulations are threatened by severe overgrazing, as well as the uncontrolled spread of alien invasive plants. |
Population |
Observations of three subpopulations recorded no more than 11 plants in flower per subpopulation.
|
Population trend | Decreasing |
Notes |
| This species is not dependent on fire to flower, although it does flower in profusion following summer fires. The habitat is vulnerable to trampling by livestock (Duncan 2003). |
