Family | IRIDACEAE |
Synonyms | Homeria rogersii L.Bolus |
National Status |
Status and Criteria | Least Concern |
Assessment Date | 2016/11/19 |
Assessor(s) | D. Raimondo |
Justification | Moraea crispa is a widespread and very common species that is not in danger of extinction. It has an extent of occurrence (EOO) of 96 726 km² and is therefore listed as Least Concern. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Eastern Cape, Free State, Northern Cape, Western Cape |
Range | This species is endemic to South Africa, and is found from the Bokkeveld Escarpment and Calvinia to Cederberg, Witteberg, Swartberg and Baviaanskloof Mountains. It is widespread across the Great Karoo, extending as far as the western Free State. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Eastern Little Karoo, Eastern Upper Karoo, Gamka Karoo, Tarkastad Montane Shrubland, Karoo Escarpment Grassland, Uniondale Shale Renosterveld, Nardouw Sandstone Fynbos, Kouga Grassy Sandstone Fynbos, Matjiesfontein Quartzite Fynbos, Willowmore Gwarrieveld, Escarpment Arid Thicket, Eastern Gwarrieveld |
Description | It grows in stony clay or sandy flats and slopes. |
Threats |
| A very small proportion (<5%) of this species' range has been converted to crop fields. Subpopulations across the southern Great Karoo are potentially threatened by extensive habitat loss, should planned large-scale shale gas extraction go ahead. This threat is however likely to affect less than 30% of its distribution range, and therefore it is unlikely to lead to Moraea crispa becoming in danger of extinction. |
