Assessment Date | 2015/08/14 |
Assessor(s) | D. van der Colff & L. von Staden |
Justification | A range-restricted species (EOO 604 km²), known from fewer than 10 locations and potentially threatened by habitat loss to sporadic agricultural expansion. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Clanwilliam to Pakhuis Pass and the Biedouw Valley. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Cederberg Sandstone Fynbos, Olifants Sandstone Fynbos |
Description | Sandy slopes and flats, often on deep sandy soils, but also sometimes in shallow sandy soils over sandstone rock sheets. |
Threats |
| Potentially threatened by habitat loss to sporadic expansion of crop fields. |
Population |
Moraea maximiliani is often locally abundant, and some records indicate that it is able to persist even in disturbed places. A small proportion (<5%) of its habitat is cultivated, but agricultural expansion is only likely to affect subpopulations on deep sandy soils that can be ploughed - those on sandstone pavements are unlikely to suffer decline. There is some sporadic agricultural expansion north-east of Pakhuis Pass, but this affects only a small proportion of the population. In addition, more than 50% of its habitat is protected in the Cederberg Wilderness Area.
