Assessor(s)

Justification
Known from one location, with a severe threat of alien plant invasion. Eighty plants were recorded at two subpopulations in 2005 and 2007.
Distribution
Endemism
South African endemic
Provincial distribution
Western Cape
Range
Caledon Swartberg.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Western Ruens Shale Renosterveld, Overberg Sandstone Fynbos, Greyton Shale Fynbos, Western Coastal Shale Band Vegetation
Description
Lower to middle altitude slopes in stony, sandstone-derived soil.
Threats
The Caledon Swartberg is densely invaded by alien plants, which have caused extensive decline and degradation of the natural vegetation. Very little alien clearing has taken place and private landowners often refuse to do clearing, with the result that cleared areas are quickly reinvaded.
Population

Moraea longiaristata was once common on the Caledon Swartberg. However, only two subpopulations are known to remain, one consisting of between 10 and 50 mature individuals, the other of about 30 plants.


Population trend
Decreasing
Conservation
No remaining plants are protected in any formally protected areas.
