Justification | Aloiampelos juddii is a highly localized species. Its range size is very uncertain due to a lack of field data, but its extent of occurrence (EOO) is suspected to be less than 5000 km², and possibly as small as 150 km². It is currently known from one location, but likely to occur at a few more, and is threatened by competition from unmanaged alien invasive plants. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | This species is endemic to the coastal mountains between Gansbaai and Baardskeerdersbos in the Western Cape, South Africa. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Overberg Sandstone Fynbos |
Description | It occurs on southeast-facing rocky slopes in sandstone fynbos. |
Threats |
Large parts of the coastal mountains east of Gansbaai are invaded by dense, unmanaged stands of alien invasive plants, outcompeting native species and causing an ongoing decline in habitat quality. |
Population |
This species is locally abundant (Van Jaarsveld 2008). It is known at only from the type locality, but is likely to be more widespread in similar habitat in the mountains between Gansbaai and Baardskeerdersbos. Field surveys are needed to gain a better understanding of the size and structure of the population. A continuing decline is inferred from an ongoing threat from alien invasive plants.
