Scientific Name | Ledebouria coriacea S.Venter |
Higher Classification | Monocotyledons |
Family | HYACINTHACEAE |
National Status |
Status and Criteria | Critically Endangered B1ab(i,ii,iii,iv,v)+2ab(i,ii,iii,iv,v) |
Assessment Date | 2016/07/22 |
Assessor(s) | L. von Staden & A.J. Hankey |
Justification | A single, small population numbering fewer than 500 plants continues to decline due to ongoing habitat loss. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Eastern Cape |
Range | Port Elizabeth. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Grass Ridge Bontveld |
Description | Alluvial sand and fine gravel underlain by calcrete. Plants occur in shaded places under Pteronia shrubs. |
Threats |
| The only known population of this species is threatened by ongoing habitat loss to urban expansion, particularly uncontrolled expansion of informal settlements. It is also losing habitat to ongoing industrial development - the population occurs in an area earmarked for large-scale economic development. |
Population |
In 1989, the population consisted of five clumps within a 5 km area. The largest clump had about 158 plants, the smallest only 11 plants (Venter 1993). Since then the habitat has been significantly reduced by urban and industrial development, but there are no recent field data on the status of the population. On a visit to the type locality in 2012, two species of Ledebouria were found at the site, but neither of these could be confirmed to be L. coriacea (A.J. Hankey pers. comm. 2016).
