Description | Hills in Polokwane Plateau Bushveld. |
Threats |
| This species occurs in a small area enclosed by expanding urban and rural settlements, and the area has been transformed by agriculture. However, this species is unlikely to have lost significant proportions of its habitat to agricultural expansion due to its occurrence on rocky hills unsuitable for cultivation, but the habitat is impacted by overgrazing and trampling (R. van Tonder, unpublished data). It is likely to be declining due to ongoing habitat loss to development of rural settlements.
Many of the hills in this area are used for quarries. Quarrying is likely to cause continuing decline of at least one subpopulation, where hill on which it grows has already been largely destroyed (R. van Tonder unpublished data).
In addition, this species is highly sought after in horticultural collections. Plants are selling for around 85 US$ on the internet (A.J. Hankey pers. comm. 2016). Illegal collection of wild plants is a very severe threat to the highly localized population. |
Population |
Scattered groups of 5-40 individuals (Venter & Edwards 1998). Ledebourias tend to occur in patches, and there may be many patches at the localities given above. It is, therefore, very hard to estimate the total population and surveys are needed.
