Scientific Name | Thorncroftia thorncroftii (S.Moore) Codd |
Higher Classification | Dicotyledons |
Family | LAMIACEAE |
Synonyms | Plectranthus thorncroftii S.Moore |
National Status |
Status and Criteria | Vulnerable D2 |
Assessment Date | 2006/11/15 |
Assessor(s) | M. Lötter, J.E. Burrows & L. von Staden |
Justification | AOO < 20 km², the habitat of this species has been severely fragmented and degraded by forestry plantations and although not currently declining this species is potentially threatened by alien plants that typically invade fragments between plantations. |
Distribution |
Endemism | Not endemic to South Africa |
Provincial distribution | Mpumalanga |
Range | Barberton to Piggs Peak. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Barberton Montane Grassland |
Description | Barberton montane grassland, quartzitic soils. Restricted to rocky outcrops, which may be because these areas are fire refugia. 1525m. |
Threats |
| The habitat of this species has been severely fragmented and degraded by forestry plantations. Too frequent fires in fire break areas could negatively affect populations not sufficiently protected by rocky outcrops (Edwards 2006). On the other hand, rocky refugia that are safe from fires also provide a safe haven for escaped pine seedlings and other exotic species associated with the disturbance caused by pine plantations, which become established in these areas and quickly transforms the open grassland habitat to dense thickets. |
