Scientific Name | Senecio holubii Hutch. & Burtt Davy |
Higher Classification | Dicotyledons |
Family | ASTERACEAE |
National Status |
Status and Criteria | Critically Endangered (Possibly Extinct) |
Assessment Date | 2016/09/27 |
Assessor(s) | L. von Staden & N. Hahn |
Justification | Senecio holubii is a very poorly known species last recorded in 1876. Natural vegetation in the area where it was last seen is severely degraded due to expanding settlements, crop cultivation and overgrazing, and it is possibly extinct. |
Distribution |
Endemism | South African endemic |
Provincial distribution | North West |
Range | Zeerust district. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Dwarsberg-Swartruggens Mountain Bushveld, Zeerust Thornveld |
Description | Unknown. |
Threats |
| The area where this taxon was collected is now densely populated and extensively cultivated. Overgrazing is also a major cause of degradation and loss of plant diversity within this species' range. |
Population |
This species is only known from the type specimen, collected in 1876 in a remote area of South Africa near the border with Botswana. This area is botanically relatively poorly explored, and it may be overlooked. However, a recent field survey of rare, endangered and endemic plants of North West province found the area to be severely degraded, and the species could not be relocated (Hahn 2013). The status and trend of the population is not known, and it is possibly extinct, but more field surveys are needed to confirm this.
