Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor(s): Loots, S. & Craven, P.
Reviewer(s): Victor, J.E. & Hilton-Taylor, C. (Southern African Plants Red List Authority)
Justification:
Tylecodon aurusbergensis is assessed as Near Threatened. The RAMAS® Red List version 2.0 software package was used to make this assessment. This species is known from two subppopulations on Aurus mountain (extent of occurrence < 200 km² and area of occupancy < 2 km²). There are likely to be more subpopulations to be discovered. Collecting is not thought to be a serious threat at present, although it is considered a potential threat, and the population is assumed to be stable.

Habitat and Ecology [top]

Habitat and Ecology: Occurs on a vertical cliff, in well protected cracks and other protected spots on mountain slopes (summit of the mountain at 1,082 m). Associated with Holothrix filicornis, Aloe erinaceae, Conophytum ernianum and several Crassula species and other succulent vegetation. This area receives considerable fog precipitation and the species was observed to occur in the wettest places.
Systems: Terrestrial

Threats [top]

Major Threat(s): Collecting is at least a potential threat as succulent collectors enter the Sperrgebiet from time to time as succulent societies and reports were received of them collecting plants in the Sperrgebiet without permits.
