Scientific Name | Acmadenia burchellii Dummer |
Higher Classification | Dicotyledons |
Family | RUTACEAE |
National Status |
Status and Criteria | Rare |
Assessment Date | 2023/02/27 |
Assessor(s) | L. von Staden |
Justification | This species is a range-restricted species with an extent of occurrence (EOO) of 390 km². It is not in danger of extinction. It is therefore listed under the IUCN 3.1. criteria as Least Concern but is nationally recognised as Rare. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | This species is endemic to South Africa, and is found in Langeberg and western Outeniqua Mountains between Swellendam and Mossel Bay. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | South Outeniqua Sandstone Fynbos, South Langeberg Sandstone Fynbos |
Description | It occurs in mesic proteoid fynbos. |
Threats |
| There are no known severe threats to this species. Land cover data show no significant change in the extent of its habitat between 1990 and 2014. It is potentially threatened by competition from alien invasive plants at Garcia's Pass. |
Population |
It is currently known from three isolated subpopulations. All three subpopulations occur in accessible sites near mountain passes, and it is very likely that more subpopulations exist in intervening mountainous areas. More field surveys are needed to better understand the abundance of this species, and monitoring is required to determine the impact of alien invasive plants on the population.
