Scientific Name | Amphithalea axillaris Granby |
Higher Classification | Dicotyledons |
Family | FABACEAE |
National Status |
Status and Criteria | Near Threatened D1+2 |
Assessment Date | 2023/11/13 |
Assessor(s) | H. Mtshali, A.L. Schutte-Vlok & D. Raimondo |
Justification | This Western Cape endemic has a restricted distribution range, with an extent of occurrence (EOO) of 2299 km² and an area of occupancy (AOO) of 116 km². The species consistently occurs in small, isolated subpopulations, each with fewer than 10 mature individuals. It is potentially threatened by competition from alien invasive plants. It nearly meets the threshold to be listed as Vulnerable under criteria D and is therefore assessed as Near Threatened. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | This species occurs in Langeberg Mountains and Outeniqua Mountains in the Western Cape Province of South Africa. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | South Outeniqua Sandstone Fynbos, South Langeberg Sandstone Fynbos |
Description | It grows in Montane fynbos, sandy soils, south facing slopes at 360-1200 m. |
Threats |
| The lower slopes of the Langeberg north of Swellendam and Outeniqua north of George have been planted with commercial timber in the past, but it is no longer expanding. Invasive pines, wattles and Hakeas are however spreading from the plantations across the lower slopes. If these are not controlled, they may increase in density over time, eventually outcompeting native species. |
Population |
This species mostly occurs in small, isolated subpopulations. Each known subpopulation has fewer than 10 plants. The total population size is unknown; however, it is not suspected to exceed 2000 mature individuals.
