Scientific Name | Indigofera quinquefolia E.Mey. |
Higher Classification | Dicotyledons |
Family | FABACEAE |
National Status |
Status and Criteria | Endangered A3c; B1ab(iii,v) |
Assessment Date | 2023/02/09 |
Assessor(s) | B. du Preez & H. Mtshali |
Justification | A population reduction of more than 50% is projected for this range-restricted habitat specialist (extent of occurrence 24 km²), within the next three generations (15 years) if the spreading alien invasive pines are not managed. This species is known from three locations on the southern slopes of the Riviersonderend mountains. A continuing population decline is inferred from the increasing impact of alien invasive plants within its habitat. Therefore, this species is listed as Endangered under criteria A and B. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | This species is endemic to the Western Cape where it occurs on the Riviersonderend Mountains, Galgeberg. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | South Sonderend Sandstone Fynbos |
Description | This bushy shrublet grows up to 20 cm tall in the montane fynbos, at 1600 m. |
Threats |
Recent field observations indicate that alien invasive pines have spread and increased in density on the southern slopes of Riviersonderend Mountains, putting many native local endemic species at risk. There may be other pockets of this species scattered along the high slopes of the Genadendal and Riviersonderend, but these cannot be confirmed, and these areas are also invaded. |
Population |
Apart from the few historical records, this species is known from three subpopulations recorded on iNaturalist. It is rarely recorded as it is found in extremely tough to climb mountains at high altitudes. It is prolific after a fire. Due to spreading pines within its habitat, a population reduction of more than 50% is projected to be met within the next three generations (generation length 15 years). A continuing population decline is inferred from the increasing impact of alien invasive plants in its habitat on the Riviersonderend Mountains.
