Scientific Name | Freylinia crispa Van Jaarsv. |
Higher Classification | Dicotyledons |
Family | SCROPHULARIACEAE |
Common Names | Kouga Honey-bells (e) |
National Status |
Status and Criteria | Vulnerable D1+2 |
Assessment Date | 2021/01/20 |
Assessor(s) | E.J. van Jaarsveld, D. Raimondo & I. Ebrahim |
Justification | This species is a range-restricted endemic with an extent of occurrence of 12 km² and an area of occupancy (AOO) of 4 km². It is known from less than three locations, with an estimated population size of 200-300 mature individuals. It is potentially threatened by black wattle invasion and agricultural expansion. It therefore qualifies as Vulnerable under Criterion D. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Eastern Cape |
Range | An endemic restricted to the Kouga Valley near Joubertina in the Eastern Cape Province. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Kouga Grassy Sandstone Fynbos |
Description | Plants grow in well drained, steep, east-facing rocky scree in dry fynbos. It is a long lived resprouter, suspected to have a long generation length. |
Threats |
| There has been an estimated 16% loss of habitat in this vegetation type mainly due to agriculture (cereal crops). The transformation has happened in the flat valley bottoms where crops can be cultivated. This species grows on steep slopes but there is still a potential threat of agricultural expansion in the area. A further potential threat is the increase in alien invasive plant populations spreading into the kloofs where the species occurs. |
Population |
This is a range restricted species known from three locations. All subpopulations are small and confined to dry fynbos on steep rocky slopes and kloofs. The notes from three herbarium specimens indicate that there are no more than 50 mature individuals per subpopulation. Recent field surveys by CREW volunteers noted 20 plants. Subpopulations appear to be stable and no loss of mature individuals has been reported. There is a possibility that additional subpopulations exist as there is sufficient intact vegetation in the surrounding area and more intensive surveys have to be conducted however, the number of mature individuals is likely to low. The subpopulations are stable.
