Scientific Name | Lachenalia bachmannii Baker |
Higher Classification | Monocotyledons |
Family | HYACINTHACEAE |
Synonyms | Lachenalia brevipes Baker |
National Status |
Status and Criteria | Endangered B1ab(ii,iii,v) |
Assessment Date | 2007/10/24 |
Assessor(s) | N.A. Helme & D. Raimondo |
Justification | This species has an extent of occurrence (EOO) of 1044 km², and between four and six severely fragmented remaining subpopulations continue to decline as a result of overgrazing, fertiliser runoff and infilling of wetlands. It is therefore listed as Endangered under criterion B. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | This species occurs from Piketberg to Stellenbosch. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Swartland Shale Renosterveld |
Description | Plants grow in lowland flats, on edges of vernal pools on clays. |
Threats |
Habitat loss as a result of the destruction of wetlands is a severe past and ongoing threat. This species occurs in shallow seasonal pools, a highly specialized and extremely limited habitat, within a highly productive agricultural area. Wetlands are often drained or filled in to extend crop fields. Fertilizer and herbicide runoff often result in the pollution and eutrophication of wetlands, which encourages the growth and spread of alien invasive grasses in wetlands. Most wetlands where this species occurs are entirely surrounded by crop fields, in which repeated disturbance often disrupts natural water flow to wetlands. In the Saron area habitat degradation as a result of livestock grazing is also an ongoing threat. |
