Scientific Name | Tephrosia inandensis H.M.L.Forbes |
Higher Classification | Dicotyledons |
Family | FABACEAE |
National Status |
Status and Criteria | Endangered A2c |
Assessment Date | 2007/09/19 |
Assessor(s) | L. von Staden |
Justification | A population reduction of >50% is estimated based on 68% habitat loss to urban expansion, agriculture, overgrazing and too frequent fire over the last 100 years. The suffrutescent habit indicates that it is a long-lived resprouter and generation length is estimated as 30-50 years. |
Distribution |
Endemism | South African endemic |
Provincial distribution | KwaZulu-Natal |
Range | Durban to Eshowe. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | KwaZulu-Natal Sandstone Sourveld, Moist Coast Hinterland Grassland, KwaZulu-Natal Coastal Belt Thornveld, KwaZulu-Natal Coastal Belt Grassland, Maputaland Coastal Belt |
Description | Grassland and forest margins, 600-900 m. |
Threats |
Ngongoni grasslands between Durban and Eshowe are extensively transformed (68% transformed according to 1996 land cover data), mainly due to agriculture. Large areas are also severely degraded due to severe overgrazing and too frequent fires (grasslands are sometimes burnt up to three times a year), which reduce the grasslands to a virtual monoculture of the unpalatable Ngongoni grass, Aristida junciformis (C.R. Scott-Shaw pers. comm.). In the immediate vicinity of the type locality, a lot of grassland has also been lost to urban spread as Durban expanded since J.M. Wood's collection approximately 100 years ago. |
Population |
As this species is a long lived resprouter, excessive transformation of the habitat within the last 100 years is likely to have led to at least 50% decline in the population.
|
Population trend | Decreasing |
Conservation |
This species is protected in the Kranzkloof Nature Reserve, Roosfontein Nature Reserve and Dhlinza Forest Reserve (Eshowe). |
Notes |
This species is reported to hybridise with the closely allied Tephrosia glomeruliflora in the Eshowe area (Schrire 1987). |
