Taxonomy
Scientific Name
Tephrosia inandensis H.M.L.Forbes
Higher Classification
Dicotyledons
Family
FABACEAE
National Status
Status and Criteria
Endangered A2c
Assessment Date

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).
