Justification
Indigofera magnifica is a range-restricted species with an extent of occurrence (EOO) and an area of occupancy (AOO) of 12 km². It is known from three locations, and potentially threatened by climate change-related temperature increases and habitat loss to renewable energy developments.
Distribution
Endemism
South African endemic
Provincial distribution
Western Cape
Range
This species is endemic to the summit plateau of the Toorberg-Koudeveld-Meelberg in the western Sneeuberg in the Eastern Cape.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Karoo Escarpment Grassland
Description
It occurs in dolerite-derived loamy-clays and black turf soils on high-altitude plateaus, 1700-2150m.
Threats
Karoo Escarpment Grassland is currently utilised mainly for livestock grazing, but this does not appear to negatively impact the species - plants do not show evidence of damage from foraging or trampling. As a localized, high-altitude summit species, it is likely to be vulnerable to climate change-related increases in temperature. Due to its very restricted range, it is also potentially vulnerable to disturbance and habitat loss to renewable energy developments, particularly wind farms.
Population

This species is known from five subpopulations, each subpopulation consists of many cushion like prostrate individuals growing together on black turf. The population is not suspected to be declining at present.
