Justification
A formerly widespread species that has declined extensively, currently occupying a few small isolated fragments of lowland sand fynbos (EOO 645 km², AOO <25 km²). The severely fragmented population continues to decline due to ongoing habitat loss and degradation.

Habitat and Ecology
Major system
Terrestrial
Major habitats
Swartland Shale Renosterveld, Swartland Silcrete Renosterveld, Cape Flats Sand Fynbos, Atlantis Sand Fynbos, Hopefield Sand Fynbos, Swartland Granite Renosterveld
Description
Seasonally damp loamy soils on sandy flats.
Threats
This species has lost more than 80% of its habitat to urban and agricultural expansion. Remaining subpopulations are mainly threatened by competition from dense, unmanaged infestations of alien invasive plants, which affects four out of five remaining subpopulations. Additional threats include ongoing habitat loss to urban and industrial expansion, overgrazing and inappropriate fire management.
Population

Babiana leipoldtii's population has been fragmented by extensive habitat loss. Currently the largest remaining subpopulation occurs scattered across several fragments of lowland sand fynbos between Malmesbury and Mamre. There are three other remaining subpopulations all confined to small, isolated fynbos remnants between Hopefield and Klipheuwel, and all continue to decline due to ongoing habitat degradation.
