Lachenalia nardousbergensis has a restricted distribution range, with an extent of occurrence (EOO) of 4294 km². It is declining across most of its range due to ongoing habitat loss to rooibos tea cultivation, but sill persists at more than 10 locations. It therefore nearly meets the criteria thresholds for Vulnerable under criterion B.
South African endemic
Provincial distribution
Northern Cape, Western Cape
This species has a narrow distribution in the Northern and Western Cape Provinces, where it occurs from the Bokkeveld Escarpment around Nieuwoudtville southwards to the Nardous Mountains and northern Cederberg. One isolated subpopulation has been recorded from the northern tip of the Piketberg.
Habitat and Ecology
Major system
Major habitats
Agter-Sederberg Shrubland, Piketberg Sandstone Fynbos, Cederberg Sandstone Fynbos, Bokkeveld Sandstone Fynbos
It occurs in deep sandy soils on flats and plateaus in mountain fynbos.
It is threatened by ongoing habitat loss to rooibos tea cultivation around Nieuwoudtville, on the Nardous Plateau, Gifberg and in places outside protected areas in the Cederberg.

This species is locally common, and recent field observations indicate that it is still common in the Cederberg, where its habitat is protected. Elsewhere in its range it is declining due to ongoing habitat loss.
