An extremely localized species (EOO 53 km²), known from four to five locations. The population is small, estimated to number fewer than 400 mature individuals, with the largest subpopulation consisting of around 100 mature individuals, and continues to decline due to ongoing habitat loss and degradation, as well as competition from alien invasive plants.

Wet clay flats.
At least 50% of this species' habitat is already irreversibly modified, with loss predominantly to crop cultivation and dam construction. Habitat loss and degradation continues, around the Brandvlei-Kwaggaskloof dams due to overfilling of the dam (A. le Roux pers. obs.), and elsewhere due to overgrazing and continued agricultural expansion. Competition from alien invasive grasses is threatening plants at at least one known location (C. von Witt pers. obs.).

Sparaxis maculosa has a very limited range, and within this area it is known from only three to four subpopulations. Subpopulations are small, ranging from 10 mature individuals, to around 100 mature individuals. The population size is therefore estimated to be no more than 400 mature individuals.
