Othonna pygmaea is a rare, range-restricted species with an extent of occurrence (EOO) of 47 km². It is known from two subpopulations, and is not suspected to be in danger of extinction, and may be more common than records suggest. It is therefore listed under the IUCN 3.1 Criteria, globally, as Least Concern but is nationally categorised as Rare.

Habitat and Ecology
Major system
Major habitats
Nardouw Sandstone Fynbos, Bokkeveld Sandstone Fynbos, Cederberg Sandstone Fynbos
It occurs in shallow depressions or crevices in sandstone pavements.
There are no severe threats to Othonna pygmaea. Its specific habitat is not suitable to cultivation, which is the dominant cause of habitat loss for plant species in this region.

It is a rare and localized habitat specialist, known from two subpopulations, and last recorded in 1972. Plants are small and very easily overlooked, and therefore it is likely to be more common than records suggest. Field surveys are needed to gain a better understanding of the distribution and abundance of this species. The population is not suspected to be declining.
