From the IUCN Red List Species Account:

 

Range Description

This species occurs in the Upland Succulent Karoo biome, from Nuwerus, just north of the low-lying Knersvlakte, in the Northern Cape Province of South Africa, north to the Hunsberg in Namibia. It is absent from a narrow strip along the coast.

Habitat and Ecology

It is associated with the distribution of granitic inselbergs in dry shrubland and semi-desert. It probably spends a large proportion of its time aestivating in cracks and under layers of granite. It is only active after suitably large rainfall events. It breeds in any small body of water that can hold water for a sufficiently long period to enable the tadpoles to complete their development, such as pools in rocky streambeds, and eroded "tanks" in the granitic bedrock, which have good water holding abilities.

Population

It appears to occur in fairly large populations, but it is seldom encountered due to the low numbers of days per year that it is active (as a result of the low rainfall), and the poor collecting effort in its range.

Population Trend

unknown

Major Threats

Some populations are probably being impacted by mining for copper and quarrying for granite. Otherwise, it is probably not facing any threats.

Conservation Actions

It occurs in the Richtersveld Contractual National Park and in the Goegap Wildflower Reserve. Its presence in the Namaqualand National Park and Ai-Ais Fish River Canyon Trans-frontier National Park (in Namibia) is unconfirmed but likely.

Red List Status

Least Concern (LC)

Rationale

Listed as Least Concern in view of its relatively wide distribution and presumed large population.
