Strumaria perryae is a highly localized species known from one location where it is potentially threatened by habitat loss to agricultural expansion as well as habitat degradation due to overgrazing.
South African endemic
Provincial distribution
Northern Cape
This species is endemic to the Bokkeveld Escarpment north of Nieuwoudtville.
Habitat and Ecology
Major system
Major habitats
Nieuwoudtville Shale Renosterveld
Clay soils derived from karoo shales under low karroid shrubs.
Shale soils on the Bokkeveld Escarpment have been extensively cultivated - there are several crop fields in the vicinity where this species was last recorded in 1990. There is no longer any extensive, active expansion of cultivation of clay soils, however, opportunistic, sporadic expansion of crop fields remains a potential threat. The site was used for livestock grazing, but at the time, grazing appeared to not have a negative impact on the population. Follow-up field surveys are needed to determine whether grazing has had any impact over the last 25 years.

This species was last recorded in 1990, when it was known from a single, small subpopulation. Field surveys are urgently needed to relocate the population, as well as any additional subpopulations that may exist. At the time, the population appeared to be stable, but follow-up monitoring is required to determine the current population trend.
