Mesembryanthemum tomentosum

Declining

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Mesembryanthemum tomentosum faces severe threats from urban development and agricultural expansion across its extremely limited range in the Western Cape of South Africa. The species' specialized habitat requirements make it particularly vulnerable to land conversion, while invasive alien plant species compete for resources in its fragmented coastal and inland populations. Climate change poses an additional threat through altered precipitation patterns that could disrupt the delicate moisture balance this succulent requires.

Threat summary

Habitat

This succulent species inhabits specialized coastal and inland habitats in the Western Cape region of South Africa, typically growing in sandy soils and rocky outcrops. It occurs in Mediterranean-climate vegetation types including fynbos and succulent karoo, where it has adapted to seasonal rainfall patterns and well-drained substrates.
