Otholobium holosericeum

Unknown

Overview

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

Otholobium holosericeum faces severe pressure from agricultural expansion and urban development across its limited South African range. The species' specialized habitat requirements make it particularly vulnerable to fragmentation, while invasive alien plant species compete directly with native vegetation communities. Climate change poses an additional threat through altered precipitation patterns affecting the Mediterranean-type ecosystems where this legume occurs.

Threat summary

Habitat

This endemic South African legume inhabits Mediterranean-type shrublands and fynbos vegetation, typically occurring on sandy soils in coastal and near-coastal areas. The species shows preference for well-drained slopes and flats within the winter-rainfall region of the Western Cape Province.
