Aristea angustifolia

Declining

Overview

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

Aristea angustifolia faces severe pressure from urban expansion and agricultural conversion throughout its limited range in the Western Cape of South Africa. The species' narrow habitat requirements make it particularly vulnerable to the ongoing transformation of fynbos vegetation for housing developments and commercial farming. Climate change poses an additional threat through altered precipitation patterns that could disrupt the seasonal moisture cycles essential for this geophyte's survival.

Threat summary

Habitat

This endemic South African iris inhabits sandy flats and lower mountain slopes within the fynbos biome of the Western Cape. The species requires well-drained, nutrient-poor soils and depends on the Mediterranean climate's winter rainfall patterns for its growth cycle.
