Hydrocotyle pygmaea
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Hydrocotyle pygmaea faces severe threats from urban development and agricultural expansion across its extremely limited range in southwestern Western Australia. The species' tiny wetland habitats are particularly vulnerable to drainage, water table changes, and pollution from surrounding land uses. Climate change poses an additional threat through altered rainfall patterns that could dry out the ephemeral pools and seepage areas where this diminutive herb survives.
Habitat
This critically endangered herb inhabits seasonal wetlands, ephemeral pools, and moist sandy soils in the Swan Coastal Plain region of southwestern Western Australia. It typically grows in shallow depressions that hold water during winter months but dry out in summer, often in association with other rare wetland flora.
