Overview

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

Riccia weinionis faces severe threats from habitat destruction due to urban development and agricultural expansion in its limited range. The species' extremely restricted distribution makes it particularly vulnerable to localized disturbances, while climate change poses additional risks through altered precipitation patterns that could affect the moist conditions essential for this liverwort's survival.

Threat summary
