Species Profile
Riccardia multifida is a species of liverwort belonging to the family Aneuraceae.
Delicate Germanderwort faces significant threats from habitat degradation and loss due to pollution, drainage, and disturbance of its specialized wetland environments. Climate change poses additional risks through altered precipitation patterns and temperature regimes that affect the moisture-dependent ecosystems this bryophyte requires. The species' limited distribution and specific habitat requirements make it particularly vulnerable to environmental changes.
Key Facts
