Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
Round-headed Club-rush faces severe threats from wetland habitat destruction and degradation due to agricultural conversion, urban development, and water management practices that alter natural hydrological regimes. Climate change-induced shifts in precipitation patterns and increased frequency of extreme weather events further threaten the specialized wetland ecosystems this species depends upon.
Key Facts
