Haplomitrium hookeri

UnknownLCEULCEU

Overview

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

Hooker's Flapwort faces severe pressure from habitat degradation in its specialized wetland environments, particularly through drainage and agricultural conversion of bog and fen systems. Climate change poses an additional threat by altering the hydrological conditions essential for this moisture-dependent bryophyte. The species' extremely limited distribution and small population sizes make it highly vulnerable to local extinctions from even minor habitat disturbances.
