Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
Threelobed Bazzania faces severe threats from habitat destruction and degradation of its specialized bryophyte communities in moist forest environments. Climate change poses additional risks through altered precipitation patterns and temperature regimes that affect the delicate moisture balance required for this liverwort's survival. Pollution and atmospheric changes further compromise the sensitive ecosystems where this species occurs.
Key Facts
Habitat & Distribution
Moist temperate and boreal forests, particularly on decaying logs, tree bases, and humid rock surfaces in shaded understory environments. Requires consistently high humidity and occurs primarily in old-growth forest communities with stable microclimate conditions.
Threats
