Hatcher's Pawwort
Barbilophozia hatcheri
Hatcher's Pawwort is a small, leafy liverwort characterized by its distinctive three-lobed leaves and reddish-brown coloration when mature. This bryophyte forms low, creeping mats on acidic substrates and plays an important ecological role in soil stabilization and moisture retention in specialized microhabitats.

Species Profile
Hatcher's Pawwort is a small, leafy liverwort characterized by its distinctive three-lobed leaves and reddish-brown coloration when mature. This bryophyte forms low, creeping mats on acidic substrates and plays an important ecological role in soil stabilization and moisture retention in specialized microhabitats.
Hatcher's Pawwort faces severe threats from habitat degradation due to climate change, particularly warming temperatures and altered precipitation patterns affecting its specialized montane bryophyte communities. The species' extremely limited range and small population size make it highly vulnerable to stochastic events and ongoing environmental changes in its restricted alpine habitat.
Key Facts
Habitat & Distribution
Hatcher's Pawwort grows exclusively on acidic, nutrient-poor soils and decaying organic matter in montane and subalpine environments. It typically colonizes exposed mineral soil along stream banks, cliff faces, and disturbed areas where competition from vascular plants is minimal.
Threats
