Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
Tortula laureri faces severe threats from habitat degradation and loss due to air pollution, urbanization, and climate change affecting its specialized bryophyte communities. The species' extremely limited distribution and specific microhabitat requirements make it particularly vulnerable to environmental disturbances and human activities that alter substrate chemistry and moisture regimes.
Key Facts
Habitat & Distribution
Rocky outcrops, limestone cliffs, and calcareous substrates in temperate regions, typically growing on exposed mineral-rich surfaces and crevices. The species requires specific pH conditions and moisture regimes found in these specialized microhabitats.
Threats
