02Description

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.
