Overview

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

Spruce's Leskea faces severe threats from habitat degradation and loss of its specialized bryophyte communities in temperate and boreal forest ecosystems. Climate change poses additional risks by altering moisture regimes and temperature conditions essential for this moss species' survival. The species' limited distribution and specific ecological requirements make it particularly vulnerable to environmental changes and human disturbances.
