Overview

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

Mannia sibirica faces severe threats from habitat destruction due to deforestation, mining activities, and urban development across its limited range. Climate change poses additional risks by altering the specific moisture and temperature conditions required for this bryophyte's survival, while pollution from industrial activities degrades the pristine environments it depends upon.

Threat summary

Habitat

This liverwort species inhabits moist, shaded environments in boreal and temperate forests, typically growing on decaying logs, soil, and rock surfaces in areas with high humidity and stable moisture conditions. It is particularly associated with old-growth forest ecosystems and undisturbed woodland environments across northern regions.
