Pseudoleskeella papillosa

Local name: raspdvärgbågmossa

UnknownVUEUVUEU

Overview

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

Pseudoleskeella papillosa faces severe decline due to habitat degradation from air pollution and acid rain, which alter the chemical composition of its substrate rocks and bark. Urban development and quarrying activities destroy the calcareous rock faces and old-growth forest habitats essential for this moss species. Climate change compounds these pressures by altering moisture regimes and temperature patterns that this specialized bryophyte requires for survival.

Threat summary

Habitat

This moss species typically grows on calcareous rocks, limestone cliffs, and the bark of deciduous trees in humid, shaded environments. It favors old-growth forests and undisturbed rocky outcrops where stable moisture conditions and specific pH levels are maintained.
