Streaky Feather-moss

Brachythecium glareosum

UnknownLCEULCEU

Overview

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

Streaky Feather-moss faces severe decline due to habitat degradation from agricultural intensification and urban development across its limited European range. Climate change poses an additional threat through altered precipitation patterns and increased drought frequency, which directly impacts the moisture-dependent growth requirements of this bryophyte species. Pollution from agricultural runoff and atmospheric nitrogen deposition further compromises the specialized calcareous substrates this moss requires for survival.

Threat summary

Habitat

Streaky Feather-moss typically grows on calcareous soils, limestone rocks, and chalk substrates in open grasslands, quarries, and disturbed ground. It favors well-drained, base-rich soils in areas with moderate moisture levels and requires specific pH conditions found in alkaline environments.

Frequently asked questions

Why is Streaky Feather-moss classified as Endangered?
Streaky Feather-moss is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Streaky Feather-moss faces severe decline due to habitat degradation from agricultural intensification and urban development across its limited European range. Climate change poses an additional threat through altered precipitation patterns and increased drought frequency, which directly impacts the moisture-dependent growth requirements of this bryophyte species. Pollution from agricultural runoff and atmospheric nitrogen deposition further compromises the specialized calcareous substrates this moss requires for survival.
