Funck's Rustwort

Marsupella funckii

UnknownLCEULCEU

Overview

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

Funck's Rustwort faces severe pressure from atmospheric pollution, particularly acid rain and nitrogen deposition, which alter the chemistry of its specialized montane habitats. Climate change poses an additional threat by shifting temperature and precipitation patterns in high-altitude environments where this bryophyte has evolved to thrive. The species' extremely limited distribution and small population sizes make it highly vulnerable to local extinctions from habitat degradation.

Threat summary

Habitat

Funck's Rustwort inhabits acidic, nutrient-poor substrates in montane and subalpine regions, typically growing on wet rocks, cliff faces, and stream banks at elevations between 300-2000 meters. The species requires consistently moist conditions and is particularly associated with areas of seepage or spray from waterfalls and streams in mountainous terrain.
