klippdropplav
Cliostomum tenerum
Klippdropplav (Cliostomum tenerum) is a crustose lichen species that forms thin, grayish-white to pale yellow crusts on rock surfaces. This inconspicuous lichen plays a crucial role in primary succession and soil formation processes, slowly breaking down mineral substrates through biochemical weathering while providing microhabitat for invertebrates and other microorganisms.

Species Profile
Klippdropplav (Cliostomum tenerum) is a crustose lichen species that forms thin, grayish-white to pale yellow crusts on rock surfaces. This inconspicuous lichen plays a crucial role in primary succession and soil formation processes, slowly breaking down mineral substrates through biochemical weathering while providing microhabitat for invertebrates and other microorganisms.
Cliostomum tenerum, a crustose lichen species, faces severe population declines primarily due to habitat loss and degradation from human activities. Air pollution, particularly nitrogen deposition and sulfur compounds, significantly impacts this pollution-sensitive species. Climate change is altering the specific microhabitat conditions this lichen requires for survival.
Key Facts
Habitat & Distribution
Klippdropplav colonizes exposed siliceous rock faces and boulder surfaces in montane and subalpine environments, particularly favoring north-facing cliff faces and rock outcrops with consistent moisture availability. The species typically occurs on hard, acidic substrates in areas with clean air and minimal direct sunlight exposure.
