kystbendellav

Bactrospora homalotropa

Kystbendellav (Bactrospora homalotropa) is a crustose lichen species that forms thin, pale grayish to whitish crusts on bark surfaces. This inconspicuous lichen plays an important ecological role in nutrient cycling and provides microhabitat for small invertebrates in coastal and near-coastal forest ecosystems.

02Description

Species Profile

Kystbendellav (Bactrospora homalotropa) is a crustose lichen species that forms thin, pale grayish to whitish crusts on bark surfaces. This inconspicuous lichen plays an important ecological role in nutrient cycling and provides microhabitat for small invertebrates in coastal and near-coastal forest ecosystems.

Bactrospora homalotropa, a critically endangered lichen species, faces severe population decline primarily due to habitat loss and degradation of its specialized substrate requirements. Air pollution and climate change are additional stressors affecting the delicate environmental conditions this lichen requires for survival.

03Habitat

Habitat & Distribution

Kystbendellav grows exclusively on the bark of deciduous trees in humid coastal forests and sheltered valleys near shorelines. It requires areas with consistent moisture from sea mist and fog, typically found within a few kilometers of the coast where maritime influence creates stable humidity levels.
