Overview
Bosknoopjeskorst (Bacidia circumspecta) is a crustose lichen species that forms thin, grayish to pale greenish crusts on bark surfaces. This inconspicuous lichen produces small, dark apothecia (fruiting bodies) and plays an important ecological role as a pioneer species in forest ecosystems, contributing to nutrient cycling and providing microhabitat for invertebrates.
Bacidia circumspecta, a critically endangered lichen species, faces severe threats from habitat loss and degradation of its specialized substrate requirements. Air pollution and climate change are significantly impacting the delicate environmental conditions this lichen needs to survive, while its extremely limited distribution makes it highly vulnerable to local extinctions.
Habitat
Bacidia circumspecta grows exclusively on the smooth bark of deciduous trees, particularly favoring the trunks and larger branches of mature beech, oak, and maple trees in old-growth and semi-natural forests. The species requires stable microclimatic conditions with high humidity and minimal direct sunlight, typically found in the understory of well-established woodland ecosystems.
