Eurasian beaver

Eurasian beaver (Castor fiber) is classified as Vulnerable (VU) on the IUCN Red List. Facing a high risk of endangerment in the wild, with declining populations and increasing habitat pressure.

Micarea lignaria is a small crustose lichen with granular thallus and tiny grey-green apothecia, adapted to wood and bark substrates. It grows on bare acidic bark, wood, and sometimes peat in temperate and boreal forest environments. This photosynthetic lichen obtains energy through its algal partner and contributes to wood surface colonization.
