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.

Postia lowei is a soft, white to cream-colored bracket fungus forming annual, shelf-like fruiting bodies on decaying conifer wood. It inhabits boreal and montane coniferous forests, growing on dead fallen logs and stumps. This brown-rot saprotrophic fungus decomposes the cellulose of conifer wood, leaving characteristic brown cubical rot.
