Altai Birch Mouse

The Altai Birch Mouse (Sicista napaea) is a species in the genus Sicista. It is currently classified as Least Concern on the IUCN Red List. Typically found in diverse terrestrial and aquatic ecosystems.

Pyrenula nitida is a corticolous crustose lichen producing a smooth, glossy olive-green to brown thallus with embedded, flask-shaped perithecia on smooth bark of ancient broadleaf trees in humid Atlantic woodland. It is considered a flagship indicator species for long-continuity, old-growth woodland in western Europe. Endangered, this lichen is severely threatened by the loss of veteran trees and ancient woodland habitats.
