Lecanographa lyncea is a rare, crustose lichen that grows on the bark of ancient, veteran trees in old-growth woodland. It produces elongated lirellate apothecia and is considered one of the most sensitive indicators of undisturbed, long-continuity forest ecosystems in Europe. Critically Endangered, it faces severe threat from habitat loss, veteran tree decline, and air pollution.

Polar bear

The largest land carnivore on Earth, polar bears can exceed 700 kg and are found across Arctic sea ice from Canada to Russia. Highly specialized marine mammals that rely on sea ice to hunt ringed and bearded seals. Excellent swimmers capable of covering vast distances in open water. Listed as Vulnerable, with populations under severe pressure from rapid Arctic sea ice loss due to climate change.
