Populations are also found in montane and highland environments at higher elevations.

Range

Found in Norway. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Crested Lark

A medium-sized lark named for its distinctive long, pointed crest, crested larks inhabit dry, open country, agricultural land, roadsides, and desert margins across Europe, North Africa, and Asia east to China. They are ground-dwellers rarely perching in trees, walking confidently with the crest raised. Less migratory than most larks, many populations are resident year-round. They produce a rich, melodious song from ground-level and low perches. Populations in Western Europe are declining due to agricultural changes.

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.
