Habitat & Geographic Range

Cleft Bramble

Habitat

Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Range

Distributed across Norway and Sweden.

Polar bear

Habitat

Found across multiple habitat types including temperate broadleaf and mixed forests, temperate coniferous forests, and boreal forests and taiga, among 4 distinct biome types within the Palearctic biogeographic realm. 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.

Cleft Bramble

The Cleft Bramble, Rubus laciniatus, known also as the Cutleaf or Evergreen Blackberry, is a vigorous, thorny shrub in the family Rosaceae native to central and southeastern Europe, from the Balkans through to southwestern Asia. It is widely naturalized in western North America, southern Australia, New Zealand, and other temperate regions where it was introduced as a garden plant or for erosion control. The distinctive deeply divided, laciniate leaves with finely cut leaflets distinguish it from other brambles. Like other Rubus species, it produces edible black fruits relished by birds and mammals, making it an important food plant for wildlife, but its vigorous growth and ability to root from stem tips make it an aggressive colonizer and a serious invasive species in many regions outside its native range. In the Pacific Northwest of the United States, Rubus laciniatus forms dense, impenetrable thickets that displace native vegetation and reduce biodiversity. Control is difficult given its extensive root system and the ability of fragments to regenerate. The species is listed as a noxious weed in several US states and Australian states. In its native European range, Cleft Bramble is not threatened and occurs in woodland edges, hedgerows, and scrubby habitats.

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.
