Habitat & Geographic Range

Coastal White Ash

Habitat

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

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.

Coastal White Ash

Coastal white ash (Bersama swinnyi) is an evergreen tree or shrub in the family Melianthaceae, endemic to the coastal and riverine forests of KwaZulu-Natal and the Eastern Cape in South Africa. It grows along forest margins, riverbanks, and in moist kloofs in coastal and scarp forest, typically in well-watered, sheltered sites. The species bears pinnate leaves with opposite leaflets and produces racemes of small white flowers followed by capsular fruits that split open to reveal seeds with red or orange arils. Like other members of the Bersama genus, it plays a role in forest succession and provides food for birds that consume its arillate seeds. Coastal white ash is assessed as Least Concern by the IUCN, with populations found across a broad band of KwaZulu-Natal coastal forest. However, this habitat type has been significantly reduced in extent due to timber harvesting, agricultural conversion, and coastal development. The species is occasionally cultivated in South African gardens for its ornamental appearance and wildlife value. It forms part of the rich forest flora characteristic of the biologically diverse subtropical coastal forests of the eastern seaboard.

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.
