Habitat & Geographic Range

blue whale

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 11 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Taiwan), Europe (4 countries), and South America (Colombia, Ecuador). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Coastal White Ash

Habitat

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

blue whale

The largest animal ever known to have lived on Earth, blue whales can reach 33 meters and 200 tonnes — their hearts alone weigh as much as a small car. Found in all oceans, they migrate between polar feeding grounds and tropical breeding areas. Filter feeders consuming up to 4 tonnes of krill daily. Endangered, with global populations estimated at 10,000–25,000 after near-extinction from 20th-century whaling.

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.
