Habitat & Geographic Range

Blauwal

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.

Common Spike-thorn

Habitat

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

Blauwal

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.

Common Spike-thorn

<em>Gymnosporia buxifolia</em>, commonly known as the common spike-thorn, is a spiny shrub or small tree in the family Celastraceae, native to sub-Saharan Africa. This species typically inhabits a variety of vegetation types including bushveld, riverine thickets, rocky hillsides, forest margins, and disturbed areas, demonstrating considerable ecological versatility. It is widely distributed across eastern and southern Africa, with populations recorded in countries including South Africa, Zimbabwe, Mozambique, Tanzania, and Kenya, among others in the region. Classified as Least Concern on the IUCN Red List, <em>Gymnosporia buxifolia</em> is considered stable throughout much of its range. The plant is characterised by its stout axillary thorns, small dark green leaves, and small white to cream flowers followed by three-lobed capsular fruits. It plays an ecological role as a host plant for various insects and as a food source for browsing mammals. Biological traits such as average lifespan, body dimensions, and dietary specifics remain poorly documented in the scientific literature for this plant species. The species is also used in traditional medicine across parts of its range, and its dense thorny growth makes it useful as a natural hedge or barrier plant in agricultural and homestead settings.
