Habitat & Geographic Range

Buckelwal

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 (5 countries), and South America (Colombia, Ecuador, Venezuela). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Cliff Mallee Ash

Habitat

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

Buckelwal

Among the most acrobatic of the great whales, humpback whales are renowned for their complex, haunting songs sung by males during breeding season — some lasting hours and evolving over time. Reaching 16 meters and 30 tonnes, they undertake the longest migrations of any mammal. Found in all oceans, humpbacks feed on krill and small fish using cooperative bubble-net feeding. Populations have largely recovered from historic whaling.

Cliff Mallee Ash

The Cliff Mallee Ash, Eucalyptus cunninghamii, is a small, multi-stemmed mallee eucalyptus in the family Myrtaceae with a very restricted distribution on cliff faces and rocky gorges in the Blue Mountains and Hawkesbury regions of New South Wales, Australia. Growing in the characteristic mallee growth form, it sprouts multiple slender stems from a large, woody underground lignotuber that enables rapid resprouting after fire. The species occupies sandstone cliff ledges, rock overhangs, and steep gorge walls in heath and scrub communities, often in association with other endemic sandstone species. The white to cream flowers attract native bees and nectar-feeding birds. Eucalyptus cunninghamii is restricted to a narrow geographic range within the Sydney Basin bioregion and is listed as Endangered under Australian national law. Its cliff-face habitat, while partially protected within national parks, faces threats from altered fire regimes, encroachment by invasive plants, and activities that damage the delicate clifftop and gorge vegetation. The inaccessibility of many cliff populations provides some natural protection from direct human disturbance, but limits the feasibility of active management interventions.
