Habitat & Geographic Range

Cider Gum

Habitat

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

Range

Found across Europe (9 countries) and South America (Brazil).

Coastal wattle

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 8 distinct biome types spanning the Afrotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (13 countries), Asia (Israel), Europe (4 countries), and North America (United States).

Cider Gum

The cider gum (Eucalyptus gunnii) is a medium to large eucalyptus tree native to the highlands of Tasmania, Australia, where it grows at elevations up to 1,400 meters in subalpine and montane environments. It is one of the most cold-hardy eucalypts, tolerating severe frosts and occasional snow, which has made it widely popular in cultivation far beyond its native range, particularly in Britain, Ireland, France, and other temperate parts of Europe. In Tasmania, cider gum typically grows along the margins of highland lakes and in subalpine moorland and wet sclerophyll communities. The species reaches 15–35 meters in height, with smooth, pale gray-green to white bark that peels in ribbons. Young foliage is distinctive round and silver-blue, aging to more elongated sickle-shaped adult leaves. The name cider gum derives from the practice of Tasmanian Aboriginal people fermenting the sweet sap that pools in natural wounds to produce a mildly fermented drink. The species is classified as Not Evaluated by the IUCN. Eucalyptus gunnii provides habitat for several Tasmanian endemic species and is considered an important component of highland vegetation communities. In its introduced European range, it is a popular ornamental and windbreak tree. Concerns exist about its naturalization in some European countries where it has established self-sustaining populations.

Coastal wattle

Coastal wattle (Acacia cyclops) is a dense, fast-growing shrub in the family Fabaceae, native to the southwestern and southern coastal regions of Western Australia, from Shark Bay south to the Nullarbor Plain. It grows on coastal dunes, sandy scrubland, and limestone substrates near the sea, where it tolerates salt spray, wind, and summer drought. Coastal wattle produces distinctive circular seeds with bright red arillate coatings, making them highly attractive to birds. Although valued in its native range for coastal stabilisation and revegetation, the species has become highly invasive in southern Africa, particularly South Africa, where it was introduced for dune stabilisation in the 19th century and has since spread extensively across the Cape Floristic Region, displacing native fynbos vegetation. It is listed among the 100 worst invasive species globally by the IUCN Invasive Species Specialist Group. In Australia, it is assessed as Least Concern. Management of invasive populations in South Africa involves mechanical removal and biological control efforts aimed at protecting the critically threatened fynbos biome.
