Habitat & Geographic Range

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).

Common Birch

Habitat

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

Range

Widely distributed across Africa (South Africa), Europe (6 countries), North America (Canada, United States), Oceania and the Pacific (Australia, New Zealand), and South America (Argentina).

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.

Common Birch

The common birch (<em>Betula pendula</em>), also known as the silver birch, is a deciduous tree with a broad distribution spanning Africa, Europe, North America, Oceania, and South America. Countries in its range include South Africa, several European nations, Canada, the United States, Australia, New Zealand, and Argentina. It is classified as Least Concern on the IUCN Red List. <em>Betula pendula</em> typically grows in a wide variety of terrestrial habitats from tropical lowlands to temperate montane forests, demonstrating considerable ecological versatility. The tree is easily recognized by its slender form, pendulous branches, and distinctive white or silvery bark that peels in papery strips. It is often a pioneer species, rapidly colonizing disturbed and open ground. Common birch plays an important ecological role as a habitat and food source for numerous insects, birds, and fungi. Its wood is valued for furniture, flooring, and plywood production. Biological traits of this species remain poorly documented in the scientific literature.
