Wikipedia Abstract

Acacia longifolia is a species of Acacia native to southeastern Australia, from the extreme southeast of Queensland, eastern New South Wales, eastern and southern Victoria, and southeastern South Australia. Common names for it include long-leaved wattle, acacia trinervis, aroma doble, golden wattle, coast wattle, sallow wattle and Sydney golden wattle. It is not listed as being a threatened species, and is considered invasive in Portugal and South Africa. It is a tree that grows very quickly reaching 7–10 m in five to six years.

Invasive Species

Acacia longifolia is a shrub or small tree that is part of the nitrogen-fixing Acacia family. Native to the South-eastern coast of Australia, it has naturalised in many other places and has become invasive in other parts of Australia (Victoria, New South Wales), in New Zealand, South Africa, Spain, Portugal and Brazil. It was primarily introduced into these areas to stabilise sand dunes and as an ornamental. Acacia longifolia is fast growing, and a large part of its invasiveness has been attributed to long-lived seeds. In new locations it displaces native vegetation and modifies ecosystems and habitats.
