The Australian Blackwood (Acacia melanoxylon (Leguminosae)) is an Acacia species native in eastern Australia. Known to some as Tasmanian Blackwood or Black Wattle, this tree grows fast and tall, up to 45 m height. It has a wide ecological tolerance, occurring over an extensive range of soils and climatic conditions, but develops better in colder climates. Control of its invasion of natural vegetation, commercial timber plantations and farmland in several host counties incur considerable costs, but its timber value and nursing of natural forest succession provides a positive contribution.

Replaces native non-tree vegetation, such as grassland and shrubland, and transforms such habitats. It invades the understorey of relatively open pine and eucalypt plantations. Tree stands facilitate the establishment of natural evergreen forest species and the development of regrowth forest. Windfalls obstruct water flow along invaded streams and rivers. Root suckering, it may require root barriers when planted for landscaping in built-up areas.
It has been introduced to many countries for forestry plantings and as an ornamental tree. It now is present in Africa, Asia, Europe, Indian Ocean, the Pacific Ocean, South America and the United States. It is a declared noxious weed species in South Africa. It was also recently listed by the California Invasive Plant Council (Cal-IPC) as an invasive weed that may cause limited impact (Knapp 2003). Its use as a street tree is being phased out in some locales because of the damage it often causes to pavements and underground plumbing.

Hello Ferran,

A very unusual Acacia & its bean looking fruit/seeds. At first I thought it was some kind of huge worm or something.

Very nice details & notes.

TFS & regards

Bonjour Ferran,
Une plante vraiment très spéciale, on dirait presqu'un bijou. Ta notice est aussi intéressante, il semble que cet arbre soit une espèce invasive et qui cause des dommages.
J'ai appris quelque chose .
Beau dimanche
Amicalement
