Acacia victoriae Benth.

Life form: Evergreen shrub or tree
En: Elegant wattle, Bramble wattle, Narran. Fr: Acacia victoria
Provenance: Australia

Distribution in Israel
The elegant wattle is one of the most frequent alien species in the natural areas north to Beer-Sheva, i.e. in the semiarid region of Israel. Unlike the other Australian acacias found in this region, Acacia victoriae' distribution is not restricted to river banks. A multitude of nascent foci, which may turn to dense stands, have been reported for the first time in 2005. Numerous emerging populations are developing near to afforested patches where Acacia victoriae has been planted.

Proliferation status
According to terminology suggested by Richardson et al. (2000) Acacia victoriae is an "invasive" alien in the region considered.

Acacia victoriae in Israel
The introduction date of Acacia victoriae to Israel is not clear, however it is thought to have been introduced to Israel before the 1970s, and possibly even during the British mandate period. Acacia victoriae was used for soil stabilisation mainly in the semiarid and arid parts of the country.
The elegant wattle was one of the main species planted in the late 1980s as part of the "savanisation" plan on loess soils in the open areas north to the city of Beer-Sheva. It is quite likely that the recent proliferation of Acacia victoriae originates in this afforestation effort.
Numerous foci with Acacia victoriae were recently found, among them pure stands are progressively forming and not necessarily around watering points. Moreover, numerous seedlings were reported in the most developed stands, suggesting a high recruitment level.
The recent proliferation of Acacia victoriae is actually alarming as it seems to have a very high spreading rate. A close follow-up is crucial in order to determine whether this recent proliferation is temporary or is permanent and increasing.

There is virtually no published information about the control methods which can be used against Acacia victoriae.
Since it vigorously regenerates from suckers, physical control is presumably inefficient.
The efficiency of the most common herbicide such as Glyphosate or Triclopyr remains unreported in literature.
No biological methods have been developed so far against the elegant wattle.
