Family:

Fabaceae

Acacia salicina

Cooba

Other Names: Native Willow, Willow, Broughton, Doolan, Willow Wattle.

Name Origin:

salicina – from Latin salicis, referring to pendulous, willow-like habit.

Regional Subspecies:

Occurrence:

Regional:

Becomes more common west of Olympic Highway.

Australia:

Qld, NSW, Vic, SA.

Habitat:

Dry sclerophyll forest, shrubland and woodland in semi-arid regions. Mostly creek banks, and flat alluvial plains and floodplains.

Habit:

Erect or spreading shrub or tree, 3-10 m high. Brownish, finely fissured bark and deep-green foliage on willow-like drooping branches. Often in dense clumps.

Site Preference:

Heavy clay soils to sands. May withstand some inundation. Full sun. Salt tolerant. Drought resistant. Resents frost when young.

Characteristics:

Long-lived. Wind-firm. ‘Leaves’ contain large amounts of tannin.

Flowering:

Pale yellow to almost white, usually Feb-Jun.

Seed Collection:

Dec-Jan. Good crops every few years.

Propagation:

From seed (± 8 viable seeds per gram).

Regeneration:

Often seeds, and suckers freely from the roots. Highly palatable to stock, hence fencing recommended for regeneration. Encourage suckering by root ripping or disturbance.

VALUES:

Shade & Shelter:

Excellent low to medium-level cover in windbreaks, due to bushiness and suckering.

Land Protection:

Valuable in maintaining riverbank stability and for general erosion control, where its suckering is an advantage. Legume — improves soil fertility through ‘fixing’ nitrogen.

Wildlife:

Excellent habitat. Native birds and insects eat seed appendages.

Fuel:

Good.

Timber:

Close-grained, tough, heavy, dark-brown and attractively marked. Used in furniture joinery and craft, and said to rival Blackwood (Acacia melanoxylon) timber. Takes a high polish. Used for making bullock yokes and cart shafts in pioneering days.

First Nations:

Tannin-rich bark used to poison fish. ‘Leaves’ reputedly burnt and ash smoked to produce a narcotizing effect. Seeds eaten in some areas.

Ornamental:

Useful attractive species for gardens and parks, particularly in dry areas. Responds to water during dry periods.

Other:

Excellent drought fodder for sheep and cattle.
