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.
