Presence in Australia
Widespread, in most catchments and districts.
This specie has been identified in the following Australian states: Qld, NSW, ACT, Vic, Tas, SA, NT.
Various vegetation communities.
Erect or spreading tree, 5-12m high. Greyish bark and sickle-shaped "leaves".
Distinguished from Blackwood (A. melanoxylon) by its longer, sickle-shaped "leaves", different flowering time and habitat (although they occasionally grow together). Funicle (ovule or seed stalk) is cream and folded under the seed in Lightwood, and red, encircling the seed in Blackwood.
Well-drained soil including shallow dry soil in hill country. Open situations. Resists frosts. Tolerates fire, most droughts, and strong wind (although form may be affected). Resents poorly-drained soil.
Very long-lived. Moderate growth rate. Wasps form galls on flower buds in some areas. Conspicuous woody galls also caused by a fungus.
Pale yellow to almost white, usually Dec-Apr.
Mid-spring to autumn. Seed may take 11 months to form. Monitor regularly, as seeds dropped soon after maturity. Dust from pods and other debris can irritate.
From scarified seed (±28 viable seeds per gram). Pour boiling water over seed and soak for several hours before drying and sowing.
By root suckering, from soil-stored seed after disturbance, such as fire, ripping and ploughing, and from cut stumps. Disturbance reduces competition for moisture and light, and enhances germination. Establishes well when direct seeded.
Shade and shelter
Useful medium-level cover, long-lived plant in windbreaks. Fair shade, resistant to de-barking by livestock, and tolerant of open paddock conditions and stock camps. Fencing remnants recommended to preserve and regenerate trees.
Excellent recharge control on rocky hills. Erosion control through spreading root system. Legume, improves soil fertility through "fixing" nitrogen.
Very good fuel, but often too small.
Hard, close-grained, dark-brown with yellowish lines. Similar quality to Blackwood (A. melanoxylon) timber. Takes a high polish, and is interesting for turning and cabinet work. Bark useful for tanning.
Excellent habitat. Insects, such as ants, and birds, including parrots and native pigeons eat seed. King Parrot eats half-ripe seed pods. Because it flowers when other flowers are scarce, provides valuable pollen for many insects, including wasps which parasitize pasture grubs. Insect-eating birds also attracted. Galls, formed by wasps, provide habitat for other insects. Grubs in bark provide valuable food for birds including the Black-faced Cuckoo-shrike. Excellent roost sites for birds.
Fibre made into string. Leaves used as a fish poison. Bark used medicinally to treat skin diseases. Timber used for woomeras.
Attractive summer-flowering ornamental and shade for gardens and rockeries. Shallow roots do not interfere with utilities or raise footpaths. Suckers if cut back severely or if roots are damaged. Susceptible to snails when young.
Leaves produce yellow dye with alum, and brown dye when copper is used as mordant.
