In Australia, a significant economic use of the foliage and green pods of acacias has been as stock fodder, especially during times of drought. Species used for this purpose include: A. aneura (Mulga), A. argyrodendron (Black Gidyea), A. blakei (Blake's Wattle), A. cuspidifolia (Wait-a-while), A. deanei (Green Wattle), A. estrophiolata (Ironwood), A. harpophylla (Brigalow) , A. kempeana (Witchetty Bush), A. omalophylla (Yarran), A. pendula (Weeping Myall), A. pruinocarpa (Black Gidgee), A. saligna (Coojong), A. sparsiflora (Currawong), A. stenophylla (Eumong), A. tenuinervis (Scrub Wattle) and A. victoriae (Gundabluey) (see Everist, 1969; Hall et al., 1972; Weller, 1974; Askew & Mitchell, 1978; Cunningham et al., 1981; Mitchell & Wilcox, 1994; Thomson et al., 1994; Lithgow, 1997). The Acacia aneura group in particular provide important fodder for sheep in the arid-zone rangelands of Australia; the latest revision of this group presented in the current Flora of Australia volumes 11A and 11B, should lead to a better understanding of the biological attributes of this species complex. Overseas, species such as A. saligna have been used extensively in regions such as North Africa and South America as a fodder plant for sheep and goats (El-Lakany, 1987; Houerou, 2000); its potential for use in south-western Australia is currently being re-assessed. As noted by Thomson et al. (1994) however, the value of Australian acacias as fodder plants should not be overstated; in general these species appear to have relatively low nutritive value and/or digestibility, and their prime role is as a drought fodder reserve. The foliage of some species, notably A. georginae (Georgina Gidgee), may be extremely poisonous to stock (Everist, 1981). Poisoning seriously affects sheep and cattle production in areas where natural stands of this species occurs (Barnes, 1958). Digestibility and nutrient analyses of 29 acacias are given in Vercoe (1989).
