A comparison of tannin contents of bark samples from 18 uneven-aged natural populations of black wattle in Australia showed Tasmanian and Victorian provenances (46.9% and 46.6%) had more tannin in their bark than South Australian and New South Wales provenances (39.4% and 38.8%) (Guangcheng et al., 1991; Li et al., 1994).
