I am just wondering how much research they put into the Euc species they used. The 850 Euc. species +, are as different as chalk and cheese regarding the soil, climate requirements root systems and specific characteristics (wood density, durability, etc.). The 3 species used (E.camaldulensis, E. viminalis and E. dunnii) tend to prefer higher rainfall, and deeper, alluvial soils. Other species that would have been more suitable would have been the Euc. mallees and mallets (and the Acacia's), that is pioneering species that have deeper root systems and inherant adaptations to harsher climates and poorer soil types. After such species have become established, only then can larger tree species be employed with greater success.
It dosn,t surprise me that E.camaldulensis was the most successful of the 3 species, after all, it is the most prolific Euc. within mainland Australia. The only place it dosn,t naturally exist, is east of the Great Dividing Range.
