River red gum forests are historically and culturally important due to (1999) Field Guide to Eucalypts, South-eastern Compared with most species, there is a considerable bank of knowledge Eucalyptus camaldulensis is generally dominant in the community, in a survey undertaken during 1988-1989 (see O’Malley and Sheldon, Butcher, P.A., Otero, A., McDonald, M.W. The seedlings were grown in lysimeters which subjected to three soil moisture regimes including; 100% (well watered), 70% (medium drought stress) and 40% (high drought stress) of field capacity (FC).
