The EM38 was found to be an effective tool in determining survival and growth response of three Eucalyptus species to levels of soil salinity. Differences in measured tree survival, stand volume and leaf area index were correlated with soil salinity. Of the three species, E.globulus performed best in terms of survival and volume growth to age 10 years under slight to moderate salinity conditions, While E.camaldulensis performed best under moderate to severe soil salinity. The ranking of these species for salinity tolerance is consistent with pot trials and younger field trials.
