Abstract The establishment and early growth of 12 species within the genera Eucalyptus, Casuarina, Melaleuca and Tipuana was tested on a saline site in southeast Queensland. Electrical conductivity (EC) in the top 50 cm of soil was measured using an electromagnetic induction method and calibrated against the EC of 1.5 soil:water suspensions. The site was then stratified into five salinity classes: 0.75-1.0, 1.0-1.25, 1.25-1.5, 1,5-1.75 and over 1.75 dS m(-1) Relationships were developed for predicting the survival and height production of 18-month-old trees. These regressions explained 15-88% of the variation in survival and 2-66% of the variation in height production. Tree species were grouped by determining the EC level where height production declined by 25% relative to that at 0.75 dS m(-1). Casuarina glauca, Melaleuca bractesta, Eucalyptus moluccana, Eucalyptus camaldulensis, Eucalyptus tereticornis and Eucalyptus raveretiana were all highly salt tolerant (25% reductions over 1.5 dS m(-1)). Casuarina cunninghamiana, Eucalyptus grandis, Eucalyptus melliodora and Eucalyptus robusta exhibited moderate salt tolerance (25% reductions between 1.0 and 1.5 dS m(-1)). The responses to increased salinity of Tipuana tipu and Eucalyptus intermedia (25% reductions at less than 1.0 dS m(-1)) suggest that these species are not suitable for revegetating similar saline sites.
