In this study, we identified the best tree species for the afforestation of salt-affected land. Although some planting trials have been carried out in the wheat belt of Western Australia, minimal detailed data on the mortality and growth rates of trees under salinity stress have been reported. Such data would facilitate the selection of species with sufficient salinity tolerance and high growth rates. In the present study, a cultivation experiment was conducted to clarify the salinity tolerance and growth rates of three Eucalyptus species widely planted in Western Australia. The experimental results were analyzed in terms of height growth, maximum photosynthetic rate, water use efficiency, and total biomass. The results suggest that the most suitable species for afforestation depends on the site environment because of the different salinity tolerance levels and growth rates of trees.
