Australia planted eucalyptus trees to fight rising soil salinity; decades later scientists found the plantations were changing groundwater but not the soil nature

• Image Credit: ERA NurseriesAustralia planted eucalyptus trees to fight rising soil salinity, hoping that thirsty, deep-rooted vegetation could help control the groundwater processes behind the problem.
• A long-running experiment in south-western Australia later showed that the effects of such plantations were more complicated than simply planting trees and waiting for the land to recover.
