This ACIAR review assessed project FST/1993/016 - one of a number of ACIAR-funded projects looking at the interaction between land use, ground water and trees, and aspects of the land, including salinity. The reviewers noted the critical importance of salinity in both Pakistan and Australia. The research determined tree water use and long-term salinity of root zones of a broad range of native Australian tree species. Importantly, it built expertise and international networks.
