Australia's first salinity trading scheme, to limit impacts of industrial saline wastewater discharges, operates in the Hunter Region, NSW. Despite it, a recent audit suggests stream salinity levels will continue to rise over the next century. No assessment tools are available to identify causes of salinity increases in sub-catchments of the Hunter. This severely limits rehabilitation strategies aimed at addressing river salinity. Current rehabilitation focuses on revegetation of recharge and discharge areas, with limited understanding of the primary local drivers for salinity, and without assessment of whether rehabilitation is addressing or exacerbating problems. This project aims to supply that understanding.

澳大利亚第一个盐度交易计划，以限制工业含盐废水排放的影响，在新南威尔士州的亨特地区运作。尽管如此，最近的一项审计表明，溪流盐度水平在下个世纪将继续上升。没有评估工具可用来确定猎人分流域盐度增加的原因。这严重限制了旨在解决河流盐碱化问题的恢复战略。目前的恢复侧重于补给和排泄区的植被重建，对导致盐碱化的主要当地驱动因素了解有限，而且没有评估恢复是在解决还是在加剧问题。这个项目旨在提供这种理解。
