In order to lower salinity levels in Australia's Mullay-Darling watershed, a pilot study using water transpiration credits is being tried to increase forest cover. A company, State Forests, is managing 2 million hectares of public native forests along with increasing amounts of planted forests. Local irrigation farmers have entered into an agreement with State Forests to support tree planting in turn for salinity credits. The goal is large scale reforestation, 40% reforestation is the goal to reverse the current salinity problem.
