Adelaide Parklands, with an area of 720 ha around the Adelaide city, has been irrigated with recycled water from Glenelg Wastewater Treatment Plant. Irrigation with Glenelg recycled water with application rate of 4.5ML/year ha would cause annual accumulation of 9 t/ha salts to the soil. This can cause salinity and toxicity for some parklands’ plants but there is a lack of adequate information specific to tolerance to salinity and toxicity of the vegetation in this landscape area. This paper identified the general physiological impacts of toxic levels of sodium, chloride, boron and salt, on some plants in the parklands and also outlined the management measures.
