Abstract
Summary: Invasive plants often have different physiological properties, chemical components and nutrient element dynamics from native vegetation, which can contribute to their invasiveness and change soil properties. Lippia (Phyla canescens (Kunth) Greene; family: Verbenaceae) is a perennial herb of South American origin. In Australia, lippia replaces desired species in native and improved pastures and is causing serious environmental and pastoral problems in theMurray-Darling Basin. However, the effect of lippia invasion on the water, carbon and nutrient dynamics of pasture soil is not known. In this study, we compared the carbon and nitrogen stable isotope ratio, soil moisture, organic carbon, and nutrient elements in the plant-soil system on lippia infested land and adjacent native and improved pasture. Comparisons were made at three sites, at Somerset Dam (SE QLD), near Leyburn (Eastern Darling Downs, QLD) and near Maitland (the Hunter Valley, NSW).
