Abstract
Introducing new plants to an area may have both positive and negative effects on the environment, economy and community. To minimise the negative environmental impact of introducing new agricultural species, DPIRD conducts a risk assessment procedure based on widely accepted scientific standards. This report assesses Greater lotus (Lotus uliginosus). Greater lotus (big trefoil, syn. Lotus pedunculatus) is a temperate perennial legume native to Europe, eastern Russia and northern Africa. It is used as a pasture species in New Zealand, the United States and Uruguay. In addition, there are about 100 000ha sown to greater lotus in coastal districts of New South Wales and Queensland. Greater lotus is typically grown on acid soils that are waterlogged for extended periods. Greater lotus has had no commercial impact in high rainfall south-western Australia (Moore et al. 2021) and requires annual rainfall greater than 650mm and a growing season longer than 7.5 months to persist (Sandral et al. 2006). As a temperate species there is no apparent role for greater lotus in northern Western Australia.
