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 Button medic (Medicago orbicularis). Button medic is a temperate annual pasture legume native to the Mediterranean region, which is adapted to well drained, alkaline sandy loam soils (pHwater > 6.5) in low rainfall (AAR > 275mm) temperate cropping zones. Used as a self-regenerating autumn-to-spring growing annual pasture (Howie et al. 2007). A very minor pasture species if grown at all in south-western Australia. In experimental trials in northern Western Australia the annual legumes and herbs had good feed quality but in general, with low forage yields under irrigation, are unlikely to be economically viable (Moore et al. 2021).
