New pasture plants intensify invasive species risk

Published today in PNAS, we highlight the risk of invasion posed by the development and introduction of new pasture taxa (species, subspecies, varieties , cultivars and plant-endophyte combinations).  New pasture taxa are bred with characteristics typical of invasive species and environmental weeds. By introducing novel genetic and endophyte variation, pasture taxa are imbued with additional capacity for invasion and environmental impact.
