Nodding thistle is an invasive pastoral thistle established across many pastoral areas of Marlborough. Marlborough District Council is aware that this species poses a risk and is supporting research into any opportunities for biological control as they arise. Existing biological control agents released have proved successful but are subject to natural cycles meaning traditional control techniques are required from time to time to keep abundances in check.
