The series’ substantive intellectual objectives were met by careful design of the seminar content, both individually and as a whole. The objective of holding an interdisciplinary conversation around biosecurity was met both by having an interdisciplinary (social science/natural science) team of investigators, and making sure that this carried through into the recruitment of participants. We sought to include members of the policy-making community in the seminars, and this was achieved by publicizing in government departments and agencies. Indeed, effective publicising of the sminar series was essential. Initially we worked through professional association and personal networks (Political Studies Association, Green Politics newsletter, Critical Geographies networks). As the series gathered momentum we added to this by using our website as a point of encounter, and by asking successive seminar participant groups to use their own networks to publicise the series in the manner of a ‘telephone tree’. We also advertised the series around relevant government ministries and agencies such as DEFRA and the Natural England Science Advisory Committee (NESAC), and through the British Ecological Society (BES) Agricultural Ecology Specialist Group, which was an excellent forum to contact land managers, policy practitioners and academics. The Institute of Ecology and Environmental Management included a link to our seminar series advert on their website. We presented a poster on the series and gave out flyers at the Institute of Ecology and Environmental Management (IEEM) conference on ‘Invasive Species: New Natives in a Changing Climate?’ on 23 March 2011 at Hamilton House, London. A copy of this poster has been uploaded onto our website.
