Ecological roles of weeds In an invited plenary talk, Geoff Squire represented the group's ideas on the roles of weeds at the XIII Colloque International sur la Biologie des Mauvaises Herbes held at Dijon, France 8-10 September 2009. The main points of the talk were: weeds have been with us in northern Europe for more than 5000 years - we haven't got rid of them; so we need to understand them better, spend less trying to remove them and make use of their positive roles in the ecosystem. Arable cropping in Scotland is already some way towards coexisting with weeds: its cereal yields and weed seedbanks are both among the highest in the UK!  (Added 14 September 2009)

Monocultures are used in high-input systems to maximise short term profitability, but over time yield and quality can become unstable. This paper considers how diversity can be reintroduced to cropping systems to confer stability without compromising quality. It combines expertise between three of SCRI's programmes: Pathology (ACN), Genetics (JSS) and Environment (GSB).
