This talk was given as part of Herts & Middlesex Wildlife Trust's 'Science of Chalk Rivers' seminar evening in September 2014. Joe Huddart of Imperial College London discusses his current research on the re-introduction of large woody debris (LWD) on a model river system, the Great Stour in Ashford. He uses a multiple before/after control/impact (MBACI) system to determine the response of a range of ecological variables.
