River Thames Scheme: a review of the ecological surveys baseline monitoring

Baseline monitoring is required to predict, and assess post hoc, the impact of the proposed Thames flood alleviation scheme on a number of lake water bodies adjacent to the Thames between Datchet and Teddington, as well as the relevant reaches of the Thames itself. The aim of this report is to provide independent guidance on the baseline monitoring and data gathering necessary to carry out impact assessments (risks, ecological responses, WFD/HD compliance), support scenario modelling, inform post implementation monitoring and guide potential packages of mitigation measures. A monitoring scheme is already in place, and forms the basis for this review.
