Project summary

Edit project overview to modify the project summary.


The project has two main objectives (i) to install a comprehensive range of diffuse pollution control and biodiversity enhancement measures in a pilot area covering c.40km2 on the lower Thame which can subsequently be rolled out across the whole catchment. (ii) to complete the preparation of a strategic overview plan for the River Thame catchment, jointly developed by all catchment partners, to maximise the benefits of stakeholder involvement in achieving the aims of the Water Framework Directive. The overview plan will apply the techniques and lessons learned in the pilot area, and elsewhere, to outline a rolling programme of practical works throughout the Thame catchment.
