			\|Project summary=The River Bulbourne is a chalk stream that has been severely impacted by historic alterations, over-abstraction and its interaction with the Grand Union Canal. The one kilometre section is owned by the Box Moor Trust and is common land open to the public.

			Prior to this project, the River Bulbourne was straight, over-wide and silty. Due to high banks and old dredging bunds, the river was disconnected from its floodplain and had little marginal habitat. Excessive grazing pressure resulted in bank erosion and little riparian vegetation. A large weir prevented fish passage and also caused an impoundment upstream further degrading the habitat.

			The chalk stream characteristics had been almost completely lost. What should have been a beautiful gravelly stream meandering through rich, biodiverse floodplain, was actually a silty homogeneous channel with little habitat to provide home to wildlife.
			\|Monitoring surveys and results=We have undertaken an integrated approach to monitoring and evaluation using complementary surveys incorporating professionals, academics and citizen scientists.

			Electrofishing surveys have been conducted prior to delivery phase and post project. Further surveys will be carried out in future years to track population changes.

			A group of volunteers regularly undertake Riverfly monitoring to help us understand the changes to the health of the river’s invertebrate populations.
			We worked with academics from Queen Mary University of London to apply the new Modular River Survey to assess changes in habitat composition as a result of the restoration work. This was complemented by localised detailed habitat assessments, physical biotope mapping and a river corridor survey undertaken by the Environment Agency. Sediment sampling was carried out and methods employed to minimize the introduction of pollutants present in the bank material into the river. We also used real-time monitoring sondes to demonstrate that the water quality of the river remained acceptable throughout the main phase of works. The results will provide a case study to help better inform similar schemes in future.
