Project summary

Edit project overview to modify the project summary.

Many watercourses within the River Rea Catchment are failing to meet the required standards under the Water Framework Directive (WFD) due to failing fish numbers. The River Rea has long been known as a catchment in serious decline as a result of sedimentation, poor agricultural practices and fish migration barriers. The Severn Rivers Trust walkover surveys of the River Rea, confirmed that suspended sediment load is seen to be impacting on the ecological health of the river and a major cause of fish failure. Impacts such as agricultural run-off from fields and bank erosion caused by farm animals are major contributors to an excessive quantity of sediment entering the river system. Also good riparian habitats are in decline due to over shading and over mature and diseased alders dying and falling into the river causing excessive blockages and bank erosion scars.

Measures

Edit Measures

Structural measures
Bank/bed modifications	Bank improvement
Floodplain / River corridor	Removal of barriers
Planform / Channel pattern
Other
Non-structural measures
Management interventions	Riparian Management to increase the amount of light getting through the canopy, promote natural re-growth of bankside plants and increase levels of bank stability and stabilise the spread of Phytophthora amongst the Alders, reducing bank side collapse (another main source of sediment)
Social measures (incl. engagement)
Other	Community engagement is essential to the long term success of the project as it encourages local ownership and support. It is seen as an integral part of an integrated catchment management approach. We will increase and improve community engagement and establish a sense of ownership and responsibility of their rivers through active groups for future improvements and monitoring.
