Environmental Standard Operating Procedure 10 Reed Rond Creation after Floodbank Set-back Aim Where setback of river banks is taking place, there is a valuable opportunity to economically dispose of dredged material whilst also supporting conservation gain through assisting in the creation of rond habitat. Engineering solutions to producing quality reed rond, inline with BAP targets. Standard BESL to create raised berm to prevent standing water being retained against toe of flood wall during deposition of dredged material BESL to install lateral compartments to sub divide the area into a series of cells that can be filled Survey for protected species and breeding birds Deposit to no higher than adjacent ronds, as if too dry nettles and willow become established Once material has dried, BESL to cut Environmental Risk dykes and grips into the rond area in Impact Likelihood Mitigation Damage/destruction Medium Survey and of water vole and/or mitigate reptile habitat, (refer to including death of ESOPs 11 and individuals 12) Damage and Low Survey and destruction of mitigate habitat used by (refer to ESOP breeding birds 14) Reed will not Medium establish order to allow the irrigation and circulation of water – thus avoiding stagnant conditions and preventing drying out from occurring.
