A new modelling study and investigation into how annual burning on the Walshaw Moor Estate (WME) may affect high river flows in Hebden Bridge has shown that the most effective way of managing the moors in order to reduce the peak flow at Hebden Bridge is to eliminate burning and encourage conservation and restoration of Sphagnum. Over time, this will allow sphagnum to replace some or much of the cotton and moorland grasses and heather.

Practiced over the whole Hebden Water catchment, this management for sphagnum restoration would reduce the peak flow at Hebden Bridge by between 5%-10%.
