There are four areas of non-statutory Nature Conservation Sites along the river, Middlebrough plantation just outside Newby Wiske; Stony Lane Pond near the confluence of Stony Lane Beck and Carr Beck; Pepper Arden Bottoms near East Cowton and Pheasantry Wood and Fox Covert near Danby Wiske [REF].
The river passes through farmland bounded by hedgerows with some wet woodland near Kirby Wiske and some grassland near Newby Wiske [REF].
