The Rye Brook flows through Ashtead Common, Ashtead Rye Meadows & Leatherhead where it joins the River Mole. Over the years, urban & agricultural development has had a detrimental effect on the Rye Brook, with the result that it supported little wildlife and periodically flooded local houses. By restoring the natural processes such as erosion, the depositing of minerals and the occasional flooding of wetland habitats, we are securing a healthy long term future for both wildlife & people.
