Alice Eley

Wiltshire Wildlife Trust
"We appointed Rivers Ecology to undertake detailed designs and modelling for a river restoration and online wetland creation scheme on a SSSI/SAC designated chalk stream aimed to restore natural processes whilst also capturing phosphorus. The Rivers Ecology team had the unique experience of working on nutrient capturing chalk stream wetlands in the past and were able to use their expertise to design an effective scheme in line with the requirements of the designated status of the river. There was a lot of discussion on the project design with stakeholders and Lily and Jonathan’s expertise were invaluable to help inform and adapt the designs as the project developed. We are delighted with the final design and are looking to secure funding to deliver this pioneering, online, chalk stream, nutrient offsetting wetland"
