10. Watervole reintroduction at Sawbridgeworth Marsh
Theme: Habitats and wildlife
- To maintain and enhance the river's natural habitats and wildlife
To address the problems of declining bankside habitat and the remnant invasive mink population, then re-establish watervoles in the Stort valley by reintroducing them to Sawbridgeworth Marsh.
Water voles are absent through the entire Stort catchment due to predation by the invasive American mink, and a decline in suitable bankside habitat. This project aims to set up Sawbridgeworth Marsh as a reintroduction site. In order for this project to be successful, mink must continue to be controlled throughout the catchment, and habitat improvement, in terms of removing over-shading trees and vegetation, must be carried out.
