Estate on Exmoor thrives a year after river project, but at what cost?

In the United Kingdom, specifically at Holnicote Estate within Exmoor National Park, a significant ecological project has taken place. The multi-million pound Riverlands project was announced in 2018, which aims to modify river systems for better ecological outcomes. One year ago, the National Trust completed a project that involved creating wetlands and waterscapes to manage the flow of the River Aller. This project spanned over three years and covered approximately seven hectares, which is a novel approach in the UK. Researchers from various universities are now monitoring its impacts on the environment. The restoration work included filling in a 0.7 mile section of the River Aller and reconnecting it with the floodplain, which has resulted in a slower stream. This alteration facilitates better water level maintenance during dry periods and creates a carbon storage area that benefits local wildlife and the climate. According to Area Ranger Jack Siviter, the changes observed over the last year reflect a thriving ecosystem characterized by lush vegetation and diverse flora and fauna. The introduction of wetlands has attracted a variety of wildlife species such as water voles and eels, alongside various bird species. The once barren area is said to be now transformed into a vibrant oasis. While the site remains closed to public access for now, the National Trust team expresses interest in conducting future tours to promote awareness about the project and its successes. This project is pivotal not only for Holnicote Estate but also serves as a model for potential similar initiatives at other National Trust locations. Going forward, the success demonstrated here could influence how river habitats are managed on a broader scale throughout the UK, combining flood defense with ecological restoration.
