Modifying urban rivers to increase biodiversity
Urban rivers are typically heavily-engineered and polluted with degraded habitats. They are therefore a priority for biodiversity restoration. Research suggests that relatively simple modifications to river walls may potentially encourage biodiversity by significantly improving habitats for plants and animals. The EU's Water Framework Directive requires good ecological status in surface waters by 2015, and as such it is important to encourage biodiversity in rivers and waterways. One way of achieving this is to alter the structure of a river. Naturalistic landscape features, such as meanders, ...
