Wilderness Landscape & Natural Heritage
The River Tweed Special Area of Conservation (SAC) spans approximately 150 kilometers across the Scottish Borders and Northumberland, England, encompassing the river itself and adjacent riparian habitats. It is designated under the European Union's Habitats Directive to protect the natural environment of one of the UK's most ecologically significant rivers. The Tweed is famed for its populations of Atlantic salmon (Salmo salar), freshwater pearl mussels (Margaritifera margaritifera), otters, and a variety of coarse and game fish species. The river environment supports important spawning grounds and diverse aquatic plant life, contributing to its ecological significance. Historically, the Tweed has played a vital role for local communities through fishing and agriculture. Today it remains an important fishery and a destination for anglers pursuing salmon and trout. Recreation on the river includes fishing, kayaking, and riverside walking. The surrounding landscape features rolling hills, historic castles, and traditional Scottish Borders villages, enhancing its cultural appeal. Visitors come to enjoy scenic views, wildlife observation, and the peaceful river environment. Conservation efforts focus on maintaining water quality and protecting the diverse species that rely on the habitat, including native fish populations and rare invertebrates. The River Tweed SAC strikes a balance between recreational use and environmental protection, making it a significant site for both nature lovers and outdoor enthusiasts.
