This topic attempts a comprehensive overview of the River Sid in East Devon, detailing its physical characteristics and historical alterations, such as straightening and weir construction. It examines the various threats the river faces, including pollution from agricultural and urban runoff, physical modifications impacting aquatic life, and the significant problem of invasive species like Himalayan balsam and signal crayfish. It also highlights the river's ecology and the wildlife it supports, such as kingfishers, otters, and various insects, while acknowledging the fragility of its ecosystem. Finally, the topic outlines current and proposed management plans aimed at improving water quality, restoring habitats, and addressing flooding and invasive species, emphasising collaborative efforts among community groups and environmental agencies.
