Messing About with the River

Introduction:

This thread 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 thread 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.

The articles in this thread address the following questions:

  • Where does the River Sid rise, and what is its approximate length?
  • What geological features characterise the Sid Valley, and how do they influence the river?
  • How has human intervention, specifically straightening and armouring, affected the River Sid's natural processes?
  • What is a "flashy" catchment, and what are some of its consequences for the River Sid?
  • What is the primary purpose of the School Weir, and what is its significant detrimental effect on the river's ecology?
  • Describe the historical changes to the River Sid's outlet at the coast and the role of the shingle ridge.
  • Why are river flies considered indicators of river health?
  • What are two main sources of pollution affecting the water quality of the River Sid?
  • Name two invasive non-native plant species that are a significant concern along the River Sid and explain why.
  • What impact do dogs have on the River Sid environment, particularly in The Byes?
