5. Catchment walkover of the Ash

Theme: Knowledge


  • Learn more about the current state of the river
  • Identify specific problems facing the catchment

Project description

This walkover will help to identify specific issues or problems facing the river, and pinpoint their location.

Ahern Ecology, an ecological consultancy, will conduct a catchment walkover of the river. They will audit the structures and barriers in the river which will cause a problem for fish passage, pinpoint any point sources of pollution or run-off, record invasive species and make a note of any other problems they encounter.

Their report will help to guide the development of projects to improve the river.
