Project summary

Edit project overview to modify the project summary.

DTRIP is a partnership project that will use CRF funds to manage restoration work and to deliver habitat improvements in the Dart and Teign catchment. The partnership, led by the Westcountry Rivers Trust, has been working together for many years, carrying out river restoration and addressing the causes of Wa-ter Framework Directive issues.Through restoration work, the project will address issues including: sediment, which has a direct adverse effect on water quality; diffuse pollution from agriculture and roads, which can impact on river ecology and causes WFD failures; barriers to fish migration, preventing fish from reaching habitat where modeling shows they should be present; interrupted conveyance of river gravels, resulting in reduced spawning habitats for salmonids; habitat loss of wetted and wooded land that has an important role to play in improving water quality & quantity; acidified moorland that creates low pH levels that are detrimental to ecological health of the rivers.
