Project summary
TRIP is a partnership project that will use CRF funds to manage restoration work to deliver habitat improvements in the Taw catchment. The partnership, led by the Westcountry Rivers Trust, has been carrying out river restoration and addressing the causes of Water Framework Directive issues together for many years.
The outcomes of the project are the following:
Water quality management – More con-sistent supply of better water quality
Improved biodiversity - increased hab-itat biodiversity and renaturalisation
Social - Improved leisure environment for angling and recreation
Economic - Improved fisheries and spawning for commercial stocks
Flood attenuation and management - Increased wetted and wooded areas
Counteract climate change - Carbon sequestration through wetland sinks
Monitoring surveys and results
