The South Hams River Improvement Project (SHRImP) |
Project summary
SHRImP is a partnership project that will use Catchment Restoration Funds to manage restoration work to deliver habitat improvements on the South Hams Rivers. The partnership, led by the Westcountry Rivers Trust, has been carrying out river restoration and undertaking works to address the causes of Water Framework Directive issues for many years.
Through restoration work the project will address issues including:sediment which has a direct adverse effect on water quality; barriers to fish migration, preventing fish from reaching their natural spawning grounds; fertiliser run-off into rivers which can cause nutrient enrichment and have a negative impact on river ecology; acidified moorland that creats low pH levels that are detrimental to the river’s ecological health;interrupted conveyance of river gravels, reducing spawning habitats for salmonids.
