The River Ehen is a river in Cumbria, England.
The river's source is at the west end of Ennerdale Water: it runs west through Ennerdale Bridge where it is joined by Croasdale Beck (flowing from Banna Fell). Ennerdale Water itself is fed by the River Liza.
The Ehen continues past Cleator Moor and Cleator, where it is fed by the River Keekle, moving southwards through Egremont and eventually running parallel to the Irish Sea which it eventually joins at Sellafield at the same point as the River Calder.
The river supports the largest freshwater pearl mussel population in England. [1]
The river is a breeding ground for Atlantic salmon. [2] There is widespread poaching along the length of the river. [3]
The river Ehen was designated a Special Area of Conservation in 2005. [4] [5] The section of the coast into which it flows was designated as the Cumbria Coast Marine Conservation Zone in 2013.
The Ehen is home to the Ennerdale black pearl, a rare black pearl formed in freshwater pearl mussels. [6] It is the only river in England to be part of the project "Pearls in Peril", funded by the European Union's LIFE + NATURE Programme. The project aims to conserve the species at 21 sites in the UK. [7] The freshwater pearl mussel relies for part of its life on the presence of salmonids, a group of fish including salmon and trout.
Sellafield has previously used water from the River Ehen for cooling on the site, but ceased this operation in the 1990s. There is a weir on Ennerdale Water, and as at 2016 the valley continues to be an important source of drinking water for customers of United Utilities in West Cumbria. [8] However, there are plans to supply these customers using a new pipeline from Thirlmere because the Environment Agency has confirmed that for environmental reasons it will rescind the abstraction licence for Ennerdale. This means United Utilities must stop using it as a source of water by 2025 at the latest, [9] and therefore will need to find one or more alternative sources of water.

The River Esk is a river in North Yorkshire, England that empties into the North Sea at Whitby after a course of around 28 miles (45 km) through its valley of Eskdale. The river's name is derived from the Brythonic word "isca" meaning "water". The Esk is the only major river in Yorkshire that flows directly into the North Sea; all other watercourses defined as being major rivers by the Environment Agency, either flow to the North Sea via the River Tees or the Humber Estuary.
The River Clun runs mostly through Shropshire, England and joins the River Teme at Leintwardine, Herefordshire. The Clun Valley is part of the Shropshire Hills AONB.

The United Kingdom Biodiversity Action Plan or (UK BAP) was the UK government's response to the Convention on Biological Diversity, opened for signature at the Rio Earth Summit in 1992. The UK was the first country to produce a national Biodiversity Action Plan. It was published in 1994 and created action plans for priority species and habitats in the UK that were most under threat so as to support their recovery.

The Rede is a river in Northumberland, England. The river rises on Carter Fell on the Anglo-Scottish border feeding Catcleugh Reservoir and joins the River North Tyne below the village of Redesmouth. The Rede is one of only two rivers in the North East of England that has the freshwater pearl mussel in its waters.
Unionida is a monophyletic order of freshwater mussels, aquatic bivalve molluscs. The order includes most of the larger freshwater mussels, including the freshwater pearl mussels. The most common families are the Unionidae and the Margaritiferidae. All have in common a larval stage that is temporarily parasitic on fish, nacreous shells, high in organic matter, that may crack upon drying out, and siphons too short to permit the animal to live deeply buried in sediment.
