Working with water companies
Exposure to untreated contaminated wastewater from Combined Sewer Overflows (CSO's) poses a serious risk to people and wildlife; that this can happen within water courses with the highest level of environmental protections highlights the extent of the problem. These sorts of spills have become the normal rather than the exception and this is unacceptable.
We want to see more effective regulation of the water industry to ensure that Combined Sewer Overflows are used legally and within permit conditions and we are extremely concerned about the level of discharges and their impact on our waterways. Our umbrella organisation, The Rivers Trust are campaigning hard on this issue and have created a real time sewage map here.
We will continue to work with our partner organisations to push for increased transparency surrounding discharges, better regulation and accountability on this issue and we support our industry’s calls to ensure that in future they only happen under exceptional circumstances and our beautiful rivers in West Cumbria (and indeed all our rivers) are healthy environments, safe for people and wildlife to enjoy.

Beavers
The European beaver, Castor fiber, was found throughout England (including Cumbria), Wales and Scotland, and is thought to have been hunted to extinction by the mid-16th century. The Department of Environment, Farming and Rural Affairs (Defra) is committed to providing opportunities to reintroduce native species that we have lost from our countryside, including the beaver. Defra states that their reintroduction, when carefully planned and managed, can enrich our natural environment and provide wider benefits for people and other wildlife.
Based on the evidence so far, WCRT believes beavers do have a positive role to play in rivers in Cumbria. However, reintroducing beavers is not without its challenges, such as understanding potential adverse impacts on the lowland / more productive agricultural environments and other iconic species and balancing the opinions of different stakeholders.
The view of WRCT is that every beaver reintroduction proposal needs to be considered on an individual case by case basis. Beavers have already come to Cumbria and there is currently an enclosed beaver trials taking place in the Eden Catchment at Setterah Park on the river Lowther led by Lowther Estate, at CastleTown estate, Rockcliffe, as part of a very ambitious Rewilding scheme and an undisclosed site in South Cumbria.
On WCRT’s patch there is a proposal for beaver releases in the River Ehen and Calder catchments by Forestry England, who have aspired to release beavers into Ennerdale Valley in Cumbria since 2019. Early plans for a partial beaver enclosure were paused in October 2023 because there were concerns about the proposed metal grill across the lower River Liza and its potential to deter salmon and trout from passing to their spawning grounds upstream. A beaver release directly into the wild was not an available option at that time due to DEFRA guidance on enclosed releases only.

River Dredging
Dredging is the process of removing a build-up of sediment from the bed of a watercourse to increase the depth or width of the river channel. Gravel management is the strategic removal of large shoals of gravel that have built up in the river and there is an important distinction. Gravel or silt management can be beneficial in some circumstances but dredging to increase channel capacity (often suggested as a way of reducing flood risk) can cause significant knock-on problems and is not a sustainable method of management as it needs doing repeatedly.
Dredging can:
Make riverbanks unstable and increase erosion rates.
Make water travel more quickly downstream to towns, increasing flood risk
Deposit gravel in areas where it causes problems or increases flood risk
Be detrimental to the ecology, particularly salmon and trout who need gravel to lay eggs into
Sometimes gravel management can help to reduce flood risk. For example, where a bridge or culvert is under capacity, gravels will be deposited and further reduce the capacity of the structure which may cause it to overtop the banks sooner. But in general, dredging will increase flood risk downstream.
Deeper, wider channels allow the channels to hold a greater mass of water and have less storage on the floodplains. This results in a more powerful and faster flow creating larger and earlier flood peaks downstream – it simply moves the problem downstream.
Straightening the natural course of a river (many of our rivers have been artificially modified in this way), shortens the length of the journey the water has to take, so a straighter and shorter river has a higher gradient which means water flows more quickly to towns and villages downstream.
Utilising flood storage areas and Natural Flood Management (NFM) is much more effective and much more beneficial for the natural environment too.
Plastic tree guards
Planting trees is a big part of our work to look after rivers. Trees and woodlands provide many benefits to wildlife, climate change, river health, flood risk and cleaner water for people – to name just a few! Trees also however provide a tasty snack for herbivores. As we have larger populations of herbivores than would have naturally existed, we do need to protect trees as they grow. Fences can be used to keep out livestock, but deer can jump these stock fences and 2-metre high deer fences are expensive to erect and not always appropriate in areas of open access – they also don’t keep out the smaller animals such as voles that nibble at the base of newly planted trees. A common approach therefore is to protect each tree with an individual guard.
Most tree guards are made from polypropylene plastic. As we become more aware of the problems of plastics and micro plastics in the environment, it might seem counter-intuitive to use a lot of plastic tubes as part of environmental enhancement projects. However, polypropylene is biodegradable and breaks down without any toxic effects on the environment. On average, trees need to be in tubes for about five years before they are big enough to withstand browsing pressures. After this time, we remove the tubes and if they are still in good condition we reuse them. We also remove any empty tubes after the first year. Tree care to remove tubes and cut back weeds is just as important as planting trees.
Manufacturers are working hard to produce tree guards made from alternative materials, including recycled cardboard, to date they haven’t been able to withstand the Cumbrian climate but there have been lots of improvements in their design. We will be trialling these for the next couple of years.
Every site has different objectives and constraints that determine what approach we take. For example we don’t always need tubes in areas with lower populations of herbivores or with certain browsing resistant trees such as hawthorn, alder, holly and Scots pine. Additionally some sites require different sized guards depending on the height of the animals eating them. We work closely with the Woodland Trust, landowners and other experts to decide which method of planting and protection is the best. We then keep a close eye on how they grow and which species survive to inform our future planting strategy in the future.
We also share best practice and learning with partner organisations including other Rivers Trusts, the Woodland Trust, Cumbria Woodlands and the National Trust who are also working to find and trial alternatives.

Barrier Removals
West Cumbria Rivers Trust are dedicated to improving the condition of our rivers; unfortunately, this is a mammoth task requiring multiple approaches. One such issue facing rivers is their fragmentation due to the many barriers (weirs, dams, culverts and other man-made structures that interrupt and / or alter the flow of the river) that have been built over the last few hundred years. There are over 23,000 barriers in English rivers (and more than 1 million across Europe), many of which are obsolete, with many more in a decayed state. These barriers pose two main problems: wildlife (especially fish) struggle to get past the barriers, and in many instances are completely barred from accessing the river above or below the barrier; barriers usually stop or alter the natural movement of sediment and gravels that are an essential element of a healthy, naturally functioning river system.
Furthermore, many weirs which are technically passable to migratory fish, still result in injuries to the fish which can result in infections and death, but they also ‘hold up’ fish trying to get past, making them easy prey for birds such as cormorants and goosanders. So whilst any given barrier may look harmless in itself, the vast majority of barriers cause more harm than good.
We recognise some barriers are necessary- especially road crossings and urban infrastructure – therefore fish easements may be the preferred option (structures built into the weir or culvert, that allow better fish passage and gravel movement, including baffles that disrupt the flow, without the need to remove the original obstruction). But in many cases, removal of the barrier makes more sense- particularly the thousands of obsolete, damaged, small structures we sadly see every day. A healthy, free-flowing river is clearly the preferred option.

Mink Management
At West Cumbria Rivers Trust, our mission is to protect and restore the natural health of our rivers and their catchments. Invasive species like the American mink present a serious threat to the wellbeing of native wildlife, including the much-loved water vole and ground-nesting birds. Effective management of invasive species, such as mink, is essential to safeguarding the ecosystems we care for.
Why is the Trust Managing Mink?
Mink were introduced to the UK in the 20th century and have since posed significant risks to native species. Water voles, in particular, have suffered steep declines due to predation by mink, putting this iconic species at risk of local extinction. Our management efforts are aimed at reversing this trend and enhancing the resilience of local ecosystems.
How Do We Approach Mink Management?
We adhere to international principles for ethical wildlife control. We implement lethal control measures with careful planning, in full compliance with legal requirements, and following well-established conservation practices.
Our Management Methods
Before implementing any control measures, we examine all possible methods of control to ensure that lethal control is the only option. Our approach involves:
Humane Trapping: Mink are captured using specially designed traps that provide shelter and are fitted with a remote monitoring device which alerts us when there is an animal inside. This means that we can respond quickly to an alert to ensure the welfare of any animals inside. We will not set traps if weather conditions could compromise animal welfare.
Surveillance and Monitoring: To minimise the capture of non-target species, we bait the traps with mink scent, ensuring we are capturing mink and not accidentally harming other animals. The use of remote monitoring devices means that we can respond quickly and efficiently to a trap when alerted.
Partner Collaboration: We work closely with conservation partners, landowners, and statutory agencies like Natural England to align our efforts with best practices and shared standards.
Legal and Best Practice Standards
Our management of mink is guided by UK laws and regulations regarding invasive species control. The release of mink is illegal, and all activities are carried out in compliance with wildlife legislation. Additionally, we have adopted the ‘7 principles of ethical wildlife control’ to provide assurance that our actions are not only legal but also humane and evidence-based.
Addressing Concerns
We understand the sensitivity around wildlife management, and we take any concerns seriously. If you would like to raise an issue or report an incident regarding our mink management project please get in touch. We will review your concerns thoroughly and take appropriate action in line with our policies.
In Conclusion
Managing invasive species like mink is an essential part of protecting and restoring the ecological balance of our rivers. At West Cumbria Rivers Trust, we remain committed to safeguarding native wildlife and ensuring our actions are both effective and ethical.
