When I first came to Herefordshire 16 years ago as a Conservation Officer for English Nature – now known as Natural England – I was closely involved in the the decision to declare the River Lugg a Site of Special Scientific Interest (SSSI) because of its outstanding importance for wildlife. My small team spent hours walking the whole length of the river and contacting all the owners to make sure they were all aware of the special nature of the Lugg. We explained why it was important for wildlife and a list of activities that were likely to damage it – for which they would have to have consent before carrying out.
Little did I suspect that over a quarter of a century later that as Chief Executive of the Herefordshire Wildlife Trust, I would be called upon to defend the very river which I thought I had protected all those years ago.
What happened to the River Lugg?
At 8.06pm on Tuesday 1st December, one of our members alerted us to the fact that an area of the River Lugg appeared to have been bulldozed and reprofiled, with all trees grubbed out and vegetation scraped away down to bare earth. By 11.20pm another source had confirmed that a major incident had occurred.
First thing the following morning one of our reserves officers walked the public pathway to view and photograph the work and report back – to ensure that the reports were correct. Sadly, it was even worse than we had feared. The River Lugg SSSI had been bulldozed over a stretch about a mile long; we all felt absolutely devastated.
What impact will this have?
The initial informant reported that a 16-tonne excavator had been working in the river and it is clear that this has been used to widen the channel, drag up the gravel spawning beds onto land, reprofile the bank and spread spoil over a considerable area of land behind the bank.
All the trees and vegetation immediately upstream of the bridge have disappeared and the riverbank lies straight and bare, with every vestige of wildlife destroyed.
This was formerly one of the most attractive stretches of the river. It was the haunt of otters and kingfishers and the riverbed gravels would have been key spawning grounds for salmon and trout, which should be spawning right now. The eggs settle down into the gaps between the stones where they are protected from predation and are oxygenated by water flowing through the stones.
In addition to the direct destruction the work has mobilised tonnes of soil into the water. This will have drifted downstream, settling into the riverbed over a considerable distance. This silt clogs up the river gravels, smothering the fish eggs and depriving them of oxygen. It also damages the gills of freshwater invertebrates and smothers plants, as well as carrying agricultural pollutants such as phosphate into the water.
With no vegetation to stabilise the backs until next spring, every time the river floods this winter soil will pollute the water.
How could this happen?
Work of this scale requires a range of formal consents:
- A felling licence from the Forestry Commission
- Formal consent under Wildlife and Countryside Act from Natural England
- Flood defence consent for engineering works from the Environment Agency
To obtain these consents, a landowner has to submit sufficient ecological information to identify, avoid and mitigate any impacts on the Special Area of Conservation further downstream, to the competent authority to enable them to carry out a Habitats Regulations Assessment.
In cases where environmental legislation appears to have been breached, the relevant Statutory Authorities must investigate the incident and where there is sufficient evidence of a breach, they should consider the option of prosecution.
On Friday, staff from Natural England, The Environment Agency, The Forestry Commission and Herefordshire Council were observed arriving on site with West Mercia Police, to gather evidence of the work done and its impacts.
Various conflicting reports around consent being gathered has surfaced, and we will be watching the outcome of the investigation with interest.
Why did this happen?
It has been reported in the media that the individual who undertook this work did so to protect nearby houses from floods – the same houses that were devastated by Storm Dennis floods last year.
Poor flood management
Flooding is a truly terrible reality, which can devastate lives. However, the bulldozing of the River Lugg is unlikely to resolve local flooding problems. Although this river is one of the most natural in the country, it is suffering from a range of harmful activities many of which have accelerated since the river was given the protection of SSSI status. Since the 1990s, huge expanses of floodplain meadow alongside it have been ploughed up, initially for potatoes and now increasingly for crops such as maize.
In former days, rough uncultivated grassland, with fringes of trees, acted as a sponge to absorb rainwater into the soil and slow the flow of water across the floodplain. However, the most recent intensively farmed potato and maize fields become compacted by farm machinery and the soil is left bare and exposed for large parts of the year.
Rain flows over the surface of the bare soil, washing it into the rivers and taking with it agricultural chemicals, including the phosphate fertilisers which are so damaging to river wildlife.
Meanwhile, the upland parts of the river are still subject to over-grazing by sheep with the added new threat of free-range chickens denuding large areas of vegetation. Once again, these are speeding the flow of water into the river, this time adding chicken faeces to the mix.
This is all happening at a time when climate change, brought about by rising CO2 emissions, is starting to change weather patterns, including increasing the frequently and size of storms. All these factors are combining to increase the number of flash flood events on the river.
Time to slow the flow
We need to accept that our rivers need to be naturally functioning systems and use natural flood management measures to slow the flow of water reaching rivers. Dredging is often cited as a key solution to flooding, but widening, deepening or straightening river channels with the aim of conveying water downstream more quickly can sometimes have little positive effect, and is far from risk free, as this blog by the Chartered Institute of Water & Environmental Management sets out. In rural areas there may be scope to allow water to flow out into the floodplain, which creates extra capacity to hold water in soggy grassland or riverside woodlands which prevents it rushing to built-up areas downstream.
What next for the Lugg?
The most urgent problem is the fact that the river banks are now just bare soil, which will wash into the river in the next flood. Some vegetation will re-establish over the summer, but it will be decades before trees, with their network of stabilising roots re-grow to bind the bank.
We expect the statutory agencies, including Natural England and the Environment Agency to require reinstatement of this river, in addition to investigating the case for prosecution. This will be a clear test of Government’s commitment, as the UK leaves the EU, to achieve its aspiration of being a ‘world leader in environmental protection.’
However, since I left Natural England, this statutory agency has seen its budget slashed from £265m in 2008 to only £85.6m in 2019/20. In Herefordshire we noticed the effect this has had on the ground as the number of staff looking after our beautiful county and fragile wildlife have continued to diminish. I know from personal experience that most of Herefordshire’s grassland SSSIs require annual monitoring visits. The maximum recommended monitoring cycle is 6 years. However, many of the sites in the county, including this stretch of River Lugg have not been assessed since 2010. This is unacceptable.
Meanwhile, cuts to the Environment Agency budget have also reduced the feet on the ground and made enforcement of infringements difficult to pursue, at the time when the threats to the river are massively increasing. Figures released by the Environment Agency in September 2020 figures showed that a magnificent 0% of river, lakes and streams in England are in good health.
These cuts need to be reversed to resource our environmental agencies to the level needed in our modern world. We need the Government to pass a strong Environment Bill which will transfer and strengthen environmental legislation as we leave the EU. The bill will establish a new Office of Environmental Protection, which must be strong, well-resourced and, most important of all, an independent entity with teeth.
Prime Minister, Boris Johnson, recently pledged to have 30% of the country managed for wildlife by 2030. The Wildlife Trusts have been promoting this through our 30by30 campaign which seeks to get nature back into recovery.
