For every £1 invested in hedgerows, as much as £3.92 is generated for the wider economy, new research from CPRE, the countryside charity, has revealed
CPRE is calling on the government to stop dragging its feet and set a target to increase the hedgerow network by 40 per cent by 2050, which would be a win-win-win for climate, nature and the economy
Hedgerows could become champions of climate action and nature recovery while contributing tens of thousands of jobs to hard-hit communities, new analysis from CPRE, the countryside charity, has revealed. The Climate Change Committee (CCC) recommends that the extent of our hedgerow network should be increased by 40 per cent to support the UK government’s goal to reach net-zero carbon emissions by 2050. If the right hedgerows are planted in the right place, for every £1 invested in hedgerow planting, as much as £3.92 is generated in the wider economy. Crispin Truman, chief executive of CPRE, said: “It is almost impossible to define the enormous value of our hedgerow network – just as our arteries and veins supply our bodies with nutrients and oxygen, the UK’s hedgerow network defines many of our rural landscapes and must remain healthy to benefit villages, towns and cities. Our research shows that investing in our hedgerows is a win-win for climate and people in both the countryside and urban areas. “But we know the government has the biggest part to play in unleashing the full potential of hedgerows. That’s why we’re calling on ministers to set a target to increase the hedgerow network by 40 per cent by 2050 with improved protection for existing hedgerows. In its expanse, the hedgerow network is our largest, most connected, ‘nature reserve’. Healthy hedgerows are teeming with life and vital for nature. One in nine of all vulnerable species in the UK are associated with hedgerows. These include the hazel dormouse; the hedgehog, whose decline has been closely associated with hedgerow loss; and the brown hairstreak butterfly, which lays its eggs on blackthorn and is particularly common in hedgerows. Lord Deben, chair of the Climate Change Committee, said: “What was a determination to make land more productive in order to feed our people during and after the war has led to indiscriminate destruction of our hedgerows. Spurred on by Deficiency Payments and the Common Agricultural Policy, our yields rose and our wildlife diminished. “Reintroduction and proper maintenance of hedgerows transforms the all too sterile prairie land into the countryside, which for long we have loved. But, as this report shows, this is not about romance – the hard facts are that hedges contribute to profit as well as to well-being.” There is a parliamentary launch of our hedgerows campaign this afternoon, hosted by MP Selaine Saxby.
They are one of the most familiar features of the Kent countryside. We find them lining roads, railways and footpaths. We see them bordering fields and gardens. But hedgerows are under threat from poor management practices and development pressures and many have been removed.
Hedgerows originally defined ownership boundaries and provided shelter and stock-proof barriers between fields. They also helped reduce soil erosion and surface-water run-off on arable land. The hedgerows from this later period tend to be straight and dominated by hawthorn, while those from medieval times include field maple, hazel, dogwood and spindle, which provide richer habitats for mammals, birds and insects.
But aren’t hedgerows protected?
Strong controls exist for the protection of hedgerows in the open countryside. The Hedgerow Regulations 1997 prohibit the removal of ‘important’ hedgerows unless at least 42 days’ notice is served on the local planning authority and it has either granted such permission or failed to serve notice preventing removal.
For a hedgerow to be regarded as important, it must satisfy criteria relating to its size and age:
• It must be at least 20 metres long, or, if it is less than 20 metres, meet at each end another hedgerow (any gap of less than 20 metres is treated as part of the hedgerow)
• It must be at least 30 years old and part of a historic parish boundary or a medieval estate or manor boundary, or part of a field system that existed before 1845, or
• It must contain, or be next to, archaeological features and sites such as scheduled monuments, or
• The hedgerow contains protected wildlife or plants and associated features
However, the situation regarding hedgerows and hedges in built-up areas, or where the countryside meets the built-up area, is much less helpful in their protection. Generally speaking, a hedgerow is not protected if it is in or marks the boundary of a private garden.
There are exceptions to this:
• If a hedgerow is in a Conservation Area, removal may require permission if it includes trees
• A hedgerow may be protected if it includes trees covered by a Tree Preservation Order (although the protection only relates to the trees, not intervening shrubs)
Hedges can also be protected, to a limited extent, through conditions attached to a planning permission or through legal covenants attached to a property, though this would be dependent on enforcement in both instances.
What else can we do to protect our hedgerows?
Firstly, we could lobby for Local Plan policies that give a measure of control over the removal of hedgerows. An example of where this has been done relates to the criteria attached to Ashford Local Plan Site Policies S51 and S52 in Aldington. These require retention of a hedgerow that originally formed a field boundary as part of any edge-of-village residential development…
“The site is proposed for residential development with an indicative capacity of 12 dwellings. Development proposals for this site shall: (a) Be designed and laid out in such a way as to conserve the mature hedgerow along the road frontage where possible…”
Secondly, in addition to lobbying for hedgerow protection on specific development sites in Local Plans, we could press for hedgerows to be covered in Supplementary Planning Guidance and in Neighbourhood Plans. An illustration of this is the Vale of Glamorgan’s Supplementary Planning Guidance for Trees, Woodlands and Hedgerows produced in 2017. This requires that where developments are likely to affect a hedgerow, a survey must be undertaken to ascertain whether the hedgerow should be classified as important under the Hedgerow Regulations 1987. The survey is required to cover the condition, height, spread and species content of the hedgerow. Even when the hedgerow is deemed not to meet the criteria for classification as important, consideration is to be given to its importance for biodiversity and wildlife, for example as nesting sites, migration corridors or foraging routes for bats and birds, or as habitat for dormice. The Guidance requires building layout and site infrastructure to be designed so that as many hedgerows as possible are retained. Thirdly, we could address hedgerow protection at planning-application level. We could encourage landowners and prospective developers to incorporate established hedgerows into their landscaping schemes when sites come forward for development. Fourthly, we could do more to get the public on our side and to value the hedgerows in their areas. Ironically, the only specific legislation applying to urban hedgerows concerns their potential nuisance and neighbour disputes about hedgerows between property boundaries. The Anti-social Behaviour Act 2003 addresses how neighbour disputes over hedges should be dealt with. We should be doing more to publicise the value of hedgerows and good management practices so that a better-informed and sympathetic public would be more prepared to accommodate them. Hedges are good for our health. They hold particulates from traffic fumes and tyres that would otherwise end up deep in our lungs. Studies have shown that a one-metre-long hedge traps emissions from 30 diesel cars a year. Being at street level, they are more efficient at trapping exhaust pollution than trees. The best hedges in this regard have many small leaves and are evergreen. An ill-informed public could be doing harm to wildlife without knowing it. Under the Wildlife and Countryside Act 1981, for example, it is an offence to disturb a bird’s nest if it contains eggs or chicks or is being otherwise used; such a nest could of course be in a hedge. Hedgerows are beautiful, they are beneficial in so many ways and they can be packed with wildlife – let us share and publicise their value for the benefit of future generations.
CPRE, the countryside charity, has joined with other major charities to call for urgent action to extend the country’s hedgerows by 40% by 2050 to protect nature and help tackle the climate crisis. Our humble hedgerows are the unsung heroes of the countryside. They have been adding beauty and character to our landscapes for centuries while providing the food and shelter that sustains our wildlife. They protect the soil, clean the air and absorb carbon emissions. But we have lost about half since 1945. Now, as we face up to the climate emergency, we urgently need to start reversing that decline – and allow our hedgerows to play their most important role yet. That is why we have launched our #40by50 campaign, calling on ministers to commit to extending the hedgerow network by 40% by 2050, as recommended by the independent Climate Change Committee, and have written to the government to this effect, as published in The Times last month. Our open letter calling on the government to do more to extend hedgerows reads as follows:
Hedgerows: the climate and nature heroes
Tree planting and peatland restoration are important parts of the government’s plan to tackle the climate and nature emergencies. Yet there is still one powerful solution missing from its strategy: the humble hedgerow. Hedgerows are the unsung heroes of our countryside. They are icons of our landscape, steeped in history, providing a haven for wildlife while absorbing carbon emissions. The hedgerow network, in its expanse, is our largest ‘nature reserve’. Shockingly, it is estimated that more than half our hedgerows have been lost since WW2, and many existing hedgerows are in a poor, degraded state. The Climate Change Committee recommends extending the hedgerow network by 40% by 2050 to help achieve net-zero. Ahead of COP26, now is the time for Ministers to show real leadership by committing to this target, while restoring our existing hedgerow network, to deliver a more resilient, beautiful and biodiverse countryside.
