Let Ryevitalise begin!

Alex Cripps – Ryevitalise Programme Manager

For the last two years we have been leading on the development of Ryevitalise, a landscape partnership scheme focusing on the River Rye and its tributaries.

So we are really delighted to report that we were successful with the final Stage Two application to the National Lottery Heritage Fund and have been awarded nearly £2 million towards the delivery of this fantastic four-year scheme – starting now.

With match funding included Ryevitalise is a £3.4 million programme in total, focusing on three key themes:

  • Water quality and the environment – restoring and conserving the aquatic habitats of the Rye and the rare and threatened species that the river and wider landscape supports;
  • Water Level Management – harnessing natural flood processes to create a more naturally functioning river; and
  • Reconnecting people – improving the understanding of the river landscape by telling the story of its evolution and encouraging people to protect their heritage.

Ryevitalise is very much a partner-led scheme with over 15 organisations working together to deliver their common goals across this part of the River Rye catchment. The River Rye and its tributaries meander through a variety of landscapes including moorland, upland farmland and lowland arable and livestock farmland; crossing over the National Park boundary into the Howardian Hills Area of Outstanding Natural Beauty (AONB) and into the non-designated wider Ryedale beyond. It’s a wonderful opportunity for us to work closely with partners like the the Howardian Hills AONB, Ryedale District Council and the Environment Agency.  The North York Moors National Park Authority itself is the lead partner and we’re currently recruiting the delivery team.

I’ve recently been appointed as the Ryevitalise Programme Manager and I’m really excited about this amazing opportunity to share my enthusiasm for rivers and the fascinating wildlife that the freshwater habitats and the surrounding areas support. One of the main goals is to reconnect people with nature and our river environments. I am really keen to raise the profile of rivers by looking at how valuable these ecosystems are, and how important they are to people both within the Ryevitalise area itself but also beyond. Over the next four years we will be working alongside local communities, including land managers and young people, reconnecting people to their local river systems and exploring how simple every day actions to help care for our rivers can collectively make a huge, positive difference.

There will be lots of opportunities to get involved, from practical conservation tasks such as Himalayan balsam control to species monitoring. There will also be a programme of expert talks, exhibitions and discovery events. Keep an eye on social media, our website or this blog for further updates once the new team are up and running.

If you are keen to get involved at the start please get in touch, perhaps you are a member of a local community group wanting to know more, a local land manager interested in improving water quality, or you would like to sign up as a Ryevitalise Volunteer – it would be great to hear from you!

What to do on a Sunday …

David Mennear – Land of Iron Administration Assistant

This coming Sunday the Moors National Park Centre at Danby (YO21 2NB) is hosting a family friendly fun day to celebrate the brand new immersive experience on offer. With funding from the National Lottery’s Heritage Fund and the David Ross Foundation, the Land of Iron Landscape Partnership Scheme has been helping to reinvigorate the interpretation resources at the Visitor Centre over the last few months.

Escape to the Moors is taking place on Sunday 21 July from 11 am until 4 pm. The event will celebrate the people and the natural and historical heritage of the North York Moors through workshops, family attractions and children activities all taking place in the grounds of the Moors Centre; whilst the Centre itself will be open for everyone to have a look at the new interpretation.

The new interpretation features the beauty and significance of the North York Moors, alongside the ironstone mining heritage of the area. The ironstone mining period was an era of rapid industrial growth in the 19th and early 20th centuries that saw the workings of the railways, mines, and huge calcining kilns in the heart of the North York Moors itself. For years the mined ironstone was refined and transported away to be used in construction projects across the world, helping to cement the industrial growth of Britain during this recent period of history.

Using the latest digital technologies and archaeological and ecological techniques, through our innovative interpretation we are helping to present the historical and natural heritage of the North York Moors for a new audience. You might be surprised to see how fast built heritage can quickly disappear back into nature once again, just leaving traces to be discovered.

This is what’s coming up on the day:

  • The trailblazing Land of Iron tells the story of ironstone and railways in the North York Moors – build an ironstone foam bridge, excavate at a mini-dig, learn about industrious Victorians and handle artefacts, tackle the 3D jigsaw puzzle and lots more.
  • Whilst the Cleveland Ironstone Mining Museum in Skinningrove is closed for refurbishment the team will be bringing their incredible pop up museum to the Moors Centre. Celebrate the history of a long lost industry and the stories of the everyday people involved as you travel down a make shift mine tunnel.
  • Our Moors and Valleys Young Archaeologists’ Club officer will be there to let you know about the exciting activities the Club gets up to.
  • Through the Rosedale History Society learn all about how the small and sleepy medieval village of Rosedale Abbey drastically changed as it thundered into life during the industrial revolution as ironstone mines and calcining kilns appeared around the Rosedale hills and dale. Now known for its bucolic countryside beauty and isolation, Rosedale was once a beating heart of British industry on the international stage.
  • Experience history with the wonderful living history and reenactment group Rosa Mundi – there’ll be medieval spear practice and military drills as well as trying out candle-dipping and other traditional crafts along with games and cooking demonstrations.
  • Be digitally dazzled as Adrian Glasser presents his amazing Time Sliders where historic photographs blend into the modern landscape – learn all about 3D modelling with an introduction to photogrammetry and how this incredible technique is capturing key Land of Iron monuments for the future.
  • Cleveland Fibre Arts will be demonstrating how ironstone helps to give wood and felt-making distinctive colours and patterns. Join in and help make your own!
  • Join the Whitby Company of Archers to have-a-go at archery and discover your inner Robin Hood (charges apply).
  • The Teesoutdoors Climbing Tower will be on site and as well as climbing the tower under the expert guidance of the qualified instructors, you can pick up climbing tips and find out the best places to climb in the North York Moors (charges apply).
  • Ride the Grosmont Velocipede around the Moors Centre grounds – have you ever tried a velocipede before? why not give it a whirl on a 100ft of rail track as members of the team push you around! It might just be the oddest thing you do that Sunday.

Apprentices go all-a-Broad

Lisa Till – Coast Area Apprentice Ranger

At the end of May, six of us North York Moors National Park Authority’s Apprentices got the fantastic opportunity to take part in an Apprentice Exchange in the beautiful Broads. After a long drive down to the village of Coltishall, we received a lovely welcome at the Girl Guiding Lodge we were staying in from the Broads Apprentices who were hosting us. After a lot of introductions to the apprentices from the South Downs, Yorkshire Dales, and the Broads, the evening was filled with presentations from each National Park along with a plentiful BBQ arranged by Graeme and Polly, the Broads Rangers who had organised the whole trip.

On the next morning we all headed out first thing to Geldeston, where we met up with more Rangers from the Broads and went on a canoe trail along the River Waveney to Beccles. Out in the canoes for an hour and a half, we found that the best way to experience the Broads is definitely by boat. Our trail took us along a lovely tranquil stretch of river, showing us just a glimpse of the great scenery and wildlife there is on offer. The trip on the water also gave us chance to learn about the responsibility the Broads Authority has to maintain the navigation, along with stories of speeding boats and the inevitable accidents that occur. Back on dry land, and with only one canoe having capsized, we headed back to the minibus and on to our next adventure.

After a lunch break, where we were lucky enough to spot a Long-Eared Bat, we were taken on a guided walk by Ranger Stephen Fairbrass around part of Hickling Broad. Hickling Broad, like most of the Broads, is a result of peat digging in the 12th to 14th centuries where the area then flooded due to sea-level rise, an issue the Broads are continually facing. We were shown the last working Eel Sett in the east of England at Candle Dyke, and we spotted a Chinese Water Deer and saw the Konik ponies; both species graze the area.

After a fantastic home-made lasagne for tea back at the base, we were out again onto the waterways for a trip on the solar powered boat ‘Ra’ on the Whitlingham Great Broad at Whitlingham Country Park. We had a fantastic hour trip, and Captain Mark told us all about the fascinating history of the area and its wildlife. ‘Ra’ was Britain’s first solar-powered passenger boat, and with the City of Norwich so close if offers a great chance to view wildlife of the Broads so near to the city.  We all ended up in Norwich for a brilliant end to the day for a pub quiz at the Fat Cat Pub. Other employees of the Broads Authority joined us for additional brain power, but unfortunately even with around 20 of us we still didn’t manage to beat the locals.

Thursday began bright and early and we were all straight out to meet Volunteer Pete Morgan at St Benet’s Abbey, which 1000 years ago was a prosperous monastery. Pete gave us a brilliant guided tour of the Abbey remains and the setting. Back in Tudor times when King Henry VIII closed down monasteries across the country, St Benet’s remained the only one never officially shut down.

We left the Abbey on foot and walked towards How Hill along the River Ant – what with the sun shining, an ice cream stop was definitely in order. At How Hill we looked around Toad Hole Cottage, a traditional Marshman’s Cottage. There used to be plenty of Marshmen in the Broads, working across vast areas cutting and collecting reeds whilst managing the land with drainage and cattle. However, the growth of machinery has meant this way of life has slowly died out; the cottage at How Hill still shows how these families used to live and work.

As no trip is complete without a trip to the beach, so next we headed out to the coast. The beach at Horsey Gap gave us a chance for a paddle (even a dip for some). It is well known for its grey seal colony and we spotted some friendly seals popping their heads above the water. We soon had to head off again this time to Brandeston Village Hall to see a local theatre production called ‘Tide Jetty’. The play was a dramatic love story reflecting life growing up in the Broads, which was a perfect way to end our time spent together.

As Friday morning came we all said our goodbyes over our final breakfast together, before heading back to our own National Parks. The trip was a great experience to see another National Park whose landscapes and challenges are different to the North York Moors. As our National Park Authority has had apprentices for many years, the Apprentices and Rangers at the Broads were interested in how our programme runs and we all learnt a lot about the range of apprenticeships on offer. Our North York Moors group had apprentices from planning, tourism, and the ranger services which shows the diverse apprenticeship opportunities available. A big focus of the trip was to remind us all that although we work all over the country, we’re all part of one ‘National Park Family’ and it is always good to discuss ideas and to praise and support each other whenever possible. Huge thanks to Graeme, Polly, and everyone else who helped from the Broads Authority for being such brilliant hosts and showing us all the best bits that the Broads has to offer.

Seeds for the future

Alasdair Fagan – Woodland Creation Officer

In a previous blog, on the Year of Green Action, we mentioned the planting of 3,500 trees near Danby by National Park staff and volunteers. Our volunteers form an integral part of the work we are able to do, this is particularly the case with woodland work.

Last year saw the origins of the Acorn Volunteer Group. The task for this Group is to collect tree seed from the ancient woodlands and trees of the North York Moors to then be propagated and grown on at local tree nurseries with the ultimate aim of the trees being used in future woodland creation schemes throughout the area.

We focused in the first year on acorns as the National Park Authority has a bit of a history of acorn collecting and so we already knew some good spots to try. We managed to collect over 25,000 acorns. Going forward we are looking to diversify the tree species we collect to include species such as rowan, elder and wild cherry.

So why is collecting tree seeds important?

There are ongoing discussions in the world of woodland and forestry about what is the best approach for new woodland planting – whether it should be young trees grown from seed which has been collected from the local area (‘local provenance’) or trees grown from seed sourced elsewhere in the country e.g. further south.

Local provenance seed has benefits such as being from trees which we know grow well on a kind of site or in a particular area , but seed from a more southerly zone has the potential to be better suited in the future because of an increasingly warming climate.

The predictions for climate change vary in severity based on the potential for carbon dioxide and other greenhouse gas emissions, but what is certain is that our summers will be warmer and drier (this is especially true in the east of the Britain) and our winters will be wetter. This means that the climatic conditions of the places where we are planting trees today to create woodlands could be significantly different in 100 years time. 100 years is not a long time within the lifetime of a woodland. Woodland managers need to consider the effects of their work over these long timescales. Planning now to survive the effects of climate change is essential to give our woodlands the greatest chance of reaching maturity.

Ayton Banks. Stitchwort and bluebells growing on a site with newly planted trees. These woodland indicator plants grow on woodland soils and show where woodlands once existed. Copyright NYMNPA.Currently the advice for woodland managers is that the best approach depends on the characteristics of the site proposed. On sites where the woodland soils have remained relatively undisturbed, with intact woodland plant communities – such as bluebells and wood sorrel – planting local provenance trees is still the best choice, particularly if it is adjacent to an existing ancient woodland. However if the site is less sensitive then it makes sense to try and improve the woodland’s chance to withstand the effects of climate change and the resulting pests and disease as much as is possible; making the woodland more ‘resilient’.

This type of resilience is increased by having a higher number of tree species as more diversity means that any one pest or disease is unlikely to have a catastrophic effect on the entire wood. If you also incorporate into this diverse mix of tree species a mix of genetic stock, such as you would get from planting a mixture of trees sourced both locally and from further afield, then this is certain to improve a woodland’s chances of adaptation and survival in the future.

Setting up a seed collecting project is a way to make sure we have some locally sourced trees to plant, including some of the genetics of our oldest living trees. The project is also a great way to include volunteers and give them the opportunity to visit some of the ancient trees and woodlands hidden away in secluded parts of the North York Moors.

Looking forward to June

David Mennear – Land of Iron Administration Assistant, and Sam Newton – Sam Newton – Land of Iron Natural Heritage Trainee

Surrounding the remarkable built heritage remains of the Land of Iron is a patchwork of habitats and species that have withstood the industrial exploitation and managed to find a niche in the landscape left behind. The Land of Iron Landscape Partnership Scheme, supported by the National Lottery’s Heritage Fund, is working to maintain these habitats and species. Ancient woodland, upland hay meadows and salmon rivers are being enhanced, and by addressing gaps between good habitat the connectivity through the landscape is improved helping wildlife move more freely.

To celebrate the natural heritage of Rosedale, one of the key areas of the Land of Iron, a free to attend Wildlife Week is happening from Sunday 23 to Sunday 29 June 2019. The Updale Reading Room (YO18 8RQ) in Rosedale will be the main hub but there will be activities taking place across the dale. This family-friendly week will be full of opportunities to learn all about the remarkable animal and plant life right here in the North York Moors.

Join us during our Wildlife Week as we celebrate the natural heritage of Rosedale by encountering a wide array of habitats and species under the guidance of local experts. By identifying and recording what we find during the week you will be helping to further understand, and therefore help protect, the diverse wildlife of this area of past ironstone industry into the future.

The kind of things that are going to be happening include:

  • Aquatic Rosedale – spend the morning visiting some fantastic wildlife ponds and the afternoon identifying aquatic invertebrates;
  • Bats of the Abbey – stay out till midnight to see what happens after dark in Rosedale Abbey village, guided by a local bat expert;
  • Fabulous Flora – learn to recognise wildflowers and grasses in the historic Rosedale Abbey churchyard;
  • Moth Mornings – a great way to discover some of the 2,500 species we have in the UK;
  • Tantalising Talks – from photographing wildlife to goshawks and humpbacks, listen to our experts share their experiences in the wild;
  • Rosedale Abbey Short Nature Walk – a short nature and history-themed walk, accessible to all around Rosedale Abbey village;
  • Wildlife Walks – wildlife-themed walks visiting hidden Hartoft and up-dale Rosedale.

The Madness and Delight of a North Yorkshire forest at dawn   

Getting up at 3am to start a bird survey at dawn deep in the North Yorkshire countryside may seem like madness to many people but for Ginny the delight has been far greater than the sacrifice…

North Yorkshire Turtle Dove Project logo

Ginny Leeming, Turtle Dove Volunteer

A few years ago I was walking in Broxa Forest when I became aware of a strange low bubbling, turring sound. For a minute I just couldn’t place it – perhaps a frog? Then it clicked – I hadn’t heard it for years but it had once been so familiar to me. I went home and looked up some facts and figures and was horrified (though not entirely surprised) to learn of the drastic fall in numbers of a bird that was once so well known (and still is widely known by name if only through the 12 Days of Christmas). So when I heard about the Turtle Dove Project I was immediately keen to get involved. OK, so getting up at 3am to be in the forest ready to start a survey at dawn is somewhat daunting, and I even felt a bit nervous at the thought of walking through the forest in semi-darkness. But once up it is a truly magical time to be out there. I’ve had close encounters with badgers, deer, hares and much other wildlife.

On my very first survey I was nearing the end, almost resigned to a negative result, when I approached a clearing and before I could see through the trees I heard that unique sound. It turned out to be 3 singing males. I really had to stop myself shrieking with delight! Since then I’ve had less luck, but the memory of that moment has helped to maintain my feeling of anticipation. It has also been really encouraging to know that the data from that first survey has already been used to target conservation measures on local farms. Perhaps in a few more years encounters with these iconic birds will become more common.

Our North Yorkshire Turtle Dove Project surveys start again in May. We will be holding two meetings this spring to explain the surveys and to allow volunteers to meet up. One meeting will be in the Dalby Forest Courtyard Building (YO18 7LT) on 24 April at 7 pm and the second at the Yorkshire Arboretum (YO60 7BY) in the Howardian Hills on 2 May, again at 7 pm. If you’d like to get involved please come along or alternatively email Richard Baines, Turtle Dove Project Officer.

A to Z: a troupe of Ts

TEMPLARS

Most people have probably heard of the Knights Templar, mediaeval military monks best known for their Order being forcefully suppressed.

The sole purpose of the Order was to protect pilgrims, and that meant supporting knights in the Holy Land which required money. Along with many monastic orders the Knights Templar were good at making and managing money to fund themselves and their work. Nobles were particularly happy to endow military orders with gifts and property as a way to win favour with God, because they shared a common interest in the noble art of fighting. A mix of Papal and Regal authority granted the Templars immunity to local jurisdiction and taxation, putting them beyond the law.

The Templars were pan European and had a network of estates in England. One of these holdings was the Manor of Westerdale in the north west of the North York Moors, which was gifted to the Knights Templar in 1203 by Guy de Bonaincurt. There are also records of additional gifts from other landowners in the wider area, at Kildale, Ingleby Arncliffe, Pinchinthope, and Broughton. At Westerdale a preceptory was founded – a preceptory is a military order’s equivalent of a monastery – and the land put to good use producing income. It’s not known where the buildings and granges were, suggestions include Westerdale Hall and there are earthworks at two sites towards the head of the dale. 

The Knights Templar Order consisted of Knight Brothers (you had to already be a knight), Sergeants/Serving Brothers, and Chaplains. Then there were the lay servants to do most of the work. There wouldn’t have been knights at Westerdale, but there would no doubt have been servants farming the land. When the Order was surpressed the Manor was recorded as being 1,182 acres and producing £37 of annual income.

The Order didn’t long survive the end of the Crusades in the Holy Land. Pope Clement V issued a bull in 1307 telling all Christian monarchs in Europe to arrest Templars and seize their assets. The dissolution in England was drawn out and non-violent. The Manor of Westerdale was taken by the crown in 1311 or 1312 and then held until it was either given or sold to the Knight Hospitallers (the other major military order) in 1338. Two hundred years later it went back to the crown during the Reformation..

TEMPLE MOORE (1856 – 1920)

The fantastically named Temple Lushington Moore was a celebrated Victorian/Edwardian architect, particularly renowned for his ecclesiastical commissions both inside and out. He conceived new churches* and restored/rebuilt churches**, many of which are now listed. He also designed decorative church fixtures such as screens, windows, reredos, lecterns, and pulpits.

Moore’s style was Late Gothic Revival with its focus on the mediaeval: for example pointed arches, buttresses, vaulted ceilings, ornamentation and decoration.

There was a lot of new building/rebuilding of Anglican churches at this time; to serve the growing urban populations and to rival the pull of the evangelical low church congregations. The Gothic Revival style linked directly with the high church tractarian movement at the end of the 19th century. The exaggerated style presented an idealised medieval past in reaction to mechanisation and industrialisation. The enthusiasm for the style itself could sometimes result in the destruction or diminishing of original mediaeval elements of the buildings being ‘restored’.

Temple Moore worked on a number of commissions in and around the North York Moors and elsewhere in Yorkshire which earned the appellation for his work of ‘gothic with a Yorkshire accent’.

TREE PRESERVATION ORDERS

The North York Moors has a statutory claim to fame, because one of the first Tree Preservation Orders in England was served in the village of Sinnington. It was served to protect an area of woodland known as The Stripe to the north of the village. It was an ‘interim’ TPO made under the Town and Country Planning (Interim Development) Act of 1943.

This Act was followed up a few years later by the Town and Country Planning Act 1947. This legislation looked to build a new country, depending on receiving permission. It aimed to control development and protect the best elements such as buildings with special architectural or historic interest as well as trees and woodland, the natural equivalent of the buildings. Where trees or woodland might be under threat and those trees or woodland had an identified amenity value – that is they mattered to local people and the wider landscape – a Tree Preservation Order could be served. Also in 1947 came the Hobhouse Report which recommended the creation of National Parks; however the thing about Tree Preservation Orders is they can be used anywhere not just in protected landscapes, because any tree can be special.

Tree Preservation Orders are still a useful part of planning legislation, most recently reiterated in the Town and Country Planning (Amendment) Act 2012.

TREE SPARROWS

Many people would recognise the House Sparrow (Passer domesticus), a common visitor to garden bird tables and feeders. Less often seen is the smaller Tree Sparrow (Passer montanus), a shyer bird that can be distinguished by its chestnut brown cap and black cheek spots.

The Tree Sparrow has suffered a substantial decline in recent decades with a 93% population decrease between 1970-2008. They are therefore on the Red List for conservation concern.

Tree Sparrows make use of cavities in trees and old buildings to nest in. They will also build their own nests within thick hedges. During the 1970s and 80s many elm trees were lost to Dutch elm disease which reduced the availability of nesting holes for this and other species. Alternatively, they will make use of nest boxes – projects aiming to expand Tree Sparrow populations place several nest boxes close together as the birds like to live in colonies.

A good habitat for Tree Sparrows is mixed farmland where small woodlands, scrubby hedgerows, cereal crops and dead trees can be found together. Aquatic invertebrates are a good food source for their young so farmland ponds are also valuable features. Young chicks are fed on insects to provide them with the minerals they need to develop their bones. Seeds and cereals, such as wheat and barley, are also part of the Tree Sparrow diet.

The southern edge of the North York Moors is a good area for Tree Sparrows, villages such as Hackness, Staintondale, Newton-upon-Rawcliffe and Lockton all have Tree Sparrow populations.

TWAYBLADES

There are two types of Twayblades: Common Twayblade (Neottia ovata) and Lesser Twayblade (Neottia cordata). These are orchids, not the blousy bright orchids but much more subtle and discreet.  Both have one upright stalk with small clusters of flowers at the top. The Common Twayblade has tiny yellow/green flowers and can grow up to 60 cm tall, the Lesser Twayblade has tiny reddish flowers and grows up to 20 cm. The name Twayblade comes from Old English words for two leaves, because Twayblades have one pair of leaves except sometimes they don’t, sometimes there is a third leaf. Common Twayblade are much more adaptable than Lesser Twayblades, growing in neutral/calcareous grassland and woodland. Lesser Twayblades favour acid soil so are found in wet Ancient Woodland and on wet heath. They’re pollinated by tiny insects e.g. flies for Common Twayblade, even smaller gnats for Lesser Twayblade. They both smell, however whereas the Common Twayblade has a gentle sweetish smell, the Lesser Twayblade produces a smell like rotting flesh which humans find unpleasant but gnats like. Both plants produce tiny seeds like dust, but they can also spread through rhizomes from their roots. As well as diminishing habitat, one of the other reasons for Twayblades being relatively rare is because they take such a long time to grow up, it can take a Common Twayblade 15 years to mature enough to flower.

Hedgerow equations

Large parts of the North York Moors have either no field boundaries (open moorland) or have drystone walls as boundaries (upland tops and slopes), but round the edges of the area and in the farmland dales there are often hedgerows. A large number of these hedges will have existed for years, but they’re not considered ‘ancient’ unless they’re older than 1700, just like Ancient Woodland.

Hedgerows of course are made out of trees and shrubs just like woodland but are otherwise culturally and ecologically distinctive. Hedgerows have long been a man-made feature of landscapes – boundaries to keep things in as well as out. In other parts of England there are hedgerows that are thought to date back over a millennium. This is not so likely in the North York Moors. Many hedgerows here probably just date back to the 18th and 19th centuries when there was a lot of enclosure and land ‘improvement’ going on, here as elsewhere in the country.

Old roadside hedgerow, Bilsdale. Copyright Ami Hudson, NYMNPA.

Hedgerows have been created through one or more of these three methods – original planting/transplanting, allowing uncultivated field edges to grow up, or by leaving a ‘ghost’/edge of a removed woodland. A curved hedge suggests a ghost hedge because natural woodlands are more likely to have had curved not straight edges, whereas constructed boundaries are often as straight as possible.

Ancient hedges share Ancient Woodland herbaceous ground flora such as Wood anemone, Sweet woodruff and Golden saxifrage. There is also a well-known ‘rule’ (Hooper’s Law) sometimes used to estimate the age of a hedge by counting the number of established woody species over a 30 yard/30 metres stretch or preferably an average over a series of stretches. The equation is then Age = no of species in a 30 yard stretch (or average number) x 110 + 30 years.

Whereas an enclosure hedge (18th/19th century) will have one or two species, a pre Norman Conquest hedge might have more than ten species. However such ancient hedges would have been an unlikely feature in the ‘wastes’ of the North York Moors recorded in the Domesday Book at the end of the 11th century.

Managed hedgerow, Glaisdale. Copyright NYMNPA.

Like all rules there is bound to be exceptions. Hooper’s Law relies on the hedgerow being mainly naturally colonised, not planted 30 years ago by a biodiversity enthusiast. Also any hedgerow adjoined to or close-by woodlands are more likely to be colonised at different rate than another hedge. In the end it’s probably best to use other evidence of dating, such as maps and records, as well.

Although original hedgerows may have been planted and laid to incorporate existing older trees it would be difficult to keep such trees alive, and therefore much more likely that in-boundary trees were planted at the same time as a hedge or added later. The first edition Ordnance Survey 25 inch mapping includes individual in-field and in-boundary trees. For the North York Moors area these maps are usually from the 1890s. The presence of a mapped in-boundary tree suggests that boundary was a hedge rather than wall or fence at that time.

Since the middle of the 20th century the amount of hedgerow in the country as well as the number of boundary trees has been reduced. Machinery meant it became easy enough to remove a hedgerow, and to maximise the cutting of hedgerows. At the moment the cultural and ecological importance of hedgerows is valued and lately there have been efforts to use agri-environment schemes to encourage good practice management and to use the 1997 Hedgerow Regulations to control removal.

* This is the list of species which count towards Hooper’s Law. The species listed grow in a wide variety of habitats across the country, only some of these would ever have been used in and around the North York Moors. As it is currently winter, identifying different species is particularly difficult and therefore maybe more fun.

The BIFFA funded project ‘Restoring Freshwater Mussel Rivers in England’ came to an end in 2018. We were involved because of the River Esk in the north of the National Park. The £300,000 made available helped towards safeguarding Yorkshire’s last remaining population of Freshwater pearl mussels (Margaritifera margaritifera).Image of the River Esk, August 2013.

A huge amount of work was achieved in the Upper Esk catchment during the three year period of this project, working closely with the farming community to address diffuse pollution from agriculture. Pollution including sedimentation detrimentally affects water quality and therefore impacts on aquatic species like the mussels.

For most of its three years the project was led by Simon Hirst, our River Esk Project Officer. Simon worked with 38 land managers in the Upper Esk catchment delivering improvement works to help keep pollution including sedimentation out of the river and its tributaries. This has meant:

  • Over 8km of riparian fencing installed
    This helps stabilise the river banks and creates buffer strips to reduce the amount of runoff from fields getting into watercourses, as well as providing rough habitat along the river corridor for insects which are so important for fish, birds and small mammals.
  • 650 trees planted along the river banks of the Esk and its tributaries
    The majority of which were planted by our dedicated River Esk Volunteer Group.
    Trees help stabilise the banks and so. like with the fencing, reduce sedimentation.
  • 34 alternative watering points installed
    This is to reduce poaching in fields and along the river banks, and to keep stock and their effluent out of a watercourse.
  • Approximately 5.5km of riverbank re-vegetated with woodrush planting
    Another 130m of river bank was stabilised using hazel/willow whips. Re-vegetation helps stabilises the river banks
  • Over 500m of guttering and downpipe installed on farm buildings
    To capture clean water before it gets onto the ground, picks up nutrients and sediment, and then runs into a watercourse.
  • 1,237 m3 of concreting in farm yards.
    The new surface is profiled to collect dirty water before it can enter a nearby watercourse.

Big Thank You to Biffa for supporting the Restoring Freshwater Mussel Rivers in England project.

Big Thank You to all the local land managers who worked alongside Simon on the Esk, contributing a lot  of their own time and capital to complete these improvement works.

Big Thank You to our dedicated Mussel Volunteers who have played such a vital role in this delivery project, and all the other volunteers that helped out like the Explorer Club and the 1st Marston Moor Scout Group.

And one more Big Thank You to Simon Hirst. Last year the North York Moors National Park had to say goodbye to Simon because he moved on to a new role working on the River Holme in Huddersfield. His enthusiasm and knowledge will be greatly missed by us and the Esk’s Freshwater pearl mussels.
