Banque, hedgerow and tree management. Branchage guidelines updated

By Cassie Horton with Dru Burdon and Dom Wormell

A meeting was held last August last year at the request of Dru Burdon from the Jersey Hedgehog Preservation Group as she was so frustrated and upset at the number of hedgehogs coming in with severe injuries. That meeting was attended by about 20 individuals/environmental organisations together with the Natural Environment Department, the Comité des Connétables and the Jersey Farmers’ Union to revise the branchage practice for the benefit of the Island’s fauna and flora. It was proposed that a small committee be formed to identify how we could improve the situation and myself together with Bob Tompkins, Neil Singleton, Alli Caldeira, Dru Burdon, Rose Anne Mitchell and Chris Perkins put our hands up! We are by no means experts in land management but we have endeavoured to seek advice and input from those in the know. Over recent months we have rewritten the branchage guidelines and hope that the revised version will be easier to understand with clear examples of photos and a diagram of best practice.

A training session was organised on 30 May and hosted by Peter le Maistre, the President of the Jersey Farmers’ Union attended by about 50 farmers and contractors, representatives of environmental organisations and John Pinel, Principal Ecologist and Assistant Director of the Natural Environment Department. It was a very successful event with honest and constructive dialogue between all concerned. One of the farmers stated that this was the first time environmentalists and farmers had come together to discuss these issues and this process should continue as it had been incredibly helpful and positive. He also suggested that results of wildlife monitoring (as a result of the new branchage regime) should be reported back to the farmers.

Peter Le Maistre and Ian Le Brun (Jersey Royal Potato Company) had earlier that week cut three examples of branchaging to demonstrate to those present and provide an opportunity for discussion and a compromise was agreed whereby the lower part of the banque is cut to a minimum height of 10cm but the top is left uncut, as this will give wildlife a chance of survival but still adhere to the branchage law. Revised guidelines on best practice for hedgerow, tree and banque (bank) management have now been agreed and will be published by Natural Environment.

Alastair Christie, the Asian Hornet Coordinator also gave a presentation on signs to look out for when undertaking the branchage process and safe working practices.

Our farmers have a symbiotic relationship with the landscape and the large majority of them (particularly those present at the meeting) consider themselves every bit as much an environmentalist. The planting of trees and hedgerows by farmers over the years has contributed to the health of our countryside and they are supportive of improving the biodiversity of our banques and hedgerows.

The Branchage Law dates back to 1914 when the aim was to improve the safety for road users and pedestrians. This is still the case today, however, a misunderstanding/misinterpretation of the law has been allowed to happen and this idea of a ‘neat and tidy’ landscape needs to be done away with. The law is very specific and, as long as a height of 3.7 metres above roads and 2.4 metres above footpaths is adhered to, then the Connétables are happy with this. The banques do not need to be cut down to the bare soil and, as long as vegetation does not overhang the road/footpaths, then the tops can be left uncut. This will allow the desired vegetation to seed but, more importantly, the protection of animals such as hedgehogs, lizards, slow worms and fledgling birds.

Work needs to continue in making private landowners and landlords aware of the new guidelines. Some tenant farmers have been told they risk having fields taken away from them if they don’t make everything ‘neat and tidy’ and it is disheartening when they adhere to the LEAF (Linking Environment & Farming) guidelines and only cut hedges every two years to then find that neighbours cut everything to the bare soil. John Pinel advised that there is legislation in place to prevent the removal of hedges and he offered support to the farmers in generating positive discussions with landowners regarding best working practices.

One of the issues mentioned at an earlier discussion was that machine operators often suffer abuse from motorists when holding up the traffic and also from home owners if the operators go out early in the morning to avoid the motorists. We sought advice from the Connétables who were present at the meeting and Len Norman advised that the Connétables were willing to close the roads to enable the branchage to be undertaken safely. It’s not easy operating machinery, trying to check where the flail is along the banque and at the same time looking out for motorists, pedestrians and cyclists so, if the level of stress can be reduced, that can only be a good thing.

I was delighted with the outcome of the meeting and, having been involved in this campaign, I have a much deeper understanding and respect for the work that our farmers do.

We have produced two sets of guidelines – a condensed version (which could be kept in the cab of a vehicle to refer to – download this version here) and the more comprehensive version which is still to be formalised by the Natural Environment Department with photos and diagrams (download the draft of this here). Polish and Portuguese versions of the condensed report are available – please check relevant websites or contact Birds On The Edge.

The intention is to distribute these guidelines to private contractors and have them available on Parish and Government of Jersey websites for Island wide use.

A brambling winter at the bird crops

Romano2By Cris Sellarés

To some of us, nothing signals the arrival of the colder months as much as the bloom of the sunflowers from the BOTE winter bird crops across the Island. Their bold colours are the sign that the fields will again produce a good amount of seeds right at the time of the year when our farmland birds need them the most.

Just as the blooming of the crops signals the goodness to come, other signs go up, the ones that we put at the edges of the fields to inform neighbours and visitors about the  role of the fields and their importance to the birds.


Away from their breeding grounds, be they here in Jersey or in far corners of Europe, once the birds arrive at the crops that we’ve prepared for them, all they have to do is survive. This translates in wildlife terms to “eat and do not be eaten”, and this is why the crops play such a crucial role: the seed from the crops provides the food, the structure of the crops and nearby hedges provides cover – from predators and bad weather.

All the birds need at this point is to be left to it, so whilst more and more people love the sight of these impressive flocks by the crops, we ask everybody to enjoy the view from the boundaries and footpaths, and not scare the birds away from their food and shelter.

This winter, with over 60 fields planted at fourteen sites across the Island, is already turning out to be one of the most interesting years that we’ve had at Birds On The Edge.

In late October, when birds started to flock to the crops our resident chaffinches, greenfinches, goldfinches and linnets were joined not only by their continental relatives arriving from the north and the east, but also by other species of finches which we do not usually see in Jersey, in particular dozens, maybe hundreds of bramblings. In comparison, the previous winter only two representatives of this colourful finch were seen at the crops.

Bramblings will hang out with chaffinches and other finches, and have no problem following them to people’s gardens to feed, so if you start seeing chaffinches in your garden, particularly if the weather turns very cold, keep your eyes peeled for bramblings, they will be making their way there soon.


In conclusion, seeing that these hungry bramblings that found their way to Jersey and to the crops are feeding in them is a great sign that the fields are doing their job – providing sustenance for birds in need is exactly what they were planted for.

The seed for the crops was bought with a generous donation from Action For Wildlife Jersey and a grant from the Countryside Enhancement Scheme. Action For Wildlife Jersey is a local group of nature enthusiasts and experts on various fields (excuse the pun) who organise many educational walks and talks throughout the year. The many farmers, sponsors and everyone at BOTE hope that you are enjoying the winter bird crops as much as the birds already are.

Plémont – how to create species rich grassland…. or heathland

Plemont headlandBy Jon Parkes 

July 2016 saw the official opening of Plémont Headland and for the first time in over 140 years (before the original “Plémont Hotel” was built in 1874) the public have been free to enjoy this special place.

Creating and protecting “green space” for people has been at the heart of the Plémont debate and acquisition and indeed forms a very important part of the National Trust for Jersey’s ethos. But ensuring that nature has a home is also a vital component of what we do and there has never been a time when action has been so desperately needed.

In 2015 The States Department of the Environment published the results of the Jersey Butterfly Monitoring Scheme after 10 years of collecting data across 38 sites by a team of dedicated volunteers. The results suggest that whilst Jersey’s butterflies might be faring slightly better to those in the UK, the surveyed population has still decreased by 14%, (compared to 29% in the UK). Interestingly Jersey’s butterfly population is doing best in semi-natural sites as opposed to those in agricultural or urban habitats where they are declining. In fact the green hairstreak is one species that is doing particularly well and has been recorded as increasing by 458% in the last 10 years as opposed to suffering a 40% decrease in the UK. This could be seen as a strong indication of the importance of managed semi-natural sites such as Plémont.


The creation of two ponds at Plémont was eagerly anticipated by the local toad and palmate newt population, who were literally queuing up to jump in upon their completion. For two consecutive years the Eastern Pond has been used by both species to breed. This year, the larger Western Pond has seen a whole new generation of toadlets emerge after metamorphosing from their tadpole stage.

Despite the amphibian successes, both ponds have experienced teething problems and most noticeably the appearance of the lime-green algal blooms. Spirogyra is a family of around 400 species of filamentous algae that is commonly found in freshwater and is indicative of clean water that has high concentrations of phosphates and nitrates. It can be easily removed but doing so would jeopardise any invertebrate life or tadpoles that would become encapsulated amongst the tiny strands of algae.

Plemont pond

Another issue the ponds face is loss of water through evaporation, due to their exposed position to the sun, wind and transpiration – the evaporation of water from plant leaves. Whilst there is means to top up the water levels from a well, this would mean the introduction of more nutrients which would cause more algae. The proposed solution is to encourage more oxygenating plants and remove the algae once the toads have emerged from the water, decreasing the level of nutrients over time. Equilibrium will be reached, the water quality will improve and we will have to accept that the water levels will drop in the summer months. As long as there is water during the amphibians’ breeding period (February-June) the pond is serving its purpose and will act much like many natural ponds without constant water inflow.

Reseda luteola Weld R


Back in the spring of 2015 you may remember the huge mounds of sandy soil which were spread over the footprint of the demolished buildings. Over 7,000 tonnes of sandy soil, sourced from Les Quennevais and recycled soil from La Collette formed the base of what we now refer to as the restoration area. To create a heathland such as Les Landes we would need a free draining sandy soil with a low pH (pH 5-6 ideally) and low nutrient levels. It is easier to maintain a species-rich wild flower habitat when there are fewer nutrients in the soil. If you add fertiliser (or compost or a lot of manure) to the soil, a small number of competitive plants are able to rapidly exploit these extra nutrients. These species then tend to become dominant and other plants are less able to compete for space. Most plants rely on a relationship with fungi and soil micro-organisms in order to grow. Fertilisers have a negative impact on these organisms making it more difficult for the flowers to grow.  With very little choice available, in the quantities we would need, a mixture of sandy soil, sourced from Les Quennevais and recycled sand from La Collette was chosen. Although the average pH was around 8.5, the particularly low nutrient status would mean far less of a burden when it would come to managing the developing vegetation.

This June our Conservation Officer, Jon Rault, assisted by the very knowledgeable local botanist Anne Haden, undertook a vegetation survey to assess how things have developed and have some interesting results. Around 50 plant species have so far been recorded including: wild carrot, toad rush, birds-foot-trefoil and small-flowered catchfly. Maritime Duneland plants such as fragrant evening-primrose, sea beet and sea radish have appeared, but this isn’t so surprising considering the origins of the soil, Les Quennevais of course being built on Dunes. Some more invasive plants such as the non-native cape cudweed and spotted medick which may need some management have become quite well established and some more exotic species including echium and Californian poppy have appeared as likely remnants of the holiday camp era.

Lotus corniculatis Common Bird's-foot-trefoil

Oneothera sricta. Fragrant Evening Primrose.Resent soil tests have confirmed that pH levels are still rather alkaline at between pH 8.5 and 8.9 and this is unlikely to change without any intervention due to the amount of concrete based material that must be underneath the layer of imported calcareous sand. Perhaps more encouraging is the nutrient status results from the same soil samples. For example, the amount of available phosphorus is currently between 8.8 and 25.8 mg/l with a “P index” of 0-3, compared to a recently tested former agricultural field which showed levels of available phosphorus at between 66.2 and 153.4mg/l giving a “P index” of between 4 and 7.

Beta vulgaris subsp maritima Sea Beet.Our current situation, with the encouraging results of vegetation surveys, indicates that the soil choice was a good one. Whilst our soil pH is much higher than we would have ideally liked, this is something that can be changed by adding sulphur, an expensive but affective way of raising acidity. As the results from the former agricultural field’s shows, high soil fertility is much more of a problem with no “magic cure”.

The decision on whether to try to acidify our soil in the effort to meet our original vision of creating a heathland is not one that needs to be made straight away and whilst wildlife and people are clearly making good use of the site, we have already achieved much of what we wanted to do.

For the meanwhile, the addition of calcareous grassland to our north coast may be something of an oddity but this may also be its strength and reason to remain as such. A new and interesting patch adding heterogeneity to the landscape is something that’s often lacking.

Further decisions will be required but there will be a need to balance and create opportunities for nature as well as public access and enjoyment.

Grazing returns to L’Ancresse Common

From La Société Conservation Herd


The (Guernsey) Conservation Herd have been invited to graze L’Ancresse Common and were moved to the common on Sunday 2nd April.

La Société Conservation Herd were invited to graze the Common by Vale Commons Council as a trial to re-introduce grazing. This initiative has been set up under its new management regime which aims to protect the area as an important recreational and cultural site whilst also enhancing the internationally important grasslands.

L’Ancresse Common was historically grazed by inhabitants of Braye du Valle, who have rights to graze their animals there. As fewer households kept their own cows and it became less economically viable for dairy farms to graze theirs on the common, the number of grazing animals there reduced. Today, no inhabitants exercise their right to graze.

This loss of grazing has had a significant impact on the ecology of the common – the grassland has become tall and rank and areas have become established by gorse and brambles. The delicate wildflowers which require short, grazed grassland no longer have access to light and so are being lost from the common. This, in turn, leads to a loss of the insects, small mammals, bats and birds which rely on them.

La Société Conservation Herd

The Conservation Herd is a herd of eight Guernsey steers whose job is to manage grasslands to protect and enhance their diversity. La Société was approached by VCC to graze the common for several weeks, starting from April 2nd. This initiative is a trial of a longer-termed project which aims to see more grazing animals return to the common.

Julia Henney, the Conservation Herd’s manager, said, “We were delighted to be approached by VCC and asked to graze L’Ancresse Common. It is a vitally important site for Guernsey’s biodiversity and we hope that re-introducing grazing will help preserve it for many years to come. We have experience grazing common land, with the introduction of Operation Skylark at Port Soif Common. The local community offered so much support and the herd were well received and accepted onto Port Soif Common and we hope to replicate this success at L’Ancresse.”

The Conservation Herd on L'Ancresse Common. Photo by Chris SimsPeter Blake, President of the Vales Commons Council  said “Myself and my committee wish you and the herd a great stay on the Common and hope that this will encourage more of the inhabitants to do the same.”

The Conservation Herd will be grazing within electric fencing for several weeks around The Doyle area and will be checked daily by the team which cares for them. La Société and the Vale Commons Council would welcome assistance from regular dog walkers and people who walk or exercise around L’Ancresse. ‘Watchers’ are sought to keep an eye on the cattle when they’re passing and report any problems or concerns to the Conservation Herd team.

Temporary signs are placed around the site to explain the project and give information on who to contact in the event of an emergency.

Anyone who would like more information on the Conservation Herd is welcome to contact Julia Henney at and visit our online map here to track where they are grazing.

Winter bird crops feeding more threatened birds every year

photo-by-romano-da-costa-1By Cris Sellarés

The Winter Bird Crops are going from strength to strength looking at the way the birds are rushing to get to them. Results from last winter’s surveys at the crops show an increase in bird numbers of almost 40% in density (birds per hectare), even when the number of fields and area planted did not increase from the previous year. Most encouragingly, the vast majority of birds feeding at the crops were the targeted species: farmland birds such as chaffinch, linnet, reed bunting, meadow pipit, goldfinch and starling.

The winter bird crops are crucial to keep hundreds of birds fed and alive throughout the winter, when there is not much food to be found in the fields or hedges. Many of the species benefiting from them are threatened right across their British and European ranges, and include local birds and migrants who come to spend winter here.


You can download and read the full report 2015-16 Winter bird crops report here. Here are the highlights:

  • photo-by-romano-da-costa-4Farmland birds are in decline across Europe, the UK and Jersey, with some species having become locally extinct and many others considered threatened. One of main reasons of these declines is lack of food during winter which causes high levels of mortality. The so-called ‘Winter Bird Crops’ provide a source of food at this critical time, increasing the chances of survival of many threatened birds both local and migrants
  • Birds On The Edge works with Jersey’s potato farmers to provide winter bird crops for the longest time possible. A variety of crops are planted with staggered management regimes, ensuring that the crops do not disappear at once when the fields are planted with potatoes. The crops provide seeds and grains of various sizes, energy and nutritional values
  • In 2015 a total of 47 fields were planted to feed farmland birds during the 2015-16 winter. The fields were found at 12 different sites, and, combined, covered a total of 33.3 hectares (163 vergées)
  • The development of the crops and bird activity was monitored throughout the winter. A total of 46,155 records of birds of 54 species were collected over sixteen surveys, of which 40,949 (88.7%) were of target species (endangered farmland birds)
  • Of the ten most abundant species found at the crops, seven were farmland (target) species: chaffinch, linnet, starling, goldfinch, greenfinch, meadow pipit and reed bunting. A total of 14 target species was recorded at the sites. The most successful site had an average of 461 target birds per hectare
  • Net numbers increased by 13,874 birds compared to 2014-15 (54% increase) and by 33,177 compared to 2013-14 (534% increase)
  • The overall density of target birds increased by 39% from the previous winter (2014-15) and by 140% compared to the winter of 2013-14
  • The seed for the bird crops was purchased and provided thanks to the generosity of a private donor. It costs approximately £3,500 to plant the winter bird crops in Jersey
  • This year’s crops, which are already feeding birds in larger numbers than ever recorded, were paid for by the local charity Action For Wildlife and by the States of Jersey’s Countryside Enhancement Scheme
  • Our research proves just invaluable the crops are for these vulnerable species and we believe that continuing this scheme is paramount for their survival. As we begin to plan for next year’s crops with the farmers, Action For Wildlife has stepped up once again and donated £1000 towards the seed for next year’s crops. This will be added to a private donation of £200 we received in the autumn, as we close in our target of £3,500.

New hedge planted near St Ouen’s Pond to help birds

Reed bunting male. Photo by Romano da Costa.By Cris Sellarés

JTFLA recent collaboration between Jersey Trees for Life and Birds On The Edge has seen a new hedge planted at an important conservation site in St Ouen’s Bay.

The new hedge, approximately 200m long, was planted at the edge of the National Trust for Jersey land and the Site of Special Interest of St Ouen’s Pond (SSI La Mare au Seigneur). The boundary lies between the Trust’s grazed pastures east of the reedbeds, and privately farmed fields west of the Rue du Val de la Mare. The potential value of creating a hedge in this area was identified during recent habitat and wildlife surveys carried out by BOTE, as part of a larger group of actions to enhance opportunities for wild birds in the area which were recommended as a result of the surveys. Other actions that were suggested included the planting of winter bird crops and setting up farmland feeding stations.


A few months ago the local charity Jersey Trees for Life got in contact with BOTE to find a location for a new hedge project in St Ouen’s Bay, for which they already had possible sponsors, and this location was suggested. After obtaining permissions from NTJ and other landowners, the staff of JTFL proceeded to plant a total of 606 hedging whips. The bulk of the plants was comprised mainly of hawthorn, with some blackthorn, wild plum, grey sallow and a few shrubby aspen in as well. They were planted in double and triple rows over on the top of the wide existing bank, and the hedge was completed by mid-March.

DSC_0166It is hoped that the particular placement of this hedge will connect various habitats of importance to birds, especially the reedbeds near the pond that extend to one side of the grazed area, and the arable fields on the other side of it, which most crucially are planted every year with Winter Bird Crops. Many birds have been found in these crops during winter surveys, in particular the locally extinct (as a breeding bird) reed bunting, which now only winters in Jersey with a population of Reed bunting. Photo by Mick Dryden200-400 birds, mainly in St Ouen’s Bay. These buntings roost at night in the reedbeds and travel across the Island during the day to feed on small seeds from weeds, crops and marginal vegetation at small and spread-out sites. They do not like to feed on open ground like linnets nor are tame enough to visit garden feeders, but they have found a great source of food in the Winter Bird Crops managed by BOTE, especially the ones near the pond. However, to get to these fields from the safety of the reeds they still have to cross a large expanse of open ground, namely grassland and pastures. It is hoped that this hedge will provide them with a safety corridor to use not only for travelling between the roosting and feeding areas but also with shelter from predators and adverse weather, allowing them to remain in the feeding area for longer periods at a time.

Many other birds can potentially benefit from this hedge, as it can also provide nesting habitat and a varied source of food (in the form of buds, berries and insects). Greenfinches, chaffinches, linnets, stonechats, Dartford warblers, starlings and many more are likely to benefit from this hedge and the other habitats and features that the hedge will make accessible to them. Other wildlife that will probably use it too includes green lizards, grass snakes, rodents and shrews, toads, numerous insects and other invertebrates.

The future looks good for this area, as there is already an agreement with the local farmers to plant more Winter Bird Crops in 2016 for next winter, and further good news also from Jersey Trees for Life, as they plan to extend the hedge next winter following the same boundary southwards. From our side at Bird On The Edge, we will continue to monitor the birds using the crops and the hedge, and we hope that the data collected over the next few years will reflect the improvements on this area promoted by the bird crops and the newly planted hedge, especially as it develops and reaches full maturity.

*This project has been possible thanks to a very positive collaboration between the local farmers, landowners, JTFL and the BOTE partnership.

Sheep attacked in Beauport

Grazing sheep at Le Marionneux. Photo by Liz Corry

By Aaron le Couteur

This is the very real consequence of not being a responsible dog owner. I’d first like to say thank you, thank you to all the good owners out there, who understand their own animal, and respect others, but even if you think this is you, please read on….

To the culprits, I really don’t know what to say. You may think that this is just a sheep, but I’d say you’re wrong. Her name is Bercail Gallant, she was born on the 7th March last year at quarter to two in the afternoon and weighed just 2.9kg. You could hold her in the palm of one hand. I did, I was there. This is a living, breathing creature that gets scared like we do, that has instincts like we do, that feels pain like we do, and that deserves compassion and respect in equal measure to your pet. No animal ever deserves to go through this, and what makes it so difficult to swallow is that there is absolutely no need for it.

It would be easier to sleep at night to think this dog owner was an awful malicious person, with a menacing dog. The difficult reality is that all too often these attacks are caused by well-meaning people, who never for a second think their dog would have this in them, but they do. They all do. So, if the video (on Facebook) upsets you, please, please be responsible. Train your dog to have a solid recall, never let them out of your sight, and if you can’t control your dog, use a lead. But if something like this does happen, let the owner know, don’t ever leave the animal suffering. PLEASE.

Bercail Gallant. Photo from The Reserve

This happened on Tuesday morning last week in the early hours, sometime before 0800, in the Beauport area. Five sheep in total had various wounds and injuries. Thanks to some outstanding veterinary work, Gallant has a shot of pulling through, it will be a long road, which she doesn’t deserve, but we will give her every chance.

Please don’t forget, these sheep are members of the Birds On The Edge team like us and like the choughs and deserve every bit as much respect as we all do.

Sheep and lichens at Sorel

Cladonia fimbriata RBy Anne Haden

How do lichens and sheep get on together? Lichens are a great indicator of the quality of the air around us. Lichens like to grow where the air is pollution free, hence the profusion of lichens around the Jersey coast. They are formed from a fungus living in mutual association with an algae and are able to live on different surfaces like soil, wood or rock.

Ramalinas and crustose lichens on rock RThe short turf at Sorel has been opened up by the sheep and the habitat allows a range of lichens to grow between the grasses. Common lichens to be seen on the soil up here include Cladonia furcata and Cladonia fimbriata. Cladonias sometimes have friuting bodies that are cupshaped and easily identifiable in the field.

Open heaths provide an excellent habitat for some of the more unusual Cladonias, the heathers are being encouraged to return to Sorel to create more heathland. The National Trust has fenced off some heathers to encourage them to self seed.

Ramalina siliquosa Sea Ivory RLichens growing on rock can be seen near the cliffs at Sorel, including the very common sea ivory Ramalina siliquosa. There are several varieties of Ramalina on the rocks, careful study reveals some strands are flatter and some bear fruiting bodies. Also on the rocks are flat patches of crustose lichens that are firmly embedded on the rock and are very slow growing.

Xanthoria parietina RThere are not many trees at Sorel; however, the blackthorn and hawthorn bushes provide branches and twigs that are covered in lichens. Especially the very common Xanthoria parietina that gives rise to the expression ‘yellow trees’. Close examination of Xanthoria parietina shows lots of round fruiting bodies often called ‘jam tarts’ by lichenologists. This lichen grows well in nitrogen rich air, hence the increase in Jersey due to the rise in nitrogen in the air from farming activities. So, yes, lichens, like choughs, do appreciate those sheep making it a better place for them at Sorel.

Coastal grazing project – coastal slope between Grosnez and Plémont


By Tim Liddiard

The rugged north coast of Jersey is one of the Island’s most stunning and dramatic locations. It provides a strong sense of place, supports a unique and internationally significant assemblage of plants and animals and is a honeypot for recreation for locals and visitors alike.

These unique qualities have led to the area being designated as a National Park within the Island Plan – the first such designation in the Channel Islands – and being perceived by the majority of stakeholders, as one of the most ‘special’ parts of the Island.

The north coast forms an almost continuous belt of natural wild landscape from St Catherine’s in the east to Les Landes in the west and contains an intricate network of protected areas supporting a wide variety of wildlife.

Despite its beauty and importance, a wide range of indicators, including those within the Government’s own ‘State of Jersey Report’ show that the north coast is an area suffering ecological decline, particularly in relation to populations of key bird species. It is clear that further management is required to return these areas to favourable condition as required by the Island’s domestic and international commitments.

International and domestic obligations

Manx loaghtan sheep at Le Don Paton. Photo by Aaron le Couteur (17)The coastal slope between Grosnez and Plémont is an Atlantic Dry (Maritime) Heathland described as in an ecologically unfavourable condition and the majority is designated as a Site of Special Ecological Interest under the Planning and Building (Jersey) Law 2002.

Maritime heathland has a very limited global distribution being restricted to the north Atlantic coasts of Europe, where it once occurred widely, but has now been reduced in area to such an extent that it has become a rare habitat in Europe.

The habitat is listed for special attention under Annex 1 of the EC Habitats Directive. This Directive was adopted in 1992 as an EU response to the Bern Convention on the Conservation of European Wildlife and Natural Habitats, to which the States of Jersey are signatory. This allows Jersey to demonstrate that the Island is a responsible jurisdiction in terms of environmental protection and the maintenance and enhancement of the Island’s globally significant and unique assemblages of plants and animals. These types of habitats require careful management for them to retain the features that make them ecologically valuable.

The purpose and objectives of reintroducing grazing

Up until the beginning of the 20th Century the coastal headlands and north facing escarpments were an important part of the rural economy in Jersey. Cattle, ponies and sheep would have grazed upon these areas and gorse and bracken would have been collected for fuel and bedding respectively. Today such practices no longer take place and bracken and scrub has encroached, leading to a decline in biodiversity and resulting in many coastal and heathland species becoming extinct locally, with others in dramatic decline such as the skylark, yellowhammer and stonechat (see details of declines here).

Manx loaghtan sheep at Le Don Paton. Photo by Aaron le Couteur (18)Consequently, in Jersey such areas need to be actively/physically managed to prevent the sites generally and the heather specifically from moving into what is described as the degenerative stage and to prevent encroachment of bracken, which swamps other plants as is very difficult to remove once established.

Sites in Jersey are managed through a long-term partnership between Department of the Environment, the National Trust for Jersey as part of their Coastline Campaign and Durrell. The partnership also supports Birds On The Edge Project promoting the active management of Jersey’s coastland to maintain and restore populations of birds.

One of the BOTE’s critical objectives is to re-establish grazing flocks to achieve sustainable and cost effective land management which will enhance the heathland landscape and habitats on Jersey’s cliff tops.

Key objectives are not restricted to ecological outcomes and include:

In 2008, the National Trust for Jersey introduced 20 Manx loaghtan sheep into an area of 180 vergees between Sorel Point and Devil’s Hole to undertake conservation grazing in the Island. The sheep flock is being built to a sustainable size over the next few years by extending the areas that are grazed to prevent over-grazing, whilst allowing the flock to grow into an economically viable business. This is an exciting long term project which is at the forefront of the Island’s countryside conservation work.

Proposed extension to grazing area

The area between Grosnez and Plémont has been the subject of a planning application to erect livestock fencing which has generated both supportive and unsupportive comments from locals.NE-IM-GRosnez fence (1)

Issues raised included the cost of the project and that fishermen and others will not be able to access the site; however, gates would be positioned to allow easy access and egress for all users to and from the grazed area at most times of the year. The provision of a north coast route extension will cater for those not wanting to place dogs on leashes.

The question has also been raised about the stocking density and timing of grazing. There is great scope for flexibility here – there will be options to mob graze (large numbers of animals for very short periods) or more gradual grazing with a low stocking density, although this is to some extent dependant on the grazier’s requirements. The effects of grazing will be monitored to ensure that no damage is caused to the rich archaeology which exists here and to habitats by overgrazing.

Management costs

The total area selected for grazing measures is 124 vergees of which 50% is bracken scrub. The costs of management fall into two categories a) the relatively flat areas managed by tractor and by hand (50 vergees) and b) the coastal slopes, inaccessible by machine and managed by hand (74 vergees).

Mechanical and chemical control and management by hand will cost approximately £24,705 per annum.

Control by grazing animals will cost approximately £8,550 per annum with a one-off capital cost of £17,000 for fencing including materials and labour.


  • The Island has domestic and international obligations to protect its non-renewable natural resources
  • Strong evidence suggests that protected areas on the north coast of the Island are in ecological decline and that management is required to reverse these declines and avoid future extinctions and habitat degradation
  • Any management regime should be cost effective, particularly at a time of austerity, sustainable in the long-term and where possible provide multiple benefits to the Island
  • The use of grazing animals is a third of the price of mechanical intervention and provides a range of added societal benefits and consequently appears to be the most cost effective and appropriate option for ongoing heathland site-restoration on the north coast
  • If the lands were left to overgrow there would be significant knock-ons to public access to the countryside in addition to substantial costs to re­ establish pathways and routes should this be deemed necessary.

How are the birds doing on Jersey’s north coast?

DSC_0045The latest Annual Bulletin of the Société Jersiaise includes a paper on the current status of the birds of Jersey’s north coast with details of trends in their populations over 30 years, 1985-2014.

The north coast of Jersey is one of the most important areas for birds on the Island and will be included in the Jersey Coastal National Park. The cliffs have traditionally held large numbers of breeding seabirds including iconic species like the Atlantic puffin and raptors like the peregrine. A wide variety of vegetation types on the upper slopes of the cliffs and marginal, mixed farmland on the cliff tops have been strongholds for many songbirds including stonechat, meadow pipit and linnet, birds typical of Jersey’s coastline and now found only rarely elsewhere on the Island. Jersey’s now extinct yellowhammer population was previously restricted to the north coast.

In recent years, however, changes in agricultural practices locally, notably the abandonment of many marginal cliff-top fields and encroachment by bracken, threats of widespread development and increase in leisure activities have led to growing concern for the Island’s coastline. Long-term monitoring of the bird populations is a powerful tool, showing in part what is happening to Jersey’s wildlife at the start of the 21st Century.


Survey methods

Jersey’s north coast cliff path runs from L’Étacq to Rozel. The majority of the path (typically from L’Étacq to Les Platons) was walked west to east on one day each year (typically during June) by Glyn Young and others. All birds of every species except herring and lesser black-backed gulls seen or heard at any distance either side of the path were recorded. The two gull species were not counted because, nesting on the cliffs, they are present at all times and difficult to count with this method. These gulls are, however, included in other Island-wide surveys.

There are many variables inherent in this methodology (date, weather on the day, onset or delay in spring etc. and even exact finishing point); however, the spread of 30 years data will exhibit robust trends in populations despite this.


A total of 87 bird species were recorded. While the number of species seen each year stays similar (at around 50 each year), the overall number of individual birds seen each year shows an alarming downward trend.

Gains and losses

The fluidity of the north coast’s bird fauna can be seen by changes in the species composition since 1985. Species recorded in at least 10 consecutive years from 1985 and not seen for more than five years until 2014 can be considered lost. Species that were first recorded since 1985 and seen in more than five consecutive years up to 2014 are considered gains.

Photo by Mick DrydenThe species gained (three diurnal raptors and a corvid) are typically those that have been persecuted, if not in Jersey, certainly elsewhere, and that have seen increases in continental and UK populations following statutory protection. In contrast the losses (three songbirds and a dove) are species likely to have declined through a more varied and often unclear combination of causes within and outside of Jersey including widespread habitat modification and loss, especially in farmland and marginal land, and global climate change. This is of concern as whereas simply protection may have helped restore populations of some, often high profile, species, we are seeing serious declines of formerly common species despite ongoing protection.

Jersey has nine breeding seabird species, of which seven nest on the north coast. Of these, six are threatened with extinction locally (see our Red List here). The north coast population of shag was described as very stable in 1996. It has proved quite the opposite since then with the causes of this decline not yet determined. In contrast, perhaps, the situation with Atlantic puffin was more expected with a longer history of decline. The razorbill, in contrast, remains scarce but may be relatively stable with less than 10 pairs. The great black-backed gull population fluctuates annually but is stable or increasing slightly while the colonisation by fulmar (it first nested in Jersey in 1974) appears to have ended: the 75-100 pairs reported in 1996 have not increased or spread from the north coast.

Diurnal raptors

Numbers of diurnal raptors (here two unrelated groups, hawks and falcons) recorded on the north coast have increased dramatically since 1985. Only kestrel was recorded in 1985 with occasional sparrowhawk (now resident) and migratory hobby adding to the figures in the next few years. Peregrine was first recorded in 1994 but has been seen annually since it returned to Jersey to breed in 2000 after an absence of 42 years. Marsh harrier and common buzzard were first recorded in 2006 and 2012 respectively four and five years after each species was first recorded nesting in Jersey. The kestrel is the only raptor to have been recorded in every year of the survey and, while numbers recorded each year have fluctuated (from five to 22), the population appears fairly stable.

Pigeons and dove

Pigeons and doves (columbids)recorded on the north coast, have shown varied fortunes over the period of study. While only the feral population of rock dove (there are both naturalised, breeding, birds and those possibly still involved in a human activity (‘racing pigeons’) present) can be considered truly cliff nesters, the closely related stock dove and wood pigeon were recorded both on the cliffs and in the cliff-top fields. Two smaller species, the doves, turtle dove and collared dove, are birds of farmland, the latter typically in close association with human dwellings.

Rock dove appears to have a stable, although fluctuating, population whereas each of the other species has declined. Wood pigeon and stock dove are very common in other areas of the Island, seeming, in recent years, to simply shun the cliffs. Stock dove was considered (in 1996) to nest widely on the cliffs but now does so only rarely. While the decline of the turtle dove throughout Western Europe is mirrored in Jersey (it may now no longer breed on the Island) the decline of collared dove is more interesting. Collared doves are common in urban and sub-urban areas but increasingly scarce in farmland where the return of the predatory sparrowhawk and peregrine may have influenced their habitat choice. Similarly, the reduction in stock dove on the cliffs may have followed the return of the columbid-feeding peregrine, the doves choosing to nest inland in safer sites.

Meadow pipit and linnet are birds of the coast in Jersey, preferring too relatively undisturbed areas. These two species probably now breed predominantly on the north coast. Although the decline of the linnet is dramatic, the much reduced population does at least appear to have stabilised since 2005. Jersey’s breeding population of meadow pipit is not high but it too does appear fairly stable on the north coast. The stonechat is another species in steep decline locally with no more than five pairs breeding some years. It is likely that the north coast holds the majority of breeding pairs although even here the population fluctuates.

Two further species, starling and house sparrow are worthy of note. These two birds, formerly considered abundant in Jersey, have declined alarmingly on the north coast. Although both these species are often associated with human dwellings, at least when nesting, it is perhaps a sign of the state of the former farmland on the north coast that both species are doing so badly here.

It is very clear even from this single annual survey that the bird populations on Jersey’s north coast are not faring well. It is clear too that some species and some groups of species are faring particularly badly while some others are apparently stable or even increasing. Although the causes of the declines are not clear and complex, the rise of raptor numbers shows the benefit of widescale, targeted, species-based conservation initiatives while the decline of seabirds and those species dependent on farmland and marginal land shows larger, possibly even global, concerns that will be much harder to redress. Birds On The Edge aims to restore Jersey’s declining coastland birds and return those species now locally extinct.

I am very grateful to Roger Long and the Société Jersiaise for allowing use of the graphs in this piece.
