Plastic found lining UK seabird nests on a worrying scale

From The Conversation

From the packaging our food comes in to the clothes we wear, plastic is everywhere. We know that seabirds eat it and get tangled in it, but we are only just beginning to explore the impacts this has on their health and survival. This is really important, particularly in the UK and Channel Islands where many species, such as the northern gannet and Manx shearwater, breed in greater numbers than anywhere else in the world.

Many seabird species are in drastic decline. A recent report found that in the last 18 years, the UK population of European shags has fallen by 24%, kittiwakes have reduced by half and Arctic skua populations have shrunk by 70%.

But what is behind these declines remains something of a mystery. Overfishing and climate change are thought to be key drivers, but despite knowing that plastic is widespread in their environment, we currently lack even the most basic data on which seabird species are affected by this pollution and how.

Before we can effectively deal with any threat posed by plastic pollution, we need to understand the scale and type of effects it’s having. A new study is a first step towards this, uncovering evidence that Scottish seabirds are not only ingesting plastic, but they appear to be accumulating it in their nests.

Unpicking the impact of plastic

The study looked at five European seabird species – cormorants, European shags, great black-backed gulls, herring and lesser black-backed gulls. The latter four of these are of “Conservation Concern” in the UK according to the RSPB, while cormorant, shag and herring gull are included in Jersey’s ‘red list’ due to their declining or vulnerable populations.

Plastic pollution was intimately intertwined with the nesting behaviour and daily lives of these species, possibly affecting their breeding success and survival. 32% of herring gull nests, 53% of great black-backed gull nests and, worryingly, 80% of European shag nests contained plastic. Even worse, 39% of herring gull pellets – regurgitated bits of indigestible food – also contained plastic.

Plastic in nests is known to ensnare adults and chicks, often with fatal consequences. For some species, the nest must keep the egg warm and dry. It’s not clear whether plastic could be altering how well the nest warms its occupants or allows liquids to drain, but any changes could affect hatching success. Equally, the range of colours plastic comes in may affect the nest’s camouflage, making eggs and chicks more vulnerable to predators.

The study found clear differences in the type of plastic in herring gull nests from that contained in their pellets. This may reflect differences in where this species collects its food and its nest material. The ingested plastic was a variety of colours and types, including fibres, packaging and hard fragments, suggesting it might be found in an urban environment or in a landfill. But the nest plastic found was only sheet packaging, the sort more likely to wash up on the shore closer to their home.

This kind of information can help us begin to understand how effective different efforts might be. If the plastic used for making nests is collected from the shore before nest building begins in early spring, like during beach cleans, it could limit the impact on particular seabird species.

As nationwide lockdowns have eased during the COVID-19 pandemic, unprecedented levels of plastic waste have been left on UK beaches. We’re only just peeling back the surface on how this pollution harms wildlife. But as the evidence mounts, the urgent need to prevent plastic entering the environment becomes ever clearer.

Most wild bee and native plant species networks lost over last 100 years

From EurekAlert

Climate change and an increase in disturbed bee habitats from expanding agriculture and development in north-eastern North America over the last 30 years are likely responsible for a 94% loss of plant-pollinator networks a new study has found. Despite this study being from North America it is hard to imagine that Jersey has fared very differently.

The researchers looked at plant-pollinator networks from 125 years ago through to the present day. The networks are comprised of wild bees and the native plants they historically rely on, although most of those have now been disrupted.

About 30% of plant-pollinator networks were completely lost, which translates to a disappearance of either the bees, the plants or both. In another 64% of the network loss, the wild bees, such as sweat or miner bees, or native plants, such as sumac and willow, are still present in the eco-system, but the bees no longer visit those plants. The association is gone.

The remaining 6% of the plant-pollinator networks are stable or even thriving with pollinators such as small carpenter bees, which like broken stems for nest making.

“There are several reasons for the losses in the networks. Climate change is likely the biggest driver. We know that over the last 100 years or so annual temperatures have changed by two and a half degrees. This is enough to alter the time when certain native plants bloom,” says author Professor Sandra Rehan.

“For a bee that’s out for months on end or is a generalist pollinator, this isn’t such a critical mismatch, but for a bee that’s only out for two weeks of the year and only has a few floral hosts, this could be devastating.” An increase in non-native species of bees and invasive species of plants, which have displaced some of the native species, is another reason for the decline in networks. “We are getting a lot of invasive species and new records of invasive species every year. This is usually accidentally through trade and through ornamental plants,” says Rehan.

A lot of these bees live in stems, so it’s easy to import plants with non-native bee species without knowing it. “We can actually show routes and means of invasion biology,” she says.

These bees are following shipping routes from one continent to the other around the world, including North America through ornamental plants for our gardens.

The researchers say an increase in habitat restoration and native flowering plants in agricultural landscapes are critical for improving wild bee biodiversity, but also food security for humans.

Bees and other pollinators are worth hundreds of billions of (US) dollars globally by pollinating the crops we eat, and wild bees are at the top of the list believed to pollinate more than 87% or 308,006 flowering plant species. Many of these are economically important commercial crops, such as apples and blueberries.

“There is an urgent need to gain a deeper understanding of the environmental circumstances affecting these wild pollinator populations and their specialised, evolutionary relationships with plant communities,” says Rehan. “Plant pollinator webs are dependent on changes in the landscape, so knowing how these networks are shaped is important for all regional habitats.”

Previous recent research by Rehan and team looked at 119 wild bee species over 125 years and found 14 declining and eight increasing species. All of the wild bee species in decline are native (to North America) and over half experienced significant range (latitude and elevation) shifts.

Restoring farmland ponds attracts more farmland birds

From Rare Bird Alert

Less than 70 years ago, ponds were a common feature of the farmland landscape, and were routinely managed just like hedgerows. Since the 1950s, many ponds have been filled in to reclaim more land for farming; however, a large number have been left unmanaged, meaning they have become overgrown with trees and bushes, making them dark and uninhabitable to many species.

Wildfowl & Wetlands Trust has been working with the Natural History Museum and University College London on research that shows reinstating traditional pond management methods, of tree and mud removal, can benefit not only pond species, but also farmland birds.

Ponds restored by the Norfolk Ponds Project, were compared to neighbouring unmanaged and overgrown ponds; restored ponds contained twice as many bird species and almost three times as many birds, as the overgrown ponds.

Bird species at the restored ponds included skylark, linnet, yellowhammer and starling, all species that are Red Listed in the UK because they have declined drastically in recent years.

There were 95 sightings of these four species in and around the restored ponds, which compared to just two sightings of yellowhammer and none of skylark, starling or linnet at the unrestored ponds.

The total number of birds visiting was also greater at restored ponds with almost three times as many birds attracted to the restored ponds. This was shown to be linked to the abundant insect food resources emerging from restored ponds.

According to lead researcher, Jonathan Lewis-Phillips of UCL’s Pond Restoration Research Group:

“Restored ponds are teeming with insects, and because different ponds have insect peaks on different days, birds can move from pond to pond, and get the food that they need. A network of high-quality ponds is, therefore, brilliant for birds in the breeding season.”

With a network of restored ponds across the landscape, birds were able to move between insect emergence events, providing an ongoing insect food resource during the breeding season.

The research comes at a time when farmland birds are under huge threat, having declined by 55 per cent in the last 50 years, largely due to changes in agricultural management to increase food production, according to the recent State of Nature 2019 report.

As well as providing a beneficial habitat for woodland birds, farmland ponds also provide an important landscape feature, and act as stepping-stones for other wildlife including frogs and dragonflies.

Despite their importance, according to a report published by the RSPB, WWF and the Wildlife Trusts, there are no plans to protect them included in the UK’s new Agriculture Bill.

“Our research shows how important it is to restore and manage ponds in farmland. Here in Gloucestershire, preliminary evidence suggests we have lost around two-thirds of our farmland ponds since 1900. That’s why we have been working with Farming & Wildlife Advisory group (FWAG SouthWest) and local farmers to restore a number of ponds across different farms on the Severn Vale.”

“Even following long periods of dormancy, overgrown farmland ponds can quickly come back to life, with plants, amphibians and insects starting to colonise them in a matter of months. That is why this research could be an important pointer of where the UK’s environmental and agricultural policy should focus post Brexit.”

Carl Sayer of University College London Pond Restoration Group said: “The research on birds was inspired by Norfolk farmer Richard Waddingham. His constant belief has always been that farming and wildlife can co-exist and with wildlife declining at an alarming rate, at no time in history do we need to make this work more than now. Restoring farmland ponds is clearly part of a positive way forward.”

Hedge Fund Project 2019/20

The National Trust for Jersey are looking to appoint a volunteer planter to assist in the planting of bare root hedging and tree whips (45-60 cm) on designated field boundaries working eastwards between the Zoo and Rozel Manor/Fliquet.

  • Once planted the whips will be fitted with spiral guards or trees shelters as appropriate
  • The majority of the 5,000 holes to plant the whips have been dug to allow them to be slot planted. Spiral protection has to be fitted to a lot of the hedging that has already been planted and this type of work is less arduous and would suit those who are not so physically strong
  • There is the potential of work in the summer as well, maintaining the planting in order to control competing vegetation.

The appointee will be responsible to Conrad Evans – Project Coordinator or National Trust Supervisor in his absence. The appointee will need to be:

Responsible for 

  • Own transport to site and meeting at designated working site which will vary as progress is made
  • You will need to wear appropriate clothing, gloves and footwear and provide food and drink for your own welfare
  • Looking after the tools, plants and materials that will be provided
  • Complying with the risk assessment that will be given to all volunteers.

Key responsibilities 

  • Working with minimal supervision from time to time taking care of your own health and safety in line with the likely working conditions to be expected
  • Be respectful of the land, environment and any livestock encountered
  • Deal politely with any public interest
  • To have the ability to work as part of a team to a high standard.

Experience required

  • Being physically fit and able is a vital condition of the task
  • Basic gardening, horticulture or labouring
  • Ability to work under own initiative having been given initial instruction.

 Hours 

  • Monday to Friday between 0830 and 1530
  • Minimum of 4 hours per session to ensure efficiency and a reasonable level of production.

Contact and any necessary medical details will be required but ALL information held with be kept in the strictest confidence.

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.

Romano1

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.

Brambling12wm

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.

Ponds

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.

Grassland

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.
