The NHBS Introduction to Habitats: Farmland

Farmland by Tony Armstrong-Sly via Flickr

The next habitat in our NHBS Introduction to Habitats series is farmland. Farmland encompasses a wide variety of different habitats, many of which can be rich in wildlife. Farmland itself is not defined under the UK Biodiversity Action Plan as a habitat, but it contains four habitat types that are identified: arable and horticulture, boundary and linear features, improved grassland and standing open water. These habitats are important for many plant species, as well as a variety of birds, mammals, amphibians and reptiles.

Farming has been a part of the UK landscape for thousands of years and methods are constantly changing as consumer tastes shift and new technological innovations emerge. With an estimated three-quarters of the UK being farmland, it is unsurprising that these habitats are used by so many species. It is also not surprising just how important environmentally friendly farming practices are.

The need to utilise as much of the land as possible to increase productivity has led to a rapid decline of boundary and linear features, such as stone walls and hedgerows. These features constitute a significant ecological part of the farmland habitat, providing variety, food and shelter for wildlife, as well as helping to reduce run-off, flooding and soil erosion. Hedgerows and tree lines can also play an important role in carbon sequestration in agricultural landscapes.

What species can you find here?

Flora

Beyond crop species, farmland can be home to a large number of flora species that can all play key roles in the ecosystem. These plants support the large variety of fauna species found on farmland. The abundance and diversity of plant species depends on the type of habitat and the level of ‘improvement’. Improved grasslands are areas that have been re-seeded and treated with chemicals, such as fertilisers, herbicides and pesticides, and typically species diversity is much lower compared to unimproved or semi-improved grasslands.

Blackthorn (Prunus spinosa)

A common hedgerow species, blackthorn flowers in early spring and produces fruits in autumn and winter, providing an important food source for many species, including invertebrates and birds. It is visually similar to several other species, such as wild plum and wild cherry, but can be distinguished by its fruit size, leaf shape and the time of year that the flowers bloom.

Common Hawthorn (Crataegus monogyna)

Hawthorn is another common hedgerow species, providing food and shelter for species such as yellowhammers (Emberiza citrinella) and the hawthorn moth (Scythropia crataegella). The red berries, called haws, develop during autumn and winter, and are an important source of food during the colder months for many farmland species. Did you know that hawthorn was originally associated with May Day? It was used before the development of the Maypole, with its leaves and flowers used in garlands.

White Clover (Trifolium repens)

This plant is often used as a companion plant for crops, providing additional ground cover to reduce soil erosion. White clover also fixes nitrogen within the soil, allowing for better crop growth. Clover suppresses the growth of unwanted or damaging plants too, and also acts as a trap for pests to draw them away from valuable crop plants. This practice helps to improve farmland for wildlife as it prevents it from becoming a monoculture, adding more variety in food and shelter resources. The use of cover crops within agriculture has reduced, however, and white clover is much less abundant on farmland than it once was.

Creeping Thistle (Cirsium arvense)

The creeping thistle is an important source of food for many farmland birds, such as goldfinches and linnets, but it’s often considered a ‘weed’ and is normally quite heavily managed on agricultural land. Its flower heads consist of lilac-pink florets on a cylinder of spiny leaf-like structures called bracts. During the late summer, it releases fluffy, wind-borne seeds en masse.

Fauna

Many iconic UK species use farmland and the fauna present changes depending on the time of year. Farmland can seem to come alive during spring and summer, although there is still much to see during the colder months.

Grey Partridge (Perdix perdix)

Grey partridge by Ekaterina Chernetsova (Papchinskaya) via Flickr

This species is an iconic part of farmland wildlife, with its orange face, dark black semi-circle patch on its abdomen and stripy grey and orange-brown feathers. The grey partridge relies on the seeds, leaves and certain invertebrate species that it finds in open farmland and has a preference for areas with hedges. It is a ground-nesting bird, laying the most number of eggs per clutch of any bird (the record is 25).

Grey partridge numbers have declined by more than 80% in the UK since the 1980s. This has mostly been attributed to a loss of seed sources, habitat loss and predation, for example by cats and foxes. Luckily there are several conservation efforts in place to help this species.

Yellowhammer (Emberiza citrinella)

These brightly coloured birds prefer open countryside with bushes and hedgerows, and so they are often found in farmland habitats. Yellowhammers feed on invertebrates and seeds, relying on farmland seeds during the winter as snow cover can make it difficult to find food elsewhere.

Heart and Dart Moth (Agrotis exclamationis)

Farmland habitats are home to a great many invertebrate species, with a large variety of butterflies and moths. The heart and dart is an easily identifiable moth due to its distinctive markings. It has a blackish v-shaped collar, with a dark dart mark and two circular marks on its wings. The wing colour can vary from lightish grey to a much darker brown. They feed on a variety of plants such as brambles (Rubus spp.), maize (Zea spp.) and lettuce (Lactuca spp.).

Brown Hare (Lepus europaeus)

While not a true native to the UK, as they were thought to have been introduced during Roman times, this species is now considered naturalised. It prefers a mixture of grassland, arable fields and hedgerows, grazing on vegetation and the bark of young, woody plants. Rabbits (Oryctolagus cuniculus) can also be seen on farmland, although they can be distinguished quite easily as hares are much larger, with longer limbs and longer, black-tipped ears.

Farmland can also support many of the UK’s small mammal species. For more information on those, check out our NHBS Guide to UK Small Mammal Identification.

Threats

Intensification of agricultural practices has led to a reduction in habitat areas that are seen as unproductive, such as hedgerows, rough grassland and open water areas. It has been reported that 60% of farmland species are now in decline. As well as agricultural intensification, other factors behind this decline include changes in farming practices; the use of harmful chemicals, such as insecticides; overgrazing by livestock; destruction of habitats and soil erosion.

Habitat changes caused by development, afforestation or conservation efforts that prioritise alternative habitat types can also pose a threat to farmland. As can changes in management, or a lack thereof; the abandonment of farmland can lead to encroachment by scrubs and trees. While scrubland can be an important habitat for many wildlife species, it is not necessarily suitable for all farmland species, such as ground-nesting birds that prefer open habitats. This could lead to a change in community structure and may even lead to localised extinction of vulnerable species that rely on farmland and cannot survive in other habitats. Changes in land use through development can also impact in a similar way. Furthermore, if the land was originally woodland or wetland, for example, there may be a push to restore it to its previous habitat type, which may not be suitable for the species previously inhabiting the farmland area.

Farmland habitats also face climate change-related challenges. Changes in precipitation, increased extreme weather and increased temperatures can lead to soil degradation, reduced plant growth and changes in the availability of food, shelter and fresh water for wildlife. These factors can also impact crop production, and where this results in reduced yields, this increases the need for agricultural intensification to meet demands, further impacting the farmland ecosystem.

Hopes for the future

A change in the way farmers receive subsidies may signal a shift away from a rather bleak picture for these habitats. Previously, farmers were paid grants based on how much land they owned and farmed. This encouraged them to use as much of their land for productivity as possible. Now, however, farmers will be paid for more sustainable practices instead. Under the Sustainable Farming Incentive, grants will be rewarded for restoration of non-crop habitats, the provision of resources for farmland species year-round and reducing the use of harmful pesticides.

MARINElife: Q&A with Rick Morris and Tom Brereton

MARINElife is a science charity that conducts research on the health of our oceans by gathering information on key marine species. With the help of experienced volunteers, they carry out dolphin, whale and seabird surveys in UK and bordering waters and provide relevant, robust and up-to-date information to those working for the sustainable future of our oceans. MARINElife also runs an extensive programme of educational and outreach events, from species identification to full surveyor courses.

Research Director Tom Brereton and Trustee, Trainer and Wildlife Officer Rick Morris have kindly taken the time to answer a few questions for us.

Could you tell us about the work MARINElife does and how your charity began?

MARINElife is a charity (established in 2005) that is dedicated to the conservation of marine wildlife through research and educational activities. MARINElife grew out of the Biscay Dolphin Research Programme (BDRP), which was a survey and educational programme originally based on a P&O ferry from Portsmouth to Bilbao (1995-2010).

Today, MARINElife carries out scientifically robust surveys of dolphins, whales, and seabirds, made by experienced volunteers, on a variety of vessels at sea in UK and bordering waters, from angling boats through to large commercial ferries. The work is done in partnership with a wide range of sponsoring bodies from ecotourism through to research institutes and shipping companies.

MARINElife Surveyors by Rick Morris Photography

You survey many key marine species to monitor the health of our oceans. Could you explain a bit more about the role dolphins, whales and seabirds play in the marine ecosystem and the key threats they are facing?

Dolphins perform crucial roles in their native ecosystems wherever they’re found and function as high-level predators feeding primarily on fish and squid. In any ecosystem, carnivores near or at the top of the food chain establish fundamental order all the way down to the bottom, and their removal can have wide-ranging and highly complex repercussions.

Whales play a vital role in the marine ecosystem as they help provide at least half of the oxygen you breathe by providing nutrients to phytoplankton.

Seabirds can be a good and visible indicator of the wider health of the marine environment as they feed on many of the same species as cetaceans and are often found in association with cetaceans during feeding.

The key threats to whales, dolphins and seabirds are: whaling, climate change, overfishing, by-catch, entanglement in ghost fishing gear, noise pollution and ship strikes.

The marine realm is an important resource for many communities but is also intensely exploited. Do you believe a balance can be found between its continued use and the improvement and maintenance of ocean health?

We believe that through scientific evidence and good educational programs, cooperation with local fishing communities and everyone who depends upon the marine environment can be established to safeguard the future of our seas.

Presently, you are focusing on your small boat surveys in Lyme Bay monitoring dolphin populations. Have you noted any changes since the start of the pandemic?

Generally, there seems to be less commercial fishing activity during the day than there was a few years ago, perhaps a sign that the area has been “fished out” to some degree. There has been a notable increase in Balearic Shearwaters throughout the summer months in both years, with the Bay becoming more and more important for this species. 2020 was characterised by large numbers of Bluefin Tuna, whilst 2021 was a late season with hardly any Mackerel until September.

Bottlenose Dolphin by Rick Morris Photography

Using data collected by MARINElife, a major study published this year highlighted the importance of south-west UK waters to the Critically Endangered Balearic Shearwater. What conservation measures would you like to see put in place to help this species?

The main global threats to the species have been identified as drowning in fishing nets and predation by introduced species on their breeding grounds. For the bycatch issue, appropriate mitigation measures are urgently needed, whilst predator control and eradication measures need to be stepped up at breeding sites. Research is required on other threats including light pollution, marine plastics and climate change. More locally, shoaling pelagic fish such as Anchovy, which are key prey items, need to be protected from overfishing and disturbance of moulting flocks need to be monitored and regulated if required. Work needs to continue to identify and designate Special Protection Areas for the species, where these will make a real difference to the conservation of the species.

Author Interview with Roy Dennis: Mistletoe Winter

Mistletoe Winter is a collection of essays on our environment, covering biodiversity, habitat conservation, rewilding and individual species.

Similarly to his companion volume, Cottongrass Summer, author Roy Dennis expresses his alarm at the crisis currently confronting the natural world while balancing this with his sense of optimism about the younger generations and their fight for the crucial changes needed for the future. Drawing from his considerable experience of working in nature conservation, his essays are full of insight and originality, providing inspiration and ideas for everyone who cares about our planet and its species.

Roy Dennis has kindly taken the time to answer a few questions for us below.

Mistletoe Winter and its companion Cottongrass Summer are collections of essays on our environment and the challenges it faces. How did you find the response to your first collection and what motivated you to write this one?

I received such a lovely response to Cottongrass Summer from so many people, and such encouraging reviews, that I wanted to cover a range of other nature topics in a similar way. People remarked that they liked the storytelling way of explaining some of the real issues to do with nature in our ever-changing world and this allowed me to cover some bigger ideas in Mistletoe Winter.

In your essay ‘Deep snow, predators and prey’ you noted how the choice of language and terminology may have an impact on the rate at which the general public learns about environmental crises. Could you talk a little bit more about this here?

I was talking about the fact that there is so much excellent science being done on wildlife and ecological issues, but so much is ‘hidden’ to ordinary folk because it is in scientific journals, some of which are not open access, and often written in a formulaic way. We need much better availability of the results written by the scientists involved in plain language, which everyone can understand.

What do you think are the most important and urgent steps that we need to take in the UK to protect our wildlife and endangered species, such as the lapwing?

The most important step is to raise ecological recovery to much higher levels. I would compare it to the major recognition of timber shortages at the end of the First World War, which created the Forestry Commission; and the shortage of food in the Second World War, which created a much enhanced Agriculture Department. In the present crises, we need greatly expanded Nature Recovery government departments with really substantial budgets to restore nature. I’d recommended that 50% of our land and seas is principally for ecological restoration, and budgets need to be in line with the £45 billion we spend on military defence.

You mention young people’s role and engagement in the fight against climate change, as well as your own childhood experiences with nature. How do you think we can best encourage environmental awareness in young people?

I think young people are often fully aware of the climate and biodiversity crises – in fact, more so than their parents. The important step forward is for older people to recognise their worries and do something about it – urgently – for it’s the young that will have to suffer the consequences of our inaction.

Mistletoe Winter will be your second book published in 2021, following the
brilliant Restoring the Wild, published earlier this year. Do you have plans for any further books or other exciting projects?

Yes, I have a couple of interesting book ideas I’m mulling over, and we have wildlife projects we wish to carry out – but I’m a great believer in working up ideas quietly without fanfare and then getting on with them.

Conservation Land Management: Autumn 2021

The Autumn issue of Conservation Land Management (CLM) covers a variety of themes relevant to those involved in managing land for conservation, from the creation of bare ground habitats to incorporating climate objectives into the management of wildlife sites. Here, Assistant Editor Catherine Mitson provides a summary of the articles featured in this latest issue.

Ingleborough National Nature Reserve (NNR) covers a huge expanse of limestone grassland and pavement, acidic grassland, blanket bog and heath in the south-western Yorkshire Dales. Previously, the land had been grazed by sheep, numbers of which had doubled from the late 1960s to the 1980s while the number of cattle halved. The negative impact of sheep grazing was evident, especially in heavily-grazed areas where grasses dominated, and the only plants remaining in significant numbers were hardy species such as thyme, clovers and daisies. But an opportunity arose to reduce sheep numbers and to promote cattle grazing, and in this article Andrew Hinde, Peter Welsh and Bill Grayson describe the success of the reintroduction of cattle grazing to Ingleborough and outline the NNR’s conservation objectives going forward.

The next article brings us to Havergate Island in the Alde–Ore Estuary SSSI in Suffolk. Since 1997, spoonbills have been trying to colonise the estuary but breeding attempts failed, mainly due to the presence of and predation by foxes. But over on Havergate Island, a more secluded site with little human disturbance, spoonbill numbers were increasing. To encourage breeding on Havergate, RSPB set up elevated nesting platforms and, owing to the presence of foxes and other predators on the island, installed predator-exclusion fences. Vivienne Booth, Aaron Howe and Adam Rowland describe how the predator-exclusion fences were designed and installed, leading to the return of breeding spoonbills to Suffolk.

Christopher du Feu and Michael Gillman take us to Treswell Wood in north-east Nottinghamshire. In 2014 Nottinghamshire Wildlife Trust purchased an area of the wood that had previously been cleared for agriculture, known as the assart. Instead of planting trees, it was decided to let nature take its course and leave the assart to return to woodland naturally. Monitoring of woodland regeneration began in 2016, but in 2017 ash dieback struck the assart. In this article the authors report the results of this ongoing monitoring, and demonstrate the remarkable effect that ash dieback has had on natural regeneration.

With COP 26 fast approaching, many of us have noticed increasing news coverage of the climate and biodiversity emergencies. But on nature conservation sites, can climate objectives and biodiversity-related priorities co-exist? Heathlands, for example, are managed by techniques such as burning, a contradictory approach from a climate perspective. John Bacon addresses this dilemma, and takes a look at some initiatives in Shropshire to demonstrate how climate objectives are being incorporated into habitat management, with biodiversity still being the top priority.

The final article encourages us to appreciate the importance of bare ground habitats. Many species of spiders, ground beetles, wasps, bees and reptiles (to name a few) depend on the warm microclimate that bare ground provides for hunting, basking and nesting. Using examples from south Staffordshire, Katie Lloyd describes the process of bare ground creation, including the design, type and size of scrapes; how to maintain and manage newly-created bare patches; mitigation and other considerations to be aware of before undertaking such a project; and the benefits that this overlooked habitat provides.

In this and every issue you can expect to see Briefing, keeping you up to date with the latest training courses, events and publications, and On the ground which provides helpful tips or updates on products relevant to land management.

Other features that regularly appear in CLM include Viewpoint, a similar length to our main articles, but here authors can voice their own views on various conservation issues, and Review, which can include letters from readers or updates from our authors.

CLM is published four times a year in March, June, September and December, and is available by subscription only, delivered straight to your door. Subscriptions start from £22 per year. Previous back issues are also available to purchase individually (subject to availability).

If you are involved in a conservation project and think your experiences could be useful to other practitioners, we would love to hear from you. If you are interested in writing for CLM feel free to contact us – we will be happy to discuss your ideas with you.

COP 26: The road to Glasgow… and beyond

In just a few weeks, the UK will host the UN’s 26th Climate Change Conference, COP 26, in Glasgow. In an editorial in the October issue of British Wildlife, David Stroud, former Senior Ornithologist at JNCC and co-author of International Treaties in Nature Conservation: A UK Perspective, describes the build-up to the conference and what we can expect from the event itself. The editorial is shared in full below.

Psychologists tell us that humanity evolved to focus on immediate threats – the sabre-toothed tiger lurking in a cave – rather than to ‘over the horizon’ challenges that will affect us only at some distant time in the future. That, at least, is the suggested justification for humanity’s failure to address seriously the problem of anthropogenic climate change over the last half-century, despite increasingly definitive evidence of the existential threat it poses. The frequency of extreme weather events in recent years, however, no longer allows lack of immediacy to be used as an excuse: from flooding and wildfire to sea-level rise, the consequences of climate change are apparent here and now and they are part of the lived experience of people across the world.

The effects of global heating are not restricted to weather catastrophes. As naturalists, we are ever-more familiar with changes to our flora and fauna, as documented elsewhere in this issue (pages 13–20) and previously in British Wildlife. This presents significant challenges to national conservation policies, which have traditionally relied on essentially static networks of protected areas and protected species lists. Despite the announcement of various welcome (but limited) projects, UK governments are yet to promote or implement climate-change adaptation at the scale required to make a meaningful impact.

The October 2021 issue of British Wildlife

In August, the Sixth Assessment of the Intergovernmental Panel on Climate Change (IPCC) provided the starkest of stark warnings yet (IPCC 2021). This report was described by the UN Secretary-General as nothing less than ‘a code red for humanity’ (UN 2021). He noted that the internationally agreed threshold of 1.5°C above pre-industrial levels of global heating is ‘perilously close… The only way to prevent exceeding this threshold… is by urgently stepping up our efforts, and pursuing the most ambitious path. We must act decisively now…’ With the 26th Conference of Parties (COP 26) of the UN Framework Convention on Climate Change (UNFCCC) soon to be held in Glasgow, the international community has an immediate opportunity to act on this latest science, and to use it as a solution. But will the response be adequate?

The nearly 30-year history of UNFCCC COPs is chequered and has been (rightly) dominated by issues of international development. Essentially, when the UNFCCC was negotiated, developing countries highlighted the need for developed nations – those with the largest economies and the greatest greenhouse-gas emissions – to take primary responsibility for the global issue they had (albeit unwittingly) created by more than two centuries of carbon-driven industrialisation. For this reason, the UNFCCC’s 1997 Kyoto Protocol (of COP 3) was framed on the basis of ‘common but differentiated responsibilities’, placing the primary obligation to address the problem on developed countries (it also, importantly, recognised the contributions to climate change of greenhouse gases other than CO2).

The UNFCCC’s 2015 Paris Agreement (COP 21) made the progressive step of moving away from Kyoto’s top-down assignation of national targets, and instead established a bottom-up approach to delivering objectives through ‘Nationally Determined Contributions’ or NDCs. In essence this allows each country to put on the table what it pledges to do, hoping that this is collectively adequate. Importantly, the NDC approach was agreed by, and thus brought on board, the developing countries – still recognising ‘common but differentiated responsibilities’ while acknowledging that low- and especially middle-income countries also have individual contributions to make to the global solution.

The human development needs of the poorest countries, however, are yet to be met, as recognised by the UN’s Sustainable Development Goals (SDGs). Thus, for affluent nations such as the UK there are actually two requirements for an effective Paris Agreement: not only to offer an adequate NDC, but also to contribute to the ‘financial mechanisms’ that allow developing countries to skip dirty, greenhouse-gas-emitting industry and move directly to green economies. ‘Resource mobilisation’ from the developed world will therefore be a central focus of COP 26.

Media commentators have been calling recently for binding quotas to be agreed in Glasgow. While theoretically desirable, this will not happen and it misunderstands the complexities of the global political process. Should there be a World Government at some point, such a prescriptive approach might be achievable – but for now it lives in fantasyland (along with alternative economic systems). The reality is, regrettably, much messier and is here for the foreseeable future.

At COP 26, the UK has a unique responsibility to ensure a successful outcome. Not only does it have to contribute an NDC of significant ambition as one of the world’s largest economies, but as conference chair the UK has a crucial cheerleader role, with an onus to encourage all other countries to deliver ambitiously, too. Decisions at the COP will, as is the norm for such meetings, be taken by consensus, which leaves a real risk of lowest common denominator decision-making because all countries effectively hold a veto. The role of the UK diplomatic services here is critical to build momentum, impetus and pressure (as was that of France ahead of 2015’s COP 21). They also have a vital job in gaining prior intelligence from other countries and working to fix problems and issues ahead of time through face-to-face dialogue in other capitals. As at all intergovernmental COPs, most of the content of decisions is developed well beforehand, while the conference itself is used to finesse the details and formally sign off the final texts. With (we hope) all 197 Contracting Parties attending and just a few days available together in Glasgow, there is no time to do otherwise.

Parties will already have prepared their broad national negotiating positions over the course of the last year, not least because for a meeting of such significance these will typically need to be agreed by the head of government. Many parties work together, giving them greater collective influence. National positions further evolve within regional and other negotiating blocks, including the 27 member states of the EU; the G77 (a coalition of 134 developing countries) and China; the African Group; and the multiple Small Island Developing States which, faced by pressing existential impacts from rising sea levels, have become an increasingly influential political force in climate negotiations.

Yet ultimately, while civil servants can prepare much of the ground, at the COP the tough, final negotiations and trade-offs will be undertaken by heads of government and their ministers. In this, simple peer pressure is important: no national politician likes to be presented as internationally unambitious. And personal relationships, as in any negotiation, are key to success.

Public pressure can also play an essential role by creating a political climate in which it is easier to commit to difficult things when they are presented as ‘the desire of the people’. The last few years of school strikes and other radical actions have demonstrated great public concern, rendering it increasingly difficult, for European leaders at least, not to engage. Hence, the environmental community has an important lobbying role, reminding politicians of what is expected from them, not just ahead of the COP but crucially after it as well, and holding governments globally to account. Commitments are easy to make, but also easy to forget (especially when they involve tough policy changes), and an important agenda item at COP 26 will be the first global stocktake on progress in implementing the measures agreed in Paris.

Beyond governments, contributing to the necessary profound societal change involves all of us. The latest form of climate-change denial is to accept the reality but to make no consequential alterations to one’s lifestyle: ‘business (and life) as usual’. Yet everyone will need to make changes – not least to rediscover the much-anticipated (but so far elusive) ‘new normal’ that was predicted to emerge from the Covid-19 pandemic. This will include switching urgently to more sustainable modes of transport, insulating our homes, changing diet and, critically, reducing consumption and having simpler lifestyles: buy less and live more. In promoting such behavioural changes, the environmental community has an important leadership role within society. Gandhi stressed the need to ‘be the change you want to see in the world’. Exactly.

Author Interview with Stephen Littlewood: Wild Mull

Wild Mull: A Natural History of the Island and its People guides the reader through the world of the Isle of Mull in its glory, considering every facet of the island’s natural history, diverse species and stories of past, present and future.

Mull is a seaborne landscape off the west coast of Scotland, displaying uncommon biodiversity and full of rare wildlife experiences, but today it faces some of its greatest challenges. With superb illustrations and illuminating text, Wild Mull is testimony to the power of wild places and the duty we have to protect and learn from them.

Stephen Littlewood kindly agreed to answer some of our questions below.

Mull mountainscape across Loch na Keal by Martin Jones

Could you tell us what inspired you to write this natural history of the Isle of Mull and its people?

We live in an era when wildlife is being pushed more and more into the margins, and many people are starved of the experience and understanding of wild places. In this context, there is a consensus that Mull is formidably equipped to display a concentration of land and marine species that is very rare today. It is also a relatively accessible destination. Consequently, the island and its surroundings have become significant attractions for a burgeoning population of wildlife tourists and, it must be said, for the tourism industry which has prospered on the back of a fascination with the so-called ‘wild’. Today, Mull’s reputation for delivering outstanding and intimate associations with many iconic British species draws people from far and wide. However, until now there has been no single resource that explains how Mull came to this position, or what it is about its aggregation of species and habitats that makes it so outstanding. I felt that it was high time to rectify that, but in doing so it was important to address some of the questions that are often overlooked during the pursuit of the profound pleasure to be gained from embracing nature in cherished land and seascapes. The book was always intended to be as much a history, an explanation and an exploration of this special place, as it was a guide to its species and habitats.

Visitors typically arrive on Mull with a wish-list of species to see. That list is invariably topped by eagles (white-tailed and golden), otters, puffins, and cetaceans. What people tend to be less appreciative of, or often not at all interested in, is the backstory both to these species and of the multitude of supporting flora and fauna. All of them are equally beautiful and extraordinary in different ways, and it is the sum of their parts that enables the headline species to thrive. I wanted to encourage the reader to explore as much of Mull’s complex biodiversity as possible, whilst also explaining how, in such an apparently injury-free landscape, it is constantly under pressure and subject to continual interventions by people, in the same way as anywhere else. To do so the book had to be factual but at the same time attractive and not overbearing. This meant that it would have to deliver a visual thrill; to make all of it, even the smallest elements, tangible and exciting. I also knew that Martin could sprinkle that magic, embroider the broad design concept, and embellish the text with the kind of high-quality photo images that would prove irresistible to the potential readership. He has done this wonderfully well.

You mention that human intervention has had a profound effect on Mull. Could you tell us a little more about the historical relationship between humans and the environment on the island?

Mull’s environment isn’t perfect, or unblemished. Most of that is down to the fact that people have been surviving on, profiting from, and ‘improving’ it for 10,000 years. If we were going to tell an honest story of the island’s natural history, it had to include the role of people, for better or worse, in shaping it. To begin with, I thought that this would be a tale largely of land use, of subsistence arable farming, grazing by domestic animals, wholesale planting and harvesting of cash-crop conifer plantations and so on. Of course, these are significant elements in the story, but only when I started to examine the historical record did I realise the extent to which species have been manipulated, consciously and unconsciously, by human interventions that have fundamentally impacted the flora and fauna over time. The picture of what we think of as a natural biodiversity, not only on Mull, isn’t necessarily as we perceive it. An extraordinary proportion of our flora and fauna has been introduced, exterminated, or tampered with. What I find interesting is that each time these actions have occurred they have been judged by the social, moral or economic expediency of the age. Today, we may feel confident that we know the right and wrong ways of addressing biodiversity issues, but one wonders if future generations will have a different perspective again.

The pine marten is flourishing on Mull, which is considered by some to be a success story, given their critical status in England and Wales. However, you highlight their potential negative impact on many of Mull’s endangered bird species. How does Mull plan to tackle this conservation conundrum?

In short, Mull doesn’t plan to tackle it at all nor, I think, is it a topic that is widely discussed. The pine marten is a very recent arrival on the island, and although it was not ‘formally’ introduced, it is generally accepted that it is here to stay. Its presence is mostly felt by the inhabitants to be desirable, so hopefully, its impact upon other species will not be to drive them beyond sustainable populations. Its role as a new predator does raise interesting questions, however. It is certainly thriving, but nobody is monitoring the impact of its reintroduction, nor the size of its population. It is a protected species in Scotland, so, therefore, cannot be deliberately trapped, whilst at the same time, the Scottish Environment Protection Agency (SEPA) have said that, because its introduction was never officially sanctioned, if it is accidentally caught in mink traps, for example, it should be removed from the island as an illegal immigrant and liberated elsewhere. We don’t really know if its migration is good or bad for Mull’s wildlife, and we don’t have any inclination to find out. I find this a confused response and a fascinating conundrum in the light of current approaches to the restoration of our damaged environments.

Tourism, particularly ecotourism, contributes a large proportion of the island’s economy. However, negative aspects of ecotourism, such as overuse of areas, can lead to environmental damage. What measures are being taken to keep tourism sustainable?

Ecotourism is probably now the largest contributor to the economy of Mull, but again this isn’t a question that is really generating much deliberation about the future or consideration of potential interventions. There are parking issues, particularly in the centre of Tobermory, which have been the subject of debate and are likely to result in the community and local authority trialling solutions to excess traffic in urban areas. However, in terms of ameliorating traffic growth on the roads, the impact of ‘wild’ camping, or the increasing pressures on species such as puffins and otters by wildlife photographers and so on, there is little formal debate and very little coming forward by way of attempts to make tourism more sustainable to protect the environment. It was interesting, whilst writing the book, to reflect upon the significant behavioural responses of wildlife during the Covid-19 lockdowns. There were many discernible changes, both as a response to restrictions upon tourism and the subsequent lifting of those restrictions.

Do you have any future projects planned that you can tell us about?

Mull could be likened to an accessible ‘mini laboratory’ with the potential to explore many environmental issues which are being played out on a much bigger stage. I would like to use the prism of Mull to address some of the big questions that arose in writing the book, although unpacking and making sense of the many wicked issues that come to mind is a complex and hazard-strewn path which would be a wholly different kind of journey. In the meantime, perhaps Martin and I will further develop some of the core themes of this book, which continue to fascinate and engage an ever-increasing number of interested individuals.

Climate Challenges: 3. Fossil Fuels

In the lead up to the 26th UN Climate Change Conference of the Parties (COP26) in November of this year, we are writing a series of articles looking at some of the toughest global climate crisis challenges that we are currently facing. This article looks at the use of fossil fuels and their contribution to climate change.

What are fossil fuels?

Fossil fuels include coal, natural gas, heavy oils and petroleum. They are formed from the decomposition of carbon-based organisms that were buried millions of years ago. This created carbon and hydrogen-rich deposits below the earth’s surface, which can be extracted and burned for energy. Fossil fuels are non-renewable, a finite resource that is being used much faster than can be replenished, but this type of fuel currently supplies around 80% of the world’s energy.

How are they extracted and what are the impacts?

There are several methods of extracting fossil fuels, depending on the type, amount and surrounding area. The main method for extracting solid fossil fuels, such as coal, is mining, where buried resources are exposed by digging or scraping. This can be underground, on the surface or even at sea. Land-use changes associated with mining, such as the construction of access roads, processing plants and other facilities, and the mining itself, have a wide range of environmental impacts. The extraction of coal can pollute local water sources with toxic chemicals and heavy metals, reduce the quality of soil, involve excess dumping of rock and soil and strip the land of vegetation. There are also some very destructive techniques such as the use of explosives, which can have a widespread impact on the local wildlife.

For liquid or gaseous fuels, the method most often used is drilling. This has similar land-use change impacts to mining, but drilling also involves pipelines, the building of which can cause thousands of miles worth of damage. There is also the threat of spillage, such as recently occurred in North Dakota, where nearly 41,000 gallons of wastewater was spilt from a broken pipeline. Oilfield wastewater, also called produced water, contains saltwater and drilling chemicals, including heavy metals. It is not drinkable and can have serious environmental consequences when it’s spilt.

Fracking is another method used to extract gas. The environmental impacts from this method include the release of carcinogenic chemicals into water sources, earthquakes and reduced water availability due to the high volume needed for the fracking process.

What happens when we burn fossil fuels?

Burning fossil fuels generates energy, which is converted to electricity and used for industrial processes and transportation. Since the industrial revolution, our use of fossil fuels has been steadily increasing. The use of fossil fuels is thought to be the primary cause of climate change. Burning these fuels releases carbon dioxide and other greenhouse gases into the atmosphere at a much faster rate than it can be removed by the carbon cycle. These gases accumulate in the atmosphere, intensifying the greenhouse effect and increasing global average temperatures.

Burning fuels also increases the acidity of precipitation, causes ocean acidification and emits air pollutants, causing respiratory disease.

What are the alternatives?

There are many different alternatives to fossil fuels, each with their own benefits and drawbacks. From hydrogen gas, tidal energy, wind energy, geothermal power, biomass energy, biofuels to wave and solar power, there are several options that companies and countries can use to reduce their carbon footprint. The benefits are reduced direct emissions, the potential for lower fuel prices and that they are renewable energy sources. However, some have their own negative impacts on the environment. For example, wind farms can be harmful to birds, some solar panels are manufactured using heavy metals and are difficult to recycle, and hydrogen gas is mostly produced from fossil fuels. Therefore, simply switching over from fossil fuels to renewable is not an easy process.

However, a higher percentage of the UK’s electricity was powered by renewable energy than fossil fuels in 2020. Renewables powered 43% of our electricity compared to the 38.5% powered by fossil fuels. Together with nuclear power, 59% of the UK’s electricity was powered by low carbon sources. This demonstrates that large-scale use of renewable energy is possible and that we are taking steps on our way to becoming a net-zero country.

What is net zero and is it really the solution?

Net zero is the balance between the amount of carbon dioxide and other greenhouse gases produced and the amount removed from the atmosphere. This can refer to the emissions of individual people, companies, countries and the world. It does not mean that fossil fuels will no longer be used however, it instead means that the amount of emissions released is the same as the amount removed. This can be achieved without completely cutting out our emissions output by increasing the removal of greenhouse gases through techniques such as planting trees or capturing carbon during industrial processes. While finding a balance is an important step in tackling climate change as it will reduce global warming, it is not the final solution. The continued use of fossil fuels will have other negative environmental implications, even if our emissions are balanced.

True zero refers to the complete removal of carbon-emitting fuel types from our energy supply or carbon offsetting when using these fuels when renewable energy supplies fall short. This also includes cutting all greenhouse gas emissions, including from sources other than fossil fuels. Carbon negative refers to a carbon footprint that is less than neutral and therefore is removing more carbon dioxide from the atmosphere than it is adding. Only two countries are thought to have reached net zero, Bhutan and Suriname, and both claim to be carbon negative. However, both countries still use fossil fuels.

We are already seeing the effects of climate change and the increased average global temperatures. At the 1.5°C increase that the Paris Agreement aims to limit the rise to, we will see even more serious consequences (you can read more about this in our blog: Climate Challenges: What is COP26 and Why is it Important?). One way to truly tackle climate change is to begin reducing atmospheric carbon and greenhouse gases to pre-industrial revolution levels, hopefully allowing average global temperatures to also reduce to pre-industrial revolution levels. To achieve this, more countries must become either true zero or carbon negative.

Summary

• The extraction and burning of fossil fuels have serious negative environmental consequences, including temperature increase, air pollutants and water contamination. The amount of greenhouse gases in the atmosphere has steadily been increasing since the industrial revolution.
• There are multiple alternative energy sources, including renewables, but these can also have negative impacts on the environment. They powered more electricity in the UK than fossil fuels in 2020.
• Net zero is the balance between greenhouse gases produced and the amount removed from the atmosphere. True zero refers to cutting all carbon and greenhouse gas emissions. Carbon negative means removing more carbon dioxide from the atmosphere than is being added. One way to tackle climate change is for countries to aim for true zero or carbon negative to reduce the amount of greenhouse gases in the atmosphere.

The Fate of Butterflies and Moths

Across the world, there have been significant declines in butterfly and moth populations. Since 1976, 76% of UK butterfly species have seen a decrease in abundance or distribution, with the abundance of larger moths declining by 33% since 1968. This trend is echoed across UK biodiversity, with 41% of all UK species declining since the 1970s. Butterflies and moths are clear indicators of the broader health of the environment; their decline is a stark warning about our natural world.

The UK has 59 butterfly species, 57 of which are resident. There are around 2,500 species of moths in the UK, split into two groups: larger macro-moths and smaller micro-moths. Almost 70 species of butterfly and moth have become extinct in the last 100 years. A variety of threats have contributed to these extinctions and the general decline of other species, including the destruction of habitats and major land-use changes, such as the intensification of agriculture. Climate change, chemical pollution and artificial light at night have also all be identified as threats to UK populations.

Butterflies and moths have an intrinsic value in their own right, but they are also an important component in many ecosystems. They provide environmental services, including pollination and pest control and are prey for many other species, such as birds, bats and other insectivores. Butterflies and moths are also important ‘model’ organisms, used for centuries to investigate different areas of biological research and are key to understanding many diverse fields, such as pest control, mimicry, genetics and population dynamics.

The Big Butterfly Count 2021

Butterfly Conservation, a UK nonprofit environmental charity, is determined to reverse this decline. Their vision is a world where butterflies and moths thrive and can be enjoyed by everyone, everywhere. To help with the assessment of the health of our environment, Butterfly Conservation runs an annual nationwide citizen science survey, the Big Butterfly Count. Launched in 2010, it is the world’s biggest survey of butterflies.

Big Butterfly Count 2021 ran between 16th July and 8th August (read our blog to see how our NHBS staff got on this year). The results of this count showed that the overall number of butterflies recorded per count is at its lowest since the event began. Over 150,000 counts were registered this year, more than ever before, but the results showed that the populations of some of our most-loved species, such as the peacock butterfly (Aglais io), are suffering. Luckily, it’s not all bad news, as some species, such as the marbled white (Melanargia galathea), appear to be bouncing back from last year’s low numbers. But the significant, long-term decline of many butterfly and moth species in Britain is alarming.

Butterfly Conservation’s new strategy

In their new 2021-2026 strategy, launched in October 2021, Butterfly Conservation outlines a bold, ambitious road map to bringing abundance back to nature. After 16 months of reviewing their position in butterfly and moth conservation, they have defined three new strategic goals:

Reduce the number of threatened species of butterflies and moths by half,
Improve the condition of 100 of the most important landscapes for butterflies and moths,
Transform 100,000 wild spaces in the UK, not just for butterflies and moths, but also for people.

To help them deliver their strategic goals, Butterfly Conservation have five initiatives. The first initiative is focused on recovery, through refocusing their science program to increase the understanding of why species are declining and how to recover their populations. They will also establish a new Threatened Species program, which will target conservation action for 65 species at serious risk. Butterfly Conservation will also expand their monitoring program to follow species recovery and gather data on a country-wide level. By 2026, they hope to have increased their species recovery actions by 65%.

The second initiative aims to inspire and enable more people to enjoy the natural world by improving access to learning, particularly for younger audiences. The third initiative is focused on uniting for wildlife, and the fourth is to tackle the threats species face, such as artificial light at night. They’ll achieve these goals by collaborating with a network of supporters and increasing their investment in research by 80% to establish five habitat quality indicators to better understand the impact of conservation work or policy changes. The final initiative focuses on managing land sustainably, by creating a land management advisory hub and delivering and demonstrating best practice land management for butterflies and months across landscapes.

Butterfly Conservation believes that the next five years are key and, through their bold new steps to conserve butterflies and moths, they can help to restore biodiversity, mitigate the climate crisis and start to rebuild the relationship between us and the natural world.

New Networks for Nature: Q&A with Amy-Jane Beer

Amy-Jane Beer, a biologist, writer, editor and member of the steering group for New Networks for Nature, kindly took the time to talk with us about the work they do and the importance of their annual event, Nature Matters.

We discuss the role of the creative arts in engaging with the natural world, the political priority of wildlife and how best to get involved.

Firstly, could you tell us about the work that New Networks for Nature does?

Our entire focus is an annual event called Nature Matters: not quite a festival, not a conference, not a symposium, not an exhibition, not a variety show… but with elements of all these. It is two days and one evening of hugely varied dialogues, debates, readings, performances and displays about and in concert with nature. Our contributors are writers, artists, poets, filmmakers, activists, scientists, naturalists, musicians, photographers, conservationists and sometimes politicians and entrepreneurs. Our audiences contain many more of the same, plus publishers, journalists, producers, campaigners, representatives of major NGOs who use the opportunity to make new connections.

You are a relatively new charity, founded in 2009 and registering in 2016. How did the charity start and what are your hopes for its future?

The first event, held in 2009, was the brainchild of our founders: Jeremy Mynott, Mark Cocker, John Fanshawe and Tim Birkhead – four big thinkers who, in Jeremy’s words ‘shared the conviction that wildlife had a far richer role to play in the human experience than that defined by science or economics alone.’ They decided to try and reach more like-minded, creative souls and rapidly realised that an event offering both inspiration and social connection was a powerful way to build a network. By 2019, pre-COVID, that initial one-day event with 44 attendees had grown to a two and a half-day version with 30–40 contributors and an audience exceeding 250. This is about as big as we can manage on a voluntary basis with a minuscule budget funded purely by ticket sales. It’s rewarding but exhausting for the organisers, and the risk of burnout is very real. So the next phase for us as an organisation has to be sourcing funds that will allow us not only to offer an ever more diverse and accessible event but also to pay for some of the services that currently push us to our limits. It may be we offer a Friends of NNN subscription, seek carefully vetted sponsorship, or grant funding that doesn’t compromise our ethos or creative freedom.

One of your main aims is to challenge the low political priority that is placed on the natural world. Why do you think that there is so little importance placed on wildlife and nature nationally?

As a society we’ve come to take nature for granted, living lives so removed from the true sources of everything that sustains us we forget we’re not only dependent on nature, but part of it. That disconnect means that when we encounter problems, we often come up with solutions that target symptoms rather than the root cause. And the cause, almost every time, is that vast rapacious monster of global capitalism, to which politicians are wedded. Among the most toxic spawn of capitalism is a media that has reduced politics to a frantic minute-by-minute battle over the next headline. How can politicians possibly tackle the big issues when they’re doing that? In the current system, taking time to engage deeply with nature has become an almost subversive act, because it leads, inevitably, in my experience, to a recognition that we need a wildly different path.

Your upcoming event, Nature Matters, is an annual creative celebration of nature. How important do you think the creative arts are for exploring and raising awareness about the environment?

The creative arts have a critical role to play in bringing us home to nature. And I say that as a former scientist who ‘jumped the fence’. Creativity was an aspect of my education that was horribly neglected. It’s all well and good to absorb information – to document and analyse and theorise. But in order to know what to do with all that, we need wisdom, emotional intelligence. We need stories, and we need huge amounts of love because love motivates and emboldens us like nothing else. Art makes sense of knowledge. Art asks questions science cannot and is free to go where science cannot see its way. Art lights up some of the dark. And wow, it’s getting dark right now.

This event has a huge varied list of sessions, from nature writing courses to panels on plastics in the environment and a session on nature and spirituality. What are the main goals that you want to achieve through Nature Matters?

New Networks for Nature does what the name suggests. It is mycelial activism. It connects people, with nature and with each other. The events are entertaining but they are not entertainment. Attendees come to listen to and admire amazing people, but also to meet and link to them. We like to think that everyone in the room at a NNN event will go away inspired but also having inspired others. I started attending about 8 years ago, very shyly, but through a few mutual friends was introduced to others and now every year I go along with the express purpose of meeting more people. As the Irish saying goes – a stranger is a friend you haven’t met yet. At NNN, a stranger is a link to many more people, more voices for nature, more opportunities to disseminate, mobilise. Many of my NNN connections have become deep friendships – but they are also highly intentional and purposeful relationships. I cultivate them because, if we can take any lesson from the current political castes, we desperately need a chumocracy for nature.

For any readers interested in your charity and its aims, what are the best ways that people can get involved?

Come along! The attendees are as much part of the network as those on stage at any event. We bust a gut to keep the cost of attending to a minimum and make it accessible. There are always opportunities to ask questions, to socialise and to connect. As a rule, we don’t invite applications to perform or speak. Each event is organised by a different team and the programmes are themes and very organic. There are always a few big names in the mix but increasingly we tend to feature up-and-coming contributors or less exposed specialists – and to be honest, those more niche sessions are often where the real ‘wow’ moments happen. Unlike other festivals, we’re not really part of the promotion round – no one will get rich or famous or achieve a bestseller by appearing, or achieve social media celebrity. But we hope that everyone will go away with fresh fire in the belly, new light in the mind, and a list of names and allies to add to their personal network for nature.

Nature Matters 2021 will be held in Bath on 19th-21st November and will feature an exciting list of contributors, including ecological activist Satish Kumar, popular ornithologist David Lindo, breakthrough nature writer Nicola Chester, musician and curlew campaigner David Gray and young environmental campaigners Kabir Kaul, Holly Gillibrand and Bella Lack.

The NHBS Introduction to Habitats: Urban and Suburban

The next habitat we will be exploring in our Introduction to Habitats series is urban and suburban habitats. These are extremely diverse, from parks, gardens, cemeteries and bare ground to highrises, bridges, landfills and houses. Due to this wide diversity, urban habitats are often extremely fragmented, with small, isolated patches surrounded by unsuitable areas. These patches are also often highly disturbed, by light, people, pets, cars and other anthropogenic activities. Some species also have to deal with reduced availability of food, due to the limited plant life, and fewer nesting and breeding spaces. Much of the surfaces in the urban environment have been altered, covered in concrete, roofing tiles, and tarmac. This changes the amount of rainwater that can infiltrate the soils underneath, as well as how much heat from the sun is absorbed. The temperatures can be higher in urban areas, particularly when there is little to no tree coverage to provide shade.

To survive in an urban environment, species must be adaptable. Many studies have found key behavioural and physical differences between urban and rural dwellers of the same species. For example, birds have been found to sing higher, longer and louder in cities than in the countryside. Generalist species are more likely to be able to exploit these habitats as they can occupy wider ecological niches. Specialist species can have more restricted diets or need more specific conditions to develop or reproduce, making them less able to adapt to changing environments. Those able to transition from natural to man-made habitats, however, may actually see large fitness benefits, due to fewer predators and, for some species, abundant food supplies.

Gardens and public green spaces can often be a refuge for many urban species, providing food, shelter and protection from other disturbances. But overly manicured gardens and parks do not provide the resources necessary for many species to survive. Wildflowers, hedges, shrubs, trees and other native vegetation are needed to boost insect numbers, along with limiting the use of harmful herbicides and pesticides. Many other species rely on insects for food, and so increasing insect populations benefits other species throughout the food web.

What species can you find here?

Flora:

Cow Parsley (Anthriscus sylvestris)

This species is a member of the carrot family and is commonly found on verges, hedgerows and less intensively-managed green spaces, with a preference for shaded habitats. It is a fast-growing plant, that appears in the summer before dying back, and its white flowers are clustered together in an umbrella-like shape. They are a great food resource for many invertebrate species, as well as for rabbits. There are several similar-looking plants, including the poisonous hemlock (Conium maculatum), although hemlock has distinctive purple blotches on its stem.

Three-cornered Garlic (Allium triquetrum)

This is an invasive species, often found along verges, roadside banks, hedgerows and on waste ground. It can form dense colonies and are spread naturally by ants. Its white flowers have a green stripe on each petal and a garlic/oniony smell. They are edible, tasting similarly to spring onion or chives.

Common Chickweed (Stellaria media)

This plant has multiple common names, including chickenwort, maruns, craches and winterweed. They form large mats and are found in many gardens and fields. It has one line of fine hairs on its stem, with oval leaves and small white flowers. Chickweed was used in folk medicine as a remedy for pulmonary disease and several itchy skin conditions. It is even prescribed today by modern herbalists for many other conditions, although not all these uses are supported by scientific evidence.

English Ivy (Hedera helix)

This is a climbing plant that can often be found on walls, buildings, trees and other man-made and natural structures. It is an evergreen species that can also grow as groundcover when there are no vertical surfaces. The flowers are a greenish-yellow colour and the fruits, which ripen in late winter, can vary in colour from purple-black to orangy-yellow. They are an important food source for many insects and birds, particularly in autumn and winter, and their foliage is also browsed by deer.

Fauna:

Feral Pigeon (Columba livia domestica)

There are several species of pigeon in our urban areas. Feral pigeons, also known as city or street pigeons, are descended from the domestic pigeon, a subspecies derived from the rock dove (Columba livia). They have substituted their natural habitats of sea cliffs with ledges on buildings and other man-made structures. They have a wide variety of colours and patterns compared to the rock dove, but urban pigeons tend to have a darker plumage compared to individuals in rural areas.

Red Fox (Vulpes vulpes)

An iconic urban species, the red fox is one of our largest land predators. Usually living in groups or pairs, they feed mainly on small mammals and birds, but also amphibians and fruit. In urban areas, they are very successful scavengers, helped occasionally by people who leave food out for them. They are more common in less dense suburban areas but have been found right in city centres. It is thought that the movement between urban and rural fox populations is quite fluid.

European Hedgehog (Erinaceus europaeus)

Another iconic British species, the hedgehog has seen severe population declines, though true population estimates are difficult, due to the lack of data and their elusive nature. In the 1950s, population estimates put the number of hedgehogs in the UK at 36.5 million (although this is not thought to be accurate), which is now thought to have dropped to 1.55 million by 1995. It is believed that populations are still declining, but there are still no reliable methods for estimating the true numbers. They face several threats, including habitat loss, chemical use in gardens, cars and a drop in invertebrate populations.

Peregrine Falcon (Falco peregrinus)

This bird of prey is not only the fastest bird in the world, but also the fastest member of the animal kingdom, clocking up a dive speed of over 320km/h. Their populations suffered after decades of persecution and pesticide use, but their numbers have begun to recover. They nest in tall buildings, bridges and pylons, and prey mainly on pigeons but also collared doves, blackbirds and starlings.

Garden Snail (Cornu aspersum)

A wide variety of invertebrates can be found in urban and suburban habitats, particularly gardens and parks. The garden snail is a common visitor to our lawns, plants and vegetable patches. They’re often considered a pest due to the damage they cause to leaves and fruits but they play a vital role in the health of our soils. They help decompose plant matter, allowing for the cycling of nutrients back into the soil. Snails are also an important food and calcium source for many animals, such as birds.

Urban and suburban environments are also home to many garden bird species, as well as bats, butterflies, moths and spiders. For more information on these, check out some of our guides to UK species identification.

Threats

Urban and suburban areas are becoming more and more densely inhabited as more of the UK’s population moved into towns and cities. This increases the levels of disturbance, from more cars on the road, more noise, light, waste, pets and people. Higher disturbances decrease the ability of species to survive, as they are less likely to feed, develop and reproduce successfully. It can also increase the likelihood of direct mortality.

With a rising human population is an increasing need for more housing and infrastructure. Consequently, this reduces the amount of undeveloped and semi-natural areas; fewer green spaces and the over maintenance of gardens and parks are serious threats to biodiversity in urban habitats.

Public opinion can also threaten urban wildlife. Many species that have managed to colonise the urban environment are considered pests and there are often calls to eradicate them. Fox culls are a controversial suggestion, with many people wanting a way to control the populations and reduce the damage they cause, while others are concerned with animal rights. Additionally, there are suggestions that culls are ineffective, as removed foxes are often replaced by another individual, with no change made to urban population numbers.

What can you do to help?

There are several simple steps you can take to help improve urban biodiversity. You could plant more native plants, reduce the chemicals you use and decrease how often you mow your lawn. Placing bird feeders, nests, and other shelters are also ways that can help wildlife. On a bigger scale, you can urge your local council and government to help too. They could increase the areas of green space and tree cover, and manage roadside verges with nature in mind. Another important step is to decrease light and noise pollution. With some simple steps, we can help to increase the suitability of urban habitats for many wildlife species.
