Policy

Oil-rich states should pay a climate tax, says Gordon Brown. The ex-prime minister has argued that soaring oil prices have caused an inordinate transfer of wealth to oil-rich states from the world’s poorest countries, with global oil and gas revenues soaring to a record $4 trillion. His suggestion of a $25 billion levy would be used as part of a climate fund for poorer countries who are disproportionately affected by the impacts of climate change.

Conservation in action

Several Wildlife Trusts have launched a new Welsh-English project to restore nature and boost rural prosperity across the historic Marches region. The name of the new project “Wilder Marches” describes the unique natural and cultural landscape spanning the Welsh-English border region. The region measures approximately 100,000 hectares and includes a wide range of natural habitats including ancient woodlands, peatland, flower-rich meadows, and wood pasture. There are also areas of intensive farming and forestry in the region, and the project involving the Herefordshire, Montgomeryshire, Radnorshire and Shropshire Wildlife Trusts seeks to encourage regenerative farming and local sustainable food production.

Hampshire County Council has secured funding to save endangered UK orchids. The council has secured £98,000 from Natural England to aid its nature recovery project aiming to boost Red- and Long-leaved Helleborines, some of the UK’s rarest orchids. The county contains the East Hampshire Hangers, known for its rare ancient woodland, which provides a habitat for the rare orchids.

Science and research

Psychologists have received funding for a three-year project to investigate meerkat responses to human emotions. The scientists at Nottingham Trent University are seeking to better understand the impact of zoo visitors on animals. The research will investigate whether meerkats demonstrate empathy by mirroring people’s emotions. They hope that the study will improve our understanding of human-animal interactions and may have implications for how zoo animals are managed.

Carbon offset schemes in the United States may be ineffective according to new research. Researchers looking to assess farmer perspectives on soil carbon offset programmes put in place since 2017 found that farmers were largely using the schemes as “gravy on top” of what they were already doing. They largely considered payments to be too low to incentivise new adoption of practices that would increase carbon sequestration. As a result, carbon credits have largely been generated from farmers who were already motivated to improve soil and crop health with the aim of securing long-term economic sustainability.

Extinction risk

Global rhino numbers are recovering despite poaching and habitat loss. In a win for conservation, rhinoceros numbers have bounced back to 27,000, new figures show. Black Rhinos, native to east and southern Africa, and Southern White Rhinos, found in the south of Africa, have seen an uptick in their numbers since last year. The increase has been attributed to efforts by conservationists to establish new populations which have continued to grow. Javan and Sumatran Rhinos, however, appear to remain on course to go extinct with only tiny pockets remaining in southeast Asia. Experts believe there may be as few as 34 remaining in a fragmented forest landscape where finding mates is increasingly difficult.

One in six species are at risk of extinction in Great Britain, according to a new report. The 203-page State of Nature report, produced by more than 60 conservation organisations, found that 16% of 10,000 amphibians, birds, insects, mammals and plants are threatened. Iconic species such as the Turtle Dove and the Hazel Dormouse are among the list. Nature conservation organisations urge more investment in nature and an increased uptake of environmentally-friendly farming practices. Studies have shown that such practices can boost both production and biodiversity, likely due to the increased presence of insects that pollinate plants. The government has highlighted its pledge to protect 30% of land for nature by 2030, but conservationists have argued that more needs to be done to reverse declines.

Climate crisis

Antarctic sea ice is at a ‘mind-blowing low’, experts have warned. The quantity of sea ice surrounding Antarctica is far below previous winter levels. The total area of ice this year measures 1.5 million square kilometres less than the September average, a reduction equivalent to five times the size of the British Isles. Polar experts have warned that such low levels of sea ice could have major global consequences. Antarctic sea ice regulates the earth’s climate by reflecting light back into the atmosphere and cooling Antarctic waters. Dark areas of the ocean exposed as sea ice melts absorb sunlight and this leads to further warming.

UK firefighters are heading to Spain for specialist training after a twofold increase in recorded wildfires last year. Once a rarity in the UK, the EU’s Copernicus earth observation system has recorded the burning of 126,618 hectares since 2006. Accordingly, UK fire services are investing in new equipment and specialist training with some firefighters being sent to Catalonia – a region with a long history of tackling blazes. With temperatures exceeding 40°C for the first time last summer, the expectation is that wildfires will continue to become both more frequent and extreme.

Policy and diplomacy

The House of Lords will debate mandatory Swift bricks in England. New homes may be required to build Swift bricks into new homes if the amendment is passed in parliament. The hollow bricks are unobtrusive and are relatively easy to install. The presence of these bricks in new homes would help to revive a rapidly declining Swift population and other red-listed cavity-nesting species such as House Martins and Starlings. Swift populations have declined by more than 60% since the mid-1990s.

The UK government is preparing to revoke the ban on new onshore windfarms, according to reports. New guidance will require action from developers on the concerns and suggestions of residents, and council approval will depend on community support. The new rules will also give local authorities more discretion over the location of new onshore projects. Since 2015, there has been a de facto ban on new onshore windfarms as only a single objection is needed to prevent construction.

African leaders demand more support and financing as the first Africa Climate Summit opens. Africa has a population of 1.3 billion people and is projected to be worst hit by the effects of the climate crisis, despite contributing relatively little to the problem. Consequently, frustration has mounted in some countries at being asked to develop in cleaner ways than richer, more polluting countries.

Climate crisis

Respiratory illness patients are most at risk from climate change, according to an expert report. People with conditions such as chronic obstructive pulmonary disease (COPD) and asthma are particularly vulnerable to the effects of climate change. Higher temperatures and more frequent extreme weather events will likely lead to an increase in airborne allergens, air pollution, humidity and mould. Babies and children, whose lungs are still developing, are thought to be particularly at risk.

Groundwater depletion rates could triple in India as climate warms, according to researchers. A recent study by researchers at the University of Michigan has revealed that rising temperatures have led to an increase in the withdrawal of groundwater for irrigation by farmers in India. This could result in tripled groundwater loss by 2080, posing a threat to food and water security, as well as the livelihoods of over a third of India’s population of 1.4 billion.

Science and Technology

Scientists have discovered a technique for turning plastic waste into tiny bars of soap. The researchers found that it was possible to “upcycle” plastic waste into high-value surfactants. Surfactants are a key ingredient in a range of products from lubricants to soaps and detergents. Only around 10% of plastic waste is recycled and so experts are increasingly exploring solutions for turning waste into valuable materials. The technique only produces tiny amounts of surfactant at a time, but the hope is that the process can be scaled up in the future.

Extinction Risk

St Kilda has seen a dramatic fall in seabird numbers. Since the previous census in 1999, there has been a 64% decline in seabirds on the remote archipelago west of Scotland. The National Trust for Scotland conducted the first full survey in 24 years, finding a steep decline in the numbers of Fulmars, Guillemots, Razorbills and Kittiwakes. Kittiwakes were found to have fallen by 84%, Razorbills and Guillemots by more than 35%. Fulmar numbers dropped by over 45,000 on the islands. The dramatic declines are thought to be due in part to climate change and reductions of natural prey.

Conservation

Deforestation in the Amazon rainforest continues to decline according to Brazil’s National Space Research Institute (INPE). This marks the fifth consecutive month of decrease in deforestation in the region. The INPE’s deforestation alert system DETER showed that there was a 66% decline in forest clearing compared to the same month last year. The system has likewise shown a 43% decline in deforestation in the first eight months of 2023 when compared to the previous year. This follows commitments by Brazil’s president Lula da Silva to curtail the enormous forest losses seen over the past four years under the previous administration.

Author interview with Graham Tucker: Nature Conservation in Europe

This informative and wide-ranging book examines the nature conservation responses of the UK and twenty-five EU Member States, analysing their achievements and failures and providing notable case studies from which comparisons and lessons can be obtained. Covering topics such as biodiversity pressure, legislation and governance, biodiversity strategies, species protection, protected areas, habitat management and funding, the book provides an incredibly in-depth appraisal of our management of European ecosystems and species and how this has contributed to the current concerning state of nature in these regions.

Editor Graham Tucker is an ecologist and a leading authority on European nature conservation policy, with a particular interest in its achievements and failures. He currently works as an independent consultant and proprietor of Nature Conservation Consulting. Prior to this he worked for Birdlife International and as Head of the Biodiversity Programme for the Institute for European Environmental Policy.

We recently chatted with Graham about the book and about the necessity for international co-operation in conservation, the importance of funding, stakeholder engagement and societal support in the creation and maintenance of protected areas, plus his plans for the future.

This is an impressive endeavour into covering the enormous topic of conservation across Europe. What inspired you to create this book?

Several things drove me to prepare the book. Firstly, like many others, I am concerned by the ongoing decline in many species and degradation of habitats in Europe, and that nature conservation has not been able to halt, let alone reverse most losses. Whilst there have been successes for some species, they have been insufficient, and consequently biodiversity targets have been repeatedly missed. Secondly, having had the privilege to work over the last few decades with many nature conservation experts across Europe, I realised the reasons for these failures varied between countries. Whilst the broad approaches to nature conservation have been similar, there have been significant differences, especially in their implementation and outcomes. Comparing national experiences could therefore provide valuable lessons in terms of which nature conservation measures have, and have not worked, and why. However, nature conservationists have tended to mainly draw lessons from national experiences, in part because of language barriers and the other difficulties with finding relevant key information.

Therefore, there seemed to be a need for a book that describes and critically examines the nature conservation objectives and actions that have been taken in Europe, primarily through individual country chapters written by national experts with a deep knowledge of what has really happened. Having discussed the idea with some nature conservationists I found that there was considerable enthusiasm for the book and many willing to contribute, despite the huge amount of work it would involve. This was also inspiring and persuaded me to go ahead as its preparation has depended on the hard work, generosity and patience of many people; of which I am especially indebted to the 52 co-authors.

Chapter 3 discusses the international drivers of nature conservation and their impacts on policies in Europe. How important is international co-operation and coherency in policy to nature conservation? Do you think there is enough large-scale international conservation?

International cooperation and coherence are vital for effective nature conservation. This is most obviously the case for migratory species, as well as rivers, seas and ecosystems that cross national borders, and transboundary protected areas. This has been widely recognised, so there is now a reasonably complete nature conservation framework in Europe, including the global UN Convention on Biological Diversity (CBD), the Convention on the Conservation of European Wildlife and Natural Habitats (Bern Convention) and, of most influence, the legally binding EU Birds and Habitats Directives. These agreements have aided cooperation such as through sharing programmes of work, knowledge and funding. Most importantly, they have helped raise ambitions by creating a level playing field – which gives countries the confidence to act, knowing that they would not be alone.

Unfortunately, the UK’s departure from the EU has undermined this cooperation and alignment, resulting in potential divergence in ambitions, policies and legislation, both between the UK and EU and between the UK nations. So far there has been little divergence in UK practices and standards are being maintained. But this could change with time, especially in England as a result of the Retained EU Law Bill.

Chapter 5, ‘Conclusions, Lessons Learnt and Implications for the Future’, mentions that, while nature conservation has likely slowed the rate of decline, many habitats such as wetlands and semi-natural grasslands forests have continued to be lost or degraded. Do you think large-scale commitments such as the one to increase the UK’s and EU’s protected area network to 30% of both land and sea by 2030 will generate the right amount of funding, stakeholder engagement and societal support to create effective, large-scale conservation?

I am sure there is wide public support for the improvement and expansion of the protected area network, both on land and sea, in the UK and elsewhere in Europe. This is because the potential nature and wider related social and economic benefits of protected areas are increasingly appreciated. However, in most countries it is more important to improve the effectiveness of the existing network, in particular with stronger nature conservation objectives and better practical management. This requires more funding and stronger regulation, which I am doubtful that most governments are currently committed to.

This chapter also mentions that nature conservation is dependent on enforced legislation, funding and motivated people. Which do you believe is the hardest to obtain and therefore is the biggest threat to current and future conservation efforts?

All three are needed, and they are to some extent interrelated and dependent upon each other. However, the lack of funding, which is in part due to insufficiently motivated politicians, is currently the main constraint in most countries. This hampers the enforcement of legislation, as well as limiting practical nature conservation and restoration actions in protected areas and the wider environment.

Whilst public support for nature conservation is substantial in many countries, especially the UK, it varies greatly. Political support also tends to lag behind public support, in part due to the influence of powerful lobbying groups. Wider and deeper societal engagement is therefore essential to stimulate stronger political support, funding and regulations. It is therefore encouraging that support for nature conservation is growing. This is needed now to counter recent calls from some politicians in the UK and EU to weaken some environmental ambitions and slow down actions.

What impact do you hope that this book will have?

I hope that the book will clearly show that nature conservation works when it is properly implemented – such that it can halt biodiversity declines and even restore ecosystems. Therefore, the ongoing biodiversity crisis is not because we are doing the wrong thing. On the contrary, we need to massively scale up what we are doing already. As said, we know what we need: strong and enforced regulations, more and better targeted funding, and more deeply motivated people to call for and help conserve nature. We should still seek to improve the effectiveness of nature conservation measures, basing policy and practical decisions on evidence, but be wary of calls for radical changes in approach.

Of all the countries discussed within this book, which do you believe are leading the way in nature conservation?

Unfortunately, this is not easy to answer as it is often difficult to reliably compare data across the countries. For example, some countries have large protected area networks (e.g. Croatia, Slovakia and Slovenia) in contrast to others (e.g. Belgium, Finland, Ireland and Sweden). However, the statistics are not always reliable as some countries, such as Bulgaria, Denmark and UK include areas that do not meet internationally recognised protected area definitions. Furthermore, the effectiveness of protected area network is not necessarily closely related to their size, but more their conservation objectives and the effectiveness of their practical management. Similarly, comparing the adequacy of funding is difficult because needs vary and it is not always clear how much goes towards species and habitat conservation priorities, and what it actually achieves.

As described in some detail in the conclusion chapter, all countries have both strengths and weaknesses, so it is difficult to identify overall leaders. As regards the UK, we have been leaders in some respects in particular in relation to science and the strong role of NGOs, and producing a wealth of strategies, including the first Biodiversity Action Plan in the world in response to the CBD. However, the UK has underperformed overall, primarily due to poor implementation of its strategies and other initiatives, largely as a result of limited political support and therefore weak regulations and inadequate funding.

Do you have any future plans that you’re able to share with us?

As the book has taken over five years to prepare, I am having a bit of a break from writing for the moment. But I am continuing to work on EU and UK nature conservation issues, especially in relation to climate change.

The impacts of climate change on nature are of growing concern to me, as I think they will be much worse than many people realise. In addition to the increasing disruption to ecosystems, there is the likelihood of huge impacts from climate change mitigation measures and adaptation actions over the next 30 years. Whilst it is essential to reduce greenhouse gas emissions, many proposed responses can be highly damaging for nature, including widescale inappropriate afforestation, use of bioenergy, solar farms and hydro-energy. Damaging climate change adaptation measures are also likely to increase, such as increased water abstraction from wetlands, as is already affecting the Coto Donana in Spain. At the same time, well designed ecosystem-based measures can contribute substantially to mitigation and adaptation, whilst being beneficial for nature – but these are being underused. Maybe, in time, I will prepare a book on this.

Interview with Jan Collins: Bat Surveys for Professional Ecologists 4th Edition

Purple cover for Bat Surveys for Professional Ecologists with lots of images of bats.The 4th edition of Bat Surveys for Professional Ecologists: Good Practice Guidelines is the latest update of the Bat Conservation Trust (BCT) Guidelines and features new content on biosecurity, night-vision aids, tree surveys and auto-identification for bat sound analysis. Several key chapters have been expanded, and new tools, techniques and recommendations included. It is a key resource for professional ecologists carrying out surveys for development and planning.

Portrait image of the author Jan Collins

Jan Collins is the Head of Biodiversity at the Bat Conservation Trust and a former ecological consultant. Her fascination in bats began when participating in a bat biodiversity survey on a Vietnamese expedition in 1999 and she has worked in bat conservation ever since. She has been in her current role for the last 10 years and has played a central role in the editing and refining of the BCT Guidelines.

In this Q&A we had the opportunity to speak with Jan about some of the key aspects of the 4th edition of the BCT Guidelines and its consequences for ecologists.

What led you towards a career specialising in bats?

From a young age I was interested in being outdoors and engaging with nature. My studies followed this route, with a degree in Environmental Sciences and a Masters in Ecology and Management of the Natural Environment. I was first introduced to bats on a Frontier expedition to Vietnam in 1999 where we were trapping bats as part of a biodiversity survey. I was immediately hooked (what an amazing group of animals, with unique behaviours, and so very diverse!) and sought both voluntary and paid work involving bat conservation upon my return. I was an ecological consultant specialising in bats for over 10 years before joining Bat Conservation Trust in my dream job as Head of Biodiversity almost exactly 10 years ago now.

Could you tell us briefly about the work that the BCT does?

BCT is a dynamic, influential and growing national charity. We are the leading non-governmental organisation in the UK devoted solely to the conservation of bats and their environment. Our work represents the gold standard in bat conservation providing a lead for the rest of the world. We work to ensure that bat conservation is acknowledged as an integral part of sustainable development. Our work ranges from best practice guidance, advice and training through to engaging wider audiences so that we can get more people to understand the importance of bats and their conservation. A lot of our work also involves working with partners on the ground, local bat groups play a huge role in all aspects of our work. More information about all of our work can be found in the most recent annual review, found here or take a look at the Bat Conservation Trust Website here.

The 4th edition of Bat Surveys for Professional Ecologists: Good Practice Guidelines is due to be published in September 2023. What have been some of the key challenges in getting this ready for publication?

One of the key challenges for this edition was gaining consensus from the Technical Review Board on some of the recommendations. This included the continued use of transects for bat activity surveys and how tree surveys for bat roosts should be carried out, acknowledging the various limitations, and how approaches should be adapted to different types of projects. Another challenge has been how much to include on night vision aids such as infrared cameras. BCT are planning a kick-off meeting for a working group to develop separate night vision aid guidelines in the autumn (to include infrared and thermal imaging cameras) and therefore many aspects are still to be discussed and decided. We will also run a public consultation on night vision aids to help us to understand current practice and expectations from new guidelines on this topic.

How has the outlook for bat populations in the UK changed since the last edition of the Guidelines?

Data from the National Bat Monitoring Programme indicate that populations of the bat species we monitor in the UK are stable or recovering. However, it should be remembered that these trends reflect relatively recent changes in bat populations (since 1999 for most species). It is generally considered that prior to this there were significant historical declines in bat populations dating back to at least the start of the 20th century. This suggests that current legislation and conservation action to protect and conserve bats is being successful, and it is vitally important that this continues. Detailed information on trends for the 11 species monitored can be found in our National Bat Monitoring Programme reports here. We are also seeing signs of regional variations that deviate from the overall positive trend at the national level and we want to gain a better understanding of those. More data would help this process so we would encourage everyone to join in with one or more of the National Bat Monitoring Programme surveys. There are surveys that are suitable for anyone regardless of experience or equipment.

What are some of the key changes in the Guidelines?

A number of chapters have been expanded and new tools, techniques and recommended best practice incorporated. Below are a few of the changes but we will be developing a webinar in the coming months, detailing all of the changes so readers should watch out for that!

  • A new section on Biosecurity has been added to Considerations for Bat Surveys chapter, recognising that precautionary approaches are needed to protect both ecologists and bats from potential health risks.
  • Chapter 6 on Surveying Trees and Woodland for Bat Roosts has grown from five pages in the 3rd edition and now includes details of newer technologies and sources of information such as night vision aids, motion activated camera monitoring, The Bat Tree Habitat Key and the Bat Roost Tree Tag Project as well as updated guidelines for categorising the suitability of potential roost features.
  • Chapter 7 focuses solely on dusk emergence surveys, with dawn re-entry surveys removed as a standard approach due to the improved quality of emergence surveys with night vision aids and the variability in the time that bats return to their roosts.
  • Chapter 10 on Data analysis and Interpretation incorporates information on auto-identification systems and has a new section on data science which includes details on elements such as tidy data, minimal data requirement and data standardisation. There are also case studies to help illustrate key points.

How will the new Guidelines improve the way ecologists approach bat surveying?

The guidelines are the key resource for professional ecologists carrying out surveys for development and planning. The Biosecurity section in the 4th edition will ensure that ecologists carry out their work in a safe way, minimising health risks to both themselves and to bats. The latest edition acknowledges the constraints involved in surveying trees for bat roosts and offers different approaches to surveys depending on the nature, scale and timeline of the project. A new categorisation system for Potential Roost Features (PRFs) and trees reduces the subjectivity in initial assessments of trees. Dawn re-entry surveys are no longer recommended as there are questions around their efficacy for presence/absence and because emergence surveys can be vastly improved by the use of night vision aids. A stepwise approach is offered to those using auto-identification systems to analyse acoustic datasets and the section on Data Science aims to standardise approaches to data management. The guidelines also make reference to a wealth of resources that can be used to improve surveys and, in particular, interpretation of survey data.

Nocturnal survey equipment such as night vision, thermal imaging and infrared cameras are becoming more important in bat survey with the 2022 Interim Guidance Note providing clarification of their role. How will the 4th edition of the Guidelines impact the way ecologists conduct bat surveys using these types of equipment?

The 4th edition supercedes (but is consistent with) the Interim Guidance Note published in May 2022. It emphasises that surveys should usually be carried out with night vision aids and that if they are not used this should be justified in reporting, with reasons provided (e.g. at known roosts when bats are known to emerge early or in situations/locations with higher levels of natural or artificial light). Dawn re-entry surveys are no longer recommended as a standard approach because the use of night vision aids vastly improves the quality of emergence surveys, when used properly. The new guidelines state that a still shot must be taken at the darkest point of the survey to show the field of view and that appropriate illumination has been used. They suggest that the use of night vision aids can be used to reduce the number of surveyors but only if the cameras/lighting reliably match or exceed what a surveyor can achieve, with evidence provided. See the 4th edition for more information on use of this equipment!

BCT are planning a kick-off meeting for a working group to develop separate night vision aid guidelines (with much more detail) in the autumn (to include infrared and thermal imaging cameras) and therefore many aspects are still to be discussed and decided. We will also run a public consultation on night vision aids, to help us to understand current practice and expectations from new guidelines on this topic.

The Autumn 2023 issue of Conservation Land Management

The Autumn 2023 issue of Conservation Land Management (CLM), out soon, is filled with an informative mix of articles, including the management of conifers for saproxylic invertebrates as part of our Habitat Management for Invertebrates series; the advantages and disadvantages of wildflower seed sowing; assessing and mitigating the disease risk associated with conservation translocations; and the story of Lower Bridge Meadow and how it is managed today. Read on below for a more detailed summary of what you can expect to see in this issue.

The sowing of wildflower seeds has increased over the past few years, and we now often see colourful wildflower displays in urban greenspaces or along road verges. These mixtures, however, are often made up of non-native species, and so their value can be questioned by botanists and ecologists. Dr Kevin Walker, Head of Science at the BSBI, discusses some of the key issues related to wildflower seed sowing, and looks at the advantages and disadvantages that this can have for native plants and other wildlife.  

Approximately 129 species of beetle are associated with pine in Britain, 44 of which are specialist species of old-growth pine forests, but the ecology of saproxylic invertebrate assemblages associated with pine and other conifers remains poorly known. In the third article of the Habitat Management for Invertebrates series, Keith Alexander describes the features of conifer woodlands that are vital for saproxylic invertebrates, key considerations for landowners involved in managing areas with coniferous trees, and areas where new research is needed to improve our understanding of how to manage these habitats for dead-wood invertebrates. 

Conservation translocations refer to the movement of animals or plants from one location to another for the purposes of conservation. One important aspect to consider during translocation is the risk of disease; the movement of an animal also includes all the viruses, bacteria and parasites it may carry. Sophie Common and Tony Sainsbury, who are both involved with the Disease Risk Analysis and Health Surveillance project, part of the Institute of Zoology at the Zoological Society of London, describe the impact that introduction of a novel pathogen can have on a translocated animal itself and also on other wildlife, and provide some UK-based case studies, such as the treatment of tapeworm in Hazel Dormice and the screening of the pathogen Crithidia bombi in Short-haired Bumblebees prior to their reintroduction, to illustrate how the risk of disease is assessed and managed.

Bucklebury Common, in West Berkshire, is a 340ha stretch of land and the largest open heath in the county. Used as a truck depot in the Second World War, the common is now in part designated as a Local Wildlife Site for its heathland, veteran trees and woodland. The heath is an important habitat for rare birds such as Nightjars and Woodlark, and a necessary part of its management is to control colonisation by Silver Birch from surrounding secondary woodland to prevent it from dominating the heath. After several methods, such as weed-wiping and hand pulling, were attempted with mixed success, an excavator was brought to the site with three different attachments (a flail head, a root fork and a grab) to trial an effective and possibly novel technique for removing birch seedlings. In this article, Alex Cruickshank describes the success of the different methods that were tested, and outlines how management of Bucklebury Common might develop in future.

The final article in this issue focuses on a much smaller fragment of land. Lower Bridge Meadow is a 0.86ha Local Wildlife Site in Herefordshire, designated as such for its diversity of wildflowers. Interestingly, the meadow has a long-recorded land-use and management history, and here James Marsden and Helen Woodman describe both past and current approaches to management and speculate what the future may hold for this species-rich grassland. Lower Bridge Meadow is likely to be just one example out of hundreds of small sites that are set aside for the wildlife, but the failures and successes of their management are seldom shared among landowners. CLM is an ideal place to share these experiences – if you are managing a slice of land for wildlife, no matter how compact or inconsequential it might seem, we would love to hear about it. Feel free to get in touch with us to find out more about writing for CLM.

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, such as Review, which can include letters from readers or updates from our authors, also regularly appear in CLM. 

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. If you would like to read any of these articles, back issues are also available to purchase individually (subject to availability). 

 

Book reviews in volume 34 of British Wildlife 

Ever since the very first issue back in 1989, British Wildlife has featured book reviews of the most important new titles in natural history publishing, from nature-writing bestsellers to technical identification handbooks, and every review included in the magazine since 2018 is available to read on the British Wildlife website. These reviews provide in-depth critiques and are all authored by experts in relevant subjects, ensuring an honest and insightful appraisal of each book featured. Here is a list of the book reviews included in volume 34 of British Wildlife, all with links to take you directly to the full review.

  1. The genus Cortinarius in Britain by Geoffrey Kibby and Mario Tortelli

“This monograph has keys, descriptions and notes for every species, but its crowning glory is the pictures: coloured drawings by Geoffrey Kibby combined with colour photographs taken in situ by Mario Tortelli.” 

– Peter Marren, BW 34.1 October 2022. Read the review here. 

 

 

2. Land Healer: How Farming Can Save Britain’s Countryside by Jake Fiennes

“Fiennes is forthright, his arguments stocked with enough facts and figures to baffle all but the most diligent reader. Yet for me they convince because they resound with first-hand experience and learning…” 

– James Robertson, BW 34.1 October 2022. Read the review here. 

 

 

  1. Concise Flora of the British Isles by Clive Stace

“I cannot imagine anyone with more than a passing interest in the British flora not having this book, and I suspect that many may now rely on this much cheaper alternative as their British Flora of choice.” 

– Fred Rumsey, BW 34.1 October 2022. Read the review here. 

 

 

  1. Impacts of Human Population on Wildlife: A British Perspective by Trevor J. C. Beebee

“This is a well-written account by a very well-informed British naturalist of the way population affects wildlife. It is written without recourse to technical jargon, but also with a careful, precise and temperate use of language, and with the balanced judgements which you would expect in a small-circulation scientific series published by Cambridge University Press.”

Author interview with Arnold Cooke: Tadpole Hunter

In Tadpole Hunter, author and conservationist Arnold Cooke provides us with a personal and unique insight into the history of amphibian conservation and monitoring within Britain. As well as telling the story of amphibian natural history since the 1960s, it also provides a very human perspective on how we got to where we are today and how our knowledge of amphibian populations and dynamics has progressed over the second half of the 20th century. Packed with wonderful photographs along with charts and tables representing monitoring data, this accessible book will appeal to anyone interested in amphibians and the history of conservation in Britain.

Arnold Cooke was a researcher and advisor for the the Nature Conservancy and Natural Conservation Council for 30 years. Since leaving English Nature in the late 1990s he has continued to pursue his interests in amphibians, birds and deer and has published widely on subjects as diverse as the status of Britain’s amphibians and reptiles, pollutants in birds and the environmental impacts of introduced species of deer. His previous book, Muntjac and Water Deer, was published in 2019.

In this Q&A we chat with Arnold about his work with amphibians in the UK, the changes he has seen during his years working in conservation, and his hopes for the future of amphibian populations.

Although working with amphibians and their conservation has been a key part of your career, you have also dedicated a lot of your free time to recording and monitoring them and adding to the general body of knowledge regarding their populations. What is it about amphibians that you find so fascinating?

Amphibians have always appealed to me particularly because they can be relatively easy to catch – at least for vertebrates. However, they could be quite scarce where I grew up, and as a boy I was more interested in birds, flowers and invertebrates. When, in 1968, I joined the Nature Conservancy team studying the impacts of pesticides on wildlife, there were indications that frogs had declined, possibly because of pesticide use. An attraction of such a project was that there were significant gaps in knowledge about the natural history of frogs and other amphibians. This meant I had a fairly blank canvas at the beginning and I needed to undertake basic studies to try to understand what made frog populations tick, as well as doing pesticide studies. Later, I joined the Nature Conservancy Council, and became involved with conserving amphibian species nationally. By then I had started studying amphibians in a personal capacity, and was able to adapt or start local projects to inform issues of national interest, such as developing monitoring methods and investigating population stability and responses to impacts of various kinds. As information from these studies became available, it could be fed back into the system to conserve amphibians – and so helped me do my job more effectively. Once started, I became increasingly hooked and often found it difficult to stop the various strands of work.

You mention how, early in your career, you were faced with the challenge of discovering how populations of amphibians had changed in the distant and recent past and that, given the lack of empirical field data, sending questionnaires to suitable candidates was the best way to gather information about this. Do you think that conservation initiatives for amphibians are still limited by accurate population/distribution data?

When I started to work on the common frog more than 50 years ago, there was no hard information on how the national population had changed, but several well-informed individuals considered that declines had occurred. I felt I needed to be sure that there was a problem before doing too much work on pesticides and should find out whether, where and when decreases might have occurred. I targeted those people in the British Isles who had observed frogs (and common toads) in their local ponds and this resulted in information from several hundred sites. To increase cover I asked biology teachers in schools about changes in their local populations. The consensus was that there had been widespread decreases for both species during the 1950s and 1960s. This technique had obvious flaws, but its overall conclusion seems broadly accepted. However, it is wise to acknowledge the drawbacks of the method and not to place too much credence on the resulting information, especially on reasons that might be offered for change. Where ponds were destroyed (or created) in an area, then there are tangible reasons for change. However, this is often not true for suggested contributions such as from collection, road mortality or, indeed, pesticides. Because of the population dynamics of amphibians, substantial changes occur naturally and loss of some individuals does not necessarily translate into population decline.

During later decades of the twentieth century, several similar studies were undertaken, but since the turn of the century an attempt has been made to set up a statistically sound monitoring system for the widespread amphibians and reptiles. Unfortunately, number of sites covered initially was insufficient to provide a completely satisfactory basis for the scheme to go forward in that form. Consequently some modifications and compromises were needed, and a new approach has now started. Progress is being made employing novel field, laboratory and computer methods. And I am hopeful that herpetologists can continue to tap into citizen science projects on other animal groups, particularly birds, where huge numbers of competent individuals might be organised to gather additional data on amphibians.

I should also say that knowledge of the much rarer natterjack toad is exceptionally good. All known colonies are recorded regularly, and some have been monitored continuously for 50 years. This has allowed fine tuning of conservation action at specific sites and more broadly. And the very rare pool frog receives constant attention at its introduction sites.

As someone that worked at the forefront of conservation for many decades and has seen a huge number of changes, both in the natural world and in the human organisations and councils that are charged with protecting them, are you broadly hopeful for the future of British wildlife?

Thank you for the compliment, but I’m not sure how long I’ve spent at the ‘forefront of conservation’ – especially during the last 25 years when I’ve deliberately busied and buried myself in the detail of my own interests. Throughout my life, I’ve worked as a specialist in a range of disparate areas, rather than as a rounded generalist, so I’ve tended to focus on specific issues within the broad spectrum of wildlife conservation.

It’s true, however, that I’ve seen huge changes over the last 55 years. Some changes are of great concern – no one 50 years ago saw global warming coming. I remember there was talk about 40 years ago of the possibility of another ice age being just round the corner. The changes in biodiversity over that time have of course mainly been losses. On the other hand, there have been other types of change providing hope that British wildlife does have a reasonable future. I am thinking, for instance, of the numbers of professional people and volunteers now involved in conservation, the knowledge that has accrued, the conservation methods that have been shown to work and the legislation that has been passed. I’m aware that successive governments haven’t necessarily dealt kindly with environmental issues (or conservationists), but many peoples’ attitudes have changed markedly and younger generations are especially concerned about the environment. Just as conservationists in the past achieved more than might be expected because of their dedication, so should conservationists of the future – and there will be many more of them.

The wildlife communities and their distribution will, though, probably look very different in the future. I have lived for 55 years on the edge of the Cambridgeshire Fens. That area doesn’t sound very promising for wildlife, but I was pleasantly surprised to discover in 1968 that there were several nature reserves within easy reach including three important National Nature Reserves. However, I soon realised that reserves were like currants in a cake, there being very little of interest between them. When my wife and I drove to Norfolk to visit three other NNRs, we only managed to find one of them, despite knowing their grid references – and we had to negotiate a barbed wire fence to get into that. A permit was required for access in those days. The situation is of course very different now: visitors are generally welcomed. And reserves are increasingly being connected up, as is occurring in my area with two of the NNRs. I don’t doubt that much of our biodiversity will in future be experienced inside landscape-sized areas. I just hope it works. I regret that kids today don’t have the freedom that I had to explore and find things out for myself. Presumably, however, accessibility of knowledge will continue to increase. No need for children to learn and remember much, just use the phone app. Not wishing to be too cynical, surely enough youngsters will be captivated to become the dedicated conservationists of the future?

As regards amphibians, I believe we have more or less stopped the declines of the twentieth century and recoveries have started for some species. The future is uncertain but there are reasons to be hopeful.

Your working life has been incredibly fascinating and varied. Are there any parts of it that you remember with particular fondness or that stand out in your memory?

I’ve been very lucky with what I’ve been allowed or managed to do during my working life of more than 60 years – that’s using the word ‘working’ very loosely. I still have a reasonably good grasp of what I did and when I did it because I’ve usually written up (but not necessarily published) my observations and thoughts in some form or other. When I’ve been able to study wildlife, there has been very little that I haven’t enjoyed. There have been stand-out moments such as: in 1962 when I found my observations demonstrated that birds in suburbia were more approachable than those in the countryside; in 1982 when I watched breeding newts by torchlight for the first time; and in 1994 when I realised I could put out tempting vegetation for muntjac in a wood and find it had been consumed by the following morning. Each of these moments led to the development of field monitoring techniques.

Then there have also been periods that have been memorable for different reasons. The five years 1968-1973 with the old Nature Conservancy at Monks Wood were marked by an extraordinary level of interest in our work shown by the public, politicians and even royalty. In contrast, the last couple of decades have been spent quietly at home pottering around doing as much fieldwork as possible and sorting out what results meant. My qualifications are in chemistry and biochemistry and, had things turned out differently, I might have been more of a lab worker. But working outside has always been my preference. When working for English Nature in the 1990s, we were required to fill in risk assessment forms when away from the office, including when working outside normal office hours. Some years, I filled in nearly 200 such forms, revealing how much fieldwork I did as well as providing an illustration of why I was glad to leave behind modern management methods in the late 1990s.

What would be the main message you would give to the conservationists and ecologists that are following in your footsteps?

Because of my rather blinkered working experience during the current century, I think the most appropriate message is simply to say, ‘good luck and thank you’. Everyone needs some luck in order to have a satisfying career and I genuinely appreciate what present and future generations are doing and will continue to do to help understand and conserve wildlife.

Finally, what is occupying your time at the moment? Do you have plans for further books?

My main task this year has probably been seeing Tadpole Hunter to fruition, so it’s good to have it published at last. I’d wanted to review some of the topics in the book for many years, but they’ve only appeared in book form because of the Covid pandemic. My wife and I needed to shield during the lockdowns, so I started to review a couple of subject areas in March 2020. Later that summer, I realised that I had the basis for a book, so roughed it out and continued writing. I don’t intend writing another book, in part because of the time commitment. While writing Tadpole Hunter, I published several items on deer and have vague plans for other articles once the dust has settled from the book.

I have occasionally tinkered with bird behaviour in a very simple way and may revisit data collected in the 1980s. Earlier this year, I was surprised and very pleased to be invited to contribute my historic data to a global database of avian ‘flight initiation distances’, which precipitated a dive into material I hadn’t looked at for many years. Another line I might pursue concerns citizen science. I’ve participated in a number of such projects over the years, recording birds in particular, but also mammals and trees. At the moment, I’m interested in what an individual participant could get out of it? If repeated annually, it can provide useful monitoring information on species at your location. In some instances, I have carried on recording for long after the citizen science project finished.

Although I’m now doing very little fieldwork, I still have ideas to explore, but I’m sure there won’t be another book unless……….

Science and Research

Mountain treelines are ascending due to climate change. Scientists at the Southern University of Science and Technology in Shenzhen, China, used remote sensing technology to analyse mountain tree cover. The results show that 70% of mountain treelines moved upwards during the period between 2000 and 2010. Trees are moving fastest in the tropical regions at an average of 3.1 meters a year; the movement is accelerating with time. The changes in tree distribution could be catastrophic for some species. Alpine species are especially at risk of being crowded out by the treeline moving uphill.

Climate crisis

Earthquake and rare tropical storm Hilary strike southern California at the same time. The storm brought rains of 10 to 12cm and caused power outages, flooding and mudslides across the region. Southern California, which usually experiences persistent drought, is vulnerable to rainstorms. Flash floods and mudslides hit the region while a 5.1 magnitude earthquake struck near Oxnard north of Los Angles. No immediate reports of damage were reported.

Canada deploys its military forces to tackle extreme wildfires in British Columbia. 35,000 people have been evacuated in the western province in what has been described as a “extraordinarily serious situation” by the country’s Prime Minister Justin Trudeau. Fires are also raging in Canada’s Northwest Territories with its capital city, Yellowknife, under threat and having been evacuated. The world has seen an unprecedented summer of wildfires with sweeping fires in Hawaii and the Mediterranean, prompting calls for action on the climate crisis.

Conservation

Ecuadorians have voted against oil extraction in Yasuní National Park in a nationwide referendum. 5.2 million people voted to prevent further drilling of crude oil in the National Park with 3.6 million voting against. Excavations have been underway since 2016 with 57,000 barrels of oil being produced per day. The protected area is home to a delicate rainforest ecosystem and indigenous communities. Oil spills, road construction and drilling provoked a fierce response from many indigenous and environmental groups culminating in the recent referendum victory. State oil company Petroecuador now has one year to withdraw from the region. Advocates for the drilling including some indigenous communities have argued that stopping the drilling will arrest development in the region and deprive the country of $1.2 billion in revenue.

Mexico announces the creation of 13 new protected areas with three more expected to be declared by the end of the month. The six new national parks and seven protected areas cover 17,918 hectares ranging from the Mexican states of Baja California and Baja California Sur to Oaxaca and Guerrero. The new additions bring the total number of federally protected areas in Mexico to 200.

Kielder conservation efforts see 11 young ospreys fledging this year. The Kielder Osprey Project in Northumberland National Park has helped 114 osprey chicks take their inaugural flights in 15 years. The success comes after ospreys were extinct in England for most of the 20th century. The recently fledged chicks will practice their hunting and flying skills over the next few weeks as they build up body fat reserves before they begin a 3,000-mile migration to Africa for the winter.

Extinction risk

Reports of bee-killing Asian hornets have risen to their highest point yet in the UK. The invasive hornet kills and dismembers its prey and presents a significant threat to native UK bee species. The hornet species first arrived in Europe in 2004 and has since caused havoc in France where they have devastated national honeybee populations. The Department for Environment, Food and Rural Affairs (Defra) in the UK has launched an eradication program in response to sightings in the UK. Once the hornets have become established, they are nearly impossible to eliminate. Some success has been seen in the Channel Islands where an army of volunteers are working to counter the hornets, employing techniques like triangulation and tiny radio tags to find and destroy hornet nests. However, there are doubts about how effective this action would be over a much larger area like that of the UK. A total of 39 have been spotted in the UK with 16 of those sightings occurring this year including locations as far north as Newcastle upon Tyne.

A tiny river fly has been brought back from the brink after a successful breeding scheme. The critically endangered insect, the scarce yellow sally, is a type of stone fly that was thought to have become extinct in the UK decades ago. However, after several of the flies were discovered in the River Dee, a successful breeding programme was launched at Chester Zoo. Scientists plan to release the tiny insect in the future, but concerns remain about the health of Britain’s rivers. The tiny stonefly requires pristine conditions to survive, however, only a small percentage of Britain’s waterways are considered to be at Good Ecological Status within the Water Framework Directive.

European Botanical and Horticultural Libraries Group (EBHL) Annual Conference

From Tuesday June 20th to Friday June 23rd, NHBS attended the business meeting of the European Botanical and Horticultural Libraries Group, or EBHL for short. This annual conference brings together librarians from academic libraries and herbaria for several days of talks and behind-the-scenes tours. For NHBS, this is always a valuable occasion to meet and speak to some of our key customers in person, both from Europe and the USA. This year, the meeting took place in London and was co-organised by four institutes: The Natural History Museum, London; The Royal Botanic Gardens, Kew; The Linnean Society of London, and The Royal Horticultural Society. So, what happens at such a meeting?

A Wardian Case on display at Chelsea Physic Garden

This year’s theme was “plant humanities”, resulting in an eclectic mixture of talks from, not just librarians, but also historians and arts and humanities scholars. For example, medieval historian Isabel Davis talked about digitisation of collections and the drawbacks and advantages that come with dealing with scanned documents rather than the originals. Mark Nesbitt and Kiri Ross Jones both related the experience of Kew in developing an interdisciplinary research programme with external partners in fields outside of botany. A recurrent theme in several of these talks was how botanical gardens are dealing with their origin and history as colonial institutes, and the legacy of their collections that have been built with objects taken from other countries. Given today’s discussions and debates around decolonisation, this is, understandably, a topic that requires serious attention, and humanities scholars and historians can often bring new perspectives and ideas to the table. Palace of Palms author Kate Teltscher, for example, spoke about a new project she is working on that will reexamine the history of Kew, which might just result in another book.

The Royal Botanic Garden, Kew now has a permanent treetop walk in its garden offering stunning views across London.

This conference also saw a break-out session, chaired by Dr Anna Svensson from Uppsala University, on a topic of particular interest to archivists: the presence of pressed plants, or traces thereof, inserted in old books. She is studying these as part of a three-year research project to identify why people did this, how it relates to the development of early bound herbaria (books known as horti sicci, the plural of hortus siccus), and what conservation challenges they pose for archivists and librarians.

The Linnean Society has a rare collection of documents and books that belonged to Karl Linnaeus, including early editions of his works that he annotated while developing his system of biological nomenclature.

Alongside this busy programme of talks, during the afternoons the organisers had arranged behind-the-scenes tours around parts of the collections of all four institutes that are normally not accessible to the public. As such, on Tuesday I was able to marvel at Sir Hans Sloane’s collection of bound herbarium books that are held at the NHM in London. Not only did he put together some of these himself, later in life he bought or inherited collections of other people, resulting in over 200 large volumes with pressed plants from around the world. In the evening, I stood right next to a Wardian case during a tour of the Chelsea Physic Garden. Wednesday I admired some remarkable archival material at Kew (and enjoyed their treetop walk), while on Thursday I marvelled at the large collection of original manuscripts and books from Carl Linnaeus that are held in the basement room of the Linnean Society. This included a copy of an early edition of the Systema Naturae that has his handwritten annotations all over the margins. Friday the whole group took a coach to RHS Wisley, just outside of London, where we toured both the original research buildings and the brand-new library and herbarium of this remarkable horticultural institute.

The new library at RHS Wisley has been awarded several prizes for its architecture and offers views into the garden throughout the building.

We would like to thank the organisers of this year’s conference, in particular Isabelle Charmantier and Will Beharrell who headed it all up. NHBS is looking forward to next year’s meeting and welcomes opportunities to develop closer ties with some of the professional and amateur organisations that we count amongst our customers, whether through attendance or sponsorship. Do not hesitate to reach out to us.

Author interview with Mark Avery: Reflections

cover for the book reflections with hillsides covered with animals and flowersReflections is a passionate commentary on the state of nature and conservation in the UK. In it, Dr Mark Avery explores the current condition of wildlife, why wildlife conservation is failing and what can be done to reverse its plight. He examines the role NGOs, land owners and government have in its failure, and crucially examples of successes too. Reflections is a valuable resource for those wondering what exactly is going wrong in nature conservation and what action can be taken to remedy this.

Picture of mark avery

Mark Avery is an author, blogger and former director of conservation at the RSPB where he worked for 25 years. His previous works include Inglorious where he examines grouse shooting in the British uplands, and Remarkable Birds, a compendium showcasing the extraordinary wonders of the birds that share our world. We had the opportunity to speak to Mark about how he came to write Reflections and some of the key themes from the book.

Could you tell us about how you came to write Reflections?

I guess there are at least three reasons for writing a book. First, that you have a great imagination and can tell scintillating stories. Well, that’s not me and I write non-fiction, though I have wondered about a fictional book about nature conservation and nature conservationists. Second, you have some amazing experiences that you want to share with the world. That’s not me either. Third, you think you have ideas about the world that will be useful to others, and that’s the category that Reflections is in. I have worked in wildlife conservation for over three and a half decades and so I’ve lived the issues about which I write, but I’m not writing about my experiences, I’m writing about my thoughts, ideas and take on the world. Those ideas were bubbling up so much that I thought I’d write them down. It felt a bit like a pressure valve being released. The good thing from my point of view is that it seems that lots of other people relate to my thoughts. That’s thrilling for any author.

How do you think people’s attitudes towards, and awareness of wildlife have changed in your lifetime?

I was a teenager 50 years ago so looking back to then, animal welfare concerns, which aren’t quite the same as conservation concerns but are mixed together in all of our heads, have grown enormously. That affects how people think of field ‘sports’, predator control, snaring etc. I welcome many of those changes in attitude. Climate change has come along and dominates, rightly, the environment scene, and that has implications for wildlife conservation. I sometimes think that nature conservation is a bit squeezed between welfare issues and hard environmental ones. But over that period conservationists have moved from playing in small nature reserves and chasing people persecuting wildlife, to a greater force having some influence (not enough!) on big public policies such as farming, forestry and fisheries. We need to develop more strength in those political realms if we are to see nature recover.

You talk in Reflections about situations where considerable gains in wildlife conservation can be obtained in exchange for small losses in profit from land use activities. How do you think land managers can be convinced to take the hit to their profits for the benefit of wildlife?

With respect, I don’t accept the premise of the question. It is utterly pointless to try to get a vested interest like agriculture (house building, private forestry, shooting etc.) to act for the public good. Our wildlife conservation bodies are too timid and nice to realise that is a dead end. One has to jump over the heads of such industry representatives and persuade the decision-makers directly to implement public policies that deliver public goods. Focus effort on the decision-makers!

In the book you frequently mention the trade-offs between the state of wildlife in the UK and living standards. How do you think we can we balance the need for government investment in wildlife conservation and in critical public services like the NHS?

I’m glad you noticed that – we live in a complex human world and most people don’t give a stuff about wildlife. The partial answer to that question is that spending on wildlife conservation is tiny – that’s why it doesn’t work very well. It could increase many times over and still be tiny compared with other expenditures. It would be a false dichotomy to say we can have either a thriving wildlife or a thriving NHS, but I concede at the moment neither is thriving. Another partial answer is that governments should use more regulation (‘thou shalt not’s) rather than spending money on persuasion. They are cheap for the public purse. And of course, there are real benefits, that have economic valuations, in having wildlife-rich landscapes that flood less (or less damagingly), store more carbon and make people happier. But it’s a big subject. Give me a list of government spending across departments and I’ll cross a few things out (I might start with nuclear warheads) but your list would be different from mine, I guess.

You mention that the number of people actively interested in wildlife conservation is relatively small. How can we get more people to care about wildlife in the UK?

This is what our wildlife NGOs would call recruitment, or growing their memberships. The trouble is, it’s easier to recruit members than committed members interested in nature conservation. The National Trust’s five million members are arguably a weaker force for good that Wild Justice’s zero members but 35,000+ newsletter readers (but I’m maybe biased there). I think we could get more nature conservation done, particularly more impact on government policies, by getting existing members more mobilised than we could by getting more members. We have a small army of devoted conservationists – it’s just that they aren’t well armed with facts and tasks. Having more badly equipped troops isn’t a great recipe for success, I feel.

Do you think it is likely that we will see an improvement in the state of wildlife in the UK?

I can’t say that it is likely but it is certainly possible – but impossible with business as usual. We, and this means our largest wildlife charities, need to get much better at influencing land use policies. That’s entirely feasible but needs a change of mindset. I hope Reflections will encourage that change of mindset.

Do you have any plans for further books that you can tell us about?

I always have ideas, I have two at the moment, but sometimes they come to nought, so I’m not telling! Watch this space!
