Conservation

Wildcats are thriving in a Scottish Highlands conservation project with only one death. Nineteen of the cats were released into the wild in the Cairngorms National Park in the summer. Thirteen new kittens that have been bred for the scheme will be released into the wild next summer. Wildcats are one of the rarest and most endangered mammals in the UK. They live in moorland and grassland where they feed on small mammals and ground-nesting birds. Interbreeding with the domestic cat has eroded the wildcat’s genetic diversity. They also face threats from feline disease, road collisions and fragmentation of their habitat. A concerted effort by the Saving Wildcats project which brings together the expertise and skills of a range of national and international organisations provides a glimmer of hope for the species in Scotland.

David Attenborough’s Planet Earth III is both horrifying and awe-inspiring, critics have said. The opening episode of the third instalment of the highly acclaimed nature documentary series was viewed by 5.6 million people and has been described as “visually stunning” and “majestic”. The latest series of Planet Earth has a notably darker mood than its predecessors, focusing on animals fighting for survival in the face of constant environmental change.

Discoveries

The mysterious death of 385 elephants in Botswana and Zimbabwe in 2020 was caused by a little-known bacterium, scientists have revealed. Elephants were found walking in circles before suddenly dying by collapsing on their faces in Botswana’s Okavango Delta and north-western Zimbabwe. Tests on the elephants have now shown that the cause was a bacterium called Pasteurella. The bacterium can result in septicaemia under certain conditions and has been linked to the sudden death of around 200,000 saiga antelopes in Kazakhstan.

Climate crisis

Increased melting of the West Antarctic Ice Sheet is unavoidable, according to new research. Scientists ran simulations and found that even under best-case emission scenarios, melting would increase three times faster than during the 20th century. The West Antarctic Ice Sheet holds enough ice to increase global sea levels by up to five meters. Significant sea level rises will be catastrophic for the millions of people living in coastal and low-lying areas.

The Greenland Ice Sheet could experience runaway melting if climate targets are not met. A study in Nature has suggested that the ice sheet’s melting will accelerate significantly if average global temperatures surpass a threshold of 2.3 C above pre-industrial levels. However, the scientists stress that action in the future could reduce ice loss even if the threshold is crossed. They argue that it is cheaper and easier to take action now rather than clawing back towards lower global temperatures later.

Atlantic hurricanes are more quickly strengthening from weak storms due to climate change. Scientists have said that human-caused climate change is creating the conditions that lead to a quick intensification of storms. Hurricanes are fueled by high ocean surface temperatures which have been increasing in recent years as the world’s oceans have absorbed over 90 percent of the excess warming from fossil fuel emissions. This presents a challenge for coastal communities as forecasting becomes more difficult the quicker a storm intensifies.

Policy

Countries are deadlocked over a “loss and damage” fund before COP28. The fund was agreed last year at COP27 in Egypt and is designed to help countries recover and rebuild from damage due to climate change. Developing and developed countries are at odds about which organisation should oversee the fund, which countries should pay and who will be eligible to receive funding. Developed countries back the World Bank as the host of the fund; however, developing countries argue that this would give donor countries too much influence over the fund. Talks stalled recently in Aswan, Egypt and the committee responsible for designing the fund will meet again on November 3rd and 4th before the COP28 summit begins later in the month.

£1 billion electric vehicle fund remains unallocated three years after it was first announced. The fund was first announced in March 2020 prior to the first Covid lockdown. The fund was intended to be used to support electrical capacity at service stations to allow for rapid charging of electric vehicles. While 96% of motorway services already have charging stations, increased use of electric vehicles means that there will be a demand for more charging capacity.

Extreme heat from climate change may make parts of the Earth uninhabitable. An interdisciplinary team of researchers from the Penn State College of Health and Human Development, Purdue Institute for a Sustainable Future and Purdue University College of Sciences modelled global temperature increases from 1.5°C to 4°C – a worst-case scenario. They found that a further increase of around 1°C would mean that 2.2 billion people would experience many hours of heat that surpass human tolerance thresholds. It would be particularly concerning for residents of high-humidity areas where heatwaves would be considerably more dangerous for human health.

Whales and dolphins in the US are losing food and habitat to climate change, according to a new study. Researchers from the National Oceanic and Atmospheric Administration found that over 70% of American marine mammal species stocks are vulnerable to threats associated with warming waters. This includes shrinking food and habitat availability, changes to ocean chemistry and reduced dissolved oxygen levels. Large whales such as North Atlantic Right Whales and Humpbacks are most at risk from the effects of climate change. This comes on top of new research published in Nature Climate Change that suggests that marine heatwaves are infiltrating deeper parts of the ocean, the consequences of which could have widespread impacts on marine ecosystems.

Conservation 

Beavers have been reintroduced to west London for the first time in 400 years. The release of a family of five Eurasian Beavers to wetlands in Ealing comes as part of a push to improve biodiversity and mitigate the impact of climate change. There had been plans to spend money on flood prevention measures in the area but beavers were considered to be a more cost-effective natural solution. 

Canada rejects pleas from environmental groups to protect endangered owl habitat. One wild-born owl remains in British Columbia where logging has severely impacted the species’ old-growth forest habitat. The decision means that the future of the species is uncertain. The rejection of an emergency order for the protection of the owl comes after an eight-month delay since the environment ministry was required by law to recommend an emergency order under the Species at Risk Act. Environmental groups have responded with legal action following the delay. Biologists advise that the species could recover with adequate protection of old-growth forest habitat. 

Extinction Risk 

Almost half of flowering plants could be threatened by extinction, scientists have warned. Researchers analysed data from the World Checklist of Vascular Plants, the world’s most comprehensive database of plants available, and the International Union for Conservation of Nature’s Red List of Threatened Species and found that 45% may be at risk of extinction. Other key findings suggest that 77% of the 19,000 new plants and fungi species discovered since 2020 are endangered and that only 10% of an astounding 2.5 million species of fungi have been discovered.

Similar numbers of male and female sea turtles give hope for the survival of the species. Papua New Guinea’s Conflict Group’s analysis of turtle hatchings between 1960 and 2019 showed that an average of 46.2% have been female. Sea turtles are susceptible to rising temperatures due to their sex determination being temperature dependent. Scientists suggest the results are “likely rare in the global context” with sand temperatures having risen by 0.6°C over the same period. Another study of Green Sea Turtles from the same latitude showed that more than 99% of hatchlings were female, spelling decimation for the population.

Discoveries 

A small West African crocodile can moo like a cow, audio recordings reveal. Scientists use audio recordings to monitor elusive crocodile species which are difficult to confirm via visual surveys. The tiny African Dwarf Crocodile (Osteolaemus tetraspis) inhabits the swampy forests of West Africa. Scientists believe that the crocodile is quite common given its common occurrence in the bushmeat trade. Consequently, they are using audio recordings to listen out for its calls and have discovered that the crocodile, surprisingly, moos like a cow.

Animals fear the sound of a human voice more than that of a lion, according to researchers. A study in South Africa’s Kruger National Park found that, when playing recordings of human voices, 95% of animals were extremely frightened and ran away. Snarling and growling lion recordings provoked significantly less alarm among the wild mammals. The response to the recordings, which included human speech from local languages, suggests that animals have learnt that contact with humans is lethal. Researchers have noted that this may present a challenge for areas relying on wildlife tourism, as visitors can inadvertently scare away animals. 

Supplier interview with Faunus Nature Creations

Faunus Nature Creations is an ecological design agency established in 2018 as a subsidiary of NatuurInclusief. They focus on designing, building and selling fauna facilities to create nature-inclusive urban living environments and are widely recognised for their creative nest boxes. Most of their products are made in-house and they work closely with their suppliers and partners to ensure both functionality and beautiful design.

We had the opportunity to speak with Jarno Beijk, the founder of Faunus Nature Creations, about the company, their range of nest boxes and plans for the future.

What inspired the creation of Faunus Nature Creations?

Faunus General Purpose Bat Box.

Faunus Nature Creations (FNC) was founded in 2018 as a business unit part of ecological consulting agency NatuurInclusief.  At NatuurInclusief we regularly had to deal with mitigation projects as compensation for bat roosts getting disturbed. During field checks of these bat boxes, we discovered that the quality of the materials used were rapidly deteriorating. They did not meet any of the quality requirements and longevity that we wanted and expected from the bat boxes. From this moment the only solution we saw was to roll up our sleeves and design and build better nest boxes ourselves. Currently we are doing this with a team of ecologists, designers, engineers and architects. 

Could you tell us about the range of boxes produced by Faunus and which animals they are suitable for?  

In the beginning, our main focus was on roost boxes for bats, and nest boxes for House Sparrows and Swifts. The reason behind this choice is because they are the most strictly protected species by law. Fortunately, there is increasing awareness of building and designing in a more nature-inclusive manner, which means that there is increasing interest in nest boxes for other species as well. This includes species such as Kestrels, Storks, insects, and ground dwelling mammals etc.

Pino built-in swift box.

Many of the boxes you offer are made from wood concrete. Could you tell us some of the benefits of using this material, both for the user and for the animal?  

All our fauna facilities are designed with the needs and requirements of the species in mind. Wood concrete has a long lifespan, also the hydrothermal modified wood that we use has a lifespan of more than 20 years. It is therefore mainly down to the preference of the user.

Wooden facilities are not suitable as a build-in option. For this, the better choice is going for wood concrete or even better for a ceramic option. The latter have the longest longevity. 

A great disadvantage of using wood-concrete and ceramics is that they do not lend themselves well for custom work. Therefore, wood is a very good option for custom work. That is why we make custom wooden bat boxes on request in all kinds of shapes and sizes. When customisation is required to be built-in, we make these on the basis of a cement board. 

Personally, we think wood is the most beautiful for external use, because it looks more natural, but other people appreciate the concrete look as well. You will not easily find plywood in our collection, because we find this material is insufficiently durable and has too short of a lifespan. 

Many of my colleagues have taken a liking to the names of your boxes, for example, Elisa and Gabriella. How do you decide these names?

Elisa and Gabriella bat boxes.

Every nest box or new design we develop and offer is a new family member to our collection. Each design therefore deserves a unique name and not just a code or number. The intention was to use the names of people in our team first, but some found it quite embarrassing if they had to promote a nest box that would bear their own name. We have therefore given the names a slightly Spanish twist. So, Roos became Rosita and Eva became Evita. Spanish names also sound more swinging than Dutch names. At the moment we have more models than employees, so we have now arrived at names of relatives, neighbours and friends. Our latest model nest box Milo is named after the newborn son of our colleague Roos. Furthermore, the mammal nest boxes have female names, and the bird nest boxes have male names.

Have you found that environmental regulations have had an impact on the boxes you sell? 

In the Netherlands we have a quite strict Nature Conservation Act. Our authorities require many strict mitigation standards concerning fauna facilities, for example in the form of bat roost boxes and nest boxes. This is a major reason that many of our clients need to buy the products we make. We ourselves are not in favour of this strict legislation, because people will lack intrinsic motivation to do something good for biodiversity in the end. We ourselves believe that you can achieve more for biodiversity if you know how to make people aware and enthusiastic to do something positive for biodiversity. Legislation of this mitigation standards leads to “must do”, enthusiasm leads to “wanting to do”.

What can you tell us about plans for new products in the future? 

Faunus Nature Creations does more than just develop fauna facilities. Of course, we will bring new and improved models to the market, but we also design many large custom facilities for biodiversity, such as designing and building bat towers. We noticed that there is a great need for this as well. Governments and project developers would like to show off that they are doing something great and important to boost biodiversity and they would like to have the label extravagant for that too. We think it’s a sport to combine functionality, quality and aesthetics. Our motto is not without reason: Building for Biodiversity. Let’s create something valuable!

Conservation volunteering with Wild Planet Trust’s Seagrass Project

I recently had the opportunity to witness first hand a team from the Wild Planet Trust working to survey seagrass meadows in the Torbay area. The ‘Save Our Seagrass’ project, which has been going for some years, involves repeated survey work throughout the year to assess the meadows’ health and the diversity of marine life that they support.  Having lost over 90% of seagrass meadows around the UK in recent centuries, these surveys provide vital information about the growth or decline of existing meadows, as well as potential impacts from factors such as global warming.

Megan and her team of volunteer divers met with me early on a Saturday morning to travel out into the bay to survey three specific meadows: Fishcombe Cove, Torre Abbey and Breakwater Beach. Each of these meadows carry unique characteristics derived from their locations. Torre Abbey is situated close to the harbour entrance of Torquay and is very shallow during low tides. The Breakwater Beach area is home to local swimmers and tourists.

The third site, Fishcombe Cove, near the fishing town of Brixham, holds a key to solving one of the problems that has contributed to the deterioration of the meadows. There are typically many reasons why a meadow sustains damage and/or gets wiped out, the most obvious being where fishing nets are trawled across the seabed. But more and more these days, casual leisure boat users cause damage by dropping their anchors. When damage occurs, it can take ten years or more to recover, assuming that the conditions are favourable.

An innovative approach to solving this problem has been using the deployment of “no anchor” buoys such as those that are situated in Fishcombe Cove. Designed to allow up to three boats to moor without dropping anchor, these buoys are chained to the seabed and have smaller submerged buoys attached to them which keep the chain from scraping the seabed and damaging the seagrass.

The surveys such as the one I observed use two different methods: a transect and a spiral form, and each dive team is equipped with a float with a GPS unit that stays on the surface and records their location as they move through and around the seagrass meadows. Each diver carries two hours’ worth of oxygen to be able to carry out the surveys at anywhere up to ten meters depth.  With underwater cameras they record the general health of the area and any unusual sightings along with expected marine life.

One of the observations from the divers from the surveys that I attended was the extent of life that had grown on the chains for the buoys, along with shoals of Bib (Trisopterus luscus) that were using the seagrass for cover. Around the meadow near Torre Abbey, plenty of additional life was found including Pipefish (Nerophis ophidion), Common Cuttlefish eggs (Sepia officinalis), Hermit Crabs (Pagurus bernhardus), gobies, periwinkles and Sea Slaters (Ligia oceanica).

All the data from the dives will be collated and, following a single additional dive day schedule in October, the team at the Wild Planet Trust will start the process of analysing the collected date from this year, looking at how the meadows have changed in comparison to previous years.

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.

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.

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.

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.

This Week in Biodiversity News – 28th August 2023

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.

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!
