Interview with RSPB: A Night of Nature

In a first for Europe’s largest conservation charity, the RSPB (Royal Society for the Protection of Birds) is bringing the spectacle of the natural world to the big screen. Coming to London’s Troxy on 6th September, ‘A Night of Nature’ will blend cinema with the immediacy of a concert, thanks to live music synched to stunning footage of natural habitats and species, performed by string quartet Vesper and multi-million selling vocal group G4.

Ahead of the event, NHBS colleague Laura had a chat with Emma Marsh, the Executive Director for Digital Technology and Communications for the RSPB. In our interview, Emma shared details about this one-off live event, including its importance, what it represents and what she hopes people will take home and remember long after the concert is over. She also offered insights on her role, as well as the priorities and challenges for the charity.

Firstly, can you tell us a little bit about yourself and your role at the RSPB?

I was brought up on a farm in the Midlands (of England, UK) where my dad was a farm worker. I spent my childhood days exploring the fields, hedges and trees. I remember such a sense of freedom and the abundance of nature. That all changed as I grew older. Agricultural practices intensified and I watched the depletion of wildlife in front of me. That feeling of loss stayed with me and has driven my passion for conservation ever since.

My route into a conservation career was definitely not ‘standard’. My parents wanted me to be the first member of our extended family to go to university and a degree in International Relations, including the international politics of the environment, was my next step. I then navigated a route through the public sector, the commercial world in technology and finally landed in charity. I spent ten years in the waste and recycling sector, focusing on delivering behaviour change around food waste, which led to where I wanted and needed to be – in nature conservation and the incredible RSPB.

I joined RSPB in early 2016 as the Director for the Midlands, overseeing our network of landscapes, reserves, fundraising and comms, moving to be Director for the whole of England in 2019. In late 2022 I was able to bring together all of the experience I’d gained over the years, from Technology, to campaigning, to conservation, becoming the Executive Director for Digital Technology and Communications, sitting on the Executive Board.

Every day is different. One day I can be immersed in helping my team gear up our technology and media to deliver big events (such as Big Garden Bird Watch), the next pivoting and scaling up our comms and campaigning to unexpected legislative threats to nature, to speaking on the Radio 4 Today programme or R5Live about the incredible successes our teams have had with bringing threatened species like the Crane back from the brink of extinction. Another day I’ll be deeply immersed in developing the RSPBs strategy and reporting impact against it, the next working with Trustees, and when I’m really lucky it will be spent at one of our incredible 200+ nature reserves, seeing the spectacular conservation delivery and engagement that our teams do so well. It’s such a varied, dynamic and interesting role leading and working with some brilliant people – I’m incredibly lucky.

The RSPB has been around since 1889, and over the years it has developed and grown significantly. What would you say are its current priorities for nature, and where do you see the organisation going?

Emily Williamson, Etta Lemon and Eliza Phillips started the RSPB in the late 19th century, and the campaign they ran to ban the plumage trade (which was putting 60 bird species at risk of extinction) took three decades before it bore fruition. The tenacity and determination they demonstrated, when societal norms were stacked against them, was inspirational. When they started their campaign, women didn’t even have the vote, but they were convinced they could put an end to the trade, and they did. For me this determination and tenacity runs through the RSPB to this day. They used every tool at their disposal, just as we do today, campaigning with the public to drive awareness and support, engaging with politicians to drive legislative change and using science to gain credibility.

Our world-leading research allows us to take a bird’s eye view of the overarching problems facing nature and then pinpoint solutions that make a real difference. The world around us and the threats to birds and wildlife has changed significantly since the RSPB was created and so we have had to constantly evolve and change. Today we’re the UK’s largest nature conservation charity, with nearly 1.2 million members. We manage more than 200 nature reserves across all four countries of the UK, covering an area the size of 250,000 football pitches, making us the UK’s 5th largest landowner. Across those landscapes over 18,700 different species have been recorded. 85% of our workforce are volunteers, spending 1 million hours acting for nature every year. And we now have over 130 local groups spread right across the UK, connecting people and progressing conservation projects. We want to grow the number of people engaging with us as members, supporters, donors, volunteers, all taking action so that we can achieve a shared world where wildlife, wild places and all people thrive together. To do that we need to protect and restore habitats and landscapes, save species, help end the nature crisis, and inspire others to do the same. That’s a big ask but if anyone can do it, we can.

In particular in the UK our priorities are around demonstrating the art of the possible in terms of conservation on our nature reserves, and influencing nature-positive management at scale through partnerships in our Priority Landscapes; Internationally working with and through the BirdLife International partnership to deliver significant positive conservation impacts around the world; working to reduce the harmful impacts of selected fisheries around the world and marine development in the UK; getting the most important places protected through strengthened policy, and tackling threats to priority species; working tirelessly to secure the future of threatened species; working in partnership with the farming community across the UK, providing evidence-based advice to farmers, Governments and businesses, demonstrating good practice and developing and promoting policy frameworks that would enable a fair transition to nature-friendly farming; advocating for new income streams for nature so more can be invested in species and habitat recovery; and continuing to engage and empower more, and more diverse, people to take meaningful action alongside us to achieve all this. Ultimately, just like back in 1889, we think and act big. We deliver conservation you can see from space.

The Night of Nature concert seems like a new and exciting direction for RSPB engagement events. What inspired you to branch out?

Whilst Night of Nature is a bit of a first of its kind event for the RSPB, we nonetheless have a rich history of collaborating with voices from across the arts in order to bring nature to ever wider audiences. Back in 2022 we worked with international choreographer Sadeck Waff and agency 89up to create a ‘human murmuration’– a choreographed performance inspired by the stunning display birds put on as they flock together in a dance-like movement, emphasising the importance of working together to create impact. The murmuration was shown at COP15 where the Global Biodiversity Framework was agreed at the 11th hour. One of our current conservation milestones is the 50th anniversary of the re-introduction of White-tailed Eagles to the UK. To celebrate this achievement, we’ve partnered with acclaimed musician and sound artist Alice Boyd, who has just released a new track ‘Return of the White-Tailed Eagle’ (now streaming here) in tribute to the species. Alice also features – alongside RSPB ambassadors Dave Sexton and Nadeem Perera – in a forthcoming RSPB short film, ‘Return’, which documents the decades of conservation work by RSPB and our partners to bring the species back from the brink of extinction. ‘Return’ will release on August 29, with the trailer now streaming here.

We know just how important the voices of the creative community are to articulating the stories that drive our conservation work, and we’re thrilled to develop this relationship even further with Night of Nature.

Can you tell us a bit about the concert and what people can look forward to?

Night of Nature will blend live music with a cinematic celebration of nature. Stunning footage of the incredible species and habitats that we’re working to safeguard will be showcased on the Troxy’s big screen, synched to performances from #1-charting vocal group G4 and the Vesper string quartet. The evening will be hosted by RSPB Ambassador, actor/director Samuel West.

Think of this as a red-carpet experience—without the red-carpet price tag. With tickets starting at just £28, guests can enjoy an unforgettable show, mingle with our team, and even pose for a photo on the red carpet. It’s excitement, and entertainment—all within reach.

You have some exciting names attached to this event, how did they come to be involved?

G4 was a natural choice for Night of Nature. With their stunning harmonies and emotive performances, they bring a powerful sense of atmosphere to every stage they grace. But beyond the music, what really drew us to G4 was their genuine appreciation for the natural world. That really matters to us.

As a group that tours extensively across the UK and Ireland, G4 have had the chance to experience some of the country’s most breathtaking landscapes—from the dramatic coastlines of Scotland to the peaceful beaches of Devon, the wild beauty of Ireland, and the rolling hills of Yorkshire. Along the way, they make a point of pausing to soak in the scenery and observe the wildlife around them—often sharing these moments and photos with their fans on social media. It’s a window into the quieter, more reflective side of life on tour, and a reminder of how closely nature and creativity are intertwined.

With families of their own, the band feel a deepening responsibility to protect these places—not just for today, but for the generations that follow. When invited to take part in Night of Nature, they were immediately drawn to the idea of using music to celebrate the beauty of our world and support the vital work of the RSPB. For G4, this event is more than a performance—it’s a chance to help inspire others to cherish and protect the natural world.

Samuel West is an actor (currently playing Siegfried Farnon in All Creatures Great and Small on Channel 5) and director, and a keen birder for nearly twenty years. Speaking about his connection to RSPB and its work, Samuel says; “Until birds get their act together and organise their own pressure groups, I suppose we’ll just have to do it for them. With nature under unprecedented attack, the RSPB shows those in power what a huge and vocal nature lobby can do to change things. Our two young daughters love nature, and watching birds in particular. But the world they’ll inherit is in trouble. Half of all bird species worldwide are in decline. Biodiversity isn’t just a nice thing to have, it’s essential for the survival of humanity and the planet.”

Accessibility and connection to nature appear to be key inspirations for this event. What are you hoping to achieve with the Night of Nature concert?

In essence, Night of Nature is our way of saying a very heartfelt ‘thank you’ to all our members and supporters for their backing, without which we wouldn’t be able to deliver the vital work needed to protect and maintain the stunning array of species and habitats you’ll experience up on the Troxy’s big screen.

But we also know that we need more people to join us in taking action for nature. So we hope this also inspires even more people to come along and be a part of something bigger. Whatever you do – big or small – matters. It all joins up to create real and lasting change. Furthermore, research also demonstrates that connection to nature is in turn good for our own mental & physical well-being. Good for people and good for nature.

It’s our hope that Night of Nature galvanises even more of us to join the fight against biodiversity loss and work to tackle the climate crisis, as we strive towards a shared world, where wildlife, wild places and people all thrive alongside each other.

EBHL Conference – Paris, May 2025

NHBS colleague Leon recently attended the general meeting of the European Botanical and Horticultural Libraries Group, or EBHL for short, which this year took place in Paris from May 14th to 17th. This annual conference brought together librarians and archivists from academic libraries and herbaria for several days of talks and behind-the-scenes tours at four outstanding locations in Paris. We have attended previous meetings in Brussels and London, and this continues to be a valuable occasion to meet some of our key customers from across Europe and the USA in person. The overarching theme of this year’s meeting was “Plant Sources;” branching out into three topic areas over three consecutive days.

A view of the Jardin des Plantes and part of the Paris Natural History Museum.

Day 1

The first day took place just outside the Paris Natural History Museum and its botanical gardens and discussed new tools for botanical and horticultural documentation. This included approaches to preserving the illustrations in the herbarium of Bonpland and Humboldt, how bibliographic metadata reflects historical developments in taxonomy, and an introduction to World Flora Online, a global resource for botanical information. After lunch, delegates were split into several groups and taken around the special collections section of the Central Library, which featured a collection of remarkable historical wax models of fruit and fungi that were used in teaching. We were also amazed to see the museum’s restorators at work in the basement’s book and paper restoration workshop, surrounded by a collection of vintage hand tools and presses. The craft and skill on display here were, frankly, astonishing. The day was completed by a trip around the botany library and its enormous herbarium storing dried plant specimens, including some remarkable collections of original herbaria and exsiccata from Humboldt and other historical collectors.

On Wednesday, the conference continued at the Institut de France in the heart of Paris, right next to the Seine, and discussed private herbaria. A series of talks introduced us to some remarkable historical figures, including Benjamin Delessert, the Girardin family, and the tragically short-lived Auguste Pervillé, who died aged 33. Details of their lives and the impact they have had on the history of botany are ongoing areas of research. After a brief tour of the stunning library of the Institut de France, we were expected back at the Natural History Museum for a guided tour of its famed Jardin des Plantes. After this, I had the opportunity for a quick visit to the museum’s comparative zoology and palaeontology galleries, which have been high on my bucket list for Paris. The group reconvened in the evening at a rather unique venue, the moored barge “L’Eau et les Rêves” that doubles up as a floating café and Paris’s only botanical bookstore.

Day 3

Given the meeting’s theme for the third day, “Understanding French Horticulture”, we were originally supposed to convene at the Société Nationale d’Horticulture de France (SNHF) but, due to ongoing building and restoration works, were instead hosted at the Ácademie d’Agriculture. After being greeted by a bust of none other than Louis Pasteur, we listened to presentations from visiting scholars on, amongst others, SNHF’s historical bulletins and what they reveal about how horticulture grew and developed in France, the remarkable early-20th century autochrome and film collection of the Albert Kahn gardens (subject of the book Natures Vivantes), and the botanical iconography that can be found in the Decorative Arts Library. The latter was a visually rich talk on how botany has influenced ornaments used in print and sculpture.

One of the beautiful libraries in the French Senate.

In the afternoon, we were allowed access to several libraries inside the French Senate and taken on a tour of the adjacent gardens, the famed Jardin du Luxembourg. In the evening, we went back to the academy for a remarkable presentation of the book Les Raisins de Redouté, which reproduces historical paintings of grapes and grapevines. After having gone missing for over a century, this collection of 83 paintings on vellum was rediscovered in the academy’s archives in 2018 and reproduced in this handsome, large-format book while the originals, valued at some 6 million euros, have been stored in safer environs.

Day 4

The final day of the EBHL conference entailed a visit to Versailles, specifically to the Potager du Roi, the King’s vegetable garden, and the library of the adjacent École Nationale Supérieure de Paysage. This working garden used to supply food to the courtiers at Versailles at a time when year-round availability of fresh fruit and vegetables was still largely unheard of. The garden is in the process of being restored and has a long and storied history. In the library, the archivists treated us to numerous original maps from their collections that show plans of this and other gardens in Paris.

The meeting was a great opportunity to catch up with existing customers and hear what their institutes are up to. We are looking forward to the next meeting and would like to thank the organizers of this year’s conference, in particular Florence Tessier, Sabrina Castandet-Le Bris, Mégane Pulby, and Audrey Lumière.

NHBS welcomes opportunities to develop closer ties with the professional and amateur organisations that we count amongst our customers, whether through attendance or sponsorship. Do not hesitate to reach out to us.

2025 Biological Recorders Conference for Cornwall and Isles of Scilly

I recently had the opportunity to run a group workshop at the 2025 Biological Recorders Conference for Cornwall and Isles of Scilly – a fantastic day dedicated to celebrating the vital wildlife recording efforts in Cornwall. Held at the University of Exeter’s Penryn Campus, the event brought together a diverse group – from those just starting their wildlife observation journey to seasoned experts, all sharing a genuine passion for the county’s natural wonders. It was inspiring to network with fellow enthusiasts, and the range of workshops and insights into the latest projects was truly exciting.

This year’s focus, ‘Data for the Future: Recording Nature in a Changing World’ was particularly thought-provoking. The conference explored the recent shifts in recording methods, including the increasing adoption of structured monitoring, the exciting technology used in recording and the value of traditional techniques. It was a valuable day, and I’m looking forward to sharing some of my key takeaways from the event.

Key highlights

It was great to connect with so many people with unique and varied interests. I spent most of my morning meeting lots of likeminded people who are interested in biological recording, chatting all things equipment and answering lots of questions about the kit. Throughout the day, I attended some interesting talks from a number of researchers and organisations. My highlights are as follows:

Pollinator Responses to Urban Green Environments – Oliver Poole, University of Exeter

Oliver’s research focussed on planting green spaces, and whether green spaces are working for both pollinators and people. His research wanted to find out what delivers the most benefits to these groups, and interestingly, his results showed that a mix of native and ornamental plants had the best scores for pollinators and people.

Sea Bass Monitoring, Robin Bradley

This talk centred on the work of a volunteer group, who record data on juvenile bass in the Fal, Helford and Camel estuaries to analyse the strength of each successive year class. Their valuable data has now been validated and added to a larger dataset that will contribute to work across Europe. I particularly enjoyed the wider message of this talk, which emphasised the importance and value of community and citizen science in the wildlife space.

Tor to Shore – Recording Opportunities, Dr Gwen Maggs

Another interesting talk discussing the Tor to Shore project, an expansive undertaking from Cornwall Wildlife Trust to create a Local Nature Recovery Network spanning across land and sea. The talk discussed the project, and the work on the Trust’s farm, linking to lowlands, an expanding sand dune system, and into the sea with seagrass and maerl habitats.

Data for the Future: Hardware in the Field

I had the opportunity to speak in a group workshop, where I demonstrated some wildlife recording kit and discussed the different types of hardware that can be used for a range of monitoring. It was great to demonstrate the capabilities of wildlife equipment and their applications in the field, and I was able to cover a wide range of monitoring including traditional methods, acoustics, telemetry, video and thermal imaging.

I started with a focus on traditional monitoring, before moving on to advancements in the sector and its technology across a range of habitats and environments. I covered a range of equipment, from bat detectors and camera traps to thermal imaging and our upcoming NEWTCAM. It was great to receive such interest in the kit, and with wildlife technology becoming more and more accessible, it is a great opportunity to share the latest technology to wildlife recorders in the South-west.

It was great to meet so many likeminded individuals interested in biological recording and I particularly enjoyed the emphasis, and appreciation of, citizen science and the value that community can bring to conservation. Overall, it was an inspiring day, and I look forward to attending next year’s conference!

UK Moth Recorders’ Meeting 2025

Butterfly Conservation’s Moth Recorders Meeting provides an essential update for ecologists, wildlife watchers, and naturalists interested in the latest developments in moth recording, research, and conservation. Introduced by director of business and research, Russel Hobson, this year’s meeting was held online via Zoom on Saturday 25th January, and comprised of a variety of talks by keynote speakers including Dr Zoë Randle, David Hill and Dr Avalon Owens.

Dr Zoë Randle, Butterfly Conservation: National Moth Recording Scheme Update

The first speaker, Butterfly Conservation’s Dr Zoë Randle, shared an update on the National Moth Recording Scheme and key trends. Over 600,000 observations were submitted on iRecord throughout2024, bringing the total macro moth records to 36.2 million and micro moth records to 7.4 million in the National Moth Recording Scheme. Despite an increase in moth recording last year, Zoë emphasised the importance of both recorders and verifiers, while also stressing the need for more volunteers to streamline the verification process.

Dr Norman Lowe, County Moth Recorder, Breconshire: Charismatic Clearwings in mid-Wales.

Dr Norman Lowe, County Moth Recorder for Breconshire, discussed clearwings in mid-Wales, presenting the group as flagships for dayflying moths and provided an update on clearwing records during 2024. Last year, 31 more recorders and ten more pheromone traps/lures were supplied to aid in recording, resulting in a total of 80 clearwing observations for 2024. Data revealed some local and scarce species, including the Welsh Clearwing and Red-tipped Clearwings, and highlighted species which are common and widespread, like Lunar Hornet Moths.

David Hill, Conservation Manager (Scotland), Butterfly Conservation: Black, White, Red & Gold – surveying Argyll’s rare moths

Next to speak was David Hill, who reported on two key species that he has been working with in Scotland: White Spotted Sable Moths and Transparent Burnet. He discussed the background and biology of the species, as well as the efforts undertaken to better understand their pressures and distribution.

2024 larval surveys uncovered 30 White Spotted Sable caterpillars over three days and allowed surveyors to categorise habitat. This coming year, the team will look to rear caterpillars to confirm identification, start adult surveys and seek out sites where Anania terrealis, a commonly mistaken species, is present.
Transparent Burnets are a focus for Scottish conservation projects as part of the Species on the Edge programme. This rarely recorded species is one of concern due to loss of suitable habitat and work will continue throughout 2025 to establish the distribution and abundance of this moth across Argyll.

Dr Luke Evans, Butterfly Conservation: Can we measure the impact of insect change on bird and bat populations?

Dr Luke Evans discussed the DRUID project, which has operated since 2021 and aims to investigate the drivers and repercussions of UK insect decline. Evans discussed the impact of this catastrophic decline on species whose diets are adapted to insects, true correlation vs random correlation (the observation data conundrum) and the suggestive patterns of decline in birds as a result of this. The use of key data, including that in the National Moth Recording Scheme, demonstrates the importance of national monitoring data for evaluating insect abundance and the direct impacts of insect change.

Dr Sam Fabian, Imperial College London: Understanding why artificial lights trap flying insects using high-speed videography

The next presentation was delivered by Dr Sam Fabian, who explored the aggregation of insects around bright light sources, how artificial light can impact insect flight and the behavioural mechanisms behind it. Fabian suggests that circling behaviour around bright light sources is due to dorsal light response – a stabilising reflex where insects angle their body to orientate bright lights above them – which causes erratic flight paths around artificial light sources.

Dr Avalon Owens, Rowland Institute, Harvard University: Do sustainable lighting practices sustain moths?

Last to speak was Dr Avalon Owens, who concluded the session with an insightful discussion on the impacts of light pollution on moths. This growing threat is one of many that impacts global insect abundance and diversity, and can have a range of negative impacts on insect behaviour, including: fatal attraction, temporal and spatial disorientation and visual confusion. These can have catastrophic effects on insects internal body clock, navigation ability and recognition of resources. With light pollution levels growing and expanding exponentially, Dr Owens also outlined key routes to tackle the issue by creating sustainable lighting that is useful, targeted, controlled, low level and warm coloured.

National Nest Box Week 2025

Friday 14th February marks the start of National Nest Box Week. With widespread population declines due to habitat loss and urbanisation, National Nest Box Week presents us with the perfect opportunity to provide habitat for local birds, boosting breeding success and contributing to the enhancement of biodiversity in our green spaces.

Mid-February marks the start of the breeding season for many British bird species, with many beginning to actively seek new territory and suitable nesting sites. Nest Box Week is a great time to install a new nest box or do some maintenance on any existing boxes. By providing artificial nesting sites, we can assist species such as Robins, House Sparrows, and Swifts, while simultaneously raising public awareness about the diverse range of birds that benefit from these resources.

Here are some ways to get involved in National Nest Box Week:

Install a nest box in an outside space, garden or balcony
Plant native flora and provide access to fresh, clean water to keep your garden bird-friendly
Support bird conservation organisations by donating, volunteering or sharing their work
Encourage friends and family to get involved in supporting their local wildlife

Garden Bird Species

Robins are a familiar sight in UK gardens and are easily recognised by their bright red breast and cheerful song. They prefer open-fronted nest boxes, often tucked away in hedges or shrubs, to mimic their natural nesting preferences in sheltered crevices and vegetation.

Blue tits are small, vibrant birds common across the UK that are often seen flitting through gardens and woodlands. They prefer small, enclosed nest boxes, hung high to mimic their natural nesting sites in tree cavities.

With their distinctive yellow beak and melodious song, Blackbirds are a common sight in various habitats across the UK. They prefer open-fronted nest boxes, at a slightly higher location, tucked away amongst dense vegetation or climbing plants for added security.

House Sparrow perched on balcony railing

Common in UK gardens and urban areas, Sparrows prefer nest boxes with a small entrance hole, placed high up on walls or under the eaves of houses, mimicking their natural nesting sites in crevices and holes in buildings.

Why is National Nest Box Week important?

Increasing urbanisation, human development and changing land-use have had devastating impacts on bird populations in the UK. A loss of natural nesting habitats has introduced extra challenges for rearing young, and nest boxes provide nesting birds with vital habitat to rear chicks – helping to mitigate the impacts of habitat loss which is essential for supporting local bird populations.

Training Course: Bats for Building Professionals

The recent training course by the Bat Conservation Trust, Bats for Building Professionals, aimed to provide direction and understanding on the legal protections surrounding bats and their roosts in buildings. Suitable for contractors, pest controllers, surveyors, architects or those working within the construction industry, the session aided building professionals in developing their bat roost identification skills and taught them how to navigate situations where bats are present on site.

The seven-hour course, run over two interactive online sessions, explored bat ecology, biology, best practices, the latest guidance and legal information.

The course began with a comprehensive overview of Britain’s breeding bat species, covering their biology, ecology, adaptations, habitat preferences and roosting types. Speaker Katie Swift introduced the Bat Calendar – a particularly interesting aspect of the session which revealed how contractors and construction workers can plan work around bat activity to minimise disturbances (see below).

This led to a discussion of bat roosts in built structures, where Katie explained why bats favour these spaces and detailed attractive features for both cavity and crevice roosting species, such as soffits, eaves, and cladding. Exploring the different uses of these roosts throughout the year, Katie highlighted how occupied spaces change between summer and winter, and which bat species commonly utilise buildings for this purpose. Using examples like pipistrelles and horseshoe bats, she demonstrated how different species utilize roosting sites and how to recognize an active roost.

The second part of the discussion focused on legislation and bat protection, educating attendees on the laws that are in place to ensure bat protection, actions that are considered an offence, and highlighting advice services available. Katie then reviewed the European Protected Species License, explaining its role in safeguarding bats within the UK, outlining how construction activities can potentially harm bats in buildings, and when to seek advice as a building professional in keeping with best practice guidelines.

The second session concluded with an interactive quiz of working examples for building professionals, covering a range of typical building works including barn conversions, door repairs and gutter replacements.

The ‘homework’ task between sessions was a particularly enjoyable aspect of the course – through independent field work, attendees had the opportunity to report on the potential bat features of their chosen building or structure and apply the knowledge learned throughout the session to understand which species may be present in the area, the areas bats may utilise on the structure and what works might impact a roost.

This insightful and informative training course provides a valuable resource for building professionals seeking to learn or refresh their knowledge about bats and building projects. The speaker’s expertise ensured a comprehensive and engaging learning experience, covering everything from bat ecology, to bats in buildings and licensing.

Conference: Rewilding Futures Shaping Tomorrow’s Wild 2025

Although the term was initially coined in the 1990s, ‘rewilding’ has come to dominate conservation thinking in the last fifteen years. This seemingly paradigmatic shift was consequent of a growing perception that a vision of planetary future should not merely appease a bare minimum criterion for ecological longevity. Instead, conservationists should envision an ecologically prosperous future that supersedes the conditions of the present or the recent past. Many of the initiatives enacted under the banner of ‘rewilding’ may be seen as the attempted actualisation of this vision.

Six years have passed since Citizen Zoo’s original Rewilding Symposium in 2019. This period has seen a rapid acceleration in the global recognition of rewilding alongside the now widespread presence of rewilding initiatives. The growth and support of the rewilding movement has coincided, of course, with the continued acceleration of global biodiversity loss and the increasingly unignorable impacts of anthropogenic climate change. The common philosophy across the sometimes-disparate presentations of participants was that the process of actively reinstating biodiversity is inextricably tied to the viability of our planetary future.

Rewilding Futures played host to a globally diverse set of speakers from organisations including Rewilding Chile; Rewilding Europe; Rewilding Britain; Gorongosa National Park (Mozambique), Blue Marine Foundation; The Wildlife Trusts and Rewilding Argentina.

This year, the University of Cambridge played host to the conference, bringing together leading voices to tackle pivotal issues in the field and discuss the future of rewilding in the coming decades. Key highlights for me were as follows:

Carnivore Reintroductions

Luigi Boitani asked, ‘What role for wolves in Europe?’ – a fascinating presentation which argued for the conservation status and continued legal protection of wolves across the continent. The recovery of the species has been successful across swathes of Europe, and this has raised questions of the potential down listing of the species. Most interestingly, the presentation pulled into question the oft perceived justification for wolf reintroduction – their capacity to create a trophic cascade of top-down ecological restoration. The speaker argued that this justification has been historically overstated in the same way that their potential to prey on livestock has been underplayed. For Boitani, we must acknowledge that our desire for the presence of wolves is based on our perception of the species’ intrinsic value and simultaneously the real concerns about livestock predation must be mitigated.

A presentation from Scotland: The Big Picture provided a summary of their efforts in working towards a reintroduction of Eurasian Lynx in Scotland. Similarly to Boitani’s consideration of wolves in Europe, they also acknowledged that the carnivore’s potential to prey on livestock has been understated by previous groups who have lobbied for lynx reintroduction. Most importantly, Scotland: The Big Picture acknowledged the necessity of garnering support from stakeholders who may be impacted by the presence of lynx. The organisation’s more clearheaded approach to the possibility of lynx reintroduction in Scotland marked a stark contrast to the mysterious and illegal releases in the Cairngorms which preceded the conference.

Perhaps the most contentious presentation of the event came from the Colossal Foundation – a Texan initiative that claims they are enacting a process of Thylacine ‘de-extinction’. A mandated project will see the Tasmanian Tiger, extinct since 1936, re-animated and playing a significant role in future Tasmanian ecology. This, alongside their programme of Woolly Mammoth ‘de-extinction’, could be perceived as representing the boldest outreaches of the rewilding movement. Pragmatists within the conference raised concerns about the detrimental implications that this unprecedented project, the mandate of which transcends ordinary legal barriers to reintroduction, could have on Tasmanian ecology.

Land for rewilding: Legal mechanisms and Ownership

The Lifescape Project offered an analysis of the legal mechanisms used to secure land for long-term rewilding, such as conservation covenants in England and conservation burdens in Scotland. Their talk Using Novel Legal Mechanisms to Secure Land for Rewilding: Lessons from across UK and Europe outlined the ways in which various mechanisms allow or impede the long-term dedication of land for rewilding. Utilising cross comparison case studies from across Europe, this talk encouraged innovative and collaborative approaches to improving land use legislation.

Similarly, Ted Theisinger’s workshop To Own and Control: The Future of Land Governance Structures in Scotland and Beyond presented an interesting consideration of the future of conservation in Scotland. Scotland is one of the most depleted terrestrial landscapes and simultaneously has one of the most concentrated structures of land ownership in the world. Throughout the workshop, participants considered the ways in which existing legislative instruments define the parameters of conservation within the context of Scottish land ownership. The workshop oriented toward imagining a future where non-human voices were interwoven into considerations of what to do with our lands and seas.

Peatland Restoration

Among the many intriguing discussions of individual sites where rewilding is enacted was Andrew Osborne’s historical ecology of Chat Moss, a 36km square area of lowland raised bog in Salford. The presentation traced the history of Chat Moss over the last 200 years, including industrial habitat destruction which resulted in a significant loss of flora and fauna in the area. The talk highlighted the work of restoration projects dating back to the 1980s, driven by the imperative to preserve carbon stored in the peat and encourage carbon sequestration. Consequentially, the last forty years have seen the translocations of many species into the area, including the recent reintroduction of the Large Heath Butterfly (Coenonympha tullia).

Marine Rewilding

Another highlight was the Blue Marine Foundation’s presentation Rewilding the Seas: A modern odyssey of hope and challenge. Charles Clover outlined the work of the Blue Marine Foundation and looked to answer the question: why rewild the sea, which in comparison to land, is seemingly already wild? The presentation argued that the principles of sea rewilding are essentially the same as that of land, to bring back lost and depleted species to our oceans and restore ecosystems that have been harmed by human activities?– simply by stepping back and letting nature repair the damage, or by reintroducing species/ restoring habitats.

Final Thoughts

While aspects of rewilding remain deeply contentious and there continues to be a vast diversity in perspectives of what rewilding should and could be, the most substantial thematic takeaway is that rewilding has galvanised people in a way that traditional conservation approaches have not.

In 2025, the impacts of anthropogenic climate change and unprecedented biodiversity loss are met with deterministically inactive governing bodies across the globe. In many ways things seem more hopeless than ever before, yet actors within the conservation field understand that without hope there can be no inspiration for change.

The revolutionary potential of the rewilding movement has come to represent the last beacon of hope for a viable future for people and nature – a possible catalyst for change.

The Big Butterfly Count: NHBS Staff Results 2024

Each year, Butterfly Conservation urges the public to venture outdoors and record their local lepidoptera populations with the Big Butterfly Count – a UK-wide survey aiming to assess the health of butterflies and day-flying moths. The count involves recording the number and species of butterflies in a chosen area for fifteen minutes and uploading results to their official website.

There are around 130 day-flying macro moths and 59 species of butterfly in the UK. These highly sensitive animals are key indicators of environmental health and play a crucial role in pollination across the country. The latest State of the UK Butterflies report, an assessment on British butterflies, found that the group has declined by 80% since the 1970s. The Big Butterfly Count allows the health and trends of these species to be assessed, improving our understanding of their conservation and threats.

This year’s count took place between Friday 12th July and Sunday 4th August, and the results from nationwide counts can be found on Butterfly Conservation’s interactive map. Over 140,000 counts were taken during this time, recording nearly 1,000,000 butterflies. Gatekeeper (Pyronia tithonus), Meadow Brown (Maniola jurtina), Large White (Pieris brassicae), Small White (Pieris rapae) and Peacock (Aglais io) butterflies were the most recorded species across all data points, accounting for over 670,000 sightings.

This years count revealed the lowest numbers on record, and has led to the announcement of a nationwide ‘butterfly emergency’. On average, seven butterflies and day-flying moths were seen per count, half of last years average. This years count observed significant downward trends in the group, with around 81% of species showing declines, and 600,000 less butterflies recorded than last year (which equates to around a third of 2023’s total observations). 9,000 counts did not record any butterflies, which is the highest number recorded in the history of the count.

We participated in the Big Butterfly Count this year, and are excited to share our results below.

How Can We Use Sound to Measure Biodiversity? – Webinar Round-up

In July, the Biological Recording Company held the first of three webinars on bioacoustics in conservation. These webinars, which are presented in partnership with Wilder Sensing, Wildlife Acoustics and NHBS, began with a general introduction to bioacoustics, and will be followed with two sessions later in the year discussing the technology in more detail.

In the first webinar, talks by Geoff Carss of Wilder Sensing and Joe Hampson from the Somerset Wildlife Trust provided listeners with an overview of bioacoustic technology, its applications in measuring diversity and a short story of Honeygar farm, the Trust’s first ‘wilded’ site. NHBS are pleased to have sponsored this webinar, and we would like to thank participants who took part in our prize draw to win a Song Meter Micro 2.

Wilder Sensing: An entry-level introduction to bioacoustics

Bioacoustics provides ecologists and conservationists with an auditable, low-cost technology to measure biodiversity. It involves the use of audio recorders to passively detect sound in an environment, which can then be analysed to provide insights into community assemblage.

This technology can be used to measure several environmental variables, including animal presence, soil health, weather and infrastructure. Long-term monitoring of an environment can provide us with new insights on the richness and species density of an area and can even be used to analyse migration of key groups. Analysis can also determine areas of interest and habitat preferences for certain species, which can be used to inform future land management.

This method removes bias from traditional surveying techniques, where the skill and age of the observer, or sometimes even the day itself, can impact the result of a traditional survey. However, there are some limitations associated with this technology. False positives (the technology can misidentify a species), false negatives (the technology might miss a call), poor sound quality and mimicry can impact the accuracy of recorded data. To capture an accurate picture of community assemblage, passive recording is best used in partnership with traditional site surveying. This way, disturbance and false negatives can be mitigated, and through bioacoustic surveys, we can revisit the recordings as technology develops.

Somerset Wildlife Trust: Honeygar Farm Case study

Honeygar Farm is an 81-hectare site of former intensive farmland, now owned by the Somerset Wildlife Trust (SWT). Since acquiring Honeygar, SWT have employed a unique ‘wilded’ approach to restoring the site.

Changes in hydrology management were among the biggest alterations at Honeygar, as the site has been subject to intense peat drainage to make way for agriculture. Honeygar has over two metres depth of peat, equivalent to 100,000 tons of carbon dioxide, so restoring the natural peatland by blocking drainage ditches was key to improving the carbon storage on site. Cutting and grazing by cattle, historically a huge pressure, has also been reduced from a herd of around 140 animals to 40 individuals. This, partnered with limited silage cutting and resting fields from grazing, is encouraging recovery of the botanical communities on site. The Trust is also exploring the use of different ungulates, including goats, ponies and different cow breeds, to better support the wetland habitat.

Over 20 months, nearly 13 million records were gathered using four sensors on site. This monitoring was undertaken alongside breeding bird, wintering bird and breeding wader surveys to provide a more detailed picture of community assemblage, confirmed with manual validation and targeted surveys to assess rare bird presence. Honeygar will continue to be monitored for insects, birds, mammals, fungi and plants to inform future management practices.

Honeygar Farm is the Trust’s flagship site for the ‘wilding’ approach

Formerly an agricultural farm, Honeygar is being restored to its natural peatland habitat through alterations in landscape management

Bioacoustic technology has provided insight into the community assemblage at the farm, helping to inform landscape management.

This webinar was an enlightening insight into bioacoustics and highlighted some interesting points on its conservation applications. Read our Q&A with Geoff to hear more about Wilder Sensing and its technology, and find more details on Honeygar on the Somerset Wildlife Trust website.

Going to Bat for Bioacoustics: How Acoustic Monitoring is Helping to Save Bats – Webinar Round-up

Recently, Wildlife Acoustics and Bat Conservation International partnered together to host a webinar highlighting the use of bioacoustics in bat conservation across the globe. The webinar featured three case studies tackling the impacts of white-nose syndrome, habitat loss and climate change with the help of bioacoustic technology. Here, we provide a summary of these case studies and the applications of acoustic monitoring in these investigations.

Florida USA, Dr. Melquisedec Gamba-Rios

Endemic to the region, the Florida Bonneted Bat (Eumops floridanus) is increasingly threatened by habitat loss from sea level rise and destructive development. This species has one of the smallest ranges in Southern Florida and utilises old tree cavities and large, open spaces for roosting and feeding. Dr. Gamba-Rios and his team sought to identify critical habitat for this endangered species using bioacoustics, hoping to support their fragile populations.

The team used acoustic recorders to identify key roosting and feeding areas for the species. Interestingly, they found that Miami’s zoo, golf courses and tropical parks had high numbers of Florida Bonneted Bat calls. The research showed that the large, open areas surrounded by forest and absence of artificial light of these locations provided an ideal foraging space for the species.

Since these bats require older, cavitied trees, the habitat of the group is at risk as development increases. Plans for water park construction were proposed on a key site for this species, however the evidence gathered here was used to challenge the proposal, resulting in its rejection to protect key bat habitat. In March 2024, over 1.1 million acres of critical habitat were designated for the species in Florida, including foraging areas in urban habitat and over 4,000 acres of Miami Pine Rocklands. Federally protected species are known to be twice as likely to move toward recovery than those without protection, so the designation of these spaces is incredibly important in securing the future of this species.

Nyungwe National Park, Dr. Jon Flanders

Last seen in 1981, the Hill’s Horseshoe Bat (Rhinolophus hilli) was considered a ‘lost’ species in Rwanda. In January 2019, a group of scientists and researchers, including Dr. Jon Flanders, set out on a 10-day expedition in Nyungwe National Park, looking to rediscover this elusive animal.

Nyungwe National Park rangers played a key role in the early stages of this project, identifying caves and key habitat for bats in the area. The rangers conducted acoustic monitoring using SM4 Acoustics to identify foraging and roosting areas, collecting over 260,000 files of acoustic data. Eight of these recordings successfully detected the calls of the Hill’s Horseshoe Bat, found in small, defined ranges. During the 10-day trip, the team worked relentlessly to catch, measure and collect DNA samples from bats using mist nets and harp traps in these locations. The team successfully captured two Hill’s Horseshoe Bats and confirmed the capture of this critically endangered species with museum archive specimens. The expedition highlighted the spectacular diversity of Nyungwe National Park which features a large number of rare and endemic species, and these findings reinforce the parks importance as a biodiversity hotspot.

White-nose Syndrome, Dr. Amanda Adams

White-nose syndrome is a cold-loving, infectious fungal disease found in bats. The fungus manifests in a total skin infection, most visible around the muzzle of the animal. This infection is responsible for significant mortality in several species, where the infection causes bats to wake often during hibernation – burning their fat stores, causing dehydration and starvation. Infected bats can expend up to twice the amount of energy as healthy individuals during hibernation, severely impacting their ability to survive the winter. Because of this, six million animals have succumbed to this infection so far, impacting 12 out of 44 species found in the USA.

Dr. Amanda Adams sought to use bioacoustics to enhance the management of foraging habitat to support these species through hibernation. The team used the Song meter mini to search for the presence of bats and observe their feeding behaviours. They found that feeding behaviours were observed up to three times more in prey patches, and this allowed researchers to designate feeding habitats for affected species. The survey will be used to inform vegetative management on passing corridors, aiming to increase the productivity of foraging areas to support the health of infected bats.

The ‘Going to Bat for Bioacoustics’ webinar provided an engaging insight into the applications of acoustic monitoring in bat research, showing how the technology can be used to support bat conservation.
