European Botanical and Horticultural Libraries Group (EBHL) Annual Conference

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

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

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

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

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

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

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

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

Author interview with Mark Avery: Reflections

Reflections 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.

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!

Reflections by Mark Avery is now available in hardback and paperback from nhbs.com.

Science and Research

Scientists in the US have achieved net energy gain in a nuclear fusion reaction for a second time. This comes after a successful initial breakthrough test in December of last year. Nuclear fusion involves using heat energy to fuse two elements into forming a larger element and in the process releasing a burst of energy. If successful, this process could open the door to a potentially near-infinite supply of clean energy. However, scientists have cautioned that the technology is far from solving the climate crisis as significant hurdles remain before fusion power plants can be up and running.

Researchers are using machine learning to help identify underground fungal networks. Mycorrhizal fungi form an interface with plant roots and play an important role in nutrient and water transfer from the soil. They are also an important carbon store with a predicted 13 billion metric tons of carbon dioxide moving from plants to mycorrhizal networks each year. The Society for the Protection of Underground Networks (SPUN) is working to map mycorrhizal fungal networks across the world and, to aid this, they are employing a combination of remote-sensing technology and machine-learning algorithms. The algorithms are used to predict zones of high mycorrhizal diversity which researchers can then survey and take samples for laboratory analysis.

Climate Crisis

Oceans have hit their hottest temperature yet spelling dire consequences for marine biodiversity. Temperatures reached 20.96°C beating the 2016 record according to the EU’s Copernicus climate change service. Changing ocean temperatures can cause shifts in marine species distributions, impacting marine food webs. There has also been widespread coral bleaching as a result of changing temperatures. Rocketing ocean temperatures come after global average temperature records were broken on multiple occasions last month.

Wildfires have swept across the island of Maui with close to 100 deaths and many more missing. The town of Lahaina with a population of almost 13,000 was mostly destroyed in the worst Hawaiian natural disaster in more than 60 years. The incident comes after a wave of wildfires hit the South of Europe in July. Scientists have warned that climate change is creating conditions which make it much more likely for wildfires to spread. Wildfires are common in parts of Hawaii, but the scale of the recent blaze is largely unprecedented.

Conservation

Three baby beaver kits have been born in Somerset according to the National Trust. The kits were born on two different National Trust sites on the Holnicote Estate near Minehead. Beavers were initially introduced to the site in 2020, more than 400 years since beavers were last seen on Exmoor. The presence of beavers has considerably altered the water levels at the sites encouraging other species such as water voles, amphibians, fish and otters.

Extinction Risk

Falcon trafficking has soared in the Middle East driving a decline of wild populations in the region. Falconry is a popular sport in the oil-rich gulf countries of the Arabian Peninsula where there is a high demand for wild peregrine and saker falcons which are prised for their hunting abilities. Trade in wild falcons is restricted by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). High poverty rates in Syria, Iraq and Jordan, however, have driven many to the lucrative trade where enforcement by authorities is a low priority following decades of civil war and conflict.

Discoveries

Scientists have found two new types of mole in eastern Turkey. Talpa hakkariensis and Talpa davidiana tatvanensis were confirmed by DNA analysis to be biologically distinct from closely related moles. The two new types of moles live in the mountainous terrain of eastern Turkey surviving extreme temperatures and weather conditions.

South American frogs may be communicating with each other through the bioluminescence of their skin according to scientists. Fluorescence was first shown to be naturally occurring in amphibians in 2017 which initiated further research into the phenomenon. Researchers captured 528 frogs in Brazil, Colombia, Ecuador and Peru and found that all 151 frog species tested showed some degree of fluorescence. Fluorescence may make for a more noticeable display during mating calls in low light conditions. Green fluorescence is present in the vocal sac region of the frogs, and as the frogs call this region expands and contracts. Orange fluorescence could act as a warning signal to predators or serve as camouflage.

Conservation Volunteering at Prawle Point with Buglife

The NHBS team are passionate about nature and conservation, and to help them to get involved with local volunteer schemes, NHBS encourages colleagues to apply for up to three paid days each year to volunteer with a conservation project or organisation of their choice. Catherine Mitson, Assistant Editor for British Wildlife and Conservation Land Management, tells us about her time volunteering with Buglife and the bee species she is surveying.

The Long-horned Bee Eucera longicornis truly lives up to its name. The males sport bizarrely long antennae, and this in combination with their large size makes them instantly recognisable. Female Long-horned Bees, however, lack these oversized antennae and are more robust compared to the males, and can sometimes be confused with Anthophora (flower bees) species. Although the Long-horned Bee is a type of solitary bee and each female will dig her own nest hole, they tend to nest in aggregations in a variety of habitats, such as woodland rides and clearings, brownfield sites and coastal meadows. Here, however, we are focused on the south-facing soft cliffs along the South Devon coastline.

Prawle Point SSSI is a fantastic site for invertebrates, including the Long-horned Bee which can be found nesting in the cliff face or foraging on plants such as clovers, Bird’s-foot-trefoil and Narrow-leaved Everlasting-pea along the cliff top. What makes Prawle Point even more special is that it is the only site in the UK where the Long-horned Bee’s cuckoo, the Six-banded Nomad Bee Nomada sexfasciata, is known to be found. Like the bird, cuckoo bees lay their eggs in the nest of another bee, the host, and once hatched the larvae will eat the food stores that had been gathered by the host for its own larvae.

The Six-banded Nomad Bee is arguably the UK’s rarest bee, and relies on a healthy, viable population of its host. Sadly, due to the loss of flower-rich grassland, the Long-horned Bee has declined dramatically; once found in most southern English counties, its range is now restricted to the south coast of England and Wales with a few scattered inland sites. But a new project is hoping to turn the tide for the Long-horned Bee, the Six-banded Nomad Bee and many other rare invertebrates along the South Devon coast.

Life on the Edge

Life on the Edge, funded by the National Lottery Heritage Fund, is an exciting new partnership with South Devon Area of Outstanding Natural Beauty, Buglife, National Trust, Torbay Coast and Countryside Trust, and the South West Coast Path Association. Focused on the South Devon coast between Berry Head and Wembury, Life on the Edge is aiming to restore viable populations of some the UK’s rarest invertebrates, including the Six-Banded Nomad Bee, by expanding and reconnecting the vital coastal habitats on which these species depend. There are 30 invertebrate species that this project will support, such as the Moon Spider, Great Green Bush-cricket, Mediterranean Oil Beetle and the Devon Red-legged Robberfly, but of course, by improving and expanding the habitats used by these species, a plethora of wildlife will benefit.

Buglife will be working alongside its project partners to create opportunities for local communities, landowners, parish councils and schools to get involved via volunteer days, habitat management and creation workshops, wildlife gardening and species monitoring. The project is currently in its development phase and is focused on public consultation and species and habitat monitoring – this work will help to secure funding for the next phase of the project.

NHBS conservation volunteering day

My role as a volunteer is to undertake surveys throughout the flight season of both the Long-horned Bee and its cuckoo between May and July and record the number of individuals seen along this stretch of coast, with a particular focus on known nest aggregation sites and the coastal path between Gara Rock and Mattiscombe Sands. The survey consists of slowly walking along the coastal path, stopping to count Long-horned Bees when I see them. I record the number of males and females, the location/grid reference, and any extra information that may be useful, such as the plants that they are feeding on.

It was wonderful to see so many Long-horned Bees foraging along the cliff top throughout the day. As mentioned above, they tend to favour plants such as Bird’s-foot-trefoil, clovers, Narrow-leaved Everlasting-pea, brambles and Kidney Vetch, and there are sections of the coastal path where these can be found in abundance. Unfortunately, these plentiful patches are in short supply, and Buglife hopes to identify the key areas for habitat enhancement to support the population of Long-horned Bees, which will in turn benefit the Six-banded Nomad Bee.

The highlight of the day was watching one nest aggregation in particular, a site that we have become quite familiar with over the years. It is always a bustling hub of activity and is primarily where the Six-banded Nomad Bee has been recorded in the past. Female Long-horned Bees were repeatedly flitting in and out of the nest entrance holes, with the occasional male patrolling the nest entrances in search of a mate. Sadly, I did not see the Six-banded Nomad Bees this time but was pleased to count a total of 75 Long-horned Bee sightings throughout the day.

I have been involved in monitoring this site since 2017 and so it was wonderful to have the support of NHBS to spend some time at Prawle Point to contribute to this year’s records. It is vital that monitoring along this stretch of coastline continues, especially as our records of the Six-banded Nomad Bee are so few.
