NHBS manufacturing – a year in review

2023 proved to be a pivotal year for the NHBS manufacturing team, one in which we enjoyed new and continued partnerships with key organisations, overhauled the NHBS Harp Trap with the aid of leading UK ecologists, and continued to refine our existing products. 

A glimpse into the manufacturing workshop at the NHBS offices in Totnes, Devon.

Fine tuning the NHBS Moth Trap 

Since its introduction in late 2019, the NHBS Moth Trap has been a consistent favourite with hobbyists and professionals alike. However, a manufacturing team consistently motivated to improve our products and with an ear to the ground for customer feedback resulted in an evolution of the trap in 2023. The new design is more robust, lighter and more cost-effective.  

By changing the design of the lamp support, our manufacturing team were able to reduce the amount of steel used, saving on both weight and cost. We also upgraded the material used for the moth trap panels to a more rigid and environmentally friendly material, constructed from 70% recycled plastic. Finally, our team developed a system that allows the NHBS Moth Trap to run off a 12V battery using an inverter kit. A full night’s trapping is now possible using a single battery. 

The NHBS Moth Trap was designed in consultation with Butterfly Conservation. NHBS is proud to support the excellent work they carry out with each sale of the trap.

Nets for every occasion 

There is a sense of pride in the development of the iconic orange banded nets that NHBS produce. Without knowing it, you may have seen them in action on prime-time television shows including Springwatch and the BBC flagship series Earth that featured Chris Packham using an NHBS plankton net in the first episode.  

Our bestselling Professional Hand Net also forms a key part of the Riverfly Partnership approved survey kit. Our relationship with the Riverfly Partnership dates back to when NHBS originally acquired EFE & GB Nets in 2016, and we are pleased to further support the Partnership by making a donation to them with each sale of the kit. You can find out more about the great work the Riverfly Partnership are doing in our previous blog and on their website. 

Conservation research and monitoring 

At NHBS we are experienced in working with our customers to either develop or improve equipment for use in monitoring wildlife. Where necessary we seek out experts who can examine the design of the product and give feedback on improvements; not only to meet project requirements, but also to ensure the design is sympathetic to the wildlife that are subject to the equipment’s use.  

Early in 2023, we wanted to overhaul our Three Bank Harp Trap and so reached out to respected and experienced ecologist Neil Middleton of Batability. Neil and his team gave crucial feedback on the trap’s existing design and highlighted areas where improvements could be made. This allowed our manufacturing team to refine the design so that it maximised the safety of the bats that were caught, as well as making it easier for ecologists to use. By listening to the experts and users and making their recommended changes to the design, we now have a product that we are exceptionally proud of. 

A visiting team from LIST collaborate with NHBS engineers on the exciting NEWTCAM project.

NHBS manufacturing in 2024 

This year promises to be full of exciting developments, including the NEWTCAM project that NHBS is working on in collaboration with the Luxembourg Institute of Science and Technology (LIST).  As well as providing a novel approach to monitoring amphibians, NEWTCAM represents a very different type of technology for our manufacturing team, giving them a chance to learn valuable skills which can be utilised in future products. The first units are currently in production and will be made available to early users for field testing from spring 2024. 

At NHBS we are committed to finding the best materials and are constantly working to improve the sustainability of the production methods we use. If you have a project or product you think we could help with, please do not hesitate to get in touch using our contact form.

This week in biodiversity news – 5th February 2024

Climate crisis

The UK has approved 24 new North Sea oil and gas licenses in the face of significant criticism. The move angered many environmental campaigners and MPs who labelled the decision as “grossly irresponsible”. The government defended the move stating that the oil would be imported from overseas if it wasn’t extracted from the North Sea. Environmentalists have argued that granting the licenses will do relatively little to improve the UK’s energy security and undermines Britain’s move towards net zero emissions.

Conservation

The National Trust has committed to recreating lost rainforests by planting 100,000 trees in North Devon. Temperate rainforests once covered vast swathes of western Britain, but the rare habitat declined due to historic deforestation and continues to face threats from air pollution, invasive species and diseases. It is now one of the most endangered habitats in the UK covering only 1% of Britain’s landmass mostly in Cumbria, Devon, Cornwall, North and West Wales and the West of Scotland. Exceptionally heavy rainfall and high humidity levels allow moisture-loving plants like mosses and lichens to thrive in these areas and the restored rainforest will be a haven for rare specialist plants that depend on this habitat.

Environment

Toxic run-off from roads has been found not to be monitored, according to the BBC. Rivers close to major roads have been tested by campaigners and have been found to contain a cocktail of chemicals and particles from the roads. National Highways has a statutory responsibility to make sure that discharges from its network do not cause pollution and the Environment Agency is responsible for monitoring water pollution in England. However, in response to a freedom of information request, the agency said that it did not regularly monitory run-off. Oil, chemicals and wear from tyres are washed down drains in heavy rain and subsequently flow into rivers and streams causing damage to sensitive aquatic ecosystems.

The government remains largely off track to meet its environmental targets, according to the Office for Environmental Protection (OEP). The OEP’s annual progress report concludes that while some progress has been made, the government is largely off track to meet both targets and legal obligations and that the government must speed up its efforts and implement policies quickly to bridge the gap.

Extinction risk

The Greater Glider is on course for extinction due to a controversial decision by the Australia’s New South Wales environmental watchdog, according to experts. The Environment Protection Authority (EPA) told stakeholders that it was scrapping measures that required a government-owned forestry corporation to search for Glider dens which currently have to be given a 50-metre logging exclusion zone. Experts have told the EPA in no uncertain terms that they are effectively locking in the Glider’s extinction. Greater Gliders rely on between six and 20 den trees for its habitat which is already under significant pressure due to summer bushfires and logging activity.

Science and discoveries

A new map has revealed that England’s hedges would wrap around the Earth ten times if lined up end to end. The map is the most comprehensive to date revealing a total of 390,000 km of hedgerows. Researchers from the Centre for Ecology and Hydrology used Lidar (Light Detection and Ranging) remote sensing data. They found that the South West of England boasted the largest share of hedges accounting for 24% of England’s total with Cornwall leading at the county level. Around half of Britain’s hedges were lost in the post-war period, and while losses have slowed since the 1990s, major threats to Britain’s hedgerows remain.

The birth of a Great White Shark may have been captured on video for the first time. Wildlife filmmaker Carlos Gauna and UC Riverside biology doctoral student Phillip Sternes were filming California’s coastal waters with their drone when they spotted something unusual. By enlarging the images from their video footage and putting it in slow motion, they realised a white layer was being shed from the body of a shark. They believe it was a newborn white shark shedding its embryonic layer.

The Big Garden Birdwatch: NHBS Staff Results 2024

The RSPB’s 45th Big Garden Birdwatch took place between Friday 26th and Sunday 28th January 2024. This annual event is one of the largest citizen science wildlife surveys in the UK and helps us gain an understanding of how our garden bird populations are changing in abundance and distribution over time.  Over half a million people took part in last year’s event, recording a total of 9.1 million birds. House Sparrows took first place, despite a gradual 57% decrease in sightings since the first Birdwatch Count in 1979. They were closely followed by the Blue Tit and Starling. 

Although the Big Garden Birdwatch has finished, there is still time to submit your results on the RSPB website by the 18th February, or by post before the 13th February. Even if you didn’t see anything, it still counts! 

With birds being faced with an increasing number of challenges each year, it’s more important than ever to make your garden and outdoor space wildlife friendly. This can include installing bird feeders or tables which provide an important food source throughout the winter months when natural food sources are scarce., You can also provide clean, fresh drinking water in shallow containers such as bird baths or saucers, and install nest boxes for breeding in the spring. Also, don’t forget to regularly clean and maintain your feeders and baths as this helps stop the spread of disease. Head over to the RSPB website to find out more about how you can help your garden birds.

Meet the new Song Meter 2 ultrasonic and acoustic recorders

Wildlife Acoustics are renowned for their attention to customer feedback which they use to refine their products and ensure they are of the highest quality.  It also means their products are some of the easiest and most flexible to use which makes them favourites with researchers around the world.

The latest additions to their range are the second-generation Song Meter Mini 2, Mini Bat 2 and Micro 2. In this blog you’ll find out exactly what’s new in these improved models and which of the original excellent features have been retained.

What’s new?

Increased battery life

• The Mini 2 with AA batteries will now record for up to 625 hours (when using 8 x AA batteries). This is more than twice the amount of the original Song Meter Mini.

• The Mini 2 with Lithium-ion batteries offers up to an incredible 1,565 hours of recording time, making it ideal for use in difficult to access locations.

• The Micro 2 will now record for up to 240 hours with just 4 x AA batteries – a huge 33% increase over the original Micro.

 

Improved weatherproofing

All Song Meter units are now tested to IP67 standards. This means that, not only are they protected against typical weather conditions, they can also be dropped into water up to a meter deep for 30 minutes without any water ingress. Perfect for the toughest conditions in the field.

New hinged enclosure

The casing has been completely redesigned so that the lid is hinged to the body and opens using a simple latched mechanism. With purposely designed holes to fit cable locks and/or padlocks, you can leave your equipment unattended, safe in the knowledge that your recorder is secure and cannot be accessed by anyone else.

New tripod mount

Further flexibility in siting has been achieved by the addition of a standard tripod mount. The Mini 2 and Micro 2 can now be quickly and easily attached to any item that has a standard tripod connector.

What has stayed the same?

All the Song Meter second-generation recorders still include a low-noise microphone that produces high-quality sound files. The same companion app, available for iOS and Android, is used to programme the recorders, ensuring that you can quickly and easily update them with your existing recording schedules. Finally, all recorders come with the same 2-year warranty, offering you peace of mind when you buy.

FEATURING

The Cry Wolf Project: Bioacoustics & Carnivores in Yellowstone National Park

Come and learn about how bioacoustics are being used to study wolf vocalisations in the remote and often wintery locations of Yellowstone National Park. We’ll cover the use of wildlife recorders for studying the function of wolf vocalisations, generating population estimates, and mediating wildlife-livestock conflicts. We’ll also demonstrate how Kaleidoscope Pro classifiers were used to find wolf vocalisations in large recording datasets. Most importantly, we’ll have fun listening to never-before-heard wild wolf sounds, recorded non-invasively in 2023.

Un Suono in Estinzione (A Sound in Extinction) – Adamello Glacier, Italian Alps

Hear the results of an experimental research project aimed at monitoring the implications of climate change on Alpine glaciers through the analysis of sound expressed in educational, artistic, and scientific activities. Un Suono in Estinzione (A Sound in Extinction) began in 2020 with researcher and sound artist Sergio Maggioni, around whom a team of professionals from different fields was created in a short time. Learn about the results of this fascinating bioacoustics project and its inspiration.

Acoustic Sensory Ecology of Diving Alcid Seabirds & Potential Noise Impacts

Alcid seabirds like the Atlantic Puffin are important components of holarctic coastal ecosystems and may derive important acoustic cues from the surrounding natural soundscape. As people increasingly utilise Arctic coastal areas, it is essential to characterise these soundscapes as a baseline for understanding seabird acoustic biology so that we can quantify the effects of human activity on their acoustic ecology over time. Learn how passive acoustic monitoring was used to document and describe the aerial soundscape dynamics of puffins and other Alcids seabirds such as Common Murres and Marbled Murrelets, and explore how these soundscapes may be related to their acoustic sensory biology.

Author Q&A with Derek Gow: Hunt for the Shadow Wolf

Renowned rewilder Derek Gow has a dream: that one day we will see the return of the wolf to Britain. As Derek worked to reintroduce the beaver, he began to hear stories of the wolf. With increasing curiosity, Derek started to piece together fragments of information, stories and artefacts to reveal a shadowy creature that first walked proud through these lands and then was hunted to extinction as coexistence turned to fear, hatred and domination.

With bitingly funny but also tender stories, Hunt for the Shadow Wolf is Derek’s quest to uncover the true nature of this creature because, as we seek to heal our landscape, we must reconcile our relationship with it. Before we can even begin to bring the wolf back, we need to understand it.

Derek recently took time out of his busy schedule to talk to us about Hunt for the Shadow Wolf, including how his fascination with the wolf began, what role it could play in Britain’s landscape and more.


As well as being packed with personal stories and fascinating snippets of wolf biology and behaviour, Hunt for the Shadow Wolf is an incredibly well-researched history of the wolf, told through the myths and legends that abound throughout our lands. How and when did your fascination with the wolf and its history in Britain begin? 

Hunt for the Shadow Wolf Chapter 3 sketch. if a wolf baring its teeth in a graveyard.

My personal interest in the wolf story began early. I remember quite clearly my grandmother, who was a slight, erect, sprightly soul, telling both myself and my bored brother on a long car journey to Dundee the story about a place called wolf clyde which was near to where we lived in the Scottish borders at that time where the last wolf in Scotland was killed. It was just nonsense about a woman with children being attacked by the wolf which she brained in response with a pancake griddle, but nevertheless it began a slow smoking interest in the old myths which given the opportunity I was keen to explore further.  

Why do you think that an understanding of the historical culture, myths and legends surrounding a species has relevance to its conservation and role in our ecosystems today? 

A factual understanding of the history of this much maligned species in Britain is very important as the lies we made up in the darkness of our ignorance to try to twist the cultural character of the wolf into one of loathing and repulsion still sway the responses of a phenomenal number of individuals and organisations to this day. Despite the very best of our advanced understandings of what wolves are and what they do, this toxic taint is still bubbling strongly.  

Hunt for the Shadow Wolf Chapter 6 sketch of a wolf baring its teeth at a woman who has a sword in her hand and is trying to protect her sheep from an attack.Even in children’s tales, the wolf invariably represents a character of fear, violence and threat. Do you think these types of stories have a significant role to play in the development of our feelings towards wolves as adults? 

Absolutely as they reflect only the darkness in the minds of the adults who wrote them and by so doing chose to corrupt a bad reputation without thinking into an even darker evil to infect the minds of the young. Nowadays it’s gratifying to see in so many good environmental centres throughout Europe, within the wolves expanding range, more understanding and compassionate explanations about both their history and the reality of living with them.

Britain is in a unique position compared to mainland Europe in that wolves will never be able to repopulate of their own accord. Do you think that a reintroduction project will ever occur, and what are the key challenges that stand in its way? 

I think we should reintroduce the wolf and prepare the way for even more of our lost beasts. Farming has had it all its own way without balance of any sort. If a species gets in our way, we kill it. It’s what we are doing to badgers right now. In the past we inflicted so much heartbreakingly visible cruelty. Now, we destroy on a scale that’s colossal without thinking about the smallest of creatures and those tinier still that inhabit the soil. It’s a viciously unnecessary process.

What role do you think the wolf could have in healing the landscapes of our currently denuded Britain? 

I think they would both move deer considerably and by doing so disrupt their grazing patterns for the betterment of forest understory regeneration. I think they would make those that keep sheep consider their worth and then, if these animals are of value, protect them better. I think their very presence, wild but unthreatening, would more than that of any other creature enable all of us now living on this island to establish, if we wished to do so, our relationship with the natural world.  

As well as travelling widely to locations where wolves live in the wild, you have also had the incredible experience of hand-rearing wolves in a wildlife centre. What is your most memorable first-hand experience with a wolf or wolf pack? 

Naida, one of my tame cubs, ate my car keys. I only had one set and had to wait for what seemed an eternity for them to pass through her before picking my way through her enormous turds to get them back.

Lots of things. The last of bits of farming feeding my cows. Dog walks and avoiding the rain. Trying to develop a foundation to help us breed even more threatened British species for reintroductions. And books? Well, on long dark evenings I have been researching the intriguing history of the European Bison. not the bits of sadness that brought the species to its knees in the early 20th century, but the complicated individuals who for a time held its future in the palms of their hands. Great characters like the 11th Duke of Bedford, who assembled breeding herds of threatened species on his Woburn estate, and tyrants like Hermann Goering, who used slave labour to create vast parks within which he hunted. It’s an intriguing slant that’s little known but it saved the species for a time when the world for them has become a better place where they can roam in peace, a range that is vast. There might be a book in that!!

Supplier interview with Fran Tattersall from Wildlife Acoustics

Wildlife Acoustics creates world leading wildlife acoustic monitoring tools, specially designed to help scientists make impactful discoveries that expand our understanding of this biologically diverse planet.

A passionate and innovative group of technologists, operational experts, wildlife enthusiasts and conservationists, they have a zeal for helping their customers succeed in their research —understanding their needs and creating wildlife audio recording and analysis tools specially designed to help them conduct research across the globe.

We recently chatted with Fran Tattersall about the history of the company, their latest products, and the incredible ways that they are enabling researchers to collect vital data.

Fran works as the European Business Development Consultant for Wildlife Acoustics and is passionate about the environment and conservation. She is incredibly knowledgeable about the company and their products, and we were grateful to her for taking time out of her busy schedule to answer our questions.


Could you tell us about the history of Wildlife Acoustics? What inspired its creation?

Wildlife Acoustics was founded by Ian Agranat, an engineer, technologist, and nature enthusiast who is still the company’s CEO.

On a family hike in the early 2000s, Ian’s brother-in-law wondered aloud about creating a device for recording and identifying birds by their songs. Wildlife Acoustics’ first product, Song Sleuth, was launched shortly thereafter. Long before we were familiar with such tools, Song Sleuth used AI to identify North American bird species by their calls!

The US Geological Service was intrigued by the possibilities and asked Ian to develop a reliable, programmable recorder and software to help identify bird calls. This led to the invention of the Song Meter SM1, the first commercially available, built-for-purpose acoustic wildlife recorder, and the Song Scope software. Biologists now had a fully integrated, cost-effective, weatherproof solution for monitoring and analyzing the vocalizations of birds, amphibians, and terrestrial animals. (The first SM1 is still in the field today!)

Can you tell us more about the people that use Wildlife Acoustics’ products and what they use them for?

We have products for anyone who wants to record vocal wildlife, bats, or soundscapes!

Our recorders and sound analysis software are used for research projects at universities and NGOs around the world. For example, Bat Conservation International used a Song Meter SM4BAT-FS to re-discover the Hills Horseshoe bat in Rwanda—an endemic species once thought to be extirpated.

Song Meter recorders are also used by ecological consultancies working on everything from large infrastructure projects, such as HS2 and wind farms, to individual householders replacing their roofs.

Our Echo Meter Touch 2 bat detector, which allows people to use their Android devices to hear bats echolocating in real time, has been particularly popular with the general public and is a great engagement tool on bat walks. More recently, our Song Meter Micro has gained popularity with birders who want to record nocturnal migration flyovers.

What are some of the most interesting ways you have seen Wildlife Acoustics’ products being used?

In February, we will be hosting a webinar on the use of our recorders in cold places, and one of the speakers is monitoring glaciers with a Song Meter SM4. I’m looking forward to learning more about that!

More usually our recorders are listening to wildlife. Mammals are my personal favourite species group. We have people recording Maned Wolves, Manatees, elephants, Okapi, moose, Rock Hyrax, and many more.

Interestingly, it’s not just bats that use ultrasound to communicate. Our “bat” recorders have been instrumental in finding and monitoring the invasive White-toothed Shrew in northeast England and discovering that Indonesian Slow Loris use ultrasound to avoid predators. We even have a customer who records lab rats “laughing” when tickled.

Our customers are always finding fascinating new ways to use our equipment!

The new Song Meter Mini 2 and Song Meter Micro 2 are due to be launched soon. How do the new versions compare to their predecessors?

We’ve listened to customer feedback and improved the enclosure, extended battery life even further, created separate AA and Li-ion versions (18650 batteries) for the Mini 2 and the Mini Bat 2, and added a quarter-inch, 20-thread-per-inch tripod mount.

The ergonomics of the closure mechanism have been improved, using a hinged lid that can be secured with a simple cable lock. No more having to keep track of a separate lid. And the whole thing is now IP67-rated and built to withstand even the most rugged terrestrial deployments.

AA battery life has been significantly improved thanks to a larger battery tray that doubles the capacity from four to eight batteries. So for a Mini Bat 2, that means up to fifty 10-hour nights of recording, and for a Mini 2, it’s 420 hours of acoustic recording! (And best of all, the price of the AA versions remains the same.)

On the Micro 2, in addition to housing improvements, we improved the design by making room for an additional AA battery, which extends recording time by 33 percent.

Which of the new products is your favourite and why?

I enjoy exploring the new science of acoustic indices and soundscape analysis and am looking forward to using the Song Meter Micro 2, which has a flatter frequency response than its predecessor, making it eminently suitable for this type of work.

It’s also a great little device to take on wildlife holidays because it is so small—perfect for recording dawn choruses, nocturnal soundscapes, and finding that elusive bird. It’s always exciting to look at the contents of your SD card in the morning and hear what’s been around!

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

Only that we’re not resting on our laurels. Our engineers are working on new ideas all the time, and NHBS will be the first to know when we’re ready to make announcements!


All of Wildlife Acoustics’ products are available at nhbs.com. For more information or advice tailored to your specific requirements, please contact us and speak with one of our technical advisors.

This week in biodiversity news – 15th January 2024

Extinction

A recent study has found that humans have wiped out double the number of bird species as previously thought. According to the Centre for Ecology and Hydrology (UKCEH), 1,400 bird species have been made extinct which amounts to 12 percent of species being lost due to modern humans. The causes of the destruction of so many species include habitat loss, overexploitation and the introduction of species which have competed with native species and hunted them as prey. The loss of so many bird species is likely to have had harmful effects on ecosystems due to their key functions such as seed dispersal and pollination and because of the range of other species that depended on them for survival.

The mystery of the extinction of the largest ever primate has finally been solved. Until recently, the extinction of Gigantopithecus blacki, a giant three-meter tall 250-kilogram primate that lived in the plains of southern China, was a mystery. A large study by a team of researchers from China, the US and Australia of 22 caves in China found that the species on the brink of extinction between 295,000 and 215,000 years ago struggled to adapt to its changing environment. While other primates such as the orangutan adapted their eating habits and behaviours in response to this change, Gigantopithecus blacki struggled to adapt, and as a consequence went extinct.

Biodiversity at risk

The Nigerian Government has destroyed £7 million worth of elephant ivory. The stock of elephant tusks was one of the largest ever seized in Nigeria and weighed close to 2.5 tonnes. Tens of thousands of elephants are killed worldwide each year for their tusks which are often carved into highly valuable works of art. It is estimated that fewer than 500,000 elephants persist in Africa, a considerable decline from 1.3 million in the 1970s. The destroyed ivory will be pulverised into powder which will be made into a monument symbolising the importance of elephant conservation in Nigeria.

Norway is set to approve deep-sea mining operations despite major environmental concerns. The move will make Norway the first country in the world to open up its seabed for deep-sea mining. Scientists have voiced considerable concern over the potential impact on marine life and carbon storage. Recent studies in Norwegian waters have shown that mining operations would have severe impacts on unique marine wildlife. The EU and the UK have opposed such a move citing environmental concerns. Norway has claimed that exploiting deep-sea mineral deposits will aid the green transition.

Climate crisis

Scientists have confirmed that 2023 was the hottest year on record. Last year saw temperatures 1.48°C warmer than the long-term pre-industrial average temperature. The record high has been driven by a combination of human-caused climate change and the natural El Niño weather phenomenon. The latter half of 2023 saw temperature records for the time of year being broken almost every day with a worrying increase above previous records. 2023 was also notable for extreme glacial retreat, Antarctic sea-ice lows and record ocean temperature highs which far exceeded previous records.

Germany’s greenhouse gas emissions hit a 70-year low in 2023, according to a German think tank. The low comes as Germany winds down its coal-fired power production resulting in a reduction of 73 tonnes of greenhouse gas emissions this year. This was made possible by reduced overall electricity demands and increased foreign imports from renewable energy sources. However, the study also highlighted that only 15% of the total can be counted as permanent emission reductions with a large proportion due to unpredictable social or economic activity.

Farmers have called for stronger river defences after Storm Henk wreaked havoc on their crop fields. Many thousands of acres of agricultural land have been left sitting under water in the wake of the storm which follows Storm Babet and Ciaran in the autumn. The National Farmers Union has also called for compensation for farmers who are directed to let their fields flood as part of efforts to protect towns from flooding. The extreme flooding has caused significant financial stress for many affected farmers. The government has said that £221 million was being spent on flood defence maintenance in 2023/2024.

Scientific discoveries

Sperm Whales live in culturally distinct units, a new study has revealed. Scientists at Dalhousie University, Canada, analysed Sperm Whale feeding habits and the sounds they made using underwater microphones and drone surveys and found that they organised themselves into female-based groups of up to 20,000 animals. These groups were divided by distinctive sequences of clicks in their vocalisations. The researchers discovered that while different clans of the whales might meet, they never interbreed, recognising and maintaining their differences.

 

Author interview with Edward Bent: Plant-Life: A Walk with Nature

Plant-Life book cover showing a photograph of a pair of brown boots stood on a grassy path with a red poppy in the left hand bootThis adventurous and versatile book explores the wonders of our relationship with plants and our involvement with nature. Full of information on botanical science, ecological and environmental factors, artistic appreciation and philosophical reflection, Plant-Life offers a more holistic view of nature than in other books within this field. The text is supported by detailed images, diagrams and tables which provide a framework of understanding for the critical and questioning mind needed to approach biodiversity and climate change. 

Edward Bent, author of Plant-Life, stood wearing a red jumper holding his book.

Author Edward Bents career was founded on a Botany degree from the University of Hull, followed by many years of experience spent working across different sectors, including research, marketing and education. After moving to Italy, he became a self-employed consultant and writer with many of his articles published in leading international publications, as well as a founding director of UK plant breeding company Floranova Ltd. While producing a series of botanical art compositions exploring spatial relationships in plant communities, Edward was inspired to research and write this book as a way of reflecting on his understanding of plants and the ways of nature. 

Edward recently took the time out of his busy schedule to talk to us about the inspiration behind his book, why he chose to write in a journalistic style, other projects hes currently working on, and more.


In the first chapter it says that you have always wanted to explore the beauty of plants and flowers and to share an appreciation of their world with others. How did you first develop this fascination and love of botany?

From an early age I liked to draw and paint plants and flowers to express an artistic temperament and reveal what I thought to be aesthetically pleasing. This extended to outdoor landscapes. At secondary school, I studied botany at ‘O’ and ‘A’ levels, followed by a degree course at University. During these scientific studies, significant periods of practical work allowed greater awareness of the beauty of plants and flowers and led me to make drawings. This same awareness continued through research and teaching, in parallel with a scientific frame of mind. I refer later to the influence of realising botanical compositions of wildflower communities while retaining a botanical coherence.

A dichotomous key was one of the first methods used to identify different plant species and variants through a hand lens before pictorial guides were developed. How do you think this early identification technique has affected the ways in which we observe and identify plants in the present day?

Pictorial guides to identify plant species represent a very useful shortcut, but, in many cases, just a few characteristics such as flower type, colour and leaf shape are sufficient to get the answer. While most guides also carry some detailed written descriptions, this is not commonly referred to except for professional reasons or uncertainty. The methodology of using a dichotomous key not only requires more time, but also attentive observation of far more plant characteristics. This helps develop powers of observation, or a trained eye, and better understanding of taxonomy, while providing an enjoyable sense of investigation. I believe that pictorial guides were developed to speed up the process of identification and to provide ordinary people, not just botanists, with an easier-to-use instrument.

I really enjoyed how Plant-Life touched on the relationship between botany and other disciplines such as art, poetry, maths and bio-economics. What inspired you to investigate these relationships throughout the book?

Firstly, reading Keith Critchlow’s book (see my answer to your question six), but also because of the impressions perceived of the beauty of spatial relationships in natural plant communities, through observation and realising the botanical compositions from pressed plant material. The aspect of bio-economics relates to the common denominator of chaos and complexity. Some years ago, I had also written another book that had prepared my mind to be more receptive to these relationships, and gave rise to my logo/trademark WOWWalk on the Wild side.

When walking in the country, I always sought the big picture, since nature – of which we are part – is more than just the science. The concept of ‘Art of nature and Nature of art’ also came through in my research, strengthening the wish to break down perceived barriers between science, art and indeed philosophy. Scientific methodology works through separation, not only between different disciplines but also within them, while an examination of nature demands a more holistic approach.

What inspired you to write in a holistic, journalistic style rather than the more traditional, academic style that many ecology books demonstrate?

I think a holistic style is essential to understanding the ways of nature. It involved a strong desire to engage in artistic appreciation and philosophical/spiritual reflection on the perceived beauty of plants and wildflowers in their natural habitats. That is something I have, as long as I can remember, ‘taken aboard’ with a mixture of interest, observation and empathy. The artwork involved in the realisation of a series of botanical compositions also inspired the book and gave rise to logo, N-ART-URA The Culture of Biodiversity.

A journalistic style in communicating information in straightforward language was obligatory after analysing big data scientific papers, news releases, books etc to make the writing more accessible to a wider and multi-level readership. This mission and ability stems from teaching and years of writing feature articles for the horticultural trade press and a few books. Equally, easier, pre-digested science would be unable to deal with some of the concepts and information presented in my book.

Do you think our plant life will reach a point where species will consistently be able to adapt to, and thrive within, the ever-changing environment that human activities have created? 

Much depends on the timeframe. Our destruction of ecosystems can be total or partial (leaving intact corridors) and usually happens very quickly, whereas the process of plant adaptation is gradual and long drawn out. The protection and conservation of large areas of wilderness are fundamental to securing the absence of damaging human activities. Despite this, nature is programmed to fill any ecological voids that occur.

The so-called ‘generalist’ plant species adapt far more quickly to new environmental challenges, as opposed to more specialist species adapted to precise habitats, such as alpine flora . The latter have a much smaller gene pool when needing to adapt to new conditions, rendering them more vulnerable to extinction. So, the generalist species will adapt more quicky and spread more widely throughout areas of ecological disruption and damage caused by human activity.

Species distributions will become increasingly alike between different geographical areas and continents, caused by human activities travel and transport, for example. There will be new opportunities for hybridisation, mutation and a few new species or sub-species. In a few cases, plant breeding and genetic manipulation in agricultural and horticultural crops, can ‘escape’, potentially affecting wild species from which crops were developed.

How did you develop your Holistic Notion diagram and what can this teach us about the relationship between nature and human emotions? 

This diagram is central to my book and needs further development. The publication The Hidden Geometry of Nature (Floris Books) by the late Keith Critchlow was inspirational and highly informative in providing links to further thought and research. I highly recommend this important book to students and teachers of botany to give the subject a wider context.

The human mind reasons and analyses, whereas the human heart brings natural phenomena together, connecting with natural beauty; something that is impracticable in scientific study, because scientific methodology invariably needs to be separate. The Holistic Notion diagram seeks to present mathematical principles lying behind nature and the universe that translate to specific aspects of ‘being’, the substance of what we are and what we see. In holism, emotions and intuition are as important as the science in terms of understanding. Emotions stem from our interest and perception of form and substance, engendering a feeling of continuity and gratitude.

You briefly touched on the role of computers and artificial intelligence in creating ecological models that can be used to analyse data and potentially assist in the recovery of our environment. How important do you think these technologies will be in this process? 

I believe that artificial intelligence and computer power will be very important in realising ecological models because of the huge amount of data and number of variables involved. What is less certain is the success of these instruments in terms of conservation or rewilding, because the whole picture can never be pinned down to one moment in time. Plant-life and nature are in constant evolution, even more so with the dramatic effects of climate change. I define nature as working through dynamic instability, choosing complementary interdependence as the means. So, recovery will depend on the progressive ‘load’ of environmental challenges on plant communities, the biosphere and the Earth system itself, caused by climate change. Just how can artificial intelligence predict these events?

Do you have any current projects in progress that you can share with us? 
I am seeking ways to complete my NARTURA project by printing and publishing a series of nine botanical compositions, because earlier samples were well-received and complement the book. It requires, a printer, marketing, and distribution located in the UK. Living in Italy makes this more difficult, although I do have digital samples and plenty of ideas.
