NHBS In the Field – Motic SMZ-140

There is something wonderful about microscopy – the examination of tiny insects and fungal spores feels like peering into another world that we seldom have the privilege to observe. For some naturalists, a stereo microscope might seem like an unnecessary extravagance but for many who work with tiny subjects like invertebrates, lichenous fruiting bodies or bryophyte spores they can shed a light on fascinating diagnostic features that a hand lens simply doesn’t have the power to show.

We have recently added the Motic SMZ-140 and -161 series to NHBS’s range of stereo microscopes. Known for their good quality, robust entry-level optics as well as their laboratory standard equipment, Motic Europe has an excellent reputation among industry professionals and hobbyists alike. As such, we were excited to have a look at their mid-range LED model, the SMZ-140-LED. Designed to be as flexible as possible, this series has the advantage of a very wide 10x-40x magnification range, rather than the 20x-40x that most stereomicroscopes offer in this price range, as well as reflected and transmitted LED illumination and fully modular design for further customisation.

How We Tested

The SMZ-140 was tested thoroughly with a variety of different subjects. Specimens used originated from an invertebrate monitoring program close to our South Devon office, along with a variety of botanical subjects selected to test the microscope’s use in different disciplines. The image clarity and brightness across its zoom range were noted, as well as our impressions of the mechanical systems such as zoom, movement focus. The different accessories such as stage plates and options like lighting methods were also used to get as complete a picture of the systems’ utility across as complete a range of applications as possible.

What We Found

First Impressions

The first thing that is apparent about the SMZ-140 is the compact design and packaging. The box that it is supplied in manages to be easily a quarter the size of other models of a similar price and specification, and noticeably lighter too, without sacrificing any protection. This is because the microscope itself is remarkably compact, the base built to centre the weight on a smaller footprint than any other I have seen. This makes a real difference when workspace is limited, or if there is a chance that the microscope might need to be moved to different venues. It is supplied with the head detached from the body but setting it up is a simple and intuitive process that takes no more than a few minutes. Comprehensive instructions are also supplied.

The look of the SMZ-140 is simple but professional. The positioning of the zoom and focusing wheels is intuitive, and both move smoothly without resistance or kick back. The supplied stage plates, one reversible black/white plate for use with the reflected illumination system and one translucent plate to complement the transmitted illumination option, are also robust and resistant to scratching. One slight drawback is the lack of any lens caps, but good-quality dust cover is supplied to protect the workings from any ingress.

The working distance, that is the distance between the head and the staging platform, is 80mm, which allows for easy manipulation of the subject, including dissection where appropriate. The pinions should be sufficient to hold most subjects in place and have an impressive range of movement for use with larger samples.

Eyepieces and Illumination

The eyepieces are comfortable to use, padded with rubber and with an adjustable interpupillary distance. Each one has a +/- 5 diopter adjustment, allowing for easy adjustment to the user’s eyes. The whole head piece can be moved from side to side at the user’s convenience. The zoom wheel moves easily and is mounted on the head, while the larger focusing wheel is placed on the pillar to minimize confusion between the two while the user is looking through the eyepieces.

The standard 10x eyepieces that come supplied with this model can be swapped out for 15x, 20x, or 30x options, and the 1-4x objective lens can be removed and replaced with lower magnification options such as 0.5 times as desired.

The illumination is bright and can be adjusted at will, allowing for the user to adjust it if they find themselves dazzled or if working with a reflective subject such as a beetle that risks being washed out by a powerful light source. The transmitted and reflected options are activated via separate switches, meaning that both could be used simultaneously if so desired.

The LED bulbs on this model are of use to many researchers as they provide heat-free illumination and will therefore not damage live specimens or dry out those that are at risk of desiccation, such as insects or lichen.

Magnification and Image Quality

In contrast to the standard 20x-40x zoom of most stereomicroscopes in this price range, the SMZ-140 has a range of 10x-40x. As previously stated, this can be increased up to 120x with 30x eyepieces, but for the vast majority of applications the standard range should be perfectly adequate.

The low minimum zoom makes the microscope very useful for larger specimens or jobs that require a wider field of view such as mounting medium sized insects. Motic’s lenses provide a clear, crisp, and bright image even up to the maximum magnification of 40x. The user might struggle with the diagnostic features of very tiny subjects, i.e. those below 1mm, but for the price range the image of the SMZ-140 is among the best I have seen. The keystone effect is noticeable with this model, as it is in most Greenough system stereo microscopes, but is barely perceptible next to the natural variation in focus of three-dimensional samples.

The 20x and 30x click stop feature of the zoom wheel is very useful when working at higher zoom levels, as it allows the user to standardize the magnification at which specimens are examined and makes accurate record keeping easy. The magnification is also indicated on the wheel for visual reference.

Our Opinion

With the SMZ-140-LED, Motic establish themselves as manufacturers of excellent, affordably priced stereo microscopes ideal for almost any use that a naturalist could desire. Among a crowded market of models with very similar specifications, it distinguishes itself through its compact, lightweight design, robust build, and wide zoom range. It is easy to use and provides consistently excellent results, and the modularity of its design along with a good range of accessories allows for simple adaptation to a wide array of jobs.

While some microscopists might prefer to look at more expensive models with wider lens apertures for an even brighter image (such as the SMZ-160 series), or even high-end models that utilize the advanced common mains objective optical system, among models in its price range the 140 certainly stands out. It’s clear that it is designed with flexibility in mind, and as such it is an ideal choice for anyone looking to dive a little deeper into the wonderful world of the tiny.

Seabirds, and a Short History of Illustrated Bird Guides

Seabirds by Peter Harrison, Martin Perrow and Hans Larsson represents the latest in a long history of exquisitely illustrated bird identification guides. An update of the original 1983 publication of Harrison’s, it covers all 437 known species of seabird, from seaducks and grebes to cormorants and pelicans. The publication of this beautiful and comprehensive book has prompted us to take a look at some of the history surrounding illustrated bird guides over the past century.

Title page of the History of the Birds of Europe

At the end of the 19th century, there existed only a few professional bird illustrators. These were usually employed by wealthy patrons, drawing and painting species as requested for private collections and portfolios, with subjects chosen to reflect their patron’s specific ornithological interests. By the turn of the 20th century there were a small number of illustrated bird guides available commercially, such as H.E. Dresser’s A History of the Birds of Europe, published in nine parts between 1871 and 1896. However, these were extremely expensive to purchase due to high production times and costs.

One of the first widely available bird books, The Observer’s Book of British Birds, was published in 1937. Illustrated by Archibald Thorburn, who was eager to embrace the new age of print, the book included plates that showed species in a natural setting and was incredibly popular with a post-war audience. This was closely followed by The Handbook of British Birds by H.F. & G. Witherby (1938-1941) which consisted of five volumes illustrated in colour. These were later combined into a single volume: The Popular Handbook of Birds (1962). At this time, most illustrations were based on museum specimens, as fieldwork was limited by poor optics and the cost of travel, and very few photographs of live specimens were available. Because of this, images, although technically accurate, often missed details of ‘jizz’ and other useful field characteristics as well as seasonal differences in plumage.

Tunnicliffe’s ‘What To Look For In…’ series was popular with both adults and children during the post-war years.

The years and decades following the second world war saw a growing interest in birds in Britain, helped considerably by the RSPB which encouraged the creation of bird art and viewed it as a useful tool for inspiring public interest. At this time, Charles Tunnicliffe’s two albums: Bird Portraits and Wild Birds of Britain, alongside his four What To Look For In Spring/Summer/Autumn/Winter books were incredibly popular with both children and adults. Unusually for the time, Tunnicliffe only worked from real-life specimens which gave his illustrations a rare lifelike vibrancy. (Tunnicliffe is also well known for his illustrations of country life and the original wood engravings included in Tarka the Otter).

The late 1940s and 50s saw the publication of the first ‘modern’ field guides, in which much more attention was paid to identifying characteristsics, behavioural details and notes on confusion species. Of these, the Collins Pocket Guide to British Birds, illustrated by Richard Richardson and the Collins Field Guide, illustrated by American artist Roger Tory Peterson, were by far the most popular. While the Pocket Guide grouped birds by size and similarity, with no regard for taxonomic relatedness, Peterson’s book arranged birds taxonomically, a difference that split readers in their preference for each style.

Volume VIII of the ambition Birds of the Western Palearctic

The 1960s saw a huge ecological awakening in Britain, and an increased interest in the natural world. Popular bird art at this time also experienced a boom with the arrival on the scene of talented artists such as Basil Ede and Robert Gilmore, the latter of who was instrumental in forming the Society of Wildlife Artists (SWLA) in 1964. The decades following were a wonderful period for illustrated bird guides and a number of key publishers now found that it was financially viable to produce these in much higher numbers and successfully market them to the general public. Notable publications from the 1970s include the Hamlyn Guide to the Birds of Britain and Europe, The Collins Pocket Guide to Birds of Britain and Europe and the extremely ambitious Handbook of the Birds of Europe, the Middle East and North Africa, The Birds of the Western Palearctic.

The 1980s were notable for the arrival of the first modern family monographs, beginning with Seabirds in 1983, beautifully illustrated by Peter Harrison. Unlike general field guides, these focused exclusively on a single family of birds, and were incredibly popular. Seabirds was closely followed by Shorebirds, illustrated by Peter Hayman, and Wildfowl, illustrated by Hilary Burn. However, the most ambitious and well-known example of this format is the Handbook of the Birds of the World which stands at 16 volumes, published by Lynx over a period of 20 years.

Still, expectations continued to rise and the quest for the perfect field guide continued, until the Collins Bird Guide finally appeared in 1999. Renowned globally for the quality of the artwork – which is considered to be exceptional, both aesthetically and as an identification aid – this book has remained the stalwart companion for huge numbers of birders over the past two decades. The third edition, due to be published this year, features expanded text and additional colour illustrations.

More recently, a number of ambitious, large-format illustrated bird guides have been published. All the Birds of the World, published by Lynx in 2020, features more than 20,800 illustrations, covering 11,524 species. Collins Birds of the World, published a year later in 2021, is the complete collection of the Collins Field Guides’ incredibly detailed, accurate and beautiful bird paintings, brought together in one comprehensive volume. The all-encompassing guide featured 10,711 species, including 301 full-colour plates.

Seabirds is a wonderful continuation of the rich history of illustrated bird guides and is a shining example of a book which is both invaluable as an identification guide, and treasured as a work of art.

SM4/SM4BAT SD Card Compatibility Fix

This is a Technical Support Bulletin from Wildlife Acoustics regarding problems that can occur when using the SM4 family of recorders with certain SD cards.

Overview

A number of customers have recently reported deployment problems when using SanDisk Extreme and SanDisk Extreme Pro SDXC flash cards with their Song Meter SM4 family recorders. The issue can affect all Song Meter SM4 family products including the SM4, SM4TS, SM4BAT-FS, SM4M, and SM4MU (but excluding SM4BAT-ZC).

The failure generally manifests with schedules that make continuous back-to-back one-hour recordings and can result in recordings being lost. Corrupted .WAV recordings with a 256KB length and/or many .sm4dump files on the card are both indications. The issue only rarely affects schedules with short duty cycle recordings such as 10 minutes on the hour, or on triggered recordings on the SM4BAT-FS.

Note: Many of the above symptoms are normal at the end of a deployment as batteries fail. What is unique to this issue is it can occur while the batteries are fresh.

Solution

Wildlife Acoustics have released firmware version 2.3.3 that corrects this problem and may improve interoperability with other flash cards as well. We strongly advise customers to update to this latest version as soon as possible whether you are seeing issues or not. The firmware is available on the Wildlife Acoustics website after you log in to your account here: https://www.wildlifeacoustics.com/account/downloads/sm4.

Firmware version 2.3.3 also fixes an unrelated issue, introduced with firmware 2.3.1, which could result in corrupted cards that are formatted in exFAT and have the “dirty bit” set (this indicates an issue with unmounting the card previously).

Note: If you experience card corruption, Wildlife Acoustics have tools that can possibly recover recordings off the card. Contact their support team using the details below for more information.

The New Environmental Land Management scheme

The UK’s departure from the EU offers a number of opportunities for the environment, and in particular for the future of farming in the UK. And so, agricultural policy is undergoing a reform and a new payment scheme, Environmental Land Management (ELM), has been introduced in England. In the latest issue of Conservation Land Management (CLM) Alice Groom, RSPB’s senior policy officer, provides an up to date overview of what we know about ELM so far and the proposed timeline of the seven-year agricultural transition period, and, importantly, highlights the pitfalls and challenges that need to be addressed in order for ELM to be a success. Here you can read a summary of the article.

What is ELM?

Agricultural policy in the UK has previously meant that farmers and landowners receive payments based on the size of farmed land. While agri-environmental schemes have existed, these alone have not been enough to meet their environmental objectives. And so, following the UK’s departure from the EU, the government has introduced the Environmental Land Management scheme (ELM) in England.

This new payment scheme instead pays farmers for delivering public goods – these are ecosystem services that will benefit us all, such as natural flood management and habitat restoration. Defra has said that ELM is a means to meet six of the government’s 25 Year Environment Plan goals, including clean air and water, climate change mitigation, and protection from environmental hazards.

Three-component design

ELM will have three components, and although this design has received support, the finer details are currently lacking. The first, Sustainable Farming Incentive, is envisaged to be the most popular and will provide payments based on environmentally sustainable farming and land management, such as tree and woodland management, integrated pest management and promoting wildlife and biodiversity.

The Local Nature Recovery component is more focused on local-scale nature recovery with the aim to encourage farmers to create and enhance semi-natural habitats, and to use farming methods that keep chemical inputs low. Activities that are likely to receive funding under this component include natural flood management, habitat restoration and species management.

The third component, Landscape Recovery, could provide a means to achieve landscape-scale recovery using wilder approaches to farming. If successful, large expanses of habitat, such as woodland and wetlands, could be restored and large-scale activities such as peatland restoration will help contribute to net-zero emissions targets. Collaboration between landowners is key, and it is still unclear if this component can be achieved across smaller land holdings, or if this is limited to large estates.

Agricultural transition

‘The Agricultural Transition’ is a seven-year transition period in which the previous area-based subsidies will be phased out, and the first ELM National Pilot will begin. The transition begins this year, and the current intention is that ELM will be rolled out in 2024.

Although ELM has great potential to support farmers in a shift towards nature-friendly farming and land management, there is still much that remains a mystery. For instance, Defra is yet to provide information on future regulatory standards, details on how payments will operate, the application process, or what the overall annual budget for ELM will be.

The full version of this article can be found in the Spring 2021 issue, and here Alice Groom takes a closer look at each component to discuss its potential in delivering their environmental goals. Other articles featured in this issue include:

Introducing… Beaver Trust

Author Interview with Mike Alexander: Skomer Island

Renowned for its incredible and diverse wildlife, it is no wonder that Skomer Island receives thousands of visitors year upon year. Famous for its thriving populations of seabirds, grey seals and its vast swathes of spring flowers, Skomer is a fantastic example of how carefully managed eco-tourism works alongside conservation.

Mike Alexander was Warden of Skomer for ten years, and has had links to the island for over six decades. He is now Chair of the Wildlife Trust of South and West Wales and the Pembrokeshire Islands Conservation Advisory Committee. Illustrated with his own stunning photographs of the flora and fauna, this book is a comprehensive history of the island and its inhabitants.

Could you tell us a bit about your background and where the motivation for your book came from?

I first visited as a schoolboy in 1962, just a couple of years into Skomer’s incarnation as a nature reserve, and it was a day that changed my life forever. The most overwhelming idea that stayed with me from that day was that eventually, whatever it took, I would become warden of Skomer. I finally fulfilled that long-held childhood dream in the spring of 1976. Following 10 wonderful years on Skomer I moved to North Wales where initially I was responsible for the management of 5 spectacular National Nature Reserves and in 1991, I became responsible for supervising the management of the entire series of NNRs in Wales, a position I held for over twenty years. In 2018 I became the chair of the Pembrokeshire islands conservation advisory committee and so my commitment to Skomer continues.

I had long dreamed of writing a book about Skomer, but in truth had little idea of how I might achieve that goal. Skomer is a cultural landscape shaped over thousands of years by people striving to make a living. I wanted to show how the island has evolved in response to changing human values, attitudes and interventions. I also wanted an opportunity to demonstrate what nature conservation means in practice. Reserves like Skomer are the most powerful advocate for nature that we could possibly have. The island gives visitors an almost magical insight into somewhere that transcends our ordinary world, where one close encounter with a puffin may speak more eloquently for conservation than a thousand words ever could.

Previous to the island becoming an NNR in 1959, you mention Skomer’s agricultural history. Could you tell us here a little about the island’s past?

Skomer’s time as a nature reserve spans barely a moment in its history. People have occupied Skomer for millennia, and archaeologist John Evans has described Skomer as possibly unique in the completeness of its archaeological remains. Present day visitors to the island can clearly pick out faint patterns of the distant past: field systems, lynchets, hut circles and more. Until recently, archaeologists and historians believed that apart from rabbit trapping and livestock grazing, the island had been abandoned after the Iron Age. However, new excavations in 2017 revealed the presence of medieval land clearance and ploughing.

During my ten years living on Skomer I became increasingly interested in the people who had lived there before me and most of all, the 19th century inhabitants who had farmed and made their living on the island. The people of the 19th century left the heaviest footprints as theirs was a time when people imposed their will on the island, shaping the land to meet their needs. This was a period of intense intervention and although it began to fade towards the end of the century, it was a time when people had the most impact on the island, its scenery and vegetation. How long will it be before the Victorian farmers’ footprints fade away? We, the later islanders, have become noninterventionists, and observers of nature’s progress. Ours should be the lightest of all footprints, and so perhaps the impact of the 19th century will, for now, be the most enduring of all human influences.

Recent news of Skomer’s thriving populations of seabirds like the puffin and Manx shearwater offer much hope. What major changes do you think are necessary to ensure species recovery and habitat restoration in Britain?

My generation has grown up with an almost subliminal pessimism about the fate of our wildlife to the point where decline seems inevitable and we can only hope to slow the rate of it. To have seen Skomer thrive throughout its time as a nature reserve is contrary to nearly everything I have grown up to believe, and yet it is important to remember that Skomer once had the potential for so much more. We know from photographs taken around the turn of the last century, that there was a minimum island population of around 100,000 Guillemots: four times the present number. The photographs also show the grassy slopes above the cliffs thick with Puffins, where now they only form a thin fringe. Perhaps these things will not be possible again, but it is a vital reminder never to set our sights too low and to hold on to that vision of what the future could be.

Species and habitat recovery will only happen when our policies and legislation are translated into action. Good intentions alone will achieve nothing. It is quite ironic that despite the enormous growth in public concern and protest about the fate of our natural environment, governments are failing to provide the essential resources.

The NNRs, along with all other protected areas, will be a central and essential component of any species and habitat recovery or restoration programme. They are the stepping stones, the vital reservoirs and the crucial resources that will enable landscape scale recovery in Britain.

With restricted movement during the Covid-19 pandemic that many are referring to as the ‘anthropause’, people across the globe have noticed changes to their local wildlife. How has the lack of eco-tourism affected the wildlife on Skomer during this time?

Skomer is an extremely fragile island with hundreds of thousands of seabirds. Puffins and Manx Shearwaters nest in shallow burrows, while the cliffs provide homes for thousands of Guillemots, Razorbills and Kittiwakes. As a consequence, all visitors to the island understand that they must keep to the system of marked footpaths at all times. This has made it possible for us to claim with confidence that visitors to Skomer have no impact on the wildlife that they come to enjoy. So apart from overgrown paths, there has been no significant discernible impact.

There are plenty of signs from elsewhere that wildlife has responded positively to the lack of human disturbance. It may well be that some species will gain a short-term advantage, but I am not convinced that the impact of Covid-19 on wildlife will be anything more than a very minor, and almost irrelevant, hiccup, unless of course we can learn from the experience. We must learn to change our behaviour and realise that we will not survive on this planet if we regard unfettered consumerism as our main purpose in life.

Do you have any other projects on the horizon you’d like to tell us about?

I will take a break from writing and concentrate on photography. I was recently elected Chair of the Wildlife Trust of South and West Wales and I am looking forward to devoting much of my time to working for the Trust.

Author Interview with Mary Colwell: Beak, Tooth and Claw

With the recent return of the white-tailed sea eagle to Britain and the mooted return of the Lynx, living with predators is becoming a much more frequent topic of conversation. In Beak, Tooth and Claw, Mary Colwell explores our past and present relationship with predators in the UK, and considers what it might look like in the future.

Author of Curlew Moon, Mary Colwell is an award-winning conservationist, writer and producer, and has written for the Guardian, BBC Wildlife Magazine, Country Life and many other publications. She has very kindly agreed to answer some of our questions about her latest book.

Could you start by telling us a little bit about your background and how you got into conservation?

I became interested in conservation during my career at the BBC Natural History Unit, when it became clear just how much was going wrong. A lot of my work as a producer was celebrating nature, but it was apparent that the beautiful pictures were covering over a fractured, damaged world. Wild creatures are struggling to make their lives work in our increasingly human-dominated landscapes, and this rich, vibrant planet is thinning out. Over the years the press releases I read, particularly from Ireland, highlighting the decline of curlews were eye-watering. It ate away at me, this relentless destruction, and I decided I had to get more involved. Not so much in the fieldwork and practicality, but in doing what I had been trained to do – tell the stories of the earth and help make the problems accessible and understandable to people like me, non-specialists who care.

Following on from Curlew Moon, what was it that made you decide to write a book about predators?

I was naïve when I first got involved in curlew conservation, I had no idea how enmeshed they are in the biggest conservation issues we face in the 21^st century, namely predator control, habitat loss to farming, afforestation and development, climate change, increasing pressure from leisure activities and so on. The predator issue seemed particularly potent in the uplands on grouse moors, but it is a source of contention everywhere. How people view predators is rarely based on science, it is shrouded in cultural attitudes and traditions. I found this interesting, and it also pointed to a way forwards. If conservationists can work with communities within their world view, on the ground projects are far more likely to succeed than trying to impose solutions on people. I don’t have definitive answers, but I explore this in the book.

Carefully managed reintroduction of some of Britain’s predators has already proved hugely beneficial to biodiversity, and may also pose future economic advantages. What lost species would you like to see returned to Britain next?

In Chapter 8 I look at reintroductions, and I think what is happening is a very good way to go. Start with wildcat then scale up. The quiet, efficient regulator of woodlands, the lynx next. If we ever find it possible to introduce wolves, it would be incredible, we would live in a very different country, both the physical landscape of Britain, but also the landscapes of our minds would change. We will be wilder in every sense. It won’t be easy, in fact it is probably not possible given the direction of travel and the density of the human population, but it is tantalising to think about. I’m aware, though, that it is easy to glow with excitement about wolves in the wilds of Britain, but living with them on the doorstep will be a challenge for rural communities.

Opposing views on predators and reintroduction projects seem irreconcilable – do you think there is any way both sides of the argument can find common ground?

We will only welcome big predators back into our lives if we feel secure in their presence. As long as they are perceived as a threat to us, both physically and metaphorically, there will be opposition. The solution is to find ways that will assuage fear and highlight the positive aspects of their presence. And there are many positives as well as issues to face honestly and with understanding. There have been centuries of mis-information and vilifying which can’t be unravelled quickly. This is the long game, the gentle, constant discussion of facts and the erosion of fiction. Taking away fear is not easy, but I hope we get to a place where, although it might feel like a scary and difficult step to take, we will all put our hearts behind a new, wilder world.

What’s your vision for the future of conservation and rewilding in the UK? Are you hopeful or pessimistic?

This is the hardest question of all. The future of conservation and the future of rewilding seem, in some ways, like different topics. The future of conservation relies on the pincer movement of sound environmental policies that make it easier for landowners/developers etc to do the right thing, and citizens wanting to have more nature and helping make it happen. We have to incentivise land use that makes wildlife worth preserving and we have to educate people about nature and our role in the natural world – something that has been largely side-lined over the 20^th century. We need to create a more nature-literate society, one where people understand the issues and can make informed decisions. Who knows if the government’s 25-year plan and green vision will play out as we all hope, but it is there and it is welcome and we all have a role to play in enabling it.

Rewilding is part of that vision, but it is a catch-all term that has a variety of meanings. I take it as increasing biodiversity across Britain, rather than simply the idea that we should let nature go wild without any human interference. The way we live in the UK has made pure, unadulterated nature a dream, not a reality. There is nowhere that is wild but everywhere could be wilder. Rewilding for me is doing what needs to be done, area by area, bit by bit, to increase the net amount of nature across the UK.

Am I optimistic? On the whole, yes. My experience in starting Curlew Action gives me hope. We are a tiny charity that is only 18 months old, yet the support we have been given is amazing. ‘Ordinary’ people (no one is ordinary!) have supported us in a simple, clear way – they want to show how much they care for nature, and that has been so heartening. Even if many of us are not skilled in the field, we can all play a part in raising awareness and fund raising for conservation efforts to help wildlife.

Always, my advice is – pick something to love and love it. Love never comes alone, it is accompanied by barrow-loads of responsibility and care – so simply saying “I love nature” is not enough. If you love something you will move heaven and earth for it. I think many people will do that if they feel they have permission, despite not being an “expert”, so yes, I am optimistic.

Do you have any projects in the pipeline you’d like to tell us about?

I am so keen to push through the long awaited plan for a GCSE in Natural History. We are just waiting for a final yes from the Department of Education – once we have that we are up and running. So I shall continue to work away at that. I am starting my next book for Bloomsbury on walking the Camino last winter in between lockdowns – a 500-mile pilgrimage across northern Spain. The natural world was a constant companion, and it got me wondering about our relationship with nature over the 1000 years people have walked this track. I am also now Chair of the newly formed, Defra supported, Curlew Recovery Partnership, a roundtable of 9 organisations and an extensive network charged with turning it around for curlews over the next 10 years. With Curlew Action work and other projects constantly ticking away, life is full and fascinating.

Devon Badger Group: Interview with Chair, Jenny Pike

Formed in 2010, the core aim of the Devon Badger Group is to protect badgers and their habitats. Funded by membership, donations and fundraising events around Devon, they run a free 24/7 helpline for sick or injured badgers and other badger-related issues.

We recently had the opportunity to chat with Jenny Pike, Chair of the Devon Badger Group, about the group’s important work, their successes and challenges, and how Covid-19 has affected their lives over the past year.

Firstly, can you give us a brief introduction to the Devon Badger Group and your role within the group?

My name is Jenny Pike and I am Chair of the Devon Badger Group (DBG). In a nutshell, the purpose of the DBG is to protect badgers and their habitat, record their activity, educate and further the public’s understanding of badgers, and to encourage tolerance, appreciation and respect for all wildlife. We also work with the police and RSPCA, and respond to any activities that could be detrimental to the welfare of badgers.

What do you consider to be the main threats to badgers in the UK?

Sadly there are many threats to badgers and, despite gaining legal protection in 1992, badger persecution is on the increase. In England, one of the biggest threats badgers face is the government licenced badger cull. Since the cull began in England in 2013, a total of 140,991 badgers have been killed, 30,345 of which have been in Devon.

Other serious threats are housing developments where, even if setts are protected with appropriate mitigation measures, a significant amount of foraging ground can be lost. New roads can also impact badgers if appropriate badger tunnels are not installed or are installed in the wrong place. Hunts sometimes block badger setts to prevent foxes escaping down them and, as already mentioned, illegal badger persecution is on the rise along with other forms of organised wildlife crime such as dog fighting.

I am sure everyone will have seen many badgers dead on the side of the road. No one knows exactly how many badgers are killed by vehicles each year – one estimate has it at 50,000.

What are your main goals as a group?

Our main aims are to protect badgers, their setts, and their habitats. But we feel that if we can increase the public’s understanding of badgers and dispel some of the myths, people will feel more encouraged to protect them. Sadly, most people we talk to have never seen a live badger. This is why, whenever we are contacted by members of the public who think they have badgers visiting their gardens, we offer to put up a trail camera so they can actually watch visiting badgers go about their business, which is usually looking for earthworms and other invertebrates. This often has a very positive effect and has changed people’s view of badgers.

What would you consider to be your greatest success as a group?

In 2019, through some very generous grants and donations, the DBG was able to fund two members to train to become licenced lay vaccinators. I was lucky enough to be one of them. Since then, we have worked in collaboration with the Somerset Badger Group to vaccinate badgers in Devon and Somerset, which has allowed us to gain valuable experience. We hope this will continue and expand in the future.

Covid-19 has caused difficulties and presented issues for all of us. How has the pandemic affected the work that the DBG does, and have there been any unforeseen positive effects?

On the positive side, it is possible that less cars on the road in the first lockdown resulted in fewer badgers being killed or injured. Spring is when cubs are still dependent on their mums and when most road casualties occur, and so this would have had a significant effect on badger cub survival rates if mum survived to successfully wean them.

On the negative side, although we were given permission by Devon and Cornwall Police to continue to rescue injured badgers on animal welfare grounds, we were not able to carry out sett surveys, monitor setts which had been targeted previously, or visit homeowners who had contacted us for advice on badger issues. We were also unable to carry out our regular fundraising activities which, in normal circumstances, not only provides much needed funds, but also gives us an important opportunity to engage with the public and answer their questions. This is something I personally have missed a great deal as there is no substitute for face-to-face communication.

Having said that, we have been able to continue our most important work by keeping in regular contact with our committee and members through electronic communication, Zoom and Teams meetings. This has had an unexpected benefit of not only reducing our carbon footprint, but also allowing us to engage with our members across the whole of the county (internet permitting!).

You mention that you sometimes use trail cameras in some of your work – could you tell us a bit more about this?

We use trail cameras extensively in the DBG and they have been invaluable in proving setts are active in cases of sett disturbance and sett blocking. They have also been used to great effect when showing school children the wonders of a shy nocturnal animal they would never usually see. I have been using a number of cameras recently on a beaver enclosure to ensure the badgers and other wildlife are able to move freely in and out (except the beavers of course!). I also have my own trail camera and I still maintain that it was the best Christmas present ever. I use it all the time for monitoring the wildlife in my own garden in Plymouth.

In May of last year, the government announced that they hope to shift away from culling and towards badger vaccination to help in the fight to eradicate bovine tuberculosis (bTB) in England. What does this mean for the group and will the DBG be involved with badger vaccination programmes?

The Devon Badger Group is opposed to the badger culls but, of course, recognises the distress and hardship bTB causes for farmers, their families and their animals. We sincerely hope that the government honours its commitment to progressing a vaccine which is much more likely to provide real benefits to farmers and their cattle than the current bTB strategy.

Controlling the spread of bTB is a complex issue that will need a raft of measures to tackle, but they must all be backed up by sound scientific evidence. The role badgers play in bTB transmission is still not fully understood: what limited studies have been carried out to determine the prevalence of bTB in badgers have concluded that approximately 4.5% of badgers tested are infected with bTB. It is now accepted that the vast majority of bTB transmission to cattle is from other cattle, but this was previously unclear due to the poor accuracy of the routinely used skin test. This skin test has been found to be around 50-80% accurate, resulting in up to 1 in 5 infected cattle remaining undetected in the herd to pass on the infection.

With this in mind, and the fact that bTB can live in soil and slurry for many months, there is enough doubt on the role badgers play in disease transmission to compel the government to re-evaluate their bTB strategy for the benefit of farmers and the whole farming industry.

We welcome the government’s commitment to replace badger culling with the more humane badger vaccination and we hope to be involved in any future badger vaccination initiatives. We would be very happy to work with and support Defra and other organisations in delivering on this new initiative until a more effective cattle vaccine can be deployed.

It is obvious that you are very passionate about badgers and love them dearly. What is your favourite fact about badgers?

As large as they are, their main food source is earthworms and they have to delicately pull them out of the ground without snapping them!

How can people help protect badgers and get involved in their local area?

Please keep an eye on your local area, especially if you have any setts near you. If you would like help on identifying signs of badgers, we would be more than happy to help (Covid-19 permitting).

Report any suspicious activity around badger setts to the police and do also let us know. Please also report dead badgers to us – in spring this is important if it is a lactating female with dependent cubs below ground.

Please consider joining the Devon Badger Group. We are a small but active group but have one of the largest and most rural counties in England to cover.

We can be contacted at devonbadgergroup@gmail.com and on our 24/7 helpline number 07710 971988 or I can be contacted direct on 07791 490572.

Campaign to ban the use of peat-based composts in the UK

A UK campaign, headed by Professor Dave Goulson, has called upon the government to ban the use of peat in garden compost by the end of 2021.

In 2011, voluntary targets were set by the government with the aim of ending the domestic sale of peat-based composts by the end of 2020. But, in a recent letter to the environment secretary, George Eustice, Goulson explains that these targets have been an ‘abject failure’. The letter, which has been signed by a long list of notable conservationists, scientists and gardeners – including Alan Tichmarsh, Isabella Tree and Kate Bradbury – goes on to suggest that banning peat-based composts before the COP26 climate conference is a vital step in demonstrating the UK government’s dedication to addressing the climate crisis.

Why is peat important?

Globally, peatlands store half a trillion tonnes of carbon; this is twice as much as is stored in the world’s forests. In the UK alone, peatlands hold more than three billion tonnes of carbon although, worryingly, only 20% exist in a natural or near natural state. Peatlands also provide important habitat for many species of plants and animals and play a critical role in reducing flooding.

As well as the extraction of peat for use in the garden trade, these areas are under threat from overgrazing, draining (so that land can be made suitable for farming), and burning of the surface heather, particularly on grouse shooting estates.

Peatlands grow from the slow accumulation of dead plant material in wet terrestrial habitats and take an incredibly long time to form. When the peat is extracted or damaged, the stored carbon that has built up over centuries is released into the atmosphere. Because of this, the UK’s peatlands are now acting as a net carbon source, rather than an environmentally critical store.

How can I help?

As a gardener and consumer, one of the most important things you can do is to commit to only buying composts that are peat-free. Or, better still, if you have the space, try making your own from kitchen and garden waste. As stated in Goulson’s letter ‘Unearthing this precious store of carbon to use in the garden is needless, given that there are high-quality peat-free alternatives available’. Following a survey conducted by the Wildlife Trusts, only two garden retailers declared an end-date for peat sales: Travis Perkins in 2021 and Wickes by 2025. Other retailers, including B&Q, Asda and Lidl said they were committed to phasing out peat products but gave no date.
For anyone purchasing plants from nurseries, the Dogwood Days blog provides a comprehensive list of plant nurseries that are peat-free on site and/or committed to sourcing peat-free plants.
Sign the petition to ‘Ban the use of peat in horticulture and all growing media by 2023‘. The deadline for this petition is 6th June 2021, and 10,000 signatures are required to ensure a government response.

Nurture for Nature: Interview with Dr. Amir Khan

Dr. Amir Khan is a GP, well-known for his regular appearances on Lorraine and Good Morning Britain. As a lifelong lover of wildlife, he is also ambassador for the Wildlife Trusts and Butterfly Conservation. He is passionate about connection with the natural world as a mutually beneficial practice which can not only improve our mental and physical health, but is also necessary to ensure the conservation and biodiversity of local areas.

From April this year, Dr. Khan is fronting Butterfly Conservation’s Nurture for Nature campaign which aims to get people involved with the wildlife in their gardens and local wild spaces. We recently chatted with him about the campaign as well as his love of the natural world.

Your incredibly popular Instagram and Twitter accounts are full of beautiful images and descriptions of your local wildlife encounters. Have wildlife and conservation always been passions of yours?

I have been a lover of wildlife from an early age, my dad and I used to watch nature documentaries together. He wasn’t well enough to get out of the house so I would tell him about what I had seen in the woods or local park. As I got older, I learned about wildlife gardening and the importance of nature on our health. I am passionate about everyone, from all walks of life, having access to nature and that means conserving it. It has such important wellbeing effects that everyone should get to experience. I experienced the benefits of nature on my mental health during the pandemic, when I would come home from the surgery after visiting my patients in nursing homes; nature helped me during these difficult times.

As an ambassador for Butterfly Conservation you are also going to be fronting their new Nurture for Nature campaign. Can you tell us a bit more about this and what it hopes to achieve?

Butterflies and insects are vital pollinators and we need them in our lives to keep us alive! By understanding that by helping nature we are actually helping ourselves, I am hoping people will see the wider benefit of doing simple things that can encourage some of these wonderful creatures to visit them. We have to remember that, at this time of year, many insects are emerging from a long winter and need areas where they can feed to get them going for the spring and summer months. They will then get the mental and physical benefits that being close to nature provides and our insects get more areas to feed, drink and rest.

Hopefully lots more people will be inspired to get into their gardens this year as a result of the campaign. Do you have plans for your own garden this year?

I am really excited about my garden this year. After what feels like a very long winter, I want my garden to feel like a haven for both myself and the wildlife that visit or live there. I am making sure every corner has something in it to entice wildlife. There is nothing better than a summer’s day in the garden, simply watching the insects going about their business whilst you potter about. And knowing they are feeding off the plants and flowers you planted is a lovely feeling.

We’ve also heard that you’re hoping to get into moth trapping! What is it about moths that interests you?

I absolutely love moths! I think they are the most underrated insects in our gardens. They are vital pollinators but have a bit of a bad reputation, probably down to the fact that many of them are nocturnal so we are just not as familiar with them. I want to show people that moths are just as amazing as butterflies and just as beautiful. By doing some moth trapping this summer I am hoping to catch and showcase some of the gorgeous moths that live right under our noses!

It’s fascinating to read about the link between lifestyle choices and their impacts on mental and physical health. How do you feel that a connection with wildlife and an appreciation for nature fit into this picture?

There is so much proven science behind the wellbeing effects of nature. When we are amongst natural spaces, listening to bird song or spending time immersed in nature, our bodies produce chemicals that make us feel content and happy – we produce less stress hormones which can help reduce blood pressure and heart rate, having an overall calming feeling on our minds and bodies. We need to embrace and encourage this as part of our every day lifestyles. This is why we need to conserve green spaces so that everyone can benefit from them.
