‘Wilding for Conservation’ series – one year in

Rewilding has remained very much in vogue over the past 12 months: a wealth of new initiatives and enterprises have emerged, ‘celebrity rewilders’ have made headlines and, most significantly, Defra has announced recently that one part of the new, restructured farm-subsidy system in England will incentivise a switch from agriculture to nature restoration on large landholdings. With momentum only set to build, discussion of the direction of travel, and opportunities and challenges for rewilding remains as important as ever – the ‘Wilding for Conservation’ series, launched in British Wildlife at the start of 2021, aims to provide a forum for that discussion. Here, we revisit the varied topics covered in the series’ first year and look ahead to articles coming up in 2022 and beyond.

Wilding for Conservation, edited by Rob Fuller, began in the February 2021 issue of British Wildlife with an editorial explaining the aims of the series, including to ‘explore the many facets of rewilding as they relate to conservation in Britain’ and ‘bring ideas contained within the expanding scientific and cultural literature to a wider audience, while providing examples of what is happening on the ground in the UK and elsewhere’.

That same issue featured the first two articles in the series. To start, Steve Carver and Ian Convery set out the history and principles of rewilding, and argued that this approach in its pure form could offer a more ambitious future for conservation in Britain. Accompanying this was a piece by Rob Fuller and James Gilroy, who examined the limitations of, and similarities between, rewilding and ‘traditional’ conservation management, and discussed how the two could be used in tandem to produce the greatest possible benefit for wildlife.

In the May 2021 issue, Jonathan Spencer explored the economics of rewilding, offering a brief history of how industry first maintained, and then later destroyed, high-nature-value habitats, and explaining how the emergence of natural capital approaches and changes to farm subsidies could present new financial opportunities for rewilding enterprises.

In June, Keith Kirby, described European strict forest reserves – protected woodlands left to develop with minimal intervention – and outlined how these might provide lessons for rewilding in British forests.

In the November issue, Hugh Webster reviewed the ability of large carnivores, including wolf and lynx, to regulate populations of other species, and cautioned against building the case for reintroduction of apex predators on their potential ecological benefits, which may fail to materialise.

Most recently, in December 2021, the charity Rewilding Britain introduced a selection of projects currently trialling wilder approaches to conservation, and explained how rewilding can be applied, and yield benefits, in a great variety of contexts.

Wilding for Conservation will continue through 2022 and beyond with articles on a range of topics, including a landscape-history perspective on the limits of rewilding, the reality of passive rewilding in established woodland, the roles of rewilding in carbon storage and mitigating the impacts of climate change on wildlife, case studies on the New Forest and Southern Uplands of Scotland, and much more. And alongside the series, British Wildlife will continue to bring readers the best of natural history and species conservation, and the most important developments in environmental policy.

Edward O. Wilson and Thomas Lovejoy Obituary

Edward O. Wilson 1929–2021 and Thomas Lovejoy 1941–2021

We have recently received the sad news of the passing of Edward O. Wilson, a biologist, naturalist and Pulitzer Prize-winning author, who died aged 92 and Thomas Lovejoy, a leading extinction researcher and conservation biologist who popularised the term ‘biological diversity’, who died at age 80. These two pioneering conservationists were instrumental in establishing the field of conservation biology and continued to contribute to conservation and research throughout their long careers.

Edward O. Wilson began his interest in natural history from an early age, undertaking his first expeditions at age 9 around the Rock Creek Park in Washington, DC. He earned his BS and MS degrees in biology at the University of Alabama before transferring to Harvard University to complete his PhD.

Wilson was referred to by some as the ‘father of biodiversity’ and ‘a modern Charles Darwin’, praised for his influence as a theorist and observer. He began his career as an ant taxonomist between 1956 and 1996, working to understand their microevolutions and developing the theory of a ‘taxon cycle’. While appointed to the Harvard Society of Fellows, he spent many years travelling, embarking on several overseas expeditions to research and collect ant species in Cuba, Mexico, Australia, Fiji and Sri Lanka, amongst other places. Wilson has been credited with the discovery and description of more than 400 species of ants. Later in life, he led a number of scientific expeditions to Mozambique, the southwest Pacific and the archipelagos of Vanuatu.

Wilson was also an accomplished author, publishing many titles including On Human Nature (1979), which won him his first Pulitzer Prize; The Ants (1990), for which he won his second Pulitzer Prize; his autobiography Naturalist (1994); The Diversity of Life (2012); Letters to a Young Scientist (2014); and his most recent book, Tales from the Ant World (2021). Wilson also played a key role in the launch of the Encyclopedia of Life (EOL) initiative, which aimed to create a global database on all scientifically recognised species.

He was also known for his campaigning, arguing that humans have a moral duty to value species for not only their own sake, but also for future human generations. His work in extinction research informed much of his activism, leading to his advocating for forest protection and the setting aside of 50% of the earth’s surface for wildlife to thrive in, known as the Half-Earth concept. During his long career, Wilson was awarded a number of scientific and conservation honours, including the National Medal of Science (1977), the ECI Prize (1987), the International Prize for Biology (1993), Carl Sagan Award for Public Understanding of Science (1994), the Nierenberg Prize (2001) and the Kew International Medal (2014), as well as being recognised as one of Time Magazine‘s 25 Most Influential People in America in 1995.

Edward O. Wilson: 10th June 1929–26th December 2021

Thomas Lovejoy introduced the term ‘biological diversity’ to the scientific community in the 1980s, as well as helping to establish the concept and study of conservation biology, by convening ‘The First International Conference on Research in Conservation Biology’ with a group of other leading conservationists in 1978.

Referred to by some as the ‘godfather of biodiversity’, Lovejoy’s interest in nature and biology began when he attended Millbrook School and worked at The Trevor Zoo in the 1950s. From there, he worked for many years in the Amazon of Brazil, later founding the Biological Dynamics of Forest Fragments Project (BDFFP) in Brazil in 1979 and later co-founding the Amazon Biodiversity Center in 2018. He worked to understand the impacts of forest fragmentation, leading the Minimum Critical Size of Ecosystems project in the Amazon and calling for the protection of tropical forests.

Lovejoy served on a number of science and environmental councils under presidents Reagan, Bush and Clinton and as Science Envoy for the Obama and Biden administrations. Through his work in the field of extinction research, he discovered that human-caused habitat destruction, pollution and climate change were threatening species around the world and predicted in the 1980s that 10–20% of all species would be extinct by the year 2020. This work won him the Blue Planet Prize in 2012, for being the first scientist to academically clarify how humans are causing habitat fragmentation and driving the biodiversity crisis.

Lovejoy also developed debt-for-nature swaps, where a part of a nation’s foreign debt can be forgiven in exchange for investments in environmental conservation measures, such as setting aside land as a nature preserve that would be off-limits to development. Throughout his career, Lovejoy authored many articles and books, while also providing forewords for numerous others. He helped to found the long-running TV series NATURE, a show that has educated and inspired the public about wildlife for over 40 years.

The NHBS Guide to UK Rabbit and Hare Identification

Rabbits and hares are species in the family Leporidae, which contains over 60 species. They are mammals within the order Lagomorpha, together with the pikas. They are small to moderate-sized species, characterised by long hind legs, long ears and rapid movements. They are almost exclusively herbivorous, feeding mainly on grasses and herbs, although they do also eat leaves, fruits and seeds. Leporids are coprophagous, meaning they pass food through their digestive system twice. To do this, they first expel the food as soft green faeces, termed cecotropes, which they then reingest, eventually expelling it again as dark faecal pellets. This increases their ability to break down and digest plant material, extracting further nutrients.

They inhabit a wide range of habitats, from mountains and wetlands to forests and grasslands. Leporids play an essential role in many of these ecosystems, as seed dispersers, ecosystem engineers (a species that significantly modifies their environment) and as a primary prey item for a number of predator species, such as foxes, wildcats and some mustelids, including stoats and weasels. Their young are particularly vulnerable to these predators, as well as badgers, domestic cats and several birds of prey. Because of this vulnerability, many leporids have large litters, often nesting in burrows underground to protect their young from predation.

One threat to populations, particularly in European rabbits, is myxomatosis, a disease caused by the poxvirus Myxoma virus. Its two natural hosts, the tapeti and brush rabbits of South, Central and North America, experience only mild disease. However, myxomatosis is a severe and usually fatal disease in European rabbits. When the disease originally spread to the UK in the early 1950s, the mortality rate was 99%. In the 1970s this declined to between 47 and 69% but populations were severely affected. The disease, which causes localised swelling, skin lesions, blindness and respiratory distress, has also been deliberately introduced into the wild on multiple occasions. Used to try to eradicate or control rabbit pest populations, myxomatosis was intentionally introduced in Australia, New Zealand, South America and parts of Europe, including Britain.

Other threats to leporid populations include rabbit haemorrhagic disease (RHDV1 and RHDV2), hunting, habitat loss and agricultural intensification. Rabbit populations declined by 64% in the UK between 1996 and 2018 and numbers of brown, mountain and Irish hares are also thought to have declined in some areas. As ecosystem engineers, the loss or reduction of these species can have major consequences, particularly for rabbit-dependent habitats. In their absence, the consequent changes in vegetation structure due to a lack of grazing can have further impacts on other wildlife, such as invertebrates.

Rabbit (Oryctolagus cuniculus)

Distribution: Widespread across the UK, although they are absent from Rum, Isles of Scilly and some smaller islands.
What to look for: Rabbits are the smallest leporids in the UK, with the characteristic long ears and long hind legs. They have a sandy, grey-brown colouration and a white tail. They have dark, amber coloured eyes. Other than their size, the most noticeable difference between rabbits and other leporids in the UK is the lack of a black tip on the ears.
Did you know? The rabbit, also known as a coney, is not native to the UK. The exact date of their introduction is one of ongoing research. It was previously thought that rabbits were first introduced by the Normans in the 11th or 12th century as both a food and fur resource. But the recent re-examination and radiocarbon dating of a bone found at a Roman palace show that at least one rabbit was present much earlier, in the first century AD. Researchers have stated that there is no evidence of many rabbits in the area and another analysis suggests the rabbit was kept in confinement, therefore it has been suggested that it was most likely kept as an exotic pet.

Brown hare (Lepus eueopaeus)

Distribution: Widespread across the UK, although they are less common and more restricted in Northern Ireland and absent from parts of north-west Scotland.
What to look for: This species is larger than the rabbit, with long, black-tipped ears and very long hind legs. Their colouration is redder than the rabbit and the mountain hare, and they have a black-topped tail that is white underneath. The brown hare has amber eyes and their fur can appear grizzled.
Did you know? This species is also non-native and were introduced in the Iron Age. Radiocarbon dating of bones found in Hampshire and Hertfordshire, along with historical accounts, suggest that brown hare were not eaten until hundreds of years later during the Roman period, and were instead associated with deities.

Mountain hare (Lepus timidus)

Distribution: Mainly in the highlands of Scotland, although they are also found in other areas of Scotland, on some Scottish islands and in the Peak District.
What to look for: This species has a grey-brown coat during the summer and a white coat in the winter, although the tips of their ears remain black in both forms and their tail remains white. They have brown eyes and long ears, although these are shorter than the brown hare’s.

Brown form: Andrew via Flickr
White form: John Johnston via Flickr
Irish hare (Lepus timidus hibernicus)

Distribution: Widespread across Ireland
What to look for: They are very visually similar to the mountain hare, except they do not develop a white coat during winter months and are noticeably smaller. During the summer, their coat is reddish-brown which dulls to grey-brown in winter, although their tail remains pure white.
Did you know? The Irish hare is a subspecies of the mountain hare and is the only lagomorph species native to Ireland. Fossil carbon dating suggests that these hares have been present in Ireland for at least 30,000 years.

Domestic rabbit (feral) (Oryctolagus cuniculus domesticus)

Distribution: Unknown
What to look for: Domestic rabbits can have a huge variety of appearances, with at least 305 breeds of domestic rabbits around the world, although different numbers are accepted by different organisations. They can vary in size, colouration, body shape, coat type and ear length.
Did you know? Many pet rabbits are abandoned each year, particularly in the period after Easter.

This Week in Biodiversity News – 3rd January 2022

Chester Zoo helps reintroduce ‘extinct fish’ to Mexico. The tequila fish (Zoogoneticus tequila) is a small species of goodied fish that disappeared from the wild in 2003 due to water pollution and the introduction of invasive fish species. A team of conservationists from Chester Zoo and the Michoacana University of Mexico have returned over 1500 fish to a number of springs in the Teuchitlán River in south-west Mexico, with the fish now thriving and breeding in the river. This project is hoped to have created a blueprint for future reintroductions of other endangered fish species.

Baby hellbender salamanders hatch at the St. Louis Zoo in Missouri, with hopes of restoring this species in the wild. The population of this species in Missouri has declined by over 75% since the 1980s, as they’re sensitive to environmental changes caused by climate change, pollution, disease and habitat modification. Chytridiomycosis, the deadly amphibian disease linked to massive worldwide amphibian die-offs, has also been detected in Missouri hellbenders. These captive-bred eggs will be carefully monitored and the hatchlings will be released into the wild when they are two years old.

19 bird species have been added to Nepal’s list of nationally threatened birds in the past decade. As of 2018, this list consists of 168 birds, with aquatic species making up 49 of these. The nationwide count of aquatic birds is taking place between 1st and 16th January, and will show the latest condition of the threatened bird species in Nepal. This increasing number of threatened species is thought to be due to a number of issues, including shrinking forest cover and wetlands, habitat destruction, chemical poisoning, land fragmentation, climate change and hunting.

The National Trust, RSPB, Woodland Trust and The Wildlife Trusts are calling on the Prime Minister to make New Year’s resolutions to tackle the climate and nature crises. These conservation charities are asking the UK government to make seven commitments for 2022 that focus on the protection and restoration of peatlands, protection for our marine environments and paying farmers to restore nature.

NHBS Staff Picks 2021

Welcome to our annual round-up of the books and equipment we have enjoyed reading and using this year, all chosen by members of the NHBS team. Here are our staff picks for 2021!

Song Meter Micro

Released earlier this year, the Song Meter Micro produces high-quality soundscape recordings at a significantly lower price point than standard acoustic recorders. The Micro opens the door to keen naturalists, like myself, to begin exploring the world of bioacoustics. This spring, we recorded our local dawn chorus (highly recommended!) and found it incredibly easy to set up using the free app on our own smartphone. Of particular use was the preset recording schedules, one of which uses your location and time zone to target recording around sunset and sunrise. The ease of use and beautifully clear recordings make the Micro a clear choice for my 2021 staff pick.

Islands of Abandonment: Life in the Post-Human Landscape

Officially abandoned places are often still very much inhabited by people on the fringes of society, as well as being reclaimed by nature. Islands of Abandonment is a highly enjoyable read about places, people and nature; part travelogue, part anthropology and part natural history, it reminded me strongly of The World Without Us. Cal Flyn writes engagingly, intelligently, and with compassion. I enjoyed reading this in hardback when it was first published, and the paperback is due to be released soon.
Anneli – Head of Finance and Operations

 

Recon Force Elite HP4

Being able to record the presence and often secret behaviour of the more elusive wildlife on my local patch with a trail camera is thoroughly rewarding. At the start of the year, Browning launched their latest trail camera, the impressively well-designed Recon Force Elite HP4. After seeing the stunning quality of video it captures in 1920 x 1080 FHD, it has become one of my firm favourites and I am excited to get it out into a wider range of habitats. Just ten years ago, having a trail camera that could record in this quality and also offer so many practical features and settings would have been prohibitively expensive, so I feel the Recon Force really does offer excellent value.
Ian – Wildlife Equipment Specialist

 

Beasts Before Us: The Untold Story of Mammal Origins and Evolution

Beyond a few academic textbooks and technical monographs, the deep evolutionary history of mammals has remained largely hidden in the academic literature. Beasts Before Us unleashes their story most spectacularly and engagingly. This beautifully written debut marks Panciroli as a noteworthy new popular science author.
Leon – Catalogue Editor

 

Defender Metal Seed Feeder

I have a Defender Metal Seed Feeder in my garden and absolutely love it. The ports and perches are all made of metal meaning that the local squirrel isn’t able to chew and wreck the feeder! Everything is easy to disassemble and reassemble, making cleaning the entire feeder a breeze. Paying a little bit extra for a metal bird feeder was definitely well worth it for the quality and longevity.
Antonia – Wildlife Equipment Manager

 

A Trillion Trees: How We Can Reforest Our World

A Trillion Trees is my choice for this year’s staff picks as it’s an optimistic take on the future of the world’s forests, championing the role of trees in the fight against climate change and in people’s daily lives. This book celebrates trees, exploring their importance, the history of our relationship with forests and the future role they may have in an emerging community-centred approach to the land.
Hana – Ecology Content Writer/Editor

 

Kite Falco Binoculars

Kite Optics have a great reputation for their entry- and mid-level optics. I’ve had my 8×32 Falcos for a few months now, and I’m absolutely loving them. The ED glass provides a bright, crystal-clear image even in lower light, while the smaller size keeps them portable. In most lights very little chromatic aberration is visible. I’ve had great fun seeing some of the winter migrants that are currently in residence around the UK’s coasts. A great choice for any birder looking for quality optics at a good price.
Josh – Wildlife Equipment Specialist

 

NHBS Moth Trap Starter Kit

Handmade in our workshop here in Devon, the NHBS Moth trap is my 2021 staff pick. Constructed from lightweight plastic panels covered with white nylon and weighing in at 2kg, the trap is portable, easy to assemble, and convenient to store. The sturdy 4.5m mains power lead runs a single 20W Blacklight bulb and the white fabric sides help to reflect UV light ensuring good attraction rates. I’ve always been a fan of the standard skinner shape which allows you to easily lay egg boxes along the bottom, whilst the upper panels help to retain the catch. At an attractive price point, this trap is ideal for beginners or anyone looking for a convenient trap for their garden.
Johnny – Senior Wildlife Equipment Specialist

 

Advanced Bug Hunting Kit

Although it’s a product we’ve sold for a long time, my staff pick is the Advanced Bug Hunting Kit. This year I fell back in love with bug hunting in my local area. While not being able to travel far but having the freedom to explore my surrounding countryside, bug hunting helped transport me to a whole other world, the vast and fascinating world of insects! This kit has all you need to get you started. While being suitable for use with children for family fun, it also includes the Collins Complete Guide to British Insects and Super Fine Pointed Forceps to accommodate a more delicate, detailed look into what you have captured.
Beth – Wildlife Equipment Specialist

NHBS In the Field – The Wi-Fi Bullet Wildlife Camera

Similar in design and set up to our very popular Wi-Fi Nest Box Camera, the Wi-Fi Bullet Wildlife Camera (3rd Generation) is cased in a weatherproof housing, allowing it to be set up outside to watch all the wildlife in your garden.

It is set up via the free accompanying app Green Feathers. This camera is designed to live stream footage to your smartphone or tablet via Wi-Fi and can be watched on a web browser (Google Chrome or Microsoft Edge) once having been set up via your smartphone, or can be viewed and recorded on a computer via OBS Studio, or even live streamed to YouTube.

For a reliable connection, the camera is mains powered and extension cables are available to make installation more flexible if needed. The footage is recorded to a micro SD card up to the size of 128GB. You can add several cameras to the app if you want to watch different angles in your garden simultaneously.

It is worth noting that these cameras run on 2.4GHz Wi-Fi. This is not usually an issue as most Wi-Fi routers run both 5GHz and 2.4GHz, but if you do need help with this there is an online help guide available.

How we tested

To check out how the Wi-Fi Bullet Wildlife Camera performs in a real life setting it was set up in an urban garden. It was placed on the outside of a greenhouse, facing different angles. We set the camera up to record when motion was detected. This is called event recording on the app but continuous recording is also a possibility. We enabled local recording to allow the footage to be recorded to the micro SD card.

We set up a motion detection alarm to alert us when motion was detected on the camera so that the footage could be watched live if wanted. We had this scheduled for between the hours of 7am and 11:30pm so that we would not be disturbed by notifications in the night. This does not stop the recording from happening at that time, but simply stops the notifications. The alarm sensitivity was set to ‘high’.

We predominantly viewed and recorded the footage on a smartphone but also tested out using OBS Studio alongside VLC to view and record the footage on a laptop, as well as watching the live feed on Google Chrome.

What we found

Setting up the camera was very quick and easy. Once we had downloaded the app it was quite a simple process and the app guides you through the setup process. If you do run into difficulties, there are a number of help guides online which include video tutorials.

Initially, we were not sure whether having the sensitivity set to high would result in lots of recordings triggered by wind, as the weather during testing was windy and autumnal, with hail showers and leaves falling from surrounding trees. We were pleased to find this was not the case. The only ‘false’ recording we experienced were spiders walking over the lens of the camera, too close for the camera to focus on, and as we had the camera set up facing the house, we noticed that at night the camera triggered when lights were turned on and off in the house when curtains weren’t drawn.

We did find that the motion trigger was more reliable when at a closer level to the subject. For this reason we predominantly kept the camera at a low height rather than placing it higher up and pointing down. We would recommend playing around with the location of the camera before permanently fixing it to a location using the included screws and fixing brackets. While wood pigeons and magpies triggered recording at distances of several meters, and cats (and people) even further, to the maximum tested distance of approx. 5 meters, we did find that smaller birds such as sparrows only triggered the camera when within 1 meter of the camera. For this reason, if you are wanting to use this camera for watching feeding stations for small bird/small mammals, we would recommend mounting the camera close to the feeding station or going for the 1080p HD Wired Outdoor Bird Feeder Camera if you would like a constant video feed to a TV (please note the Outdoor Bird Feeder Camera does not record sound).

We were impressed with the sound quality of the recordings. Although we did not manage to record a good video of the sparrows and starlings singing in the trees (the backlighting and distance to the tree was too far for good footage), they can be heard in other recordings. The camera does make some noise itself while recording but this was not too loud or distracting. We were also impressed with how little the noise of the wind was picked up by the camera.

The camera has an impressive viewing area, much larger than we were anticipating, however this did result in a bit of a fish eye effect to the footage. This was only really seen to affect the subjects being filmed when they were very close to the camera (as seen in footage of the cats having a good investigation of the camera).

The infrared, low light footage did kick in quite early some evenings, although these were particularly gloomy evenings. The footage was still nice and clear in the dark, as it was during the day, and the motion detection did not seem to be affected by whether it was day or night.

Exporting the videos from the camera was a little bit of a drawn out process as the videos are accessed via the playback function in the app while connected to the camera. From here you can see the event recordings as grey lines on the timeline on the bottom of the video feed. This timeline can be expanded and contracted using a pinching motion in order to allow easier navigation. When viewing an event recording that you would like to export/share, you can record it to the app by pressing the record button, and pressing it again to stop the recording. If you would like your saved recording to have sound, ensure that you enable sound while watching the playback before pressing record. You do this by clicking the speaker icon on the video. Once these recordings are saved to the app they can be found in your Photo Album which can be accessed through the app without internet connection. From here you can share them. Although this is a slightly long process, it does mean you can access your footage to share from wherever you are (as long as you have Wi-Fi) without having to remove the micro SD card, which is contained within the camera under a screwed latch in order to ensure that the camera is waterproof.

Being able to access the camera from a computer is also very useful and enables you to record footage straight to your computer rather than just to the micro SD card and app.

Viewing the camera from a web browser was also very easy to set up with the app by just scanning a QR code and confirming access via the app, to ensure it is a secure connection. You can also view multiple cameras in the web browser (single view and up to 9 cameras) so if you were to have multiple cameras, including a Wi-Fi Bullet Wildlife Camera and Wi-Fi Nest Box Camera, you can see them all simultaneously. This is a benefit over viewing in the app, as although you can add multiple cameras to the app, you cannot view them all at once.

Our opinion

This camera was easy to set up via the free app and provided hours of fun wildlife viewing. There are certain features that we think are worth bearing in mind when setting up the camera, such as positioning the camera close to where you hope to view smaller subjects, and we would also recommend that if you want to record specific behaviours or longer videos, to set the camera to continuous recording. This can be set up on a schedule so that the continuous recording only takes place in the timeframe you are interested in.

While the app was sometimes quite slow to connect to the camera, and the Wi-Fi connection to the camera was lost once (during 1 week of deployment), neither of these issues resulted in loss of video capture as the camera still records locally to the SD card regardless of whether there is internet connection. But the manufacturers are constantly working on improving the app, as it was only released earlier in 2021.

The Naturalist’s Microscope Guide Part 1: Stereo Microscopes

When thinking of the varied toolkit of the enterprising naturalist, a microscope is perhaps not the first thing that springs to mind. Nevertheless, for many entomologists, botanists and comparative zoologists, the ever-reliable 10× hand lens eventually proves insufficient. Indeed, many species of insect, lichen and fungi (among many others) are difficult to identify past genus or even subfamily without the use of more powerful optics. Animal scat, small mammal dentition and hair fibres can be likewise difficult to evaluate without suitable magnification. But researching the best optical equipment for your purpose can be a disheartening task, especially for naturalists who are likely to come across a wide range of resources for the engineer and medical professional, but sparse pickings tailored to their own specific needs.

For most naturalists, the 3D image and relatively low magnification of the stereo microscope (also called the low-powered dissection microscope) fits the bill nicely. However, with several big-name brands, a wide range of price points and numerous specifications available for uses across a plethora of fields, it’s useful to be armed with some background knowledge when choosing your own microscope.

Stereo Microscopes

Stereo microscopes are made up of several parts: most include a base with or without illumination, a pillar with an adjustable bracket for the head and a head comprising of two eyepieces and one or two objective lenses, depending on whether the microscope uses the Greenough or Common Mains Objective design (discussed below). Some also include a third eyepiece or ‘photo tube’.

Specifics regarding the different parts of the microscope will be discussed later, but for now, it is important to understand how magnification is calculated. The optics of a stereo microscope consist of two eyepiece lenses and one or two objective lenses with which they are paired. Each provides its own zoom – typically 10× for a standard eyepiece and 2× or 4× for the objective (although many objectives provide a range of magnifications between 2× and 4×, see below). The overall magnification is calculated by multiplying the objective and eyepiece lenses together, for example a system with 10× eyepieces and a 2× objective will provide a zoom of 20×. Some objectives have a dynamic zoom lens, as we’ll discuss later.

Optical Systems: Greenough vs Common Mains Objective

Stereo microscopes are grouped by the optical system that they use – Greenough or Common Mains Objective (CMO). Both systems have distinct advantages and disadvantages, so knowing the difference is vital.

A staple since its original conception in the 1890s, the Greenough Optical System works by angling two objective lenses towards each other to create a 3D image. The objectives have wide apertures for good light-gathering potential, providing a crisp, clear image. It is also cheap to produce, meaning that most entry- to mid-level stereo microscopes utilise this design. However, as the lenses are slightly tilted, the focus is not constant across the image – the outer left and right portions of the view are always slightly over-focused while the centre is clear. This is known as the ‘keystone effect’, and while it is often unconsciously corrected for by the human eye, it does cause the viewer to experience eye fatigue more rapidly than the alternative.

Introduced in the middle of the 20th century, the Common Mains Objective (CMO) system uses one objective lens that is shared by both eye pieces, allowing for exceptional light-gathering potential, and eliminating the keystone effect. However, the single objective leads to a problem known as ‘perspective distortion’, in which the centre of the image appears to be elevated like a fish-eye lens. Models that correct this can cost thousands of pounds, so for many naturalists, a high-end Greenough system is likely to be a better investment than a low-end CMO microscope.

Magnification

Once you’ve decided which system you would like to go for, consider the magnification. Most microscopes under £1,000 fall into the 20-40/45× range. Occasionally 60× models are offered in this bracket, but it’s definitely worth testing these before purchase as the extra range can come at the cost of features such as lens quality. Remember too that as zoom increases, the aperture of the lens decreases, making the image worse. For most insects above 2mm, a 20×-40× microscope should do the job. Groups that rely on minuscule features or genitalia dissections may require higher magnifications, but this often requires a better-quality microscope that uses high-quality parts to maintain a clear, bright image.

20x and 40x magnification of a Green Dock Beetle – Gastrophysa viridula

The cheapest stereo microscopes use a ‘fixed’ zoom system, with a single pair of objective lenses that provide one magnification, normally 20×. The objective (and sometimes the eyepieces) can be removed and replaced manually with a higher magnification alternative.

Models above the £150 mark generally use a rotating ‘turret’ system shared with compound microscopes. Two pairs of objective lenses are included and can be rotated into place, generally 2× and 4× allowing for 20× and 40× magnification. For the serious amateur naturalist looking to invest in a ‘workhorse’ style system, this is often the design to choose, and many professional entomologists and botanists spend years learning with such an optic.

Finally, stereo microscopes above around £300 generally use a dynamic zoom system. This allows the magnification to be altered across a range (normally 20-40×). The default 10× eyepiece can be swapped for a greater magnification if desired. Many also include a ‘click stop’ system for easy reading of the magnification without having to look up. The flexibility of these microscopes makes them the most popular choice among many naturalists.

The Head: Binocular vs Trinocular

This is simple but important to consider. While the binocular head is generally considered to be the default for stereo microscopes, the trinocular variant is extremely popular among researchers and anyone who seeks to document their microscopy: the addition of the third eyepiece (phototube) allows for a camera to be attached and images or video to be captured while the user is viewing the image. Many microscope cameras are designed to be used specifically with a phototube and will not function when used with a binocular head. Some, like the Moticam X3, can be used with either.

The Stand: Base, Stage Plate and Illumination

When choosing an illumination system, it is important to consider what you’ll be using your microscope for. You’ll often see plain (no illumination), halogen, or LED bases offered, with the plain option being the cheapest and LED the most expensive. Most illuminated bases offer both transmitted and reflected illumination, referring to the way in which light reaches the eye. The reflected system utilizes a light that shines straight down on the subject, reflecting the light off of the subject and into the user’s eye. This is the most commonly used design among naturalists, as the examination of opaque objects such as insects, plant material and mammal hairs requires the user to observe the sample’s upper surface.

Transmitted illumination utilizes a bulb beneath the sample, projecting light directly to the user’s eye, similar to a compound microscope. This is used in the examination of translucent samples such as aquatic invertebrates and some macroalgae.

This is also where stage plates come in. Sitting below the subject as the ‘background’ of the image, most microscopes come with opaque black and white options for use with the reflected illumination setting and a frosted glass option that light will shine through for use with transmitted illumination.

Motic ST-30C-6LED Stereo Microscope

Don’t immediately discount a plain base. Many naturalists prefer not to use built-in illumination that sits directly above the subject, as specimens that require the examination of fine details on the sample’s surface, such as many beetle species, can be difficult to ID under such a light. The best solution is to purchase a dedicated microscope illumination unit, a handy tool that usually includes two swan neck LEDs that can illuminate the subject from whichever angle is most auspicious. These aren’t cheap, but the cost of one is often covered by the money saved in purchasing a base without a built-in light.

Finally, consider the difference between halogen and LED illumination. For many purposes, such as the examination of bones, animal hair or water samples, this is irrelevant and largely comes down to a matter of taste. However, some materials are prone to desiccation under the heat of a halogen lamp. Therefore, particularly for entomological work and work involving live samples, LED illumination is often preferred.

Cardboard tree guards: a suitable and sustainable alternative to plastic?

In the forthcoming Winter 2021 issue of Conservation Land Management (CLM) magazine Jenny Price and Lyndsay Wayman-Rook describe how the Old Chalk New Downs project in Kent has been trialling biodegradable cardboard tree guards as an alternative to plastic. Here you can read a summary of the article.

The main purpose of a tree guard is to protect newly planted trees from browsing, but they also provide other benefits; they create a more favourable microclimate that helps to promote the growth of young trees and protect the plants from wind, competing vegetation, herbicides and water loss. Wooden and wire tree guards have been in use since the 1820s, but it wasn’t until the 1980s that plastic versions were first used. As a cheaper material compared to alternatives, plastic is now widely used for guards in planting schemes.

It has been predicted that between 1980 and 2020 over 200 million plastic tree guards were used, and with the UK government’s ambitious target to increase woodland cover by 19% by 2050, the rate of tree planting is sure to increase, as will the number of tree guards used. It is recommended that plastic tree guards are removed 2–3 years after their installation, but they are often left behind to degrade in the landscape, which can be both damaging to the wider environment (although the impacts of this are not yet fully understood) and to the tree itself. It is possible to recycle plastic polymer guards, but not if they have already started to break down or are contaminated.

The Old Chalk New Downs project, hosted by Kent County Council and funded by the National Lottery Heritage Fund, has been exploring alternative options to plastic tree guards. It first compared the costs of different materials, including plastic, cardboard and biodegradable plastic, and looked at the pros and cons for each guard type. For instance, one of the advantages of a cardboard guard is that it does not need to be removed after installation, but it may deteriorate a lot faster than other guard types, especially in particularly wet areas.

Biodegradable tree guard options Lyndsay Wayman-Rook

It was decided that cardboard guards would be used for this particular project, owing to their no-plastic design and availability. Between autumn 2019 and spring 2021, more than 9,000 trees with cardboard guards were planted across seven hedgerows at three different sites. How these fared was closely monitored, and the success rate of planting was high. One key aspect of this project was to gather feedback from landowners and contractors involved in sourcing and using the cardboard guards, and overall the comments were positive.

In the full article Jenny Price and Lyndsay Wayman-Rook discuss how the cost of tree guards made from plastic, biodegradable plastic and cardboard compare, and provide an in-depth overview of how cardboard guards performed when used for hedge planting, both in this project and in examples from elsewhere. They also include a summary of the feedback received from landowners and contractors, and clearly describe the advantages and disadvantages of different tree guard options.

Testing the Guide: Feathers

This is the first article in our new Testing the Guide series, in which we test the usability and application of various guides. Feathers: An Identification Guide to the Feathers of Western European Birds is a guide to over 400 European bird species, with an innovative key that allows for exceptionally precise identification by colour, feather structure and shape. This book also provides information on collection and conservation methods, as well as the locations of feathers on birds, all of which are clearly explained and richly illustrated.

This guide discusses the characteristics useful for identification, such as feather measurements, size variations and flight and tail feather shapes and adaptions. Also included are examples of identifiable body feathers and a beginner’s exercise in the identification of feathers from some common species. There are also species descriptions, including passerines, aquatic birds and birds of prey. The sequence of which these species are described, within families or orders, does not follow the usual systematic order: the author has attempted to describe groups that may be confused in close proximity due to their similar morphological characteristics or their presence in the same habitats.

This is a large-format guide, which may limit the practicality of taking it into the field, but it does allow the presentation of different feathers to be done in the clearest way. Therefore, this guide is most useful when feathers are collected or photographed. The more than 300 illustrations and 400 photographs facilitate the identification of many different feathers, often reducing the need for further, independent research.

Using the guide

Several feathers have been gathered by our colleagues around the UK, with notes taken of the location, date and habitats in which they were found, to aid identification. The guide details best-practice methods for collecting, labelling and preserving the feathers, which we found particularly useful. As the author suggests that larger feathers are more likely to be identifiable, and body feathers are much harder to distinguish, we chose to use the largest or most distinctive feathers we had collected.

Feather 1

The largest feather in our collection was found on the edge of town in Bovey Tracey in south Devon. It is a large, rigid feather that is dark brown in colour, with a white coloured section on the inner vane and darker brown irregular bars that end in specking on the white section. Using one of the many useful figures within chapter 2 (p. 17), as well as following the key located in chapter 3, we identified it as a notched, or fingered, outer primary feather from the right side of the bird. As the pattern matched several of the colour criteria within chapter 4, the process of determining identification took a little longer than expected. Using the colour criteria 4, 5, and 7, we were able to determine the feather is from a diurnal bird of prey.

Using the table for diurnal birds of prey in chapter 8, we noted that the size of the feather (approximately 13.6in / 34.5cm) and the patternation matched several species, including the common buzzard (Buteo buteo), the rough-legged buzzard (Buteo lagopus) and osprey (Pandion haliaetus). Referring to a number of the many beautiful photo plates and our own research, it is most likely a feather from the common buzzard, given its distribution, habitat and that they are much more common in the UK than osprey. Using the table in chapter 5 (p84), the placement of this notched primary feather is most likely between P10-P8, although it can be as far as P6 or even P5.

Feather 2

Using the information in chapter 3 again, we were able to determine that this second feather is also a large feather, most likely from the left side of the bird, as the feather curves to the left when looked at from above with the base towards us. Following the key was more difficult for this feather, as the answers were not as clear. However, we determined that this feather is a rectrix, or tail feather. As the width of both vanes are similar (outer: ~1.3cm, inner: ~1.2cm, although there is some degrading along the edge of the inner vane that may be masking its original width), the feather was most likely located towards the centre of the tail. As the rachis (or shaft) is curved and not fully straight, however, it is unlikely to have been located directly in the centre.

The feather is rufous and dark brown, with an irregular bar pattern that sometimes resembles vermiculation and gradually breaks down into speckling, with a more rufous tip. As the size of the darker bars is smaller, it would be referred to as brown bars on a rufous background. Using the colour criteria list in chapter 5, the feather size (~24.2cm / ~9.53in) is within the range of several species. As the feather is not velvety, we could discount owls, diurnal raptors or nightjars. As the feather is narrow and elongated, the chapter suggested looking at falcons, but we found that it did not match any due to the pattern and pointed tip. We then researched each species or species group that the size matched and determined that the feather is most likely a  tail feather from a golden pheasant (Chrysolophus pictus). This is an introduced species with several small, wild populations in areas such as East Anglia and in the Isles of Scilly, preferring dense woodland with sparse undergrowth. They can also be found in many aviaries and zoos, with a number of colour variations and hybrids, particularly with the Lady Amherst Pheasant (Chrysolophus amherstiae). Their feathers are often used by florists, as well as crafters to decorate heads, earrings, clothing and even lures for fly-fishing.

Feather 3

Bright, uniquely colour feathers have a higher chance of being identifiable to a species level. This feather was found in the wetlands around Chew Valley Lake reservoir in Somerset. The rigidity of this feather shows this is also a large feather, and the curve suggests it comes from the right side of the bird. Following the key in chapter 3, we determined that this is a secondary feather.

Using the colour criteria in chapter 5, the metallic dark blue colouration of the feather and the length (12.2cm / 4.8inchs) matches a number of species, but the handy colour plate on the next page allowed us to determine that this feather most likely came from a mallard (Anas platyrhynchos). The blue colouration makes up part of the speculum, the contrasting patch of colour on the bird’s wings. Referring to the species description and feather spread on pages 304-5, the feather is most likely a middle secondary, although exact positioning would be difficult to determine with a lone feather. The well defined dark blue colourations suggest between S3-S10. There are also a number of hybrid Anas species and the identification of these through feathers is unlikely.

Our opinion

There are several limitations to identifying feathers, as individual variability in size and colour are common amongst species, and feathers can be similar between species within the same family or that occupy the same habitat or niche. The author suggests that only a small fraction of feathers lost by birds are identifiable, therefore the practical applications of this guide are restricted. However, we were able to use this guide to identify many of our larger or more unique feathers, including the common kingfisher (Alcedo atthis), European goldfinch (Carduelis carduelis) and barn owl (Tyto alba).

It is relatively straightforward to identify where on the body the feathers come from and, while the feather can sometimes match several colour criteria, it is also quite easy to identify a list of potential species matches. From here, the size of the feather can help to narrow the list down, although this is not always possible. Using the various species descriptions and feather spreads in chapter 8, your own research and knowledge of the habitat and location that the feather was found in and the distinctive markings or colouration on the feather itself can all help you to identify your feather to species level. We also found that, while our first feather did not resemble the osprey spread in the guide, it did match feathers from other collection photographs we found in our own research. Therefore, while this guide is incredibly helpful in determining the type of feather and the list of possible species, we encourage researching any potential match both with the guide’s species descriptions and through independent research. Feathers: An Identification Guide to the Feathers of Western European Birds is a novel introduction to the world of identifying feathers, which can be an engaging and entertaining way to increase your knowledge of Europe’s birds.
