A new study has found plants that humans don’t need will ‘lose’ in the face of humanity. Around 46,292 species out of the 86,592 vascular plants studied were categorised as ‘losers’ or ‘potential losers’, many of which are not considered to be useful to humans. Due to this, plant communities of the future will likely be more homogenised. The findings cover less than 30% of all known plant species, highlighting that more work is needed in this field.
A project by the environmental group ‘The Nature Conservancy’ aims to undo the ‘degradation’ of a Kentucky stream. The Long Branch stream was straightened decades ago, altering the flow and natural biodiversity along with increasing erosion. Contractors had previously re-created the natural bends, pools and riffles of the stream, placing rocks, tree root wads and burlap material at some places along the banks. Workers are now planting trees along a section of the stream with the hopes of providing better habitat for a small fish called the Buck darter, which is found only in this watershed.
The UN has launched biodiversity talks on a deal to protect nature. The negotiations began in Geneva on Monday with the deal due for approval later this year. Almost 200 countries plan to adopt a global framework to safeguard nature by mid-century, with a milestone of 30% protected by 2030.
A Squat lobster was seen on Shackleton’s Endurance ship, potentially the first Munidopsis species recorded in the Weddell Sea. It is hard to be certain due to the resolution of the released images but Dr Huw Griffiths from the British Antarctic Survey (BAS) suggested the animal could be from the Munidopsis genus, which contains over 200 known species.
As spring starts getting into swing, it’s time to begin looking forward to the summer birding season. With the gradual relaxation of international travel rules and things seeming to get safer, many of us are considering birding trips for the first time in years. Whether the venue be the sea cliffs of Anglesey, the wide mud flats of Essex and Suffolk or the dramatic heights of the Pyrenees, having the right kit for the job is at the forefront of every birder’s mind.
Kowa Optics holds an interesting place among birding brands. In the UK, at least, they have seemingly not had the name recognition of other big-brand, high-end optics suppliers until recently, and yet their reputation among serious hobbyists is largely unrivalled. Uniquely, Kowa have pioneered the construction of spotting scope lenses from pure fluorite crystal, a hard-to-work-with material that is peerless in its light dispersing properties. Though this technology comes with a hefty additional price tag, the quality of image that it produces has made waves across the birding sphere.
In addition to their high-end, pure fluorite optics, Kowa offers a range of more entry level equipment for those looking to acquire a quality scope or pair of binoculars at a competitive price. Among their more popular offerings are two compact spotting scopes – the entry level multi-coated TSN-500 series and the high-end, pure fluorite crystal TSN-550 series. The TSN-500 20x-40x range is a veteran of the birding market, having been around in one form or another for years now, but are updated fairly regularly in keeping with new technological advances. Compact, robust, and with a great reputation, they have a strong appeal for travelling birders and outdoor sportspeople. We were thrilled to get our hands on the Kowa TSN-501 – the angled model in the range – to see how it performs.
First Impressions
When the box is opened, the first thing you notice about the TSN-501 is how truly compact it is. Somehow, promotional images just don’t do it justice. At less than 25cm long and weighing in at just 400g, portability certainly won’t be an issue. There was much oohing in the NHBS office when it was unboxed.
The plastic casing is good quality and feels pleasant in the hand. The neoprene cover that can be purchased separately is well worth it too, providing that little bit of extra protection that will allow you to carry the TSN-501 around with confidence.
The lens caps are secure, though they don’t have the provision to be attached to the body when not in place. The focus wheel is placed comfortably so that the user can turn it while steadying the scope with their palm. It’s beautifully smooth, with no discernible kickback and minimal resistance. The image can be magnified between 20x and 40x by rotating the eyepiece – this was quite stiff on the model tested, but while this could be frustrating it does ensure that the zoom doesn’t shift during use. There are no click-stops, as is fairly usual among spotting scopes, but two white markers indicate when the magnification is at 25x and 35x respectively.
The extendable eyecup is made from softer rubber and is comfortable on the eye. It is also fine enough that it is possible to use a phone or similar device to take photographs through the lens at a pinch. This can be made easier with Kowa’s extensive range of digiscoping accessories.
How We Tested
One rather cold day in March we took the Kowa TSN-501 angled scope down to the River Dart that runs alongside NHBS’s offices in Devon. Alongside some casual birding while we had the chance, we set up a more formal test of its capabilities, with natural markers chosen at intervals to see how the optics perform at different ranges. We also made sure to note how performance differed when the objects viewed were backed by the bright sky, reflective water and darker ground. Effects such as chromatic aberration – the fringing of a dark object with a faint halo of colour – can be particularly pronounced against bright backgrounds, so it was important to test the unit in a range of conditions.
We used a Velbon CX 444 tripod – a rather heavy model that felt like overkill for such a light scope! Still, it attached painlessly and securely, thanks to Kowa’s universal tripod mount, and helped offset any shaking that the wind might have caused.
What We Found
The Kowa TSN-501 performed well for us, providing a consistently clear, bright and fairly aberration-free viewing experience across all conditions tested. Unavoidably, it does have a small field of view, especially when zoomed in to 40x, so it’s best used in conjunction with a pair of binoculars.
That said, the quality of the image really can’t be overstated for a scope of this price. I found it to be easily comparable with full-size scopes of a similar price and probably rivalling those of higher price brackets too. It doesn’t quite measure up to the quality of ED (extra-low dispersal) glass but is about as good an image as you’ll find in non-ED optics. The colours are well represented, and the image is clear and bright with excellent contrast. You’d struggle to follow a bird in flight, and there is noticeable distortion around the periphery of the image, but for observing stationary or slower moving subjects, it makes an ideal tool. I had no trouble following mergansers as they moved across the surface of the water, or wagtails hopping across the weir. During the trial, I wondered whether it might especially suit ornithological surveyors or other professionals who need to identify species rather than make detailed observations at the highest image quality possible.
It is waterproofed and nitrogen-filled, so regular use in adverse conditions shouldn’t be an issue, and its compact nature makes it ideal for carrying in a kit bag. As stated earlier, it really makes a difference to have the neoprene case, providing an extra level of protection when travelling over rougher ground.
Our opinion
The Kowa TSN-501 is a really quite remarkable little piece of kit. For a reasonably priced, compact travel scope, it provides a clear, bright image, despite the small lens aperture. Although it struggles at long range and in conditions where a wide field of view is necessary, it represents an excellent choice for the travelling birder on a budget.
It’s easy to see why Kowa have built such a reputation among birders. Above all else, the little TSN-501 represents impressive value for the money spent. Plenty of much larger scopes for the same price or higher would struggle to offer the same image quality, and few compact scopes come anywhere close. It will never be a substitute for a good-quality, full-sized spotting scope with ED optics, but among non-ED optics, it stands head-and-shoulders above the crowd. If you are looking for something reasonably priced to put in hand luggage, transport in the glove compartment during a long trip or just to offer a bit more power than a pair of binoculars while remaining portable, there aren’t many better choices out there.
Kowa TSN-501 can be found here. Our full range of spotting and field scopes can be found here.

In response to the growing climate and biodiversity crisis, SCOTLAND: The Big Picture is working to drive the recovery of nature across Scotland through rewilding. Using positive storytelling, they hope to inform and inspire change, while also enabling practical rewildling through partnerships and collaborations. They see a role for everyone in creating a wilder Scotland, with a vision of a vast network of rewilded land and water where wildlife and people flourish.
Executive Director, Peter Cairns, has kindly taken the time to answer a few questions for us.
Could you tell us about the work that SCOTLAND: The Big Picture does and how the charity began?
Our core team has been involved in environmental communications for more than two decades so when the rewilding story really started to gain momentum in Scotland, probably about a decade ago, we were well placed to document it. The ‘R’ word (rewilding) remains contentious to this day, but as we embraced it at an early stage, we gradually – and unwittingly – became the voice of the movement, or at least one of them. That gave us a platform and in 2019, we became a fully-fledged charity, working to drive the recovery of nature across Scotland through rewilding, in response to the growing climate and biodiversity crises.
One part of your vision is creating a future for Scotland where people thrive, but development and industry can sometimes be in contention with wildlife. How do you think a nature-based economy could allow for long-term restoration of habitats without negatively impacting communities?
Pitching people against nature helps neither. We need to look for new ways to marry our economic systems with our ecological systems.
We believe the transformational recovery of nature can only be achieved with the support of local communities – rewilding will only work if people can see social, cultural and economic benefits that work in tandem with ecological recovery.
The original principles of rewilding were founded on the ‘3C’s’ – cores, corridors and carnivores, and there’s no reason why such a model can’t be explored in Scotland. ‘Cores’ means areas that are effectively given over to nature, allowing natural processes to shape and govern the land. Around these could be buffer zones, where a high degree of ecological functionality is maintained, but a range of nature-based economic activities, such as payments for natural capital, wild produce and diverse nature-based experiences, help support vibrant communities.
SCOTLAND: The Big Picture was a founding member of the Scottish Rewilding Alliance, how have you found the reception of this alliance amongst organisations? Are they generally in favour of large-scale rewilding in Scotland?
Rewilding has come to mean different things to different people and that can be a challenge, but it also provides opportunity for it to be rolled out at different scales and settings, while still making a valuable contribution to nature recovery. The members of the Scottish Rewilding Alliance are all at different stages on their journey, but all recognise that the traditional models of conservation have failed to arrest and reverse ecological decline, and are committed to a fresh, more ambitious, more holistic approach.
Outside of the Alliance, there is a growing appetite for change across Scotland, as land managers look at the social, political and economic horizon, and realise that business as usual is not an option.
Your upcoming feature-length documentary, Riverwoods, reveals the perilous state of Scotland’s salmon and presents the inextricable relationship between fish and forests. What are the main threats to this species and Scotland’s rivers, and why is salmon such a valuable species for forest ecosystems?
Atlantic salmon is a modern-day canary in the mine – an indicator of ecosystem health. The reasons for its spectacular decline, like so many species, are many and complex, and this film doesn’t attempt to address them all. Instead, Riverwoods tells the story of salmon – young salmon in particular -in our rivers, and carries a simple message: The health of our rivers and all the life within them, is directly dependent on the health of the landscapes through which they flow.
Perhaps to set the scene, I can quote from a recent article we produced on this very subject:
6,000 years ago, a rich, dynamic woodland ecosystem stretched across 60% of Scotland’s land area. These were diverse forests of Scots pine, oak, rowan, birch, aspen and willow; a complex community of shrubs and bushes, tall trees, tiny trees, dead and dying trees, all intertwined in a constantly evolving system.
Flanking Scotland’s rivers and lochs, these woodlands were shaped by beavers, creating fresh coppice growth, new wetlands and backwaters, raising the water table and toppling insect-laden trees into and alongside the river. The decaying timber provided food and sanctuary for more invertebrates, as well as casting dappled shade across the river’s surface.
Spent salmon, exhausted after an epic journey from freshwater to sea and back again, fed brown bears, wolves, eagles, ospreys and otters, before the precious marine nutrients found in their carcasses, were taken up by the soil nourishing fresh plant and tree growth.
In other parts of the world, the connectivity between river, forest and ocean, and the bountiful runs of salmon that still persist, creates a living, breathing, working system. Here in Scotland, just 3% of our native forest remains, clinging on in isolated, lonely fragments and despite their reputation for beauty and drama, the glens through which our rivers run, are often bare and treeless, reflecting the centuries of ecological decline that we have come to accept as normal.
How do you think Scotland’s river catchments can be restored? What changes need to take place?
Fundamentally, we need to perceive and manage river catchments as a complete ecological system and not as a series of individual species and habitats. No species exists in isolation and again, the health of our rivers is dependent on the health of the surrounding landscape.
More immediately, many of Scotland’s rivers are getting warmer, some approaching the lethal limit for young salmon, so these fish are crying out for the trees that once shaded and nourished them. The roots of trees like alder and willow, which can live in the water, protect fish from the sun and provide hidey-holes during high flow events. Tree roots help stabilise riverbanks and woody structures like fallen trees in the river, create deep pools and riffles providing salmon with the structurally diverse riverbeds they favour. A lack of overhanging trees also reduces insect numbers which in turn, means less food falling from branches into the mouths of hungry fish.
For people inspired by your work, how would you suggest they get involved?
We normally recommend 3 actions:
WILD YOUR SPACE: It’s easy to imagine rewilding at a landscape scale but this is a journey that offers space for everyone. Parks, gardens and public spaces can all make a valuable contribution to a landscape rich in nature and passionate individuals and communities are already working together to create more space for bats, bees and butterflies. Everyone can get involved.
MAKE SOME NOISE: Rewilding is as much a change in mindset as it is a physical change to the land or sea, so it’s good to talk. Most people don’t realise that Scotland has become a nature-depleted nation. Talk to family, friends and work colleagues about the potential of a rewilded Scotland for nature, climate and people. Encourage them to join our Big Picture community.
PUT YOUR MONEY TO WORK: There are many ways to invest in rewilding. You can support businesses such as local farms that are working to restore wildlife, or nature tourism operators who donate part of their revenues to rewilding. And of course, you can help make more rewilding happen by supporting organisations like SCOTLAND: The Big Picture.

A number of previously locally extinct mammals in the Sturt National Park, New South Wales, are now thriving in their feral-free zones, and researchers are amazed by how quickly they have repopulated. With the exclusion of feral cats from enclosures, mulgaras, bilbies and Shark Bay bandicoots have all seen population increases since their translocations. There are also plans to reintroduce another species this year, the golden bandicoot. While this is promising news, ANU ecologist professor David Lindenmayer stated that, while the feral-free zones are helping to conserve animals, both state and federal governments need to do more, including increasing funding and ensuring collaboration between scientists, conservation groups and politicians.
A new report from IPPC warns that many of the impacts of global warming are now “irreversible”. Four months on from COP26, this is the second of three reviews from the world’s foremost body of climate researchers, and looks at the causes, impacts and solutions of climate change. It shows that climate change is impacting humans and other species far worse than previously indicated, with more than 40% of the world’s population “highly vulnerable” to climate. However, authors of the report say that there is still a small amount of time left to avoid the very worst.
Countryside Management Association (CMA) is the largest organisation in England, Wales and Northern Ireland that supports the work of conservation, access and recreation professionals in the natural greenspace and countryside sector. They also have close ties to the Scottish Countryside Rangers Association (SCRA), Scotland’s own association.
Through networking, training and continuing professional development, CMA supports and champions the development of staff, students and volunteers that are involved in the management, interpretation and public enjoyment of natural greenspaces and the countryside. They promote the value and importance of these areas and their management to the general public, government and other organisations, while also providing organisations who are involved in management with helpful and relevant information.
Last year, the CMA ran a photo competition celebrating the work of professionals in the field and shared inspirational photos of staff and volunteers undertaking work to protect, enhance and interpret these important areas. Participants were encouraged to submit images of work involving anything from habitat management, estate work, and wildlife survey and monitoring to leading events and school visits, and engaging with visitors and volunteers. The competition ran from May 2021 to 7th January 2022. We teamed up with CMA to offer some fantastic prizes: a £100 voucher for first prize and £50 vouchers for two runners-up.
Results
Winner: Robert Ballard
The winning entry was taken by Robert Ballard, a ranger at Stover Country Park near Newton Abbot in Devon. His black and white image is a portrait of several volunteers undertaking some pond maintenance. Ponds and lakes are important habitats, supporting a wide range of species. Maintaining and enhancing them has a number of ecological benefits, including increasing wildlife diversity, improving water quality, reducing pond edge or lake shoreline erosion and creating better habitats for aquatic species.
First runner up: Jo Maddox
First runner up was Jo Maddox’s image of conservation work with a city background. CMA liked this image as they are currently seeking to promote and represent greater diversity in their membership, and to highlight urban greenspace management in particular. Urban green spaces, such as gardens, parks and woodlands, provide a vital habitat for wildlife, as well as numerous benefits to people living in urban areas. The management of these areas can help to improve and maintain ecosystem health and biodiversity.
Second runner up: Aam Hersey
Second runner up was Aam Hersey’s socially distanced hedge workers, which CMA thought was of the moment. Hedgerows are dynamic and invaluable habitats, providing food, shelter and breeding sites for species such as yellowhammers, great tits and dunnocks. Hedgerows are made up of a wide range of flora groups, often thought as different layers, including the shrub layer, tree layer, base, margin and ditch. Woody species like hawthorn, blackthorn and hazel make up the tree layer. Smaller woody species, shrubs and climbers, for example bramble, honeysuckle and ivy, are part of the shrub layer, which can also include young trees. The base, margin or ditch parts of a hedgerow can be bare ground, grass or be occupied by wildflowers such as herb robert, wood sage and red campion or thick herbaceous vegetation like cow parsley and common hogweed. Each of these components can support different wildlife, therefore hedgerow management is vital to maintain and promote this biodiversity.

Trail cameras are a widely popular solution to monitoring elusive or nocturnal wildlife for both professionals and wildlife enthusiasts alike.
Modern trail cameras tend to be very reliable and are designed to be highly user-friendly. However, there are a few things we would suggest to ensure your camera performs to the best of its ability. These are the initial steps we advise to take if you are experiencing issues with your camera, and these can often resolve or at least identify the problem. For tips on how and where to set up your trail camera, check out part 2 of this series.
Batteries
Try a set of new batteries
Most minor troubles with trail cameras are due to the batteries not providing enough power. This can be down to the type of batteries being used or simply that they are getting low and need replacing. If you are experiencing black night-time images, short night-time videos, or no night-time captures are being taken at all then the first thing to check should be your batteries.
Battery meters on trail cameras are not always accurate, so we suggest checking your batteries with a tester/voltage meter prior to use if possible. This is particularly important for professional usage.
Choose Lithium batteries if at all possible
We, and many trail camera manufacturers, highly recommend Lithium batteries as the best option for performance. The Energizer Ultimate Lithium are particularly well thought of, and as such are included in our Starter Bundles (see individual product pages).
Lithium batteries have a significantly longer lifespan than most other types e.g. alkaline and rechargeable NiMH, while also performing more reliably for a number of reasons that are explained below.
Trail cameras generally require 1.5 volts (V) from each AA battery to perform at their full potential. When the voltage begins to drop you may start experiencing issues such as those mentioned above. One of the main benefits of Lithium batteries is that they maintain their voltage until the end of their usable lifespan when it then rapidly drops off. In contrast, Alkaline batteries experience a pretty consistent voltage loss throughout their lifespan, meaning they can drop below 1.5V rather quickly after deployment.
Unfortunately, we do not recommend rechargeable AA batteries (NiMH). At only 1.2V, rechargeable batteries are unlikely to power the camera reliably or for long. If rechargeable batteries are still the preferred option, it is important that the batteries offer at least 2500mAh. Some camera models have been designed to work more effectively with rechargeable batteries, for example the Recon Force Elite HP4, however the performance is still unlikely to be comparable to use with Lithium batteries.
Be prepared for batteries to die more quickly in cold weather
During colder winter months, you should expect your batteries to discharge more rapidly and the battery life to therefore be reduced. At lower temperatures the chemical reactions accruing in the battery are slowed down, diminishing its power.
Alkaline batteries are particularly troublesome in this regard as they contain a water-based electrolyte, which means they seriously struggle as temperatures approach freezing. Again, Lithium batteries are the superior choice and can withstand significantly colder conditions while still performing fantastically, albeit slightly diminished in comparison to use in more mild conditions.
SD cards
SD (Secure Digital) cards are available in a wide variety of sizes and speeds. Generally speaking, we find a 32GB, class 10 SD card a very suitable choice, and this is what is included in our trail camera Starter Bundles. It is worth reading the manual of your chosen trail camera to check for any compatibility requirements or maximum size capacities.
Format your SD card
Formatting your SD card is an important step when starting with a new camera, or if experiencing SD error alerts on your camera. It is important to be aware that formatting your card will erase all data, so any important videos or images should be transferred elsewhere beforehand.
There are two options for formatting your SD card: using a computer with an SD card reader or via the trail camera itself. When using a computer, simply look for the SD card in your file explorer/file finder, right-click and select ‘Format’. The majority of trail cameras also provide an in-built option to format your SD card via the settings menu. For the brands we offer, the menu options are likely to appear under the following titles (or similar):
Browning – ‘Delete all’
Bushnell and Spypoint – ‘Format’
Check your SD card is not locked
A common error message seen with trail cameras is ‘missing SD card’. If an SD card is inserted in the camera but the error message is showing nonetheless, it is worth checking if the card is ‘locked’.
Modern SD cards include a small plastic lock switch (seen on the left side of the image) that allows the user to prevent any data being written or images deleted from the card. Simply slide the switch into the unlock position and check if the error message disappears when you re-insert the card.
Settings
Return the camera to the default settings
When a trail camera is not behaving as it should or how the user would like, we would recommend resetting the camera to the original factory settings. This can be easily done through the menu on the trail camera and is likely to be named ‘default settings’, ‘default’, or similar.
Reformat your SD card (and check it is not locked!)
Reset your camera to its default settings

We have reached the end of the 43rd Big Garden Birdwatch, which took place between Friday 28th and Sunday 30th January. Run by the RSPB, it’s one of the largest citizen science surveys in the UK and encourages the public to record their garden birds and submit their results. Over a million people took part last year, recording over 17 million birds, helping the RSPB gain an accurate understanding of how bird populations are faring.

There’s still time to submit your results if you took part over the weekend, the final date to let the RSPB know what you saw is 20th February. But don’t worry if you didn’t get to take part this year; it is an annual event, so make sure to look out for it next year! To take part, all you need to do is spend 1 hour counting the birds that land in your garden, balconies or outdoor spaces. It’s important to count the highest number of each species, rather than the total amount you see over the hour, otherwise, you might end up counting the same individual twice. You can submit your results online on the RSPB website. To help you identify certain species, take a look at our range of field guides, as well as our previous identification guide blog posts here.
Over a million people took part last year, recording over 17 million birds, helping the RSPB gain an accurate understanding of how bird populations are doing. They now have over four decades of data, showing the trends in UK bird populations, which helps them which species are faring ok and which are in decline. Both goldfinches and great tits have benefited from gardens, with goldfinch populations in gardens increasing by 50% over the last decade. However, the Big Garden Birdwatch has also shown that thrushes and greenfinches sightings have decreased, with greenfinch recordings down by 65% and thrushes by 78%. We hope that more people have taken part this year, and, as always, many of our staff got involved. Scroll down to see what we found.
We’d also love to see what you’ve spotted if you took part – let us know in the comments below.

Our total
Total individuals per species 2022
In total, we saw 16 different species and 105 individuals across our 5 gardens. Our most common bird species were starlings (Sturnus vulgaris), blue tits (Cyanistes caeruleus) and woodpigeons (Columba palumbus). Last year, our most common were long-tailed tits (Aegithalos caudatus) and jackdaws (Corvus monedula), and in 2020 it was house sparrows (Passer domesticus), followed by great tits (Parus major). It will be interesting to see how our results compare to the overall results of this year’s Big Garden Birdwatch.

Tree surgeons in Barcombe save endangered bird’s habitat. The company tasked with trimming treetops at Barcombe’s disused railway station in East Sussex worked with Barcombe Community Wildlife Group to help maintain the important breeding ground for endangered nightingales. The tree surgeons enhanced the habitat for nightingales and the insects they feed upon along the 33,000-volt 3km route, while still maintaining the power network. The trees and surrounding vegetation were recycled into woodchip mulch to use in the soil, and wood stacks were also made for the area to encourage wildlife.
Grey wolves have had their federal protections restored across much of the US. In 2020, the U.S Fish and Wildlife Service (USFWS) decided to delist wolves from the Endangered Species Act. However, it was suggested by wolf advocates that the USFWS failed to show that wolf populations could be sustainably managed by states in the Midwest and parts of the West without federal protection. A US District Judge stated that the USFWS had not considered species-wide recovery and instead focused on individual recovered populations, such as in the Northern Rockies. Thus, he ruled to immediately restore federal protection to wolves in the Midwest and parts of the West.
Paignton Zoo is freezing the DNA of endangered animals in hopes to save them from extinction. In a project called “Noah’s Ark of DNA”, the zoo has frozen samples from 82 species, including mouse deer, Humboldt penguins and panther chameleons, with the aim of collecting samples from hundreds of the world’s 40,000 endangered species. This is one of several DNA preservation projects in the UK, acting as a potential safeguard for many species.
A study has found that air pollution makes it tough for pollinators to stop and smell the flowers. Researchers have found that common, ground-level air pollutants react with floral scents, leading to reduced pollination. The presence of nitrogen oxides and ozone resulted in up to 90% fewer flower visits, as well as one-third less pollination than in a smog-free field. The concentrations of pollutants used in the study were less than half the average levels of air pollutants considered safe under US law.
Invasive non-native species cost the UK approximately £122 million per year and are a huge driver of biodiversity decline worldwide. There are a surprising number of non-native reptile and amphibian species in the UK, from non-breeding released pet terrapins to established populations of midwife toads, although the impact of some of these species on our native wildlife is not yet fully understood.
The first part of the 2022 Herpetofauna Workers Meeting included a number of talks that discussed the latest research on introduced reptile and amphibian species in the UK, including the Aesculapian Snake in Wales and the Alpine Newt in Northern Ireland. We were pleased to be able to attend and take part in this event again this year, and below is summary of some of the fascinating talks from what was an interesting and informative afternoon.
The Aesculapian Snake
The Aesculapian Snake Zamenis longissimus is a non-venomous species found across southern and central Europe, with relic populations in northern Europe. Although not native to the UK, there are two known introduced populations, one on the grounds of the Welsh Mountain Zoo in Colwyn Bay, Wales, and another along Regents Canal in London. There is also a possible third population in Bridgend in South Wales, but this is unconfirmed as of yet. Tom Major from the University of Bangor is using radio telemetry to study the population at Colwyn Bay to understand how this species is surviving, and he has gained some incredible insights into the ecology of the Aesculapian Snake over the past year.
While tracking nine adult individuals he found that on average the snakes travel the distance of approximately three and a half rugby pitches, and tend to visit one particular place where they stay for roughly four days before setting off again. This seemed to be anywhere that was warm and dry, from a chapel roof to a compost heap. By the end of the tracking period four individuals were still alive. Buzzards, stoats and cars were the reasons behind a few of the deaths, but one interesting cause was cannibalism – one tracked snake was recorded being eaten by another tracked individual, the first known occurrence of this behaviour in this species.
Turtle Tally
Reptiles and amphibians are becoming increasingly popular pets, but a lack of knowledge of their complicated care requirements or an unexpected change in an owner’s circumstances, amongst other reasons, can lead to the intentional release of these exotic animals into the wild. In order to gain an understanding of the distribution and impact of released pet terrapins in the UK in particular, Turtle Tally UK is a nationwide citizen science project that calls for the general public to submit their own terrapin sightings and photos. During her talk, Turtle Tally project lead Suzie Simpson shared some of the findings since the project began in 2019. Each year since has seen an increase in the number of sightings submitted, and hotspots have become apparent in London, Cardiff, Swansea and Liverpool. Yellow-bellied and Red-eared Slider were amongst the most frequently recorded species, and generally only one individual was recorded per sighting.

When they are out of water, terrapins are usually spotted on logs, rocks and even litter – any raised platform in a water body that they can use for basking. This also includes the nests of waterbirds, but so far there has been no evidence that these terrapins show signs of aggression to waterbirds, or that they predate on chicks. Some species, such as snappers and soft shells, would be more of a concern, however, and the Turtle Tally UK project aims to continue to collect data to further our understanding about the impacts of released pet terrapins on native wildlife. Egg laying has been observed on occasion, but due to the UK’s cooler climate, reproduction is very rarely successful. However climate change could result in more suitable conditions for breeding in the future.
The Alpine Newt in Northern Ireland
The Smooth Newt is Ireland’s only native species of newt and, with its distinctive orange belly and spotted pattern, it is easily recognisable. In September 2020, a strange looking newt was found in Northern Ireland during a bat survey. With a similarly orange belly, but without the spotted markings on its underside and darker in colour, this particular individual did not match the description of a Smooth Newt. It was soon confirmed that this was an Alpine Newt, a species found in Europe but not native to the UK. The discovery of this species is a particular concern as the Alpine Newt is a known vector of chytrid fungus. Rob Gondola, Ryan Boyle and Éinne Ó Cathasaigh provided an update of the consequent Alpine Newt surveys that took place during the following summer in 2021. Thankfully, all the swabs that were taken to test for diseases have come back negative, and they were able to determine the presence of two established populations. Further surveys and testing are hoped to continue in 2022.
There were a number of other talks throughout the conference, from the ongoing study of midwife toads in the UK (another non-native species that was introduced over 100 years ago) to the impact of climate change on UK herpetofauna. This was an enlightening and fascinating afternoon and we look forward to Part 2 of the 2022 Herpetofauna Workers Meeting later on in the year. The date and location of the event will be confirmed at a future date, but any details will be made available on the ARC or ARG UK website. A recording of Part 1 will also be made available – keep an eye on the ARC website for further details.
