Following the acquisition of EFE & GB Nets earlier this year, NHBS now manufactures a wide range of plankton nets at our workshop in Devon. Nets are available with an opening diameter of 250mm, 300mm or 500mm and with mesh sizes ranging from 10µm to 500µm.
250mm and 300mm diameter nets
250mm and 300mm diameter nets have a stainless steel frame to which a 500mm long bag is attached. They are supplied with a harness and seven metre long towing line which can be used to tow the net behind a boat or from a suitable bank or jetty.
The standard cod end is fitted with a filter in the same mesh size as the main part of the bag. However, various alternatives can be selected at the time of ordering. Options include a clear extension tube, collecting bottle, tap valve or large filter fitted in place of the standard filter. It is also possible to have weight loops added to the end of the net (weights not included) or a stainless steel swivel to be used on the harness in place of the standard nylon ring.
The heavy duty upgrade uses heavy duty nylon for the net collar and cod end collar and also includes fully taped seams.
500mm diameter nets
500mm diameter nets have a stainless steel frame and 1900mm long bag and a three point harness with swivel connector. All seams are reinforced and the collar is made from industrial nylon for added strength and durability. The cod end of the bag is fitted with a heavy duty screw-on filter in the same mesh size as the bag. This net is not supplied with a towing rope and so users will need to supply their own rope or chain which can be fitted to the harness.
As with the smaller plankton nets, various adaptations are available in order to create a net which is suited to your sampling needs. A flexible cod end extension allows a greater sample volume to be collected and also lets you connect a different filter type. A replacement cod end cap provides a closed ended option and results in a sample size of 700ml and a quick release bag is ideal for collecting fry or elver or for when a rapid changeover of bags is required.
Net bags and the educational plankton net
As well as standard plankton nets, we also stock a range of plankton net bags designed to fit onto the professional hand net frame. These fit onto the frame in the same way as the standard hand net bags, and have a detachable screw-on filter in the centre. An educational plankton net with 150µm mesh is also available for school use or for those who require an economical net for trial sampling.

About the Butterfly Conservation and NHBS partnership
Butterfly Conservation is the UK charity dedicated to saving butterflies and moths. Butterflies and moths are key indicators of the health of our environment. They connect us to nature and contribute to our wellbeing. With over 30 nature reserves across the United Kingdom, Butterfly Conservation works in many ways to conserve butterflies and moths and improve their habitats, creating a better environment for us all.
“NHBS offer the world’s largest selection of wildlife, science and conservation books, and have expanded their range to include ecology and biodiversity survey equipment and gifts. They have a fantastic reputation for customer service and quality items, and we are thrilled to be able to offer our members and supporters the chance to purchase a wider selection of items whilst still being able to raise vital funds for our conservation work.”
NHBS have worked with Redfern Natural History Productions for many years now and we were delighted to help out with this special project when Stewart McPherson approached us about it.
Thanks to the very generous sponsorship of Lord Ashcroft, Redfern were recently able to donate one copy of Stewart McPherson’s latest book Britain’s Treasure Islands: A Journey to the UK Overseas Territories to every secondary school in the UK and across the overseas territories. At NHBS we organised the packing and delivery of each of these books, which in total was 5250 copies.
The UK Overseas Territories are home to thousands of species of animals and plants in habitats ranging from coral reefs to tropical rainforests, polar landscapes and deserts.
In Britain’s Treasure Islands (aired as a three-part documentary on BBC4 in April, with the book accompanying the series), Stewart McPherson showcases this incredible variety of wildlife, explores the human culture and history of the islands, and documents his adventures in these remarkable lands.
This is a monumental work of over 700 pages, with more than 1,150 full colour images and 17 specially-commissioned gatefold maps on parchment paper showing the geography of each territory.
To send a copy of this wonderful book to every school, NHBS received 47 pallets of books directly from the printers, used seven pallets of specially designed cardboard boxes and 6039 metres of bubble wrap!
Eventually when all the books were packed the couriers took away 53 pallets of books from NHBS’ warehouse in Totnes, Devon over the course of a week.
The packing process took six people three and a half weeks to complete! You can watch the video below for a behind the scenes look at how this all happened.
Susan Young is a writer and photographer with a background in physics and engineering. She is the author of the fantastic CCTV for Wildlife Monitoring published earlier this year. This great handbook provides lots of practical information on the use of CCTV for survey and research.
Your book on CCTV for Wildlife Monitoring, published earlier this year, is packed full of practical information for the researcher or amateur naturalist interested in using CCTV to monitor wildlife. Could you explain a little bit about your professional background and how you came to write this book?
I have had a very varied career and have always tended to look for new ways to do things. After graduating, I worked using applied physics in the manufacture of aero engines, and later, after a Masters in Engineering Management, worked in a large electronics company. For the last 15 years I have been a writer and (mainly) wildlife photographer, and found my experience of great value with the more technical aspects of photography.
After using various photographic systems for recording wildlife, I came to believe that CCTV had many applications for both the amateur and professional naturalist. As I have always enjoyed doing something different, I spent the last few years researching CCTV systems for use with wildlife.
I wanted to test CCTV in more formal environments and thus I volunteered for Natural England and the Wildlife Trust. With Natural England I have been researching the use of an underwater system for studying fish in rural rivers, and have also developed a system for monitoring rock pool life. With the Woodland Trust I have developed a portable CCTV system for bat monitoring, which is being used for a research project at the moment, and which can greatly reduce the need for night emergence surveys.
With this research I became convinced that there were many applications where CCTV could be of great benefit, but that the lack of clear, relevant technical information was a barrier to wider use. The more I discovered about CCTV, the greater my enthusiasm for the subject, and the greater the number of applications that became apparent. For this reason I decided to write CCTV for Wildlife Monitoring with the aim of encouraging wider use of what I believe is a valuable tool.
Do you feel that there is a need to bridge the knowledge gap between manufacturers/engineers and the individuals using field equipment? As an extension of this, do you feel that it would improve the quality of research or survey data if people had a better understanding of the functions and limitations of their kit?
In meeting both professional and amateur naturalists, I have often heard it said that manufacturers/engineers do not understand their problems. Without that understanding, they are unable to advise on the areas of use. In addition, the biological sciences are not generally taught with an emphasis on technology, which can leave graduates unfamiliar with technical language. Companies such as NHBS and, hopefully, books like mine, can help to bridge what is a very large gap in communication.
I feel very strongly that there could be great steps forward in research and survey methods if people were more aware of the possibilities of their equipment, together with an understanding of the limitations. For the keen naturalist, there is also a great number of applications for filming for pleasure.
We have found trail cameras to be extremely popular both with amateur naturalists and researchers. How do you feel these compare with CCTV systems and in what types of situations would you recommend each of them?
This is a difficult question to answer briefly!
I have used trail cameras for many years and without doubt they are of great value for indicating the presence of wildlife, especially in remote areas, but their short filming time makes them less practical for monitoring. CCTV is much more flexible and responsive, and has the capability of giving higher quality images, especially at night. CCTV can be used with underwater cameras, and with cameras that fit into small spaces such as bird or mammal boxes.
One of the main advantages of a CCTV system is that it can be set up to record at certain times as well as being triggered by motion or event. The wide range of CCTV cameras means that variable focus lenses can be used, allowing one to zoom in to the subject, noise reduction can produce clean images and features such as ‘smart IR’ prevent over exposure of nearby objects, a problem with night images with trail cameras.
If mains power is available, the advantages of CCTV become more apparent. Recent technology means that HD cameras can be used, giving high quality HD videos, and images can be viewed live on a monitor. If the internet is also available, images can be viewed remotely by smartphone, tablet or PC.
HD analogue video (AHD or, more recently, HD-TVI) is an amazing step forward in CCTV, giving videos of great quality at a reasonable cost and without the complexity of more traditional HD methods which require some knowledge of computer networks.
You have a vast amount of experience in the field using CCTV and must have collected huge amounts of footage from this. How does it make you feel when you are reviewing your videos and come across something amazing? Do you have a single favourite video or image?
There is nothing to beat the excitement of coming across a video of something unexpected. The otter swimming underwater was caught by accident while filming fish and is very short, but still very exciting, and something I never really expected to get, although I was always hoping. I try to plan a CCTV session to reduce the number of ‘empty’ videos and to make sure that I review small numbers without letting them build up over days. That way, the excitement is always there.
Finally – if you could set up a CCTV system anywhere in the world, where would you choose?
I would choose the UK. UK wildlife is very elusive and offers a great challenge. I am an ‘otterholic’ and would love to set up cameras on the Shetland islands. I have photographed otters with a DSLR, but there is nothing to beat the excitement of filming otters in action.
Michael Scott is a nature writer and cruise ship speaker who has had an interest in botany since his undergraduate studies at Aberdeen University. His latest book, Mountain Flowers, is an extensive and engrossing survey of Britain’s montane flora. Michael expands on the story of Diapensia (see below) in the August 2016 issue of British Wildlife.
Tell us about the book and who might find it interesting.
I suppose it’s aimed mostly at people who already have some general interest in the wild flowers of Britain. Perhaps they already know something about the flora of lowland areas but don’t quite know where to begin seeking out the more elusive species that grow at higher altitudes in the British mountains. The book describes the key places to visit and some of the characteristic species at each site. It also describes the ecological requirements of each species, and I’d really hope that will encourage people to explore more widely in the mountains and hopefully make new discoveries there.
Many of the mountain areas of Britain are stunningly beautiful, and I would be thrilled if people who love mountains were also encouraged to read the book and discover more about these wonderful wild areas and about the colourful plants that grow beneath their feet as they hike the fells or ‘bag their Munros’. I’ve tried to select photos for the book that are as attractive and compelling as possible to inspire readers to explore and investigate – or just to act as a wonderful souvenir of holidays in Snowdonia, the Lake District, the Scottish Highlands or wherever.
I best sum up my objective for the book at the end of chapter one: “If I can persuade a few… hillwalkers to slow their relentless pace, to look around them as they climb, to venture off the beaten path and explore an interesting-looking crag or delve into the watery runnels that seep from the tops – in other words, to enjoy seeing a hill, rather than just conquering it – then this book will have been truly worthwhile.”
How did you first become interested in botany?
I grew up near Edinburgh Zoo and from an early age spent all my spare time in the zoo getting to know the animals. By the age of 8, I’d decided I wanted to be a zoologist when I grew up – which I thought meant going around the world looking at zoos! That enthusiasm never waned, and I went to Aberdeen University to study zoology. In first year we also had to study botany, and I found that new and fascinating. I knew that plants lay at the foot of all food chains, and therefore that plants were key to how the natural world worked, so I switched over to doing my degree in botany. I was lucky that the university had a field station at Bettyhill on the north coast of Scotland, and some of the first plants I got to know there were montane species growing at unusually low altitudes in the relative sub-arctic climate of the far north. Then, in Honours year, we had an amazing field trip to Obergurgl in the Alps, and I have been hooked on mountain flowers ever since.
You are now lucky enough to spend a lot of your time as a quest speaker on cruise ships around the world; how might you go about getting passengers interested in Britain’s mountain flowers?
It’s funny that you should ask that, because I’m just about to go off on a cruise to Nova Scotia in Canada, and on one of the four days when we sail back across the Atlantic to Liverpool I’m planning a talk called The Lure of Mountain Flowers. I think I’m going to start that with the story of a birdwatcher called Charles Tebbutt, who is best known for his book on the birds of (distinctly unmountainous!) Huntingdonshire. In July 1951, he was walking on a rugged hillside in Inverness-shire, when he spotted a plant at his feet that he didn’t recognise. He collected a few samples of the flowers and leaves, which he sent to various botanic gardens and he was promptly told, with some excitement, that he had discovered a rather handsome flower called Diapensia* which had never previously been recorded in Britain.
That may be 60 years ago now, but I think it shows that there might still be exciting discoveries to be made in the British mountains – and that you don’t need to be a professional botanist to make them! I’ll then go on to a series of beautiful scenic photographs, just to remind folk how beautiful our mountains are, then I’ll show some of our most attractive mountain plants to prove just how much they add to the allure of the hills. That will lead into the mystery stories behind these plants: I’ll speculate why Diapensia is still only known from that single, rather unremarkable hillside and what that might have to do with Norwegian commandos. I’ll tell the story of two attractive little plants that cling to survival in Snowdonia, and why a relative of the garden pinks is known from only two very different sites, one a crag in Lake District and the other a hillside of shattered rocks in Angus. There are plenty of ‘ripping yarns’ from mountain botany to interest cruise ship passengers – and I hope they will also inspire readers of my book.
(* Incidentally, I apologise to any keen botanists reading this who, like me, know many plants better by their scientific names. As in the book, I’m not quoting scientific names here because I don’t want to scare off readers who aren’t botanists – and those of us who are botanists probably have plenty of books in which we can check the scientific names if we need them).
What distinguishes a mountain flower and how many such species occur in Britain?
That’s a really good question. Many of them are species which also grow in the Alpine regions of central Europe or in the Arctic regions of the far north, so they are categorised broadly as ‘arctic-alpines’ – a term that will be familiar to most gardeners. But Britain lies in a special position off the west coast of Europe and its climate is tempered by winds that come off the Atlantic. As a result, many alpine species grow here at dramatically lower altitudes than where they occur in the Alps, and some arctic species also grow here, far south of their normal latitudes. Several species meet on the mountain cliffs of the Lake District or the southern Highlands of Scotland that grow together nowhere else in the world (which makes these especially important conservation sites in an international perspective). I also list in the book several species that grow in Britain at their northernmost or their southernmost sites in the world.
So, although I could define a mountain plant as one that grows typically above, say, 1,500 feet, that doesn’t always work in Britain because many of these come down almost to sea-level on the wind-battered north coast of Scotland or on the Western and Northern Isles – and that’s what makes British mountain botanising so intriguing. In fact, I almost reverse the argument in the book. I have selected 152 species that I regard as typically montane, then, for the purposes of the book, I define mountains as places where these plants grow – and these range from unexpected places like The Lizard in Cornwall, right up to the island of Unst in Shetland.
Tell us more about the unique conditions in the UK and their effect on mountain flower distribution.
The important thing to recognise is that many of our montane species have been clinging to survival on remote mountain ledges since just after the end of the last Ice Age. They survive there because of the chance juxtaposition of the right kind of rock and soil and a local microclimate that mimics the conditions to which they are adapted elsewhere in the high mountains of Europe or the high Arctic. It is vitally important that we try to understand why they survive there and continue to monitor their populations, because these are the plants that will give us the first warning of changes that are likely to happen on a much bigger scale in the Alps and the Arctic because of climate change. They are vital “miners’ canaries” for what lies ahead – plus I think Britain would be infinitely the poorer were we to lose them from our hills.
How have 21st century developments in botanical research affected our understanding of mountain flower ecology?
Hmm… In the strictest sense of botanical research, the latest genetic studies have sometimes made life a bit more difficult, especially for ageing botanists like me! It has changed our understanding of the relationships between species which in turn has led to a lot of changes in scientific names and how species fit into our concepts of plant families. It has also shown that one or two of what we thought were good mountain species are actually just variants of much commoner species, highly adapted to the mountain environment.
What has increased hugely over the 60 years since the last major account of British mountain flowers was published is our knowledge of the distribution of our mountain flowers, thanks to the hard work of hundreds of botanists in recording schemes masterminded by the Botanical Society of Britain & Ireland (BSBI). The BSBI published increasingly comprehensive atlases showing the distribution of our native plants in 1962 and in 2002, and recorders are now hard at work gathering data for the next Atlas 2020 project, due to be completed in three years’ time, while, all round the country, enthusiastic botanists have compiled and published detailed accounts of the plants of their local counties or areas. I was given privileged access to the BSBI’s online databases in compiling the information in my book, and I am hugely grateful for that.
What I now want is for readers to prove me wrong! From the BSBI databases, I have tried to note the northernmost and the southernmost sites from where the key montane species have been recorded, and the highest and lowest altitudes at which they have been found, but I am sure keen readers could find new records beyond these extremes – and report them, I hope, to their local botanical recorder. I have reported on sites from which certain species appear to have died out, and I would be thrilled if that encouraged readers to go out and re-find the plants there.
What is the biggest conservation threat to mountain flowers in the UK?
I imagine most informed readers of the NHBS newsletter would expect me to say climate change was the biggest threat to mountain plants, and, in the long term, there is no doubt that climate change is a huge threat. But, as I have tried to show in the book, the impact of climate change on the mountain environment in the short to middle term is difficult to predict with any certainty and may not immediately be as disastrous as we fear.
What is beyond doubt is that, if we are to give montane plants any chance of adapting to the changes ahead, we need to get much better at managing our hills and mountains. Overgrazing by red deer is a huge problem across most of Scotland. The regular burning of moorland areas that are managed for the sport shooting of red grouse or to produce a ‘spring bite’ for sheep tends to encourage a few resilient species at the expense of many other, more delicate plants. Yet some mountain habitats also benefit from restricted amounts of grazing, and if continuing financial challenges lead to further declines of extensive sheep farming in the uplands that could become a big problem too. The challenge lies in getting the right balance between these conflicting priorities – and I’m afraid the decision by the people of England and Wales to leave the European Union (the EU has been a huge help in establishing conservation priorities in Britain) is not going to make that any easier.
Tell us about some specific species you find particularly interesting and that feature in the book.
In the book I have selected 18 species, most of which are rarities, whose distribution and survival particularly intrigues me. I call them “Three-star Mountain Enigmas” for reasons I explain in the book and I give an extended account of each of them. For some of these species, I hope to shed insight, based on the scientific researches of dedicated mountain botanists; for others, I can only pose questions, in the hope of inspiring someone to find an answer. And there are plenty of puzzles in our mountains. Why, for example, is Alpine Rockcress found only in a single corrie in Scotland, when it grows almost as a weed in disturbed ground in the Alps and Arctic? Why (and how) is Iceland Purslane dispersed all the way from Iceland to Tierra del Fuego, yet in Britain it only grows on gravelly slopes on the Isles of Skye and Mull?
In the book, I suggest that Alpine Sowthistle is restricted to tiny populations on just four remote cliffs in the eastern Highlands of Scotland because humans have almost completely destroyed the mountain woods in which it once grew (and where it still flourishes in the Alps and Scandinavia), and I show how the 2001 outbreak of Foot-and-mouth Disease revealed how Marsh Saxifrage and Alpine Foxtail grass are actually much commoner than we ever realised.
For someone interested in a bit of amateur research, where are some of the best spots for finding mountain flowers?
I’d always say that the best place to start is the montane site that is nearest to home, whether that’s the Brecon Beacons, the Peak District, the Pentland Hills or wherever – they’re all covered in the book. Then you can make regular visits through the spring and summer to find each of the local species in full flower and follow them through the season to catch them in seed too (there are some species which you can only identify with certainty if you can find their fruits as well as their flowers) – although I should add that, by the time you read this, it is probably a bit late in the year already for mountain plants, so buy the book and start planning for next year!
Once you have got to know the commoner montane species for your local patch, you can perhaps plan a holiday further afield to one of the real mountain hotspots, like Snowdonia or Upper Teesdale, the Breadalbane hills of Perthshire or the Cairngorm Mountains of Inverness-shire. One spot that I particularly recommend in the book is the area around the Glenshee Ski Area, south of Braemar in Aberdeenshire. The A93 road from Blairgowrie to Braemar rises here to 670m (around 2,200 feet), so montane species grow right beside the car park, but the area is already so well-used by skiers that you needn’t worry too much about damaging the vegetation – and there are some really special plants for plant explorers to find.
It is currently the school summer holiday period – any tips for getting kids interested in botany?
Another great question. Kids like action, and it’s the perfect time of year to show plants in action. Find the different kinds of fruits that plants produce and see how they are dispersed. Find the winged fruits (called samaras) of a sycamore tree or the ‘keys’ of an ash tree and work out how they spread. Who can get their fruit to travel furthest? Find some dandelion ‘clocks’. Don’t just see how may blows it takes to remove all the seeds from the ‘clock’; instead try to follow one of the seeds on its little parachute and find out how far it travels. If you can find a patch of Rosebay Willowherb, investigate how it spreads its seeds. If a riverside near you has been invaded by Himalayan Balsam (aka Policeman’s Helmet); see if you can work out how its explosive fruits have made it a successful ‘Alien Invader’ (in this case from India, not from Outer Space). How do the wild relatives of garden peas and strawberries spread – and what about potatoes? If you want to get really yucky, you might want to ask kids why they think tomato plants sometimes start growing beside sewage treatment plants!
If you have a boggy area nearby, see if you can find Common Butterwort growing there and investigate how its sticky leaves trap little insects which the plant then dissolves and absorbs to get the nutrients it needs to grow. Even better, see if you can find Common Sundew whose leaves are covered in red hairs which curve over to trap little insects caught by the sticky surface of the leaves. Then go online to discover how Venus Flytraps, Pitcher Plants and other insectivorous plants trap their prey – there are some great websites aimed at youngsters about these plants.
The BioEcoSS TubeTrap is a new product for ecologists and researchers conducting mammal surveys. The innovative design is the work of data consultant Simon Poulton, who told us more about his company and his revolutionary new small mammal trap.
Tell us a little about your organisation and how you got started. BioEcoSS Ltd is a consultancy specialising in all aspects of ecological data handling and analysis. I became a consultant after taking voluntary severance from ADAS, which was the scientific and advisory arm of the old MAFF – precursor to DEFRA, for the youngsters among you. I had worked for them for 14 years, developing from basic wildlife advice through to coordinating the national monitoring of Environmentally Sensitive Areas and other agri-environment schemes. Change was in the air, with ADAS becoming a “Next-Steps Agency”. So, I decided to go it alone, allowing me to concentrate more on the practical side of database design and statistical analysis – rather than managing teams and editing their reports. It also allowed me to select my clients to focus more on the taxa that I was interested in – primarily mammals and birds.
Why the name? Well, when I set up as a consultant I had a very loyal spaniel call Bess. Struggling to come up with a descriptive name that had “ecology” and “statistics” in it, a mischievous friend took one look at the adoring dog at my feet, and suggested BESS. So, I became Biological & Ecological Statistical Services! Bit of a stretch – but it caught on. Then when I converted to a limited company five years later, I thought I’d better have something a bit more respectable – so BioEcoSS Ltd was born.
Over the last 18 years, I’ve had a good number of clients, including universities, NGOs such as the Mammal Society, Vincent Wildlife Trust & BTO and government departments such as Natural England, CCW and JNCC. My work has generally fallen into two types:
a) ecological database design, and
b) statistical analysis of existing datasets.
However, in all my projects, I’ve tried to emphasise the importance of incorporating these aspects at the project planning stage – very often they’re not! So, it’s not unusual for clients to turn up with a dataset that’s been stored in a spreadsheet, riven with errors, and with a survey design that just doesn’t give them the power they need to detect change or spatial variation. I do what I can, but it would be so much better if these aspects were considered more carefully at the outset as part of an integrated design – sorry, that’s a bit of a lecture!
What was the original inspiration behind the TubeTrap?
About six or seven years ago, when I was on the council of the Mammal Society, we were discussing the setting up of a national small mammal monitoring scheme. The then chair, Dr Johnny Birks (very well-known to all mammalogists), lent back in his chair and sighed “It’s such a shame we don’t have a good trap at a reasonable price!”. We all agreed that we would have to focus on non-invasive methods for a large-scale, mass-participation survey – which is not a bad thing anyway – but there was still a need for trapping to provide high quality data.
On the train home I started thinking about this idea. Database design is a very creative and practical process –understanding the requirements of the user and combining these with practical and intuitive solutions. And I felt I was fairly practical – good with wood and I seem to be forever re-plumbing my house! As the son of an engineer, I thought I might be able to come up with a good design for a mouse trap. After all, I had been using the trusty Longworth and even some old Shermans for over 25 years, so I knew their faults and limitations.
So over the next 18 months I set out to build a prototype. I was certain that injection moulding was the answer to producing large numbers of cheap traps and I was very lucky to get some financial help from the, now sadly defunct, Manufacturing Advisory Service. I also fell on my feet by finding two incredibly helpful and innovative small companies in the West Midlands; an injection tool-making company (BFT Engineering) and an injection moulding company (BTF Polymers). (The names are purely coincidental – they’re not related in any way – but they continue to cause me total confusion!) These guys were enormously helpful in designing the tools and producing prototypes for testing. So – TubeTraps are entirely British made!
How does the TubeTrap compare to other small mammal traps on the market?
Well! What do you expect me to say – pretty good I reckon! Seriously –I think there are three primary aspects to the efficacy of a small mammal trap:
1) How well do they catch?
2) How humane are they?
3) How practical are they to use?
In the UK the main competitor is, obviously, the Longworth. This has remained virtually unchanged over the last 50 years so, in an evolutionary sense, it must be pretty well adapted to what it does. I’ve carried out some comparative trials (as have six or seven users) which shows that TubeTraps catch just as well as Longworths. As the number of trials increases, there’s even some evidence that they are better at catching very small animals such as pygmy shrews and harvest mice. I’m hoping that two students from UEA will be trialling the traps this autumn to provide enough data to show this is statistically significant. I’ve not compared them directly with Shermans or Trip Traps, but people have told me, anecdotally, that TubeTraps have a higher capture-rate.
Part of the design was to make a trap that was as humane as possible. Obviously, the correct setting and use of traps goes a long way to ensure the survival of captured animals – in particular, live invertebrate food for shrews is essential, as is regular checking. But I wanted the TubeTrap to help prevent exposure of animals, so the use of plastic and the double-walled nest-box provide much better insulation. I’ve also had a bit of a theory about shrew deaths. A very light animal (say a pygmy or juvenile common shrew) enters a trap without tripping it, scoffs all the food and then leaves. Along comes an adult shrew, trips the door and finds a trap with no food. Result – starvation. So I think the very sensitive and stable mechanism of TubeTraps will help prevent this situation.
The practicality aspects of the design were very important, especially setting the trap and cleaning. The nestbox and tunnel parts of the trap snap together very intuitively and are virtually impossible to pop open accidentally – unlike a poorly set Longworth. The smooth, cylindrical profile of the trap makes it very easy to push into dense vegetation and remove for emptying. Again – in the past, I’ve popped open Longworths when pulling them out of hedgerows as the corners of the nest box or the hook of the pin hinge catches on a bramble. The TubeTrap’s white doors are very easy to see, even in poor light, so it’s much easier to check when they are closed. So too with the pre-bait lock – it has a very visual appearance, so it’s much more difficult to leave a trap locked open by mistake. The round profile of the nestbox and the flat base of the tunnel with no side-walls make them very easy to clean. Finally – and possibly most importantly, all parts of the trap snap together, so it’s very easy to replace any damaged parts. I always carry a few spare triggers (which can get chewed) and the elastic springs for replacement in the field.
Development of the TubeTrap is continuous and I’m pleased to say that NHBS is stocking the new Mark II version. This has a more stable trip mechanism, which is counter-balanced, making it much more difficult to accidentally trip when knocked or jolted. This also makes it easier to set TubeTraps in awkward places or above-ground attached to branches or poles. There was an issue in the original design with surface-tension from rainwater holding the doors open, but a number of modifications in the new Mark II trap have addressed this.
How and where have TubeTraps been used and what is the most interesting species you have caught?
TubeTraps have been used by a number of universities, county mammal groups and wildlife trusts. As far as I know, they are being used for mammal research, survey and monitoring. Also, I know that the trusts have used them for training and open-days, so they’re proving versatile.
As you may have gathered from some of the time periods I mentioned earlier, I’m getting a bit long-in-the-tooth! But, a few years ago I finally started the PhD (at UEA) that I’d never got around to doing. I’m looking at altitudinal variation in small mammal communities in the central Himalayas of Nepal – using 120 of my traps of course! I’ve done three seasons’ fieldwork and caught 795 animals at altitudes from 1300m to 4200m. The traps have performed very well and have been catching hundreds of tiny shrews, as well as some pretty hefty rats weighing over 100g. The CarryCases have also been fantastic, not just for carrying the traps, but as dissection and dinner tables! There’s no doubt in my mind that the best animal I have caught is a tiny shrew called Episoriculus leucops – only 5g in weight, but with the longest tail you’ve ever seen (pic above).
What do you consider the most important achievement of your organisation in recent years?
That’s a tricky question! I think just because of the size of the project and its subject – the Environmental Monitoring Database for Natural England. I’ve worked on this for over ten years, bringing together into a single database all the agri-environment monitoring data carried out since 1987. There are over 4.25 million data items in this database, which makes it a unique resource. But how can I not mention the work I’ve done with excellent conservation organisations such as the Mammal Society (scoping and setting up the national small mammal monitoring scheme with Phoebe Carter and Johnny Birks) or the Vincent Wildlife Trust (analysing their fantastic dataset on batbox usage collected by the tireless Colin Morris and his colleagues).
But, I also hope I’ve made a real contribution in Nepal, mostly by giving young ecologists hands-on experience of fieldwork, statistical advice and training that they wouldn’t otherwise have access to. I should say that this has been a two-way process and I’ve had fantastic support from them (Hari Basnet, Sagar Dahal, Hem Kathuwal and others). I would also like to mention my friends and colleagues, Laxman Poudyal, Sujan Maharjan, Hem Sagar Baral, Sharad Singh and Dibesh Karmacharya – who have all helped in this reciprocal process. And – most importantly – the porters, whose superhuman efforts at carrying traps, collecting water and wood, cooking amazing food and generally remaining completely cheerful made this work possible.
What is your most memorable wildlife encounter?
Another tricky one! I’ve had a long-lasting love affair with India and Nepal, so I should say the tigers I saw in Kanha and Ranthambore National Parks, or Indian one-horned rhinos in Kazirangha or the fantastic nilgai in Sariska. But, actually, the most thrilling was probably five years ago at 3500m in Nepal when my colleagues and I came across a very (I mean VERY) fresh set of prints of himalayan black bear only a few meters from our camp-site. That certainly caused a stir amongst the porters! Then again – the most sublime moment was probably during that expedition, being out just before dawn, when the koklass pheasants started calling. Their harsh cries carry for hundreds of metres through the gloom – the Nepalis’ literal interpretation is “How are you, Uncle?”. It’s a spine-tingling memory just thinking about it.
Any new inventions in the pipeline?
I might have! Actually, a client from Ireland recently asked if I could produce traps with shrew holes. It had been on my mind for a while, so I made 30 doors with shrew holes for her. She’s trialling them now and if they work well, I’ll make them generally available. The benefit of putting the holes in the doors is that you can easily snap these out and replace them with standard doors if you don’t want the shrew holes.
I do have another idea, but I’m keeping my cards close to my chest at the moment. Suffice it to say – if it works it could revolutionise small mammal trapping – I’m saying no more!
Tell us a little about your organisation and how you got started.
Third Wheel Ringing Supplies has been trading for about two years and comprises myself and my wife, Mary. We make a small range of equipment for ringers, specialising in traps and particularly trying to fill gaps in the market. Traditionally much of this sort of equipment has either been knocked together by ringers themselves or imported (expensively) from Europe or North America.
Our range is still very small, but it is gradually expanding as we develop more products. Product development is very slow however as, with bird safety being so important, any new product has to be extensively tested before it can be offered for sale. Nevertheless a slightly expanded product range should be launched in the coming months. Our manufacturing ethos is based on quality; never knowingly making sub-standard equipment in the quest for cheaper production costs. Hence our products are not the cheapest available, but they might be the best.
The business started when I took voluntary redundancy from my job. Having worked for (among others) The Wildlife Trusts, RSPB and Local Authorities as a nature reserves manager for 30 years, I was ready for a change. I’ve always liked making things and have a good grounding in engineering which, together with my interest in bird ringing, led onto me making various bits of ringing equipment for my own use and thence onto a small business, making equipment for other ringers.
Why Third Wheel? Well, we had to call it something and, having a slight obsession with classic motorcycles, particularly those with sidecars, the name seemed to fit us as a family.
What challenges do you face as an organisation working in the ecology sector?
One of our biggest challenges has been to persuade ringers not to rely so heavily on mist nets all the time. Although mist nets are very effective for many species and situations, they still have their limitations and traps can often be just as effective or, for some species, the only method of capture. Increasing numbers of ringers are starting to appreciate the value of different trap designs and, as traps form the mainstay of our business, we see this as a good thing!
What do you consider the most important achievement of your organisation in recent years?
On a purely personal level, Third Wheel’s most important achievement has been that, after only two years of trading, it seems to be working as a business. Although I have a passion for what I do, it still has to pay the bills and, for the time being at least, it is doing just that.
It has also been particularly gratifying to have our equipment used to great effect in a number of research projects worldwide. In addition to various projects in Europe, Third Wheel traps are used for chickadee research in Florida, grey jay research in Alaska and snow bunting research in the Canadian Arctic.
Nearer home, highlights have been a customer who caught a dunnock within 7 minutes of the postman delivering one of our traps and another who, on taking delivery of a new prototype, caught 55 linnets on the first morning.
What is your most memorable wildlife encounter?
Having been pursuing wildlife for nearly my whole life, I’ve been lucky enough to have many memorable wildlife encounters, which makes choosing a favourite rather tricky.
I’ve visited Svalbard (what we used to call Spitsbergen) in the High Arctic many times, as a leader of study tours. Here the memorable wildlife moments come thick and fast with polar bear, Arctic fox, beluga whale and countless breeding auks, wildfowl and waders against a stunning scenic backdrop.
On the bird ringing side of things, my best and most memorable ringing sessions have been catches of wigeon, teal and other wintering wildfowl as part of a cannon netting team. Wigeon are amazing little ducks and to ring one in Devon which probably breeds in central Russia is a real privilege.
As part of their Heritage Ability project, Living Options Devon recently hosted the UK’s first ever Deaf-led bat walk at the Love Parks event, in Cockington Park, Devon.
NHBS are delighted to have been able to loan them an Echo Meter Touch bat detector from Wildlife Acoustics, which allowed the attendants to view live sonograms on an iPad – whilst receiving further information in British Sign Language from the guide, Alasdair Grant.
This fantastic event was part of a whole day of activities helping to make heritage sites more accessible for disabled and Deaf people.
Alasdair, Deaf Alumni Programme Manager for Deaf Unity, who is working towards his bat license, led an inspiring bat walk which one participant said was “a memorable and unique experience”. The walk included watching soprano pipistrelles and lesser horseshoe bats exiting their roosts in outbuildings in Cockington Court, and common pipstrelles, serotine and noctule bats feeding in the park and lakes area.
The walk provided a unique opportunity for Deaf people to see and learn more about the lifestyle of our British bats and how to identify different species using bat detectors with visual sonograms rather than by sound. The Echo Meter Touch connects to an iPad to provide an excellent and very accessible visual display of bat calls in real time.
Living Options and Deaf Unity very much hope to run further bat walks in the future and would be delighted to advise other organisations and bat groups on how to lead bat walks for Deaf people.
The Heritage Ability Project supports heritage sites in South West England to improve accessibility for disabled people. Funded by the Heritage Lottery Fund, the project is currently piloting different approaches with partner sites including museums, country parks, nature reserves and historic houses.
Best bat detectors for bat walks
Echo Meter Touch
This tiny ultrasound module connects directly to your Apple device and lets you listen to bat calls in real time as well as viewing a live sonogram on your screen. Ideal for bat walk leaders, the Echo Meter Touch provides you with plenty of real time information to share with your group, as well as letting you record and classify calls so you can provide a later update of all species heard during the walk.
The Batscanner is one of the simplest bat detectors on the market – simply turn it on and listen. The device will automatically tune to the frequency of the bat call nearby and will display this frequency on the LCD screen whilst playing the sound back at an audible level.
The SSF Bat2 cleverly scans all frequencies simultaneously and will jump to the peak (loudest) frequency at the touch of a button. Pre-programme up to four fixed frequencies and view a small spectrogram of the received call. Ideal for beginner or seasoned bat walkers.
Magenta Bat 4 and 5
The Magenta Bat 4 and Magenta Bat 5 are our most popular detectors for beginners. Affordable to buy and simple to use, they convert the call produced by the bat into a sound which is easily heard through the speaker. Simply tune to the required frequency using the large dial on the front of the unit. The Bat 5 also has a digital display which makes tuning the detector even easier.
Your book is proving to be a huge success – what prompted you to write it, and who is your target audience?
It mostly came about from the grass courses I’ve run for the last seven years, during which I built up a huge body of observational evidence on grasses, from chatting to people and just spending a lot of time looking at them. Teaching plants is fantastic as it really makes you be concise about why things are what they are, plus you get to see what people muddle up; things you might never think yourself.
In addition I felt there was a niche for an affordable, portable, and easy to use book. It definitely won’t suit everyone, but I hope that people who might have been put off by some of the more weighty tomes might find this a good way in (which certainly applies to me). It won’t teach you every grass, but hopefully it will make people feel much more confident about the ones you tend to encounter regularly.
How did you become interested in grasses?
During my early years of being a botanist I was terrified of grasses and it took me a long while to get a handle on them. This came about from spending time with other friendly botanists and gleaning as much as I could from them. Once I had got better at them (and I’m still a long way from mastering them) I was really keen to share this knowledge with other people. I did my first grasses course at the Kingcombe Centre 7 years ago, which I was absolutely terrified about running, but it went OK, and it all moved from there. I now run about 18 grasses courses a year, which I absolutely love doing, and all the proceeds from these go into our species conservation programme, meaning a single day’s training can fund a species programme for a year.
What defines the graminoids, and how can the three groups – grasses, rushes, and sedges – be distinguished?
It’s a difficult term, graminoids! I’m very guilty of calling them grasses, which of course only some of them (the Poaceae) are. I also tend to commit the grave sin of talking about wildflowers and grasses (especially when describing courses) when of course grasses are in fact flowers. Their key characters are that they are all monocots, and exclusively wind pollinated.
Telling them apart can be relatively easy, the rushes tend to have waxy round stems, the sedges are tussocky with separate female and male inflorescences, and the grasses are, well… grassy looking? But there are so many exceptions to this! Just today I was running a course where someone muddled up Slender Rush with Remote Sedge, and I realised that these two look almost identical from a distance!
What is the importance of the graminoids in the ecosystem at large?
Graminoids are exceptionally useful as indicator species, with many of them showing incredible affinity to certain soil types, nutrient levels and pH. If you walk into a field and see a shiny green swath of Perennial Ryegrass you know you’re unlikely to be finding overwhelming levels of biodiversity. Go into another field and find a clump of Meadow Oatgrass and you know you’re in for a long haul of finding other species.
As it says on the Species Recovery Trust website, over the past 200 years, over 400 species have been lost from England alone. Do you think enough is being done to halt biodiversity loss in the UK?
Tricky question! We have an incredibly large and diverse conservation sector in the UK, full of talented and passionate individuals devoting their lives to saving the planet. And yet we are still losing species at an alarming rate. When I was born, just over 40 years ago, the world had twice as many species as it does now, so this is not a historical problem we can blame on previous generations, this is the here and now of how humans are choosing to live our lives and harm our planet.
These are clearly difficult times financially, and clearly every sector is feeling the pain of budget cuts, however it is upsetting to see the way biodiversity has almost dropped off current political agendas (the environment was barely mentioned at all in the referendum debates) so I do worry that people, and governments, are just not doing enough. It is now fairly widely accepted that we are living through (and causing) a sixth mass global extinction event, which should be the biggest story and policy issue anyone is talking about, and yet species conservation still seems to be a niche market!
What does it take to re-establish a species like Starved Wood-sedge, which is one of the Trust’s Species Recovery Projects?
Starved Wood-sedge (SWS) has two native sites in the UK, and we’re working hard at both of these over a long time period to steadily improve the conditions, bringing more light in through coppicing and canopy reduction, and trying to encourage seedling establishment through ground scarification. SWS has an interesting bit of trivia in that it has the largest utricles (seeds) of any native sedges which should make it very easy to grow, but recently we started to think these large seeds may be their downfall as they are so susceptible to vole and mouse predation – but it’s hard to know for sure. We have established and continue to closely work on the two re-introduction sites, where we used plants grown up by Kew Gardens to establish new populations, and we are keen to establish one more in the next decade in a more traditionally managed wood to look at how the species would fare in active coppice rotation.
If you could put one policy change in place today to enhance species conservation what would it be?
I’m not sure, my current rather grassroots view is I’m not sure if conservation isn’t dying a death by policy. A few years back I spent the best part of two years of my life working on Biodiversity Opportunity Areas, only to see these being replaced by IBDAs (which I’ve now forgotten what it stands for) only to see these superseded by NIAs. I then had somewhat of a personal crisis that in all that time, even though I’d been instrumental in producing some very interesting maps of core area and buffer zones and opportunity areas, I’d done absolutely nothing to help species on the ground. I think it was during this same time that Deptford Pink went extinct in Somerset and Dorset too, which I still feel pretty bad about.
The problem with policies, and ministers, and successive governments is that they never last for that long. While not disputing that our current democracy is a wonderful thing, and obviously I feel lucky to live in a country where we can all vote and potentially change things we like, if you superimpose governments and policies on top of the Anthropocene (the current geological age where humans have gained the ability to start fundamentally changing the planet, both in terms of biodiversity and climate) then the two simply don’t match up in terms of the timescales we need to be operating on to bring a meaningful change to biodiversity loss. And it goes without saying that when government budget cuts occur it will always be the environment sector that will suffer, and this obviously has a terrible net effect on projects that are up and running and are suddenly suspended.
Without wanting to sound too ‘big society’ I think the meaningful changes we are seeing are from individuals, either making a big difference in their jobs in the environment sector, or simple volunteering, spending a few days a year clearing bramble from around a rare species, counting butterflies on a transect, monitoring their local bat populations. For me, that is where change is happening, not in government policy units.
How would you encourage a young nature lover or student to take an interest in the subject of grasses?
I’m lucky to have two young children to try this out on, and I must say they are now budding graminologists. I think the starting point is everyone likes knowing what things are and naming them, whether it’s music, works of art, types of lorry. We are on the whole naturally inquisitive beings, so I just tend to show people things and encourage them to go off and find more like them. Add to that some stripy pyjama bottoms (Yorkshire Fog), Batman’s Helmet (Timothy), Floating Sugarpuffs (Quaking Grass) and Spiky Porcupines (Meadow Oatgrass) and the whole thing becomes pretty fun! Incidentally there are equivalent adult versions of these too, which are unmentionable here…
What is the most surprising, odd, or unexpected fact you can share about grasses?
Grasses have a profound link with humanity. 4 million years ago the spread of grasses in the savannas of East Africa is now believed to be the main driver in our primate ancestors coming down from the trees and developing a bipedal habit to move between patches of shrinking forest while keeping a watch out for predators. 40,000 years ago we saw the birth of agriculture with the development of early crops, the decline of hunter gatherer lifestyles and the start of the society we live in today (gluten intolerance sufferers probably think this is where it all started to go wrong). And all because we learnt to collect seed from promising looking grasses, and start planting in quantities we could harvest.
Tell us more about the plant identification courses. What are these all about and how people can get involved?
When we set up The Species Recovery Trust we knew that funding projects over a long term basis (all our work plans are 50 years long) was going to be a challenge, so we set about seeking ways to bring in modest sums of unrestricted funding over that period of time, for which running training courses was an obvious contender. This was combined with my passion for teaching plants, and then finding other people who shared this view. We’ve now been able to build up a team of some of the best tutors in the country, who combine their expert knowledge with running courses that are extremely fun and really help people get to grips with a range of subjects.
By automating the booking process (which works most of the time) we can also keep our prices extremely competitive, as well as offer discounted places for students and unemployed people who are desperate to get into the sector. On alternate years we offer one ‘golden ticket’ which enables one winner to attend 10 training courses for free, which will give people a huge helping hand in their conservation careers.
All the information on the courses can be found on the training courses page of The Species Recovery Trust website.
Can you tell us about any interesting projects you are involved with at the moment?
We have a great project running on Spiked Rampion at the moment, and after 6 years we now have the highest number of plants ever recorded, all due to a fantastic steering group of the good and great from Kew, Forestry Commission, Sussex Wildlife Trust, and East Sussex County Council, along with some very committed local volunteers. It’s been a lot of work but proved a great example of many organisations joining up with a single achievable aim of saving a really rather special plant from extinction.
This summer is going to see a network of data loggers placed around the New Forest as part of a project to re-discover the New Forest Cicada, that we’re working on with Buglife and Southampton University. There are real concerns about whether this species is already extinct, but as it spends most of its life underground and only emerges and sings for a short period it is a good contender for the UK’s most elusive species.
