The NHBS Guide to Kick Sampling

Freshwater invertebrates Credit: Katharine Clayton

The presence or absence of freshwater invertebrates such as caddisfly (Trichoptera) and mayfly (Ephemeroptera) larvae, dragonfly and damselfly nymphs (Odonata) and planaria (Tricladida) can be used to provide an indicator of the health status of waterways.

Kick sampling

Kick sampling is a useful method for collecting these and other invertebrates from shallow waters and one of the key techniques used in monitoring freshwater invertebrates in rivers. The technique involves agitating the stones or sediment of a river or stream by foot and catching the sample in a sturdy hand net that is held downstream. Stones and logs can also be washed off carefully into the net and samples are usually taken both from faster flowing riffles and still areas of the river. The sample is then rinsed out of the net into a tray full of water for sorting and identification. Kick sampling is primarily a qualitative technique, to look at species diversity or presence/absence, but quantitative measures can be taken if a quadrat or transect is used on the floor of the water body to limit the sampling area and sampling time is controlled.

Scientist sorting biological net samples at a wetland

NHBS manufactures a range of hand nets that are the industry standard for kick sampling and are widely used by environment agencies and ecological professionals. Our Professional Hand Nets conform to the Environment Agency standards and we are the official Riverfly Partnership supplier. The Riverfly Partnership is a network of organisations bringing together anglers, conservationists, entomologists and relevant water authorities whose aim is to protect and monitor the water quality of our rivers.

The NHBS net range also includes smaller nets designed for students of all ages and a wide range of accessories and books to help with sample sorting and identification. Our hand nets are manufactured with a diverse range of net bags and handles to meet a wide variety of surveying purposes. We can also design and manufacture bespoke net designs in our workshop in Devon, so please do get in touch if you have special requirements.

Professional Hand Nets

The NHBS Professional Hand Net has been used for over 30 years in Environment Agency monitoring and was purpose designed to be lightweight, strong and long-lasting, with individual nets often still being used after ten years. Key features of the Professional Hand Nets include:

  1. The net bag is protected by the outer frame to minimise abrasion when kick sampling on stony surfaces.
  2. A range of mesh sizes are available, making it the ideal net for aquatic surveying of all macro- and microinvertebrates in shallow water. The bag mesh is either made from 1mm or 2mm woven polyester or precision welded nylon mesh (53µm to 500µm) and manufactured to international standards so that the mesh will stay the same shape and size, even under stress.
  3. The inner brass frame securely holds the bag away from the stony substrate and also allows the bag to be removed for sterilisation between sites.
  4. The comfortable handle is available in either a lightweight FSC wooden or aluminium version and both will float in water.  Two-part and three-part sectional wooden handles are also available, which can be unscrewed for transport or extended with extra sections.

Student Hand Nets

The Professional Hand Net is also available in a smaller Student version that is 200mm in width. This is designed to the same high quality as the larger Professional net but is ideal for educational use. The Student Hand Net is available with either a FSC wooden or aluminium handle and with net bag mesh sizes ranging from 250µm to 2mm, in standard 280mm or 380mm depth. We can design and manufacture bespoke nets so please do contact us with any requirements.

Lightweight Eco-Nets

The Lightweight Eco-Net has a strong aluminium frame that will withstand regular use both for kick sampling and pond dipping. Net heads are 160mm in width and 1mm and 2mm mesh bags are available to fit this frame. Bags attach to the head using industrial hook and loop strapping, making them easy to remove for replacement or sterilisation.

Riverfly Partnership Approved Kit

The Anglers’ Riverfly Monitoring Initiative (ARMI) is coordinated by the Riverfly Partnership and involves anglers and conservation volunteers from more than 100 partner organisations carrying out regular freshwater invertebrate surveys to check for severe changes in water quality. The Riverfly Partnership Approved Kit has been designed in conjunction with the Riverfly Partnership and contains everything the volunteers need to carry out these vital surveys: Professional Hand Net, bucket, sample trays, pipettes, freshwater invertebrate ID guide, spoon, brush and magnifiers.

Banner Net

The Banner Net is a rectangular net measuring 90 x 100cm that is supported on each side by a 120cm wooden pole. The bottom edge of the net is reinforced with a removable, flexible rubber rod. Two hook and loop tabs keep the net rolled neatly when not in use. Available with 500mm mesh, which is ideal for kick sampling of benthic macroinvertebrates.

Author Interview: Kate Bradbury

 

If you want to attract more bees, birds, frogs and hedgehogs into your garden, look no further than Wildlife Gardening for Everyone and Everything. Award-winning author and journalist, Kate Bradbury offers tips on feeding your neighbourhood wildlife and explains how you can create the perfect habitats for species you’d like to welcome into your garden.

Kate kindly took some time out to answer our wildlife gardening questions, to help us get our gardens wildlife-friendly for summer!

(c) Sarah Cuttle

Can you tell us a little about your background and how you got interested in the natural world?

I grew up in a house with half an acre of garden out the back. I spend my early years out there, grubbing around in the soil looking for worms, watching the birds. I started gardening from a very young age and the natural world has always been a part of that, for me.

What interests you about gardening for wildlife?

I’ve always been a softie and I’ve always championed the underdog. I love garden wildlife but I’m also passionate about looking after it, and can see the potential our gardens have for saving so many species. Wildlife gardening is all about the power of the individual. There are so many things going on in the world we might feel powerless to change, but simply by planting flowers and caterpillar foodplants we can make a difference for local wildlife species.

I get particularly excited if I find a slow worm in the garden. What animal gives you the most pleasure if you see it visiting, or making a home in your garden?

I couldn’t pick just one! In my new garden I’m desperate to see a toad. They’re so rarely seen these days – I’d be honoured if they found their way to my garden. I’m lucky enough to have hedgehogs so I love seeing them. And a grass snake would be pretty special!

If you could pick just a single thing or activity anyone could implement in their garden that would benefit wildlife, what would it be?

Grow a few native plants. Just one native tree can support hundreds of different species – providing flowers for pollinators, leaves for caterpillars and then seeds or fruit for birds in autumn. Not to mention shelter! Non-natives have a great role in gardens – especially for pollinating insects. But it’s the natives that attract the leaf munchers – the caterpillars, leaf miners, things that need leaves to breed. And, being at the bottom of the foodchain, these are hugely important to anything from hedgehogs to frogs, toads, newts, birds and bats.

What can cause the greatest harm or damage to wildlife living in, or wanting to live in your garden?

Erecting new fences and walls. If wildlife can’t get in to your garden, you’re closing off feeding and breeding habitat to them and potentially blocking off more gardens, too. Make sure wildlife can access your garden and chat with your neighbours so they know this too. Hedgehogs need just a four inch gap beneath or cut into a fence.

If your outdoor space is very small, what are the best ways to make even a tiny outdoor space a home to wildlife?

Grow a mix of nectar- and pollen-rich plants for pollinators, plus native plants for caterpillars. In a small garden you might have room for only one tree – try a Silver Birch or standard Hawthorn, which are great for wildlife. In courtyard gardens and balconies grow forget-me-not, primroses and foxgloves. These provide nectar and pollen for pollinators but also leaves for caterpillars to eat.

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

I’ve got an exciting project coming up that I can’t talk about yet – you’ll have to wait and see!

NHBS Guide to Dormouse Survey Equipment

Dormice are a distinctive family of rodents, found widely across Eurasia and Africa. The Hazel Dormouse (Muscardinus avellanarius) is a native British species which resides primarily in deciduous woodland. They are protected by EU law because of their rapidly declining numbers – studies suggest they have suffered a 72% population reduction in the last 22 years. Dormice are an important bioindicator as they are particularly sensitive to habitat and population fragmentation, so their presence is an indication of habitat integrity.

To enforce legal protection and ensure the success of conservation projects, current data about the distribution of Hazel Dormice is very important. A variety of survey equipment and methods can be used by licenced dormouse handlers and wildlife enthusiasts.

Nest Boxes

Perhaps the simplest survey technique to determine dormouse presence is searching for the nest box residents. Dormouse nest boxes are largely similar to standard bird boxes, but with the entrance hole facing the tree. Nest boxes can be important conservation tools as they can boost the local dormouse population density and aid re-introduction schemes.

The Standard Dormouse Nest Box is built from FSC softwood and has a removable lid with a wire closure for monitoring.

The box is also available with an added perspex screen. The perspex inner screen sits inside the lid and allows you to check the box for any inhabitants without any dormice escaping or being injured by quick replacement of the lid, especially when the box contains a mother and young.

Dormouse Tubes

Dormouse nest tubes are a cheap, easy and popular method of determining the presence of dormice within a habitat. They can be an effective alternative to using wooden nest boxes.

The tubes consist of a wooden tray and a nesting tube. Dormice make their nests in the tubes and it is these that are used as indicators of their presence in the habitat. Nest tubes can be set up and checked without a licence until the first evidence of dormouse activity is found. After that, only a licensed handler can check them. For attaching to a tree, Hook and Loop Strapping is a more environmentally friendly alternative to plastic cable ties, as they are reusable, reducing plastic waste.

Dormouse Footprint Tunnels

The latest dormouse surveying technique uses footprint tunnels. This technique was created by Suffolk Wildlife Trust with PTES funding and has since been recommended in the CIEEM magazine In Practice in September 2018.

It is a non-invasive survey technique, which does not require a licence as the chance of disturbing dormice is very low. The 40cm tube, houses a wooden platform which contains the charcoal ink and paper on which footprints are left. Compared with nest tube surveys, footprint tunnels can reduce the survey period required and provide an indication of the presence or likely absence of dormice at a site.

Dormouse Nut Hunting

Dormice leave very characteristic marks when they eat Hazel nuts. They gnaw a round hole in the shell leaving a smooth edge with very few teeth marks, unlike mice or voles. Systematic nut searches under Hazel trees are still regarded as one of the best survey techniques, only hand lenses and a keen eye are required.

Accessories and books

Below are some accessories and books that are commonly used for dormouse surveys and monitoring:

Small Mammal Holding Bag

Pesola Light-Line Spring Scales

Pesola PTS3000 Electronic Scale

Heavy Duty Extra-Large Polythene Sample Bags

Animal Handling Gloves

LED Telescopic Inspection Mirror

Author interview with Benedict Macdonald, Rebirding: Restoring Britain’s Wildlife

Did you know that 94% of Britain isn’t built upon, that Snowdonia is larger and emptier than the Maasai Mara National Reserve, or that Scotland’s deer estates alone cover an area twice the size of Yellowstone National Park?  Britain has all the empty space it needs for an epic wildlife recovery.  So what’s stopping it from happening in our country – and how can we turn things around? 

 

Rebirding: Rewilding Britain and its Birds is a bold roadmap to reverse the decline of bird populations in Britain, suggesting we need to restore ecosystems, rather than modify farmland.

Author, Benedict Macdonald offered his valuable time to answer our questions about his important new contribution to the discussion of rewilding.

Rebirding Author: Benedict McDonald

What inspired you to become so passionate about restoring natural ecosystems?

In 2014, I began writing Rebirding in the certain knowledge that conservation in this country is failing, the birdsong around us is dying out every year, yet we have all the resources, skill and wildlife lobby to turn things around. I hope that in its small way, Rebirding will do for the UK what Sir David Attenborough’s Our Planet is beginning to do for worldwide conservation – to make people realise that nature is essential, profitable and saveable, even now – and that we have all the resources and skill to do so.

Tell us a little about your background and how you became interested in the natural world?

I never remember the moment of first being fascinated by nature, but I do remember that by the time I was five, I would make weekend visits to Berkeley Castle Butterfly Farm and was entranced by watching the butterflies drinking salts from my fingertips, and I began a collection of ones passed to me by the lady running it – after they had died.  Then early trips to the Welsh coast, and Norfolk, transformed that interest into a lifelong love of birds as well.  From there, their plight has drawn me into understanding and studying ecosystems and a far wider understanding of protecting nature.  Since then, my love of the natural world, both as a naturalist and a TV director, has now taken me to over forty countries.

At 14, I first remember telling someone at a dinner party that I wanted to work in wildlife television. Since graduating from university, I’ve been lucky to work on a range of programmes such as Springwatch, The One Show and The Hunt for the BBC.  Last week, aged 31, I attended the premiere of Sir David Attenborough’s Our Planet for Netflix, launching in the Natural History Museum in London. This is the largest conservation series ever made. I work as the researcher and a field director for the Jungles and Grasslands episodes, directing a number of sequences including desert-nesting Socotra cormorants, the secret life of the Alcon Blue butterfly, and the remarkable lives of the world’s only tool-using Orangutans.

In your opinion, what is the most detrimental practice to the wildlife of Britain?

We are often sold the untruth that what happens to British land is necessary for food production. This is almost entirely untrue.  Only the profitable arable farms of the south, and east of our island, provide a bounty of food for our children.  Dairy lawns and sheep farms in fact create tiny volumes of our daily diet relative to the land area they use. For example, 88% of Wales grows lamb, an optional food resource. 

Of the epic wastage, however, the grouse moor is the ultimate. Eight percent of Britain’s land is burned for the creation of 0.0008% of its jobs and a contribution of just 0.005% to our GDP.  For hundreds of years, thousands of beautiful wild animals have been removed, just so that Red Grouse can be turned into living clay pigeons and killed in their thousands once a year.  Even hunters from other countries find this wasteful and disgusting.  This area covers an area twice the size of Yellowstone National Park – blocking jobs and wildlife alike on an epic scale. Hunting estates in Finland or Sweden, by contrast, juggle the ambition of hunters to shoot a few animals with ecosystems of immense beauty and variety.

Wildlife and commerce are often presented as being in conflict, do you think this is a fair assessment, or can land stewardship that favours biodiversity over profit be of economic benefit?

This is surely the greatest imaginary conflict of our time, successful insinuated, perhaps, by the damaging economies that prevent nature from reaching its full economic potential in our country.  In truth, wildlife IS commerce.  Nature IS money. 

Every year, even without a single charismatic megafauna such as Bison, Elk or Lynx running wild in our country, without a ‘Yellowstone’ or ‘Maasai Mara’, the English adult population make just over 3 billion visits to the natural environment each year, spending £21 billion as they do so. In Scotland, nature-based tourism is estimated to produce £1.4 billion per year, along with 39,000 FTE jobs. 

In contrast, the current models of upland farming demand money from us to survive, but they do not reciprocate jobs, income or natural capital – this is life on benefits and there is no future for young people in it.  In contrast, wherever nature is allowed to flourish, it’s capital potential is wondrous.  In 2009, the RSPB’s lovely but very small reserves brought £66 million to local economies, and created 1,872 FTE jobs. This is more than all of England’s grouse moors, but in just a fraction of their land area.

Right now, however, we are just seeing snapshots of how nature can power and rekindle communities. In Rebirding we often look to other countries to see how true ecosystems could transform economies on a far greater scale.   The final myth that we kick into touch is that Britain is short of space, 94% of our country is not built upon. Most of this area does not create essential food supplies – and is jobs-poor.

Is there one single practise or cultural shift that would be of most benefit to restoring natural ecosystems?

The Forestry Commission is the largest single land manager in Britain.  It now needs to split its forests in two – rewilding key estates like the New Forest and the Forest of Dean: cutting down the spruce and replanting with native trees, then, crucially, leaving large native animals such as Beavers, Elk, cattle and horses to become the foresters.  Economies in these forests would be driven through ecotourism revenues and perhaps some hunting.  Elsewhere, timber forests would remain.  It is hard to think of one single decision that could effect a greater transformation on British land than a decision to return Britain’s once world-class oak-lands to our nation.  Another, however, would be if Scotland’s deer estates, which again cover an area twice the size of Yellowstone, could be incentivised to rewild and regrow their trees.  Hunting could remain – but in this regrowing wilderness would be the potential for Elk, Lynx, Wildcats and a huge expansion in woodland species like Capercaillie. 

Are you optimistic for the future of Britain’s wildlife?

Yes – but only if our conservationists act with the same pragmatism and determination as those who have prevented land reform for decades.  In my closing chapter, I’ve argued that whilst farming unions behave with absolute conviction and coherence, our nature charities often simply say that a few more Skylarks would be nice.  Only if we can unlock the economic arguments of nature, and harness the millions of voices effectively, will we see large areas rewilded in our country.  It is the social and economic transformation that nature provides that needs to be realised – but for that, you need space, and power over land.  At that moment, things will change. In my lifetime, I genuinely believe that after many fierce battles, we will see Dalmatian Pelicans flying over Somerset, and huge areas of Scotland, Wales and upland England slowly returned to a wilder state.  But without absolute conviction this is possible, it will never come to pass.

Supporting Conservation: National Museum of Brazil

On 2nd September last year, a terrible fire destroyed the National Museum of Brazil in Rio de Janeiro. Alongside the vast collection of irreplaceable natural history specimens, the fire also destroyed books and equipment used by the Museum’s researchers for ecological research and wildlife conservation.

Thankfully as museum curator, Débora Pires, wrote shortly after the incident: “The brains did not burn; we are working with a positive agenda!”

A selection of books kindly donated

NHBS were approached by our former director Alan Martin, who provided a list of products which the malacology, arachnology, entomology and lepidoptera departments needed to get back on their feet. Alan, now secretary of the Brazilian Atlantic Rainforest Trust (BART) has close links with many researchers at the museum.

Following this, we decided to coordinate an effort to provide the items that are most critical to their research. We contacted suppliers asking them to contribute and we agreed to supply our own manufactured products, and cover shipping costs of all donated items.

The response from suppliers was fantastic, as the majority were happy to donate all, or most of the items requested. We would like to give huge thanks those who have donated so far: Elsevier, BIOTOPE Parthenope, Brunel Microscopes Ltd, BugDorm, CABI Publishing, Harvard University Press, the Royal Museum for Central Africa, Watkins & Doncaster and finally EntoSphinx. So far, we have received just over £2,000 worth of items, with more to follow.

A selection of items that are being sent in the first shipment.

“I’m really sorry to hear such devastating news. This is truly awful and it’s good to see you are providing such great support to them. We would be happy to send out the [requested] book gratis.” – Linda Jackson, Elsevier

NHBS Guide to Night Vision and Thermal Optics

There are many scenarios where our attempts to observe and survey certain species are hampered by our limited sensory systems. Many animals are difficult to detect because they utilise cryptic colouration or disruptive patterns, or they have evolved ingenious behaviours to conceal themselves within their environment. In other cases, environmental conditions such as low light levels or fog, can reduce visibility and disguise even some of our most obvious resident species.

Ecologists, researchers and amateur wildlife enthusiasts have overcome these sensory limitations by using thermal imaging and night vision optics. This article will cover how these different technologies function, highlight their key specifications and give recommendations for those looking to purchase one of these devices.

Thermal Imaging

Thermal imaging works by using an electronic detector element to convert the infrared light (heat) emitted by objects in the environment into a visible pattern of colours that vary depending on the temperature of the object. Thermal imaging devices (TIDs) are becoming increasingly common in ecological surveys because, unlike night vision devices, they can produce an image in daylight or complete darkness, even through fog.

When choosing a TID there are a few key technical specifications that you should consider for your project:

  • Resolution – The clarity of the images/videos is determined by the number of heat sampling points. The higher the resolution, the easier it is to spot small animals at a distance.
  • Refresh Rate – Determines how often the screen is updated with a new image. A refresh rate of 30Hz or more is recommended for fast-moving animals such as birds and bats.
  • Zoom – This is particularly useful for larger species identification and counting your target more accurately.
  • Field of View (FOV) – The horizontal and vertical angle of view that you can see through the thermal imaging device. A wider field of view is useful when detecting small animals.
  • Maximum Detection Range – Gives an indication of how far the device will be able to detect a human-sized object effectively.

Night Vision

Night vision technology operates either by using an image-intensifier tube (analogue) or an electronic sensor (digital) to amplify the small amount of light present in dark environments to generate a bright image. They typically produce a monochromatic green or greyscale image, however some newer technologies are now able to capture colour images in low light conditions.

There are a few specifications that you should consider when choosing an night vision device (NVD):

  • Viewing Range – The distance to which you can see and distinguish objects using the device can be crucial for certain projects. A low-end NVD will typically have a viewing range of around 200m, while more high-end models can achieve viewing ranges of up to 500m.
  • Analogue Night Vision – These scopes are grouped into generations. Gen 1 scopes are the most economic but have a limited range (approximately 75m), lower resolution and limited field of view. Gen 2 and 2+ scopes offer performance improvements such as longer range, better image resolution and greater field of view.
  • Digital Night Vision – Digital devices typically produce higher quality images than Generation 1 scopes, often have a video output or SD card allowing video capture.
  • IR illumination – Most night vision devices have a built-in IR illuminator to increase the brightness of the images it takes, however purchasing an additional IR illuminator may be necessary when working in extreme darkness.

BSBI: Publisher of the Month for April

 

 

 

 

With Spring finally upon us, NHBS are delighted to announce the Botanical Society of Britain & Ireland (BSBI) as our Publisher of the Month for April.

BSBI: Origins and Aims

The BSBI has a long and illustrious history as a publisher of books and periodicals aimed at both professional and amateur botanists. Tracing its origins back to 1836, the society was founded as the Botanical Society of London; from its earliest days, the BSBI has welcomed and supported everyone who wants to know more about the British and Irish flora. The society’s training, outreach and research  programmes continue to support botanists at all skill levels.

BSBI Publications

 

 

 

 

The BSBI publishes a range of botanical books; their BSBI handbooks have become standard botanical field guides, containing identification keys, detailed plant descriptions and useful line drawings, together with information on habitat and distribution. They also publish important stand-alone titles, such as Hybrid Flora of the British Isles and Threatened Plants in Britain and Ireland.

The BSBI have been instrumental in helping to publish John Poland’s critically acclaimed The Vegetative Key to the British Flora and most recently, after years of work, The Field Key to Winter Twigs – both vital reference for field botanists.

Forthcoming Publications: BSBI Atlas 2020

The first atlas of the British and Irish flora was published in 1962. It pioneered the use of ‘dot-maps’ aligned to the OS grid which influence  the hundreds of natural history grid-based atlases that followed.  Work has already started on a third atlas; Atlas 2020  will be published after fieldwork has been completed in 2019. You can find out more, or even get involved by visiting their website.

 

You can browse all the BSBI publications here

Find out more about BSBI

The BSBI is passionate about the flora of Britain and Ireland and encourages everybody to become involved.  If you are a novice and want to get started in botany, their get started page is definitely worth a visit.  And if you want to put your botanical knowledge to use, opportunities for volunteers can be found here.

BSBI’s blog often features interviews with authors such as Kevin Walker, author of Threatened Plants in Britain and Ireland and John Poland (The Field Key to Winter Twigs).

New bird, bat and bee boxes for 2019

Providing nesting and roosting spaces for our wildlife is increasingly important as natural habitats and nest spaces are diminishing. Luckily, with the huge range available today, boxes for birds, bats and even bees can be sited almost anywhere from a tree in your garden, to within the walls of a new building and even free-standing. Below we will take a look at some of our newest bird, bat and bee boxes and what they can be used for.

introducing the Integrated Boxes by Green & Blue

The Bat Block

Green & Blue have just released two brand new products ready for this Spring.  Designed to be simple and easy to fit within the framework of new builds, the new Swift block and Bat block are sleek and made from recycled materials from the Cornish china clay industry. Both are standard UK block size and have slightly protruding entrances.

Green & Blue BestSellers

As well as their new swift and bat boxes, Green & Blue also sell a range of blocks for bees. The blocks are made of 75% waste materials from the Cornish china clay industry and features small holes that appeal to a range of solitary bee species. The blocks range from small, brick-shaped blocks that can be built into walls or buildings, to large, stylish posts reaching 2.3m high, to plant pots that have space for you to plant bee-friendly flowers next to the solitary bee nesting holes.

New additions to the Eco Range

The ‘Eco’ range of boxes has recently expanded to feature a new Eco Bat Shelter and an Eco Tawny Owl Nest Box. These boxes are made of recycled plastic and the bat shelter comes in both a standard black and a brick-red colour. The bat shelter features a ceramic insert that helps to stabilize the internal temperature and is self-cleaning. The tawny owl nest box contains an FSC certified wooden nesting chamber which features built-in drainage holes meaning maintenance can be kept to a minimum. 

Aside from the new bat shelter and Tawny Owl nest box, the Eco range also includes a variety of boxes to cater for a wide range of bat and bird species. All of which are made from 100% recycled plastic and FSC certified wood and wood composite internal chambers. Click the images below to find out more.

Integrated Habibat 003 Blended Box

The Habibat 003 is based upon the original Habibat box but features a blended facing to allow it to fit more seamlessly in building where the brickwork is built using stretcher/blended bond. The box provides the same internal roost space with insulating concrete and comes in a choice of three popular colours: smooth blue, smooth red or buff. If you have a more specific brick requirement or would like the box to match exactly your batch of bricks, the 003 is available with a custom facing where you can send your own bricks to be used or provide your brick code for the manufacturers to use on your box.

NHBS Guide: How to choose a Trail Camera

As we enter the warmer spring months many of the UK’s mammals become more active as they establish territories, build nests and find mates. Despite all this activity, observing and surveying these animals is often a challenging task. Trail cameras offer an easy, effective and non-invasive solution in many of these situations, earning their place as an essential kit piece for any ecologist or wildlife enthusiast.

Listed below are a selection of new models and old favourites from each of our trail camera ranges. The primary features we find useful to distinguish between models are:
–  whether the camera has a colour viewing screen for reviewing footage in the field
– whether the camera has low glow LEDs (better flash range and video quality) or no glow LEDs (totally invisible to the human eye)
– trigger speed (how quickly the camera takes a still image once the infrared is triggered
– recovery speed (if known, how quickly the camera takes a second picture)
– video quality and framerate (video footage at 60fps is noticeably smoother)

Accessories

A number of accessories can be bought to help mount and secure your trail camera your camera in the perfect position.

Python Mini Cable Lock

Python Mini Cable Lock
Compatible with all of our retailed trail cameras. This versatile lock has been designed to be extremely resilient to damage and picking, protecting your camera from any potential theft.

Security Boxes
Many of our trail cameras can be contained within a matching security box which provides maximum protection when in the field. All of our security boxes can be locked using a standard padlock or python cable. Make sure when purchasing a security box that it will fit the intended trail camera.

See our full range of Security Boxes on our website.

Batteries
The batteries you use in your trail camera can influence its performance in the field. Lithium-ion batteries are one of the most popular choices because they produce a high voltage per cell (1.6v) giving a brighter LED flash and a greater flash range. Rechargeable alkaline batteries offer a more economical and environmentally friendly alternative, however, when in use their voltage decreases over time and they produce proportionately darker LED flashes and consequently, photographs/videos are less illuminated. Standard alkaline batteries are also a suitable economic alternative.

SanDisk Class Cards
Ensuring you use a high read-write speed SanDisk Class card is highly advised for all of our trail cameras. Be sure to check the maximum SD or SDXC card capacity for your intended camera as these can vary between models and brands.

Solar panels
Where sufficient sun is available, the addition of a solar panel to your trail camera can extend its recording life indefinitely. Browning, Bushnell, SpyPoint and Ltl Acorn all offer compatible solar panels for their trail cameras.

All of our trail cameras can be purchased as starter bundles which include an SD card and all the batteries you need to power the camera. The complete trail camera range can be found at www.nhbs.com
