Best Bird Boxes for Different Species

This guide is designed to help you choose the best bird box, based on the species of bird that you are hoping to attract, or that you know can be found in your garden or other outdoor space. Species are organised alphabetically by common name, and for each one we have included information about the preferred type of box and siting location. You will also find a handy list of suitable boxes available from NHBS.

The NHBS Guide to Hand Lenses

The possession of a hand lens is one of the defining characteristics of a naturalist.

We use them for everything from peering at beetle genitalia and examining floral characters, to examining the arrangement of teeth in small mammal jaw bones. There are a wide variety of hand lenses on the market so how do you decide which lens is best for you? This article contains all the information you need to make an informed choice.

Glass versus plastic lens?

The optical lens in a hand lens can be made from glass or plastic. Plastic lenses are generally more affordable and lighter but are of lower optical quality and are more difficult to clean. Plastic hand lenses, however, can be a good choice for schools and young children.

How many optical elements?

Canon 400mm

An element is an individual piece of glass within a lens. When you look through a high quality camera lens you will typically be viewing what’s in front of the lens through four to six lens elements, as well as other elements used for focusing and zooming (see image below right).

Paul Canon EF 400mm f/4 DO IS USM By Paul Chin

Hand lenses are constructed with one (singlet), two (doublet) or three (triplet) lens elements. Each one is specially shaped to correct for a particular type of optical distortion, so the more elements, the higher quality the image.

Magnification

A 10x magnification hand lens will be more than adequate for most purposes. Higher magnification lenses tend to be harder to use but are very useful for viewing extremely small objects. If you are unsure of which magnification you need, or think you may need several different lenses, you might consider the Duel Singlet Loupe (x10 and x20) or the Triple Hand Lens (x3, x4 and x5).

Lens diameter

Large diameter lenses provide a wider field of view which means that they are easier to use but they are slightly more expensive to produce.

How hand leOpticron Hand lens, 23mm, 10x magnificationnses are named

Hand lenses are named in the same way as binoculars, with both the lens diameter and the magnification included in the name. For example, the Opticron Hand lens, 23mm, 10x magnification has a 23mm diameter lens and provides 10x magnification.

Using your hand lens

Finally, a quick note on hand lens technique. To use your hand lens correctly, hold the lens close to your eye and then either a) move the subject closer to your eye until it comes in to focus or b) move your head (and the hand lens) closer to the subject until it comes into focus. It’s easy with a little practice so don’t get put off if you find a new hand lens difficult at first. Expect to get close up to what you’re examining – it’s quite common to see naturalists crawling around on the ground to get close to a plant they’re identifying.

Keeping your hand lens safe

It can be very hard to find a much-loved hand lens dropped in long grass or woodland. To prevent this happening, we recommend a lanyard for your hand lens – this has two functions: a) if you have it round your neck you won’t drop it, and b) if you put it down somewhere the bright blue lanyard is easy to spot.

The table below provides a guide to the hand lenses sold by NHBS. More information and specifications of each can be found by following the links. Our full range of lenses and magnifiers can be found at nhbs.com.

The NHBS Guide to Small Mammal Trapping

Field vole (Microtus agrestis)

Small mammals form a vital component of our terrestrial ecosystems, both by contributing to overall biodiversity and providing prey for carnivores such as owls, pine martens and weasels. Survey data for many of our small mammal species is insufficient for them to be assessed as part of the UK BAP process and so supporting our national monitoring programme is incredibly important.

One of the most common ways of monitoring small mammals is through the use of live traps. These allow a range of species to be monitored simultaneously, and also allow biometric data such as weight and sex to be collected. In addition, estimates of population size and structure can be calculated using capture-mark-recapture (CMR) techniques. The use of live traps is also a great way for getting volunteers involved and providing them with an up-close experience of the animals they are passionate about.

Live-catch techniques, however, do have a few disadvantages in that populations can be affected by disturbance or mortality. Live-trapping is also unsuitable in certain areas (such as urban or busy rural regions) and requires a relatively large amount of time and expenditure.

Here we will take a look at some of the most commonly available live-traps used for small mammal survey.

Longworth Trap

Longworth Small Mammal Trap

The Longworth trap is made from aluminium which makes it lightweight for field use. This trap has been widely used in the UK for many years.

The trap consists of two parts: a tunnel which contains the door tripping mechanism, and a nest box, which is attached to the back of the tunnel. The nest box provides a large space for food and bedding material to ensure that the trapped animal is comfortable until release.

Advantages
• Widely used for many years; well documented in scientific literature
• Lightweight and durable
• Sensitivity of the trip mechanism can be adjusted
• Door can be locked open for pre-baiting

Disadvantages:
• Expensive
• Replacement parts not available
• Larger species can occasionally trip the trap without being caught
• Pygmy shrews may be too light to trigger the trap mechanism

Sherman Trap

Sherman Trap

Sherman traps work by use of a triggered platform which causes the door to shut when the animal enters. It folds down to a size and shape which is easy to transport.

Sherman traps are available in a range of different sizes to suit the species that you are hoping to catch. They can be purchased in aluminium or as a galvanised version which is more resistant to rusting.

Advantages:
• Lightweight and foldable – easy to transport and store
• Different sizes available, including long versions
• Easy to clean

Disadvantages:
• Difficult to add bedding/food as this interferes with the trap mechanism
• Traps may distort over time with repeated folding
• Danger of long tails being trapped in the door

BioEcoSS TubeTrap

The TubeTrap is a relatively new addition to the mammal trapping range and features an innovative design. It provides a safe method of trapping even the smallest mammals such as shrews.

The robust plastic construction has self-lubricating and fully replaceable parts. It can be purchased either with or without a shrew hole in the door. Spare doors are also available which means that you can convert the trap between shrew and non-shrew versions quickly and easily.

Advantages:
• All parts are easily user-replaceable
• Door can be locked open for pre-baiting
• Trigger sensitivity is easily adjustable; suitable for pygmy shrews
• Green colour of trap makes it inconspicuous in the field

Disadvantages:
• Door is a little fiddly to set – particularly for larger fingers
• Relatively new design means it has been tested fewer times in the field in comparison to Longworth or Sherman Traps

Economy Mammal Trip-Trap

Economy Mammal Trip-Trap

The Economy Trip-Trap provides a cheaper alternative to other mammal traps.  It has a traditional treadle design which closes the door behind the animal when it enters the trap.

This lightweight trap is suitable for short-term or occasional use and is also popular for trapping mice indoors either for surveying or for relocation.

Advantages:
• Cheap and lightweight
• Transparent for easy inspection
• Good for indoor use

Disadvantages:
• Doesn’t work well in wet/humid conditions
• Can’t pre-bait or change trigger sensitivity
• Trapped animals may chew through the trap

Pitfall Traps

P2.5 litre Plastic Bucketitfall Traps consist of a container which is sunk into the ground, into which small mammals can be caught. Traps can be baited if required and drift fencing can also be used to direct animals into the trap.

Small cans or buckets make ideal pitfall traps. If using buckets, lids can be fitted when not in use, which means that traps can remain in situ for extended periods of time.

Advantages:
• Able to catch multiple individuals
• Low maintenance

Disadvantages:
• More labour intensive than box traps to set up
• Trapped animals may attack eachother or be eaten by predators
• May become waterlogged in damp areas or in bad weather

Other survey methods

Other methods of surveying for small mammals include the analysis of owl pellets for mammal remains and the use of dormouse nest tubes. Hair and footprint tubes are also useful as well as searching for field signs such as tracks and faeces.

A comprehensive monitoring programme will most likely involve a combination of these methods, depending on the availability of participants and volunteers and the type of habitat present locally.

If you are interested in becoming involved in mammal survey in the UK, take a look at the Mammal Society website where you will find information on local recording groups, training opportunities and the latest mammal-related research.

Our full range of mammal traps can be found on our website.

 

What’s new for 2017 – Trail camera news

The days are getting longer and the clocks are set to British summer time here in the U.K. With the arrival of the warmer weather, our local wildlife is also becoming more active and now is a great time to set up a trail camera to see what’s going on in your garden or local outdoor space. If you’re lucky you may even spy young animals emerging from their burrows for the first time.

In this article we will take a look at some of our new and favourite trail cameras for 2017.

Bushnell Trail Cameras

This spring has seen a new range of cameras arrive on our shelves from Bushnell, featuring an exciting selection of brand new features.

The new Trophy Cam Aggressor range is available in four models. All of these share an excellent 0.2 second trigger speed and a recovery time of just 0.5 seconds, ideal for moving animals. A new Dynamic Video function means that the camera will record continuously while there is a subject in the detection range and an Auto Exposure function helps to avoid bleached out images when the subject is too close. Three preset functions allow easy configuration of advanced settings based on the location of the camera (choose from trail/scrape, feeder or food plot). The design of the case has also been improved with a strengthened cable lock channel, stronger latch and illuminated button panel.

The four models differ in their image/video resolution, type of night vision LEDs, screen type and case colour. Take a look at our handy guide below to see which is the right model for you.

Spypoint Trail Cameras

Spypoint produce consistently high quality cameras and their range features several models that are exciting for wildlife enthusiasts.

Spypoint Force-11DThe Force-11D has an unbeatable trigger speed of just 0.07 seconds and an adjustable detection range of 1.5m to 24.4m with a curved motion sensor to improve the detection angle. 11MP images and 720p, high definition video can be captured while no glow LEDs make your camera completely inconspicuous.

 

Spypoint SolarThe Spypoint Solar provides another fantastic option, particularly if you want to leave your camera unattended for extended periods of time. The built-in solar panel will power the camera any time that the sun is shining, only switching to battery power at night or when there is insufficient sunlight. A 2″ colour screen lets you preview your images in the field.

 

All of our trail cameras can be purchased as a starter bundle 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

Great Crested Newt eDNA Service with Nature Metrics

Great Crested Newt by Chris H is licensed under CC BY 2.0
What is eDNA?

eDNA or environmental DNA is genetic material found in the environment. This DNA comes from organisms in various forms including (but not limited to) faeces, mucus, gametes, shed skin or hair. Although eDNA degrades over time, it can persist long enough for its presence to be tested from environmental samples.

eDNA sampling for Great Crested Newts

Sampling and testing of eDNA in pond water is a relatively new, but increasingly popular, method of determining presence of Great Crested Newts. Provided that the sampling and analysis protocol complies with DEFRA guidance and that samples are collected between 15th April and 30th June, then eDNA test results are accepted by Natural England and Natural Resources Wales.

Unlike traditional methods of bottle trapping or torch searches, collecting pond water samples for eDNA analysis has very low impact on newts and other pond inhabitants. It also has obvious benefits in terms of labour time, and ecologists are less restricted to specific times of day for surveying. It could also provide a more accurate method of determining the presence of Great Crested Newts which are notably difficult to survey reliably. The technique is not without limitations, however, and can be problematic in ponds with large amounts of algae or sediment or where accessibility is a problem.

How do you collect and analyse eDNA samples?

The sampling process involves the use of a sterile ladle to collect 20 samples of pond water which are then mixed together in a bag. A small volume of this pond water is then added to each of six tubes containing a preservative solution and control DNA. These tubes are returned to the lab where quantitative PCR (qPCR) is used to amplify and measure the GCN DNA (if present), thus determining the presence of GCN eDNA in the samples.

NHBS and Nature Metrics

This spring, NHBS will be working with Nature Metrics to provide a complete GCN eDNA analysis service. Combining our expertise in sourcing, packing and shipping equipment with the excellent laboratory proficiency of Nature Metrics, this partnership will allow both teams to focus fully on our strengths in order to provide a fast and efficient service.

How to choose a nest box camera

Nest box cameras provide an excellent way to observe the exciting nest building, egg laying and chick rearing behaviours of your local birds.

Deciding which nest box camera to choose can be confusing and several questions should be considered before you make your choice: Do you need a wired version or would a wireless option be best for you? Do you want a camera that you can fit into an existing box, or would you prefer to buy everything already assembled? Will you be able to view your footage on your PC or laptop? Do you want to stream your footage to a website? In this article we will address all of these FAQs and offer some simple advice to make sure that you get the best out of your camera.

Do you want a wired or wireless system?

Wired systems have a cable running from the nest box back to your house or classroom. This cable carries both the power to the camera and the signal from the camera to your TV. A wired setup offers excellent image quality but may not be ideal if you have children or pets in your garden or if a cable running to your bird box will interfere with the gardening. You will also need to feed the cable into your house, either by drilling a hole in the wall or by feeding it through an open window.

Wireless systems do not require a cable between the bird box and the television but instead transmit images to a small receiver situated inside the house. For some cameras, such as the Wireless Nest Box Camera Kit, a power supply will still be required for the camera (i.e. from a shed or outbuilding). Other cameras, such as the battery powered Wireless Nest Box Camera Kit have solved this problem by adding a battery box, allowing the camera to run off D-cell batteries. An advanced version of this camera system is also available. This includes a solar panel which will power your camera while the sun is shining, only switching to battery power at night or on dull days.

Another thing to consider with a wireless system is that the signal can be compromised by other wireless devices in the area or by trees and other structures between the nest box and the house. In some situations this can severely affect your image quality.

Do you want a complete kit or just the camera?

If you are new to this particular aspect of watching and listening to birds, a complete kit, such as the Nest Box Camera Starter Kit or the Wired Camera Bird Box, provide an excellent and economical choice. These kits include a bird box which has a camera ready mounted in the roof. An attached cable plugs into your television and supplies the camera with power. Alternatively, if you want a wireless option, the Wireless Camera Nest Box is a great choice and doesn’t require any complicated assembly processes.

For the handyman or woman who wants to put a system together themselves, either in a bespoke or existing nest box, the Nest Box Camera with Night Vision is a good choice. The camera comes with a 30 ­metre cable and extension cables are available to purchase separately. The Wireless Nest Box Camera Kit or the battery powered Wireless Nest Box Camera Kit are good options if you want to fit a wireless camera into your own bird box.

If you decide to go for one of these options then you will need to attach the camera to the ceiling or inside wall of your box yourself using small screws. A small file can be used to file down a part of the side wall to make a space for the cable to pass through. Alternatively you might consider buying a Camera Ready Nest Box which has a clip inside for attaching a camera, as well as a perspex window in the side which helps to improve the quality of daytime images.

What about watching on your computer?

All of the cameras and kits that we sell come with either a cable or wireless receiver that will connect directly to your television. If you want to view or save your footage onto your computer then an additional USB capture device is required. These allow you to connect your camera/receiver to the USB port of your computer and come with viewing software which allows you to watch and record your footage. Available for both Windows and Mac operating systems.

Can I stream my footage to a website?

There are lots of online services which allow you to stream a live feed from your camera online. Many are free if you are happy having adverts on your stream, or you can purchase a monthly or yearly ad-free plan. Our current favourite is Ustream (www.ustream.tv). Take a look at their website for lots of great resources to help get you started.

 

 

New Bat Detectors for Spring 2017

It’s that time of year again. Spring has sprung earlier than ever, and the survey season will very soon be under way. In this post we look at some of the fantastic new bat detectors due for release this spring.

Anabat Swift

The Anabat Swift from Titley Scientific is based on the excellent design of the Anabat Express and records in full spectrum as well as zero crossing. Users can choose between sample rates of 320 or 500kHz and a built-in GPS receiver automatically sets the clock, calculates sunrise and sunset times and records the location of the device.

 

Echo Meter Touch 2

The Echo Meter Touch 2 is perfect for bat enthusiasts and students and will let you record, listen to and identify bat calls in real-time on your iPad, iPhone or iPod Touch. All you need is your iOS device, your Echo Meter Touch 2 and the Echo Meter Touch App which is a free download from the iTunes store.

Echo Meter Touch 2 Pro

Designed for consultants and professional bat workers, the Echo Meter Touch 2 Pro has all the great features of the Echo Meter Touch 2 but with additional user options such as an adjustable sample rate (256kHz and 384kHz), adjustable gain and advanced trigger settings.

Batcorder Mini

The compact Batcorder Mini has a very simple user interface with just a single button to start and stop recording. Calls are recorded in full spectrum onto the built-in memory (64GB) and the internal lithium-ion battery is chargeable by USB. A built-in GPS receiver sets the time, date and location.

Ultramic384 Ultrasound Microphone

This high performance ultrasound microphone will connect to a USB port for real time listening and can also be used as a stand-alone recorder when used with a USB battery. An internal microSD card slot allows data to be recorded.

Batcorder GSM

The Batcorder GSM is designed for use at a wind turbine site and includes a microphone disk which is inserted directly into the turbine nacelle. The unit runs off mains power from the turbine and a GSM function lets you receive status messages, reassuring you that everything is recording correctly. A Raspberry Pi setup also lets you backup your files to a memory drive and download data directly or over an internet connection.

The NHBS Guide to Moth Traps

Flatpack Skinner Moth Trap with Electrics
The Flatpack Skinner Moth Trap is made from FSC timber and is easy to assemble.

In this brief guide we will take a look at the main types and designs of moth traps. We will also address many of our most frequently asked questions, including why you will no longer find Mercury Vapour traps for sale at www.nhbs.com

Robinson Moth Traps

Twin 30W Actinic Robinson Moth TrapRobinson Traps are the preferred choice amongst many serious entomologists because they offer the highest retention rates. On a very good night you may catch in excess of 500 moths. They tend to be more expensive that other types of trap, however, and they are also quite large. They also cannot be collapsed down for storage or transport. The Robinson Trap is available with twin actinic bulbs and is powered by 240V mains electricity.

Skinner Moth Traps

Mobile 15W Actinic Skinner Moth TrapSkinner Moth Traps will attract a similar number of moths to Robinson Traps. However, they are less efficient at holding the catch. The main advantages of Skinner Traps are price and portability, and they also let you access your catch whilst the trap is running. Skinner Traps collapse down quickly and easily when not in use, making them very easy to store and transport. They are available with actinic electrics and can be provided with either 240V (mains powered) or 12V (battery powered) control panels. Lucent traps have a clever design with all components fitting neatly into a suitcase-style case.

Heath Moth Traps

6W 12V Portable Heath Moth TrapThe traditional Heath Moth Trap has a small actinic tube mounted vertically within three vanes that work together to attract and then deflect moths downwards into the holding chamber below. The traps are very lightweight and portable and are usually powered by a 12V battery or generator, although mains powered traps are also available. Variations on the Heath Trap design include the “Plastic Bucket” model which allows the trap to be packed away and carried conveniently. Although catches from Heath Traps tend to be less than for Robinson and Skinner traps, due to their lower wattage bulbs, their affordability and portability makes them great choices for beginners or for use in the field.

Moth Collecting Tents

Moth Collecting TentMoth Collecting Tents provide a unique alternative to traditional style moth traps and are ideal for educational use or group trapping events. They consist of a large white fabric structure which is fitted with a UV light source. Moths which are attracted by the light settle on the white fabric and can be observed or collected for study. As the collecting area is large and accessible, it is easy for many individuals to view the specimens at the same time. However, tents and sheets do not have the same retention rates as traditional box-type traps.

Moth Trapping FAQs

What kind of trap is best for garden or educational use?
The design of the Skinner Trap means that you can access the catch without having to switch off the bulb. This is particularly useful if you are looking at your catch over the course of the evening, rather than leaving the trap all night and returning to it in the morning. Skinner Traps also have the added benefit of collapsing down, making them easier to store.

Which trap is best for unattended trapping?
The Robinson Trap is the only trap that will retain the whole catch after dawn. Some moths will escape from other trap designs.

Which trap is most portable?
Heath Traps are the smallest and easiest to transport. They can also run off a 12V battery, allowing them to be used in remote sites. The Safari and Ranger Moth Traps are the smallest and lightest traps we sell, so are ideal for travelling, however, they do require mains electricity (or a generator) to run.

Why can I no longer find Mercury Vapour traps on your website?
Mercury Vapour bulbs have recently been phased out as part of the Restriction of Hazardous Substances Directive. Therefore, we have removed the traps from our range and are now focussing on actinic replacements. If you have a Mercury Vapour trap and would like to convert it to run with actinic electrics, please get in touch with us to have a chat about this.

What are actinic bulbs?
Actinic bulbs product a small amount of UV light alongside the visible light which makes them more “attractive” to moths. They are not as bright as Mercury Vapour bulbs but because they don’t get as hot they are much safer to use, particularly for public and attended trapping events. They are also much less of a disturbance to neighbours if you are using the trap in your garden.

What is the difference in catch rates between the different traps?
The Robinson Trap and Skinner Trap will attract a similar number of moths but the Robinson has the highest retention rate of the two. Heath Traps will retain fewer moths but will still attract the same range of species. You can therefore obtain similar results trapping for a longer period or over several nights in the same area.

Do different traps attract different species?
No, all traps using actinic electrics will attract the same range of species. However, species of macro-moth from different families have been shown to vary in the extent to which they are attracted to a light source. This means that care must be taken when estimating local abundance from the relative abundance of species in your trap as some species will be attracted from a wider area than others.

NHBS Staff Picks 2016

Welcome to our annual tour of recommended reads and equipment highlights brought to you by members of the NHBS team. Here are our staff picks 2016!

The Sauropod Dinosaurs: Life in the Age of Giants

I admit that I’m a bit of a closet palaeontologist. Having decided to forego a career in this field in favour of biology, I have nevertheless retained a fascination for dinosaurs, so I enjoy a good dino-book like no other, and Indiana’s Life of the Past series… oh, wait. Probably the most surprising thing about The Sauropod Dinosaurs is that it was not published by Indiana University Press as part of their Life of the Past series, but instead by Johns Hopkins University Press. For anyone familiar with the aforementioned series, this book would fit right in, and displays similarly high production values, gorgeous illustrations, and accessible popular science. I have yet to go beyond merely flicking through it and admiring it, but I could not resist and got myself a copy as soon as this came out.

The Arctic Guide: Wildlife of the Far North

The Arctic Guide is a fantastic reminder of the precious diversity of wildlife that occupies the Northern regions of the planet – including mammals, birds, fishes, lizards and frogs, flies, bees, butterflies and flora. There is even a fascinating entry on domesticated sled dogs. It is beautifully produced, as we have come to expect from Princeton University Press natural history lists. Well-designed colour plates are accompanied by unusually descriptive detail by author Sharon Chester, making this an enjoyable general read for naturalists as well as an essential companion for Arctic researchers or travellers.

Britain’s Treasure Islands: A Journey to the UK Overseas Territories

To research Britain’s Treasure Islands, and the TV series of the same name that was broadcast in 2016, Stewart McPherson travelled to each of the 16 remote islands and peninsulas across the globe that are under UK sovereignty.

The contrasts between the different territories are fascinating, some can be travelled to with relative ease (e.g. Gibraltar and the Falkland Islands), but others are nearly inaccessible and as a result have most wonderful wildlife – one of my favourite chapters describes the British Indian Ocean Territory, home of undisturbed coral reefs, and giant Coconut crabs.

This hefty book is full of adventure and natural history, with fold-out maps and countless photos, and just perfect for dipping into when it’s cold and windy outside.

Bushnell NatureView Binoculars

We all love the Bushnell NatureView Binoculars because they are bright, well balanced and really solid, without being heavy. They have a fantastic field of view for scanning the horizon and an excellent close focus distance so they are brilliant for insect work too. They are very well designed binoculars at a really affordable price.

Sapiens: A Brief History of Humankind

Sapiens is a very ambitious book, covering the entirety of human history while exploring what the future holds for our species. You will learn to admire, sympathise with and hate our species as Harari examines the key factors which lead to our success over other animals. Through Hariri’s use of creative metaphors, he successfully manages to answer some of the big questions which would otherwise be incomprehensible. I can’t wait to read his latest book Homo Deus, which further explores the future of our species; where we’re are headed and what challenges we will face.

Bushnell Trophy Cam Essential E2

Whilst carrying out research for my PhD studying chemical communication in the Eurasian beaver I recorded many hours of beaver responses to the scents of intruding neighbours using trail cameras. I also enjoyed taking them home to record animals in my garden and surrounding countryside. The Essential E2 is an affordable yet good quality trail camera that will give you an insight into the animals visiting your garden. It is surprising how many different animals and birds visit gardens without people knowing, although some leave a nice surprise of a dug-up lawn! A friend recently used a trail camera to investigate who was digging up their lawn – badgers looking for tasty leatherjackets!

Solitary Beehive

Cavity nesting bees make up around 30% of the solitary bees in the UK. These non-aggressive insects require dry, hollow tubes to make their nests and use natural materials, rather than wax, to construct the cells in which the larvae grow.

I bought this small wooden solitary beehive for my garden in an attempt to provide nesting space for these vital pollinators. It has been a great addition to the garden and within a month of installing it, several of the holes had been packed with leaves. This was really exciting to see and suggests that it was being used by local leafcutter bees.

The box is well made and has withstood the local Dartmoor weather (i.e. windy and wet much of the time) really well. The wood has weathered attractively over the year and the box still feels robust and sound. As a fruit and vegetable grower it is great to know that we are attracting pollinators to the garden.

Heavy-duty Badger Gate

One of our latest developments is a redesign of an existing product sold by us. Our new heavy-duty badger gates are made on site, welded by our own fully qualified TIG welder, ensuring quality workmanship and a finish we hope the customer is amazed by.
Currently, our competitors only use galvanised mild steel. This results in a cumbersome, awkward to use product. Ours, however, is lightweight but still gives the same strength and reusability, making it far easier to transport to the required area and reduce the strain required to set up a gated badger enclosure. Competitively price, this item should fulfil all your requirements and more, a must have for anyone working towards badger conservation.

Pond Net

Our new pond net frame has been designed and developed to make a more sustainably sourced, budget frame for everyone from young children up. Manufactured in house, it means that we are no longer reliant on external suppliers to fulfil orders, and therefore able to lower the cost to you, the customer. Also, not being shipped from the other side of the world makes it a greener, more sustainable product, reducing airmiles and making it more environmentally friendly. Lightweight, coming in at only 300g, it has two tactile foam handles, fitting very nicely into the hand.

Arboreal: A Collection of New Woodland Writing

In memory of Oliver Rackham, Little Toller’s Arboreal sets out to curate a journey through the managed and wilder woods of Britain, with some very insightful companions. The book is a perfect blend of collected nostalgia, fancies, facts and little fictions that each in turn highlights something of the wild wood within us. Authors, journalists, artists, poets and woodland custodians impart wisdom, wonder and hope; and each leaves their own mark on the mind with their input. This book is an immersive, beautiful, lyrical and poignant treat, let it take you into the woods, or better still, take it with you and head for the trees!
