The Pine marten was once a common animal in British woodlands, but they were driven to near extinction by habitat loss and hunting. Pine martens belong to the same family as otters and weasels, and have experienced such a dramatic decline that they are now Britain’s second-rarest carnivore after the Scottish wildcat. Recently, a major milestone for recovery of the species has been reached; 18 individuals have been released into the Forest of Dean. Between August and September this year, these individuals were trans located from healthy populations in Scotland, to Gloucestershire. Their reintroduction may be vital to preventing complete extinction in England, as well as benefiting the entire forest ecosystem.
Tiny patches of rich plant life can be found dotting the deserts of Peru, and burrowing birds may be responsible. Mounds of sand shoveled out by nest-digging burrowing owls and miner birds encourage more seedlings and exclusive plant varieties to grow compared to the undisturbed ground surrounding. Deserts are very hard places for seeds to germinate, not just for lack of moisture but for the crusty, cyanobacteria-covered soil that is commonly found. This crust is a problem for seeds because seeds stranded on top of the soil are exposed to the harsh conditions and the crust forms a barrier for water to reach the seeds below. Burrowing birds break through this tough barrier to build their nests, providing an area of sand and soil that water can pass through, allowing seeds to germinate.
For as long as there has been an Endangered Species act, the Kirtland’s warbler has required protection- until this year. The Fish and Wildlife Service (FWS) in the US announced on October 8th that it is removing the Kirtland’s warbler off the endangered species list after active management over the past 50 years. FWS cited the work done by Michigan state and federal agencies to boost breeding habitats and combat brood parasitism. Although, they are no longer classified as endangered, the Endangered Species Act notes that they remain a ‘conservation-reliant species’ in order to maintain their success in the future.
Deep beneath the surface of the north Pacific ocean lives the warty Pacific octopus, a rather cute, pink and warty creature that wanders the seafloor. Scientists have been studying how the appearance of this octopuses changes with depth and have made some interesting discoveries. Using a manned submersible vehicle, ALVIN, researchers from the Field Museum, Chicago, took 50 specimens from depths ranging from 3,660 to 9,000 feet below the surface of the Northeast Pacific, along with other donated specimens. Despite the octopuses looking very different to one another it was discovered, through DNA analysis that they were all warty pacific octopuses.
As I walked across the Wembury beach car park something caught my eye, a small brown leaf blustered and bumped across the tarmac, battered by the fierce wind. As I focused, I realised it wasn’t a leaf, it was a butterfly! I caught up with the little insect that had temporarily come to halt, and I saw that it was a somewhat ragged looking small copper. Soon it was caught by the wind again and somersaulted unceremoniously onward across the car park.
Minutes later I found myself at the data collection point at Wembury Marine Centre. “Have you got small copper butterfly yet?”, I asked. “Not yet”, came the reply “Not many butterflies have been found in this weather!”
The butterfly was faithfully noted down, just like all species would be over the next 48hrs. For this was Wembury BioBlitz 2019.
You may recall that a BioBlitz is a coming together of professionals and a whole host of other interested parties, from school groups to amateur naturalists. The goal is to engage in a period of intense biological survey in order to record as many species that exist within a particular location as possible. As advertised by Emily Price and her interview with Nicholas Helm in a recent NHBS blog, the Wembury Bioblitz 2019 took place on September 27th and 28th and NHBS had been invited to attend.
This was the 10th Anniversary of the first Wembury BioBlitz and also the 25th Anniversary of the Wembury Marine Centre. An extra special occasion for the partnership of organisations that came together to organise the event especially the Devon Wildlife Trust, Marine Biological Association and the National Trust.
Wembury boasts a spectacular stretch of South Devon coastline which is renowned for supporting a rich diversity of wildlife and as such is designated an Area of Outstanding Natural Beauty, and a Voluntary Marine Conservation Area, so it is an great place for a Bioblitz!
On the morning of Friday 27th September the BioBlitz began and a host of organisers, volunteers and stall holders gathered to start the day’s proceedings, the BBC were there too, filming for Countryfile (the story goes out on October 13th). The weather did not look promising with driving rain and an unrepentant wind threatening to lower everyone’s spirits. However, everyone pressed on unperturbed with great enthusiasm and as the first eager local primary school groups arrived the day was up and running!
NHBS was there to set up a stall of useful equipment and books such as invaluable field and FSC guides which, like the other stalls, was soon inundated with excited school children. They were particularly impressed with our loan out of hand lenses which were immediately to put to good use! Others gathered around tables that gave the opportunity to peer down microscopes at a range of marine organisms or handle a whale’s rib or a dolphin’s skull!
The BioBlitz included a series of surveys across the key habitats that the Wembury locale offers including, of course; the rocky and sandy parts of the shore, but also ancient woodland, a stream, meadow, the coastal path and cliffs and parkland. Experts led parties out into the blustery conditions to scrutinise these zones and gather as much data as they could.
Down on the beach, my colleague Hattie had fun with a nice little gadget called a Video Endoscope to take pictures of rock pool life.
Back in the base camp Marquee, we soon discovered that we could contribute to the data collection ourselves as a host of crane flies, rove beetles, pill lice, spiders and earwigs began to explore the stall! News of rock pool discoveries reached us too, including brittle and cushion stars, snake locks anemones, gobies and five bearded rocklings!
By mid-afternoon the school groups had departed and it was time to pack up for the day, although for some there were many more hours of computer data entry and even nocturnal surveys ahead.
The following day the weather conditions initially seemed to have calmed and even the sun made an appearance! We were ready for Day 2. During the night, moth and bat surveys had taken place to boost the figures, but word came through that the overnight species count was a somewhat lowly 120 and a big push was needed if the target of 1000 species was to be achieved. With no school parties around to help this time, this was a day for families to get involved and once again the surveys commenced.
By 3.30 that afternoon, just as the weather vehemently turned for the worse again, it was time to call a halt to the BioBlitz and everyone began to gather for prize giving, species total announcements and chocolate cake in the shelter of the Marine Centre.
At the time of writing this blog, 840 species made the list for the 10th Anniversary BioBlitz a figure which is comparable to the number of species found in 2009.
Taking part in a BioBlitz is a fantastic way to engage in citizen science. They are great fun but are also a brilliant way to collect important data that can be used to gauge how our local biodiversity is coping with all kinds of environmental pressure including climate change and habitat loss. If you get the chance to get involved in one, I urge that you do so ……. and just ignore the weather!
Edit: We’ve received some highlight findings from the events organisers:
2x Giant Gobies were found during the night time rockpool safari
Many sightings of a bird called the Cirl Bunting, a once rare species that is now on the up near Wembury!
Many of us delight at butterflies visiting the flowers in our gardens, be it the drunken admirals of autumn or the spritely orange-tips in spring, yet some of us still seem to shudder at the thought of dingy moths bothering our windows at night or worse still munching our clothes to dust in our cupboards. In the middle of June, armed with two moth traps and a couple of trusted field guides, I attended an open garden in Somerset ready to join the #Mothsmatter conversation initiated by Butterfly Conservation to dispel the moth myths and encourage a fascination for these insects.
Setting up a Skinner moth trap in a covered porch over a couple of cold nights, I wasn’t entirely sure what species would be flying, but sure enough in the morning as I lifted the lid and slid the egg boxes out, there were some delightful species to see. Visitors in the garden were suffice to say, in awe of the moths the light brought in; the Poplar Hawk-moth and the Eyed Hawk- moth, the Fox Moth with his rabbit ear antennae and the remarkable Buff-tip.
We are becoming well aware that UK moths are in decline with an overall decrease in numbers by 28% since 1968, and over 60 species becoming extinct in the 20th century. Moths are a key indicator of environmental health and, as vital as they are to other creatures as a food source (their declines are impacting on breeding birds and bats) they are also vital for the pollination of native flora, an essential element to the tapestry of wild life. There is also evidence to suggest that climate change is shifting the habitable ranges of many of the moths that call the UK home, and while this can produce some spectacular species visiting from continental Europe, many of the species that have relied on the temperate climate in the UK are being forced out northward.
With a recent trend in wildlife gardening and more strict rules on chemicals used in agriculture, there is hope however that we can retain and rebuild some of the moth populations that are so vital in our countryside. Butterfly Conservation have a wealth of information available on their website about the trends of moth populations and, very importantly, what you can do to take action, join the conversation and promote moths at https://butterfly-conservation.org/moths/why-moths-matter
If you are interested in learning about which moth species are visiting your garden or local wild places, light trapping is simple and loads of fun. At NHBS we supply a range of moth traps suited for a number of habitats and a wide selection of amazing field guides to aid in identifying the moths you find. Below we have listed some of our favourite traps and provided a little more information on the differences between them, however if you wish to see our full selection of moth traps please visit our website.
Robinson Moth Traps
These large traps are renowned among lepidopterists because they offer the highest attraction and retention rates available. These traps are fitted with either mercury vapour or actinic electrics. Mercury vapour bulbs offer greater brightness than actinic bulbs and consequently they will often attract more moths. However actinic electrics may be favourable in areas where the brighter bulbs may cause disturbance; they also run cold and do not need to be shielded from rain, unlike mercury bulbs which are likely to shatter when used without a rain guard.
These traps are precursors to the Robinson, and as well as being a more economic choice, they allow the catch to be accessed while the trap is running. They feature a plastic or wooden box with a light fitted to a cross member above a long slit through which moths fall and become trapped. A highlight of this box are the transparent panels that make up the trap lid. These can be removed to access the catch while the trap is running, which is great for real-time surveys and demonstrations. These traps can be easily collapsed down for easy storage and transport.
Compact 20W Skinner Moth Trap (240V)
* Price: £179.00 inc VAT
* Dimensions: 32 (h) x 35 (w) x 35 (d) cm
* Weight: 3kg
* Electrics: 240V mains electric

Heath Moth Traps
These traps are favoured for their lower cost and compact design which makes them highly portable (excellent for use in remote areas) and easy to store; some are even small enough to fit into a rucksack. They are usually battery powered and feature a low wattage light source of between 6 and 20 Watts (however some mains operated traps can reach 40 Watts), and consequently these traps have lower catch sizes and retention rates than Skinner or Robinson models.

Although we are all familiar with the important role that bumblebees and honeybees play in pollination, over 90% of the UK’s 267 bee species are in fact solitary bees. Pollinating animals are responsible for one third of the food we consume and solitary bees are particularly efficient pollinators. Unlike other bees solitary bees do not have pollen baskets and so transfer much more pollen between flowers, meaning a single red mason bee provides a pollination service equivalent to 120 worker honey bees. This makes them a critical resource in our gardens and wider countryside and one that we should all be keen to protect. We have collated some information below on how to help encourage and preserve these fascinating creatures.
Solitary Bee Ecology
Solitary bees use a wide range of nest sites including tunnels in wood or mortar, plant stems and even snail shells. They lay eggs in a series of cells and then block the entrance with materials such as mud, leaves or fine hair. The female lays an egg with a food source, made from pollen and nectar, before building a partition wall and moving on to the next cell. The bee larvae hatch, eat the food source then overwinter as a cocoon before emerging the following summer as adults.
There have been extremely worrying declines in insect numbers recorded across Europe, and solitary bees are no exception. The increased use of chemicals in farming, loss of flower meadow food sources and loss of nest sites in hedgerows and gardens are all combining to drive down numbers. The good news is that it is easy to provide food sources and nesting habitat in your garden to help solitary bees and increase pollination.
Providing Resources for Solitary Bees
Provide food sources for solitary bees by planting wild flower seeds, native trees such as hawthorn and willow, bee friendly plants such as ivy, foxgloves and lavender and allowing plants such as borage and thistles to flower in your garden. Nest sites can be provided by leaving dead wood and stems standing, creating a patch of bare earth or mud bank for mining bees and by installing wild bee houses.
With careful design consideration, bee houses can provide shelter and nesting sites for solitary bees. Bee houses can be manufactured from a variety of materials but should have a good overhanging roof to protect the nesting tubes from rain, nesting holes between 2 and 10mm in diameter and a solid back. It is better to have a number of smaller bee houses, rather than one large house to reduce the risk of parasites finding the nest. Alternatively we have a wide range of solitary bee nesting habitats available on our website.
You can tell which species of bee is using your bee house by examining the material used to plug the entrance hole. Different species also emerge at different points in the year. The most common species likely to populate bee houses are red mason bees who use mud and are active March – July, leafcutter bees who use leaves and are active May – September, and wool carder bees who use fine hairs and are active June – August. Please note that there are fewer solitary bee species in the North of England and Scotland.
Solitary Bee House Siting and Maintenance
Insect houses should be sited at least 1m off the ground, facing south or south-east, with no vegetation covering the entrance and in full sun as insects need warmth to keep moving. They should be firmly fixed so that they don’t move in the wind. If your box is likely to be occupied by red mason bees then it is helpful to ensure that there is a patch of damp mud nearby. In order to maximise the chances of adults emerging successfully from the cocoons, it is a good idea to bring bee boxes indoors into an unheated shed or garage during the winter to avoid them getting too damp. The boxes should then be taken back outside in March in time for the new adults to emerge. There is some debate as to whether brick / concrete boxes should be cleaned but they can be cleaned out with a tent peg and pipe cleaner. Boxes with cardboard tubes should have the tubes replaced regularly. Keep an eye out for failed nests and tiny holes in the mud entrance as this can indicate that the nest tube has been taken over by parasites.

Earlier this year we were delighted to launch another exciting product manufactured here at our base in Devon. After a concerted period of design and manufacturing effort by our expert Workshop Team, followed by testing and review by ecological professionals, our NHBS Harp Trap was ready for production. The launch of our product into the wildlife equipment market signals the arrival of the only commercially produced harp trap in Europe.
What is a Harp Trap?
A harp trap provides an alternative bat survey method to mist netting or the use of bat detectors. They are particularly useful in situations where bats in flight can be channeled through a natural funnel such as above a water course, a cave or mine entrance or a clear area within a forest.
Harp traps consist of a frame which is either freestanding or suspended, and supports two to four rows of nylon strings. The bats will fly into the nylon strands and then fall unharmed down into a collecting bag below. The catch bag is made from green cotton canvas that is water resistant and breathable and includes heavy duty clear plastic baffles to prevent the bats from escaping. Unlike mist nets, harp traps do not entangle the bats an it has been reported that they can be more effective for surveying bats, potentially capturing higher numbers of individuals.
The NHBS Harp Trap
The new NHBS Harp Trap is a three-bank trap, meaning it has three rows of nylon line. Our trap has a catch area of approximately 4m2 and catch bag which is around 60cm deep. It folds down neatly into a bespoke carry bag and weighs approximately 15kg-full specifications and dimensions are below. The trap takes two people around 10 minutes to assemble and stands on four sturdy, extendable legs and which can be arranged at the height that you need the trap to be. There is also the option to anchor the harp trap with guy ropes in windy conditions. The trap can also be adapted to be suspended if this is required.
Our trap has a few innovative features designed to make assembly and disassembly easier. Firstly the strings are wrapped around a winding mechanism which greatly reduces the stress and time-consuming act of sorting through tangled lines in the dark.
There is also an extension under the catch bag, which prevents the bats from flying underneath the trap and this doubles as protection for the component parts as it wraps around the disassembled trap when it is stored in its bag.
Catch area: 4m2 approximately Catch area L x W: 180 x 225cm Length: 180cm Catch bag depth: 60cm Catch bag width: 44cm Weight: 15kg
Operational dimensions With legs fully retracted: Height 314cm Width (at base): 62cm
Length (at base): 230cm With legs fully extended:
Width (at base): 100cm
Length (at base): 252cm
As our harp trap evolved, prototypes were trialed and reviewed by ecology professionals; Professor Fiona Mathews of Sussex University and Neil Middleton of Batability. Their expertise and excellent feedback helped us develop our the harp trap to the point that it was now ready to go live.
The team at NHBS have done an excellent job in coming up with a new and refreshing approach to harp trapping, which shows many innovative and useful design features. When testing the equipment we were able to demonstrate that it was quicker/easier to assemble than competitor’s products. We are happy to recommend this harp trap, and will be ordering one ourselves, to be used during our training courses and for bat-related research.

For 30 days wild this year we decided to take part in as many random acts of wildness as we could. From bug hunting to rock pooling, lichen identification and more, read on to discover ideas for summer activities you can take part in too!
NHBS Book specialist, Nigel took some time out to go bug hunting with his children, their favourite find being a Red Admiral. They enjoyed using our Educational Bug Hunting Kit.
NHBS EQ Specialist, Johnny took out some sound recording gear including the Tascam DR05 to record Common Cuckoos on Dartmoor. Read more about this on our sound recording blog.
Rock pooling in Plymouth was the next activity with our Marketing Coordinator Soma and British Wildlife Editorial Assistant Kat. Using our NHBS Rock Pooling Kits we found a sea spider (pycnogonid) and a Netted Dog Whelk among lots of seaweed. We also collected some seaweed to press – see part 2 for the big reveal!
The European Badger (Meles meles) is one of the most iconic species found on the British Isles. These shy and elusive animals spend much of their time during the day hidden away within their extensive underground setts, emerging around dusk to forage on smaller mammals, earthworms, roots, bulbs and fruit.
Within their territories, badgers will follow established routes between foraging areas. When these pathways become obstructed by fencing, such as exclusion fencing for stock or deer, badgers will often dig under the obstruction to regain access to a familiar site and in doing so they may cause damage to the fence and allow in potentially unwanted species. In these circumstances, many developers will install a badger gate to allow badgers to freely access the site. These rectangular gates are constructed of either wood or metal and often feature locking mechanisms to ensure badgers can only pass through in a certain direction.
Although badgers are protected under the Protection of Badgers Act 1992, there are situations where developers need to temporarily or permanently exclude badgers from areas. This may be when they, or their setts, could be at risk of harm or disturbance. In these circumstances, and under acquisition of a license, one-way badger gates can be installed in sett entrances or in fencing surrounding a development to gradually exclude badgers from the area. These badgers will then either relocate to a new territory or to a nearby artificially-created sett.
At NHBS we manufacture a range of badger gates and this article will outline how they can be installed and used in different badger mitigation projects.
Softwood Badger Gate
This softwood badger gate has been designed in accordance with the specifications outlined by Natural England (available here) and is an excellent economic choice for many projects. It is constructed from untreated FSC-certified timber, which ensures badgers will not be harmed if they ingest any chewed wood. This gate has been designed so that it will not jam following periods of rain when the wood may swell.
The softwood gate is suitable for use where badgers require access through a fence. This gate can also be used in exclusion projects; however unlike our aluminium gates they can be damaged by chewing and often have a shorter lifespan.
Price: £25.99 inc VAT £27.95
Frame Dimensions: 450mm (H) x 285mm (W)
Entrance Dimensions: 250mm (H) x 200mm (W)
Material: Untreated FSC timber
Access Badger Gate
The access badger gate is constructed from marine grade aluminium which ensures it is strong enough for repeated use while keeping it lighter than most steel gates. It features a heavy-duty grill panel which allows badgers to view what is on the other side of the gate, which can encourage some badgers to pass through. It has pointed legs which should be driven into the ground using a wooden mallet, however a hammer can also be used with a block of wood (striking the frame directly may cause warping and damage). The gate has two locking tabs that can be adjusted using a size 10 spanner to allow either two-way or one-way access.
This gate is designed for use in long-term projects where badgers need access through stock or deer fencing. For exclusion projects we would recommend our exclusion gates.
Price: £73.50 inc VAT
Frame Dimensions: 595mm (H) x 295mm (W)
Entrance Dimensions: 320mm (H) x 220mm (W)
Material: Marine Grade Aluminium
Exclusion Badger Gate
The exclusion badger gate is also constructed from marine grade aluminium and comes fitted with a solid gate flap. This solid door has been designed based on evidence that some badgers can learn to use their claws to lift grill gates open. Another feature of this gate is that it does not have legs. This allows the gate to be positioned either vertically or horizontally in awkward sett entrances where a typical vertical gate would not be suitable. By installing this gate ecologists and developers can be confident that badgers will not be able to re-enter an exclusion zone.
This gate is also available with pointed legs, for installation within exclusion fencing.
Price: £73.50 inc VAT
Frame Dimensions: 400mm (H) x 295mm (W)
Entrance Dimensions: 320mm (H) x 220mm (W)
Material: Marine Grade Aluminium
All of our gates can be incorporated into this high tensile wire fencing. It can be erected as a freestanding barrier or installed across a sett to prevent badgers from digging to form new entrances or to get around any installed gates.
Price: £245 (50m)
Stainless Steel Cable Ties
These strong, corrosion resistant cable ties can be used to quickly and easily secure a badger gate frame to the surrounding fencing.
Price: £8.50 (pack of 20)
Caudon® High Tensile Steel Pegs
These steel pegs are excellent for securing fencing to the ground, particularly in areas where badgers are prone to tunneling. These pegs can also be driven through the access and exclusion badger gates to provide a firmer placement.
NHBS Equipment Specialist Johnny Mitchell, explains the ins and outs of acoustic recording in the field and highlights key equipment items to get you started.
In recent years advances in portable recording equipment have led to an increase in the exploration of listening as a method of engaging with as well as studying the natural world. This blog looks at a number of different equipment options across a range of budgets and objectives while briefly outlining some of the main technical considerations.
Equipment and Technical considerations
For those interested in having a go at sound recording a handheld recorder is a great starting point and Tascam have some great entry level options such as the DR-05 and DR-40 both of which allow you to record uncompressed audio. The advantage of this method is that the recorders are highly portable and require very little set up – invaluable if you’re out and need something that can be used at a moments notice.
The built-in microphones will not compete with a professional external microphone and if recording becomes more than a passing interest dedicated microphones can be a great way to optimise your setup for specific recordings. We cover a few of the microphones in our range below with a quick guide to their application. The right recorder should have a logical menu system and inputs that allow for a suitable upgrade path via the connection of external microphones.
I personally enjoy the use of stereo microphones for capturing the ambience of entire soundscapes. The Rode NT4 Stereo Microphone or Audio Technica AT8022 X/Y Stereo Microphoneare both great options for this, which contain two microphone capsules in a portable housing. Both models are examples of condenser microphones which will require external power to function. To provide this, look for a recorder that has XLR inputs and an option to turn on phantom power; the Tascam Dr-40 would be a suitable choice in this instance.
There are also several options designed exclusively for use in the field. A common type makes use of a parabolic dish, effectively acting as a kind of audio zoom lens making them useful for focusing in on a particular sound-source. Some of these systems require a different type of power known as plug-in power so you’ll need a recorder able to supply this via a 3.5mm mic/line input as found on the Tascam DR-05.
The Hi-sound and Telinga PRO-X systems are good examples of plug-in powered parabolic systems. If your recorder does not have plug-in power, you can use an XLR to PiP adaptor. This connects to the XLR outputs on your recorder and converts the phantom power produced by the recorder to plug-in power which can run the microphone.
Finally, we feature static recording devices such as the SM4 Acoustic from Wildlife Acoustics and the Bar-LT from Frontier Labs. These waterproof units feature built in omni-directional microphones and can be secured to any suitable surface. The long deployment times and scheduling functions make these ideal for long-term bioacoustic studies.
In the field
To test a small cross section of equipment, I headed to a small forest within the Dartmoor National Park to capture the distinctive call of the Common Cuckoo, armed with a Tascam DR-40, XLR to PiP adaptor, Hi-Sound Stereo Parabolic system and a Wildlife Acoustics SM4 Acoustic recorder.
I initially walked a narrow path that cut through a steep section of woodland, at this point the cuckoos could be heard faintly calling from lower down in the valley. Locating a suitable tree easily accessible from the path, I decided to deploy the SM4. The SM4 has been designed to be exceptionally quick to set up straight out of the box and for this field test, I set it to ‘always record’ and secured it in place with a Python Mini Cable Lock.
Static recorder in place, I then used the Tascam DR-40 whilst walking through the woodlands to capture the changing soundscapes as I moved away from the sound of the river and closer to the open moor.
The DR-40 has a clear front facing screen that is easy to read in all light levels, pressing the record button once arms the unit allowing you to see and hear the recording levels. A good pair of headphones is recommended for use with this unit as they are susceptible to a certain amount of handling noise.
I then connected the parabolic to the Hi-Sound parabolic to the Tascam using the XLR to PiP adapter.
Dropping off the path I headed towards the middle of the wood where the Cuckoos could be heard calling in the distance. The high directionality of the parabolic microphone was excellent allowing me to pick out individuals among the woodland birds present.
Late in the evening whilst preparing to pack up I was rewarded with a fantastic display as several cuckoos alighted on the trees around me, a recording of which is included below.
I highly recommend getting out and exploring natural soundscapes in your local area, especially at this time of year. As with any piece of equipment it takes a few trips to really get a feel of what they’re capable of, but any one of these items could become a reliable piece of gear for your sonic explorations.

Sometimes the most extraordinary nature stories and scientific revelations lie in plain sight. So familiar that unique stories of survival are overlooked. Rock Pool is an eye-opening, enchanting journey into the miniature worlds of rock pools with a new author who will change the way you view even the most ordinary creatures – from crabs to barnacles, blennies to anemones – forever.
Educator and award-winning blogger, Heather Buttivant kindly took some time out of her rock pooling schedule to answer our questions about her new book.
Your passion for the marine environment shines throughout Rock Pool, where did your passion stem from?
Like most children growing up by the sea, I liked to pick up seashells, but for me it became an obsession. Back then I couldn’t name everything, but the variety of shapes and textures and the vibrant colours fascinated me. The longer I looked into rock pools, the further I was reeled in. It’s a passion I have no intention of out-growing: no matter how much I know, there is always more to learn.
What was the original inspiration behind your book?
It has always seemed a shame to me that there is so little nature writing available about our incredible intertidal wildlife. When I created a website as part of my MA in professional writing with Falmouth University, I struggled to imagine why anyone would be interested in my ideas for a novel, but the thought of opening up the little-known world of the rock pools filled me with excitement. My Cornish Rock Pools site took off faster than I expected and when the site won the BBC Wildlife Magazine Blog of the Year Award, it came to the attention of the lovely people at September Publishing and this was the perfect opportunity to bring my love for nature writing and for seashore together as a book.
You’ve selected a fascinating range of marine creatures; how did you choose them from such a biodiverse environment?
My identification guides to the seashore contain thousands of species, so narrowing this down to just 24 animals felt like a near-impossible task. Most of the animals I’ve selected can be found all around the UK and Ireland and together they tell an incredible story of survival. I have aimed to convey the experience of animals living in different zones of the shore and in the range of different environments from mud-flats to seagrass beds. Some of the creatures, like barnacles and limpets, are familiar yet have remarkable abilities that are unimaginable to us land-dwellers. Others, like corals, sharks and cephalopods, are animals that most people assume can only be seen by divers but with luck and perseverance they may be seen by rock poolers too.
Rock Pool is full of exciting encounters you have had at the seashore, but which was your most surprising?
I find something new almost every time I visit the shore, but one day, whilst dangling my feet in a pool, with all my attention focused on a tiny sea slug in a petri dish on the rock beside me, I noticed movement in the water. When I glanced down I realised that a substantial lobster was inching towards my toes! I nearly dropped my camera. ‘Bob’, as I now know him, has become quite a legend in our family and his location is a secret that is closely guarded by all those who have met him.
Do you have any tips for a successful rock pooling session?
My top tip is to join a rock pooling event where you can learn and explore with the experts. This is a great way to see amazing animals and to find out how to keep yourself and the wildlife safe on the shore. The key to spotting creatures is to slow right down and take the time to look closely at the small things. Most rock pool animals are masters at hiding in plain sight. A single rock may be densely packed with keel worms, sea squirts, sponges and crustaceans, but at a quick glance you’d think there was nothing there. Always check the tide times first and leave everything as you found it – gently replacing stones the right way up.
Finally, do you plan to write any more books in the future?
Our rock pools are so incredibly diverse that I might never run out of material for more books. However, I’m also passionate about the importance of giving people, especially children, better opportunities to connect with the natural world. We protect and care about the things that we love, so it’s vital that we all feel that we are a part of the ecosystems on which we depend. Perhaps that will be my next writing project?

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!
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!
