Wilder Sensing: An Interview with Geoff Carss

Wilder Sensing, founded in 2021, is bringing innovative techniques to conservation, providing additional insights into biodiversity. This promising tech start-up featured on Springwatch this Wednesday (12th June), showcasing the applications of this innovation. We had the opportunity to chat with Geoff Carss, CEO of Wilder Sensing, on the organisation, its role in conservation and the future of technology in the field.


Can you share with us why Wilder Sensing was founded and what the company is involved in? 

Wilder Sensing was founded to ensure that anyone can collect high-quality, long-term biodiversity data. There are many different ways of doing this, but we focus on sound. By recording 24/7 for weeks, or even months, you can build up a very rich picture of what is present in an environment. The technology we use is low-cost with limited bias, and it is easy to use, even for non-professionals. It’s not perfect, especially because we are focusing on birds at the moment. Not all birds make much noise – some make very subtle noises which we can’t pick up – but for most species it works well. 

Can you tell us about the capabilities of Wilder Sensing technology and the insights that it can provide for a given environment?

We work with our customers to agree on survey patterns and how many recorders should be deployed on each site. The customer uploads their audio files to our website, and once they have arrived, we automatically process them using machine learning. It takes us around 20 seconds to process an hour-long file, and we can process many in parallel. During this, the technology checks every three seconds to see if a sound has been detected – every sound gets a species match, and a probability is assigned. So, for instance, the technology will be 92% certain that it has detected a Robin. Through this, we can give a species richness assessment, which is a species list at the moment. Our technology is currently unable to tell us how many individuals there are in a given space – there could be one very noisy bird, or ten very quiet ones.   

However, bioacoustic surveying technology does not remove the need for ground truthing. It is still important to get the baseline. Ecologists will find species that we don’t pick up. And the converse is true as well. We can find 20-30% more species when combining acoustic and traditional surveys. We are also working on other approaches for the future, like triangulation, which could identify exactly where a sound is coming from.

We’re involved with a whole raft of different projects. We are working with environmental consultancies, Wildlife Trusts and NGO’s using acoustic technology for long-term surveying. Wendling Beck in Norfolk is a site that we have been working on for around 18 months. We realised that Skylarks are using one small part of the site, but you don’t see this until you look at the data – when you are just walking around, you don’t make that connection. If you look at some species, you might think that you have a ubiquitous habitat, but when you start looking at the distribution of birds and their calls, you may find that there are many times more calls in one part of the site. If you were to redevelop an area, you would probably lose some species altogether, but going into a development project, knowing that’s a likely ecological consequence, is really important and that is why acoustic technology is so valuable. 

What is the future for AI in conservation? Where do you think its applications could take us over the coming years??

I think it has a lot to contribute. To get good, accurate data you need highly skilled ecologists, people that really understand bird sound – it takes years to build those skills. I think the role will change so that ecologists will get more involved in survey design and interpreting the data to understand the consequences of a project. It becomes much more evidence-based and more quantitative. We have some customers who deploy up to 20 recorders, and you can get a quarter of a million acoustic records on each device. With that amount of data, you can start to ask different questions and we can see all kinds of behaviours that we couldn’t see before.   

In the South-west, some farmland was purchased to develop into allotments and after digging, they found that Skylarks were nesting on-site. Biodiversity Net Gain (BNG) does not look at species, so a habitat survey would not record Skylarks in the area. If acoustic recorders had been deployed on site, ecologists would know they were present – so well-rounded data will also help developers plan better, mitigating issues from the onset of construction. The BNG survey was designed to be consistent and relatively easy to use, and species surveys could prove to be more difficult because of inconsistencies and methodologies etc. With AI we can move to a new level of understanding. If you just stick the recorder out, it is consistent in how it works and removes bias.

For those interested in bioacoustics, it is worth noting that you will be holding webinars from July. What can we expect from these sessions?  

We have three sessions lined up. The first one is on 7th July and is about measuring nature using sound. It’ll dig into both how the technology works and how it compares against other methods, and hopefully we’ll have an open discussion around its strengths and weaknesses. The session is intended for people who are interested in the subject, and we will go through some examples. 

This will be followed by two in the autumn, which are more technical and are perhaps more suited to professional ecologists. These sessions will be touching on some of the technology behind Wilder Sensing and some of the ways it should and shouldn’t be used.

What is Wilder Sensing hoping to achieve over the next decade?  

I am hoping to move onto other taxa, the obvious ones being insects and bats. We would also like to look at triangulation as well – if we can triangulate how birds and bats are using a landscape, we can use this to help inform better environmental management. I think this data will be used with other environmental data in the future. People doing nature restoration or project planning need to understand the water quality, air quality, the climate etc. to get a better environmental outcome. And even forward-looking companies, we can look at their supply chain as well.

Increasingly the media are reporting on the quietening of British soundscapes, a symptom of the biodiversity and climate crisis we are facing. How do you think Wilder Sensing will adapt to an increasingly quiet environment? Will technology need to adapt to keep up?  

Wilder Sensing technology will quantify exactly what is happening in the biodiversity crisis. I have a copy of the iconic Silent Spring by Rachel Carson, which was published 60 years ago, and we haven’t learned from that. I think this type of technology will hold a mirror up to people to show exactly what is going on. I would love to get a good quality recording from 50 years ago, maybe two or three hours of dawn chorus in woodland, and go back to the same time of year in the same place (assuming it still exists) and compare it. Showing exactly that this is the difference in diversity.

No Mow May 2024: An Update

Each year, Plantlife launch their national campaign of #NoMowMay. This initiative encourages people across the UK to allow their garden lawns to grow wild in the spring, providing vital habitats for many species. Here at NHBS, this is our fourth year taking part – each year in awe of the diversity of species in our lawn. Find our previous No Mow May blog posts on our conservation hub. Here, we give an update on the species we saw throughout last month.  


The wilder lawns that develop during No Mow May provide a haven for invertebrate species in our gardens. At NHBS, we saw a whole host of insects in and around our lawn last month, from wasps to weevils and Green-veined White butterflies. Other highlights have included:  

A Small Yellow Underwing (Panemeria tenebrata) – a diurnal moth species frequenting meadows and grassland.  

 

Mayfly (Ephemera vulgata) – found near rivers and areas of freshwater between May and August.  

 

Volucella bombylans – a bumblebee-mimicking hoverfly common throughout the UK.  

 

Beautiful Demoiselle (Calopteryx virgo) – a damselfly with a striking blue, metallic body found near rivers and streams. 

 

And some beautiful wildflowers, including Red Clover (Trifolium pratense) and Perforate St John’s Wort (Hypericum perforatum). Here are some of our favourites: 

The Southern Marsh Orchid (Dactylorhiza praetermissa) – the most common and widespread of marsh orchids, features spectacular purple petals. 

 

Bee Orchid (Ophrys apifera) – named for its mimicry, the Bee Orchid self-pollinates due to a lack of appropriate pollinators in the UK. The specimen on our lawn has yet to bloom (left), but we have a striking image from last year showcasing the mimicry of this species (right).  

 

Cuckooflower (Cardamine pratensis) – also known as ‘Lady’s-smock’, this flower is one of the first signs of spring, often found near riverbanks, wet meadows and grassland. 

 

Germander Speedwell (Veronica chamaedrys) considered a ‘good luck charm’ for travellers, this plant has a beautiful blue flower and is found in meadows, woods and hedgerows across the UK. 

 

Our Product and Purchasing Manager, Mark, has documented the progress of his local park during No Mow May. Towards the end of the month, the green expanse had varying lengths of grass and plenty of wildflowers, encouraging pollinating species – a great example of how local councils can boost biodiversity in public spaces.  

 

And our Sales and Marketing Manager, Adam, has grown his lawn throughout May creating a corridor for local wildlife brimming with wild buttercups, dandelions and many other self-seeded plants.


No Mow May is a fantastic initiative to engage with, attracting homeowners, businesses and local councils with its wealth of benefits. If you have enjoyed taking part, then Let it Bloom June could be a great opportunity to continue supporting your garden wildlife. This scheme simply involves continuing the No Mow May philosophy throughout the summer with less garden maintenance. You may choose to allow your entire garden to grow wild or leave some areas untouched for wildlife.

South West Marine Ecosystems conference 2024

The 2024 South West Marine Ecosystems (SWME) conference was held at the Plymouth Marine Laboratory in April. Running since 2007, the conference brings together organisations and individuals involved in research on and management of the marine environment to report on annual system changes in the south-west. The conference covers the oceanography, plankton, seabed and seashore, fish, seabirds, seals and cetaceans of the south-west. Alongside key trends and interesting occurrences from the past year, SWME also encompasses management themes: marine planning, protected areas, fisheries, water quality and plastic pollution. This year’s theme focussed on the interconnectedness of the environment and its management, demonstrating this connectivity through interaction and discussion between guest speakers. In this blog we provide a roundup of SWME 2024

Environment 

The first session began with a rundown of oceanography and weather conditions across the UK, setting the scene for our marine environment. The UK experienced an increase in mean air temperature and increased sunshine duration over winter. There was also a decrease in mean rainfall across the UK and record-breaking heatwaves – some of us may remember the scorching temperatures of June last year, a worrying 2–3°C anomaly.  

From March 2024, a new bylaw prohibits the use of bottom towed gear in defined areas of 13 marine protected areas (MPAs). Hartland Point to Tintagel Marine Conservation Zone (MCZ), Cape Bank MCZ, Lands End and Cape Bank MCZ, South of Celtic Deep MCZ, Wight-Barfleur Reef MCZ, East of Haig Fras MCZ and Greater Haig Fras MCZ are the MPAs that will benefit from this designation in the south-west. Devon Wildlife Trust vocalised a desire for a ‘whole-site approach’ for MPAs in the region – managing the site in its entirety, not just where protected species or features are present.

The Devon Maritime Forum stressed an urgency to address issues surrounding water quality in the south-west. They reported that no single stretch of river was found to be in ‘good’ overall health in 2023 – with quality impacted by agricultural run-off, sewage overflows, climate change and urban diffuse pollution. The UK Government has pledged to invest £1.6 billion to improve the water quality of rivers, lakes and coastal waters. Investments will be used to tackle storm overflow discharges, treatment works pollution and water resilience. South West Water will also be investing £70 million to upgrade infrastructure to reduce discharges in the region.  

Analysis of plastic pollution showed that polyethylene was the most common material in plastic waste and marine litter fragments. To tackle the issue of plastic pollution on a global scale, the Global Plastics Treaty is under negotiation, and is expected to be legally binding by 2024. The treaty will address the full life cycle of plastic products and aim to end the pollution by these materials worldwide.  

Key points:  

  • Higher average winter temperatures and sunshine, with decreased rainfall were observed in 2023 
  • A new bylaw will prohibit the use of bottom-towed gear in seven MPAs. 
  • The UK Government has pledged to invest £1.6 billion to improve freshwater and coastal water quality 
  • The Global Plastics Treaty will be legally binding by the end of 2024, intending to end plastic pollution

 

Organisms

Plankton researchers saw a higher abundance of salps (a barrel-shaped pelagic tunicate), consistent with a general increase in filter feeders over the past 30 years. There was also an influx of Barrel Jellyfish strandings across the south-west, with the species accounting for 27% (467) of the annual total of jellyfish sightings. A new method of plankton sampling has been developed, called Automated In-situ Plankton Imaging and Classification System (APICS). This new technology will help to determine the impacts of environmental changes on plankton, allowing for long-term, broad-spectrum measurements of the group.  

New observations have improved our understanding of Basking Shark behaviour, revealing that this species may remain in UK waters throughout winter, instead of migrating south as previously believed. Blue Sharks were also caught more readily than previous years, exhibiting a higher catch per unit effort (CPUE), with over 1,000 caught off the coast of Looe, in Cornwall. The UK had its first sightings of Smalltooth Sand Tiger Shark, with a 10-foot individual washing up in Lyme Regis, Dorset. Typically seen in tropical and temperate waters, the discovery of this species in the UK is indicative of the effects of climate change on marine megafauna. Atlantic Bluefin Tuna have also been returning to the south-west with most sightings between July and February. There has been a marked increase in catch rate (over 5,000 were landed in 2023) which has prompted the introduction of fisheries plans (see below).

Rat eradication has been hugely successful for a number of seabirds. On Lundy, Manx Shearwaters and Puffins have responded positively and have seen population increases in 2023, and Storm Petrels have recolonised the island. Razorbills and Guillemots are also recovering well and are breeding successfully without predation from rats. The south-west has luckily missed the worst of avian influenza, although some small gulls and terns were affected in Dorset last summer. However, Kittiwakes are having local productivity issues which is prompting concern, and several species of gull are experiencing significant declines: Herring Gulls, Lesser Black-backed Gulls and Great Black-backed Gulls have all experienced losses over 40%. The English Seabird Conservation and Recovery Pathway (ESCaRP) report was published at the start of 2024, highlighting the sensitivity of seabird species to a range of pressures. Vulnerability assessments were conducted to inform the recovery pathway, and the report has made recommendations for conservation measures to address negative impacts.

There are concerns over the impacts of climate change on Humpback Whales. Increasingly, we are seeing individuals which are choosing not to migrate and are instead remaining in UK waters. Researchers believe that these animals are not undertaking seasonal movements due to a lack of food resources during winter – demonstrating that decreased productivity at the base of the food chain can cause issues further down the line for other marine organisms.

Key points:

  • New technology will provide a greater understanding of the impact environmental change may have on plankton 
  • Atlantic Bluefin Tuna and shark sightings have increased in the south-west, including the Smalltooth Sand Tiger Shark, never previously recorded in the UK 
  • Rat eradication programmes have been hugely successful in protecting seabirds 
  • Kittiwakes and a number of gull species are experiencing declines 
  • Climate change is thought to be impacting Humpback Whale migration 

 

Industry

The Crown Estate have announced plans to develop more offshore wind farm projects, generating an additional 4GW of electricity to contribute to the 50GW by 2030 goal. This additional capacity could power up to four million homes, contributing to the UK target of net zero by 2050. Large, floating platforms have been proposed to enable deployment in deeper water – installation further offshore provides more reliable wind resources, generating more power for the same installation on-shore. There have been assessments to prepare for the deployment of extensive offshore wind in the south-west – with pre-consent surveys run by The Crown Estate. Celtic Sea Power, owned by Cornwall Council, is supporting offshore roll-out and has identified areas for data collection in the region. There are three project development areas where aerial, geophysical, acoustic and LiDAR surveys are taking place to improve data collection, accelerating the programme. The Poseidon Project was established by Natural England to provide a sensitivity map across the EEZ (exclusive economic zone –a surrounding area of 200 nautical miles offshore, where the nation has jurisdiction over resources) through digital aerial surveys. Collecting detailed information on seabirds, marine mammals and habitats, the project aims to improve models of abundance and distribution for key species which may be impacted by offshore development.

Sardine and Anchovy stocks are reported to have had a good year, continuing to support fisheries in the south-west, while Sprat fisheries have slowed due to insufficient stock size and 0-group fish (fish in their first year of life). We can see that new fisheries are emerging in the region (e.g. Atlantic Bluefin Tuna quota of 39 tonnes), while other, more traditional stocks are declining (e.g. Edible Crab). Five fisheries management plans have been developed for bass, King Scallops, crab and lobster, whelk and non-quota demersal species – these plans are put in place to deliver sustainable fisheries while minimising negative impacts on marine species. Dogger bank SAC, The Canyons MCZ and Inner Dowsing, Race Bank and North Ridge SAC were protected from damaging fishing activity in 2022 by prohibiting trawls, seines, dredges and bottom towed gear – this bylaw seeks to protect cold-water coral reefs, seabed, sandbanks and biogenic reef.  

Key points:  

  • Offshore wind development is being accelerated by better data collection and availability, supporting the UK in reaching renewable energy targets 
  • Some traditional stocks are declining, while new fisheries are emerging 
  • Five fisheries management plans were introduced 
  • Four areas of conservation concern were protected to prohibit bottom towed gear 

This year’s conference was an enlightening insight into the marine ecosystem in the south-west and highlighted some inspirational conservation work undertaken by several organisations, and individuals, dedicated to this environment. The SWME YouTube channel has a selection of webinars and further information on the conference can be found on the SWME website 

The biodegradable dormouse tube trial

The dormouse nest tube problem

At NHBS, the environmental impact of our products, both in terms of their manufacture and eventual disposal, is at the heart of our manufacturing business. Of equal importance is the practicality of their design and how fit for purpose they are for their users. With this in mind, we are always looking for ways to both design new and improve existing products based on current research and feedback from our customers.

Last year, we began to apply this thinking to our dormouse nest tubes. We had some concerns about any tubes that might be left behind at survey sites, thus polluting woodlands with unwanted plastic. We were also thinking ahead to the disposal of tubes that, following years of use outside, are no longer fit for purpose and which must then be thrown away.

With this in mind, our manufacturing team began developing an alternative, biodegradable version of our dormouse nest tubes.

The current plastic dormouse nest tube
A new environmentally friendly design

Dormouse tubes consist of a plastic sleeve into which slides a wooden tray that also serves to seal one end when in place. These tubes create a dark and narrow enclosure that is ideal for dormice to build their nests. By strapping a number of these tubes to horizontal branches in a suitable woodland, they can be used to determine the presence of dormice by periodically inspecting them for evidence of nests and/or inhabitants. As this is a standard survey technique within the UK, our new, environmentally friendly dormouse tubes would need to be able to be used in the same way.

Our new design would use the same wooden inserts in combination with a modified sleeve constructed from Earthboard. Earthboard is a plastic-free biodegradable material, often used to make tree guards. It is coated with a non-toxic water repellent coating which makes it suitable for use outside, lasting for up to two years before decomposing naturally. Critically, being plastic-free, Earthboard does not shed microplastics into the environment.

Its relatively slow breakdown means that Earthboard would be ideal for our purposes. It would last for more than a single survey season in the field and, if accidentally left outside, would decompose naturally over time. Any tubes that fell to the ground would take around 16-20 weeks to break down and, at the end of the season, they could be recycled in the same way as cardboard (although they are not suitable for home composting due to their relatively slow rate of natural decomposition).

In 2023, our manufacturing team produced a number of Earthboard sleeves that were compatible with our existing wooden inserts. These were sent to several of our customers and associates who kindly agreed to undertake some field tests during the 2023 survey season.

Initial field tests

At the end of the dormouse survey season, our field testers helpfully provided us with lots of feedback. Unfortunately, not all of it was good. While most were broadly positive about the intention of the product, there were some significant problems.

The most serious of these was that, after a short amount of time in the field, deterioration by the elements meant that the tube was no longer a good fit for the wooden insert. The top of the plastic tube became curved, thus creating a space into which light, draughts and moisture could enter, making the tubes much less desirable to dormice as a nesting location. Similarly, the relatively pale colour of the Earthboard meant that the interior was not as dark as that of the original plastic tubes, again making it less attractive to dormice.

After a period in the field the Earthboard tube proved a poor fit for the wooden insert and allowed light and draughts to enter the nesting space.

A further concern related to how dormouse tubes are generally used. It is typical for ecologists to collect all of their tubes at the end of the survey season and re-use them in subsequent years. It is unusual for tubes to be left in the field, unless they cannot be located for any reason. Equally, there is a cost factor involved. Although Earthboard is suitable for recycling with cardboard via kerbside waste collections, which makes their disposal preferable to traditional plastic tubes, the need to purchase new sleeves at the beginning of each season isn’t an attractive option for most ecologists.

So, what next?

Due to the lack of positive feedback, along with concerns about the practicalities and economics of these biodegradable dormouse tubes, we have decided not to continue with their development. Despite the fact that this particular project didn’t ultimately lead anywhere, however, we are incredibly proud of our continuing endeavours to improve our products and make sure they are as user friendly and environmentally responsible as possible.

We would like to thank everyone that was involved in field testing this product and taking the time to provide us with such valuable feedback. It is only through constant communication and cooperation with our valued customers that we can continue to design, manufacture and provide such high-quality products and support conservationists worldwide.

No Mow May: A Celebration of Wildflower Power

This spring, traditional British lawns are out. Throughout the month of May, Plantlife urges us to let our gardens be wild with #NoMowMay. This exciting initiative encourages us to embrace a wild lawn this spring, providing plants, invertebrates and other wildlife the opportunity to make our gardens a home. No Mow May could transform your green spaces into a colourful kaleidoscope of flowers you never knew were there. From buttercups to bee orchids, here at NHBS we have had an astonishing array of wildflowers in previous years, and we are hoping that this year will be the same!

Knowing when, and how, to mow your lawn to encourage wildflower growth and minimise grass domination can be confusing, and there is no ‘one size fits all’ answer to supporting native wildlife. In anticipation of May, we outline the important things to consider when maintaining your lawn over the coming seasons.


Tightly manicured garden lawns are unable to host the diverse communities associated with a natural space. The artificially constructed environment, with uniform grass length and limited species, prevents our native wildflowers from blooming and our vital insects from settling. Lawn feeds and fertilisers often used to maintain our lawns can result in unnaturally high levels of soil fertility. Such levels can unintentionally diminish the diversity of flora within our gardens, since native wildflowers are adapted to low-nutrient conditions. Associated with higher carbon emissions, time consumption and overall cost, many are steering clear of a high maintenance lawn this spring. 

A spring-flowering lawn provides a whole host of benefits for the wildlife within our gardens. Opting for a wild, native lawn provides essential breeding habitats, food sources and physical protection for a number of species. These spaces give wildflowers a chance to bloom and set seed, benefitting both insects, and the predators who rely on them.

So, how and when should we mow?   

Less is more! Switching up your mowing routine, or refraining from a mow in some areas, is a great way to maximise diversity in your garden. After a short time, your outdoor spaces can flourish into a haven for wildlife. From voles to vetches, and even British reptiles, watch your garden transform from monoculture to a wild refuge.  

Varied grass length, wild edges, or longer patches of lawn are great for attracting local wildlife to your garden. You may find orchids, ox-eye daisy and knapweed in these longer areas, which also provide cover for small mammals that may be wandering through, and shorter areas can boost pollen availability from low-lying flowers, like buttercups and clover. Plantlife advocates for a varied mowing approach with longer patches throughout the garden, alongside shorter areas (aiming to mimic grazing pressures of different herbivorous species in the wild). For instance, you might decide to maintain shorter pathways and areas around patios, but allow other areas of your green spaces to grow freely.  

It is important to remove cuttings after lawn maintenance to prevent excess nitrogen in the soil, thus reducing nitrophilic plants (species with a preference for nitrate rich habitat, typically from fertilisers and the decomposition of organic material) in your garden. ‘Cut and rot’ management can be counterproductive when cultivating wildflowers, as low levels of soil nutrition are preferred by many and will harbour the most diversity. In fact, frequent fertilisation and additional nutrition can result in an overall decline of wildflowers, leading to a dominance of nitrophilic plant species.

Knowing when, and how, to mow during the year is key to maximise flowering of wildflower species, while simultaneously preventing grass domination: to do this, it is generally recommended to mow three times a year; early spring, late summer and in autumn.  

A 3-inch, early spring mow is beneficial to kickstart the season, promoting early growth and blooming.  An early mow can also help to tackle nitrophiles, like nettles and cow parsley. This can help to prevent competition, allowing wildflowers to grow undisturbed. However, be wary of mowing too early, as this can prevent wildflower seeding and will impact your gardens growth next year.  

A summer mow in late July, or August, removes the previous growth, encouraging the bloom of wildflowers later in the season. As far as insects are concerned, the later the mow, the better. Insect species tend to hatch in the warmer parts of spring and summer, so a mow in late August will prevent harm to hatching individuals. 

Around late November, an autumn mow can help to promote reseeding and encourages germination in the following spring. Allow the wildflowers in your lawn to finish flowering and let them go to seed, a mow after this allows the seedheads to disperse seeds into your lawn. An autumn cut can also keep grass growth under control, further encouraging germination.  

There are also certain considerations to be wary of when forming wild areas in your garden. These habitats will attract a great number of species, who may make your lawn a home. Best practice involves leaving an area of your lawn untouched to house these species, but if you are looking to tidy up your garden after No Mow May, wildlife must be considered. Wildlife in our lawns can be harmed in the process of tidying up our outside spaces. It is recommended to disturb, or walk through patches to be maintained to shoo species from the area. On the first mow, start with a higher cut to give smaller animals a chance to escape. When mowing the lawn, start with garden paths and areas of high footfall, working toward the edges of the garden. This, again, provides wildlife with an escape route through the boundaries of your garden. If your garden has fences or hedgerows, a wildlife corridor along your borders is another way to support visiting animals. Untouched, or lightly managed, strips along these areas can provide a safe space for travel around the garden, providing cover and protection from predators.

How can we prepare for No Mow May?  

If you currently use fertilisers, lawn feed, moss killers or pesticides, abandoning the use of these additives in your garden will allow the soil to recover from these harmful chemicals. This can provide microscopic and invertebrate soil communities a chance to recover, improving the overall health of your soil.  

For some of us, early bloomers may already be present in our gardens. Cowslip, violets and primroses may be popping up on our lawns, showcasing the first few flowers of the season. You may consider allowing these to go undisturbed, giving them a head start for spring. Having said that, the best way to prepare for No Mow May is a 3-inch April cut to encourage a strong period of spring growth.  

Whether or not you decide to mow the lawn this spring, consider leaving an area of your garden wild. Whether this be a natural lawn or rough borders, we hope you feel inspired to take part in this year’s #NoMowMay! 

 

Q&A with Matt Larsen-Daw and Alana Scott: Celebrating 70 years of the Mammal Society

The Mammal Society, founded in 1954, is a UK charity formed to support evidence-based mammal conservation in Britain and Ireland. The Mammal Society is involved in promoting and enhancing conservation initiatives working to restore mammals and their habitats, with the overall mission of securing thriving populations of native species.   

The Mammal Society will be celebrating their 70th anniversary in 2024, which will be the focus of this year’s annual mammal conference. The conference will focus on the past challenges and successes of mammal conservation, and discuss opportunities for future work.  

Matt Larsen-Daw is the CEO of the Mammal Society. Having worked with WWF for some time leading education programmes, Matt is now working with the local mammal groups at the base of the Society’s work. Alana Scott works as communications officer for the Society, with a strong history in conservation biology and ecology. She also has significant achievements in the reintroduction of Water Voles in southern Cornwall.  

In anticipation of the upcoming National Mammal Week (22nd 28th April), we recently had the opportunity to talk with Matt and Alana about the successes of The Mammal Society, their upcoming 70th anniversary and goals for the future.

Firstly, could you give us a brief insight into how The Mammal Society came into existence back in 1954? 

Seventy years ago, in 1954, The Mammal Society was formed under the name of The Mammal Society of the British Isles (TMSBI), following a meeting of prominent zoologists, naturalists and the Zoological Society of London. The aim was to link amateurs and professionals in promoting the study of mammals, and by doing so to power conservation of mammals at a time when an alarming decline in the populations of several species was already being observed. 

Three years later the society started to deliver on its remit when it published its first book – A Field Guide to British Deer. Perhaps some well-thumbed 1st editions of this vintage text are still sitting on shelves? More likely readers may have one of the beautifully illustrated 4th edition copies of this handbook, published to coincide with another significant anniversary – the 60th year of the British Deer Society – in 2023. The British Deer Society is one of several organisations (including the Bat Conservation Trust and SeaWatch) that started their lives as subgroups within The Mammal Society, until their objectives became sufficiently ambitious and broad in scope to warrant a separate charity. This highlights one of the key roles that The Mammal Society has played over the past seven decades. By acting as a lightning rod for discussion and research around the big issues in mammal science and conservation, the Society has convened experts and enthusiasts to foster collaboration and initiate vital projects at all levels of mammal conservation. From collaborative research projects to species-focused organisations and grassroots local groups, the work of the Society has helped shape the mammal conservation sector we see today.  

What do you think has been the key to the enduring success of The Mammal Society? 

A key factor in the ongoing success of The Mammal Society is the community of mammal specialists and nature enthusiasts that has formed around it in the form of our members and local groups network. The staff team at the Society has never been big – in fact we are often assumed to be much bigger than we are, due to our vibrant social channels and the large influence we have on policy and practice. Our Council of Trustees, our Committees, and our ever-growing community of local mammal champions are just as important in the achievement of our aims. We are nothing without our members, and we hope that we give plenty back to those who join us in our mission to support and protect British mammals. Members receive our acclaimed seasonal magazine Mammal News, receive substantial discounts on our trainings and events, and have the opportunity to influence the priorities and projects of the Society. Why not join, or gift membership, today?!  

At the hub of this thriving community of volunteers and supporters, the staff team arranges forums, events, training, campaigns and research projects that channel the huge energy and expertise in the wider community, while ultimately strengthening and energising that same community. 

Our small size has allowed us to be agile and respond to urgent challenges quickly and efficiently – such as the discovery of the non-native Greater White-toothed Shrews in Britain in 2022. It also means our overheads as a charity are low – ensuring that we can put every penny of membership fees and donations to good use in our work to ensure a bright future for mammals.

The world has changed a lot in the last 70 years. Have the key purposes and goals of the charity evolved during this time to adapt to this changing world, or have they broadly remained the same? 

Conservation science is powerless without first being able to answer the questions ‘what to conserve?’ and ‘where to conserve?’; to do this we need to know, for each species, how large the population is, where it is (and was) distributed, and its status, threats and requirements. This science is exactly what The Mammal Society has been promoting since its inception, seeking to ensure that whatever the approach needed, it is undertaken in the right way – informed by science and data. 

This central remit has certainly not changed. However, the role of The Mammal Society in the conservation sector was a hot topic of discussion in the first few decades. In 1963, a resolution was passed at a meeting that the Society should be ‘a scientific body to which those in authority can turn for factual information about mammals and mammal biology’, upon which to base a judgement of the conflicting claims of different champions. To be accepted as such a body, the Society should not itself become involved in any way with […] controversial matters. In other words, The Mammal Society should gather and present scientific facts but not campaign for any particular action to be taken. This perspective shifted within ten years, with members wanting the Society to be prepared to call for action where it was scientifically justified. Nowadays we certainly consider ourselves to have a key role not only in establishing scientific evidence, but also in ensuring it is seen, understood and acted upon to bring positive outcomes for mammals. Communicating the science and advocating for its application are as important as the science itself if we want change. 

The other facet of our work that has become more important in recent years is communicating the importance and wonder of mammals to public audiences, in order to build public support for mammal conservation and encourage more engagement with life sciences – especially among younger people and communities currently under-represented in conservation. This objective is part of our remit to strengthen and energise the conservation sector. For example, our annual Mammal Photographer of the Year competition allows us to spotlight photographers who have captured beautiful and surprising images of mammals in the wild and inspire others to share in their wonder and excitement at spotting our elusive wild neighbours going about their everyday lives.  

In 1995, The Mammal Society entered a new phase when it established a network of local groups that could monitor the state of mammals in their area and respond to local issues while playing a key role in contributing to a better national picture of mammal populations. Through this process of evolution, The Mammal Society moved from connecting amateurs to professionals in mammal conservation, to providing anyone concerned about the decline of mammals with ways to get involved and directly help tackle the key issues. 

Some of these original groups are still going strong, and others have joined in the nearly 30 years since then. Led by volunteers, these groups provide opportunities for nature-lovers from all walks of life in their community to support citizen science activities that provide essential data and insight to inform mammal research, conservation practice and landscape management policy. 

Now we have more than 30 local mammal groups in the network, and their contribution to projects such as the Mammal Atlas, the Harvest Mouse Survey and many other projects cannot be under-estimated – as well as the profound impact many have had on mammal populations locally through their targeted efforts. The Mammal Society have sought to guide and support these groups over the years, but we feel there is much more we could do. 

Our new Local Mammal Groups Strategy (reflected in our new Local Groups Handbook) sets out how we intend to invest in growing, strengthening and diversifying the community of local mammal champions that participate in mammal conservation at the grassroots level through the local groups network.

Biodiversity loss and the climate crisis are key issues for everyone involved in conservation at present. What are your main goals for the coming years and decades?

Seventy years on, the challenges that need to be overcome to ensure a bright future for wildlife and people are just as daunting. This means that over the decades to come, our role as convener and mobiliser in the world of mammal conservation will be more important than ever. There is no doubt that reversing the loss of nature will require work from everyone, and the more joined-up those efforts are, the more positive the impact for wildlife and people. 

As we move into our eighth decade, we continue to do everything we can to foster collaboration and inclusion in mammal conservation. We aim to bring the scientific insight and expertise of our committees, members, council and staff to strengthen and support any initiatives that can help address the threats faced by our native mammals. As an active member of Wildlife & Countryside Link, we are already adding our voice to those of varied stakeholders across the nature sector to call for urgent action to address issues and redress shortcomings in policy and practice. Via European Mammal Conservation Europe, we have strengthened joint challenges on issues such as the protected status of wolves in the EU. We are active contributors to the RSPB-led UK State of Nature Report, and members of coalitions and steering groups on various species recovery strategies. We continue to engage with government to ensure that policy and priorities are informed by science. 

Our commitment to ensuring that everyone understands the importance of mammals, and can play a role in monitoring and protecting mammals, is reflected in our reinvigorated approach to supporting local groups – including an equipment loan scheme, free training for local groups, and an ambitious plan to see at least three new groups in currently under-represented urban areas by 2025. Alongside this our new school programme launches this year, creating opportunities for young people to explore and support mammals, and prioritising schools in areas of deprivation and serving communities under-represented in conservation.

Seventy years as a successful charity is an incredible achievement, not to mention the research, support and training you have undertaken and provided during this time. How are you marking and celebrating this important milestone? 

We’re spending 2024 looking back, and looking forward. We want to celebrate what’s been achieved over the past 70 years but also to take the opportunity to look at the challenges ahead and how we can all play a role in meeting them. 

To help us highlight this significant milestone, talented illustrator Silvie Tonellotto has designed our beautiful 70th anniversary badge, which will feature on communications throughout 2024. You can see more of her work on Instagram (@silvietonelottodesigns).

One of the key things we are focusing on is celebrating the people whose actions are key to ensuring a bright future for mammals, and especially to show the rich diversity of people and variety of roles people can play in supporting mammal conservation. We have therefore marked this 70th year with the launch of a new awards scheme – Mammal Champions. NHBS generously supported the prizes for the 2024 awards, and we’re delighted to have been able to shine a spotlight on some incredible volunteers, campaigners and thought leaders. 

National Mammal Week (celebrated in the autumn in previous years, but now moving to a new home in the spring) is 22nd to 28th April 2024. We’ll be celebrating the wonderful individuals shortlisted for Mammal Champions Awards, while also providing loads of opportunities for anyone in Britain and Ireland to find ways to become mammal champions in their own lives and communities.

Toads in the Roads

It is in the earliest months of the year, when the weather turns milder and deeply saturating rains arrive, that adult toads, frogs and newts begin to emerge from their wintering hibernacula and make their long-standing annual journeys to the waterways in which they breed. It’s an ancient way of life for amphibians and a behaviour that pre-dates humankind by millennia.

Roads are a relatively new addition to the landscape by comparison. A blink of an eye in toad evolution. They frequently bisect the paths that amphibians must navigate in order to reach their ancestral ponds. Being relatively slow-moving, small, and cryptically coloured, amphibians are incredibly vulnerable on tarmac roads. As such, it is estimated that two tons of toads are killed on roads each year in the UK.

This February was one of the warmest and wettest on record in England, and it felt every bit of it. Despite the gloom of early darkness and torrential rain, I was thrilled to sign up and join an enthusiastic local volunteer group of Toad patrollers, deep in the Devon laneways, to learn what work is being done to mitigate our impact on the amphibians currently making these critical journeys.

The Toads on Roads project was spearheaded by the amphibian charity Froglife over twenty years ago. Volunteers that are involved in the project put in considerable effort each year to monitor known and established toad crossings around the country. These are the places where toads gather in their largest numbers and are at significant risk of being run over in their attempts to reach spawning ponds.

The group I joined have, for a number of years, been protecting an intersection where three roads meet beside a large pond. As we gather in high-vis vests at around half five in the evening, it’s already fully dark. We’re wearing latex-free gloves and bearing large white buckets. The pond is swelling up either side of the road, flooding the tree roots in a muddy soup. The rain falls intermittently and, sure enough, a proud collection of male toads is already eagerly lining the roads awaiting the females.

We walk along the lane counting the toads we find and placing markers near them that are more visible for passing cars than the toads themselves are. It’s not such a busy road, but it is narrow and steeply enclosed between old earthen hedgerows that cars and tractors have clipped away over time, resulting in an overhang that the toads are incapable of climbing. Often, they become trapped along the lane. Where we find them in a predicament, we watch to observe the direction of their travel, and if the cars come, we gently lift the toads off the tarmac and place them in the verge where they appear to be headed.

A few drivers who come by slow down and ask what we’re doing. Many seem intrigued by the response, often vowing to take care as they go on. I’m told this is an improvement. As awareness of toad crossings and the work being done to monitor them increases, people are more understanding, though I’m assured there’s still animosity from some drivers who feel inconvenienced.

During some of the evenings on the patrol we encountered beastly weather; driving rain and flooded roads; and I marvelled at the dedication of the volunteers and their care for the amphibians crossing the roads. I learned that more people are approaching Froglife to get involved and that, due to increased awareness and publicity, the plight of toads is reaching more and more would-be patrollers. There have also been successful cases of temporary road closures to divert traffic during the heights of toad migration in the UK this year.

It’s a complex web of challenges that contribute to amphibian population declines – not just nationally but globally. Land-use intensification threatens our waterways with myriad pollutants and our roads and construction projects fragment vital habitats or obliterate them entirely. It’s heartening that awareness is building. It has been such an inspiration to me to learn there’s a network of enthusiastic and caring volunteers out there in the winter nights, working at limiting the damage to amphibian populations, championing these remarkable and charismatic animals, and building hopeful connections in local communities while doing so.

If you feel call to get involved, visit the Froglife website where you can learn more about local toad crossings. There’s also abundant information on ways that you can make any local green spaces or gardens more amphibian friendly, such as making ponds, allowing wilder patches and encouraging greater invertebrate diversity.

The Big Garden Birdwatch: NHBS Staff Results 2024

Greenfinch perched on a piece of metal.

The RSPB’s 45th Big Garden Birdwatch took place between Friday 26th and Sunday 28th January 2024. This annual event is one of the largest citizen science wildlife surveys in the UK and helps us gain an understanding of how our garden bird populations are changing in abundance and distribution over time.  Over half a million people took part in last year’s event, recording a total of 9.1 million birds. House Sparrows took first place, despite a gradual 57% decrease in sightings since the first Birdwatch Count in 1979. They were closely followed by the Blue Tit and Starling. 

Although the Big Garden Birdwatch has finished, there is still time to submit your results on the RSPB website by the 18th February, or by post before the 13th February. Even if you didn’t see anything, it still counts! 

With birds being faced with an increasing number of challenges each year, it’s more important than ever to make your garden and outdoor space wildlife friendly. This can include installing bird feeders or tables which provide an important food source throughout the winter months when natural food sources are scarce., You can also provide clean, fresh drinking water in shallow containers such as bird baths or saucers, and install nest boxes for breeding in the spring. Also, don’t forget to regularly clean and maintain your feeders and baths as this helps stop the spread of disease. Head over to the RSPB website to find out more about how you can help your garden birds.

The Seal Project: Q&A with founder Sarah Greenslade

The Seal Project text written in a circle with a multicoloured seal pup in the middle.The Seal Project is an environmental conservation charity based in Brixham, Devon, which monitors, surveys and manages the welfare of seals on and around the South West coast, particularly Torbay and South Hams. Alongside seal conservation, the charity also focuses on engaging, involving and educating the community on the importance of protecting our ocean wildlife through presentations, talks, assemblies in educational settings, workshops and public events. Sarah Greenslade spent many years working as a key member of the British Divers Marine Life Rescue before establishing The Seal Project in January 2019. 

Sarah, founder of The Seal Project, took time out of her busy schedule to answer our questions on the amazing work of The Seal Project, the effects of climate change on the local seal population, the importance of raising awareness, and how the current pupping season is going. 


What is the Seal Project and where are you based?

The Seal Project is a small conservation charity based in Brixham that monitors the Grey seals in South Devon – mostly around Brixham, but we now also monitor the coast between Dawlish and Prawle Point, including the River Dart. The charity was born out of a need to protect the seals seen locally, many of which are animals we know individually from all around our stretch of coastline. 

How did you get into seal conservation?

The story began when I encountered a Common Seal Pup stuck in Brixham’s Shoalstone seawater pool – who do you call at 5.30 in the morning? Myself and my best friend had no idea. The RSPCA don’t wake up that early and we had no clue what to do, but we knew that leaving the pup where it was wasn’t an option as people were walking dogs and the seal was clearly in the wrong place. My partner Lee (now a trustee of The Seal Project) suggested wrapping it up in something and putting it back in the sea. We had no hoodies or coats, so my friends partner was called and he brought down their most luxurious fleecey blanket off their sofa (as you do!) The seal, who had been swimming in the pool, came out and literally stopped at my feet. I scooped up the pup in the blanket as if it was a sleeping child and it never struggled once. We never touched it as we carried it over the rocks to the sea and let it free. As soon as we released it, another seal appeared – knowing what I know now that was most likely its mum – and off they went. The pup had clearly come in on a high tide and got stranded and the mum couldn’t get through the railings. If that was a grey seal it would have been abandoned there and then but Common seals are more devoted mums, and I hope to see this seal as an adult at some point.

After this, I became a Marine Mammal Medic for the British Divers Marine Life Rescue (BDMLR), which sends medics to call outs for marine life in distress, mostly seals, dolphins and whales. My first call out was to a ‘speared’ seal which quite literally resembled a tv ariel in the sea. She was eventually sighted locally without the spear attached, however it seems that every seal has some kind of back wound. She, like all seals, has unique identifying marks including their individual fingerprints and fur patterns, in this case a specific ‘W’ shape to the right-hand side of her head. I knew I had a photo showing that she was alive and well, and that resighting along with later  identification of an animal known by the Seal Research Trust (Cornwall Seal Group Research Trust), with whom we share all our data, are what first sparked my interest in using photos to identify individual seals. After providing the identification I spent two weeks getting called out to every seal sighting in search of the previously speared individual, and it’s all gone a bit mad since then!

We are at the end of October, which is around the time Seals finish pupping. What has it been like in the Torbay area for pups this year? 

I’ll be honest, it has not at all been as expected. Three of our known mums have not been seen for ages, and a first-time mum has been identified as a seal we know which we didn’t expect to be pupping just yet. The strange summer/autumn weather also means people are now using the coastline with their watercraft year-round and paddleboards and kayaks are now easily affordable too, so people are everywhere. Pupping seals who once had the coastline to themselves once September kicked in are now finding they don’t have these spaces to themselves, and as such pups are born or washed up in busy locations. This often results in a call out to BDMLR (as has just happened on the day I’m writing this).

Being based in a tourist area, what challenges do the seals and The Seal Project face? 

That’s a good question. Hand feeding is probably our biggest problem. When we first started, our mentor and amazing friend Sue Sayer MBE thought that us starting a Brixham-based project would have a negative response as this is a major fishing port and some believe that seals ‘eat all the fish.’ But bar the odd comment, and a tiny number of incidents involving fishing and tripper boats hand feeding seals, we have experienced very few problems with the commercial operators in Brixham.

As a tourist area another big problem is angling-line entanglements. Our Breakwater is a busy area for novice anglers and they tend to feed the seals in an attempt to make them go away – clearly that doesn’t work. Also, some seals are sadly too habituated and get caught in angling line regularly. With adult seals there is nothing that we can do about this, and they have to be left to themselves until the hooks rust or fall out. Stones are also often thrown at seals to make them go away, and the animals are uncommon at a couple of locations where more ‘commercial’ land angling takes place.

Our biggest challenge is lack of awareness. We spend so much of our time trying to raise awareness and get the message out there which requires help from the local authorities and the tourist boats, but this doesn’t seem to be happening and it’s frustrating for us. We should all be working together, and the amazing local wildlife – including seals – should be respected and appreciated. Without our incredible wildlife many tourist boats would just be ferry services.

What projects or research have you been carrying out or got planned for the future?

We monitor and record all seals, sightings, dates and locations to try to build up a big picture of the seal population around our coastline. We now know many seals well and have been gathering data since 2016/2017. Matching our seals to individuals from Cornwall is difficult as there are very few other locations on the south cost carrying out monitoring in this way. Therefore, unless an image of a seal happens to be shared on social media or passed onto us from a private group, our records are mostly limited to the confines of our study area.

We do however have sightings of seals which have been released in Cornwall or seen in north Cornwall. We would love to be able to find out where else our seals have been seen and to build a better picture of their travels. Given that we do have Cornish seals visiting our area, we’d like to know if they behave differently to the individuals normally resident in Devon; my Cornish surveys show that the seals there are much more skittish than the individuals we see in Brixham, which tend to be relaxed and show little concern around the noise and traffic of this major fishing port. We do also have a couple of students planning research, but as of yet nothing is confirmed. Our data is not in the best shape and every sighting of each seal takes time to document – identifying one seal can take seconds or hours, and as this is all done by eye the catalogue is a minefield to get involved in! 

How has climate change impacted the local seal community? 

At this time, I can’t say for sure. My biggest concern is the fact that seal pups, born with white fluffy coats to be camouflaged in snow, are increasingly being born in hot September sunshine, and therefore once abandoned they are at a greater risk of dehydration due to being on sunny warm beaches when it should be much cooler. This year, numbers of seals appear to have been increasing unusually slowly as we head towards the winter months, but we’re yet to reach peak winter season to be able to confirm whether numbers will remain low. Our only other concern at this time is for the three mums who we’ve not yet seen pup this year, as they’ve been so predictable for the past few years.  

Do you have a success story you’d like to share with us?

We first encountered him in 2020 as a juvenile seal entangled in industrial strength plastic. He vanished and we feared the worst, however a week later, on Easter Sunday, he was back in the same haul out spot on a girder in the marina, freed from the plastic. At the time of our first sighting, he appeared to have a bunny shape on his right-hand side (alongside a letter ‘A’), but this time the bunny seems to have disappeared with the ‘A’ is clearly visible. He reappeared regularly over the coming years, often seen for a few days and until the last several months always in the same spot, before disappearing for a few days and coming back again. We have seen him elsewhere a number of times, and last winter he was seen socialising with two ‘tagged’ seals (former rescued seals with plastic rear flipper tags for identification), so we look forward to seeing if they return to the area soon too.

Conservation volunteering with Wild Planet Trust’s Seagrass Project

I recently had the opportunity to witness first hand a team from the Wild Planet Trust working to survey seagrass meadows in the Torbay area. The ‘Save Our Seagrass’ project, which has been going for some years, involves repeated survey work throughout the year to assess the meadows’ health and the diversity of marine life that they support.  Having lost over 90% of seagrass meadows around the UK in recent centuries, these surveys provide vital information about the growth or decline of existing meadows, as well as potential impacts from factors such as global warming.

Megan and her team of volunteer divers met with me early on a Saturday morning to travel out into the bay to survey three specific meadows: Fishcombe Cove, Torre Abbey and Breakwater Beach. Each of these meadows carry unique characteristics derived from their locations. Torre Abbey is situated close to the harbour entrance of Torquay and is very shallow during low tides. The Breakwater Beach area is home to local swimmers and tourists.

The third site, Fishcombe Cove, near the fishing town of Brixham, holds a key to solving one of the problems that has contributed to the deterioration of the meadows. There are typically many reasons why a meadow sustains damage and/or gets wiped out, the most obvious being where fishing nets are trawled across the seabed. But more and more these days, casual leisure boat users cause damage by dropping their anchors. When damage occurs, it can take ten years or more to recover, assuming that the conditions are favourable.

An innovative approach to solving this problem has been using the deployment of “no anchor” buoys such as those that are situated in Fishcombe Cove. Designed to allow up to three boats to moor without dropping anchor, these buoys are chained to the seabed and have smaller submerged buoys attached to them which keep the chain from scraping the seabed and damaging the seagrass.

The surveys such as the one I observed use two different methods: a transect and a spiral form, and each dive team is equipped with a float with a GPS unit that stays on the surface and records their location as they move through and around the seagrass meadows. Each diver carries two hours’ worth of oxygen to be able to carry out the surveys at anywhere up to ten meters depth.  With underwater cameras they record the general health of the area and any unusual sightings along with expected marine life.

One of the observations from the divers from the surveys that I attended was the extent of life that had grown on the chains for the buoys, along with shoals of Bib (Trisopterus luscus) that were using the seagrass for cover. Around the meadow near Torre Abbey, plenty of additional life was found including Pipefish (Nerophis ophidion), Common Cuttlefish eggs (Sepia officinalis), Hermit Crabs (Pagurus bernhardus), gobies, periwinkles and Sea Slaters (Ligia oceanica).

All the data from the dives will be collated and, following a single additional dive day schedule in October, the team at the Wild Planet Trust will start the process of analysing the collected date from this year, looking at how the meadows have changed in comparison to previous years.
