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.

To find out more about the innovative work by Wilder Sensing, their blog features some interesting case studies on the applications of their technology and they are also active on LinkedIn. For more information on Wilder Sensing and their product, email info@wildersensing.com.

Wildlife

Ambitious project in south-west Wales aiming to restore one of the world’s most important habitats is getting underway. Two species of seagrass, Eelgrass (Zostera marina) and Dwarf Eelgrass (Zostera noltii) are being grown in ponds fed with seawater pumped in from the nearby Carmarthen Bay, and over the past two years alone this project has processed 1.5 million seeds. These have subsequently grown tens of thousands of plants that are now being reinstated in the wild to help restore the UK’s underwater seagrass meadows, 90% of which have vanished in the past 30 years alone.

Thriving Ecuador bird tourism is incentivising farmers to turn their agricultural land into nature reserves. Ecuador is home to over 1,600 species of bird, almost double the number found across the whole of Europe. As the country’s birding tourism grows, increasing numbers of farmers are turning their agricultural land into nature reserves to help preserve their stunning local wildlife. This is not only benefiting nature, but also the country’s economy as wildlife tourism offers a much more profitable livelihood than farming, resulting in some farmers expanding their land’s potential further than any traditional farming model would have provided.

Critically endangered Devils Hole Pupfish population reaches a 25 year high. This rare species lives in the smallest known desert habitat of any vertebrate and is only found in the upper areas of a single limestone cave in the Mojave Desert, Nevada, where the whole population resides on a single shallow rock shelf. They have evolved to be able to withstand harsh desert conditions, including very high water temperatures and extremely low oxygen levels. In 2013, their population fell to just 35 individuals, but careful conservation efforts over the past 11 years have offered hope for this rare species as their population has now reached a 25-year record high of 191 fish.

Environment

The North Atlantic is set to be hit by more than double the normal number of hurricanes this season, warns NOAA. Researchers have suggested that this is predominantly due to high sea surface temperatures as a result of the upcoming transition between El Niño and La Niña which helps these storms grow more easily. Although there is no evidence showing that climate change is a contributing factor, it is likely to exacerbate the severity of these weather patterns. Contrastingly, NOAA have predicted a below-normal hurricane season for the central Pacific region where El Niño and La Niña work in opposition.

Purbeck Heath begins its transformation into an ancient savannah habitat to help precious species thrive. The National Trust’s lead ecologist for Purbeck, David Brown, explained that the project hopes to use domestic grazers such as wild cattle, pigs, ponies and deer to mimic their wild ancestors and shape the 1,370 hectares of open grassland in Dorset into a dynamic, complex and biodiverse ecosystem. Purbeck Heath is already one of the most diverse areas in the UK, and this project will aid the recovery of rare and threatened species such as Purbeck Mason Wasps, Heath Tiger Beetles and Sand Lizards.

Climate

Increased ocean temperatures are undercutting the Thwaites Glacier and causing glacial melt from below. This glacier is currently losing 75 billion tons of ice per year, accounting for nearly half the total ice lost from Antarctica per annum. Scientists have revealed that an estimated 150 million kilowatts of thermal power are injected into the ice with each undercutting intrusion, which could melt 20 meters of ice off the bottom of the glacier each year. Recent simulation to assess the effects saltwater invasion may have on retreat rates has revealed it could double the overall rate of ice loss for some glaciers.

New research reveals the catastrophic effects of extreme heat, deoxygenation and acidification in the oceans due to fossil fuels and deforestation. In the top 300 meters of affected oceans, these compounded events are lasting three times longer and are six times more intense than in the 1960s. A fifth of the world’s ocean surface is susceptible to all three of these stresses at once, which has been further exacerbated in recent decades as extreme weather conditions have become more intense. Scientists warn that the extra CO₂ absorbed by the oceans has increased the temperature and acidity of seawater, is dissolving the shells of sea creatures and starving the ocean of oxygen. This series of events is comparable to those experienced at the end of the Permian period 252 million years ago when the planet experienced the largest known extinction event in its history.

Climate crisis

Unusual spring weather is affecting bird migrations. The Wood Warbler, Redstart and Pied Flycatcher migrate from sub-Saharan Africa to British oak woods every spring and depend on Oak Moth caterpillars to feed their young. In recent years, these caterpillars had already emerged and were pupating by the time the birds arrived, resulting in their chicks starving. This year, however, they are facing a new issue: as spring has been so wet and cold, many birds have not reached Britain yet, while those that have are having to search for food in cool weather and have not begun nesting. These shifts in long-term weather patterns are likely to continue to cause migration issues going forward due to their unpredictability.

The final Venezuelan glacier has been downgraded to an ‘ice field’ following large-scale glacial melt. This follows the loss of at least six other glaciers across the country in the last century due to an increase in global temperatures. In March 2024, researchers revealed that the Humboldt glacier had shrunk from 450 hectares to just two hectares. More recent observations show that, in the last two months it has reduced in size further to the area of just two football pitches. The latest projections suggest that between 20–80% of glaciers worldwide will be lost by 2100 as a result of climate change, with some of this loss already inevitable despite attempts to combat climate breakdown.

New record of Asian Hornet sightings threatens native pollination species. While Asian Hornets aren’t yet established in the UK, recent flooding and warm temperatures are increasing the risk of this species spreading across the country. Defra has warned that early detection and irradiation is the key to saving our native pollinator species who are known to feed on Honeybees. Since 2016, there have been 108 sightings of Asian Hornets, 56 of which were recorded last year alone. A further eight have been reported in the UK so far this year. Kent is on the front-line of the battle against this species with many of the UK sightings recorded in this county.

Pioneering project that makes eco-friendly concrete from crushed shells may be the answer to extreme flooding. A team at the University of Central Lancashire has developed an innovative, sustainable, permeable concrete made from recycled crushed scallop and whelk shells that would otherwise go to landfill when discarded by fishmongers. Trials are being undertaken in Blackpool to assess its effectiveness in gardens, footpaths and car parks, and early results are very positive.

Over 8,000 hectares of land ‘left to nature’ to increase biodiversity. This restoration project, run by Forestry England and supported by both Forest Holidays and the Government, will be implemented in four areas across the UK: Castle Neroche, Somerset; Kielder Forest, Northumberland; Newtondale, North Yorkshire and Purbeck, Dorset. The project aims to minimise human involvement, allowing nature to shape these forest landscapes itself. Andrew Stinger, The Head of Environment at Forestry England, stated that, although the team is uncertain how these areas will evolve once human activity is reduced, they are confident they will become more biodiverse with the help of reintroduction initiatives, aid flood mitigation, improve air quality, and restore soil health.

Study reveals that female Sea Otters are using tools to help preserve their teeth. Researcher Chris Law documented the moment that a female Sea Otter used a rock anvil to open the shell of its next meal, a type of behaviour which has previously been witnessed in very few animals. Further investigation revealed that, when there’s a decline in their preferred food, female Sea Otters have evolved to use tools to allow them to overcome their weaker biting ability when compared to their male counterparts, which allows them to consume alternative, larger prey without damaging their teeth.

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.

Half the world’s estuaries have been altered by humans, with 20% of estuary loss occurring in the past 35 years alone as a result of urban or agricultural land expansions. Ninety percent of this has occurred in rapidly developing Asian countries, whereas very little estuary loss has been noted in higher income countries within the same period. This is because waterway alterations in these higher income countries were made many decades prior during their own urban development stages. With much of the world now trying to undo this damage and rewild urbanised areas, countries are now investing in programmes to return these areas to wild mudflats and salt marshes which will increase climate resilience, replenish aquatic populations, reduce flood risk and aid nature’s recovery.

The introduction of new diseases via open import systems are destroying EU trees and crops, with outbreaks on the rise once again. This comes after a mutation of one of the major killers of Olive trees in Italy, Xylella fastidiosa, was detected in America and is now wiping out US vineyards alongside its Italian counterparts. New data has revealed that an average of 70 foreign plant diseases were introduced to the EU between 2015–2020, despite legislation being enforced to prevent their spread in 2016, and scientists are holding open systems accountable. According to international protocols, only 2% of imported plants travelling through open systems are inspected for the presence of diseases, meaning that an alarming number of plant pests may be brought into the EU undetected. Although some pathogens are harmless in areas where ecosystems have evolved alongside them, they can be deadly when introduced to a new area. As global temperatures continue to rise, the problem is only likely to get worse.

A UK study has proven that wilder gardens boost butterfly population numbers, with long, uncut grass likely to almost double butterfly abundance. This research, co-authored by the head of science at Butterfly Conservation, recorded a 93% increase in butterflies in gardens within farmed landscapes who did not cut their lawns, while gardens in urban areas noted an 18% rise in population numbers. These wilder habitats attract species whose caterpillars live and feed on the grass, provide greater quantities of nectar that are necessary for butterfly survival, and create important breeding habitats, which subsequently increases population numbers. The study advises that long grass should be left until late September or early October before cutting as some species require longer grass nearly all year round.

Music featuring the sounds of nature earn royalties that will be donated to environmental causes. This new initiative, launched by the Museum for the United Nations, will recognise nature as an official artist on major music streaming platforms. A share of the royalties earnt when these songs are played will be donated to environmental causes and initiatives who are working hard to protect nature for the future. Nature itself will also have its own artist page on Spotify which will showcase ambient recordings of nature’s sounds, with 70% of the profits from these tracks funding conservation programmes.

The south coast’s only breeding Osprey pair have laid a fourth egg. These birds became the first nesting Ospreys on the south coast for 180 years after their reintroduction seven years ago. They returned to Poole Harbour in late March after their migration to West Africa and laid their first egg on the 15th April 2024. As female Ospreys usually only lay 3 eggs due to the challenges of feeding 4 young, researchers were surprised to find a fourth, but due to the exceptional job the pair did while caring for 3 chicks in 2023 they have high hopes for success this season.

Discovery

Common Eastern Bumblebee queens have adapted so they can survive underwater for up to a week during hibernation, which is thought to be responsible for the species’ continual population stability, despite a third of all other bumblebee species currently in decline. This study was conducted as a result of water leaking into containers housing hibernating queens; results revealed that over 80% of the bees survived when submerged for up to seven days. Scientists noted that these findings are unusual as most overwintering insects cannot cope when submerged in water. However, it is hoped that this flood tolerance will help the species continue to thrive in the wild.

The largest snake that ever lived has been discovered in Western India, measuring up to 15m long and weighing a tonne. The fossil of the Vasuki indicus snake was discovered in a mine in western India and included 27 vertebrae, a few of which remained in the correct anatomical position. Scientists concluded that it would have lived in marshy swamps around 66m years ago during the Cenozoic era and, due to its size, it would have been a slow-moving ambush predator who attacked its prey through constriction.

Equipment in Focus: Royal Entomological Society Bug Hunting Kits

The Royal Entomological Society (RES) is an organisation dedicated to advancing the field of insect science. Through encouraging open communication, research and publication, the RES hopes to enrich the world with entomology.

Developed in collaboration with the RES, the Royal Entomological Society Bug Hunting Kits provide naturalist users with the tools to safely capture, observe and identify British insects. Kitted with sweep nets, collecting pots and a pooter to capture your insects, you will also be provided with a hand lens, ID guide and optional forceps for identification of species you find.

Suited for aspiring entomologists, The Royal Entomological Society Educational Bug Hunting Kit includes a copy of A Naturalist’s Guide to The Insects of Britain and Northern Europe. The Royal Entomological Society Advanced Bug Hunting Kit provides a technical alternative for more experienced naturalists, with additional pointed forceps and the Collins Complete Guide to British Insects. Here we take a closer look at what’s included in these exclusive kits.

As seen on Countryfile, the Standard Sweep Net provides users with a simple, lightweight (280g) net for catching invertebrates. The short, 15cm handle has a foam grip for improved control and a lightweight aluminium frame. The net itself is made in the UK and features a soft calico bag attached via Velcro to the frame, making it easy to remove for washing.

At the core of this kit is the NHBS Insect Pooter. Expertly designed and manufactured at our facilities in Devon, this piece of kit can safely capture a wide range of invertebrates. Affordable and simple to use, this item allows the user to observe specimens in a see-through chamber. The chamber is topped with a 2.5× magnification lens for easy viewing and identification. The pooter’s components can be removed and cleaned for sanitation between sampling.

Each kit comes with five 60ml Collecting Pots for specimen handling and collection. The collecting pots have secure screw-on lids, made with see-through polypropylene for easy, clear viewing.

The handy Double Loupe Hand Lens provided with this kit is only 30mm in diameter, comprising two silicate glass lenses, 5× and 10× magnification. The lenses of this sturdy pocket magnifier fold into a protective casing, keeping them clear from scratches between use. Lightweight and compact, this hand lens is highly portable and is ideal for people of all ages.

Made from a non-magnetic stainless-steel alloy, the Super Fine Pointed Forceps are manufactured with fine points for precision use. Included with the Advanced Bug Hunting Kit, these precise forceps are not serrated to minimise damage to delicate specimens, and at 11cm are a handy size for transportation and use in-field.

Provided with the Advanced Bug Hunting Kit, the Collins Complete Guide to British Insects is a photographic field guide to common and unusual insect species across Britain. This extensive work covers over 1,500 species, providing descriptions and detailing where, and when, to observe them. With detailed photographs for each species, differences between similar organisms are highlighted to aid identification. This book covers a range of insects, from bugs and bees to moths and mayflies.

A Naturalists Guide to the Insects of Britain and Northern Europe is provided with the Educational Bug Hunting Kit. This easy-to-use ID guide is ideal for nonspecialist naturalists, with high quality photos of over 280 insect species. A description of appearance, associated habitats, habits and conservation status are outlined for each species. The guide also includes life cycles and describes the conservation of the group.

The mission of The Royal Entomological Society is to enrich the world with insect science- doing this through events, books and supporting young people in gaining skills in entomology.

The Royal Entomological Society receives 10% from the sale of this kit to support their cause.

Spring Exploring: Equipment for Wildlife Watching

As spring emerges, naturalists across the UK are dusting off their kit to begin exploring the great outdoors. From bird watching to bug hunting, we have equipment to help you explore. Below, we have compiled a list of must-have equipment for wildlife watching this spring.

Viking Cygnus Monocular

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!

This Week in Biodiversity News – 15th April

Environment

The UK’s first national assessment of earthworms has revealed that their populations decrease by 2% annually, and overall earthworm population numbers have fallen by a third over the past 25 years. This study, conducted by an ecologist at the British Ornithology Trust (BTO), also concluded that the largest decline in this species has been observed in broadleaf woodland ecosystems. This may now be having detrimental effects on other species, such as woodland birds, who have seen a subsequent population decline of 37% since 1970. Barnes’ study concludes that, if these results are found elsewhere, the long-term decline of this keystone species could affect our ability to grow crops, as worms aid the growth of 140m tonnes of food a year. It may also have catastrophic effects on soil health, ecosystem structure, function, and above-ground wildlife.

Global rainforest deforestation continues at a rate of ten football pitches per minute. Despite widespread efforts to minimise deforestation across the Brazilian and Colombian Amazon, new data has revealed that 37,000 sq km was still removed from previously undisturbed rainforests in 2023. Large increases were noted in Bolivia, Laos and Nicaragua, which has now offset the positive progress made by other countries in the reduction of deforestation. Experts have warned that governments are unlikely to meet their climate and biodiversity commitments due to the continuation of mass deforestation, with many going against the COP28 agreement to halt and reverse the loss and degradation of forests in the next six years. This puts the 2030 zero-deforestation target even further out of reach.

New research has revealed that national parks are failing to tackle the biodiversity crisis, despite these important areas covering 10% of England and 20% of Wales. Due to lack of government funding, the direct grant set aside for national parks has been cut by 40% since 2010, resulting in poor peatland condition, no change in woodland biodiversity in a 5-year period, and a significant decline in river and lake health. Aside from a lack of funding, national parks are not restoring nature as only 13.7% of the land is publicly owned, with the remaining 86.3% privately owned and often intensely farmed. Campaign for National Parks is calling for a new deal that ensures the government sets a clear mission to increase nature protection and restoration in the UK’s national parks, and subsequently double core national park grants to reinstate this vital funding to its 2010 level.

Discovery and reintroduction

One of the world’s most elusive moles has been sighted in Australia. The Northern Marsupial Mole, or Kakarratul, lives in one of the most remote parts of Australia and is only sighted a few times each decade. Due to their rarity, authorities are still unsure of their population size and these creatures remain a mystery to most of the world. However, the Kanyirninpa Jukurrpa Martu rangers discovered the rare, blind Northern Marsupial while working in the Great Sandy Desert, making this the second species sighting in six months.

Progress has been made in the first ever shark translocation project, which aims to reintroduce Zebra Sharks to the Raja Ampat archipelago in Indonesia after the species was declared functionally extinct due to overfishing and habitat degradation. This is the first initiative attempting to translocate shark eggs from an aquarium to a hatchery before releasing them into the wild. Two sharks have recently hatched on the island of Kri and will be kept in tanks until they are strong enough to be released into the wild. The project aims to release 500 Zebra Sharks by 2032 in the hope of creating a genetically diverse breeding population that will aid long-term species recovery. If successful, this rewilding project will set a strong example of how to re-establish endangered species populations in marine ecosystems and would be a breakthrough for future conservation efforts.

Climate crisis

A record hot March leads to fears of faster rates of climate change. Last month was the hottest March on record, reaching 1.68°C warmer than in pre-industrial times. This marks the tenth record breaking monthly temperature in a row, and scientists are concerned that they may not temporarily fall, as expected, after the El Niño period due to the warm weather experienced at the end of 2023. Researchers are now trying to ascertain whether the changes in El Niño are a phase shift or just an anomaly in long-term climate trends. Although they are unsure how conditions in the Pacific Ocean will evolve over the coming months, current predictions suggest it could be replaced by a full La Niña cooling phase.

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.
