This week in biodiversity news – 18th March 2024

Climate 

The price of bananas is set to rise permanently as a result of climate change, according to experts. This follows a noticeable absence of the much-loved fruit in several UK supermarkets within the past few weeks due to sea storms. Senior economist at the UN’s Food and Agricultural Organisation states that increasing temperatures are compounding the impacts of fast spreading diseases, including the Fusarium Wilt TR4 infection, which continues to pose an enormous threat to supply chains. Once a banana plantation has been infected with the virus, it kills the trees, therefore halting production. The infection is very difficult to eradicate once present. Increases in more extreme weather conditions, such as widescale flooding and strong winds, allow the virus to spread more easily and may be why it has now been detected across four continents.

The world’s largest species of tree is thriving in the UK due to the moist climate, and now outnumbers those in their native home of California. A study into Giant Redwoods (Sequoiadendron giganteum) has revealed that those imported to the UK around 160 years ago are growing at a similar rate to those in the US. However, as these trees are still young, they are 39% smaller than their American counterparts. Due to their sheer size, it has also been revealed that they store large quantities of carbon dioxide, with those measuring 45m tall in Wakehurst storing between 10-15 tonnes of carbon per tree. Whilst the trees are flourishing in the UK climate, there is little chance of them invading native forests as they require very specific conditions to seed. 

Environment 

An African project aiming to replace barren lands with wildlife-rich, biodiverse forests has restored more than 41,000 hectares of woodland in ten years. Trees for Future (TREES) is an organisation that aims to restore landscapes in developing communities, while also combating poverty. Following the launch of their mass reforestation campaign in 2015, they have worked with locals to plant tens of millions of trees across nine African countries. They also intend to create 230,000 jobs by 2030 via their ambitious initiative. Working with thousands of smallholder farmers for a duration of four years, they provide training, tools, seeds and grants to allow locals to plant biodiverse woodland and create environments that are self-sustainable for both communities and nature.

The government has pledged a £25m scheme to restore critically endangered habitats for England’s fastest-declining wildlife. In light of the recent announcement of the EU’s first nature law to restore 30% of degraded ecosystems by 2030, this government funding will help improve over 3,300 hectares of land, including 49 hectares of wetland around chalk river habitats in south-east England. The ‘species survival fund’ will also support schools, farmers and landowners across mid-Cornwall to ensure woodland, heathland and acidic grassland restoration across the moors, and help to create vital nature corridors across the Medlock Valley, with the collective aim of restoring nature and supporting iconic species such as Water Voles, waxcaps and rare Great-crested Newts. 

Science 

According to a new study, playing healthy reef sounds through underwater speakers could save damaged coral reefs. Fifty percent of the worlds coral reefs have been lost since the 1950s. However, scientists working in the Caribbean have revealed that simulating healthy coral reef environments through soundscape recordings may be the key to recovery. Working across three reefs, each at different stages of degradation, the team of scientists installed speakers at all three sites, but only played recordings taken from a thriving reef at one: Salt Pond reef. Results showed that, on average, 1.7 times more coral larvae settled there than on the other two sites. The rate of settlement decreased further away from the speakers, suggesting that the sounds played an important role in larval retention. Research is now underway to understand whether other coral species respond in the same way, and to find out whether the corals thrive after settling.

Pollution 

Air pollution levels throughout Europe have continually decreased over the last 20 years, despite increasing threats of climate change. Research conducted by the Barcelona Institute for Global Health studied 1,400 regions across 35 countries and have concluded that the two main forms of overall suspended particulate matter (PM2.5 and PM10) and nitrogen dioxide (NO2) have been falling annually throughout this period. PM10 has decreased annually by 2.72%, while PM2.5 dropped by 2.45% and NO2 levels reduced by 1.72%. These tiny pollution particles are known to cause an array of health problems, and over 200,000 of related cases have been deemed preventable if European air quality met WHO guidelines.

Neil Middleton on the 4th edition of Bat Surveys for Professional Ecologists

The 4th edition of Bat Surveys for Professional Ecologists: Good Practice Guidelines is the latest update of the Bat Conservation Trust (BCT) Guidelines and features new content on biosecurity, night-vision aids, tree surveys and auto-identification for bat sound analysis. Several key chapters have been expanded, and new tools, techniques and recommendations included. It is a key resource for professional ecologists carrying out surveys for development and planning.

Neil Middleton is a licensed bat worker and trainer. He is the Managing Director of BatAbility which offers bat-related and business skills development courses and training throughout the UK and Europe. He kindly agreed to take the time to write an article for us which will help ecologists and bat workers assess some of the key content and changes within the 4th edition of the Bat Survey Guidelines, and evaluate how this is likely to impact you, your colleagues and your business.


I have been asked to write this blog for NHBS regarding the recently published 4th edition of the BCT Bat Surveys for Professional Ecologists: Good Practice Guidelines. Straight away I feel I should say that, broadly speaking, we (BatAbility) are supportive of the overall spirit of intent that these new guidelines are seeking to achieve.

The contributors to the finished work and the editor of the final draft will have, I’m sure, had much debate about the final wording of the guidelines. It certainly cannot have been an easy task to come up with approaches that a broad range of experienced people, each with different backgrounds, were able to fully agree upon (or at least not disagree). In addition to which, these guidelines need to cater for all the component parts of the UK, where differences in legislation, planning, licensing etc. apply.

What follows are my thoughts on why you need to be up to speed with what’s happening. When I discuss some of the points you need to be aware of, it’s not that I am criticising or disagreeing with what has been produced, it is more that I am encouraging you to think about things that may not immediately be apparent when it comes to impacting (positively or negatively) upon your daily business operations.

Broadly speaking, these Good Practice Guidelines are what we all need to be referring to now for guidance and, barring any new properly released formal material direct from BCT (i.e. it doesn’t matter what someone says on a social media post or during a webinar) that either updates, changes or gives additional explanation to what is in the 4th edition, this is where we, as a community, are at. BCT have confirmed that a few changes to the text will be made by way of an amendment document and this, in conjunction with printed Q&A material resulting from BCT webinars (November 2023 and February 2024), will prove to be essential complimentary reading for everyone relying upon these guidelines during their day-to-day work.

At this stage, I feel that it is also important to say, and BCT have been very keen to emphasise this point (e.g. during their webinars on the subject), that the guidance is very clear about deviating from its approaches where specific cases and/or experienced, professional judgement suggests that a different approach can be taken for good reason, provided that it is fully disclosed and discussed within generated outputs (e.g. reports going to local planning departments). The material produced is described as ‘guidelines’ after all, and should not be used prescriptively when common sense, good scientific rationale or proportionality, as examples, suggests otherwise.

These updated guidelines were keenly awaited by bat workers for some time leading up to their publication.The driving force behind the update was thought mainly to be the integration of Night Vision Aids (NVAs) into our bat survey approach, as initially described within an Interim Guidance Note published in May 2022 and covered in this article on the BCT website.

I mention this for two reasons. Firstly, it’s what I feel almost everyone was genuinely expecting. Secondly, these revised guidelines don’t (as anticipated rightly or wrongly!) fully address some of the specific aspects of where the NVA debate is going to finally arrive. Regarding this aspect of bat work, the finer detail around this matter is now being tackled by a review panel, and BCT will inform us as/when they are in a position to do so. In the meantime, the Interim Guidance (2022) remains as an additional, essential point of referral. Having said that, within these new guidelines there are regular pointers, reminders and requirements that NVAs should be incorporated within survey design.

So, why do we need to pay any attention to these new guidelines? If they are not telling us about the specifics of the NVA approach, then you may very well think that there’s not much value in getting your own copy and reading through, yet again, what was there before. Yes, you may very well think that. Yes, you would be very wrong.

There is so much in here that is going to make your life as a bat consultant different to how it was up until last year (2023). There are undoubtedly elephants potentially in some people’s rooms. But an hour after sunset when it’s too dark to see, some people may not be aware that elephants lurk (well not unless they have an NVA, and it’s pointing in the right direction). There are resourcing implications, cost implications, tendering implications, health and safety implications – there are all of these and more that you need to be aware of. And by implications I mean a mix of positives and negatives. It is a classic situation whereby in solving a range of issues and making clarifications on others, new issues and opportunities inevitably arise.

From a surveyor’s point of view, the dreaded dawn work is mostly redundant, although I feel there are still going to be occasions from a bat behaviour point of view, and from a health and safety point of view (e.g. working within busy town centre areas) where dawns could still occasionally be a better, or even a desirable approach. The guidelines certainly don’t say you should never do a dawn survey again, full stop.

From a business owner’s perspective there are matters that will need serious consideration and budgeting for. This could impact (again negatively or positively) upon your turnover, your approach to tendering, resourcing, the deployment of staff and equipment, as well as the careful balancing of your team’s time at their desks versus time in the field. All of this, of course, needs to be considered against the benefits to bat conservation. The challenge on the business model is not necessarily a bad thing, provided you are fore-armed and have seriously thought through how these changes impact upon your organisation.

Please don’t construe that I am not supportive of what these guidelines are seeking to achieve. In many respects, from a conservation perspective, I feel things have moved closer to where they should be. Balanced against this, however, I urge you to be aware that you need to get your head around the new approaches as a matter of urgency, and build into your day-to-day workings methods of adapting to the changes.

There is neither the time nor the space to cover it all here, and to do so would merely be to repeat what was contained in the guidelines in any case. What I am seeking to do is alert you to the fact that, despite how much you may have seen on social media etc. relating to the NVA debate, there are arguably equally as BIG matters contained within the new edition that don’t relate to the use of NVAs.

Here are some key points of where things have really changed, in my view:

  • Dawn surveys are pretty much redundant, as we are now pressed to doing dusk surveys with NVAs. This is great from a work-life balance, but it also removes up to 50% of the previously available time slots on your survey calendar.
  • NVAs are to be deployed on pretty much every emergence survey, covering the survey subject as fully as possible, with the associated implications for reviewing all that footage and storage of data. Video footage is much larger than the pure audio that you will have been accustomed to.
  • A licenced bat worker is required to be present for any field work where a licensable situation could occur, no matter how likely or unlikely, be that structures or trees. Following the definite statements in the 4th edition, there is no longer any ‘wiggle room’ on this issue.
  • Bats and Trees – aerial assessment (be that by ladder, rope or MEWP) is pretty much the desired approach, meaning that this will be a greater part of these jobs and, in conjunction with this, licensed bat worker(s) will need to be present.
  • Due to the increased requirement for licensed bat workers to be present far more often than previously was the case, and the increase in tree climbing work where licensed bat worker(s) should also be used, there are resourcing implications that need to be considered when it comes to training in these areas. It is important to be aware that not every licensed bat worker within a business is either capable of or desires to climb trees. Also, in some business models, the licensed person/people are in more senior positions where their presence in the field conflicts directly with the role they are being asked to perform for the business (e.g. team management, client meetings, tendering, business process improvement). So, for some businesses, depending upon their current resources of licensed bat workers, there may need to be a rethink.

What I have described above is most definitely not the full suite of changes, but hopefully it’s enough to demonstrate that you need to get on top of what’s in there.

The key message is, if you haven’t already got yourself a copy and read it through in detail, then as a matter of urgency you should do so. Then you will be able to consider how you are going to achieve what is required.

Author Q&A with Tim Mackrill: The Osprey

The Osprey book cover.Persecuted mercilessly in Britain, the magnificent Osprey became extinct in the 1890s. However, the return of the species to Scotland in the 1950s was the catalyst for reintroduction programmes elsewhere, and this remarkable raptor is now an increasingly common sight in our skies. This Poyser monograph includes over 150 photographs and details the distribution, migration, foraging ecology, breeding behaviour and population dynamics of this spectacular bird. It also places emphasis on the conservation efforts across the species British and African haunts, the latter of which has only recently been discovered thanks to satellite tagging technology.

Nature conservationist Dr Tim Mackrill completed a PhD on Osprey migration at the University of Leicester and has since worked with the Roy Dennis Wildlife Foundation on various reintroduction projects, including the return of Ospreys and White-tailed Eagles to England. He managed the Rutland Osprey Project for over ten years and is the founder of the Osprey Leadership Foundation, which aims to inspire the next generation of conservation leaders by working with young people who live along the Osprey’s migratory route. 

We recently had the opportunity to speak to Tim about The Osprey, including why he is so captivated by this species, the technological advances that have helped increase our knowledge of them and more.  


Your entire adult life, and indeed much of your childhood, appears to have been spent observing and studying Ospreys. What is it about this species that so captivates you? 

Anyone who has seen an Osprey will vouch for the fact that they are a spectacular bird, particularly if you have been fortunate enough to see one plunge into water to catch a fish. However, it is the species’ migration that I find so captivating. As I write in chapter 6 of The Osprey, whenever I see a newly arrived Osprey perched beside its nest in the spring, I always think it is rather humbling to consider what the bird might have experienced since leaving its wintering site a few weeks earlier: traversing the Sahara, negotiating imposing mountain ranges, crossing areas of open sea. It could even have flown through the night – its path illuminated only by stars and moonlight – with the urge to reclaim its nest a source of great motivation to power its way north. The fact that Ospreys are faithful to the same nest site each year, and that we know them as individuals, makes it even more special to see a familiar bird back home in the spring.

In the introduction of your book, you mention that there can be few bird species that are as well studied as the Osprey. What technological advancements over the past few decades do you think have been most influential in increasing our knowledge of this species? 

The advances in satellite tracking technology since the 1990s have added greatly to our knowledge of Ospreys. The most recent transmitters are able to log data at very high temporal resolution – as often as once per second in some cases – and this gives some amazing insights into the migratory journeys of individual Ospreys. It has shown how Ospreys are able to adapt their flight according to environmental conditions, and to make very long sea crossings – something that most raptors avoid. It has also demonstrated how experiences on the first migration shape the subsequent migratory habits of individuals, and also how young birds enter the breeding population for the first time.   

Historically, the persecution of Ospreys has been a large problem within Britain. Is this something that is still an issue? 

Fortunately, this is much less of an issue now. Egg collecting was a major threat during the early years of the Osprey recovery in Scotland, but has declined since the introduction of custodial sentences. Historically,  persecution at fishing ponds was a major cause of the population decline of Ospreys in the British Isles, and although the occasional Osprey is still shot, the sight of an Osprey plunging into the water at great speed, and then lifting off a few seconds later with a fish grasped in its talons, is much more likely to excite and inspire people than to create animosity. The success of an Osprey photographic hide at a working trout farm, Horn Mill, in Rutland is testament to that.

Ospreys appear to respond well to translocation projects. Is this down to the characteristics of their species, or because we have good quality research and evidence to indicate how best to undertake such projects? 

Translocation has been a key tool in helping the Osprey recover from the negative impacts of historical persecution and DDT. The first Ospreys to be translocated were in the United States in the late 1970s and in Europe, at Rutland Water, in the mid-1990s. As such, a wealth of information on all aspects of the translocation process has been developed and refined over the years, which means that more recent projects are much better informed than earlier ones. However, it is the species’ own breeding biology that is key. Young Ospreys, particularly males, are highly site faithful and usually return to breed close to their natal site. The imprinting process seems to occur after fledging and prior to migration and so, by moving young birds at around five to six weeks, when they are a fortnight from making their first flight, they regard the release site as home, rather than their natal nest. All young Ospreys undertake their first migration alone, and so as long as translocated Ospreys are provided fish after fledging in the way that wild-fledged birds are provisioned by their parents, they migrate as normal. Then, all being well, they return to the release site for the first time at two years of age.  

As a fully piscivorous species, do Ospreys suffer from ingesting water-borne pollutants or plastic waste? 

The Osprey is regarded as something of a sentinel species for environmental contaminant exposure and effects in aquatic ecosystems. It was badly affected by DDT in the United States and some parts of Europe. More recently, research in the United States has identified Polybrominated biphenyl ether (PBDE), flame retardants used in thermoplastics, textiles, polyurethane foams and electronic circuitry, as a potential emerging threat to Ospreys.  

PBDEs have been shown to bioaccumulate and biomagnify up the food chain, but unlike organochlorine pesticides which have declined in aquatic ecosystems in recent decades, PBDEs have increased since the 1970s. Plastic waste is also an issue, particularly in some of the coastal areas where Ospreys overwinter. It is a sad sight to see a wintering Osprey perched on a beach surrounded by ubiquitous plastic pollution.

When it comes to the Osprey, where are the gaps in the knowledge? What are the things that you’re still excited to find out about them? 

There are still elements of migration that we do not fully understand. We know that young birds use a process known as vector summation (an inherited programme of distance and direction) on their migration, and that adults become expert navigators as they become more experienced, but we do not know the exact mechanisms for this, though factors such as landscape features may be important. Personally, I like the fact that there is still this mystery around certain aspects of bird migration – it adds to the sense of awe that is created by the remarkable journeys of Ospreys and other species. 

Finally, what’s keeping you occupied day-to-day at the moment? And do you have plans for further books? 

One of the most exciting projects I am involved with at present, through my work with the Roy Dennis Wildlife Foundation, is the reintroduction of White-tailed Eagles to southern England. The first pair bred successfully last year and it has been exciting and encouraging to see how the birds are fitting into southern England. Like Ospreys, they take fish from the South Coast estuaries and so there is a wealth of suitable habitat for them. The fact that there are now breeding Ospreys and White-tailed Eagles back on the South Coast of England is very exciting and testament to what a positive, proactive approach to conservation can achieve. I love writing and so I definitely have plans for future books.  

A few years ago I also set-up a charity, the Osprey Leadership Foundation (OLF), which works to inspire and enable young conservation leaders. I feel very privileged to have had Roy Dennis, who wrote the foreword for The Osprey, as a friend and mentor for many years, and I hope the work of OLF will help the next generation of conservationists to follow the lead of people like Roy to undertake bold and ambitious projects for nature recovery – we certainly need it.

The NHBS Guide to UK Snail Identification

Snails are a common feature in our gardens and parks. You may have particularly noticed them if you have a vegetable or plant patch, as they feed on the leaves, flowers and fruits of many of our food plants. There are over 40,000 species of land snail, although only around 120 occur in Britain.  

There are several useful features for identifying the correct species. The overall shape, in terms of the ratio of height to breadth, is important, as species can vary between a wide, round, flattened shape to tall and thin. The shape, colouration and thickness of the mouth of the shell can often be used to discern between visually similar species. Shell colour and pattern of the shell can help. However, this can be varied between individuals of the same species. Empty shells can also have a different appearance than those with the snail inside. Other useful features can include the direction and number of whorls, shell thickness, surface sheen and texture. 

Very little equipment is needed for identifying snails, but a hand lens can help for smaller specimens, particularly when counting whorls or looking at shell textures. Specimen pots or trays can help you to safely store species while you study them, and forceps are useful for collecting and moving smaller, more delicate species.   

Garden Snail (Cornu aspersum)

Garden Snail on a leaf in a garden.

Distribution: Common throughout lowland Britain. 

What to look for: This is a well-known species that most people will have seen in their gardens or local green spaces. The garden snail has a thick shell, with a mottled brown, red, and yellow colouration. Its shell aperture is large and has a thickened white lip. It has around 4.5–5 whorls and its thick shell has a rough, wrinkled surface. The umbilicus, the depression or hole at the centre of shell whorls, often on the underside, is completely sealed by the lip. 

White-lipped Snail (Cepaea hortensis)

White-lipped snail by hedera.baltica, via flickr.

Distribution: Widespread across Britain, but mainly found in coastal areas in Scotland. 

What to look for: This species has a glossy, smooth shell that is usually a yellow colour. However, individuals can be pink, brown or red. The number and presence of dark spiral bands can vary but there is no more than five. This species most often has an obvious white lip around the shell aperture.  

Brown-lipped Snail (Cepaea nemoralis)

Distribution: Widespread across Britain apart from the northern parts of Scotland. 

What to look for: The colouration of this snail is widely variable and can be yellow, brown or pink. The presence of the banded patterning is also variable and they can have up to five bands across their shells. Their shells have between 4.5–5.5 whorls, with a semi-glossy surface. There is usually a dark rim to the lip of the shell aperture.   

Hairy Snail (Trochulus hispidus)

Distribution: Widespread throughout Britain. 

What to look for: This snail can vary in colour from cream to brown. It sometimes has a light band around the shell aperture. The shell is quite flat and densely covered in short hairs, which can be worn away over time. These hairs have been found to help the snail to adhere better to wet surfaces.  

Copse Snail (Arianta arbustorum) 

Heesterslak - Arianta arbustorum snail on concrete.
Heesterslak – Arianta arbustorum by Gertjan van Noord, via flickr.

Distribution: Widespread. 

What to look for: This species can grow up to 19mm. Its shell is a mottled brown with a thin band around the circumference, although its colour pattern can be highly variable. Its body is very dark and the shell aperture is a ‘C’ shape, often with a paler inside lip that can be bone-white. The shell has between 5–6 whorls and the umbilicus is a small crescent-shaped slit.  

Kentish Snail (Monacha cantiana)

Distribution: Widespread throughout England and Wales, less common in Scotland. 

What to look for: Between 15–22mm tall and 7–12mm wide, the shell of this species can range from very light amber to a darker orange-brown in colour. Its shell also has a very large final whorl. The body of this snail is a pale colour with two dark lines running along the top of its head, extending along its tentacles to its eyes. 

 

The NHBS Guide to UK Slug Identification

Slug is the common name for gastropod molluscs that have little to no shell. Descended from snails, they usually have a vestigial shell that is internalised, but some have either none at all or a very reduced one, such as the shelled slug (Testacella scutulum), which has a fingernail-like shell over its rear end. There are over 30 species of slug in the UK. 

As they do not have full-sized shells, they’re prone to desiccation, so many species are most active during and after wet weather and spend drier times hidden in damp places such as under man-made structures, tree bark, leaf litter and rocks. They play an essential role in the ecosystem, similarly to snails, by eating decaying matter such as plant material and fungi, aiding nutrient cycling.  

A small number of slugs are considered serious pests to agriculture and horticulture, eating foliage, fruits, and vegetables. This gave rise to the widespread use of toxic slug killing chemicals, which often impacted other non-target species. Recently, however, the use of iron phosphate baits has emerged, as they are less harmful to other wildlife.  

Black Slug (Arion ater) 

Arion ater. Large Black Slug, on grass.
Arion ater, Large Black Slug by gailhampshire, via flickr.

Distribution: Extremely common and widespread throughout Britain. 

What to look for: These species are large and vary widely in colour, including black, brown, grey, orange, reddish and green. It has long, coarse tubercles, the raised areas between the grooves on its skin, found on its side and back. Black slugs also have a pneumostome, a breathing hole, on the right side of their mantle, a protective structure of calcareous granules, through which they breathe.  

Common Garden slug (Arion distinctus)

Distribution: Widespread.  

What to look for: A dark or bluish-grey with dark lateral stripes and a pale yellow or orange sole (underside), with a characteristic yellow-orange mucus and no keel. This species also has tiny gold speckles on its tubercles, which are best seen through a hand lens. 

Netted slug (Deroceras reticulatum)

Distribution: Widespread. 

What to look for: This may be the most common slug across the UK. It is a pale, off-white colour, with a keel at the tip of its tail and a mantle that is roughly half the length of its body. It has a chunky build and the tubercles are pale than the rest of its skin, giving it a netted appearance.  

Western Dusky slug (Arion subfuscus) 

Slug sliding across a leaf from left to right.

Distribution: Widespread, but less common in East Anglia. 

What to look for: The dusky slug has various colour forms of yellow and brown. An important feature is the orange body mucus which stains on contact with your skin. It also usually has two dark lateral stripes and a pale sole with a fringe that blends in with the body.  

Hedgehog slug (Arion intermedius)

Distribution: Widespread but not common. 

What to look for: This is a small slug, at only 1522mm when extended, and is usually pale brown with a darker lateral stripe along its body to the mantle. Its sole is pale yellow and it has coarse tubercles that can contract to ragged points, giving it the reason for its name.  

Leopard slug (Limax maximus)

Distribution: Widespread. 

What to look for: The appearance of the leopard slug is quite variable but it usually has a pale background and distinctive dark spots and markings that resemble leopard spots. The markings on its back are usually arranged in three longitudinal bands and it has a pale sole.   

Yellow slug (Limax flavus)

Distribution: Found mainly in England and Wales. 

What to look for: The yellow slug is usually a bright, lemon yellow with darker markings, with blue tentacles and a yellow line along the keel which extends from the tail to approximately halfway along its body. This central line can sometimes be broken into dashes.  

Green Cellar Slug / Irish Yellow Slug (Limacus maculatus)

Rediscoveries and Recovery 

The Norfolk hawker dragonfly is no longer extinct, with the species set to be taken off the British Red List of endangered species after a large-scale population surge. Since its extinction in the Cambridgeshire Fens in the 1890s, the Norfolk Hawker’s small population has been restricted to the Norfolk Broads. However, in recent years they have been found in Kent, Hertfordshire, Sussex, Dorset and Devon due to an increase in suitable habitats across Britain resulting from climate breakdown. This has been the driving force behind the species recovery, however, the gaps in the current population distribution need filling to ensure the Norfolk Hawker’s long-term survival.?

A breeding population of an incredibly rare species of turtle has been discovered in India. The Cantor’s Giant Softshell Turtle is native to south and south-east Asia and has been classed as critically endangered. The discovery of a breeding female on the banks of the Chandragiri River in Kerala, however, provides hope for this illusive species. The study was led by a group of international conservationists who worked alongside local communities to record the first documentation of a female nest, and subsequently rescue the eggs from flooding. The hatchings have since been released into the river, and the team are now working closely with the local community to set up a hatchery and nursery near the original nesting site.?

Climate 

Since 2000, more than a third of Antarctica’s glacier anchors have reduced in size. These anchors, or “pinning points,” are important braking mechanisms that hold the glaciers in place and subsequently reduce the rate of ice detachment from the continent. New research conducted by the University of Edinburgh suggests that an increase in global sea temperatures is causing these points to thin at a much faster rate than previously estimated. Since 2000, 37% of pinning points have either shrunk or completely disappeared, and, as a result, the glacier’s braking force is weakening.?

The UK has had the wettest February on record, according to the Met Office. Between December 2023 and January 2024, the UK experienced 90% of the total expected winter rainfall. This increase in wet weather continued throughout February with some areas of the UK seeing two and a half times their normal rainfall for this month alone. These adverse weather conditions, a result of climate change, is having detrimental effects on farmers due to increased crop flooding, with some farms in Lincolnshire having been underwater since October. 

Science and Environment 

A 12mm long, transparent fish has been found to make a sound as loud as a pneumatic drill. Scientists in Berlin were studying the Danionella cerebrum in their lab when they began hearing strange clicking noises coming from the male fish in the tank. Upon investigation, they discovered that this miniscule species can make a sound of 108 decibels when measured at a distance of one metre away – this is roughly equivalent to the noise made by a bulldozer and is likely to be the volume at which other fish hear the sound. This noise is created by the contraction and release of the fish’s swim bladder, and it is one of the loudest noises ever discovered in a fish of this size.?

Ancient trees play an irreplaceable role in supporting forest life, according to experts. The results from a recent study in the Spanish Pyrenees show that ancient trees no longer exert energy on reproduction, and instead prioritise stress tolerance, durability and slower growth. It has also been revealed that, over time, sections of older trees die and decay, which allows them to host more diverse and greater quantities of different species than younger trees, as juveniles don’t possess the unique physical and physiological features to support them. Although the number of old growth trees continue to decline worldwide, researchers Munne-Bosch and Pasques hope their report will highlight the importance of our ancient trees’ ecological role.?

Policy 

The government are expected to announce a move to 100% badger culling under exceptional circumstances in the coming weeks. The current policy on badger culling aims to reduce badger numbers by 70% in each cull area, however the government may increase the target to 100% in certain circumstances, subject to consultation, as of January 2026. The Government had previously stated that the cull would end in 2025 and be replaced by increased badger vaccinations, however some fear that the new 100% cull policy may become standard practice instead.

Parliament has implemented the first EU nature law to restore 30% of the EU’s degraded ecosystems by 2030. This comes into effect after recent findings reveal that over 80% of all European habitats are in poor shape, and aims to ensure the restoration of 60% of these environments by 2040, and 90% by 2050. The EU has pledged that once these ecosystems are restored, they will ensure that the area does not significantly deteriorate once more in a bid to aid the long-term recovery of damaged natural areas. 

Author Q&A with Illustrator Mike Langman

Photograph of Mike Langman, nature illustrator, on a coastal path wearing a checked shirt, cap and with a camera around his neck.Mike Langman has been a full-time illustrator specialising in birds since 1992 and has published a total of 85 books, including Park and Garden Birds and the Guide to Ducks, Geese and Swans, with his work also featuring in many UK birdwatching magazines. 

Mike worked for the RSPB at their headquarters in Bedfordshire for nine years after finishing his education at Middlesex Art College in 1983, and his illustrations have been published in most of the RSPB’s quarterly Nature’s Home magazines, on nearly every RSPB reserve, on identification cards, in murals in information centre, and in other outlets across Britain and Europe.

He has been an avid birdwatcher from the age of ten and particularly enjoys birdwatching around his local area in the South West, especially Berry Head in Devon, with his knowledge and expertise regularly sought by local organisations. Mike is also a voluntary art editor for Devon Birds, his local bird society, where he has previously held a number of roles in numerous years between 1994 and 2010. 

Mike recently took the time out of his busy schedule to answer our questions about his career in illustration, which mediums he uses to create his drawings and more. 


How did you get into illustrating nature?  

A love of nature started with walks with my parents and visits to my grandparents one set keen on birds and the other owned a farm where I could (more or less) have free range to explore. Drawing wildlife came from copying pictures I saw in books of wildlife that excited me, initially big cats but as I watched birds in gardens and countryside I would copy pictures from books of them too. 

What are your favourite mediums for illustrating books?  

Most of my published work is a mixture of watercolour for its freshness and clarity, but to speed up the process I (like many other published artists) use gouache too, this being opaque pale paint that can be put on top of darker watercolour to create feather edges and highlights etc. A watercolour purist uses the white of the paper to shine through pale areas!

How do you approach illustrating a bird you’ve perhaps never seen in real life?  

I use whatever I can get my hands on, googling photos or videos (better for capturing character), but I still use skins (dead crudely stuffed birds) held in museums like Tring or even Exeter and Torquay. 

How do you record a birds behaviours, and have you seen any unusual behaviours from a common bird? 

Yes, as a birder I’m always looking for not just unusual species but behaviours too an inquisitive mind leads to a better understanding of the species and I do illustrate behaviour in published work when required to.  

What has been your favourite bird to illustrate that you keep coming back to?  

That’s a tricky one, but I love seabirds and warblers. I suppose if I had to choose one its the Firecrest for its character and colour a truly stunning tiny bird. But, I must not forget our south Devon speciality, the Cirl Bunting, and, and I could go on!

How has climate change altered your approach to projects? 

I do a huge amount of illustration work from home but I do travel a bit too (although much more locally based than I used to be). At home I’m trying to be as carbon neutral as possible with solar panels, storage batteries, good house insulation and, last year, buying an electric car. When I do travel abroad I do as much wildlife watching as possible visiting reserves and hiring guides which will help maintain some of the very important and often not so important biologically rich areas. 

Do you see wildlife human conflict in your work? 

Not so much in the publishing world, but as part of my secondary job as a wildlife guide here in Devon, running walks, tours and cruises, I have witnessed some terrible scenes. Dolphins caught in nets, seals with plastic rings and fishing gear snagged around their necks, jet skis harassing dolphins, fishermen throwing rocks at seals and even fishermen having ‘fun’ catching gulls with baited hooks. Away from the sea we have hedges cut by land owners at the wrong times of year, and housing developments on green land around Torbay in areas I used to watch wildlife...

What bird do you wish you had seen and why? 

Pretty much every bird I haven’t seen but I know that’s not a good thing, practically and in terms of harm to my carbon footprint, and inevitably it’s just not possible. So, I keep it local and look for anything that provides me with a challenge to find, identify and share with others. For more than 30 years I’ve wanted to find a Hume’s Warbler (a small and very rare eastern Siberian migrant) at my local lakes at Clennon Valley in Paignton (where I volunteer as part of the friends group). In December 2023 I did a double take when I heard one calling, ‘Che-wee, Che-wee’. Eventually after what seemed like an eternity I located and watched it, sketched it and shared the sightings immediately with others. The bird stayed around for over a week. I guess I need a new goal now… 

What projects are you working on right now? 

I’ve just finished the 3rd edition of the Helm Field Guide to the birds of the Middle East and painted its new cover too, which I’m very proud of. I’m also working on some wood etching images (my work completed on the computer!) for Greenspace designs for the Lower Otter Restoration Project.

Author Q&A with Hugh Warwick: Cull of the Wild

Cull of the Wild cover showing a red squirrel on the right facing a grey squirrel on the left, with a blue sticker on the cover saying 'signed copies.'In Cull of the Wild, author Hugh Warwick investigates the ethical and practical challenges of managing invasive species to increase biodiversity. He explores the complicated history of species control over time, while also combining scientific theory and subtle humour, to explain the many issues conservationists face when trying to protect native species from their non-native rivals.

Hugh Warwick, author of Cull of the Wild, in a black and white photo wearing a shirt and gilet.Hugh Warwick is an ecologist, conservationist and writer who specialises in the study of hedgehogs. He has published three books focusing on this species, however he recently expanded his field of study to include invasive species while writing Cull of the Wild. He has previously written for BBC Wildlife, New Scientist, The Guardian and The Daily Telegraph, is the spokesperson for the Hedgehog Preservation Society, runs courses on both hedgehog conservation, and lectures in creative writing.

Hugh recently took the time to talk to us about his book, including what inspired him to write Cull of the Wild, how he hopes his book will help future conservation methods, and more.


Firstly, what inspired you to write a book on the culling of invasive species?

The very first independent field work I did in 1986 – for the 3rd year project of my degree – took me to North Ronaldsay. My supervisor had a friend who was both the GP and the bird warden on this island, the most northerly in Orkney. He had noted that there seemed to be a correlation between the increase in number of imported hedgehogs (that was the postman’s fault!) and the decrease in breeding success of ground nesting birds – in particular the Arctic Terns. My work was to try and find out how many hedgehogs there were. This turned out to be around 500 – not the 10,000 the Daily Express had reported! The bird observatory organised an airlift to remove the hedgehogs after I had gone and I returned in 1991 to repeat the survey. Since then I have found the collision of ecological study with human concerns really fascinating.  

This led me to become involved, rather inevitably, in the Uist hedgehog saga, where the RSPB and Nature Scotland were killing the hedgehogs for the very same reason they had been airlifted from North Ronaldsay. I quickly shifted from reporting on the story for BBC Radio 4, to joining the campaign against the cull, and then doing the research that helped stop it. But while all this was happening, I met a researcher from New Zealand who was telling me that they were killing hedgehogs over there (in the 1860s we sent a load of hogs over to help the colonialists feel more at home) I could see no reason not to kill those hedgehogs.  

That apparent contradiction has been spinning in my head ever since and was the springboard for this book.

How did you find researching such differing opinions on the subject, and have your preconceived opinions changed over the course of writing this book? 

I found this book so very different from all the others I have written. Previous outings have always been with people who are just really pleased to talk – to share their enthusiasm for Beavers or Water Voles or owls. This was the first time where I felt like the initial communication was almost like a job interview – assessing whether I was suitable to talk to. Some people simply refused to talk, others were cagey. I guess I was quite naïve! 

The journey of the book is basically one where my head and my heart are in constant debate. I lay out my ‘bunny-hugging’ prejudices at the start. I suppose I was hoping to find that all instances where animals were being killed could be dealt with in other ways.  

One of the biggest lessons I learnt, though, was about how people, even ones with whom you have fundamental differences of opinion, share so much common ground. But you will never see that common ground if you charge in at the difference! I love that one of my potentially conflicting interviews ended up with the biggest argument being over who recorded the best version of Sibelius’ 5th Symphony! 

In Chapter 1, you discussed that animals are shown to be continually developing to become more like humans – problem solving, making and using tools etc. Do you think this gradual form of humanisation may lead to more equal ‘rights’ between animal species and humans in relation to killing for conservation?

I would not look at this as humanisation – that is slipping back into the human exceptionalism that got us into this mess. Currently the degrees of cruelty we deliver to wildlife is arbitrary, based in large part on language and on the names we give them, even different members of the same species. 

We need to recognise that these animals being killed experience pain, joy, fear and hope. If the realisation that different species have the capacity to do human-like things is enough to get this recognised, then that is some progress.  

I have been gently eased away from the concept of ‘rights’ for animals and towards a desire to see cruelty minimised. Rights are important and I see their value – but here, I feel the best outcomes will emerge from a utilitarian desire to maximise good and minimise bad. Though that requires we have the idea that these animals, most of whom are simply in the wrong place at the wrong time, are individuals and can suffer.

You must have visited many places and spoken to many different people about different species while you were writing this book. Were there any particularly memorable moments or experiences that that have stayed with you?

I did not get to some of the places in this book – time, Covid, money and a desire to minimise flying all conspired to keep the exotic interviews on Zoom. But the adventures I did have were all special.  

Heading out along the coastline of South Ronaldsay, Orkney, with Spud – the most handsome labrador I have ever met – was magical. The wind blew, the surf crumped in from the Atlantic, and Spud, well, he followed his nose and we followed him as he tracked down evidence of Stoats.  

The Stoat story is so important – it is about speed and trying catch this problem early – they were only found in 2011. But more than the practical, it is also about the buy-in of the local population. If the public are not onside, the conservationists can give up now. So it is about education and communication as much as it is about deciding which traps to use and where to site them.

In what way do you hope that Cull of the Wild will help future animal conservation efforts?

The overarching message I hope people get from Cull of the Wild is that ecology is both fascinating and VERY challenging when it is part of a conflict. Ecology is not given the level of respect that it should receive. It is always sidelined – economics and politics hog the headlines – yet both of those are but subsets of the wider ecosystem. Without a healthy ecosystem we are on a downward slope to disaster. So, I hope that people will read this book, maybe because they are outraged at the killing, and will then come away realising that ecology is very complex and should be treated with great respect.  

I also hope that this book will convince people who hold very firm opinions – opinions that are often amplified by the bubbles in which we tend to linger – that people with differing views may well share many of the same values as themselves. And that to begin discussion at the common ground is the foundation of progress. Argument should not be about winning, but about making things better. Remember, it is quite possible that some of the things you know are wrong. A friend of mine turned up at a conference recently with a t-shirt saying ‘Don’t believe everything you think’. We should be humble enough to recognise we might be wrong.  

Are you currently working on any other projects that you can tell us about?

As I write this, the lovely people at the publishers Graffeg are hoping I will stop promoting Cull of the Wild and finish the two books I owe them: one on bats and the other on nocturnal nature. I have another narrative nonfiction brewing – about as different to this book as imaginable. Something which will hopefully bring laughter into our love of nature.

Book Review: Of Cockroaches and Crickets

***** An amusing and light read

Of all the insects that have a PR problem, cockroaches must rank very high. That, however, did not stop German entomologist, journalist, and filmmaker Frank Nischk from spending a year-long internship studying them. In this book, he regales the reader with stories of his time in the lab and the field studying first cockroaches and later crickets. A light and breezy read despite the serious undercurrent of biodiversity decline, Of Cockroaches and Crickets turned out to be an entertaining read.

This book was originally published in German in 2020 as Die fabelhafte Welt der fiesen Tiere by Ludwig Buchverlag and has been translated into English by Jane Billinghurst who frequently works with Greystone Books. Carl Safina contributes a short foreword that cracked me up and immediately set the tone. The book is effectively a memoir of Nischk’s early years studying for his undergraduate and doctorate degrees in the mid-nineties, told in 18 short chapters in two parts. His subsequent career pivot to documentary filmmaking only receives passing mention.

Given Nischk’s concern about biodiversity decline, and his desire to communicate to a broad audience why insects are fascinating and important, there is an irony to his undergraduate internship. He spent a year in the lab of Martin Dambach studying the aggregation behaviour of the German cockroach, Blattella germanica. By day, large groups of them bed down on their own excrement, likely attracted by pheromones released by the faeces. The irony? Nischk’s internship was funded by biotechnology giant Bayer which was hoping to isolate the chemicals responsible for putting the cockroaches in sleep mode to develop a pheromone-based cockroach trap: “the exterminator’s holy grail” (p. 25).

For his subsequent doctoral studies, Nischk got his conservation priorities in order. Staying with Dambach, he turned to crickets and spent time in Ecuador recording their songs. Next to discovering species new to science, this is his entry into the fascinating field of soundscape ecology or ecoacoustics. A small cadre of ecologists has been recording soundscapes of natural habitats. Bernie Krause (not mentioned here) is one particularly well-known example. By comparing recordings made years or decades apart they have shown how natural soundscapes are changing and often disappearing due to human encroachment. Others are hoping to train software to analyze recordings and identify species by their calls. If scaled up, the dream is to have passive acoustic monitoring stations in biodiversity hotspots around the globe.

This backbone of his research is livened up with personal anecdotes and interesting asides. A friend’s call about a wasp infestation in her kitchen drawer is an excuse to introduce the 18th-century French entomologist Jean-Henri Fabre who was one of the first European naturalists to systematically collect and study butterflies, beetles, and wasps. Getting stung by a bullet ant in the rainforest of Ecuador leads to an aside about the late entomologist Justin O. Schmidt, the man who got stung for science (and wrote a fine book about it too). Tracking down a particularly loud cricket in Ecuador is the starting point for an unusual case where entomologists helped to defuse international political tensions between the USA and Cuba (this story has a surprising twist that I will not spoil here). A botched attempt to eradicate cockroaches that escape his experimental setup backfires most spectacularly, while fieldwork in the tropics is always fodder for amusing cultural misunderstandings and sober reflections. There is a nice mix here that never dwells on any one topic too long and makes for a book that is hard to put down.

The third and final part is, perhaps surprisingly, comparatively the weakest of the book. In four chapters Nischk muses on the biodiversity crisis, particularly the still poorly understood decline of insects, and discusses examples of individuals and organisations who are creating and protecting wildlife habitat. Probably most interesting are the little-known grassroots initiatives in Ecuador that are undertaken by villagers and farmers turning to ecotourism. But is this really the answer? Or does it merely perpetuate the idea that nature can only be protected if it has monetary value? You will not find a critical or comprehensive analysis of wildlife conservation here. There is also an odd focus on projects in the USA, e.g. the High Line in New York, the Xerces Society, Joan Maloof’s Old-Growth Forest Network, and the Yellowstone to Yukon Conservation Initiative. I wonder if this was added for the English translation. There is no mention of e.g. the European Natura 2000 network of protected areas or E.O. Wilson’s bold call to protect half the planet, and only passing mention of the German environmental organisation NABU or the practice of rewilding. Putting aside such nitpicking, none of this takes away from his genuine concern about the ongoing loss of biodiversity nor from his conclusion that the key to protecting species is protecting their habitat.

Overall, Of Cockroaches and Crickets is an amusing and light read that I devoured in a day. Nischk offers a nicely balanced blend of interesting natural history, amusing personal stories, and captivating scientific research. Whether it is flies, wasps, or rats, we need more books that celebrate those species we all too readily dismiss as pests.

Author Q&A with Chantal Lyons: Groundbreakers

Groundbreakers jacket showing a wild boar drawing on top of a green background.Big, messy and mysterious – crossing paths with a Wild Boar can conjure fear and joy in equal measure. In Groundbreakers, Chantal Lyons gets up close and personal with this complex and intelligent species in the Forest of Dean, and investigates the people across Britain and beyond who celebrate the presence of these animals – or want them gone. From Toulouse and Barcelona where they are growing in number and boldness, to the woods of Kent and Sussex where they are fading away, to Inverness-shire where rewilders welcome them, join Chantal on a journey of discovery as she reveals what it might take for us to coexist with the magnificent Wild Boar. 

Chantal Lyons, author or Groundbreakers, stood against a tree.Chantal Lyons is a naturalist, writer and science communicator. Having grown up in the tidy countryside of Kent, her encounters with the growing rewilding movement opened her eyes to the potential for restoring nature in Britain, and inspired her to study the relations between people and Wild Boar in the Forest of Dean. She currently lives in Cheltenham, never too far from the boar. 

Chantal recently took time out of her busy schedule to tell us about her first experience with a Wild Boar, her hopes and fears for the future of their populations in Britain, and more.


First of all, could you tell us a little bit about yourself and what led you to writing a book about Wild Boar in Britain? 

Up until my mid-twenties I spent all my writing time churning out unpublishable fantasy and sci-fi novels, alongside a zig-zagging career in the charity sector. The journey to Groundbreakers was perhaps a ponderous one – it started when I went to the Forest of Dean in summer 2014 to research a Masters dissertation in environmental social science. The Forest of Dean was, and still is, one of the few places in the country where Wild Boar have returned since their extirpation from Britain around 700 years ago. I wanted to find out from local residents what it was like to suddenly find yourself living alongside a big, wild, and utterly unfamiliar creature. What I discovered from those interviews astounded me, and I was sure that some established nature writer would soon publish a book about the return of boar to Britain and what this meant for us. No one did. After seven years, I decided to send off a proposal to a publisher who I’d encountered on Twitter, and it snowballed from there. 

Could you tell us about your first real life experience with a Wild Boar? 

It was a long time in coming! While I was in the Forest of Dean doing the Masters research, I used every spare moment to explore the woods on my own, often following locals’ leads. It always came to nothing. The boar seem to be like cats – you seem to be more likely to meet them the less you want to. But eventually, at the tail end of summer, I went to a spot where I’d heard from someone that a sounder (a family group of boar, which is always led by a matriarch) had been foraging each evening. I heard them softly calling to each other, then there was a rustling in the bracken, and an adult stepped out onto the path to get a look at me. We stared at each other for about two seconds, she gave a belching alarm call, and then she vanished with her family.

I appreciated the ways in which you speak about rewilding, in particular the importance of nuance and accepting the unknown. Do you think that uncertainties about the best way to undergo reintroduction projects and their expected outcomes are a significant hindrance to their implementation? 

I have heard many a time from rewilding practitioners that the inherent uncertainties in rewilding can make it especially challenging to gain funding, given that projects aimed at restoring nature have traditionally been expected to be able to set clear targets and end-goals. But beyond practicalities like money, I think the bigger challenge is the attitude that reintroducing species for rewilding purposes is too big an unknown, and therefore too big a risk. Of course we should aim to conduct as much scientific research and gather as much knowledge as possible, but we are running out of time to reverse the haemorrhaging of our biodiversity in Britain and globally. To me, it beggars belief that we seem quite happy to continue doing all kinds of things that we know are massively damaging the environment, but reintroducing species? Why, that’s a step too far!

One part of the book that particularly resonated with me was in ‘The Risks of Being Alive’ where you speak about how, for most modern humans, ‘nothing matters more in life than eliminating all risk to it – even at the cost of happiness’. What do you think it would take for humans to accept more wildness into their lives? 

Maybe it’s a cliché to say this, but I think it hugely helps to engage children with nature from a young age, and to continue doing so as they grow up. That of course means ensuring that everyone can access nature. 

Beyond that, the question of how to convince people to accept more wildness is an incredibly tricky one, especially in a place like Britain which suffers so badly from ‘ecological tidiness disorder’ (as Benedict Macdonald puts it in Rebirding). The problem is that most of us have not made the connection between our tidy sterilised surroundings and the loss of nature. There is a lack of understanding that the majestically bare plains of Dartmoor or our rolling green fields mean an absence of life; and that you need all manner of species, including big ones, to ensure healthy ecosystems. I didn’t realise this for years. But once you know, you can’t stop wanting to bang the drum. 

What are your biggest hopes and worst fears for the future of Wild Boar populations in Britain? 

I want the planned, country-wide reintroduction of Wild Boar to become accepted both politically and societally. In the meantime, I hope that the few boar we do have are allowed to thrive. That means more oversight of people carrying out legal shooting of them on their land, and – in the case of the Forest of Dean population – better censusing methods to ensure they are not over-culled (though some culling will always be needed, as the boar currently lack other predators). 

What am I most afraid of? That very soon, a disease called African Swine Fever (ASF) which burns through pig populations like wildfire will make its way into Britain. Since Brexit, border controls on pork imports have been so lax that experts think it’s only a matter of time before ASF reaches us. Forestry England is primed to wipe out every last boar in the Forest of Dean if the disease is ever detected in the population. And once they’re gone, it seems very unlikely that they would ever be reintroduced (legally or illegally) again. We will miss a miraculous chance to kickstart the landscape-scale restoration of nature in Britain.

Finally, what is occupying your time at the moment? Are there plans for further books in the pipeline? 

I work full-time as a science communicator, which does narrow my research and writing windows! But I am currently working on a proposal for book number two. It’s intended to be something of an evolution of Groundbreakers, picking up a thread that often emerged during my research interviews with people, but which I couldn’t possibly have fitted into this first book…
