Equipment in Focus: Professional Hand Nets

Designed and manufactured by NHBS, the professional hand net is a
popular net choice for pond dipping and kick sampling. It is lightweight,
durable and practical, and used by universities and professional
institutions.

The professional hand net is available with a wide variety of mesh sizes and two net depths: standard and deep. The frame and net bags can be bought separately, allowing you to customise your hand net depending on your requirements. The standard outer frame width is 250mm and other 200mm and 300mm wide versions are available. The hand net can also be bought with two- or three-part collapsible frames to allow for ease of transport.

The sturdy metal frame is manufactured using marine-grade aluminium with an inner brass frame for net bag attachment, granting considerable resistance to wear and tear in the field.

Both aluminium and wooden handles are available, the benefits of the wooden handle being that it floats and is comfortable to use in colder conditions.

Net and mesh sizes

Mesh sizes range from 53µm up to 2mm. Net bags are also available in both standard (30cm) and deep (50cm) sizes.

For extra durability small mesh sizes are made from precision welded nylon material and the 1mm and 2mm mesh bags are made from woven polyester material.

The 1mm mesh is the most commonly used size for aquatic and kick sampling and the 2mm is more suited for amphibian surveys. Smaller precision meshes can be used for sampling smaller organisms such as plankton and chironomids.

Changing nets

Net bags can be attached and detached from the frame so that multiple nets can be used with a single frame. This can be handy for washing and replacing nets or when using different net meshes for sampling different organisms.

To demonstrate how to attach a net to the hand net frame, we have gone step by step through this process.

Steps

Begin by removing the inner brass frame from the outer aluminium frame by undoing the set screws from the outside of the frame using an allen key or use a spanner to loosen the nuts on the inside of the frame.

After removing the nuts, set screws and plastic clips, slide the net bag onto the now free inner brass frame using the slots in the orange section of the bag. Ensure the two upper slots are positioned just below the corners of the frame. It may be preferable to remove the plastic tube that connects the ends of the inner frame before feeding the frame into the net bag and reconnecting it.

The plastic clips can now be clipped onto the brass frame in the slots of the net bag. Ensure the flat side of the clip is facing the outside.

Place the clip flush against the hole in the outer metal frame and insert the set screw through the hole in the clip and the frame. The holes in the outer frame are off-centred, so ensure the holes are nearer to you when fixing the clips to allow the brass inner frame to sit flush with the edge of the outer frame.

The nut should then be loosely tightened onto the set screw using a spanner or by holding the nut in place and using an allen key on the set screw.

Loosely tighten the other three nuts and ensure the inner frame is positioned correctly before fully tightening. The clips holding the brass frame should now be firmly fixed against the outer frame.

With the net bag now securely attached to the metal frame, the professional hand net can now be used in the field.

Replacement and related equipment

Our nylon Professional Hand Net Cover will help to protect and improve the longevity of the net, and is ideal for safe storage and transportation.

Replacements are available for the hand net fixings and the inner frame.

Extension pieces are also available for use with both the two- and three-part collapsible frames to allow for net extension. Extra joining ferrules are available too.

NHBS supplies a variety of specimen pots for storage and viewing of collected samples.

Author interview with Michael Stephen Clark: The Fragmented World of the Mongoose Lemur

The Fragmented World of the Mongoose Lemur is a book about a critically-endangered species, fractured ecosystems and the global war on nature. It is a compelling story in which author Michael Stephen Clark reveals the fundamental paradox of the mongoose lemur’s natural history.

In this post we chat to the author of this important and timely book about his work with mongoose lemurs, the problems withthe way that conservation is reported in the mainstream media and his hopes for the future given the alarming loss of biodiversity and rate of extinctions we are currently experiencing.


Author Michael Stephen Clark

Your book is described as a modern natural history, but it also conveys a larger message that is of relevance to our relationship with all wild species. Why did you choose the mongoose lemur as your focal species – what is it about this primate that makes it suitable for illustrating more widespread issues?

I first became interested in the mongoose lemur when I worked with an aged and overweight pair at London Zoo in the 1980s and 1990s. They were being kept off-exhibit, which I thought was inappropriate given their endangered status. In due course, we were able to move them into a larger, outdoor enclosure, but only after an operation had been performed on both of them to remove excess adipose tissue. It was all very invasive, but the animals were much fitter, healthier and happier as a result. Shortly afterwards, I discovered that the captive breeding programme for the species lacked co-ordination, so I established the first international studbook for the species in captivity. There wasn’t a great deal of information about them in the literature and relatively few researchers and institutions had sought to remedy that. It quickly became clear to me that the mongoose lemur was fast becoming undervalued and potentially overlooked as an endangered species. I’ve been concerned about them ever since, probably because my sympathies often lie with the ‘underdog’.

I’d long been aware that the mongoose lemur could illustrate very directly the profound disruption caused by human alteration of the natural continuum. Human attitudes to wildlife contain a raft of contradictions that result in contradictory outcomes. This is particularly true of the mongoose lemur. In common with virtually all lemurs, it is a critically endangered species that exists in compromised and/or fragmented habitat in the wild. Perversely, however, it appears (on the surface) to be more numerous and relatively safe as a naturalised alien species on the Comoros Islands of Anjouan and Moheli. Lemurs in captivity are generally viewed as a conservation priority, yet the mongoose lemur ranks lower in importance than some of the more enigmatic lemur species. Already, without digging too deeply, we can see that the mongoose lemur has experienced displacement at every point where it has come into contact with humanity.

Perhaps, more alarmingly, the mongoose lemur has unwittingly become a prima-facie example of something disquieting; namely, a growing acceptance that nature will be allowed to persist only in places of our choosing. It’s a situation that has led to questionable decisions around relocation, translocation, restoration, rewilding, and re-introduction. To my mind, these things invite compromise, not least where species such as ring-necked parakeets in England and mongoose lemurs on Anjouan are inter-changeably considered wild, free-living, native and/or naturalised. These compromises ominously signpost natural systems by human design. Presently, the momentum is behind stand-alone programmes, projects and initiatives that are, of necessity, limited in scale. This may well lead to the ultimate breakup of biodiversity and an end-point where our natural world has become little more than a ‘zoo in the wild’.

Do you think that the way conservation and the plight of endangered species are reported by the mainstream media is problematic? I’m thinking, for example, in terms of how the public, conservationists and governing bodies might go on to perceive the state of the natural world as a result?

I actually think it’s a massive problem for conservation. Once upon a time, the adage was ‘there’s no such thing as bad publicity.’ In recent years, the mainstream media has shifted away from the substantial to the superficial reporting of wildlife conservation matters. Social media and the wider online milieu all feed into that, of course, but far too many stories are either half-told, poorly-told, or just plain misleading. It’s actually worse than not telling the story at all. This is especially disruptive for governing bodies and NGOs that can so easily find themselves painted into a corner by media-generated hubris. I’m not sure that a proliferation of conservation news portals, websites, blogs, podcasts and influencers is useful either. It is more likely that conservation stories will become even more distorted, diluted and diffuse as result.

I think the effect of all this on the public, among conservationists, and within governing bodies is potentially quite dangerous. It could make identifying priorities and taking effective action a minefield of conflicting imperatives. The recurring controversy over the Ramsar site at Coul Links in Scotland is a good example of media hubris threatening not only to drown out voices of reason, but also to trample the letter of the law into the ground. It took the combined firepower of a self-generated media campaign by a coalition of Wildlife Trusts and NGOs to beat back an existential threat to unique (and legally protected) dune habitat. I suspect that such coalitions will have to establish permanent media entities if they are to fight the war on nature across several (media) fronts.

Given the alarming rate of extinctions and global diversity decline, what would you like to see happen, both on a local and an international scale, to begin dealing with this? And would you describe yourself as broadly hopeful or pessimistic about this crisis?

I’m afraid that I am neither optimistic nor pessimistic about the future. I know it’s a cliché, but I think the future is already here. The important decisions now (as ever) will lie with young people, many of whom are not only well-educated and eminently qualified, but savvy as well. I recently rejoined Linkedin after a long absence and the sheer number of extremely active, professional wildlife conservationists around the world is really quite dazzling. In the short-term, issues around job security, personal security, career development, and establishing substantial permanent facilities in the field need to be addressed.

Frankly, I think that’s primarily the top-down responsibility of pan-national institutions such UNEP and the World Bank. The scale of accelerated extinction events forewarns us of a looming biodiversity crisis that could very easily become an existential threat in just a couple of generations. It requires a global response and the money really has to start flowing from global institutions if we are to empower and support our highly motivated international conservation professionals. To my mind, food security, health, climate, biodiversity and species conservation are equal priorities. I don’t understand how this became a hierarchy of aspirational goals because the response they all require is equally urgent.

In the medium term, it is not news to say that we have to invest in future generations, but ‘hope and inspiration’ aren’t enough. I think that young children generally receive a good grounding in natural history in their pre-school and primary school years. With a little support, that can happen in a developing country as easily as it can in the UK. But, young people need to have pathways they can follow in order to learn more. From there, they can gain a rounded understanding of natural history, which would inevitably include an elementary form of conservation biology. I’m a bit surprised that some of the more prominent NGOs aren’t lobbying for this with a draft curriculum. Nature conservation education for school-age children has to graduate from photocopied fact-sheets and elevate itself as the most valuable ‘eco-system service’ available.

As a zoological professional you have studied and worked in several esteemed organisations including the University of Bristol, London Zoo and Oxford-Brookes University. What do you consider to be the most significant highlights of your career so far?

Anyone who has ‘hands-on’ experience of working with wild animals in the field and/or captivity will tell you it’s a life full of great highs and lows. It doesn’t do to dwell on the lows so I’ll concentrate on things that I considered achievements. As I explain in my book, the time I spent on Anjouan in the Comoros Islands was a very special career highlight. It was a great privilege to be trusted with the capture and care of Pteropus livingstonii, one of the rarest bat species in the world and, of course, to encounter free-living mongoose lemurs first-hand. I’m especially gratified that several papers, features and articles that I authored or co-authored were published in the course of my work at the Zoological Society of London. These included my account of mongoose lemurs on Anjouan, the jointly written history of black-footed penguins at London Zoo, and a report on breeding Leadbeater’s Possum at London Zoo. Getting up close and personal with urban foxes and badgers in the course of fieldwork for Professor Stephen Harris at Bristol University was memorable, and I very much enjoyed my brief role as a visiting lecturer at Oxford-Brookes University. It was quite an honour to be there at the beginning of the now prestigious Primate Conservation MSc course.

The Fragmented World of the Mongoose Lemur is, in large part, a species-specific natural history – a format that is perhaps less popular than it has been in previous years and decades. The book was also published independently. How did you find the process of planning, writing and publishing the book and what were the main challenges you faced?

It’s correct that the species-specific natural history books have fallen out of favour with mainstream publishers, but I’m not convinced that readers feel the same way. In (apparently) normal circumstances, the life history of a species will appear to be relatively constant. In natural history classics such as David Lack’s ‘Life of the Robin’ and Sarah Churchfield’s ‘Natural History of Shrews’, the subjects live in a self-contained world that is full of challenges, yet seems immutable. The world today, in the age of the Anthropocene, rarely allows for ‘normal circumstances’. Wild animals will live, prosper, suffer, die or become extinct largely at our discretion, which means that their life histories now have to take account of the rapid, ongoing changes wrought by hyper-accelerated, unregulated human activity. That’s why I think it’s valid to revisit species-specific natural history writing and place it in a much wider context.

There was a time when my book would have been titled ‘The Mongoose Lemur in its World’, but that world no longer exists. It more accurately lives in a fragmented world of our making. This is happening to species the world over and those that are able to adjust may live, while those that can’t will surely disappear. We need to understand what makes the difference between the two potential outcomes in order to construct a meaningful response. I think this can emerge from species-specific natural histories that draw from a deeper well of scientific, philosophical and practical resources. I think it’s too often wrongly (and condescendingly) assumed that readers either can’t or won’t respond to stories that cast the net widely and speculate, as I have done, about ‘Propects and Perspectives’.

I’m fairly comfortable now with the process of independent publishing and I’ve never seen it as a poor relation to using an established publishing house. I would describe it as a slow, gentle learning curve rather than a steep and arduous one. The early stages of planning and writing are the most fun, but luckily I quite like editing, proofing and polishing too. I’m quite experienced in that regard but I find that editing your own work means that you really can’t rush it. Familiarity breeds oversight. I usually keep sharing with others to a minimum, but for this book I got a lot of help on specific chapters. I needed it too, and their input was invaluable as the acknowledgements section of the book will attest.

If I had to identify a single challenge that was really testing, I would say that maintaining a consistent, balanced style of writing throughout gave me the most sleepless nights. I wanted to hold the reader’s interest with an engaging narrative but still maintain a firm grip of the factual material. I also wanted the book to be a bit provocative. I always think I’ve read a good book if it leaves me with as many questions as it does answers.

Finally, what is in store for you next? Do you have plans for further publications?

At the moment, I’m doing the preparatory work for events in support of the book. I’ll be using my original colour slide transparencies from Anjouan to illustrate my presentations and I recently bought a very old colour slide projector for that purpose. It’s a bit quirky, I know, but I think it will make things a bit more interesting.

In terms of writing and publishing, I have a couple of things of my own in development, but I’d be interested in collaborating with others to produce further modern natural histories. I’d like to keep the focus on primates, mainly because they’re exposed to lots of different pressures in a variety of situations where they come into close contact with us humans. Their stories challenge us to think about the relationships we have with nature generally and how we are going to rescue biodiversity from our worst excesses. Species such as pygmy slow loris, Cat Ba langurs and Kirk’s red colobus spring to mind, although there are countless others.

Print-on-demand and increasingly accessible typesetting software mean that there are few obstacles to producing books like this. If there is a problem then it is persuading authors to enter a publishing relationship that is unconventional, yet fairer and more equable than the conventional model. Publishing independently also means that your book need never go out of print, something that frustrates many published writers who find themselves out of contract.

This Week in Biodiversity News – 3rd October 2022

Climate Change

As global temperatures rise due to climate change, blue lakes in North America and Europe are likely to turn from blue to green-brown. This is mainly due to changes in algal blooms and sediments which are affected by temperature and precipitation. As well as the purely aesthetic impacts on local culture and recreation, there are important implications for water quality, particularly for lakes that are used as drinking water sources.

Termites by Aleksey Gnilenkov via Flickr.

An international study looking at the future role of termites in ecosystems has determined that their role could be much larger in a warming environment. These wood-consuming insects are important for breaking down wood and contributing to the earth’s carbon cycle, but their activities are currently concentrated mainly in the tropics. With an increase in global temperatures, they are likely to expand their ranges much further north and south.

On September 18th 2022, the Arctic reached its annual minimum extent, covering an area of 1.8 million square miles. This is approximately 598,000 square miles below the 1981-2010 average minimum. Since measuring began in 1978, the amount of summer ice in the Arctic has declined significantly and 2022 was tied with 2017 and 2018 for 10th lowest in 44 years of observations.

Research

Growing hedges and perennial flower strips around intensively-farmed orchards has proven to be effective in providing wild bees with continuous forage over the growing season. The study, which was conducted by researchers at the University of Freiburg, found that the variation in flowering times of the hedgerows and flower strips meant that bee diversity and abundance were both improved.

Researchers from Hokkaido University have been using the fundamentals of chaos theory to study the behaviour of electronically tagged narwhals. In doing so, they have detected interesting patterns in what was previously assumed to be completely irregular diving and resting behaviours. It is hoped that this novel technique might be useful in assessing challenges to narwhals relating to climate change and loss of sea ice.

A study looking at the impacts of the Covid-19 lockdowns on the natural world, and recently published in Proceedings of the Royal Society B, has found that different bird species were affected in different ways. Many that were previously frequent visitors to parks and gardens were found to visit them less, as these spaces were increasingly occupied by people and their pets. Scavengers, however, such as gulls and corvids, were more likely to benefit from the change in human behaviour, feeding on the increased food waste that was left behind.

Conservation

A new Welsh Agriculture Bill was laid before the Senedd last week which would see Welsh farmers being paid to help to protect nature and fight climate change. Currently, farmers receive a share of public funding based largely on the amount of land they have. In the future, payments could depend on conservation work such as planting trees, restoring peat bogs and other essential habitats as well as utilising more sustainable farming methods.

A new study has shown that red kite chicks born during droughts, such as that of 2022 in England and Wales, often show permanent developmental damage which can make them smaller, more vulnerable to disease and less capable of hunting as adults. Although widely considered a conservation success story, this new research has led to concerns about the future of red kites in a continually warming environment.

An updated Wildlife Comeback Report, commissioned by Rewilding Europe and published on 27th September, highlights the species that have made a comeback in Europe over the last four to five decades, and explores the situations that have allowed this to become possible. The report hopes to show that, given measures such as effective legal protection, improvement and connection of habitats, and dedicated species recovery and introductions, wildlife can both return and thrive.

The Sussex Bat Group and Vincent Wildlife Trust are working together in an urgent attempt to save a colony of endangered greater horseshoe bats discovered in West Sussex. The barn in which they live is in urgent need of repair – work which needs to be undertaken during the winter while the bats are hibernating in nearby caves. An appeal to raise £200,000 has been launched to cover the cost of the work.

New regulations introduced in the Republic of Ireland mean that basking sharks are now provided with special protection. As a result, it is now an offence to hunt or injure a basking shark, as well as interfere with or destroy its breeding or resting places. One of the largest species of shark, the basking shark is globally-threatened and faces a high risk of extinction.

On Saturday 1st October, new laws came into force which mean that beavers are now officially recognised as a native species in England and a European protected species. Studies have shown that the introduction of beavers into rivers can improve water quality, stabilise water flows, store carbon, and establish the types of habitat that are beneficial for many other species. The Wildlife Trusts are now calling for more urgency from the government in providing support to landowners involved in further reintroductions.

Conservation Land Management: Autumn 2022

From a close look at two very different restoration projects in Yorkshire to the eradication of Japanese knotweed without the use of herbicides, the Autumn issue of Conservation Land Management (CLM) covers a variety of topics and themes relevant to those involved in managing land for nature. Below is a summary of the articles featured in this latest issue.

The first of the Yorkshire-based articles, authored by Sarah Lonsdale of the North York Moors National Park Authority (NYMNPA), describes the River Esk Restoration Project. The River Esk flows through the North York Moors and is the only river in Yorkshire to support populations of the rare freshwater pearl mussel. Agricultural pollution and sedimentation threaten the mussel’s habitat and the Esk’s water quality, however, and the Esk Restoration Project aims to address these pressures through habitat creation and restoration, farm infrastructure grants and targeted one-to-one farm advice. Sarah describes how, through this project, the NYMNPA has worked with farmers and landowners to reduce agricultural pollution via riparian habitat creation and improvements in on-farm infrastructure. This has involved, for example, the installation of in-field solar-powered water troughs to reduce riverbank erosion caused by livestock trampling and the creation of wide habitat buffers to help reduce the amount of pollutants reaching the river – Sarah describes these and other approaches in more detail, and discusses the future of the project.

The second article set in Yorkshire is focused on peatlands. Yorkshire’s peatlands contain 27% of England’s blanket bog and support an abundance of wildlife, but changes in land management, for example through drainage and heavy grazing, have led to their degradation. In this article Jenny Sharman describes the impressive work undertaken by the Yorkshire Peatland Partnership to reverse this trend and restore and rewet Yorkshire’s peatlands. Signs of recovery have quickly become apparent, and Jenny guides us through the process of peatland restoration, which begins with initial surveys to assess the extent of the damage using satellite imagery in preparation for work on the ground where a myriad of approaches are used, from using diggers to revegetate exposed peat to installing timber sediment traps and coir logs to help slow the flow of water and retain sediment.

Looking now to a different habitat, Robin Pakeman discusses the management of machair, an extremely rare coastal habitat only found in western Ireland and western and northern Scotland. It develops on shell sand in exposed coastal areas, and refers to the plain behind sand dunes. Human use of machair has a long history, and traditional management combined with specific environmental conditions has produced this wonderfully unique habitat, famous for its spectacular floral displays and bird and insect communities. Crofting, a form of land tenure that only occurs in north and west Scotland, has had a strong influence on Scotland’s machair, and in this article Robin explores the management of both arable and grassland machair, and describes the diversity of wildlife associated with this habitat.

The infamous Japanese knotweed is a problematic non-native invasive species in the UK, and the general consensus regarding its control suggests that the use of glyphosate-based herbicides is required. Aston’s Eyot nature reserve, in east Oxford, was previously a rubbish dump, and since it was badly capped in the late 1940s Japanese knotweed established itself there, suppressing the growth of many other plants that would otherwise thrive. To combat this issue, the Friends of Aston’s Eyot, a group formed in 2010 to care for the nature reserve, decided to trial different approaches to management of knotweed. The trial area was divided into three; two of these were to be treated with glyphosate. In the third area knotweed was to be cut and its emerging shoots would be pulled out by hand. Claire Malone-Lee took responsibility for this third area, and in this article reflects on eleven years of manual control and demonstrates that it is possible, particularly on small sites or where knotweed is not overly dominant, to successfully eradicate Japanese knotweed without the use of herbicides.

When the Able Marine Energy Park project on the Humber Estuary was given the go-ahead, Roger Morris was concerned for the internationally important flock of black-tailed godwits that resided there, and the mudflats that they depended on. The final article in this issue, a viewpoint piece by Roger, asks if it is possible to create sustainable mudflats as a mitigation measure, and explains why it is difficult to stop or slow the process of mudflat becoming saltmarsh. He describes the processes behind saltmarsh and mudflat development, and addresses the different approaches that have and can be used for mudflat creation.

In this and every issue you can expect to see Briefing, keeping you up to date with the latest training courses, events and publications, and On the ground which provides helpful tips or updates on products relevant to land management. Other features, such as Review, which can include letters from readers or updates from our authors, also regularly appear in CLM.

CLM is published four times a year in March, June, September and December, and is available by subscription only, delivered straight to your door. Subscriptions start from £22 per year. If you would like to read any of these articles, back issues are also available to purchase individually (subject to availability).

If you are involved in a conservation project and think your experiences could be useful to other practitioners, we would love to hear from you. Feel free to contact us if you are interested in writing for CLM – we will be happy to discuss your ideas with you.

Author Interview with Susan Young: Wildlife Photography Fieldcraft

This unique book describes a straightforward system for how to successfully locate wildlife, the most difficult aspect of wildlife photography. Photographing the stunning natural world around us can be a challenging process. Not only does getting the perfect shot require a complex mixture of skill and luck, but there is little practical advice available on how to find the wildlife you’d like to photograph. While patience and persistence have to come from you, being equipped with the right fieldcraft knowledge, offered in this book, can increase your chances of getting the results – and the special moments – you are looking for.

Individual chapters offer guidance on how to photograph birds, mammals, butterflies and dragonflies, as well as reptiles and some of our more elusive species. Various habitat types are discussed, along with tips on equipment, technical specifications and guidance suitable to both newcomers and more experienced wildlife photographers. While sharing some of her most successful and beautiful images, Susan Young also gives useful examples of when things didn’t quite work out – reflecting on how things could have been done differently to get a better outcome.

Susan Young speaks with us about why she chose to write this book, her process for researching each chapter and why wildlife photography is so important for engaging the public with the environment and conservation.


Your new book, Wildlife Photography Fieldcraft, is a unique guide to how to successfully locate wildlife. What drew you to wildlife photography and why did you choose to write this book?

I have had a keen interest in nature from an early age. I originally took up (digital) photography for landscapes, but it was a natural progression to wildlife photography so I could keep a record of my finds. When I started with wildlife, I found it very difficult to find suitable subjects, especially the less common ones, and of course many mammals are nocturnal. I studied many books on wildlife photography, but they all seemed to concentrate on photographic techniques and gave little or no information on how to find wildlife. I had written books before on subjects not previously covered, so decided to write the book I wished I had been able to find when I was looking.

You mention in this book that a lack of knowledge on how to find wildlife to photograph may be just as risky as providing too much information, could you expand on this?

This is related to disturbance. If photographers know very little about the subject of their photographs and do not understand the sensitivity of wildlife, they could disturb a bird, for example, and cause it to abandon its nest, or frighten a deer so it runs off and becomes injured.

On the other hand, if too much information is given out, particularly of a detailed location, photographers can flock to the area in large numbers. This has happened with rare birds, for example, and the birds have become very distressed.

Ptarmigan by Susan Young

This guide is broken up into chapters covering different species groups, all of which are richly detailed, covering descriptions, diet, breeding, habitats, population estimates and more. What was your process for researching the different chapters, and why did you choose to go further to cover topics such as how to make a portable hide and thermal and dynamic soaring?

The whole focus of the information was on what factors influenced where, when and how to find wildlife. Population estimates and habitats, for example, influence where the subject might be found in a broad sense. Breeding and its rituals have a great effect on when certain species are most active and thus most likely to be seen. Description, diet and habits are more detailed indicators allowing the photographer to fine-tune the search, for example. Goldfinches like thistle seed (diet), they are often in flocks (habits) and have distinctive colouring (description), so a photographer situated near a patch of large thistles, at the right time of year, could have interesting photographs of goldfinches balancing on thistles and interacting with each other.

My process was to think of each category for different species and, based on my experience, record the facts for each species and describe how to use them to find wildlife. I then studied reliable sources to add further detail and confirm that what I already had was accurate.

Hides are extremely valuable as they allow the photographer to get close to nervous or rare species without disturbance. Portable hides are particularly useful. I found it difficult to get a flexible, sturdy, inexpensive portable hide that would be comfortable if sat in for some time. My design was based on the plastic pipes I had seen on an American trip, and can be tailored to the individual very easily, and is strong but not too heavy.

Photographing birds in flight, especially birds of prey, is very difficult. By understanding thermal and dynamic soaring, the photographer is equipped to predict the best position to photograph a bird in flight i.e. when the bird is moving more slowly and at the correct height.

How important do you think wildlife photography is in increasing public engagement with the environment and conservation?

Wildlife photography is hugely important as photographs can convey an emotion or fact better than words, and in particular can illustrate features or situations in a compelling, thought-provoking way, or simply attract by their beauty.

Sand Martin and chicks by Susan Young

Your case studies provide a wonderful insight into your photography process. Are there any species that you haven’t yet photographed but would love to?

Pine Martens are at the top of the list. They are beautiful and intelligent but, at present, rare in England. Beavers are another species I would like to photograph, and hopefully, this will become easier if they are introduced to other parts of the UK.

Do you have any current or future projects that you would like to tell us about?

At present I am developing interactive online mini-courses for the Mammal Society using photographs, videos and interactive features. The aim is to attract and engage with more people to gain their support in the quest to learn more, and use the knowledge to try to halt the decline of UK wildlife. I am also developing a course to encourage the use of CCTV systems to monitor wildlife.

Climate change

A new report shows that Australia is funding just one-tenth of its fair share of global climate action. The study by Oxfam and ActionAid Australia is calling on Australia to increase its climate finance commitments to $3bn, ahead of COP27 this November. Currently, Australia has only committed $400m a year between 2020 and 2025 for international climate funding. For Australia to meet its fair share of the dedicated $100bn fund agreed upon in 2009, its contributions must be $4bn annually from 2025.

Both wild and farmed Atlantic salmon are threatened by warming waters. The climate crisis is warming the world’s rivers and oceans. As warmer water contains less oxygen and simultaneously speeds up the salmon’s metabolism, increasing the need for oxygen, warmer temperatures are reducing salmon fitness, impacting their abilities to adapt to stressors. Studies by the North Atlantic Salmon Conservation Organization have shown that, from 2007 to 2016, only a single salmon survived its first year from 2,000 fertilised eggs, whereas prior to 1990, it would only require 1,000 fertilised eggs.

The UN has warned that the world is ‘heading in the wrong direction’ as the impacts of climate change worsen. The 2022 United in Science report has shown that there are five times as many weather, climate and water-related disasters as there were 50 years ago. The last seven years (2015-2021) have also been the warmest on record, with a 93% chance that at least one of the next five years could be hotter than 2016, the warmest year on record. To meet the 1.5°C goal set out in the Paris Agreement, current emissions reductions need to be seven times higher than they are now.

Research

A study has created a new framework to change how sharks, rays and chimaera species are considered in the design of protected areas. This will hopefully help provide the protection they need in the face of extinction. Sharks are apex predators and play a vital role in the functioning of balanced ecosystems, shaping communities and ensuring biodiversity. They’re threatened by fishing practices, either as targets or as by-catch, as well as negative public images which can lead to culls. By ensuring that the most up-to-date information is provided to governing bodies, policies and protected areas can be designed to ensure the protection of these species.

Satellites are now able to measure the thickness of sea ice in the Arctic Ocean all year round. Previously, spacecraft struggled to measure the state of sea ice in summer as the presence of surface meltwater confused instruments. Now, using ‘deep learning’ techniques, scientists are able to get reliable observations across all seasons. This will help to improve monitoring the impacts of climate change, while also aiding weather forecasting.

Researchers have found the world’s oldest heart preserved inside a fossilised prehistoric fish.  The 380 million-year-old heart was made in Western Australia and captures a key moment in the development of the heart found in all back-boned animals. Soft tissues are far less likely to be preserved than bones but the minerals of the Gogo rock formation preserved many of the fish’s internal organs, including its liver and stomach.

Conservation

A fungal outbreak is threatening the tricoloured bat with extinction in the US. White-nose syndrome, which disrupts the crucial winter hibernation of bats, is ravaging tricolour bat populations, as well as populations of a dozen other North American species, including the northern long-eared bat. Both of these species have been recommended for endangered designation by  The US Fish and Wildlife Service.

Two adult grey wolves, along with two cubs, have been spotted in Oregon’s Cascade mountains, giving hope that the federal protections restored earlier this year are aiding the recovery of this endangered species. After decades of hunting across the US, Oregon recorded only 14 individual wolves at the end of 2009. Since then, following protections from the Endangered Species Act, the population has grown to 175 individuals in 2021.

Cheetahs have been released in India for the first time, 70 years after they went extinct. Eight cheetahs were flown into the northern Indian city of Gwalior from Namibia. They have been released into a fenced enclosure in Kuna National Park for their quarantine period over the next month, before being released into a larger enclosure containing natural prey. Their release into the wild is controversial, particularly as a population boom of another of India’s predators, the tiger, has led to increased conflict with people sharing the same areas.

Pollution

A Coalmine wastewater spill has turned a creek in Royal national park, Sydney, to black sludge. This is the third coal pollution incident involving Peabody Energy’s Metropolitan mine this year. The Environment Protection Agency of New South Wales have collected water samples and are conducting further assessments to determine the ecological impacts of this event. There is concern that this pollution may impact the state government’s plans to reintroduce platypuses to the area.

Great British Beach Clean 2022

What is the Great British Beach Clean?

The Great British Beach Clean is organised by the Marine Conservation Society (MSC) and takes place in September every year. During this nine day period, thousands of volunteers gather together on beaches around the UK to collect the litter they find on and above the strandline. This huge event has taken place since 1994 and occurs alongside the International Coastal Cleanup.

This year’s Great British Beach Clean runs from Friday 16th to Sunday 25th September.

What does a beach clean involve?

A beach clean has two purposes: firstly to remove potentially harmful and unsightly waste from our coastline, and secondly to gather data on the types of litter that are polluting our beaches.

During a clean, volunteers are asked to collect and record all of the litter they find on and above the strandline over a 100m stretch of beach. This information is then sent to the Marine Conservation Society, who collate and store it in a database. While collecting, volunteers also look out for other items such as tangled animals, patches of oil, or items that have originated from abroad, as these can be also be recorded.

At the end of the beach clean, bagged up rubbish is weighed and then deposited at a local collection point (with any hard, recyclable plastic kept in separate bags if possible).

Volunteers aren’t restricted to cleaning only 100m of the beach of course, but recording over a specific length of coastline makes the submitted data easier to compare.

What happens to the collected data?

The data collected during the Great British Beach Clean is as important as the clean-up itself as, without knowing what items are commonly found on our beaches, it is difficult to know where the most serious problems lie. With almost 30 years’ worth of data to hand, the MSC can now look at trends and patterns over time and make important decisions about where to focus their attentions.

The information submitted each year by volunteers is compiled and stored by the MSC who use it to campaign for better legislation relating to plastic waste, and to direct public awareness campaigns to help change consumer behaviour. To date, the MSC has been instrumental in bringing about the 5p plastic bag charge, which has seen the number of plastic bags washing up on beaches decrease by a huge 61% since 2011. They have also lobbied for wet wipes to be more clearly labelled, as they are not only responsible for massive blockages in sewerage systems, but many also contain plastics which break down into harmful microplastics in the aquatic environment.

They are currently working towards bringing in a Deposit Return System for drinks bottles and cans. The 2021 British Clean found an average of 30 drinks-related items per 100m. By making consumers pay a small deposit at the time of purchase, which is returned to them when they bring their bottle or can back for recycling, it is hoped that the number of such items ending up in the aquatic environment could be significantly reduced. A Deposit Return Scheme is due to be unrolled in Scotland in August 2023, but so far England, Wales and Northern Ireland have yet to make similar plans.

Other campaigns include the ‘Don’t Let Go’ movement, which aims to ban balloon and sky lantern releases, as debris from these items provides a significant source of pollution.

How do I get involved:

To find an organised beach clean near you, simply head over to the MSC website and search their events database. If you can’t find one, then you can always organise your own. All you need to do is register as a volunteer and then the MSC will provide you with all the information you need to get started.

If you don’t live near the coast or aren’t able to attend a beach clean, you can still help by making a one-off donation to the MSC or becoming a member.

Recommended books and equipment:

The Essential Guide to Beachcombing and the Strandline

In this handy guide you will find an in-depth account of the animals and plants that make up this rich and continuously shifting oasis of life in the otherwise harsh and hostile environment of the beach. The more we come to terms with the sensitive nature of the strandline, the more we can do to nurture and protect it.

 

The Beachcomber’s Guide to Marine Debris

This richly illustrated book serves as the ideal guide to the items that litter the world’s beaches. Forget sea shells and other fauna and flora. Here, you will find what a beachcomber is actually most likely to encounter most these days: glass, plastic, wood, metal, paper, oil and other sources of marine pollution.

 

FSC Wildlife Pack: Seashores

The Seashores wildlife pack is a presentation pack featuring 5 different fold-out guides – explore the wildlife of our coastline, from birds to seashells. The pack also includes a card-sized magnifier to help you get in ever closer to the details. Includes guides to cetaceans and seals, rocky shores, seashells, seaside flowers and summer coastal birds.

 

Litter Picker

This 82cm litter picker is constructed from lightweight, robust aluminium with an easy grip handle for comfortable use. With a grooved jaw for extra grip and a rotating head for increased flexibilty of use, it’s an ideal tool for any bioblitz, beach clean, or similar environmental event.

Equipment in Focus: Spring Frame Butterfly Net

The Spring Frame Butterfly Net is a compact net for anyone interested in studying butterflies or moths. Designed and built by NHBS in our Devon workshop, the net comprises of a short-handled frame, net and cover.

Bag, Net, Spring Frame and Instructions

Because of its lightweight metal frame, it can be folded down to fit into the supplied travel bag, neatly allowing it to be stowed away in a rucksack while out in the field. The main net is olive green and opens to a diameter of 30 cm. The short handle makes it easy to use at close quarters while trying to sample butterflies. 

When you receive your net, you will find it collapsed down inside its carry bag along with instructions for folding it back into the bag after use. To help you do this, I’ve gone through the process of collapsing the net in the steps below.

Steps to collapse your net

Start with a hand holding the open net with the bag draped below – held in the right hand.

Grip the top of the frame with your thumb ready to push from the underside of the frame.

Keep your right thumb over the screw that attached the frame to the handle.

Use your left hand to twist the frame into a figure eight. Your left thumb should help because it will be pushing from underneath the frame.

Twist almost completely with your left hand over the top of your right hand with your index finger ready to clasp the folded rim. The frame should naturally want to fold over itself.

With the frame folded, use your left hand to wrap the net around the folded frame to keep it from springing open. The net can now be safely stored in the bag provided.

Other equipment

It is also worth considering stocking up on a few supplies if this is the first butterfly net you have bought. 

A spare net: While the net is hardwearing, it is always worth considering keeping a spare net on hand. You can purchase additional nets on the NHBS website. 

 

 

A hand lens: Ideal for examining any butterflies that you have sampled. NHBS carries a selection of hand magnifiers that you can keep in your pocket. This particular lens is a 15 x magnification which is extremely good for viewing the beauty and detail of the butterfly.

Collecting pots: NHBS carries a selection of different types of pots that can be used for transferring a butterfly from the net to something you can view the butterfly with.

In the event that you wish to extend the handle, additional lengths and styles are available. For example, you can extend the handle to either 50 cm or 90 cm with the fixed length long handles such as the Professional Butterfly Net: Handle, or for a more flexible approach you can choose the Telescopic Handle that extends the range of the net between 82 cm and 125 cm reach.


The Spring Frame Butterfly Net can be found here. Our full range of butterfly nets can be found here.

Phenology Series: Autumn

Autumn is a time of great change for the natural world. Hedgerows are bursting with nuts and berries, the landscape is shedding its green lushness in favour of reds and golds, and animals large and small are beginning their preparations for winter – whether that be by storing food, getting ready to hibernate, or migrating south where the weather is warmer and food more plentiful.

Although the days are shorter and the weather cooler (and almost certainly wetter!) autumn is a wonderful time for observing nature. As our focus shifts from the butterflies and flowers of summer to the fungi and garden bird feeder, this season also brings us some of nature’s most incredible spectacles.

This is the third in our seasonal phenology series where you can explore a carefully chosen collection of ID blogs, books, equipment and events, all designed to help you make the most of an autumn outside. Check out our spring and summer blogs and don’t forget to look out for our winter blog in December.

What you might see:

• During the autumn, most of our summer migrants will begin to head off for warmer climes. Swallows and House Martins will depart on their lengthy migration to Africa, where they will spend the winter before returning to us next spring. At the same time we see the arrival of other species such as Fieldfare, Redwing and several species of ducks and geese. Many will spend the winter in Britain whilst others will stop off briefly to feed on their way elsewhere. Some coastal species, such as Puffins and Gannets leave during the autumn to spend the winter at sea.

• Peaking in late November and early December, Starling murmurations are one of the most spectacular events in the wildlife watcher’s year. These magnificent clouds of birds, swirling and turning in perfect unison, can be made up of more than 100,000 individuals. The best time to see murmurations is in the early evening – this is when the birds take to the skies to find their night-time roosting spots.
•As days shorten and temperatures cool, the natural pigments in tree leaves change, and we are treated to a final burst of colour before the leaves fall and winter sets in. Parks and deciduous woodlands are the perfect place to witness this wonderful palette of red, gold and copper throughout the autumn.

• October is the ideal time to observe the deer rut. Our three largest species of deer (red, fallow and sika) all perform this spectacular behaviour which involves rival stags roaring and locking antlers in battle in order to gain access to females, who are only fertile for around one day each year. Exmoor, Dartmoor and the New Forest are particularly good locations for observing these iconic displays.
• With the cooler weather and increased rainfall, autumn is usually the best time of year for spotting fungi. Following a spell of rain, grassland and woodland can suddenly be carpeted with an array of fascinating species. Giant puffballs and the stunning fly agaric are two easily identifiable and impressive species to spot.

• During the autumn, salmon will migrate from the open ocean back to their home rivers in an effort to reach the higher reaches of clean water where they will breed. As they travel upstream they can jump up to three metres upon encountering waterfalls or other obstacles. Although risky for the fish, as jumping out of the water makes them vulnerable to predation, these spots provide an excellent chance for us to observe the salmon run in action.

Book Review: Goshawk Summer: The Diary of an Extraordinary Season in the Forest

Winner of the James Cropper Wainwright Prize for Nature Writing 2022. 

Chronicled in Goshawk Summer: The Diary of an Extraordinary Season in the Forest, wildlife cameraman James Aldred is given the once-in-a-lifetime opportunity to film a goshawk nest during the first few months of the pandemic. Having just completed a migration himself, returning home after filming a cheetah family in Kenya, he was commissioned to begin filming in the New Forest. However, after the adventures of finding a suitable nest and planning how to set up the shoot, lockdown began. The everyday hustle and bustle of everyone going about their daily lives stopped. In the spring months of 2020, with everyone staying at home, no cars on the road, the absence of aeroplane vapour trails crisscrossing the sky, an eerie quiet descended. And perhaps most importantly, lockdown meant no more visitors to the New Forest – except for James.

After harpy eagle attacks, being chased by venomous snakes, and almost being knocked out of a tree by an elephant, you’d think Aldred wouldn’t have much excitement for our native wildlife. However, the awe that Aldred has for not just goshawks but for many of our species shines through in this book. For all its named ‘Goshawk Summer’, this book reads like an ode to the threatened aspects of Wild Britain. It is a whistle-stop tour of our countryside, from instructions on the management of heathland and the place muntjac have in our ecosystems, to the plight of the Dartmoor warbler, pine martens, and the curlew, and even the cultural relationship we have with foxes.

The wealth of experience he has gained over 25 years of working in the industry is clear throughout this book. Passages are filled with rich tidbits of wildlife encounters, such as the time he found all six native reptile species in one morning. Each sighting and mention of a species is accompanied by a short tale or a piece of history. Often, these sightings are compared to Alred’s experiences with more exotic ones, such as the pine marten with the yellow-throated marten in Borneo, a group of tumbling fox cubs with the cheetah family in Kenya, and the goshawk as “our very own mini-harpy”. It is a welcome reminder that UK wildlife can be just as magical and mysterious as that of far-flung places.

Goshawk by Andy Morffew via Flickr

Written from field notes kept at the time, the internationally experienced wildlife cameraman dives into the wildlife of his childhood haven of the New Forest. He describes the lack of human activity and disturbance as a glimpse into paradise, which, through his engaging observations, we too can experience. The goshawks are the true highlight of this book, as Aldred gives us a window into the seemingly timeless forest away from the jumble and stress of modern life. Following the weeks and months of Aldred’s shoot, we see the day-to-day workings of a goshawk nest and the trials and tribulations of a species once hunted to extinction. While watching the development from eggs to fully fledged juveniles, Aldred tells the history of this previously highly persecuted species.

As lockdown eased and travel was allowed, the spell is broken and it seems that suddenly everyone is using natural spaces. Car parks and roads fill and forest paths become alive with walkers, music and cyclers. Unfortunately, while many reported this as the public’s increasing appreciation for our natural landscapes, Aldred has a different opinion. With the pandemic always running in the background, he documents the impacts of the sudden rush to reenter the world. From the increase in noise, litter, risky barbeques, irresponsible drivers and dog owners, the newfound peace of the New Forest seems shattered. The forest is described as a habitat that “has been abused for centuries” and Aldred reaffirms the emerging narrative that we should step back to give nature space to breathe and recover. Throughout Goshawk Summer, Aldred issues a strong call for people to be more conscious and considerate of their behaviour in nature, particularly around nesting bird season.

Returning in February 2021, almost eight months after watching the goshawk chicks fledge, Aldred once again encounters the goshawk female. He notes a feeling of elsewhereness within the forest, of outside being England and inside “somewhere much further north”. Goshawk Summer mirrors this, providing a fascinating glimpse into the perspective of a wildlife cameraman and a welcome break from the clutter of the outside world. This book was awarded the James Cropper Wainwright Prize for Nature Writing 2022.
