Author Q&A: Peter Fretwell and Lisa Fretwell – The Penguin book of Penguins

A Fellow of the Royal Geographic Society, Dr. Peter Fretwell, like the subjects of his new book entitled The Penguin book of Penguins, spends the majority of his time in the cold. As a senior geographic and remote sensing scientist, Peter has been responsible for leading many projects that further our understanding of the Polar regions and the wildlife that inhabits the area. Establishing and contributing to key projects to help better understand predators in the polar region by using satellite imagery has assisted in crucial conservation efforts.

For this book, Peter has joined forces with his wife Lisa who provides a unique selection of illustrations throughout the book. As an artist of over 30 years, Lisa draws on a wealth of experience having exhibited her works in London and New York.

We were lucky enough to catch up with Peter and Lisa recently to talk about the new publication.

What inspired you to write “The Penguin Book of Penguins”? Why penguins?

Peter: Strangely, there has never been a book titled The Penguin Book of Penguins, so when we were asked to write it, it was an opportunity we couldn’t turn down. I had previously written the Antarctic Atlas, published by Penguin Random House in 2020 and I have worked with penguins and on penguin science for twenty years. These small charismatic creatures are such a delight to be involved with, and they are a major part of working in Antarctica. Working at the British Antarctic Survey you pick up stories and anecdotes about them almost by osmosis, so having a chance to relay those narratives to a wider audience is a real privilege. We all love the jovial nature of these unique birds and their amazing adaptations to survive and thrive in some of the most challenging environments on Earth, but there is a more serious message that I also wanted to convey about the challenges that many of the species now face with climate change, pollution, habitat loss and overfishing. Communicating these challenges to a wider audience is one of our main drivers, whilst keeping the message light and not too “preachy”, to engage and inspire that wider readership. What was more, we decided we wanted to include drawings rather than photos, so my wife, Lisa, who is a professional artist joined the author team to bring the illustrations to life.

How has your work as a cartographer and scientist at the British Antarctic Survey influenced your writing and perspective on penguins?

Peter: I really started researching penguins through my work on mapping and remote sensing. I started my scientific career as a geographer and got a job in the British Antarctic Survey as a cartographer. I have always loved maps, especially mapping the natural world around us, but I also loved the science and was soon not just making maps but helping with the geospatial analysis. The British Antarctic Survey is a wonderful and diverse place for environmental science and to help the scientist analyse their data was fascinating – you never knew what you might be working on; one day it could be mapping and analysing volcanoes, and the next it might be cuttlefish distribution. In 2008, whilst making a map for our pilots, I discovered that we could see emperor penguin colonies in freely available Landsat satellite imagery. At the time, we didn’t know how many emperor penguin colonies there were or their distribution, so it was a groundbreaking discovery.

How has the use of satellite imagery revolutionised the study and conservation of penguin colonies?

Peter: Fast-forward 17 years and we now know that there over double the number of colonies that we thought there were. We track their locations each year and do annual population assessments using satellite imagery. We have also used the technology to discover unique, previously unknown behaviours and traits, and we have witnessed and recorded the struggles and calamities they suffer as the continent warms and the sea ice diminishes. The Earth observation methods that we developed for emperors have been transferred to many other species of penguins and other types of wildlife around the world. My job itself has changed dramatically, from a scientific cartographer to a remote sensing expert and an expert on penguins and other polar vertebrate species that we track from space.

What were the major obstacles or challenges you’ve come across during your study of penguins?

Peter: Using satellites is a brilliant way to study these animals as most of the colonies are in extremely remote locations, where on-the-ground research is almost impossible. Even now the resolution of the most powerful satellites is still not good enough to see every individual adult and chick. We still need to get out there to calibrate our satellite counts and see how accurate they really are, but getting to emperor penguin colonies and synchronising ground (usually a unmanned aerial vehicle or UAV) counts with satellite data is really challenging, not just for emperor penguins, but for all the wildlife that we study from space. One of our current technical challenges is to improve the methods.

Lisa: Finding the inspiration and imagery for the more temperate penguins was quite challenging. The Antarctic and sub-Antarctic penguins were easier, as Peter had taken hundreds of photos of all the species throughout his career that I could work from. We had also visited New Zealand and seen many of the penguin species, like the adorable little blue penguin, there. On his travels, Peter had also photographed penguins on the Falklands and South America, but there were still some species that we had to trawl through published sources to get good reference images for. You have to be careful as what you see on the internet is not always correct, but it helps when you are married to a penguin expert!

Many people feel rather enamoured by penguins. Why do you think that is?

Peter: I agree, and it’s hard to put your finger on the reason. Maybe it is a combination of their comic trusting nature and the fact that they are one of the few animals that stand upright on two legs, which makes them look a bit like us. It is really hard not to anthropomorphize penguins and compare them to little people with similar habits and social structures. Like us they often live in huge congregations, sometimes hundreds of thousands strong, they have complex courtship routines, bicker with their neighbours and do daily commutes to look after the family. They are also very tame, curious and often clumsy, which makes them quite endearing. Add their incredible, unique abilities in response to their challenging environments and you have an animal that really is quite engaging.

What are the biggest misconceptions about penguins that you would like to clarify?

Peter: There are many. Firstly, and perhaps obviously, penguins are a bird. They have feathers, not fur. Secondly, not all penguins live in Antarctica. A minority, only four of the eighteen species, breed around the coasts of the Southern Continent, but it’s fair to say that almost all (except for a few hundred) live in the Southern Hemisphere and most of them would call the waters around the Southern Ocean home.

What are the primary threats to penguin habitats, and how can these be mitigated?

Peter: It’s not just their habitats, but we can start there. Over the years, penguins have been eaten, killed for their feathers, had their eggs collected in their millions, been squashed and boiled down for their oil, and had their nesting habitats dug up and destroyed for fertiliser. In more recent times, urbanisation and land clearance has affected some of the more temperate birds, and the introduction of non-native species has had a devastating impact on many of the island-living species that are endemic to just one small group of islands.

Today, the main threats to the temperate species of penguins that live close to humanity are pollution from oil spills, overfishing and bycatch in their foraging grounds. But even in Antarctica and the remote island homes of penguins that no one ever visits, the influence of humans is affecting populations. Climate change is a global, man-made phenomenon that cannot be averted at a regional scale and is starting to have dramatic effect on many species. Although it is fair to say that in a warming environment, there will be winners and losers, at the moment, it looks like we will see more losers than winners.

What conservation efforts have been most effective in protecting penguin populations?

Peter: Around the world there are many amazing people and organisations helping penguins, from re-homing little penguins in New Zealand and Australia to the fantastic efforts to save African penguins from oil spills. In South America, there has been a great effort to protect breeding colonies from predation and on many sub-Antarctic islands there have been great programmes to eradicate non-native species that eat eggs and chicks, and trample breeding sites. There are fantastic efforts in many places that are saving penguins from the brink of extinction that anyone who loves or admires these birds should be grateful for.

Personally, what thoughts and feelings were you left with after this study of penguins?

Peter: Writing the book has not only highlighted how much we love penguins and how our culture has embraced these charismatic birds, but also the paradox of how badly we have treated them over the years and how threatened they are from human activity. Today most of those threats are indirect, but they are still caused by us and can still be solved by us.

Lisa: In terms of illustrations, I had to re-draw the ‘Penguin Digestor’ numerous times, because it made me feel a bit queasy just thinking about it. If you look at the original image it is very expressive and full of angst! I left those images of how we had mistreated penguins, like the Digestor and the Egg Collector until the very end when I could summon up the will to re-engage with them.

How do you envision the future for penguins?

Peter: For many species, it is a worrying time. Several are on the brink of extinction; some, like the emperor and chinstrap, are on a worrying trajectory caused by climate change that can only be solved at a global level. But there is hope. So far, we have not made any species of penguin extinct and there is still time to save all of the wonderful types of these birds, but the window for doing that is growing narrower every year.

What are the most important impressions you would like the reader to be left with after reading “The Penguin Book of Penguins”?

Peter: We hope readers will come to understand how wonderful and loveable these birds are and how invested into our culture they have become. When we think about the future of penguins, it can be a little depressing, but we are not there yet and that future is not yet written. If people care about a subject, then maybe they have it within their power to alter the future so that the worst predictions never come to light. If this book does anything, we hope it will enthuse people to help save penguins.

Lisa: I also hope that my illustrations enhance and portray these amazing birds in a true light. I tried to capture their personalities, particularly their behaviour, which I think is absolutely fascinating! The infographics should enable the reader to differentiate between each species, which for some penguin families, especially the banded penguins, is very subtle. I wanted to portray how endearing and intelligent these birds are. They have evolved to survive against the odds and their quirky nature is often fundamental to whether they breed successfully, survive extreme weather conditions and ultimately sustain their populations, and I wanted to reveal these quirks visually to enhance the reader’s experience.

What future research or projects are you planning on currently?

Lisa: I am planning to enhance my penguin illustrations with colour and exhibit them at a number of galleries. I have already been asked to create some other wildlife illustrations for the Arts Society Youth Fund locally, and I hope to illustrate or even write more books in the future.

Peter: I am currently leading multiple projects on penguins and other polar wildlife. My penguin-themed projects include mapping and monitoring seabirds on South Georgia, recording and improving the methods, carrying out population surveys of emperor penguins, and counting chinstrap and Macaroni penguins on the remote South Sandwich Islands. Results from all these studies should be coming out over the next year.

The Penguin Book of Penguins is available as a limited edition signed hardback book, while stocks last, from NHBS here.

Author interview with Trevor Dines on Urban Plants

The 15^th volume in the insightful British Wildlife Collection is this timely and illuminating journey into the wild lives of Urban Plants. In this book, Trevor Dines explores the floral species that pioneer our pavements and walls, break ground in our towns and cities and strive to connect corridors for pollinating invertebrates through our built-up landscapes. Trevor also looks to the future and the potential impacts of invasive species, herbicides and climate change, as well as the concept of urban rewilding.

Trevor Dines, a farmer’s son from Hampshire, co-authored the New Atlas of the British and Irish Flora, mapping every native and naturalised plant in these islands. A campaigner for better management of road verges and lawns and the creation of wildflower meadows, he appears regularly on the Radio 4 Today programme, BBC Breakfast and Countryfile. Trevor also presented Channel 4’s Wild Things and wrote the accompanying book The Wild Things: Guide to the Changing Plant Life of the British Isles.

We recently had the pleasure of asking Trevor more about why and how he came to write Urban Plants

Firstly, can you tell us a little about yourself and how you came to write the 15th volume in the renowned British Wildlife Collection?

I was incredibly lucky to grow up on two farms -one in Wiltshire and another in Hampshire -where I developed a deep passion for wild plants. I’d spend hours searching dad’s fields for rare arable flowers like Venus’s-looking-glass and Rough Poppy, as well as orchids on the chalk downland. After leaving Bangor University with a PhD in plant architecture, I worked for the Botanical Society of Britain and Ireland, co-authoring the New Atlas of the British and Irish Flora (2002). This is when I really got to know our flora, travelling the length and breadth of the country meeting plants and the network of incredibly talented plant recorders that are so happy to share their knowledge. For 20 years I then worked for Plantlife – the plant conservation charity – in particular championing the creation of wildflower meadows, the better management of road verges, and changing attitudes towards lawns through the invention of No Mow May.

During this time, I also presented a Channel 4 TV series (Wild Things) that showed how and why plants are changing their distributions around Britain and Ireland. This led to more work in the communications side of things at Plantlife, something I’ve always had a passion for because it’s such an important element of conservation. This was an exciting time, with appearances on BBC Countryfile, BBC Breakfast and Gardeners’ World, as well as many local radio and newspaper interviews and writing articles for magazines. Katy Roper, Commissioning Editor at Bloomsbury Wildlife, became aware of my work through an item I’d written about the spread of Oxford Ragwort and invited me to consider writing a book on urban plants for the series. I was, of course, thrilled at the prospect, and threw myself into the project in 2022 when I became a freelance botanist.

Flowers in a Conwy street by Trevor Dines

My favourite excerpt from the book was hearing about the newly established population of Lesser Tongue-orchids thriving on the roof of a large city bank. Do you have a favourite, but possibly less well-known, urban botanical enclave you can share with us?

I particularly enjoy finding mundane or even rather grotty places with completely unexpected plants. Between a footbridge and the railway into my local town, Conwy, for example, there’s a thin sliver of fallow waste ground that’s home to a very bizarre mix of plants. Alongside the usual suspects like Buddleja and Oxford Ragwort, bright pink Pyramidal Orchid and Zigzag Clover push up between clumps of Pampas Grass, an increasingly invasive garden escape from South America. And, for the last few years, Iris reticulata × histrioides ‘George’ has also flowered here, the only place in Britain where it’s known to be established outside gardens. Tantalisingly, all these plants are unreachable behind a metal fence, adding another level of challenge for the urban botanist.

There has been a sad decline in the number of higher education courses offering botany as an option. However, with the news of the natural history GCSE coming this year, how would you integrate uUrban botany into the course as a way to encourage future botanists?

Urban botany is unique in being accessible to everyone, everywhere. You don’t need to travel to a nature reserve, a woodland, a meadow or other special place to engage with it – it’s quite literally right there on your doorstep. This makes it an ideal subject for the new GCSE, and there are lots of opportunities. Students could look at the phenology of flowering through the year, counting the number of flowers in a given area from the first Dandelions and Groundsel of the year to Herb-Robert and Red Dead-nettle at Easter, and finally Red Valerian and Purple Toadflax before the end of term. Or they could study local walls, seeing how the vegetation varies according to building materials and the direction the wall faces. Or they could look at the impact of footfall on pavements, with fewer plants in areas having most pedestrian traffic. The important thing is that urban plants are fascinating because every species has a story to tell; I love the reaction from kids when you tell them that germinating seeds of Shepherd’s-purse actually kill nematodes to help them survive. It helps bring their environment alive (unless you’re a nematode!).

Rewilding is a hot topic in conservation and biodiversity, and No Mow May is a growing campaign many partake in. Can we ‘rewild’ our immediate environment with this changing mindset to benefit urban plants and biodiversity?

I’m glad you’ve put ‘rewild’ in quotes, as it’s become such a diluted phrase – it now seems to cover any conservation action, from planting wildflowers in a window box to reintroducing beavers. Rewilding in its original form (the reintroduction of charismatic mammals to kick-start natural processes) is very difficult to do in urban areas because habitats are so fragmented and anthropogenic pressures are so high. As engaging as they are, I’m afraid beavers can’t do much to improve the diversity of life in the built environment.

But for many people, rewilding simply means reining back on the intensity of management (or even abandoning management at all) and just letting things grow, seed and recover. And in this case, yes, it’s what the urban environment desperately needs. As the creator of the No Mow May campaign, it’s fantastic to see how this approach has captured people’s imaginations and encouraged us to put the mower away, hopefully not just for May but the whole of summer. The results can be spectacular, with orchids appearing on lawns and mini-meadows with carpets of White Clover, Selfheal, Bird’s-foot-trefoil and buttercups.

Urban biodiversity is all about the tension between our desire for control – an environment kept ‘neat and tidy’ through the use of herbicides, mowing and strimming – and our desire for something wilder. We are, I think, still exploring this relationship, trying to become more comfortable with ‘messier’ streets. Many towns and cities are relaxing their use of herbicides and allowing more vegetation to grow, but then often face a backlash from the neat-and-tidy brigade. Hopefully, as is the case in much of Europe, we’ll become more relaxed in the future and begin to embrace more flowers on our streets in the future.

You discuss how the successional stages of our urban landscape provide a unique opportunity for plants from around the world, which is a win for cosmopolitan biodiversity. What can we learn as individuals from the resilience of this vast array of plant life?

I think botanists inherently appreciate that diversity is not just a good thing, but the very foundation of resilience. Each species has its own suite of unique characteristics that help it survive – be it tolerance of drought or pollution, the ability to set seed within just a few weeks, or a particularly successful method of dispersal – and building communities of plants with these different traits helps them survive the intense stresses of the urban environment. We humans are just the same; we are all different, we all have different skills and talents, and we all bring something unique to the party. And if we come together and draw strength from our diversity, we’re much more likely to cope with the everyday stresses of urban life.

Finally, what’s taking up your time at the moment? Are there any other projects you’re working on that we can hear about?

I’m currently working for the Species Recovery Trust, a small but brilliant charity that’s dedicated to the long-term survival and recovery of a suite of highly threatened species. Alongside traditional conservation subjects like Field Gentian and Forked Spleenwort, I’ve just started working on Welsh Groundsel (Senecio cambrensis) – a hybrid between Oxford Ragwort and Common Groundsel. This unique endemic species is only found in north Wales where it grows along pavement edges, roadside hedgerows and on waste ground, usually in urban settings. Unfortunately, it’s fallen victim to the neat-and-tidy brigade, having been lost from dozens of sites due to herbicides and strimming. It’s now only known from five places and is on the brink of extinction, so we have a lot of work to do to bring it back. But I relish this sort of challenge and hopefully we can recover some lost populations in the next few years.
