Reintroducing the griffon vulture in Bulgaria: an interview with Emilian Stoynov

Emilian Stoynov, vulture conservationistEmilian Stoynov and colleagues created the Fund for Wild Flora and Fauna (FWFF) in Bulgaria in 2000 to support a project to reintroduce griffon vultures in the country.

Emilian has been involved with vultures for many years and in 2007 won the Whitley Award for work with reducing the threat to wolves, bears and vultures from humans and poison in Bulgaria.

A book summarising the griffon vulture reintroduction process from 2010 to 2015 has just been published.

How did you become interested in working with vultures, and how did you come to be a part of this reintroduction project?

When I was a child I was interested to explore nature. At that time there was not much literature to find and to learn about nature. First I wanted to work on plants. Just around 1985 the first edition of the Red Data Book of Bulgaria was published and I tried to buy a copy and start studying the species. But when I had enough money from my parents and relatives around New Year’s Eve, I did not succeed to find the Volume I of the book- plants. I found after checking a lot of book stores in Sofia the Volume II- animals. It was only one copy of the book and part of it was missing (reptiles and amphibians), but the birds were there. I found that some of the rarest birds were the vultures and they were historically found in the area of my father’s birth town – Kotel. Here I started to wish to meet vultures in nature. After some time I became a member of Bulgaria Society for the Protection of Birds (BSPB) – now BirdLife Bulgaria – which was just established and was in charge of the conservation of last colony of griffon vultures in the country in the Eastern Rhodope Mountains. I was first a volunteer and later was working for the project for conservation of vultures in this area. Then I started to think about restoring the population in other sites in Bulgaria. I tried to organize feeding sites in other parts of the country where vultures historically were present, but this was not enough to restore the old colonies. Then I saw what was done in Massif Central in France by Michel Terrasse and his colleagues from FIR/LPO– namely reintroduction of griffon vulture through release of captive bred but also rehabilitated birds from Spain. Thus I decided that this should be done also in other parts of Bulgaria. BSPB were not very willing to work on reintroductions, which is why it was necessary to create a new NGO to work on reintroductions – Fund for Wild Flora and Fauna (FWFF) – created in 2000.  Then I married Nadya Vangelova- and we went to live in her town – Blagoevgrad. The nearest historical place for vultures was Kresna Gorge (only 25 km away from the town) and it appeared it was still suitable for vultures, but they were gone extinct in the 1960s due to a mass and well organized state level poisoning campaign targeting terrestrial predators. Ten years later after the establishment of FWFF we succeed to implement the reintroduction of the species in Kresna Gorge, which is now presented in the current book.

Tell us about the Kresna Gorge in terms of biodiversity – what sort of place is it, and how do vultures fit into the ecosystem?

Reintroduction of Griffon Vulture Gyps fulvus in Kresna Gorge, Southwest Bulgaria 2010-2015

The Kresna Gorge is one of the very few places in Bulgaria with Mediterranean climate. This, in combination with steep slopes and rocky outcrops, makes the area very interesting for biodiversity. Some species of Bulgaria’s reptiles are found only here. Autochthonous loose forests of Juniperus excelsa were declared nature reserve and many southern species of birds are found here. In terms of vultures’ suitability, the area still has well preserved extensive livestock breeding and transhumance practice, where the herds are moved in the nearby high mountains Pirin and Rila, home to two of the three national Parks in Bulgaria. So it is the combination between deep valley with mild winters and high mountains with alpine pastures that makes the habitats suitable for vultures. Extensive livestock breeding and the presence of large carnivores like wolf and bear are additional benefits for the vultures. The last also poses a threat for the vultures, because the conflict between livestock breeders and carnivores some times leads to illegal poison baits use, which is the biggest threat for the vultures. We found that providing the feeding sites for vultures make it safer for them. Also, some people are concerned that it may be unnatural to feed vultures but because we dispose mainly of – although not only – food coming from the nearby villages, this makes the process rather natural.

Why was there a need to embark on a reintroduction process – how did the griffon vulture lose its place?

Since the beginning of the twentieth century the situation of the vultures of the Balkans and Europe became worse and worse based on extensive livestock breeding decline but mainly on direct persecution and non-deliberate poisoning. Not least the habitats changed especially in Bulgaria, where vast areas were reforested and thus the vultures no longer were able to search for and find food. In the 1960s nearly every available carcass for the vultures was poisoned and they went extinct from the entire country. In 1970 all large European vultures were considered extinct from the country. Only a small colony of less than 30 birds and 2-3 breeding pairs survived in Eastern Rhodope Mountains on the border with Greece. Although the conservation measures helped this colony to increase from 2-3 pairs to about 80 nowadays, the range of the species did not extend and still is only in Arda River Valley in Eastern Rhodopes. In the 1970s the large vultures were still surviving in Greece, but with time the bearded and griffon vultures have gone extinct from the mainland. The only black vulture colony in the Balkans is found in Dadia National Park in Greece close to the Bulgarian border. So we saw there is now suitable source of vultures where from they may recover naturally and that is why we decided to establish 5 new colonies – 4 to the north along the Balkan Mountain chain where we work in close cooperation with other NGOs such as Green Balkans and Bird of Prey Protection Society, and to the south west, Kresna Gorge. The last is also close to the small and declining population of the griffon vulture in FYR of Macedonia. But with the newly established colonies, it seems the situation gets a bit stabilized now. The summering, wintering and migrating birds on Balkans now have some more safe areas – read the book for the Reintroduction in Kresna Gorge to find how it works.

In short – if we want to have forests, wolves, but also vultures we have to reintroduce and organize feeding sites for them in our modern world dominated by man.

Reintroductions are quite a hot topic at the moment.  One of the main concerns is finding accord between conservationists, landowners and the public regarding the benefits of such actions. Was this a problem for you in Bulgaria?

This is manageable. Especially with friendly species like the vultures it is a small concern for the local people in the very beginning and then they just appreciate the lovely and gorgeous birds flying high in the sky. The proper communication and involvement with local people is crucial for the success of any such initiative.

What are some of the major challenges the team faced during the years of the project?

The development of the network for receiving in-time information about livestock carcasses was very important and it took quite some time. Establishment of the first nucleus of griffon vultures also was a challenge. We did it twice until we found what the most important thing is. It was the food that should be provided not only in large quantity, but also at the best place for the vultures, and in summer to be provided frequently in small amounts so as not to decompose.  We hardly learned that decomposed carcass is not an appreciated food source for vultures. They prefer fresh carcasses. Or at least not rotten meat. When we found that and made an effort to overcome it we saw the success.

Would you say that the process has been a success, then?

Yes, this is a success story. Of course we would like to see some more achievements in successful breeding and increase of the number of the breeding pairs of griffon vultures, as well as the return of the black and Egyptian vultures as breeders in the area. And one day also the return of the bearded vulture too.

Are there any lessons learned from this project that might have application for reintroduction practice in general?

Reintroduction of Griffon Vulture Gyps fulvus in Kresna Gorge, Southwest Bulgaria 2010-2015

There are two things: the vultures will not survive in the modern world without managing the carcass disposal. We could not have forests and wolves and also to have vultures just on their own. The last should be supported through feeding sites, at which the carcasses from the local villages and farms would be disposed and made accessible to vultures.

We developed a good method for individual identification of the vultures through so-called visual marking. We use cameras with long lenses and take pictures of every bird seen in flight. Then we compare the characteristics of the plumage. This way, even birds not marked with rings or wing-tags could be distinguished. The method is well described in the book.

If you could make one change to policy in Bulgaria, or beyond, that would be of benefit for vulture conservation, what would it be?

Reintroduction of Griffon Vulture Gyps fulvus in Kresna Gorge, Southwest Bulgaria 2010-2015

In the vultures’ range (either historical or current), where suitable habitats are still found, every natural or national park authority should be involved in maintenance of feeding site(s) for vultures. This should be one of the basic management practices for all protected areas that have an administration body. This way a large network (e.g  Natura 2000 sites) of vulture safe areas will be established and the coherence of the habitat and space restored.

Some adaptations of the legislation concerning poisoning of wildlife and domestic cats and dogs should be done especially in Bulgaria. The use of poison baits in natural environment should be treated as an act of hunting. Nowadays the Bulgarian legislation does not treat the poison bait setting for dogs and cats. Only if a game species and/or protected species is affected the law could be applied.

How are the vultures doing today, and what are the next steps, for the project, and your own work with the Fund for Wild Flora and Fauna?

The vultures are preparing for the new breeding season. They are now making the very attractive simultaneous flights as breeding displays and seem very much enthusiastic especially in warm and windy days.

The next step is the reintroduction of the Eurasian black vulture, within the frame of the new Bright Future for Black Vulture in Bulgaria project LIFE14 NAT/BG/649, in cooperation with Green Balkans, Vulture Conservation Foundation, EuroNatur and the regional Government of Extremadura. I hope in future a similar story and a book will be issued for the black vulture in Kresna Gorge and Balkan Mountain in Bulgaria, where the species is now extinct for more than half a century.

I would like to mention here my colleagues and friends that work hard for all this to happen – Hristo Peshev, Lachezar Bonchev, Atanas Grozdanov, Nadya Vangelova and Yavor Iliev.

Nature Classics Library: an interview with Jon from Little Toller Books

Jon Woolcott of Little Toller
Jon Woolcott of Little Toller at the publisher’s office in Dorset

Little Toller Books was established in 2008 as an imprint of Dovecote Press with the aim to revive lost classics of nature writing and British rural history. The success of their Nature Classics Library, has allowed them the independence to follow their inspiration in terms of the projects they pursue and they are now a leading voice in nature publishing. We asked Jon Woolcott of Little Toller Books about the Nature Classics Library.

The books are beautifully designed – what was the original inspiration behind the Nature Classics Library?

Thank you, that’s nice to hear – we work really hard at the design of the books, it strikes us that a book should be a beautiful object, and reflect the quality of the writing. The founders and co-owners of Little Toller, Adrian and Gracie Cooper, moved to Dorset but when they wanted to explore more about the country around their new home they found many of the books they wanted to read were no longer available. That inspired them to republish the great classics of nature writing – books like The Making of the English Landscape by W G Hoskins and The South Country by Edward Thomas. So Little Toller Books was born. The list has grown from there.

The Making of the English Landscape - W G Hoskins

With introductions by big name authors giving them great general appeal, are you hoping to bring these classics to a new audience?

Indeed – we’re not the first generation to rediscover these great books – and bringing authors like William Boyd, Robert Macfarlane and Carol Klein to them makes a big difference. We also use artists to complement the writing – the obvious example is Ravilious on our edition of The Natural History of Selborne by Gilbert White, but we use artists to illustrate our monograph series.

Eric Ravilious illustration fromThe Natural History of Selborne
Eric Ravilious illustration fromThe Natural History of Selborne

How do you choose the books that end up on the list?

We’re a tiny team (there are just four of us at Little Toller) so we work together but ultimately Adrian chooses the books – it’s based on his taste and a sense of what readers are looking for, but always with the goal of exploring nature and our relationship with landscape.

If you could gain rights to publish any book from the history of nature writing, what would it be, and why?

We’ve always got a wish-list on the go! We’d love to publish Tarka the Otter of course (we already publish Williamson’s Salar the Salmon) but a really exciting project would be to publish an anthology of Darwin’s letters recounting his explorations into his local area, and his relationship with his family. As yet, this remains in the pipeline though!

Salar the Salmon - Henry Williamson

Do you remember the first natural history book that you enjoyed?

At Little Toller we all have our favourites, books that made an enormous difference to the way we felt or thought about nature. Speaking just for me I would highlight a book we don’t (yet!) publish – Bevis by Richard Jefferies. It’s not really a natural history book – ostensibly it’s a children’s book in the Swallows and Amazons tradition but written earlier. Jefferies brilliantly articulates the feelings of a boy as he explores the landscape. Jefferies was an early exponent of what we now call nature writing and I remember being captivated by his style. Adrian would choose On the Origin of Species because it’s so important, but for pure enjoyment he would have to go for Gerald Durrell’s My Family and Other Animals (editorial note: available as part of The Corfu Trilogy).

What do you think characterises great nature writing?

Oh, that’s a difficult question – each writer brings something new – but it’s characterised by a deep understanding of the subject combined with wonderful writing. A sense of the personal reaction to the natural world is imperative – we don’t publish text books but instead those which bring the reader close to the subject.

Little Toller also publishes new writing, with Horatio Clare’s Orison for a Curlew just out. What are you looking for in potential new publications like this?

We look for originality, for subjects which readers will love, and for wonderful writing. It’s led us to publish Oliver Rackham, Iain Sinclair and Richard Skelton this year alone.

The Ash Tree - Oliver Rackham

What does the future have in store for Little Toller and the Nature Classics Library – any secrets you can let us in on?

We’re always looking to expand what we do – for instance we have two short films on our website about two of our books made by the authors – Iain Sinclair’s Black Apples of Gower and Richard Skelton’s Beyond the Fell Wall –  and Andrew Kotting made Iain’s film with him. We’re tiny so we can be really flexible in what we publish but we’re especially excited by In Pursuit of Spring by Edward Thomas – which will have Thomas’ photographs from 1913 taken along the journey, published for the very first time – coming in March next year. We’re also looking forward to Cheryl Tipp’s book on the sounds of the sea. Many of NHBS’s fans will know her – she’s the Wildlife Sounds Curator at the British Library. And we have new books in the pipeline from Tim Dee, Dexter Petley and Horatio Clare, as well as new Nature Classics from R M Lockley and others. We’re also continuing to put our monographs into paperback as we have just done with The Ash Tree. We’re very busy! But we’re enormously heartened by the reaction to our books.

Naturalist, artist and author Steven Falk on his new field guide to bees

Field Guide to the Bees of Great Britain and IrelandNaturalist and wildlife artist Steven Falk has had a diverse career with wildlife and conservation, including working as an entomologist with Nature Conservancy Council, and as natural history keeper for major museums. He is now Entomologist and Invertebrate Specialist at UK invertebrate conservation organisation Buglife. His new Field Guide to the Bees of Great Britain and Ireland will be published by British Wildlife Publishing next month.

Tell us about your role at Buglife.
At Buglife, I have quite a diverse role. I provide information and advice to colleagues, external enquirers and a plethora of external organisations. I’ve been particularly involved with overseeing the production of new red lists for assorted invertebrate groups, also providing feedback to the various national pollinator strategies, new agri-environment schemes, plus helping to develop projects for some of our most endangered invertebrate species. We also have a consultancy now, Buglife Services, which carries out and coordinates invertebrate surveys all over Britain. We’ve just done an exciting survey of the A30 and A38 in Devon and Cornwall. We need more understanding of road verge invertebrates, especially pollinators.

How did you come to write this landmark identification guide to all the bees of Britain and Ireland?
I was approached by Andrew Branson in 2012 and was initially quite reluctant, because you cannot use a traditional field guide approach for bees, as many cannot be identified to species level in the field (they require the taking of a specimen for critical examination under a microscope) and it is crucial that we keep the national dataset (run by BWARS) clean and reliable by being honest about where the limits of field identification lie. So I agreed to write it on the basis that it covered all 275 species, had reliable keys, and could appeal to both hardcore recorders and general naturalists. I knew this was feasible, because we had faced the same challenge with the seminal book British Hoverflies (Stubbs & Falk, 1983, 2002). So it is a field guide in the loose sense – it will help you to recognise much of what you see in the field, but also indicate at which point you need to take specimens and put them under a microscope. But you don’t need to collect bees or have a microscope to enjoy the book – we made sure of that.

Field Guide to the Bees of Great Britain and IrelandThere is growing concern about the conservation status of bees – how are our bees getting on, and how might the publication of this book help them?
Yes, we need to be concerned about bees. We have already lost 25 species and several more are teetering on the edge of extinction. Good bee habitat continues to be lost. Brownfield land came to the rescue last century, but most of that has now been developed or lost its flowery early successional stages, which is what so many bees need. The research being carried out on pesticides such as neonicotinioids is also pretty disturbing – check out the work by Prof. Dave Goulson at Sussex University. It seems to be affecting bee numbers in many parts of the country. The national pollinator strategies being published by UK member states are a call to arms – let’s get monitoring bees. But the emphasis is on developing citizen science to achieve some of this, because there is little funding. High quality amateur recording is part of this plan, and Britain’s strong tradition of this makes it a realistic proposition. But the last comprehensive coverage of British bees was Saunders, 1896, and it has been the lack of modern ID literature that has held bee recording back. Field Guide to the Bees of Great Britain and Ireland, and the supporting web feature (embedded in my Flickr site) will hopefully fix this!

Your career as a wildlife artist began early – you worked on the colour plates for Alan Stubb’s guide to British Hoverflies when you were just a teenager. How did this collaboration come about?
I pinned some bumblebees I had caught near my home in North London when I was 12. Half of them turned out to be bee-like hoverflies, and that started a fascination with hoverflies. The following summer holiday, I went out with a net almost every day, and seemed to find a new type of hoverfly daily. I was totally hooked on them, and I painted things that fascinated me, including those hoverflies. I exhibited some hoverfly artwork at the 1976 AES Exhibition in Hampstead, and met Alan Stubbs who told me he was writing a new guide to hoverflies. I said I wanted to do the artwork (I was only 14), and the rest is history. It took 3 years of evenings, and I think I was 17 when I finished it. I’m very proud of those plates, and you can see how my style develops (plate 8 was the first and plate 7 was the last – you can see a lampshade reflection in the early ones!).

Field Guide to the Bees of Great Britain and IrelandDo we see any of your artwork in this book?
Sadly not, my eyesight is not great these days and I do very little drawing and painting now. But the British Wildlife Publishing ‘house artist’ is the great Richard Lewington, and he’s done a magnificent job. The bumblebee plates in particular, are just stunning, the best ever produced.

What sort of techniques do you use to produce your artwork – which is strikingly realistic and very detailed?
I painted birds a lot as a young child and was very aware of the bird artists of the time and their styles, people like Basil Ede, Charles Tunnicliffe and Robert Gillmor. I particularly liked the detail and photo-realism of Basil Ede’s work and became aware that he used gouache. So I started to use gouache and preferred it to watercolour. I’d often start with a black silhouette and build up the colour and texture on top of this, which is the opposite of watercolour painting. But others, like Denys Ovendon and Richard Lewington, show what can be done with watercolour, so it’s just a taste thing. For really intense or subtle colours, I’d need to use watercolours, because they produce a much larger colour pallete than gouache. Richard knows his watercolours – you need to if you want to tackle butterflies like blues, coppers and purple emperors. I’m possibly more proud of my black and white illustrations than my colour work. Here I was most influenced by the likes A. J. E. Terzi and Arthur Smith, house artists for the Natural History Museum. Their use of cross-hatching and stippling is so skillful, and I’ve tried to emulate this in my pen and ink artwork. Never use parallel lines in cross hatching!

Any future interesting projects coming up that you can tell us about – artistic, or conservation-based?
There are many more books I’d like to write, especially for wasps and assorted fly groups. It’s not just the subject, it’s the approach. I like getting into the mindset of the beginner and finding the right language and approach. We need to get more people recording invertebrates. I like the double-pronged approach of books plus web resources, and I have a popular and ever-expanding Flickr site that greatly facilitates the identification of many invertebrate groups. On the conservation front, I’m keen to continue promoting understanding of pollinators and to increase the effectiveness of agri-environment schemes. Invertebrate conservation is in my blood and I’ll be pursuing it to the very end in one form or another. I might even try illustrating again one day if I can find the right glasses!

Interview with botanist James Byng, author of The Gymnosperms Handbook

James Byng
James Byng in Zambia looking for Syzygium

James Byng is the author of the new Gymnosperms Handbook and a founding member of Plant Gateway, the botany organisation that published this, and his previous book, The Flowering Plants Handbook (out of print – new edition pending). In this interview he tells us about his work with Plant Gateway, raising the profile and accessibility of plant research, his own work with the genus Syzygium, and a day in the life of a working botanist.

You are a founding member of the Plant Gateway team. What is the vision for this botany organisation?

Taxonomic research is an underfunded and underappreciated branch of science and so few plant taxonomists are employed today in universities, and most national botanical institutions are cutting staff. However, the need to document the world’s species diversity has never been greater with as many as a fifth of all known plant species estimated to be threatened with extinction.

We believe at Plant Gateway an important step in slowing the biodiversity crisis is making plants more relevant and more accessible to people. It sounds simple but plant research in general is never quite appreciated as much as research on animals or in other scientific disciplines. But plants are fundamental for our own existence and continued survival on this planet, and we still barely know anything about most of them. Plant Gateway was founded for passionate like-minded taxonomists to make sense of the complicated botanical literature by publishing practical literature, running affordable and engaging identification courses, and undertaking taxonomic research with the aim of bringing it to a wider audience and making significant strides in our knowledge.

Who are the Plant Gateway courses for and how can they get involved?

Whilst training to be a plant taxonomist I witnessed over the years that plant identification skills were rarely being taught at universities anymore despite there still being a huge demand. Even though several courses exist which teach these skills, many of the courses are very expensive and/or taught too much from the specialist’s point of view which scares people off. Our courses are designed for everybody and anybody whatever a participant’s botanical background – all you need is an interest and love for plants! On past courses we have had undergraduate and postgraduate students, university professors and lecturers, horticulturalists, ecologists, Friends of Botanical Gardens and gardeners. We run several 1-day identification courses all over the UK in May and June, and a week long course in Tenerife around Easter time in 2016. Places on these courses can be reserved on our website.

The Gymnosperms Handbook: A Practical Guide to Extant Families and Genera of the World

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The Gymnosperms Handbook is the second publication from Plant Gateway. Who is this book aimed at?

The Gymnosperms Handbook is a concise introduction to identifying extant gymnosperms of the world. It is aimed at both specialists and non-specialists; ranging from experienced botanists, ecologists, horticulturalists, biologists and gardeners to students and those people who are learning about and interested in conifers, cypresses and other gymnosperms because they see them in their local parks and forests. So the handbook is aimed for everybody whatever their background.

Part of your own research is focused on the systematics of Syzygium (Myrtaceae). What led you to this particular genus?

In 2007 I was an undergraduate at the University of Aberdeen when I first encountered the genus Syzygium in Zambia while undertaking ecological fieldwork. Since then I have been intrigued by the genus as most botanists seem scared by the sheer number of (known and unknown) species and the difficulty in identifying them due to the seemingly poor diagnostic characters which separate species. The genus is famous for containing the commercial clove (Syzygium aromaticum) and is now the largest tree genus in the world with over 1,200 species. I am now leading a project, with collaborators in the USA, Australia, Africa and Asia, to unravel evolutionary relationships of Syzygium and to document all species in a global monograph.

What does a working day as a botanical researcher look like for you?

A typical working day for a plant taxonomist in the twenty first century varies from week to week. Most of my time is spent with dried plant collections, housed in herbaria, where I sort through specimens collected from past and present field expeditions and document and describe species diversity. I also spend time collecting new data and plants in the field, usually in the tropics, and undertaking lab work where I extract and amplify DNA to understand evolutionary histories. Lastly, but perhaps most importantly(!), I spend time in front of the computer writing up my findings in the form of scientific papers, reports and books. It can be a combination of enjoyment and stress but once I finish a piece of work it makes it all feel worthwhile.

What’s next in line for publication from Plant Gateway?

One of the next titles in our practical handbook series will be a revised second edition of The Flowering Plants Handbook which will include notes on all flowering plant genera, more images, and will follow the soon to be published Angiosperm Phylogeny Group (APG) IV classification system. Also, there will be a practical handbook on ferns and their allies co-authored with my Plant Gateway colleague, and leading fern specialist, Dr Maarten Christenhusz.

Sweden’s first regional dragonfly atlas – interview with author Tommy Karlsson

Tommy Karlsson, author of Östergötlands Trollsländor [Dragonflies in Östergötland]
Tommy Karlsson, author of Östergötlands Trollsländor [Dragonflies in Östergötland]
Congratulations on the book and on publishing the first regional distribution atlas for dragonflies in Sweden. What is your background in natural history? Have you always been interested in dragonflies?
Thank you very much! I am a biologist and work since 2005 at the department of Nature Conservation at the County Administrative Board of Östergötland, mainly with action plans for threatened species. I have always been interested by natural history, and as a kid I liked to collect larvae of dragonflies, stoneflies, mayflies and other limnic insects. However, my interest for imago dragonflies and identification of species started during my biology studies, about 2002-2003.

For those who may not be familiar with the natural history of Sweden, what sort of place is Östergötland in terms of biodiversity and landscape?
Östergötland is situated in south east Sweden and covers 14,500 km sq. It is situated in the boreonemoral vegetation zone and can be divided into four natural geographic regions: the southern woodlands, the plains, the archipelago, and the northern woodlands. The woodlands and the archipelago mainly consist of coniferous forests, while the plains mainly consists of intensively cultivated agricultural land. The woodlands have great numbers of lakes and mires, while the plains are very poor in water. The main part of Östergötland is lowlands, but in the southern woodlands there are considerable areas above 200 m.a.s.l. The bedrock in the county is mainly acid but in the western part of the plains there is an area of Cambro-silurian calcareous rock. During the last glaciation, calcareous material was dispersed southwards, resulting in calcareous soils in some parts of the southern woodlands with granite bedrock. As a consequence of bedrock and soils you find mainly oligotrophic and dystrophic waters in the northern woodlands, eutrophic waters in the plains, and a mix of oligotrophic, dystrophic and mesotrophic in the southern woodlands. Östergötland, along with other southeastern regions, is one of the most species-rich regions in Sweden considering invertebrates due to its relatively warm and dry summers. It is well known for its considerable areas with hollow oaks and the saprolyxic fauna and flora associated with them.

How do you co-ordinate a project like this, with 150 volunteers over the course of five years (2008-2012), and what were some of the highs and lows?
It worked out very well since all was based on voluntarism. After getting initial information about surveying and identifying dragonflies, the participants could work quite independently. Most of the communication with the participants was made through e-mail. In addition, several activities were organized: kick-offs every spring, survey courses and excursions during summer, and reporting courses during fall. Many of the participants had no experience of surveying dragonflies before, and the fact that we managed to get so many volunteer amateurs out surveying dragonflies was one of the highlights of the project. Furthermore, the participants were a heterogenous group in terms of age and gender, and not only older men which is common in entomological contexts.

In the study you make comparisons with 10 other regions in Europe. What conclusions have you been able to draw through these comparisons?
Yes, I compare Östergötland with some other European regions where dragonfly surveys have been performed. Most of the regions have more species than Östergötland because they are situated south of Östergötland. On the other hand, Östergötland has two species which generally are missing in the other regions: Coenagrion johanssoni and Aeshna serrata. When comparing the species the regions have in common, the frequency for some species differs a lot between Östergötland and the other regions. Östergötland is distinguished by the fact that species classified as red-listed and/or decreasing in Europe occur more frequently in Östergötland than in most of the other regions. Particularly Coenagrion armatum and Leucorrhinia caudalis can be pointed out as much more common in Östergötland. Thus, Östergötland has both a national and international responsibility for these species, together with A. serrata, Aeshna viridis and Nehalennia speciosa. The reason for this is that important habitats for these species, such as bog ponds and mesotrophic lakes are naturally more common in Sweden, and that the exploitation of waters in Sweden has not been as severe as in central Europe.

What were some of the other significant findings of the project?
Probably because of global warming there is an ongoing change in the European dragonfly fauna where several southern species have expanded rapidly northwards and some northern species have retreated. In Östergötland the establishment of Lestes virens and Ischnura pumilio has been documented during the survey. L. virens was observed for the first time in the county in 2005 and, during the period 2008-2012, was found at several new localities every year. I. pumilio was first noted for the Östergötland in 2012.

And what is next for you and for the Östergötlands Entomological Society?
This year I have got the assignment to co-ordinate Sweden’s monitoring of the dragonflies species listed in the EU’s habitat directive. It will be very nice to work professionally with dragonflies and I have learned a lot about these species and dragonfly monitoring during the survey in Östergötland. I started this work last week with a field study of Ophiogomphus cecilia, a species only occurring in some few unregulated rivers in the very far north of Sweden. Concerning the Entomological Society in Östergötland, we have discussed the possibility of starting up another voluntary survey of some other easy identified insect group, e.g. shield bugs or grasshoppers, but nothing is ready to start yet.

Ecologist Derek Gow on beaver reintroductions in the UK

Ecologist Derek Gow (The Derek Gow Consultancy) is the co-author of The Eurasian Beaver, published in January 2015. His involvement with Devon Wildlife Trust’s trial reintroduction and the Tayside beaver reintroduction makes him uniquely placed to discuss the topic of beaver reintroductions in the UK.

The Eurasian BeaverHow would the presence of healthy beaver populations enhance the UK’s landscape and biodiversity?

In Eurasia and North America beavers are the keystone species around which all other wetland life revolves. Their simple dam building and tree felling activities trigger a whole range of complex changes in their surrounding environments which clearly result in greatly enhanced levels of biodiversity and biomass. In landscapes which are semi-natural the cascade of dynamic changes they produce harbours the potential for breathtakingly spectacular results, such as the return of the black stork. While in highly manipulated, human engineered environments they can literally breathe life back into the land.

You are involved with the Devon Beaver Project, which has created a test environment to see how reintroduced beavers would affect their local ecosystem. Can you tell us more about this project, and what results it has produced so far?

The initial stage of the Devon Beaver Trial was designed to evaluate from ground zero the impact of a beaver family in an enclosed area of wet-woodland of approximately 3ha. Between 2011 and 2015 the beavers created a series of approximately 14 major dam systems on a 200 metre length of a seasonally flowing water course at the northern end of the site. They maintain long dams in the winter when water is abundant and short dams in the summer when water is scarce. At the time of writing their impoundments are capable of retaining approximately 1000 tonnes of water, none of which would have seasonally remained on site without them. The return of the beaver has been accompanied by a proliferation of wildlife. Flowering and other vascular plant communities now abound on site. On warm sunny days meadow browns, marbled whites and a host of other butterflies flit through its open woodlands. Dragonflies and damselflies occur in ever greater numbers while amphibians such as common frogs have increased in numbers fiftyfold. Juvenile common lizards hunt through the deadwood understory while marsh tits, spotted flycatchers, greater spotted woodpeckers, tree creepers and redpolls hunt insects in the trees. Water fowl have moved into occupy environments which formerly did not exist. Red and roe deer jump the perimeter fence to drink in its pools.

It is an absolutely amazing project and a brilliant site.

What does a reintroduction look like in practical terms? Can you break down the logistics of species reintroduction?

Well if you ask the Germans its simple: you get lots of beavers – 40 plus per release, drive along the road, spot a likely location, and let them go. A crude system which works! Reintroductions in Britain are often subject to a large degree of politics, which can be frustrating as this is a species well understood throughout its natural range which simply offers so much. We could do much better. To date, beaver reintroduction has been a haphazard affair with major public spats between those that wish them to remain and those that are opposed – the history of the Tayside and Devon beavers demonstrate this well. Given that this species was last present in Britain outside of our living memory, it is assumed that licensed releases require a scientific demonstration of how this animal will impact a British landscape – as though it will be any different from what our European and American counterparts have already demonstrated. In realistic terms, in Britain an official reintroduction would involve a small number of animals, released into a specific site, with thorough scientific monitoring of impact and public opinion. Though we may take heart that beavers are now back in our landscape, the process to full restoration is likely to be slow and cautious.

What precedent does the approval of the River Otter beaver population set for reintroductions as a wider concept? Are we likely to see lynx roaming wild any time soon?

We need to learn to live with and tolerate beavers before I think we can accomplish anything more adventurous in Britain. If we can’t move forward with reintroducing this charismatic rodent that has such significant impacts on its environment, and can single-handedly do so much to restore our wetlands, then we need to be seriously realistic about our collective ability to accept top predators on this island – no matter how nostalgic or headline grabbing the notion of lynx may be.

What would you say to people who consider reintroduction to be somehow against the natural order of things?

When you consider our contemporary British landscapes and their land-use practices, which are entirely dictated by human activity, they represent little in the way of natural order. In truth they are not ecosystems and we are probably grasping at straws to even describe what’s left as tattered fragments blowing in the wind. Instead we have a wealth of isolated areas of biological richness, generally produced as a result of relict human activities which are difficult to maintain and increasingly vulnerable and fragile. Do we accept that these nature zoos are it, or do we try to foster and encourage a process whereby we change the pattern of the landscape we have made to make it better for people and wildlife alike? Reintroductions, where human activities have caused the past extinction or diminution of a species in Britain, are simply a tool we should employ with competent ease where the circumstances justify its use.

We recently heard the news about the successful litter of kits produced by the River Otter beavers. What did this news mean to you personally? 

Brilliant!! It’s been a long time coming. Let’s move on now from these vital but small and isolated pockets of beavers and see the full restoration of this incredible species.

On the importance of pollinators in East Africa: an interview with Whitley Gold Award winner Dino Martins

Dino MartinsDr Dino Martins is an entomologist and evolutionary biologist with a PhD in Organismic and Evolutionary Biology from Harvard University. He is also well-known in his native East Africa where he works to educate farmers about the importance of the conservation of pollinators. It is this work that recently won Dr Martins the prestigious Whitley Gold Award presented by the Friends and Scottish Friends of the Whitley Fund for Nature. His book, The Pocket Guide to the Insects of East Africa has just been published by Random House Struik. What’s more, he takes great photos, the majority of those in the book being his own.

Congratulations on winning the award – how did you become involved in entomology, and what does this award mean to you personally?

I am very honoured and deeply humbled – I take this award as recognition for the immense contribution by pollinators (mainly insects) and small-scale farmers in rural areas around the world to biodiversity. So I am receiving it I feel on their behalf. My earliest memories are of insects, as I spent a lot of time watching and chasing after them as a child. This award will enable me to scale up our work on the conservation of pollinators in East Africa, and also raise further awareness among farmers, school children and the general public on how this important ecosystem service puts food on our plates and nutrition in our bodies.

You  work extensively with the East African farmers, educating them about the importance of pollinators for healthy crop yields – what is your main message to them?

Our main message to farmers is to celebrate the biodiversity that underpins the life support systems of the planet. Farmers are our greatest allies in the conservation of biodiversity in East Africa. Most of the forest habitats, for example, are surrounded by small-scale farmers whose actions can go a long way to either protect or degrade the forests, and of course the many endemic species they are home to. We want to get farmers and everyone to understand the connection between their own lives, food production and wild insects. We do a simple experiment where we bag one flower and leave one open to insects, then watch what develops over the next few days or weeks depending on the crop. It is always uplifting to see the moment a light goes on in the farmers’ eyes when they see the connection between insects visiting the flowers and the yields they enjoy. Working to help conserve pollinators and restore habitats has seen yields increase up to ten-fold on some crops, such as passionfruit and watermelon.

Entomology may be perceived as a less glamorous area related to wildlife conservation, but it is so essential globally – what is the appeal, and the importance of your field for world biodiversity?

As Professor E. O. Wilson stated so eloquently some time ago: “Insects are the little creatures that run the world”. This is more true than ever in Africa where the large mammals are important, but also depend on insects that pollinate wild plants, disperse seeds, help build soil and recycle nutrients through the whole ecosystem. Understanding biodiversity is essential for sustainable development and conservation in Africa today. I feel that we are uncovering a previously ‘hidden’, somewhat unrecognised sphere of biodiversity: that of the rural farming landscape. When farmers create hedgerows of natural plants, protect patches of forest or grassland, or work together to create on-farm habitats we are finding that some of these landscapes are especially rich in pollinators. For example, on one mango farm in the Kerio Valley we have recorded over 1,000 different species of flower-visiting insects. This farmer harvests up to 12,000 mangoes weekly that earn him thousands of dollars. Without pollinating insects there would be no income on this farm. Watermelon farming brings in over 10 million US $ annually to just one county (Baringo) in Kenya’s Rift Valley. Scaling this up globally means that a huge part of our food production and especially high-value crops like nuts and berries are dependent on wild insects.

Do you feel confident that enough is being done to protect our pollinators?

There is a lot of interest in pollinators today that has come about from regional initiatives, including the Global Pollination Project managed by the Food and Agricultural Organisation of the United Nations. There is also an on-going assessment of pollinators by the IPBES (I am a coordinating lead author for one of the chapters). Locally, many farmers, gardeners, beekeepers and enthusiasts are working to create habitats, provide nesting sites and learn about the pollinators around them. This is very inspiring and heart-warming to see. In East Africa, where we have a huge diversity of bees and other insects, one of the challenges is actually just identifying them, and this is where we are working with farmers – so that they can recognise that the diversity on their farms is of direct benefit to them and their families. Major challenges remain in terms of better understanding and managing pesticides and also farming in ways that are compatible with nature while scaling up food production worldwide.

pocket insects east africaWhat is coming up for you next, following this award, and the publication of your book, Pocket Guide to the Insects of East Africa?

I am back in Kenya now after an amazing few weeks in London. I am very much looking forward to getting back into working with farmers and completing a number of other books including ‘The Bees of East Africa: A Natural History’, and ‘The Butterflies of Eastern Africa’ with Steve Collins. A book we launched digitally on pollinators is also due to be printed shortly, but can also be downloaded here.

The Pocket Guide to the Insects of East Africa is being very well-received here and abroad, and I have had hundreds of messages saying how exciting it is to finally have a book on insects for the region. On the work front I have just been appointed the Director of the Mpala Research Centre in Laikipia, Kenya and am looking forward to getting more entomology projects going there.

Anne Bebbington on botanical illustration and her new book, Understanding the Flowering Plants

Dr. Anne Bebbington trained as a botanist and worked for over 30 years for the Field Studies Council and as an environmental educator. Also an outstanding botanical illustrator, her career has traced a path between the two complementary fields, and she is a past President of the Institute of Analytical Plant Illustration.  Her new book is a testament to this dual expertise.

What came first for you, botany or illustration – and how have the two interwoven throughout your career?

From an early age natural history, drawing and painting were always my favourite occupations. At university I was lucky to be able to study both botany and zoology and found that drawing the plants and animals we studied was for me the best way of describing and understanding them. After specializing in plant ecology I joined the Field Studies Council. As well as teaching environmental studies at all levels from primary pupils to undergraduates, I tutored many wild flower courses for adults both in Britain and further afield in Europe, Canada and Australia. My interest and expertise in illustration always formed an important part of my work, particularly in producing handouts and identification aids, and running short botanical illustration courses. In retirement I work as a freelance natural history illustrator but also continue to share my enthusiasm for plants running workshops and giving talks to both natural history groups and garden clubs.

You are a founder member and past President of the Institute for Analytical Plant Illustration. Tell us more about this organization?

The Institute of Analytical Plant Illustration (IAPI) promotes interest in the diversity and understanding of plants through illustration. It was founded in 2004 by the late Michael Hickey, an excellent teacher, botanist and skilled analytical illustrator. Its aim is to encourage and facilitate collaboration between botanists and artists by organizing talks, running workshops and field meetings, and setting up projects which members can contribute to.

In 2010, with IAPI support, I got together with Mary Brewin, a skilled artist, to provide a course of ten workshops combining botanical tuition with an opportunity to develop and practice appropriate illustration techniques. We hoped it would help members to:

  • gain a better understanding of plants to inform their practice of the art of botanical illustration.
  • develop and refine illustration techniques appropriate to different botanical subjects.
  • encourage enthusiastic beginners to gain botanical knowledge and some basic art skills.

This course was very successful and raised great interest and in the last four years has resulted in the running of further courses and workshops both for IAPI and other groups and organizations.

What is the place of botanical illustration in scientific research?

Botanical illustration both in the form of photography but also drawings and painting is integral to all aspects of scientific research.

Are there any botanical subjects that you are particularly inspired to work from?

I am particularly interested in the way that plants interact with their environment and how the intricacy of their structure plays a part in their success and survival. I frequently work with my husband, a zoologist and photographer, investigating the interactions between plants and animals, particularly insects. Close observation and drawing plants out in the field is also something I really enjoy.

What are you currently engaged with in terms of your botanical illustration career?

I am currently looking at the detailed internal structure of flowers in relation to their pollination mechanisms by producing illustrations in the form of half flowers.

It’s a beautiful book and a wonderful resource for botanical information – who is the book written for?

The book should be accessible to anyone, even those with little or no scientific background. It was written for:

  • botanical artists and photographers  who wish to gain a better understanding of the Flowering Plants to inform their practice of the art of botanical illustration.
  • anyone who works with or just enjoys plants and wants to know more about them.

Understanding the Flowering Plants: A Practical Guide for Botanical Illustrators is published by Crowood Press and is available now.

Brock Fenton on the mystery and science of bats

Bats: A World of Science and MysteryBrock Fenton is Professor Emeritus in the Department of Biology, Western University, Ontario, Canada. His research programme involves using bats to explore the interfaces between animal behaviour, ecology and evolution. As co-author of the exciting new book, Bats: A World of Science and Mystery, we thought it would be interesting to pose him a few bat-related questions:

How did you become involved with bat research as a career?

As an undergraduate student I was attracted to bats by the abundance of things to learn about them. Part of this I experienced by looking in caves for hibernating bats that had been banded elsewhere. The other part was the library, books about bats (Bats by G.M. Allen; Nerve Cells and Insect Behaviour by Kenneth D. Roeder) and articles in journals. My main research focus now is on bat evolution, behaviour and echolocation.

In evolutionary terms, what is a bat, and how have they come to represent around 20% of all mammal species?

Bats are mammals capable of powered flight. Flight gives them mobility and their small size makes them inconspicuous. Bats fill a variety of trophic roles as consumers of insects, plant products, as well as other animals (from fish to other bats and birds), and even blood. I suspect that a combination of mobility, small size and flexibility is responsible for their evolutionary success. The blood-feeding vampire bats are among the best examples of this success.

Is it possible to define the character of a bat, and a typical day in the life?

I had not thought of “character”. Bats are mainly nocturnal, so operation at night is a key characteristic. They are long-lived (some species over 30 years in the wild), and high energy, requiring large quantities of food to fuel their activities. Although bats typically emerge (from their daytime roosts or hiding places) at dusk, they probably come and go from their roosts during the night. In the northern hemisphere and some other temperate parts of the world, bats use delayed fertilization to ensure that young are born when food is abundant.

The title of the book includes the word ‘mystery’ – what do we remain in the dark about regarding these nocturnal creatures?

There are about 1260 species of living bats. The largest weigh about 1500 grams, but most species are under 50 grams.  Bats survive because they are hard to find by day. The combination of secretive and small size makes most species of bats hard to study. This means that people who study bats regularly make astonishing discoveries about them. In spite of some concerns about the possible role of bats in public health, most species have no direct impact on humans. Lack of direct connection to humans means that bats are sidelined when it comes to some main stream areas of interest, particularly those relating to human health.

What are the world conservation priorities for bats at the moment, and can you highlight any projects that are doing interesting work?

Bats are “typical” wildlife, mainly negatively effected by the habitat consequences of expanding human populations and demand for resources. In Northeastern North America, White-nosed Syndrome has killed literally millions of bats. Around the world turbines at “wind farms” also kill bats, but not on the scale of WNS. Research into White-nosed Syndrome and bats’ responses to turbines are important for the future of bats. Other research into the role that bats may play as reservoirs for diseases also is important for the image of bats. The last part of the book speaks about some of the unanswered questions about bats that appeal to the authors.

Who is this book aimed at?

We hope that this book will appeal to anyone interested in biodiversity and natural history. This could be the person interested in evolution or echolocation, conservation or social behaviour. We also hope that it appeals to those intrigued by flight, by where bats live and what they eat. It is not intended to be a text book about bats.

Birds and Climate Change – authors James Pearce-Higgins & Rhys E. Green discuss the impacts and responses

Birds and Climate Change: Impacts and Conservation Responses has just been published by Cambridge University Press. This key topic is given a broad critical review by James Pearce-Higgins, a Principal Ecologist at the British Trust for Ornithology, and Rhys E. Green, Principal Research Biologist at The Royal Society for the Protection of Birds and Honorary Professor of Conservation Science at the University of Cambridge. We asked them a few questions about the priorities and processes involved.

Birds and Climate Change: Impacts and Conservation ResponsesGiven this is such a vast subject, is it possible to summarize what we know currently about the impacts of climate change on birds – and also how we know it?

There has been an increasing wealth of scientific information published in recent decades, documenting the impacts that climate change has had on birds, which we review in the first part of the book. One of the best documented impacts is that the timing of spring migration and breeding outside of the tropics has become earlier in response to warming. There is also strong evidence that the abundance within bird populations has changed in response to changes in climatic variables through time. This has occurred through a range of different mechanisms. In response to climate change, these processes have led to significant changes in the composition of bird communities through time, and to shifts in species’ distributions, which have tended to move poleward by an average of over 7 km per decade.

The precise impacts of climate change vary across the globe, with changes in temperature being much more important in temperate and higher latitudes, whilst variation in rainfall is the most important cause of change in the tropics, and to long-distance migrants. Although there is a burgeoning evidence base about climate change impacts on birds, much of this research is from Europe and North America. We show in a key graph how little research effort there has been in the tropics, where we have shown the ecological processes are different, and where the majority of bird species are found. Long-term monitoring of bird populations, breeding and migration are an important resource for climate change studies. These studies have been done both by volunteer enthusiasts and academics, but mostly in the Northern Hemisphere and outside the tropics. Addressing this monitoring and research gap should be a high priority.

Much of the long-term monitoring data required to study the impacts of climate change upon birds is necessarily collected by volunteers (citizen scientists) because this ensures that the data are sufficiently extensive and sustainable in the long-term. Thus, information about the changes in the timing of migration and breeding is collected through bird observatories and schemes like the BTO’s nest record scheme, whilst large-scale information about bird populations and distributions is collected by standardised monitoring by volunteer birdwatchers, such as through annual breeding bird surveys and periodic atlases. Ringing (banding) and nest record schemes provide information about birth and death rates, which can help identify the processes behind these changes. These data are complemented by professional studies which are often more intensive and particularly have helped to understand the ecological mechanisms of change.

What sort of conservation responses are available?

The second part of the book examines potential conservation responses to climate change. The first step in this is to predict the future impacts of climate change on birds, which is covered by its own chapter. Here we link projected range changes and extinction risk to the amount of climate change, and show that increasing amounts of climate change will threaten an increasing number of species. We then review the options for adapting conservation action to climate change, building on a range of tools already used by conservationists. These include deciding which species and places are priorities for conservation, the protection and management of a network of core sites, habitat protection and creation to enhance connectivity, management of the wider landscape to reduce other threats and more intensive methods such as translocations. We believe that it is important to build on the foundations of existing conservation management, so that the threat of climate change does not divert resources away from existing and important conservation action. Reducing the impact of other threats on species will increase their ability to cope with a changing climate and may be sufficient, in some cases, to compensate for the negative effects of climate change.

Maintaining and extending the existing protected area network, alongside initiatives to improve the management of sites in that network, will be vital in helping species adapt to climate change. For example, protected areas can provide opportunities for colonisation of areas where the climate has become suitable for a species because of climate change. However, we recognize that with increasing magnitude of climate change, this adaptation challenge will become more difficult, and require more radical solutions. The final chapter in this section also considers the additional complication that the ways in which greenhouse gas emissions are reduced, and other climate change mitigation, will also have a significant impact on bird conservation. Some renewable energy options are likely to have negative impacts on birds, whereas prevention of the release of carbon stored in forests and bogs because of inappropriate land use change, such as deforestation and drainage, is likely to be beneficial for the bird species which inhabit those habitats.

Can you give some specific examples of responses underway, and what sort of levels of success these are demonstrating?

There has been recent criticism that because climate change will result in shifts in where species are found, that a static network of protected areas will no longer be useful. However, a number of recent studies are reviewed which demonstrate that by protecting large areas of extensive semi-natural habitat, protected areas in fact ensure the existence of suitable areas of habitat for species to move into. This has been particularly demonstrated for wetland and heathland nature reserves in the UK. There has also been much discussion about the potential for the creation of stepping stones and corridors to help create more connected landscapes through which species may move more easily. This literature is also discussed, which demonstrates that these interventions may benefit 30% of bird species studied, or fewer. Indeed, for the most sensitive habitat-specialists, such as tropical forest specialists, about 50% of a landscape may need to remain forested to ensure connectivity. Evidence is also building for the potential to manage sites appropriately to increase their resilience to climate change. In particular, the blocking of drainage ditches in the UK uplands may raise water levels and reduce the vulnerability of peatland ecosystems to summer drought, which will benefit a range of upland bird species, such as the golden plover.

Global change demands global responsiveness – how much agreement is there over the priorities?

Priority setting will be an important aspect of conservation responses to climate change, and a range of different ways in which priorities may be assessed exist. We review a number of these in the book, as well as suggesting a number of ecological traits likely to be associated with species vulnerability to climate change. Whilst there are an increasing number of examples of these being applied to particular regions or countries, there remains a lack of consensus over priorities across continents or biogeographical areas. The need to address this is recognized, and as discussed in the chapter on conservation in a changing climate, there is potential to use existing policy instruments, such as intergovernmental agreements, to achieve this. Given the potential threat that human responses to climate change may also pose to birds, whether the impacts of renewable energy generation, or other potential changes in land-use and other sectors discussed briefly in the final chapter of the book, this consensus needs to extend to other areas in order to be effective.

What future developments are on the horizon in extinction risk assessment, and are you positive about the potential impact of conservation responses overall?

One of the most significant chapters in the book reviews the literature predicting the effects of climate change on birds, and provides guidance for how this should be used. There is considerable potential to extend these to include information about population size, rather than just occurrence, and to make them more process-based, incorporating information about demographic rates and the mechanisms by which climate change may affect the species of interest. This has been achieved in a small number of cases, producing models which may be useful to inform future decision making about conservation responses to climate change. Such development will be particularly valuable, because it will help to assess the likely potential impact of conservation responses, relative to the likely magnitude of future climate change. However, this detail comes at a cost, and will not be feasible for most, or even many species.
