Author’s Foreword and Acknowledgements

HOWEVER OFTEN YOU go to Scilly it is still a magical experience as the islands slowly emerge out of the line of clouds on the horizon, to resolve into a mass of shapes and colours against the sea and sky. Whether you go there by boat, stealing up gradually on the islands, or by air, flying in low over the coastline of St Mary’s to land with a rush on the small airfield – like one of the plovers that feed there on the short turf – it brings a thrill of excitement every time.

I first went to Scilly in 1958, to stay at the St Agnes Bird Observatory that had started up the previous year. It was an ‘un-manned’ observatory, run by a committee of enthusiastics, organising self-catering holidays for groups of bird-ringers to operate it as a ringing station over the spring and autumn migrations. The first year had been based in tents at Lower Town Farm, but by the time of my visit they were renting the empty farmhouse. Like many similar establishments they ran on a small budget and lots of commitment; the living conditions were very basic, but the surroundings idyllic. That first visit was the start of a lifetime love affair with Scilly, which has influenced my whole adult life and has led to writing this account of the natural history of the islands.

Those early visits were made when I was working as a very junior scientific assistant at the British Museum (Natural History) in South Kensington. At that time collecting specimens was still an important element of the work, in order to build up the Museum’s taxonomic collections. So staff holidays often became unpaid collecting trips, and mine were frequently timed to go to Scilly at the best times for ‘shore collecting’, to collect marine invertebrates. These were when the equinoctial spring tides occur, around Easter and again in autumn, when the most extensive areas of shore are exposed. This was in the days before cheap wet suits and underwater photography meant that marine biologists were no longer constrained by tides. At that time it was boulder-turning and wading and following the tide down to the lowest level accessible, laden with heavy collecting gear. Most of the collecting I did was to order: specific groups of animals were targeted because these were ones where information on their distribution and status was needed, as well as adding representative specimens to the Museum collections. This resulted in a series of Isles of Scilly collections in the 1960s and ’70s, mostly shore fishes, sponges, worms, and other invertebrates, especially echinoderms, my specialist group.

Even after I had left the Museum, a colleague would send a small milk churn packed with collecting paraphernalia to the island of St Agnes to await my arrival for the family holiday, and then we would return it with the carefully preserved and labelled specimens packed inside. This system usually worked very well, but in the early days there were some hiccups – like the time the churn was nearly dispatched to Sicily due to a misunderstanding with the carriers, or the year it was put back on the launch by a puzzled islander because he did not know anyone who used milk churns on the island!

This first-hand experience – firstly the shore collecting, then the species records when collecting specimens became unfashionable, my involvement with the bird observatory, and then starting listing plants – was fortuitous in that it gave me a unique opportunity to study, photograph and get to appreciate the wildlife, scenery and history of these enchanting islands. I have been fortunate in that I was also to spend many weeks over the succeeding years on Scilly, usually based on St Agnes, and later St Mary’s.

Since those early days I have visited the islands at least once every year (except for a break of a couple of years in the late 1960s), have had several prolonged stays, and have been there in every month of the year and probably most kinds of weather. This has probably been the best way of getting to know as much as possible about the islands without being resident there. At various times I have been employed to survey and produce reports on a number of subjects from bats to plants. In 2002 I was commissioned to write a Management Plan for the land leased by the Isles of Scilly Wildlife Trust. This gave me a further opportunity to spend a longer time on the islands, getting to know them, their habitats and the people whose job it is to manage those habitats (Parslow, 2002).

Due to the climate and the geographical position of the islands there are some species, particularly plants, which are not usually easy for the holiday visitor to see. Certainly if you want to see some of the plants which flower in the middle of winter, such as some of the introduced aliens, German ivy Delairea odorata and some of the Aeoniums, then a visit at Christmas or New Year is essential. This is also a good time to find the tiny least adder’s-tongue fern Ophioglossum lusitanicum, a great rarity found in Britain only on the Channel Isles and on St Agnes in Scilly. Every month has its specialities, so there is always something to look out for at any time of the year. If your interests are more ornithological then everyone will recommend the spring and autumn migrations for the ‘falls’ of unusual migrants. In summer there are breeding seabirds, and a boat trip can take you out to see puffins, shags, guillemots, fulmars and other seabirds among the uninhabited islands – and there are also grey seals hauled out among the distant rocks. Even in winter there are peregrine and raven to look out for, and sometimes in cold weather large numbers of woodcock seem to fall out of the sky. For the other natural history groups, lichens, insects, fish or seaweeds, there are nearly always things to do and things to see!

It is not possible to write about the flora and fauna of the Isles of Scilly without considering all the other aspects that go to make them so unique. Their geography, geology and climate are intimately bound up with the history of the people of the islands, the way they have used the land, and present-day management. Over the next few chapters we will consider many of these aspects of the islands, as well as the major habitats found in Scilly – the heathlands, coastland, cultivated fields and wetlands. Each of the islands has its own unique character and special plants and animals – from St Mary’s and the inhabited smaller ‘off-islands’ to those uninhabited islands and rocks which are home to the rest of the islands’ wildlife. Then there are those people who have been important in the study of the island flora and fauna, the story of the rise in popularity of the islands for birdwatchers, the effect climate has had in shaping the flora and the escapes from cultivation which have now become established as part of the landscape. The sum of all these is what makes up the fabric of these unique and beautiful islands, the Isles of Scilly.

ACKNOWLEDGEMENTS

Compiling this book has taken a long time; it represents several decades of involvement with the Isles of Scilly, and it would never have been written without the help and encouragement of many people. There are too many individuals to mention everyone, but I hope that they will understand that I am hugely grateful to them all. The real generosity of those naturalists who allowed me free access to their work and who commented on sections of the text has made it possible for me to include many aspects of flora and fauna about which I know very little.

The artwork in this book has been selected from a huge volume of material I have been offered; unfortunately I could only use a small selection. Many of the photographers and artists also helped in other ways, with information and comments. For permission to use their material I would like to acknowledge Andrew Cooper, Paul Gainey, Sandra Gibson & Frank Gibson (Gibson Collection), Martin Goodey, Richard Green, Mark Groves, Alma Hathway, Ren Hathway, David Holyoak, Chris Hopkin, David Mawer, Paul Sterry, Bryan Thomas, Ian Wallace, the Isles of Scilly Museum (for Hilda Quick woodcuts) and the Cornwall Archaeological Unit and Jeanette Ratcliffe. I consulted libraries at the Cornish Studies Library, Redruth, the Natural History Museum, London, and English Nature (now Natural England), Truro.

I am very grateful to the many people in the Isles of Scilly who have helped in so many ways, although space does not allow me to mention them all. In particular I thank Martin Goodey, Anne and Mike Gurr, Ren Hathway and Jo Wrigley, Wendy Hick, Francis and Carol Hicks, Johann Hicks, Lesley and David Knight, Jim Liddon, Julie Love, Amanda Martin (IOS Museum), Cyril Nicholas, Steve and Julia Ottery (and the Museum Flower Ladies), Adrian and Mandy Pearce, Penny Rodgers.

Specific help and comments on individual chapters and topics were generously given by Jon Akeroyd, J. F. Archibald, Ian Bennallick, Sarnia Butcher, Adrian Colston, Bryan Edwards, Bob Emmett, Chris Haes, Steve Hopkin, Julia MacKenzie, Rosalind Murphy, John Ounstead, Helen Parslow, John Parslow, Mark Phillips, Peter Robinson, Katherine Sawyer, Sylva Swaby, Andrew Tompsett, Stella Turk, Steve Westcott and Will Wagstaff Keith Hyatt not only read all the first draft text but found lots of useful snippets of information as only he can; Ian Beavis freely allowed use of all his material on Aculeate Hymenoptera and other groups; Jeremy Clitherow and Alison Forrester (English Nature) gave me access to many unpublished reports and other scientific information; David Mawer (IOSWT) has been a constant source of information on all aspects of natural history in the islands. The Isles of Scilly Bird & Natural History Review published by the ISBG has also been a rich source of recent information.

I must also acknowledge the team at HarperCollins, especially Richard West, who read the first draft, Helen Brocklehurst and Julia Koppitz, and above all Hugh Brazier, for many improvements to the text.

To my son Jonathan (Martin) Parslow and daughters Annette and Helen, who shared the early visits to Scilly and still love Scilly as much as I do, I dedicate this book.
