BSBI News: April issue published

The latest issue of BSBI News has just been mailed out to our c3,400 members and it's an 88-page corker! But if you haven't yet joined BSBI and you're wondering what all the fuss is about, read on to find out what's in this April issue - and there's a free sampler and a full free article for you to enjoy!

The article we've selected from this issue for everyone, member and non-member alike, to enjoy is called 'Right tree, right place: using botanical heat-maps to inform tree-planting' and it's by BSBI Head of Science Kevin Walker with Becky Trippier and Clare Pinches from Natural England. Many of you will remember the uproar on social media in 2020 when several species-rich sites were due to be planted, quite inappropriately, with trees; habitats supporting orchids and threatened bog plants would have been destroyed if those plans had been implemented. 

In response to this problem, BSBI has been working in partnership with Natural England, the Woodland Trust and the Forestry Commission to develop botanical heat-maps, based on BSBI data, which can be provided, under licence, to a range of land management organisations involved in decision-making around tree-planting: so our data - those millions of botanical records collected by our wonderful BSBI  members - will help to ensure that, in future, new trees and woodlands are planted in the right place. 

Read the article in full here to find out more about the heat-maps and check out free articles from other recent issues on this page.

Some of the other delights in this latest issue of BSBI News include: plant identification aids, from buckler-ferns to elms to a new dichotomous key to native and alien roses; eight pages of news about adventives and aliens across Britain and Ireland; a report on Alpine Clubmoss, which has been refound in the North York Moors after three decades; Robert Northridge's introduction to the plants of Co. Fermanagh; and President-elect Micheline Sheehy Skeffington considering how Irish place names can be used to locate rare species.

You can find the sampler issue on this page, where you'll have the option to read it on a Screen Reader, or you can view or download it as a pdf. Non-members can also access samplers of every issue of BSBI News since April 2020, when editor John Norton took up the reins. Many thanks to John for preparing the samplers which give a real taste of what's inside each issue of our membership newsletter.

Finally, you'll notice that this new issue is number 150 - and with three issues each year, this means that BSBI News is now celebrating its 50th anniversary. An article in this latest issue called 'Now we are 50', submitted by Clive Lovatt, BSBI County Recorder for West Gloucestershire just a few days before his very sad and sudden death, celebrates this milestone and looks at how BSBI News has changed over the years. It is full of delicious 'Clive-isms' - the red colour used for the title in early issues is described as 'rather arterial'; the stylised bluebell logo is "planted" on the front cover... Clive will be much missed for his way with words, as well as his botanical skills. 

Everyone, whether member or non-member, can enjoy reading electronic back issues of BSBI News, from No. 1 (published in 1972) to No. 136 (September 2017), on our BSBI News archive page. This latest issue and other recent issues are available, to BSBI members only, on the recently revamped password-protected members' area of the BSBI website. Print copies of BSBI News are also posted to any members who prefer that option (a growing number are opting for paperless membership).  

If you are keen on wild plants and you enjoy the samplers and the free articles, do consider joining BSBI: access to the three full issues of BSBI News each year is just one of the many benefits you will enjoy as a member - find out more here.

Alpines and a plant for Easter: April report from BSBI President Lynne Farrell

Last month saw BSBI President Lynne Farrell looking for signs of Spring up in Cumbria, where she is based. 

So, has it warmed up yet? 

Over to Lynne:

"It has been very cold and windy up here recently so I am focusing on plants photographed in the shelter of the garden and at the local Alpine Garden Society Spring show, which displayed plants of different colour, shape and form. 

"I know these are not native British species, but it might give you ideas on how to grow alpines in various pots. Most people will be able to find a brick and so could create their own miniature garden, and these examples (on the right and at the foot of the page) show you what can be achieved when you become more adept at construction and putting the right plant in the right pot.

"As it is Eastertime, I’ve also included a Pasque Flower, Pulsatilla rubra, from my garden (on left). In the next few weeks our native P. vulgaris will be in full bloom on the chalk in SE England or oolite in Gloucestershire, with one site on magnesian limestone in the north. 

"Take a look at this BSBI distribution map which shows where the plant has been recorded by our volunteer members over the years.

"One of the best places to see P. vulgaris is at Therfield Heath/Castle Hill on the Cambs/Herts border, where you can walk along the Icknield Way before heading up the steep slope to see the purple flowerheads and finely divided, silky-hairy leaves. 

"Its stronghold is in France, but I’ve never been early enough to see it in bloom there.

"A detailed account of this and other grassland species features in Grassland plants of the British and Irish lowlands (BSBI 2019) co-authored by the BSBI Science Team Kevin Walker and Pete Stroh, together with several BSBI members who have studied grasslands for many years. This book is well-illustrated and recommended. 

"There are alpine Pulsatilla species too, which can be seen growing in species-rich meadows on the continent".

Signs of Spring: March report from BSBI President Lynne Farrell

Narcissus at Sizergh Castle NT
Image: L. Farrell
Last time we heard from BSBI President Lynne Farrell, she was looking at mistletoe but as we move towards Spring, what is Lynne looking out for now? 

Read on to find out: 

"During the past few weeks plants and animals have begun to stir as the days lengthen a little, and I now have three clumps of frogspawn in my garden pond. Most of the local colour is from Spring bulbs, some of which are native in parts of Britain and Ireland and others which are neophytes throughout this range.

Narcissus pseudonarcissus (daffodil) is considered to be native in England and Wales and an alien in Ireland and Scotland, while Leucojum vernum (Spring Snowflake) is a neophyte, being introduced into gardens from where it has spread into the wild with the first wild record being in 1866. Two sites in SW England were thought to be native.

Sizergh Castle NT

Daffodils, of which we have several species and hybrids, are essentially all neophytes (apart from N. pseudonarcissus much beloved by Wordsworth), including the Tenby Daffodil, N. obvallaris introduced and now naturalised in South Wales. It was St David’s Day on 1st March so were they in bloom then? 

Daffodils are also collectors' items, rather like Snowdrops, but I do not know the equivalent name for Galanthophlies. Perhaps someone can inform me?

Spring tidying up (image below) is also in progress after the various storms we have experienced. Fallen trees are being felled, cut up and transported locally for firewood, but many are being left in place in coppices and more inaccessible places to provide wild life habitats in the future.

Several large trees blown down near where I live by storm Arwen, crashed in to the walled garden and damaged several old fruit trees. Work continues to ‘tidy them up’, so that safe access can be gained to the allotments. This will take some time throughout the country and no doubt the recovery will be compared to the Great Storm of 1987.

British & Irish Botany: issue 4.1 published

The latest issue of British & Irish Botany, BSBI's open access, online scientific journal has just been published and there is a distinct watery theme.

National aquatics expert Richard Lansdown, author of BSBI Handbook #11 on Water-starworts, has collaborated with colleagues to produce a paper on two duckweeds new to Britain. Wolffia columbiana was found last year in ditches in the Pevensey Levels in Sussex and later in grazing marsh complexes in Somerset, Kent and on the Gwent Levels, where Wolffia globosa was also discovered. The genus Wolffia famously includes the world's smallest flowering plant so it's perhaps not surprising that these duckweeds aren't the easiest plants to spot.

the taxonomic history of some members of
this group of sea-lavenders.

We head to the Welsh and Scottish coasts for the next two papers: firstly, Ivor Rees describes a new and distinct subspecies within the Rock Sea-lavender Limonium binervosum aggregate from an Anglesey saltmarsh. This taxon has been known since 2006 but has only now received formal taxonomic recognition. Staying by the coast, Mike Wilcox considers Sea Couch and coastal hybrid couch grasses in Scotland. 

Mike moves inland for his second paper in this issue as he looks at Scentless Mayweed. Mike is well known to News & Views readers because he often reaches out to botanists across Britain and Ireland to ask them to send him plant specimens for closer analysis. If you are one of the many botanists who have responded to Mike's requests, then thank you for your contribution to scientific papers such as the ones in this issue. Please keep up the good work and keep an eye out the next time Mike asks for specimens!

We also have a paper for the many orchid fans who read British & Irish Botany. David Trudgill has been mining the BSBI Distribution Database to do some analysis on twenty species of orchid recorded in Scotland in recent decades, to answer the question 'are they declining and if so, to what extent'? It turns out the situation isn't as clear-cut as you might have thought... BSBI members can also enjoy a similar paper by David in the latest issue of BSBI News, our membership newsletter. If you aren't already a member, do consider joining us and you'll have online access to every paper ever published in BSBI News, from issue 1 in 1972 right through to the January 2022 issue which contains that paper by David on records of orchids across Britain and Ireland.

For grass aficianados, we also have a paper by Clive Stace on subspecies of Vulpia geniculata. If you are looking at these six papers in this latest issue of British & Irish Botany and thinking, hmm I have some similar observations about a plant in my area, please do consider submitting a draft or just email us for a chat. Editor-in-Chief Ian Denholm and I can soon tell you if it's worth writing your finds up for the journal, or if it would be better to run your draft past John Norton, editor of BSBI News, or there's always the option to publish on this blog. If you have something interesting to say about British and Irish plants, the chances are that your fellow botanists will want to hear about it - it's just a question of choosing the most appropriate place to publish. Don't be shy, drop us a line! And meanwhile, please enjoy the latest issue of British & Irish Botany.

Interview with Mark Lynes, author of BSBI Handbook #24: Alchemilla

There’s a new addition to the series of BSBI Handbooks: we are delighted to announce that Alchemilla: Lady’s-mantles of Britain and Ireland is due to be published in April. BSBI members will be able to benefit from an exclusive introductory offer of £12.50 (excl. P&P) which will save them £7.50 compared the RRP of £20.

I spoke to Mark Lynes, the author of the new Handbook, to find out what made him decide to devote years of his life to the study of Lady’s-mantles. Mark also provided all the images which illustrate this interview.

LM: Mark, before we start talking about the new Handbook, could you tell us a bit more about yourself please, and how you got started as a botanist?

ML: Well, I’m a Chartered Legal Executive by profession, practising as a conveyancing lawyer, for many years based in Doncaster, more recently in Lincoln. I’ve been interested in natural history for as long as I can remember. Whilst still at school, Brian Eversham (now CEO of the Wildlife Trust for Beds., Cambs. & Northants.) and I carried out a detailed botanical survey of a local peat moor, which is still talked about to this day. I was even a member of BSBI back in the day. Subsequently I was ‘lost’ to birding for around two decades, twitching in particular – charging up and down the country chasing rare birds. It was not until the early 2000’s that I finally came to my senses and took up serious botany once more.

Alchemilla glaucescens

LM: Well I’m glad you saw the light and came back to botany, Mark! But then what drew you to Lady’s-mantles as a genus? Many of us – especially if we are gardeners – will have an idea of what a Lady’s-mantle looks like but may not realise that there are many different species.

ML: Well, the obvious thing for a lapsed (bird) twitcher, is to immediately dive into rare plant twitching! Soon enough I came upon Alchemilla. Seeing that there were only 12 native taxa, I thought ‘well, how hard can it be?’ and was soon up in Teesdale, where I quickly discovered ‘very hard indeed’. This would have been around 2005 and I came home from my day out with a multitude of specimens and photographs, absolutely none of which I could identify. This seemed like a challenge and – as I am nothing if not obstinate – I immediately set about teaching myself to speak Alchemilla.

mode with binoculars
LM: Oh dear, I’m afraid I laughed out loud at that ‘how hard can it be’! We’ve all done it though, started on a new group of plants and then realised the enormity of the challenge ahead – especially challenging if there isn’t a BSBI Handbook to help us along the way. So, what exactly made you decide to take the leap from being an Alchemillaphile to taking on the mantle (see what I did there?) of being a Handbook author? Did you put yourself forward or were you press-ganged by BSBI staffers?

ML: By 2012 I had somehow come to the attention of Kevin Walker, BSBI’s Head of Science, and a meeting was suggested. We met at Doncaster railway station in early 2012, where Kevin was on a brief stopover, changing trains en route back from a school reunion do of some sort. Here, I’m afraid to say my ego rather got the better of me and when Kevin suggested I might like to ‘do the handbook’, I jumped at the chance. The fact he also dangled the prospect of a small financial grant which would enable me to go to Scandinavia to study Alchemilla was a ‘Brucie bonus’ (younger readers might need to Google that saying).

Alchemilla wichurae - close-up of the flowers

LM: Er, you had ‘somehow come to the attention of…’? Our Head of Science is not easily impressed so you must have built up quite a reputation by that point! So, tell me a bit more about the Handbook – I know that it’s around 220 pages long, and covers 20 taxa. How many are native and how many alien?

ML: Yes, the Handbook covers 20 taxa in detail – 15 native and five alien – four of which I recently described. An appendix includes details of a further nine taxa which either might conceivably be found in Britain and/ or Ireland or are otherwise relevant in some way.

LM: And descriptions of those four new taxa were published in British & Irish Botany, BSBI’s in-house scientific journal. The first, Alchemilla sciura, is here, published in 2019, and the other three species, all from northern Britain, are here, published in 2021. When did you start working on the book?

Alchemilla glabra

ML: The work really started with the BSBI-funded visit to Sweden and Norway in June/July 2012, so – and as I say in the book – it has been a long time in gestation. The actual writing process began on the 2nd of January 2016 and for this and the following two winters, I barely left the house. Pressure of work and the desire to remain married meant I could only realistically work at weekends. Summers were taken up with fieldwork, collecting and photographing Alchemilla from across Britain and Scandinavia.

LM: Could you give us an example please of one of the species you cover and what we can expect to find out from the new Handbook about its identification, distribution and current conservation status?

Creag na caillich

ML: Each of the 20 species covered in detail is lavishly illustrated with numerous colour photographs illustrating all of the key features, including leaf teeth and hypanthia, for example. Many species have additional plates devoted to images of individual leaves, illustrating both the variation within the species concerned and identification criteria. Each species account begins with details of the ecology, distribution and conservation status of the species account, most of which were prepared by Kevin Walker. For some species – for example A. sciura – I have been able to update what we know of the distribution of the plant, based on fieldwork conducted as recently as summer 2021. The identification of each species is covered in great detail also, yet is written in a relaxed, and so hopefully accessible, style

LM: You must have visited a lot of locations across Britain and Ireland in the course of your research. Are there any that particularly stand out in your memory?

Alchemilla neomanifesta
ML: Well I absolutely love Grass Wood in the Yorkshire Dales. I’m not normally a ‘woody’ person, but there’s just something about the place that makes it very special. I suppose the fact it holds five native species of Alchemilla, including the recently described A. falsadenta, helps. If only there weren’t so many ticks there now. In Scotland, I have a thing about Creag na Caillich in Ben Lawers NNR. It’s somewhere I can imagine finding just about anything Alchemilla-wise – and of course is home to another of my recently described species A. neomanifesta. A visit in the company of Sarah Watts, then of NTS Scotland, will live long in the memory, not least for the fact that we broke a tyre on the NTS 4x4 on the way back to the road. So, if ever you need a tyre changing on a Toyota Hilux, I’m yer man!

Herbarium sheet of A. glabra
collected by Margaret Bradshaw

LM: Thanks Mark, I’ll let you know if I’m ever in that situation! But as well as field visits, did you visit many herbaria to look at specimens? Are herbarium specimens particularly useful when it comes to Alchemilla identification?

ML: Herbarium specimens are extremely useful in the identification of Alchemilla and the book would have been impossible without access to them. Things which are not apparent in the field, tend to reveal themselves when subjected to a 10x hand lens or similarly low-powered microscope. That said, I physically visited only two herbaria, the one at Cambridge University and one in Umeå University, Sweden. However, I did spend three days solid in the latter, working until midnight on occasion, before going out collecting Alchemilla the same night. For the majority of my specimen research, I relied on material I collected, or which was sent to me by various BSBI members and County Recorders, together with gifts of specimens and some use of herbarium loans.

Specimen of A. glomerulans
sent to Mark for determination 

LM: Sounds as though you got a lot of feedback from BSBI County Recorders, our expert referees and many of our “ordinary members” who go out plant recording. Is there anyone in particular whose help you would like to acknowledge?

ML: Over the years I have received innumerable specimens sent to me my BSBI members and County Recorders from across Britain and Ireland, such that they are far too numerous to mention individually. One who does particularly stand out, however, is Paul Smith, the County Recorder for the Outer Hebrides (VC110). I receive a package from Paul most years and always look forward to it as I am seeing material from far-flung locations I have never visited, and in many cases probably never will. One constant throughout work on the Handbook has of course been my fellow Alchemilla referee, Dr Margaret Bradshaw. In the early days – before work on the book commenced or was even mooted - I attended a couple of her Alchemilla workshops held in Teesdale. Until encountering Margaret, I was essentially self-taught in the ways of Alchemilla. Her knowledge of the Alchemilla species of these islands is unrivalled and I have tapped into it on every available opportunity. She’s always been very generous with her knowledge and, more recently with literature and specimens, some going back to the 1940’s. Within the last couple of weeks, I went up to see her at her home in Teesdale and came home with boxes – literally – full of papers and documents. My visit also gave me an excuse to go and see the Red-flanked Bluetail which is wintering along the river near Wynch Bridge (Kevin Walker will be impressed, even if nobody else is…)

Margaret Bradshaw's stomping ground
 in Teesdale

LM: Hmm once a twitcher, always a twitcher…. But back to the plants! Tell me about the illustrations: they are always an important part of any BSBI Handbook – so, what can we expect here – photographs? Drawings? Diagrams? And are there distribution maps?

ML: Photographs, yes. Lots and lots of photographs, over 200 in all, showing just about every conceivably useful identification feature, or simply being very nice to look at. Whilst photos do much of the heavy lifting, they are ably supported by ‘hair diagrams’ for each species, these illustrating typical maxima and minima hair distribution on the leaves and stem/inflorescence of each species

Mark's Alchemilla collection
LM: Finally: all BSBI Handbook authors benefit from an editor to help them through the process towards publication. Who was your editor?

ML: There are two things which have – finally – made the book happen. The first is my taking early retirement from work, thus finally freeing up the time required to put the thing together. The second and equally important factor, has been my editor, Jeremy Roberts. I’ve known Jeremy for a number of years now and, for me, he was a natural choice as editor. What I did not fully appreciate when I asked him, was just how pivotal he would be to the whole process. Not only has he wrangled my text into something readable, he is also responsible for the aforementioned hair diagrams, together with all the other drawings and diagrams within the book. Without Jeremy’s input, the book would not have been anywhere near as good as it hopefully is. I owe him a huge vote of thanks.

A. glomerulans

LM: Well said, three cheers for Jeremy! Thanks for talking to us about the new Handbook Mark, the 24th in BSBI’s series of Handbooks for difficult plant groups. Alchemilla: Lady’s-mantles of Britain and Ireland has been a long time coming but it looks as though it will be well worth the wait – many thanks to you and Jeremy for all your hard work and thank you for talking to me today. Before you go, may I issue an invitation to you please? Might you think of leading an Alchemilla workshop at some point, so we can all road-test the new Handbook?

ML:  Yes, I am hoping to organise an Alchemilla workshop at some point once the book is out of the way, although it may be next year now, so watch this space!

A. filicaulis var. vestita 

LM: Thanks Mark! Now, readers will want to know how to get hold of a copy of the new Handbook.

If you are a BSBI member, there is a flyer tucked inside the January issue of BSBI News which you should have received by now.

Mistletoe searches and a bright spark: February report from BSBI President Lynne Farrell

Mistletoe in Arnside
Image: L. Farrell
Last month BSBI President Lynne Farrell told us about her New Year Plant Hunt and was looking forward to reading the analysis of this year's results - she won't have much longer to wait because the report is almost ready for publication

So, what has Lynne been up to in the meantime? Over to her for her February report:

"It has been dull and overcast here in Cumbria, with the occasional ray of sunshine breaking through and strong winds re-occurring, so still unsettled conditions in many ways.

"At this time of year I feel restless and want to get out recording and searching for plants to brighten up my day. So having previously conducted surveys of Mistletoe Viscum album when living in Cambs., I’ve now turned my attention to Cumbs. There are very few recent records for the latter but the starting point was gathering information from the Flora of Cumbria and the BSBI Distribution Database, then contacting  local botanists. 

Mistletoe in Heversham
Image: L. Farrell

"The past month has seen me patrolling nearby villages, especially around Heversham, near Kendal, with my binoculars, camera, notebook and GPS. Quite a few people came out when they saw me wandering around and peering through my binoculars asking ‘Can we help you? The answer was ‘Yes, of course’. So now I have a distribution map of Mistletoe in the village and also a selection of locals ready to spot further plants. Mistletoe is an iconic species and one which attracts attention and interest.

"This is a particularly good time to search for it before the leaves appear on the trees. It is remarkable how difficult it is to see later on as it becomes hidden in the mass of greens. Jonathan Briggs has recently updated his previous work on Mistletoe and his paper can be found in the latest issue of British and Irish Botany

Winter Aconites
Image: L. Farrell
"Up here I have found it in old Apple orchards, in gardens on Crab apple and apple, on Limes in the churchyard and nearby Levens Hall, and on Hawthorn in old hedgerows, with just one sighting on a Silver Birch. I counted female and male spheres and also noted that they were many small plants, which indicates a healthy population. Locals also informed that it is spreading in Heversham.

"Although the orchards may be disappearing from some parts, they still exist in this area. The results of my survey have been sent to the BSBI County Recorder and he has now asked Cumbrian botanists to go out and search for it their areas. Perhaps you can also contribute where you live?

"One bright, welcome sight was a clump of Winter Aconite Eranthis hyemalis on a roadside bank. It's a neophyte, introduced into gardens around 1596, and first recorded in the wild in 1838. It is certainly amongst the first plants to flower in the year."

Changing times: January report from BSBI President Lynne Farrell

Happy New Year to you all and I hope that you were able to participate in the New Year Plant Hunt, which ran from 1st to 4th January this year, and is becoming increasingly popular. I am actually thinking that it might be good to do Spring, Summer and Autumn Hunts in the same monad (1km x 1km grid square) so that I can compare the phenology throughout these changing times. 

Although we have seen increased numbers of taxa in flower at New Year for the past two seasons, this year there has been a decrease, at least up here in Cumbria. Storm Arwen, cold and wet conditions in November and December are probably the causes of this, but we will wait for the overall analysis to come out later this month and then we can compare with analyses from previous years.

As an example, last year we recorded 43 species around Arnside but only 16 this year. The normally productive sea front had been well and truly blasted by Arwen, except for Spartina which withstood the winds, and - although it is a fungus and so I did not add to the list of plants - the poisonous Ergot was evident on the grass. However, we did find a few species in sheltered spots including the sweetly-scented Winter Heliotrope Petasites fragrans (image above right). Goldfinches sought refuge in my garden and were feeding on the seed heads, which I had left deliberately for them (image below left). 

There have been many changes and challenges in the past year and, of course, things will continue to change, so we will continue to learn and evolve. Opportunities will be presented and let us try to accept them and move forward again. Sometimes it feels like we are in the ‘murk’ but there is always the chance to emerge from this into the clearer light. 

Recently many of you will have experienced the weather inversions, which provided spectacular views of ‘floating hillsides’ across many parts of Britain and Ireland. Here are a couple of images (below) from Arnside Knott from where you can usually see the sea, but in late December it was totally covered in mist and only the higher ground could be seen rising above.
