The Discovery of the Native Flora of Britain & Ireland

David with New Atlas co-authors Chris & Trevor,
'Pearman Day' at RBG Kew, 2014

We are delighted to alert you to a new BSBI publication from David Pearman called The Discovery of the Native Flora of Britain & Ireland. The book is due out in November 2017 but BSBI members can benefit from a members-only pre-publication offer and order the book now at a reduced price.

For anybody new to British and Irish botany, David was a co-author (along with Chris Preston and Trevor Dines) of the ground-breaking New Atlas of the British & Irish Flora (2002) and also a co-author (along with Clive Stace and Chris Preston) of the Hybrid Flora of the British Isles (2015). BSBI members will also know David well as our President from 1995 to 1998, a stalwart of BSBI's Records and Research Committee, the man who set up BSBI's Science Team (formerly the Plant Unit)... In fact David's contributions to British and Irish botany are so many and so various that in 2014 BSBI held a Celebratory Pearman Day at RBG Kew to honour the man himself (which caused him great embarrassment as he is also extremely modest!)

I asked David to tell us a little about The Discovery of the Native Flora of Britain & Ireland:

LM: So David, how did the idea for this book come about?

DP: When we researched the New Atlas, one of my jobs was to try to find out when each plant alien to Britain and Ireland had first been found. That was an entirely new project, but after that I realised that the only corresponding works on the discovery of our native flora were 100 years or more ago, and could well be updated. The advent of the availability of old works on the internet has been of major assistance, especially for one living away from the major museums and libraries. 

David (centre) & Chris receive the Engler Silver
Medal from Sandy Knapp for the Hybrid Flora.
Image: L. Marsh 
LM: So you've been working on The Discovery of the Native Flora of Britain & Ireland since 2002?

DP: Yes, it has taken me nearly 14 years, and the help of dozens of friends, librarians and keepers of the major Herbaria and many others to compile this work.

LM: So, who first described our native plants? 

DP: This book attempts to answer that question, starting from almost the dawn of printing, with William Turner’s Libellus of 1538. Of course there were medieval herbals in the five centuries or more before Turner, and also there is a vast body of folk-lore, but Turner was the first to describe more than a handful and to do so in print. Thus printed sources are the cornerstone of this work, and the first date is given for each of the 1670 species or aggregates of all the indisputably natives and archaeophytes, including 40 or so species that some have argued as native in the last half-century. But this is supplemented by information from manuscripts and herbaria which enable the display of an earlier date, a date of first evidence, for just under half of that total. The names of the discoverers and the counties where each was first recorded are also given, where known.

Image: L. Marsh
LM: And how do you see people using The Discovery of the Native Flora of Britain & Ireland?

DP: Though the primary purpose of the book is to show the details of the discovery and recording of each species, it will also show the progress of discovery, leading to the somewhat surprising conclusion that most (+/- 85%) of our flora had been described by the 1720s, once the critical, non-lowland and doubtful natives have been omitted. Indeed, the main achievement of these last three centuries has been a consolidation of our knowledge.

LM: I gather the book will be 450 pages long and you've told us that it covers 1670 taxa. Is there anything else you'd like to tell us about the book before BSBI members head over to the members-only area of the website to take advantage of the pre-publication offer?

DP: The very extensive Appendices cover the key herbals and floras, the relevant journals, the important works on the history of botany, some of the national herbaria and have a major section on the botanists who actually discovered the plants.

BSBI's Threatened Plants Project: interview with Kevin Walker

Copy of the "TPP book" on Pete's desk
Image: P. Stroh
The Threatened Plants Project (TPP) was a five-year survey of the fortunes of 50 British wild flowers which the BSBI Science Team had reason to suspect might be in decline. The New Atlas of the British and Irish flora, published in 2002, showed that many had declined dramatically in distribution since the 1960s and consequently they were categorised as “threatened” in the Red Data Book for Great Britain published in 2005.

Between 2008 and 2013, more than 800 volunteers (mostly BSBI members) headed out to look for the target species at known locations (selected at random) and report back on the size and habitats of populations as well as management regimes and perceived threats. 

Once the data were received by the Science Team (which comprised BSBI Head of Science Dr Kevin Walker, BSBI Scientific Officer Dr Pete Stroh and BSBI Projects Officer Bob Ellis), they started work on processing thousands of TPP monitoring forms and analysing what it all meant. This was no mean feat, as the TPP was actually one of the most extensive sample-based surveys ever undertaken.

Kevin out recording in the field
Image: P. Stroh
Now that Threatened Plants in Britain and Ireland is about to be published, I asked lead author Kevin to tell us a little more about the project and what we have learned from it about our wild flowers.

LM: So Kevin, it must have been a monumental task processing and analysing so much data! We've all been following your progress via the BSBI Science and News pages. I bet you heaved a huge sigh of relief when you finally sent the text off to the publishers! 

KW: It was a huge task to analyse this amazing dataset and yes it was great to finally get it off to the printers but we did the easy bit really; it was the volunteers who did all the hard work, visiting thousands of populations, often in remote locations in all weathers. They deserve all the credit, because if it wasn’t for them there would be no book to publish.  

The Musk Orchid section in the "TPP book"
Image: P. Stroh 
LM: Agreed, three cheers for our amazing volunteers! But how did you decide which species to target?

KW: This was actually one of the most difficult bits of the whole project as we wanted to include species that were genuinely threatened as well as species we suspected might not be as threatened as their declines suggested, possibly because they were inconspicuous or occurred in remoter areas. We also wanted to make sure there was something for everyone to survey, from Cornwall to Shetland to County Clare. No mean feat in 50 species!

LM: And can you remind us what those 800+ recorders had to look out for, once they were out in the field? 

Kevin recording Alopecurus ovatus
Image: P. Stroh
KW: Prior to survey we randomly selected known populations for recorders to revisit – this meant that we weren’t biasing the survey to the best or most accessible sites. Recorders then visited the sites armed with a 100m or better grid ref and searched for the target noting the size and extent of the population where found as well as management, signs of regeneration, habitat (National Vegetation Community where known), associated species from within a quadrat and also any perceived threats to the plant on the site. The latter was recorded whether or not the target species was refound.

LM: So once people had recorded all that lot and sent you their forms - how did you process everything? 

KW: These data were digitised into a database.

Gentianella campestris
Image: Jeremy Roberts
LM: That sounds like another big job! Ok so what would you say are the key findings from the project?

KW: One of the main findings was the extent to which lack of management is now threatening plant species across a wide range of habitats. This is in marked contrast to the 1960s and 1970s when habitat loss was the key threat to most populations. These losses have largely been driven by changing economics of farming and in particular the decline in livestock production relative to arable and other ‘low intensity’ traditional practices such as coppicing. This has resulted in the cessation of management on many sites including nature reserves and SSSIs. Marginal lands have therefore become increasingly neglected whereas roadside verges have become less suitable for many species due to eutrophication and inappropriate cutting regimes.  

LM: Could you give us a couple of examples of that please?

KW: Field Gentian Gentianella campestris is a good example of a suite of species that have declined due to lack of management; this is a short-lived species of grasslands and heaths that doesn’t build-up a seedbank and has very limited dispersal ability. It is also a very poor competitor. It therefore disappears very quickly if grazing ceases and cannot recover even if management is restored. Heath Cudweed Gnaphalium sylvaticum has probably suffered a similar fate in the uplands.

Gnaphalium sylvaticum
Image: Mark Gurney
LM: So what - if anything - can be done about this?

KW: The absolute key is to ensure that surviving populations are managed appropriately, either through agri-environment schemes or by working directly with land owners. This will be essential for the future survival of plants confined to roadside verges for example. We also need to start to link up sites through habitat creation and management so that dispersal can occur, as well as reducing the amounts of nitrogen that are currently being deposited either from the air or agriculture. Introducing species should be seen as a last resort and only when conditions are right. And finally, we need to keep monitoring our threatened plants because without the amazing evidence collected by projects such as TPP we really have no idea of what is happening to them and why.

LM: Kevin, thank you so much for talking to us about the TPP, and of course for all the hard work that you, Bob and Pete have put into this project! We've only been able to scratch the surface in this interview so I'm sure lots of people will want to buy the TPP book once it's published next month.

An adventure in urban plant hunting: Part Two

Last month we heard from Phoebe O'Brien about the urban wild flower walk she was planning to lead in Galway on 26th August. 

Participants such as writer and "lapsed biologist" Stan Carey took to Twitter over the weekend to report on how much they enjoyed the #bsbigalwaywalk. Stan's tweet is copied below and he also shared the photo on the right:

"Exploring Galway's native flora between the canal and the river. Thanks to for a fine walk & talk. "

Image: C. Seale
I asked Phoebe to tell us a bit more about how the day went:

"The BSBI Galway Walk was my first time leading an event for BSBI, and it was also the first ever Heritage Week BSBI event. I need to thank Maria Long and Louise Marsh for their mentoring through the grant application and event management, and Eugene and Ciaran for taking the heat and splitting the participants up between us. 

"I think we ended up with more than 25 explorers, including three generations in one family. It was quite a big group on the narrow path between the canal and the River Corrib. Ciaran managed to make records of 80 plants, including some water weeds which he fished out to the delight of the children, who then had to have a go too.

"We also need to thank Carroll's pub on Dominick Street for letting us use the beer garden, where we looked through the contents of my home made vasculum which some of the children had filled with plants they had found. This gave us a chance to do some revision and briefly open the floras. 

Phoebe (standing) and the urban
wild flower hunters

"The mixture of ages, languages and abilities really made it a really interesting group. I learned much from them too.

"As a follow up I've written a five page PDF covering 20 Common Urban Plants, a selection of the plants which we saw on the day. The PDF can be downloaded here.

"I really think it was worth it to bring BSBI’s work to a wider audience and I hope that we can create more beginner events like this and work with the Heritage Council again in the future".

Phoebe also asked participant Catherine Seale to offer a few comments about the walk: 

“I had the great pleasure of taking part in the walk and was really impressed by the variety of plants that we came across. The keen eyes of the guides helped me to see things that I had never properly noticed before. Indeed, I was particularly impressed by their knowledge of the aquatic plants as this a particularly hard group to master. 

Wild flower specimens ready for identification

"Species spotted included natives such as charophytes and pondweeds, and invasives including what may be Nuttal's Water Weed". (LM: I understand that Phoebe has sent this plant to one of the BSBI expert plant referees for confirmation]. 

"Botanising in the urban environment, I have to say, revealed a rich diversity that has left me wanting to learn more!  Well done to all involved.”

Many thanks to Catherine and Stan for their feedback and for the photos, to Phoebe for leading such a successful walk and for sharing the pdf, and again, we are delighted to acknowledge funding from the Heritage Council for funding this event as part of Heritage Week 2017.

Loddon Pondweed refound in the River Thames

David Morris, County Recorder for Oxfordshire, has been in touch with some exciting news: Potamogeton nodosus (Loddon Pondweed) has been rediscovered in Oxfordshire

Loddon Pondweed
Image: F. Hunt
David told me: "This rare pondweed, otherwise known from the River Loddon, the Bristol Avon and the Dorset Stour, was thought to have gone extinct in the Thames in the 1950s and there have been no Oxfordshire records for over 75 years. It was found by Frank Hunt back in August, near Marsh Lock, just south of Henley (SU774815), growing in a part of the river sheltered from boat traffic by a footbridge. Marsh Lock is less than 1km downstream from where it was seen by J.E. Lousley in 1941 and about 5km below where the Loddon joins the Thames. Frank also tells me that there is a patch in the the Berkshire part of the river too.

This is such a distinctive species that the BSBI referee for pondweeds, Dr ChrisPreston, was quite happy to verify the record from the photograph shown on the right.

Report on the Inaugural Grassland Conservation Conference: Day 2

A couple of weeks ago, we published Ashley Lyons' report on Day One of the first ever Grassland Conservation Conference. Now she's back to tell us about the second day. Over to Ashley:

"The second day of the inaugural Grassland Conservation Conference split into two very interesting field meetings.

Bill Grayson discussing grazing
calcareous grassland at Ingleborough NNR
Image: A. Lyons 
The Upland Calcareous Grassland Workshop was organised by Edge Hill University’s Ashley Lyons and kindly hosted by Natural England at Colt Park Barn, Ingleborough. The workshop set out to discuss the impacts of management of upland calcareous grassland on a range of taxa and to enable evidence based research findings to be disseminated to conservation practitioners and policy makers.

The workshop kicked off with results from Ashley’s completed PhD project which examined the impacts of contrasting grazing management on plants, spiders and carabid beetles in upland calcareous grasslands. Ashley explained the importance of maintaining a range of management treatments (including no grazing at all) across the landscape to ensure suitable habitat is available for declining carabid beetle and rare spider species. Interestingly, Ashley’s research showed that plant species composition, richness or structural complexity doesn’t differ between areas grazed by sheep or cattle as long as the stocking intensity is the same, a result also reflected by the invertebrates studied. Even the ungrazed calcareous grasslands had similar plant species richness, though the species composition of plants and invertebrates was different from grazed areas. If you’d like to read more about the study check out Ashley’s paper. 

Colin Newlands discusses grazing: behind the

Colin Newlands, Natural England’s Senior Reserve Manager for Ingleborough, then talked about the management of the NNR and the importance of continuing research in informing management decisions. Colin also discussed the successful relationship built with Bill Grayson’s Morecambe Bay Conservation Grazing Company, a model which could surely benefit conservation elsewhere.

Bill Grayson gave an interesting overview of how his cattle are used in an organic system to graze a number of SSSIs across the North West of England, growing slowly on species rich semi-natural grasslands with the aims of helping conservation and producing quality beef from healthy animals. Bill explained that as his cattle mature at around 5 or 6 years old they are considered cull animals by the market and as such they aren’t sold as meat for the table. Rather, Bill’s beef goes to producing high quality baby food!

The group then headed out to visit a site that featured in Ashley’s research and is grazed by Bill’s cattle. The group spent time in different parts of the 90 ha field discussing how cattle have helped with the establishment of plant species such as bird’s eye primrose and frog orchid. There was also discussion on how the structure of the vegetation, along with the spiders and beetles that live amongst it, are influenced by the disturbance of cattle. There was also an opportunity to see an area that has been ungrazed for over 20 years, the lack of scrub encroachment sparked interesting conversation. The ungrazed area is separated from the cattle grazed field by a sheep net fence, the side where the cattle graze has a number of young hazel saplings growing, whilst the ungrazed side of the fence has no such regeneration, a pattern Ashley has observed in several ungrazed areas of upland calcareous grassland. This probably occurs because when left without grazing the sward becomes dominated by grasses (usually blue moor grass) and develops a thick layer of thatch that together shade out other species. Despite this competitive advantage that may hinder the establishment of some plant species, Ashley pointed out that these ungrazed areas are a vitally important part of the landscape for some very rare spider species.

The workshop concluded with a discussion on proposed management recommendations made from the results of Ashley’s research, an evidence based document that will be presented to national nature conservation organisations with the aim of highlighting the importance of considering invertebrate responses, in addition to plant responses, to management when changing management practices in upland calcareous grasslands.

Those with an interest in lowland grassland conservation joined Edge Hill University’s Elizabeth Sullivan and the Lancashire Wildlife Trust’s Wigan Project Officer Mark Champion on a visit to Wigan Flashes, a site developed on ex colliery shale and Cutacre Pasture, a reserve created five years ago and managed now with a herd of longhorn cattle.

Image: Mark Champion
Discussion at Wigan Flashes centred on the botanical diversity of the meadows which are managed by annual cutting for hay, the urban location of the meadows means grazing isn’t possible. The meadows were created twenty years ago with a layer of topsoil over the colliery shale and addition of MG5 seed mix. After being abandoned for several years after sowing, the meadows became rank grassland. Mark’s intervention with mowing over the last 18 years has increased botanical diversity and led to a community close to Rodwell’s MG5 description. Interestingly, one of the five meadows has a different plant community compared to the rest despite having the same management since their creation. Suggestions from the group around soil conditions have prompted Mark to send some soil for analysis, something that revealed similar soil conditions among the meadows 18 years ago. It will be interesting to hear the result this time around. 

The meeting even found the first eyebright every recorded in the meadows along with blackening wax cap, a further reminder that nature doesn’t always require pristine countryside to thrive.

Whilst at Cutacre Pasture, an area a little on the wet side and grazed at a low intensity by cattle, the debate was about rush pasture versus grasslands such as MG8. Whilst each has their own botanical value broader management outcomes, such as habitat for breeding birds, drove the direction of the discussions.

The group at Wigan Flashes

Mark Champion said of the conference “I have really enjoyed the discussions that have developed over the last couple of days at the Grassland Conservation Conference. The visit to Wigan Flashes and Cutacre Pasture led to some quite radical management recommendations that challenge the status quo and will be useful to management of the meadows going forward.”

Both field visits were undoubtedly very enjoyable and an excellent opportunity for academics, practitioners and farmers to discuss grassland conservation management. The visits rounded off an excellent couple of days and helped to achieve the aims of the Grassland Conservation Conference. 

If you would like more information about the Grassland Conservation Conference or would like to be involved in the next meeting (proposed for 2019) please visit or contact Ashley Lyons".

Remembering Ted Lousley

It's always a pleasure to hear from Roy Vickery, former BSBI Vice-President and the man behind the excellent Plant-Lore website. He emailed yesterday with the note below:

"The South London Botanical Institute will be hosting a small exhibition about the work of J.E. (Ted) Lousley - a former president of the London Natural History Society, the BSBI and the SLBI - on Thursday 21 September from 2.30 to 5  p.m. This is part of the Institute's contribution to the Lambeth Heritage Festival, and marks the 110th anniversary of Ted's birth. All are welcome, and although the exhibition opens at 2.20, the Institute will be open from 10 a.m. (Please note that due to cabinet restoration the herbarium is currently inaccessible)".

Thanks Roy!

Last and Least - Water-lily, that is!

Image: D. Wrench
Great to hear from BSBI member Mags Cousins about a recent trip to find Least Water-Lily Nuphar pumila at Cole Mere SSSI. 

Over to Mags:

"This lovely little lily (on right) is on the England Red List as Critically Endangered. Cole Mere, in Shropshire, is the only remaining site in England".

[LM: You can download the England Red List free of charge from this page.] 

"The next nearest populations are in Scotland, which raises the question, why is there nothing in between, could it simply be a doomed glacial relic? 

Image: D. Wrench
"Apart from its isolation, another significant risk is that it can hybridise with the Yellow Water-lily Nuphar lutea. Both lilies can be found at Cole Mere: are they hybridising already? 

"The species can be distinguished by the shape of the stigmatic disks which is wavy edged or lobed in N. pumila (on left) and smooth edged in N. lutea (below right). 

"This and other features such as leaf morphology can be intermediate in hybrids.

Image: D. Wrench
"Cole Mere is not exactly a pristine location for this rarity as it is a lowland eutrophic mere which suffers from serious algal blooms in most years. N. pumila used to occur in three parts of the mere. 

"There are now only two colonies remaining but these are thought to have expanded recently in response to tree felling on the shoreline that reduced the degree of shading. 

"Could re-establishment occur in other parts of the mere naturally through seed or rhizome fragments? Rhizomes are regularly dislodged and are washed to the shore but did not seem to be rooting again and it was not known if the plants were actually producing viable seed. The image below left shows the uprooted rhizomes, probably uprooted by Mute Swans feeding on the submerged "lettuce leaves!

Image: S. Miles
"With so many questions it was time to get some experts together to find some answers and come up with a conservation plan.

"Natural England, Royal Botanic Gardens (RBG) Kew, Richard Lansdown (Chair IUCN SSC Freshwater Plant Specialist Group), Shropshire Council (the site owners) and the Shropshire Botanical Society set about a review of the status and ecology; the seed and rhizome viability and DNA analysis of the Least Water-lily at Cole Mere.

"We were ably helped by the Colemere Sailing Club who provided transport in the way they know best and the Inner Space Dive Club (on right) who just love any excuse to get underwater, even if the botanical remit was a bit different to their usual excursions: “Please can you count the number of petioles extending from the rhizomes?”

"Great fun was had by all and some really useful findings emerged which will be reported and published in full in due course".

[LM: Mags proposes submitting the manuscript to New Journal of Botany - hurrah!]

"Even better, after lots of intensive care, some brand new seedlings emerged from seed which are being nurtured by the team at Kew and will form the basis for a collection for conservation, public display and education at Kew Gardens". 

Many thanks to Mags for telling us about the Least Water-Lily!
