For botanists who will be in Ireland on 22nd September, the BSBI Ireland Autumn Meeting 2018 (including Irish AGM) is taking place at the National Botanic Gardens, Glasnevin, Dublin. Irish Officer Maria Long tells me that "the plan for the day includes a talk by Úna FitzPatrick on the pilot ‘Rare plant monitoring scheme’ run by the National Biodiversity Data Centre, a report back on the Charophyte Workshops run earlier this year, a session by Paul Green entitled ‘Atriplex around the Irish coast’, and lots more". 

The event is aimed at everyone who wants to know more about wild flowers in Ireland, regardless of whether they're a botanical expert or a BSBI member. It runs from 10am to 5pm, it's free and booking is not required, so head over to the new Irish Autumn Meeting webpage to find out more.

For botanists who will be in Britain between 12th and 14th October, the 2018 BSBI Recorders' Conference is taking place at FSC Preston Montford. This event is residential (so not free, sorry!) and it's aimed at active recorders (whether advanced botanists or just starting out with recording). 

There’s a selection of 13 different workshops or drop-in sessions to choose from on subjects such as recording docks, brambles, oraches and firs, and there are sessions on dandelion and grass ID for beginners; there are 11 talks, ranging from Tim Rich & Andy McVeigh on new Gentianaceae taxa to Geoffrey Hall on ‘citizen science and the recorder’ to Pete Stroh on 'Atlas 2020: the final countdown'. 

There’s a field trip on the final day with John Poland to road-test his new Twig Key, and of course there will be Summerfield Books’ pop-up shop to browse and lots of networking opportunities. To find out more and to book your space, head to the Recorders Conference page. 

We like to think that we offer botanists a range of indoor and outdoor meetings to suit all tastes, wherever you live across Britain and Ireland. But if you're sitting at home thinking "Why oh why do they never have meetings in my area to help me ID my favourite group of plants" - email us and we'll see what we can do! BSBI's Meetings & Communications Committee meets next month to plan next year's programme so we're keen to hear your suggestions.  

Flora of Great Britain and Ireland: special offer for BSBI members

We were delighted to receive this note from Philip Oswald:

"The last of the five volumes of Peter Sell’s and his long-term colleague Gina Murrell’s Flora of Great Britain and Ireland was published by Cambridge University Press on 12 April this year, the culmination of over 30 years of dedicated labour based on the Cambridge University Herbarium (CGE), where Peter was employed from 1944 till 1997 and continued to work after his retirement; when he died in 2013 a small team of his friends undertook to see the last two volumes through the press.

"This definitive Flora provides detailed accounts of the native species, naturalised species, frequent garden escapes and casuals found in Britain and Ireland, including some newly described ones. 

Gina Murrell delivers her address at this year's
event celebrating the publication of the
final volume of Sell & Murrell's Flora.

"Full keys and descriptions enable the user to name all plants occurring in the wild and some ornamental trees and shrubs. For the first time, accounts of all the large apomictic genera are included. 

"Each species entry begins with the accepted Latin name, synonyms and English name. A detailed description follows, with the flowering period and chromosome number. Separate descriptions are provided for infraspecific taxa and many hybrids. 

"The status, ecology and distribution (including worldwide distribution) of the taxa are also given.

Scots Pine: in history and in Byron's Gin

taxon=pinus_sylvestris,1

Ancient pollen deposits suggest that Scots Pine is native to north-west Scotland (north of the Highland Boundary Fault) and forests of this beautiful tree once covered much of the Highlands.

Flora Celtica tells us that "the deteriorating climate, from the Mesolithic era onwards, did much to favour the development of bogs at the expense of pine forests from around 9000BC". The next impact on the forests occurred from the C17th onwards, as human populations increased and pines were increasingly felled for timber and transported southwards. Huge numbers of logs could be floated down rivers such as the Dee and the Spey when they were in winter spate. Once the timber reached the Central Belt, it was used to make cladding for houses, for furniture and for naval uses (oars, masts, spars and bowsprits).

Other parts of the pine trees were also used: split roots were used as tapers (candles) in poorer homes and to make creels (for lobsters, or for carrying seaweed up from the beach to spread on the fields).

Resin from the bark was also used as a medicine, mixed with beeswax and hog's lard to make poultices for sores. Pine oil is still used as an antiseptic today, for example in aromatherapy.

Today, native pinewoods cover only around 17,000 hectares in Scotland - this is believed to be only around 1% of the area originally covered. The tree is however widely planted in areas outwith its native range, and now extends from southern Spain northwards to Scandinavia, and from Scotland eastwards to Siberia. This BSBI distribution map shows where our members have recorded Scots Pine across Britain and Ireland.

Scots Pine has also been used since the 18th century to flavour beers and now small amounts of it are used in the award-winning Byron's Gin: Melancholy Thistle, along with other botanicals, such as Sweet vernal-grass, Rowan, Aspen, Downy Birch and Juniper, which grow in the grounds of Speyside Distillery and environs. 

If you want to identify Scots Pine when you are out walking: all pines have needle-like leaves grouped together in clusters of 2, 3 or 5. On Scots pine there are just 2 leaves in a cluster and they don't exceed 10cm (longer than that and you probably have Corsican Pine rather than Scots Pine). The bark on Scots Pine can also have a distinctive pinkish tinge to it which should help you identify it. 

And once you get home from your walk, you can enjoy a glass of Byron's Gin happy in the knowledge that for every bottle sold, a contribution is made by Speyside Distillery towards BSBI's training programme so that we can help more people learn to identify wild flowers, including aquatics, grasses and Scottish orchids, ferns and trees. 

Oxfordshire's Threatened Plants

Today's guest blogpost is by David Morris, the County Recorder for Oxfordshire, about a rather important book launch he attended last month. 

Over to David:

"This summer saw the publication of over ten years work on the Rare Plant Register for Oxfordshire, adding one more to the ever increasing collection of these invaluable documents. 

"Published by Pisces Press, Oxfordshire’s Threatened Plants departs from some other county Rare Plant Registers in covering the modern administrative county, i.e. the vice county of Oxfordshire (VC 23), the Vale of White Horse (known locally as Occupied Berkshire, VC 22) and tiny areas of some other neighbouring vice counties.

several fens in the county

"The book charts the fortunes of 274 studied species, around a third of the county’s natives. 

"Based on records of nationally or locally rare and scarce species gathered up to around 2012 when field work for the project ended, the book describes the ravages of the twentieth century on our indigenous flora. 

"While a small number of species studied are not doing so badly as first thought, most have fared rather less well, with more than fifty considered to have become extinct, around ten per decade between the 1970s and ‘90s.

"Oxfordshire’s Threatened Plants goes beyond a mere list of plants, however, providing some ecological analysis of the carnage.

flora of Oxon's waterways, hanging
on at places such as Otmoor

"Unsurprisingly, the losses are concentrated among stress-tolerating species, such as many arable plants and those of low-nutrient habitats such as fens. 

"Many also demand suitable grazing or other management, which it is increasingly difficult to provide except by dedicated volunteer work. These trends are lucidly described and illustrated in the book.

"All is not gloomy, however. Fortunately, a small number of the plants listed in the book as having lost out in modernity’s race to the bottom have been rediscovered in Oxon recently. 

"These brilliant records, such as Potamogeton nodosus (Loddon pondweed), are described on my blog with much fanfare. 

"The book also highlights the critical work of the Oxfordshire Flora Group and Wychwood Flora Group in staving off extinction of our most important and threatened plants, several of which grow almost nowhere else in these islands.

"As a final thought, if the efforts of Oxon’s plant conservationists come to nothing and in fifty years the situation in the county is even more dire, then at least there is now a colourful and boldly worded document out there in the public domain to say ‘we told you so and tried to do something about it’. 

"Please buy a copy and support this work".

Many thanks to David for telling us about this new publication and about the threatened plants in his county. See also Threatened Plants in Britain and Ireland by Kevin Walker, Pete Stroh and Bob Ellis, published late last year and recently reprinted due to popular demand.

BSBI Mayo Recording Event 2018: Day 4

On the final day of this year's BSBI Mayo Recording Event I was fortunate to be in Robert Northridge's team. Robert is a bit of a legend - a superb botanist, Chair of BSBI's Committee for Ireland, County Recorder for Fermanagh and Co Cavan; Robert also picked up an MBE last year for his years of voluntary work, including  bringing communities together in the aftermath of the Eniskillen tragedy.

The previous day, Robert's team had refound the rare and beautiful Irish lady's-tresses Spiranthes romanzoffiana in the same site where they had discovered it several decades earlier, and they were telling us all about it over dinner. 

They soon realised by our 'oohs and 'aahs' that this was a plant which I and Russell Parry, one of the County Recorders from VC55 who had travelled over with me, had never seen. But the next morning, Robert and his wife Hannah picked me and Russell up ready for our day's recording and told us "First, we have a little treat planned for you..."

Parnassia palustris

You guessed it - they took a detour and drove us up to see the Irish lady's-tresses! The lake shore where the orchids grew also had more Parnassia palustris than I've ever seen in my life, along with just about every other wet meadow species you can think of! 

Little treat? It was one of the nicest places I've ever visited! Apologies that my pathetic phone photos don't do it justice. 

It was hard to tear ourselves away but there was recording to be done and we were keen to help where we could and learn from the master. Over the course of the day we visited a range of habitats in the hectad M29 to try and notch up as may species as possible.

We tramped over bits of bog, squinted from bridges into the water below, and peered into hedges, road verges and even a cemetery in pursuit of  more species that we could tick off  on our recording card. 

Towards the end of the day and all (apart from the indefatigable Robert) starting to droop a bit, an unusual pondweed was spotted in the River Moy. 

Robert thinks it might be Potamogeton x lanceolatus, a hybrid known only from the west of Ireland. He has pressed the specimen and sent it off to the BSBI's expert referee for pondweeds - exciting!

We recorded more than 220 taxa in M29 over the course of the day, bringing the all-time total to over 300. A fitting end to a wonderful recording event organised by the excellent Maria Long. 

Perhaps the best thing about the event was the mixture of attendees: young and old, male and female, from experts like Robert to beginner botanists who had never attended a BSBI event before. Check out this blogpost by "amateur botanist" Karina, who was out plant-hunting on Day 4 along the shores of Lough Carra with Rory, Mark and Maria; she says she had a "great day out" and "learnt so much". Karina took some great photos for her blogpost too! 

We all had a wonderful time and collected lots of records which will feed into Atlas 2020. And at the risk of sounding unbearably smug: some of us were also lucky enough to see Irish lady's-tresses!

Day 2: On our second day on Clare Island we split into three groups again.

I was in a group led by Rory Hodd, legendary leader of Ireland's Rough Crew. We visited the only bit of woodland on the island where we spotted plants typical of ancient woodland, such as Sanicula europaea and Oxalis acetosella. After yesterday's coastal heath I felt I was back on home territory, being based in the English midlands! 

To kick off the woodland visit we had a short talk by landowner Ciara about which species she had planted and which were there already. Mark, who is volunteering on Ciara's farm this summer, and part-time resident/local historian Malachi, both joined us for the day and we benefited greatly from their local knowledge and enthusiasm.

After a few hours we emerged from the woodland into some bog with a fabulous view across the bay to a range of mountains and I knew I was definitely in the west of Ireland and not in Leicestershire! 

Rory was on superb form identifying spike-rushes without even bending down because he knows the plants and the habitat so well. He also managed to spot charophytes and Utricularia spp. in a bog pond (I would have trotted past and not even noticed them!) and took specimens of both to look at more closely later on.

After lunch we headed down to the saltmarsh and spotted Aster tripolium, Bolboschoenus maritimus, Tripleurospermum maritimum and lots of things I never see in Leicestershire. 

A purple patch: Pinguicula vulgaris

After a great day's botanising we just had time for an ice-cream and then we headed for the ferry back to the mainland. Most of us set off on the drive to Castlebar, our base for the next few days, while Rory and botanists Roisin and Kate Marie sailed off to Inishturk for a day's recording before rejoining us.

Day 3: Today on the mainland I joined a group led by Eamonn Delaney who recently took on the mantle of County Recorder for East Mayo. We managed to cover five monads to the southeast of Knock and notched up 227 taxa in all. Highlights of the day were Sparganium natans, Parnassia palustris, a gorgeous patch of Pinguicula vulgaris in flower, another mystery Utricularia, Galium uliginosum which we don't see much of in VC55... actually the whole day was one great big highlight!

Another group led by Maria Long were recording a little to the north of  Eamonn's group. Their first monad was so rich, with 115 taxa within 100m of the car! They moved on to a boggy area after lunch and found six carnivorous plants within a few meters of each other: both Drosera species and the hybrid between them; 2 Pinguicula spp. and a Utricularia!

We caught up with the third group for dinner. Leader Robert Northridge had led his team to a coastal square with a river flowing through. They recorded 183 taxa in their first monad, including three Droseras, both Triglochins, Hypericum humifussum, Lythrum portula, Utricularia minor and Radiola linoides. On the way back, they visited a stony lake shore which Robert and his wife Hannah had visited decades earlier and found Parnassia palustris and Spiranthes romanzoffiana. Would they refind the Spiranthes? Yes: botanist Fiona was in Robert's group and spotted several spikes.

2018 BSBI Mayo Recording Event

Rory, Roisin and Kate Maria also joined us at dinner, fresh off the ferry from Inishturk. I asked Rory how he got on and he explained that he'd been out on Inishturk earlier this year so was really just going back to add a few more species. He's a modest chap so Maria, sitting next to him at dinner, explained this actually meant that 100+ species were added and Rory had found Euphorbia hyberna, a new record for the whole of Mayo, before 9am.   

So, another fabulous day with the delightful and incredibly modest Irish botanists!

Tomorrow is our last full day of recording. It will be hard to top the three amazing days we've already enjoyed - catch up with us here to find out how we got on. To find out more about the 2018 BSBI Mayo recording Event, check out this #BSBIMayo2018 hashtag.

BSBI Mayo Recording Event 2018

Botany on the edge:
don't jump Eamon!
Image: M. Long

Today was the first day of the 2018 BSBI Mayo Recording Event and I was privileged to spend time in the field with one of the three recording groups. 

Our group, led by BSBI Irish Officer Maria Long, headed to the north of Clare Island to record as many species as we could for Atlas 2020. We covered four monads and collected a grand total of 321 records. Ok, some were duplicated from one monad to another, but we still felt very pleased with ourselves by the end of the day! Beginner botanist Kate was in our group and I asked her what her "plant of the day" was. She chose Triglochin palustris (Marsh arrowgrass) with its delicious scent - a mixture of coriander and carrots! 

Rory and the Rough Crew

While we were out recording, we ran into media celebrity Duncan Stewart who presents and produces the very popular Irish TV programme Eco Eye. Duncan said it was wonderful to see Maria Long again (they are old pals) and good to see us looking at native plant species (I tried to tell him about our Atlas recording but he already knew all about it!). Duncan also asked "What about the invasive species?" - we had a good chat about Gunnera tinctoria which is being spotted increasingly frequently and Duncan has some very interesting ideas on control - and "What about climate change?". Duncan is hoping to cover these important issues on forthcoming programmes, so we'll keep you all posted about this. 

Salix herbacea

We caught up with the other two groups in the evening to compare notes over dinner and a drink. BSBI national field meetings like this are social occasions as well as recording events, so we really like to enjoy ourselves after a day in the field!

Robert Northridge's group had covered three monads and made more than 300 records in the west of the island. I asked Robert what their "plant of the day" was and he couldn't decide between Empetrum nigrum, typical of the boggy/ acid grasslands found here, and Crithmum maritimum, spotted at the end of the day on a south-facing cliff. 

Rory Hodd took a Rough Crew group up to the top of Knockmore, the highest point of the island and they recorded two other monads as well, amassing a total of more than 300 records. Rory's "plant of the day" was Polystichum lonchitis Holly Fern, the first time this plant has been recorded here for more than 100 years! Southern English botanists Fred Rumsey and Helena Crouch were in Rory's group and were particularly pleased to see Salix herbacea - check out the BSBI distribution map to see why - and Irish botanist Rory said he'd never seen it growing at such a low altitude (unless you know differently?) or so high (a whopping 5+cm!) - again, if you've seen a bigger specimen we'd like to know!

Planning tomorrow's itinerary

A few more botanists arrived on today's ferry, swelling our numbers to 20, so we'll be splitting into four groups and trying to zap all the monads we didn't reach today. Will we succeed before we have to catch the evening ferry? Check this blog tomorrow to find out!
