BSBI Meeting at Freshwater West, Pembrokeshire

BSBI meeting at Freshwater West on Sunday 25 March. Six attended the walk. It was a superb sunny warm day to be out. 79 species were recorded including Erodium cicutarium (Common Stork's-bill) above.

 Below is the rosette of Arabis hirsuta (Hairy Rock-cress) on the dunes.

Polycarpon tetraphyllum (Four-leaved Allseed) at Pembroke Dock

As Polly said in the last blog I would be taking over as BSBI Welsh Officer. I would like to thank Polly for the wonderful job she did.

Haven't really had any chance to do much botany yet since I started back as Welsh Officer. It is nearly two and a half years since I posted here. 

Polycarpon tetraphyllum (Four-leaved Allseed) grows around the car park on the sea front by ASDA filling station, Pembroke Dock. Known here since Jon Hudson found it in 2009. This is the only extant site in Wales. Last recorded from Barry Docks, Glamorgan in 1927 by J.H. Salter and R.L. Smith. 

Polycarpon tetraphyllum (Four-leaved Allseed) is not the most stunning plant, the whole plant is green, very small, not always easy to tell if in flower or fruit as the heads are very small. 

Welsh Officer change

Today is my last day as Welsh Officer for the BSBI. I am relocating to Scotland with my family, and it just isn't practical to work in Wales! I am very glad that Wales will be welcoming back Paul Green, who has been Welsh Officer before and knows the ropes. 

Hymenophyllum wilsonii, Wilson's Filmy-fern

It has been a privilege and a pleasure to be employed by the BSBI for six years - I have learnt so much about Wales and Welsh botany. I will miss Wales, and the botanists, many of whom I now count amongst my friends. 

So that's it really - goodbye Wales and best wishes for the future. This from a recent visit to Merionethshire - near Abergynolwyn where we found a new record of Hymenophyllum wilsonii.

Caerdeon (Merionethshire) 2017

Setting off to Caerdeon last week I received an email which mentioned the "dire" weather forecast for the weekend. I was meant to be meeting a few others at lunch-time and heading up the slopes of Cadair Idris, and my heart sunk at the thought of a weekend botanising in pouring rain.

True enough, as I arrived in Dolgellau I met Andy, who had just purchased a new umbrella, and along with Flora and Phill we headed up. It was indeed a wet afternoon and by tea-time I was soaked more or less to the skin, but we had collected nearly 100 records, in a new monad, although we hadn't reached the "interesting" part of the tetrad! We headed back to Caerdeon to meet the rest of the group, find a hot shower, dry clothes and a hot dinner, followed by an evening of botany with microscopes, ID books and computers.

However, for the remaining three days I remained dry (apart from dampness in the feet, from bogs) and explored several upland areas of Merionethshire. On the second day we were lucky enough to be offered a lift a mile up a track in a 4x4, saving us a walk in. Exploring the shores of Creiglyn Dyfi, we found mostly species-poor upland sheep-grazed vegetation. However, in the lake we found Isoetes lacustris, with its diagnostic non-spiky megaspores (viewed later under a microscope).

Aran Fawddwy and Creiglyn Dyfi

Ascending below the crags of Aran Fawddwy, we found a range of "nice" plants including Succisa pratensis (Devil's-bit Scabious), Campanula rotundifolia (Harebell), two carnivorous plants - Drosera rotundifolia (Round-leaved Sundew) and Pinguicula vulgaris (Common Butterwort) and three species of clubmoss - Huperzia selago, Selaginella selaginoides and Diphasiastrum alpinum (Fir, Lesser and Alpine Clubmosses).

The next day we headed onto the slopes of Y Garn, through the western fringes of Coed y Brenin, and had a very fruitful day where we stayed entirely within one monad. However, after beginning in relatively "nice" forestry (mature, well-thinned trees with an understorey and diverse flora along the roads) we emerged into a beautiful bog [see blog background - from July 2017], full of Rhynchospora alba (White Beak-sedge) with a small colony of Wahlenbergia hederacea (Ivy-leaved Bellflower) and many other species. We then explored the ruin of a disused gold mine, which provided some wall ferns including Asplenium ceterach (Rustyback) as well as closely grazed nutrient-enriched turf for some common weeds including Bellis perennis (Daisy) which my group did not record on any other day! Climbing up through a Pteridium aqulilinum (Bracken)-covered boulderfield to reach the small crags, we discovered Hymenophyllum wilsonii (Wilson's Filmy-fern) under boulders and in cracks.

Examining a specimen - with lots of bracken.

For the final day, a small group of us headed a long way up a forestry road by car (thanks to Sarah's preparation in obtaining permission) to explore the area around Rhobell Ganol. As we were at nearly 500m altitude before starting we did not record such a diversity of species, but we did find the fourth clubmoss of the week - Lycopodium clavatum (Stag's-horn Clubmoss) in profusion as well as a really good range of sedges. The forestry in this area was a monoculture of Picea sitchensis (Sitka Spruce) which did not make for easy walking on our way back (working hard to create a circular route and cover as much of the tetrad as possible)! But it was another enjoyable day in good botanical company.

Glynhir (Carmarthenshire) 2017

At the end of June (after spending two days in Montgomeryshire) I was able to join the regular recording residential at Glynhir for two days. The first day the whole group visited Talley Lakes, which provided a really good range of sedges, although the lake appeared disappointingly eutrophicated, with bright green algae, most likely due to the presence of excessive numbers of waterfowl. However, there were a few sedges to look at, and Comarum palustre (Marsh cinquefoil) was flowering, which is always a treat.

The next day I headed with a small group to an un-recorded tetrad, north of Llandovery, which included somewhat varied habitats, from a small section of the River Towy next to a bridge, to paths and tracks around farmland, including small wooded areas and hedges. I always enjoy the interest of visiting a completely unknown square and although we didn't find anything earth-shattering, we had some interesting finds like this Fumaria muralis (Common Ramping-fumitory).

Montgomeryshire Intensive Recording Sessions

The botanical delights of west Montgomeryshire - a short report on Mont Flora Group's intensive recording sessions, 26-28 June 2017 (Guest post - contributed by Gill Foulkes, photos: Polly)

The weather forecast did not look promising; the intense heat of the previous week had abated and the barometer was dropping rapidly but in fact we escaped the anticipated deluge and over-trousers were mostly worn  to prevent a soaking from the wet vegetation.

On Day 1 we met at Cemmaes Road (some came from home, a couple were staying on a local caravan site and others in a local B & B) and split into three groups.  Kate Thorne, Glenys and Aubrey Evans recording locally and were treated to fine views of Cadair Idris as well as a good variety of plants and a bank of sand martins’ nests. The two other groups recorded further down the Dyfi, just to the west of Llanwrin in a secluded, wooded valley.  John Clayfield, Rachel Meade and Peter Foulkes found the Enchanter's Nightshade hybrid C. X intermedia.  Gill Foulkes, John Thorne and Sheila Turner were pleased to find Red Bartsia Odontites vernus in profusion along a farm track. The third group found Lesser Skullcap Scutellaria minor in a good bog.

The same groups (joined by Polly Spencer-Vellacott, BSBI Welsh Officer) all recorded in the Talbontdrain area on the second day. Intrepid as ever, John Clayfield, Rachel Meade and Peter Foulkes found Parsley fern Cryptogramma crispa and Brittle Bladder-fern Cystopteris fragilis on some old mine buildings. After a steep climb across thistly fields, Polly Spencer-Vellacott, John Thorne, and Gill Foulkes were rewarded with a small boggy area (someone's private nature reserve by the look of it) with a very large colony of Heath Spotted orchids Dactylorhiza maculata.  The third group found another good bog. 

Acaena novae-zelandiae (Pirri-pirri bur) - possibly a relatively new invasive in the area?

Two different groups in two different monads found Pirri-pirri bur Acaena novae-zelandiae; the second reported record for Montgomeryshire (the Montgomeryshire Field Society found it earlier this year near the Centre for Alterntaive Technology).  This plant can become especially invasive when it establishes in the wild.  Perhaps it should be listed on Schedule 9 of the Wildlife and Countryside Act in England and Wales before it's too late???

The dramatic landscape of Pistill-y-llyn

 On the final day, the group recorded at Pistyll-y-llyn where the Afon Llyfnant marks the border between VC46 (Cardiganshire) and VC47 (Montgomeryshire).  Mark Lawley (county recorder for bryophytes) and his friend Ralph Martin joined us and recorded 105 bryophytes (24 liverworts and 81 mosses). However, it was Ralph who spotted Brittle Bladder-fern Cystopteris fragilis in an old mine wheel pit.

Five colonies of Wilson's filmy fern Hymenophyllum wilsonii were found (and there were undoubtedly more) by John Clayfield in his relentless search amongst large boulders.  We had hoped to refind Mountain Male- fern Dryopteris oreades, but although a specimen was taken this has not been confirmed.  A steep, gravelly Calluna slope provided great habitat for a delightful small eyebright (possibly Euphrasia micrantha but still to be verified).  At the very end of the day and within sight of the cars, Kate Thorne found more hybrid Enchanter's nightshade C. X intermedia.

In total the three days produced over 1300 records and participants were introduced to the delights of west Montgomeryshire.  It is appropriate that the county flower, the delicate Ivy-leaved bellflower Wahlenbergia hederacea, was found in most monads visited.

BSBI Welsh AGM and ASM - part II

Last Wednesday evening at the Stamford Gate we were treated to a talk about Flintshire from the Emeritus Recorder, Dr Goronwy Wynne.

Dr Goronwy Wynne, the BSBI's
Emeritus Recorder for Flintshire

Goronwy has lived most of his life in Flintshire, and was recorder for over 40 years from 1963 to 2009. He spoke of the geology of the county and the altitude, and also talked of the way geology affects the vegetation on every scale from large to small. He also described some of the botanists that have worked in Flintshire, including anecdotes about Thomas Pennant. He finished off by telling us a few of the most common and rarest species in Flintshire. Goronwy was a colleague of my grandfather, who also contributed records to him for the Flora of Flintshire. He spoke without any PowerPoint or slides, but managed to hold the meeting's attention completely. 

On Thursday I joined the BSBI President John Faulkner, and Gillian Faulkner, and Oxfordshire VCR David Morris (see David's blog). We were allocated a square and delighted to find Maes Hiraddug SSSI (a Wildlife Trust Reserve). This grassland was lovely to see with many orchids: Dactylorhiza fuchsii (Common Spotted Orchid) and Neottia ovata (Common Twayblade). Then, as a special treat, we found a few fronds of Ophioglossum vulgatum (Adder's-tongue) and then a few more.

Having explored these meadows thoroughly we went on up a cycle track, into an old quarry, and down some lanes finding Fumaria capreolata (White Ramping-fumitory) in a hedge, we then eventually found access onto Moel Hiraddug, a limestone outcrop where we saw Helianthemum oelandicum (Hoary Rock-rose) over large areas near the summit. By this time the weather was threatening again, although we only had a few showers, and I failed to take any more photographs. 

I was unable to go out botanising on the final Friday, but it was wonderful to see so many botanists enjoying Flintshire, and to spend a few days in the field in good botanical company. I know Flintshire will be grateful for the extra records, which must be several thousands!
