Half a year gone

 And we have been active.

Members of the botany group were invited to update our records for Townhall Clock - Adoxa moschatellina from early March.

Adoxa moschatellina at Pwll y Wrach Nature Reserve, Talgarth

Results are pretty much now in (it is hard to spot and record from now on and often completely died back).

It was refound in 21 of the target monads (1km squares) with Gaye and Lynne finding the longest "lost" population near Crickhowell (last seen 1957). (All the updates were for squares where it had not been seen since 1999.)

There were records from 34 squares where the species had never before been recorded. Other records stretched from near Craig y nos (the species peters out to the south west there) to Cilmery near Builth Wells.

A welcome find

In October I received a report from Julie of Stag's-horn Clubmoss on Llangoed common. Several members of the recording group got there to check this out before I did and my group was initially dumbfounded to discover that we couldn't find it despite having good grid references. So after a while we decided to give up at one of the couple of  locations reported and set off for another only for Claire, who was leading, to call back that she had found it not 100m from where we had given up. Either the satellites were wonky that day or on the day of the earlier reports and we had been focussing too much on exact grid refs and managing to miss the populations while toing and froing!

Never mind - once found and with our "eye's in" we established that the population was very large - certainly a more established and abundant population than had been found in such a habitat in this county for many years.

The common itself is a delight and very carefully managed - the Bracken control (which was active at the time of discovery) being very effective at creating conditions for the Clubmoss to thrive.

And on the opposite bank of the stream the grassland was home to many wonderful Waxcaps - it's a well we had Ray with us to name them all.

Steph, who visited later on, found native White-clawed crayfish in the stream - adding to the good habitat rating for the area.

This picture alludes to our initial confusion!

Botany 2021 - part 2

The group have been very active in the latter part of the year, in many cases without my active participation.

On 25th June, we visited the Carex limosa site on the Vice County border previously discovered by Barry Stewart in 2001. This is at least 50km as the crow flies from the nearest other known sites near Swansea.

Needless the say the whole area was interesting and we also saw Cranberry in some profusion.

The beginning of July saw a group of us undertake a couple of days botanising in the remote north-west of the county, staying at the hostel at Dolgoch. It was a very wet weekend but we were delighted to encounter a field high up under Craig Carreg-fan with abundant Viola lutea.

Mountain Pansy or Trilliw y mynydd, Viola lutea

We climbed up higher and this view back just shows (centre lowdown) the zigzag path through bracken by which we approached the rocks above.

The group excursion outside the county this year took us to Cors Fochno just inland at Borth to see the Irish Ladies Tresses that now have settled there. It was agreat day and we enjoyed the other bog plants as well.

Botany 2021 in Brecknock

The Botany Group has not been entirely inactive with a lot of individual work proceeding from early on (within guidelines) and more recently we have done some group surveys.

Here are a few highlights so far.

Primroses on the canal

Common Whitlowgrass, Llysiau’r-bystwn ar or Erophila verna was abundant around Brecon and Hay

We found Hay-scented Buckler-fern, Marchredynen bêr or Dryopteris aemula near the Pyrddin river

Bird's-nest Orchid, Tegeirian nyth aderyn or Neottia nidus-avis
found in some quantity near Builth by R Gibbins

A Hybrid Sedge, Carex x prolixa or Carex acuta x elata found in wet Alder wood.

Too long for botany

Three of us set out on a long walk last Sunday from a car park near Abergwesyn to the Llyn Brianne Reservoir. Abergwesyn itself seems remote in our county and the drive between our start point and the place where we met the road again is a long one of over 10 miles over the "Devil's staircase". The walk up Cwm Culent and down Cwm Garach was "only" about 3 miles. I say only as it was quite tough going at times with much boggy and tussocky ground.

We returned through forestry and past the Cefn Fanog trig point (lost in the trees). This return route may have been a greater climb but was actually easier - thankfully.

(The trig point has been photographed by Trig Point baggers - see this, but we didn't bother visiting it!)

There was plenty to see including this very tall and flowering Bush Vetch. There was similarly robust Meadow Vetchling nearby.

Bush Vetch, Ffacbysen y cloddiau or Vicia sepium

There were several abandoned homesteads in the valleys and anthill meadows like this.

As can be seen the conditions were not good to start with.

Steph noticed some Bell-heather sheltering from grazing under Gorse:

Bell Heather, Grug y mêl or Erica cinerea

This species is surprisingly uncommon in the county and this record has added a green dot to this map:

We saw a fogbow as the mist started clearing around us.

Below Cefn Fanog

(A fog bow, sometimes called a white rainbow, is a similar phenomenon to a rainbow; however, as its name suggests, it appears as a bow in fog rather than rain. Because of the very small size of water droplets that cause fog—smaller than 0.05 millimeters the fog bow has only very weak colors.)

This is the view back from where we came once we got to the reservoir road.

And recently...

Outings in November have been walks with occasional records - to scout out habitats for more attention next year (we hope!)

The first was to Craig y Cilau, the cliffs and old quarries above Llangattock. The area is particularly botanically rich and we though we might just catch a very young Hutchinsia plant - they are flowering by March. 

Hutchinsia, Beryn y graig or Hornungia petraea (was known as Hutchinsia petraea) Avon Gorge

 - We didn't.

 But Alan did spot a small patch of this - not previously recorded there:

Ivy-leaved Bellflower, Clychlys dail eiddew or Wahlenbergia hederacea (Abergwesyn 2018)

and we identified several areas for exploration next year.

A week later saw us up between the Nedd Fechan and Afon Llia on the high ground, exploring an area known as Plas y Gors. The two rivers both get water from this watershed - and eventually meet up again at Pontneddfechan.

The forestry there used to cover a known Roman Fort site so it was good to see that area had been cleared and apparently not replanted (other areas near the fort had been). Whether the outline of the fort will eventually become clear again was uncertain !

 We soon passed the Maen Madoc standing stone.

The Maen Madoc or Maen Madog stone is adjacent to the Roman road Sarn Helen that runs across the Brecon Beacons.

It is thought to mark a Christian burial – the stone is inscribed on one side, the Latin inscription reading DERVAC(IVS) FILIVS IVSTI (H)IC IACIT – "Of Dervacus, Son of Justus. He lies here".

There was a dwelling called Plas y Gors and these are the ruins. We had managed to get through the bog referenced in the name by the time we saw it. It is difficult to imagine the existence supporting such a relatively grand dwelling. There is more information about the ruined farmstead, thought to be 18th or 19th century, on Coflein.

The bog to the left of it certainly is worth a summer visit and has yielded reports of quite rare plants in the 1990s. We saw that the trees that used to surround the bog have been felled which is good news for its future. 

Our most recent visit was to the Nant yr Hafod stream which comes off the southern slopes of Mynydd Llangatwg. It is our only site for Cornish Moneywort which I last saw in 2013. We were glad to find it still thriving there.
Cwm Nant yr Hafod
At the top of the Cwm the view to the east shows the just-discernible wall of the Cairn-Mound Reservoir dating from 1880 and abandoned by Welsh Water in 2005. This reservoir collected water destined for the Nant yr Hafod. To the right of the picture the remains of the Disgwlfa Tramroad crossing of the Nant yr Hafod can be seen.
Bing maps shows the reservoir very clearly from above:

We walked back down over the mountain with glorious views towards Llanelly Hill.

and came upon this inscribed stone which it took us a while to decipher:

The Hafod Inscribed Stones
(Go to the link for full details).

These Inscribed Stones that are found near Nant yr Hafod on the southern slopes of Mynydd Llangatwg above the Hafod Road/Cymro Road.

They were done by Jack Rushton. He was born in 1920 who was an upholsterer by trade.

The stone we saw is inscribed: "HE THAT SINNETH IS OF THE DEVIL BE YE HOLY”. There appear to me more letters beneath but we couldn't decipher them. We did manage to read almost all of the above.

There are many more similar stones to be found up there! 

Cornish Moneywort, Deilen gron Cernyw or Sibthorpia europaea

Botany in Brecknock, the story continues

We haven't been idle and this is the story from May to September. 

Our informal Brecknock Botany group carried on investigating their local flora individually all through to late June when we very tentatively started to go out in small, socially distanced groups. 

But before this… Working close to home with regular patrolling of the same routes soon paid dividends – I did not know Viola reichenbachiana (Early Dog-violet) was only 100 m from my home until this year. 

Viola reichenbachiana (Early Dog-violet or Fioled y coed) Forest Road, Hay

In late April I received reports of an abundance of Orchis mascula (Early-purple Orchid) just above Brecon well within several people’s exercise walking distance. I must say I had never myself encountered this plant growing like this.

In May Joan noticed Plantago coronopus (Buck’s-horn Plantain) in the main Brecon car park. This had been new to the county up on the Epynt early in 2015.

An Allium triquetrum candidate at Joan’s local churchyard at Llandefalle turned out to be Allium trifoliatum (Hirsute Garlic) on more careful examination / discussion online – proving, I hope, that we were not cutting any corners by working remotely. Paul Green was able to confirm remotely as referee and this is a new Wales record.

A walk along the Wye looking for early signs of the Persicaria mitis (Tasteless Water-pepper) found last year revealed a small population of Scirpus sylvaticus (Wood Club-rush) right by the water. It was last seen in about the same area in 1979 and is not at all commonly recorded in our county.

An exploration of Waun Ddu raised bog (at Craig y Cilau above Llangattock) by two of us resulted in several good records including Carex montana (Soft-leaved Sedge) and Eleocharis quinqueflora (Few-flowered Spike-rush). A week later, Anne finally found Hornungia petraea (Hutchinsia) on the cliffs above (a personal quest) - in dead form but still unmistakeable.

"It's dead, Jim"

I had noticed records for Gymnadenia conopsea (Fragrant Orchid), Platanthera chlorantha (Greater Butterfly-orchid) and Epipactis palustris (Marsh Helleborine) in 2015 near Brecon from an unknown name but confirmed by an eminent botanist. So, getting a request to go and visit from the landowner was welcome. I went as soon as I could to find a delightful wet meadow that the owners had left on minimal grazing since acquiring the property. Not only were there the Orchids (recorded in a Kew scheme “Orchid Observers” that asked for photographic submission) but there was Eriophorum latifolium (Broad-leaved Cotton-grass) as well as a host of other Brecknock Axiophytes. Even better, I was told that a neighbouring farm, had a small amount of Genista tinctoria (Dyer’s Greenweed) which had not been recorded in a long time in the area. Again a visit was most rewarding and benign neglect was the regime – this time the owner, who walked me through his fields to the wet site, apologised for the Yellow-rattle not being native – it turned out he had spread hay from a nearby farm he had worked on several years back thus introducing it in what I would say is an entirely natural way… This farm also had Epipactis palustris (Marsh Helleborine) and Eriophorum latifolium (Broad-leaved Cottongrass) as well as abundant Cirsium dissectum (Meadow Thistle).

I was able to find the roadside Epipactis palustris between Brecon and Hay on the way home – it had had a few fallow years but was back.
I was delighted that Tim Rich re-found our Orthilia secunda (Serrated Wintergreen) population complete with fruiting stems up on the top cliffs of Craig Cerrig-gleisiad. I was shown it by intrepid wardens in 2013 and Mike Porter had climbed down to it in the 1970s more than once with Ray Woods providing the confirmation for the 1980s. Not many of us have seen it close up since Beverly A Miles first recorded it in 1955.

Botany group member Anne likes to explore limestone near where she lives in Monmouthshire and found Erigeron acris (Blue Fleabane), initially in Monmouthshire Vice County (where they have lots) and later our side near Gilwern in first records for some time.

Undoubtedly the most exciting record of the year was Pyrola minor (Common Wintergreen) – possibly recorded our side of the border in 1911 but just as likely not. It gets close to us in Glamorganshire, but Arlene found it very definitely in the county at Abercraf and, it later transpired, in quite large numbers and area of distribution. The site is subject to development, but we were able to confirm a large and extensive population. (There are plans to relocate affected sensitive plants.)

A bryological exploration by Claire resulted in new records of Sagina nodosa (Knotted Pearlwort) and Lycopodium clavatum (Stag's-horn Clubmoss) in Cwm Callan . The Pearlwort was only the third record since 2000 in the county.

Finally, Tim Rich has been updating records of our endemic and rare Hieraciums with some in decline and others doing well. See his videos on You Tube.

While doing this, Tim reported a single plant high up on Tarren yr Esgob (cliffs above Capel y Ffin) of Rosa spinosissima (Burnet Rose). This was  a first record for a very long time for the county.
