BSBI Welsh AGM at Brecon

The Welsh section of the Botanical Society of Britain and Ireland holds an AGM Field meeting every year somewhere in Wales and this year was the first occasion for some time that the Brecknock area was host. (The formal business is soon dealt with and most of the meeting is about botanists getting together, field meetings and food.)

 I'll start with a couple of the pictures I took while out with members of the botany group checking the routes of the proposed field visits.

Llangorse was a natural choice for a field visit - it has a large proportion of our rarer species growing in and around it and always has surprises in store for a visiting botanist.

Joan and I were surprised to see a lot of Veronica catenata all around the periphery of the lake. It's normally found there somewhere but not usually in great abundance or, for that matter, particularity large plants. This year was different.

Pink Water-Speedwell, Graeanllys-y-dwr rhosliw or Veronica catenata

We also saw Celery-leaved Buttercup

Celery-leaved Buttercup, Crafanc yr eryr or Ranunculus sceleratus

The meeting proper started on the Tuesday afternoon but some arrived early and explored the area around the Ogof Ffynnon Ddu National Nature Reserve high up above Craig y Nos and Penwyllt where the limestone pavement supports some rare communities of plants. They first found Green Spleenwort there:

and later found it was a relatively common plant in the limestone.

Green Spleenwort, Duegredynen werdd or Asplenium viride

Here Martyn is pointing out a Lily of the Valley plant deep in a limestone "gryke". This is just one of the rather unexpected species to be found in the area.

Lily-of-the-valley, Lili'r dyffrynnoedd or Convallaria majalis

Meanwhile several of the visitors were setting up their exhibits at The Barn at Brynich - our venue for the meeting.

Andy Shaw in particular had an impressive display of the many rare plants he has in cultivation.

With this tray having some particularly difficult to find in the wild specimens:

Perhaps the star being this fern found only at a few South Western coastal sites.

Small Adder's-tongue, Tafod-y-neidr bach or Ophioglossum azoricum

The next day (after the formalities of the AGM in the early morning) groups set out to explore Vicarage Meadows, Cwm Cadlan and Stanner Rocks.

Here are some pictures of the group at Vicarage Meadows.

Walking through the abundant Dyer's Greenweed

Dyer's Greenweed, Melynog y waun or Genista tinctoria

(The group who went to Ogof Ffynnon Ddu National Nature Reserve saw this much more rare close relative on the Tuesday)

Hairy Greenweed, Corfanhadlen flewog or Genista pilosa

(I don't have pictures of the Cwm cadlan and Stanner vists but plenty was seen at both.)

On the Thursday most of the delegates went to Llangorse (the few exceptions mentioned below...)

And some of those went out on boats to sample the plants growing in the water.

The "professional boat"

The "amateur" boat (including myself taking the picture).

We saw:

Ivy-leaved Duckweed, Llinad dail eiddew or Lemna trisulca

and

Yellow Water-lily, Lili'r-dwr felen or Nuphar lutea

with, in the background:

Fringed Water-lily, Lili’r-dŵr eddïog or Nymphoides peltata
(The White water lily was also seen.)

But some serious work was done, finding two Charophytes and a variety of the leafy pond-weeds.

Shining Pondweed, Dyfrllys disglair or Potamogeton lucens

And we had a distant view of the other small party up on Cribyn and Pen y Fan seeing the Attenborough's Hawkweed and other gems on  the steep cliffs. (They are not quite visible in the picture below...)

(Taken from the boat when the party would have been on Cribyn - they had perfect weather as we did.)

Ray Woods came along later to join the land party at Llangorse but didn't catch up with them. He did however re-find this which had not been recorded since the 1990s.

Mare's-tail, Rhawn y gaseg or Hippuris vulgaris

Over the four days 1150 records for the county were made by BSBI botanists - a welcome contribution to our recording effort especially as the list included species we local recorders had missed. Amongst these records are 35 updated since before 2000 and 11 that had not been seen before in the area*.

Many thanks to the photographers who contributed many of the pictures above.
