Definitely one to look out for: Every single aquatic plant pot being sold in Wyevale, Llansamlet was contaminated with Valdivia Duckweed (Lemna valdiviana), so it’s not difficult to see how these new aquatics spread. Note also most pots were similarly contaminated with Water Fern (Azolla filiculoides)!

By the 4thJuly the Black-tailed Godwit flock at Penclacwydd WWT had increased to 236 with the following four colour-ringed birds noted by Wendell Thomas:
L: Green/Red, R: Lime/Red
L: Lime/Red, R: Green/Red flag
L: White/Orange, R: Orange/Red
L: Orange/Yellow, R: Orange flag/Yellow
Details of LR-GRf were received yesterday that reveal it was ringed in north-east Iceland on 10th July 2009. It has spent every subsequent winter at Pontevedra, Galicia in NW Spain, Wendell’s sighting being the first away from this locality. All colour-ringed sightings of Black-tailed Godwits seen at WWT are shown above with LR-GRf shown by the thicker yellow line. Still awaiting details of the other three.

Whilst beachcombing with staff and nursery kiddies from Townhill Mo Henwood photographed this stranded organism that I was asked if I knew what it was. I’m no expert on marine fauna, but it looks very much like the Blue Stalked Barnacle (Lepas fascicularis). Unlike the Gooseneck Barnacle (L. anatifera) reported earlier on this blog here, the Blue Stalked Barnacle doesn't attach to floating objects, but manufactures its own foamy float upon which it drifts around the oceans. I’m curious if anyone else has come across this species?

To achieve better coverage of the lakes and cliffs at Craig-y-Llyn we split into two groups; Julian leading a group to Llyn Fawr (SN917034) with Charles and myself leading a group to Llyn Fach (SN905037). The following notes and images are from the Llyn Fach group taking on the midges of Neath Port Talbot. On our approach to the lake we were lucky to see a Chinese Muntjac (Muntiacus reevesi) crossing the forest track, this being my first observation of the species in the county.
|Common Apple-moss (Bartramia pomiformis) frequent in cliff crevices|
With the level of lake being high, sampling was difficult, but we did manage to find several of the key species for which the lake is noted including Spring Quillwort (Isoetes echinospora) and Water Lobelia (Lobelia dortmanna).
fish tank photography is cheaper than underwater gear!
The fringe of emergent vegetation included stands of Bottle Sedge (Carex rostrata) and Water Horsetail (Equisetum fluviatile) grading into Molinia/Sphagnum mire, where a Small Pear-bordered Fritillary (Boloria selene) was noted during a short sunny spell.
|Small Pearl-bordered Fritillary|
The north-facing scree slopes and cliffs above the lake provided the most interest with noteworthy species logged including Beech Fern (Phegopteris connectilis), Brittle Bladder-fern (Cystopteris fragilis), Mountain Male-fern (Dryopteris oreades), Oak Fern (Gymnocarpium dryopteris), Common Butterwort (Pinguicula vulgaris) & Fir Clubmoss (Huperzia selago).
Attendees at Llyn Fach: Alison Heath, Charles Hipkin, Ceri Richards, Kaz Wilkinson, Vanessa Williams & yours truly.
