Deja vu on the Blorenge

Graham's discovery of Tritomaria exsecta got me wondering what else might be present on the slopes of the Blorenge, so I set out for a couple of hours searching the north-western and northern slopes this afternoon.  I have looked at the upper crags and limestone quarries previously, so stuck to the lower tramroad until I reached Cwm Craf.  Bryophytes were slightly disappointing, to be honest, with just 5 additions to tetrad SO21R (taking the total to 198 taxa), but I was amazed to find some Tritomaria on a small rock among bracken at SO26881266.  I have no idea where Graham was looking, but my rock is definitely different to the one in his photo!  My Tritomaria also seems to be different: many of its gemmae are >15um wide, as are many of its lamina cells, so it appears to be T. exsectiformis new for VC35!!

Like Graham, I was rather distracted by lichens.  Ramalina fraxinea was on a rowan and an ash, and appears to be new for VC35; R. calicaris was on the same ash, and the only previous county record was from Caerleon in 1985; Physcia leptalea was on rowan, and likewise was recorded once in 1985; Usnea articulata was on a hawthorn, representing the 3rd county record; and Usnea cf. fulvoreagans on an old fingerpost appears to be new for eastern Wales.  Sphaerophorus globosus on the same rock as the Tritomaria, and Pseudevernia furfuracea on the same signpost as the Usnea also have very few Monmouthshire records.  In truth, though, Monmouthshire is extremely under-recorded for lichens!

A weekend on Lundy - mosses and liverworts

Clare and I spent the bank holiday weekend on the magical Lundy Island, sailing from Bideford after dropping Bea and Johnny with their grandparents in Sussex.  South Wales was visible from Lundy (when it wasn't raining), so perhaps it isn't stretching the Blog title too much to mention some of the bryophytes I bumped into during our visit.  Clare enjoys walking for walking's sake, whereas I walk to get to recording sites, but we had a good compromise where Clare strode between headlands and waited with a book whilst I made a few stops in between; we did plenty of walking together too.

On our first day included a walk up the west coast of the island as far as the Halfway Wall.  The path down to the Battery produced Anthoceros punctatus (photo) and Tritomaria exsectiformis (photo), whilst rocky heathland a little further north held Kurzia sylvatica.  A flushed area (photo) with Bryum alpinum also supported Fossombronia sp with violet rhizoids, which I suspect is F. maritima; I'm growing some on in a tube in the hope of sporophytes.  Pogonatum nanum (photo) was fruiting beautifully on a bank nearby.

Our second day was marred by heavy rain in the morning, but we ventured out a few times along the east side of the island.  Bryological highlight was Frullania teneriffae (new for VC4) alongside Scapania gracilis in the VC Quarry (photo).  Exploration of the wooded Millcombe valley produced Epipterygium tozeri, Pohlia lutescens and Plagiochila asplenioides, whilst Schistidium rivulare was a surprise on rocks in the Quarter Wall Pond.

Our third and final day involved a stomp along 'The High Street' to the north end of the island (4 km away from The Village) followed by a walk back along the east side.  Lepidozia cupressina (photo) and Dicranum scottianum (photo) grew together on a tor just south of Gannets Coombe - like Dartmoor in miniature - and there were Cephalozia connivens and C. lunulifolia nearby.  Salt-sprayed turf near the northern lighthouse held Hennediella heimii, and a Bryum nearby looked interesting but was unfortunately non-fertile.  Finally, an exploration of Landing Bay while we waited for the boat back to the mainland produced Schistidium maritimum and Weissia perssonii at last: most of the island is too steep to allow descent to the maritime areas favoured by these species.

I don't actually know how many of the 100+ species that I recorded (with 8-fig GPS readings) were new for the island.  The BBS dataset seems extremely incomplete, especially for liverworts, with some broad-date 20th century records and a list made by Mark Pool in 1997; I added nearly 30 species to the hectad tally according to the BBS data.  However, Jean Paton's data from her visit in 1975 does not appear in the BBS dataset and several of my 'additions' were already recorded by her (unsurprisingly!), and Jean spotted several liverwort during her "few hours" on the island that I missed.  The Lundy Field Society reports may include other liverworts, but the issues that I looked at didn't have anything.  Mosses seem to be even more under-recorded, and the only reference I can find is a list from 1959 with IDs by Michael Proctor, and it is that list which forms the basis of the BBS data.  I will, of course, make sure that my records go to the BBS and the Lundy Field Society.

As well as the bryophytes, we saw Lundy's famous Lundy Cabbage (none of the plants by the paths were in flower unfortunately), Balm-leaved Figwort, Primrose Peerless and Ophioglossum azoricum.  Star lichens were Teloschistes flavicans and Anaptychia ciliaris subsp mamillata.  Bird highlights were the Lundy rarities Yellowhammer and Stock Dove, which I found during our wanderings, and there were various Warblers around, Black Redstart, Pied Flycatcher, Whimbrel etc.  Lundy really is a fabulous place for a wildlife-rich holiday!
