this looks very much like the quay area we looked at today (looks rather different now!) there are some remarkable photos on line showing how this area once looked - search 'Copperopolis' |
Despite the apparent absence of Scopelophila, important metalliferous bryophyte and lichen communities are still present in Swansea, but these are under pressure from natural succession as-well-as ongoing redevelopment of the Copper Quarter. Thankfully steps are being made to safeguard the best examples of these remnants.
One plus from today was learning a new species, with the discovery of a strong population of Bryoerythrophyllum ferruginascens. Once the key characters were demonstrated to me by Sam, it immediately appeared so distinctive it was recognisable even at distance and we noted it in two tetrads. The dark red older leaves, with contrasting bright yellowy-green shoot tips create a distinctive hue on barren ground. This is one I suspect we will start seeing more frequently locally. First recorded by A.J.E. Smith at Craig-y-Llyn in 1961 and more recently Sharon Pilkington found it on the cliffs at Pennard, so it seems likely it can be found on suitable ground anywhere in the county.

That's a nice record lads, where exactly is that?
ReplyDeletedo you want me to ask the BGS folk about high Cu in soils to help locate potential sites. I think there is detailed soil geochem in Swansea area.....

ReplyDeleteNice to see the photos at different scales - that should be very helpful in trying to track down B. ferruginescens.
ReplyDeleteHi Gareth, if it's possible to identify sites where there are contaminated soils, this could prob very helpful thanks.
ReplyDeleteHi Barry, official answer is you can pay for the data ! However there is a report here http://nora.nerc.ac.uk/7019/ and also a section in “Urban geology in Wales:2”. I'll see if I can get a map to you of baseline Cu levels in Swansea...abroad at the mo, will see what I can do on return.
