This lunchtime I paid my annual winter visit to the Leucodon colony on Sycamore in Bute Park. I was half expecting to be penning an orbituary after the decline observed last year, which was at least partly caused by physical damage due to tree climbers. But the Leucodon is hanging on, just. It has declined even further since last year, with just a few wispy shoots present around the edge of this formerly fairly dense patch. The photos below are sequential from 2014 to 2017.
Will it still be there next year I wonder.
On the cycle home, some grab samples from tarmac added a couple of species for ST17U: Didymodon insulanus and Brachythecium mildeanum. There was a lot of Dialytrichia mucronata and a bit of Syntrichia latifolia present too. I still can't find any Ceratodon in this tetrad!
