Insects have started to leave a bit of space in my brain for bryophytes to fill. It must be September. Barry recently sent me an updated tetrad map which reminded me that I still had some unfinished business in north-east Cardiff before starting on the western Vale and southern RCT.
Last weekend I spent a little while square bashing in the Glamorgan part of ST28H, which had only 5 species recorded. As expected it wasn't very exciting bryologically - the eastern part of Coed Wern-ddu produced a predictable list of woodland species. As I got back to the car I noticed a maize field with a convenient public footpath running through it, and a few minutes here proved more interesting than the hour spent in the woodland. The maize field margins were thick with bryos including Riccia glauca, R. sorocarpa, Trichodon cylindricus and Bryum rubens.
This tetrad is now up to a reasonable species total but needs some further work along the lanes and beside the River Rhymney to pull it up to a good total.
