Penyclawdd Wood (SO40J/P) is part of my Dingestow Court home patch, and was one of the first areas where I recorded bryophytes 17 years ago. Since then I have made many visits, but these largely stopped when Bea was born (7 years ago) and I have only looked once since 75% of the wood's conifer blocks were clearfelled in 2012. That visit, in 2013, produced Dingestow's only
Sphagnum record: a single patch of
S. subnitens. Yesterday I checked two other blocks of clearfell, one of which has been almost overwhelmed by
Ulex gallii (!!) whereas the other remains relatively clear. There was no
Sphagnum, but species of note in the clearfell/regrowth areas included
Archidium alternifolium (photo),
Fissidens exilis (photo) and
Fossombronia pusilla.
A damp, clay track that was once heavily disturbed by farm traffic is now kept open by pedestrians (and deer) because vehicles use the tracks that were put in for conifer extraction. The sedge-rich vegetation on the clay track holds locally abundant Campylium protensum (photo), scattered Bryum pseudotriquetrum (photo) and some non-fertile Weissia with decumbent shoots that is probably W. squarrosa (photo).
There were various blocks of broadleaved woodland among the conifers, and these now stand proud of the clearfell. One area of 30 year old birches surround a spring where
Chiloscyphus pallescens and
Fissidens adianthoides grow alongside
Valeriana dioica and various other calcicoles. The floor of this 'birch grove' holds abundant
Rhytidiadelphus triquetrus (very rare around Dingestow) and is the only site locally for
R. loreus (photo) (a few shoots 15 years ago, but now a couple of small patches) and
Loeskeobryum brevirostre (photo) (one hand-sized patch about 7 years ago, but now abundant over >5x5m!).
It is fascinating to be able to revisit this very diverse area of woodland after so long. It used to support White Admirals, Glow-worms and many different moth species. More to revisit over the next several years.
