Each summer my local biological records centre, SEWBReC, runs a series of biological recording field days, partly to introduce members of the public to the world of biological recording, allowing them to rub shoulders with wildlife experts and learn species identification skills, and partly to record the biodiversity of particular areas. Last Thursday I went along to the field day-come-bioblitz at the Cwm Saerbren Woodland, adjacent to the small town of Treherbert at the top of the Rhondda Fawr Valley.

Though the turnout from the locals was disappointing (not a single person!) and despite the sometimes heavy rain (a common feature up the Valleys), we had a great day. With the SEWBReC crew, a couple of guys from Natural Resources Wales, and a few of us volunteers from the Mary Gillham Archives Project, we stomped around the trails of Cwm Saerbren, recording all we saw. And, after meeting up back at the town to identify and write up our afternoon list and then filling up on hot chips from the local takeaway shop, we also got out with the bat recorder and had moth-attracting lights running to see what flying critters we might find. All up, once everything is IDed, I reckon our list will be well over 200 species. Not bad for a day’s work!
