Please be aware that the Ashleworth Ham field meeting scheduled for the 1st Feb has had to be postponed for a second time due to flooding. We hope to reschedule for a new date soon.

Guy Meredith took up the challenge of recording Gloucestershire micro-moths in 2002 and has made a large number of new county records including many of national significance. He calls himself a Lepidoptimist – an optimistic moth-man. He has written this report, to be updated periodically, where his finds are discussed together with information on his techniques and a great deal of insight into the pleasures and problems of being a lepidopterist.

Dates for your diary… The following events will soon be added to the upcoming events list once further details are available.

Thirteen members and friends met on a wet November morning to be led by Robert Cullen of Forestry England to a beaver enclosure in the middle of the Forest of Dean.

A fence was set up here in 2024 to enclose 12 hectares of mixed woodland cut through by the Perryhay Ditch. Previously this brook ran only in winter or after rains and was usually dry over the summer. The two beavers introduced here – the female from a Scottish release site and the male from Devon – quickly paired up and had three kits this year.

We did not expect to see beavers, but there was plenty of evidence of their presence. Within about 20m of the stream we came across frequent long poles with pointed ends lying on the ground. The beavers had felled small trees, gnawing round the base, stripping off the nutritious bark and nipping off the side branches. With this brash they had created about 10 dams along the brook using the twiggy material from the trees packed with mud. Thus the brook held water even through the drought summer of 2025.

Beavers need the pools not for the fish (they are strictly vegetarian) but so that they have a protected underwater approach to their dens.

Rob has kindly provided footage from the trailcams showing dam repair, an adult with kit eating bracken, the pair play-fighting (apparently beavers are quite capable of killing each other but this is just having fun, here watched by wild boar). The goshawk and squirrel footage was captured very shortly after the kits were born and the immediate thought was that one had been taken, so it was with some relief that it was seen to be a squirrel.

The planned GNS field meeting at Ashleworth Ham at 9.30am on Sunday 14 December 2025 has been postponed for the moment because of forecasts by the Environment Agency of flooding in the area in the next few days. This flooding is likely to cause deep flooding on the Ham Road between Ashleworth and Tirley, and to make the Gloucestershire Wildlife Reserve at Ashleworth Ham impossible to reach. It is hoped to rearrange the field meeting at a later stage in the winter when the floodwaters have receded.

This was an evening meeting at the National Trust’s Sherborne estate using thermal imagers for night vision.  Despite near-continuous drizzle (which degrades the images) we were able to spot badgers, a pair of Little Owls, other unidentified owl species and lots of rabbits.

Using the more traditional method of dazzling (like ‘lamping’ when hunting rabbits) two of our licenced bird ringers were able to capture and ring a Common Snipe.

Another device used was an ultra-violet torch, which showed up lichens and these Mycena fungi, probably M. inclinata.
