One of the issues under discussion has been a revision of the Society’s “Rules”, which have not been amended for about twenty years. We plan to propose some modest amendments at the Annual General Meeting in March 2015, so that the Rules reflect better the role undertaken by GNS; among other things, we need to recruit new Committee members with new ideas and new outlooks; I would be very glad to hear from any member willing to put his or her name forward. In the meantime, the Society has continued its tasks of observing, recording and publishing the county’s flora and fauna. During the summer, Richard Lansdown’s “Provisional Red Data Book of Gloucestershire Bryophytes” has been published as a special number of “The Gloucestershire Naturalist (TGN)”. The book’s importance goes well beyond the limits of the county, and we hope it may be a model for other counties; the Society congratulates Richard for publishing such a valuable book on a neglected group, and one that is so readable and interesting for the non expert in mosses and liverworts. Furthermore, another issue of TGN, number 26, has just appeared, with the reports on 2013 from most county recorders on their speciality. At a recent meeting of the GNS Scientific and Publications Sub-Committee, plans for new issues of TGN were mentioned, including a new volume on the county’s dragonflies, and new floras of particular areas of the county (the Forest of Dean and Alney Island). The preparation of the next county Bird Report (for the year 2013) is underway, in the very capable hands of Gordon Kirk, one of the authors of the “Birds of Gloucestershire”. Much of the work of the recorders goes on quietly and unobtrusively behind the scenes yet collection, storage and analysis of data on different taxa is a crucial task, undertaken in conjunction with the Gloucestershire Centre for Environmental Records. It is clear that the work of the recorders is one of the crucial aspects of the activities of GNS, and much of the discussions of the Executive Committee centre on how best to support the Recorders. Another activity that has been continuing through the summer is the series of Wildlife Training Courses, organised in conjunction with Gloucestershire Wildlife Trust (GWT). More than a dozen such courses have been held on a variety of subjects, and the response was such that we plan to hold similar courses again next summer. The response from participants has generally been enthusiastic, though as yet we do not seem to have recruited many new members, nor awakened too many new vocations as naturalists/recorders. We are reviewing the results with GWT, to see how we might improve future planning and content, and indeed are keeping in very close touch with GWT on a variety of joint activities. The new Butterfly Conservation reserve at Rough Bank, a major site for butterflies and plants of limestone grassland on the edge of the Cotswolds, was duly opened in late August, in the presence not only of a goodly number of GNS members, but also of the new Chairman of Natural England (NE). He said that his vision was for NE to be a respected scientific body, that provided the Government with objective information on the urgent conservation issues of the day: we shall be watching his progress in this ambitious aim! The reserve, on the Cotswold scarp near Cranham and Birdlip, is now open to the public, and a lovely site it is too, altogether worth a visit. 3 GNS NEWS DECEMBER 2014 Another issue, which has taken up much of the GNS Executive Committee’s time over the last year, is the plan to construct a new college, road and other facilities at Cinderford Northern Quarter. The Forest of Dean District Council’s Planning Committee duly gave the green light for the project to proceed in early November. Andrew Bluett, who has reported extensively on this issue in GNS News, and I attended the meeting; while the environmental and conservation issues were given a broad airing (notably through a very balanced presentation made on behalf of the Dean Natural Alliance) Councillors were clearly swayed by the promises of infrastructure and jobs on this complicated site where open cast mining has occurred in the recent past. However, there is still much to be done before the project is completed and GNS will continue to make its voice heard, notably in insisting on full mitigation and compensation for any losses to conservation. Our programme of field meetings continues through the winter, with many of the meetings aimed at further investigating some of the questions posed about particular sites: thus, to follow the meeting at Plusterwine where we looked at saltmarsh creation by the Environment Agency (in which GNS has taken part in the recording), we shall be organising a meeting at the GWT reserve at Hobbs Quarry, in order to contribute new data to the Management Plan. And please don’t forget the wide-ranging series of indoor meeting, organised in Cirencester by the Cirencester branch. All members are welcome and the talks present a fascinating variety of illustrated presentations on all aspects of natural history. Finally, a wintry thought as the evenings draw in; in the Severn and Avon Vales, wet fields and full ditches are beginning to appear again, and with them the annual arrival of geese from further north. Sadly, not so many of the ‘whitefronts’ of Russian origin which used to occur, but mainly Canada and greylag geese. Many naturalists turn up their noses at these “feral” or half-wild species yet I defy you not to be impressed by the spectacle of a thousand of these birds, with the rush of wings, the noisy calls, the interactive behaviour, and the sheer numbers. I have recently started finding colour ringed Canada geese marked in the summer at a roosting site on Lake Windermere, in addition to the ringed greylags which are born in the Dean and South Wales, migrate to Glasgow to moult, then return to winter in the vale; take a look for yourselves, I assure you it’s a fascinating sight!

Chairman, GNS GNS NEWS DECEMBER 2014 4 The weather July to September 2014 Most of the UK had a warm, fairly sunny and dry July; it was the eighth successive month with above average temperatures over the UK as a whole and 19 July was the hottest day of the year so far with temperatures of 32°C in Kent. Nationally, rainfall was below average, making it the driest July since 2006, with only 57% of the average rainfall in the South West and South Wales, and only 70% in the Midlands. Winds were mostly light, but a “Spanish plume” spread warm air northwards across the UK on 20 July and many places had large amounts of rain in short periods and lightning storms. In the Severn Vale the weather was warm and dry for much of the month, with maximum of 29°C in Gloucester on 24 July. At a national level, the UK had its coolest August since 1993 and its wettest since 2004. There was a prolonged cool period between 9 and 28 August, during which the temperature did not exceed 25°C anywhere. These cool and wet conditions were largely due to low pressure, including the remnants of ex-hurricane Bertha which tracked across the UK on 10/11 August, while ex-hurricane Cristobal passed on 29/30 August, going much further to the north. It was a wet month, much wetter than July and the rainfall for both the Midlands and southwest England and Wales was about 140% over the 30 year average. The heaviest rainfall, in the wake of hurricane Bertha was 21mm in Gloucester. The weather relented on 31 August, a fine sunny day, at last with the temperature reaching 23°C in Gloucester. The total Gloucester rainfall in August was well above average at 76mm. September was dominated by high pressure, bringing fine and settled early autumn weather, perhaps a result of the jet stream remaining further to the north of the British Isles than usual. There were only a few short interruptions to this stable picture: heavy rain in northeast Scotland on 7 September, localised thundery rain in southern England on 19/20 September and some thick fog on 23, 29 and 30 September.
