This document offers an overview and some key examples of the work that took place during this peculiar year, along with some noteworthy sightings. We would like to take the opportunity once again to thank the County Recorders for their work and support to WSBRC and the recording community of Wiltshire and Swindon. Their expert knowledge is key in ensuring the quality of the data held by WSBRC, as well as assisting curious and enthusiastic recorders. We are pleased to welcome Rosie Ray, who is taking over the role of the Odonata County Recorder from the late Steve Covey. Gemma Harding wrote a few words about Steve for last year’s annual report. He is going to be greatly missed. Also, Wayne Clinch will be taking over the role of the Moth County Recorder. Dave Brotheridge and Wayne jointly covered the role since 2013, however Dave has been lately unable to continue. At the same time, Catherine Hosie will not continue with her role as the Orthoptera County Recorder as she left the County. We would like to thank them both for their long contribution. Last but not least, we would like to thank all the recorders that submitted their sightings, in spite of all the challenges of the Covid-19 pandemic. They are the cornerstone of biological recording, not just in Wiltshire and Swindon but in the UK as a whole. 3 WSBRC Update 2020 was overshadowed by the Covid-19 pandemic that inevitably also affected the work of WSBRC. The extensive fieldwork scheduled for the 2020 survey season as part of the Curlew Call project, had to be postponed. The other operations of WSBRC continued as normal, while staff moved to home working. Another significant development was the change in the manager’s role. Simon Sanghera left WSBRC in June 2020 and was replaced by Jo Wright as the WSBRC Biodiversity Information Manager in January 2021. We would like to thank Simon for his contribution and wish him all the best for the future. We would also like to thank Sam Stork for her support and for covering the role in the interim period. One major challenge in the coming year will be for Jo to lead on the Nature Recovery Network mapping for Wiltshire, ensuring the approach WSBRC takes integrates with work being done by other organisations within and bordering Wiltshire, and around the country. The NRN is an ambitious scheme that will result in the production of a map displaying areas that may be targeted for better, more joined-up habitat creation or enhancement and biodiversity net gain, enabling wildlife to thrive. Jo will also be looking at developing new partnerships and projects, and investigating new funding streams with the use of the WSBRC drone. She is very much looking forward to working with you all. Records The WSBRC database held 2,714,353 records at the end of January 2021. The majority of records are largely comprised of three taxon groups: Vascular (flowering) plants 41%, Moths 19%, and Birds 19% (Chart 1). This order has not changed since the last report. % of Total Records flowering plant 4% 4% moth 7% 41% bird butterfly 19% terrestrial mammal 19% fungus Chart 1. Taxon group representation in the WSBRC database, 31 January 2021 Record input increased significantly in comparison to the previous year. 445,795 records were imported during the 2020 calendar year. This number includes both new and older records that had to be edited and re-imported. You can refer to Chart 2 for further details regarding total number of 4 records imported per calendar year for the last five years (Please note that total numbers refer to records that are currently in our database).

Number of records imported per calendar year The majority of the records imported during 2020 were Vascular plants (55%) (Chart 3). This was the result of working on and catching up with old and new datasets received by Sharon Pilkington (Wiltshire Botanical Society). Also, in 2020 we started importing into our database verified records downloaded from the iRecord website. This is a significant change as iRecord is a very popular biological recording platform. We aim to continue the work that we started and gradually import all records submitted and verified through iRecord. % of 2020 Imports flowering plant 6% 6% bird 8% insect - moth 10% insect - butterfly 55% fungus 11% terrestrial mammal Chart 3. % of Imports per species group during 2020 5 Curlew Call Project: Jonny Cooper 2021 marks the third field season for the Curlew Call project. The two previous field seasons have enabled the identification of the breeding locations of the remaining pairs and the development of a network of volunteers to help us monitor these birds. There is also widespread support for this work amongst the local landowners and communities across the Braydon Forest. Despite the setbacks from Covid-19 in 2020 we were thrilled to be able to record a successful breeding attempt by one of the pairs breeding at Blakehill Farm WWT Reserve. We also produced a StoryMap to promote the project online, this will be regularly updated as the project progresses. Figure 1. Curlew Call StoryMap In 2021 we aim to catch up on fieldwork that was missed in 2020. The primary focus will be on locating nests and implementing nest protection measures alongside the regular monitoring of the pairs. Some limited tagging work will also be undertaken (provided the current plan for lockdown restrictions easing is adhered to). The focus of this work will initially be at Blakehill WWT Reserve with attempts to tag birds breeding at other sites if time allows. We also continue to work with landowners and are putting fundraising plans in place. 6 County Recorders’ Annual Reports In this section you can find the reports submitted by the Wiltshire and Swindon County Recorders and their recording groups for the 2020 season. For any further information, please contact the relevant recorder. Amphibians and Reptiles: Gemma Harding Records There is no doubt 2020 was an unusual year. Fortunately, this did not stop records coming in and actually may have increased them. A positive note for wildlife, amphibians in particular, is that there seemed to be a lot of people, myself included, creating ponds in their gardens. Good numbers of records were submitted via Living Record and verified by myself or members of Wiltshire Amphibian and Reptile Group (WARG). No unusual or significant records were noted. Although a record of an alpine newt in Swindon has been recently received. Active Recording and Monitoring Projects/ Events Toad patrols and monitoring: We continue to have concerns relating to developments and toads. In particular, the site at Wichelstowe is still having problems with toads trapped in gully pots which we continue to rescue and raise the issue with the developers. Toads, despite being in decline and a priority species they are still not receiving the consideration they need. Being at home more during 2020 allowed me to monitor the

This issue contains the first village flora to be included. Barbara Last has systematically recorded the plants growing in Berwick St James, and her article gives an account of her findings. Hopefully, it will inspire others to do similar work in their own localities. Our second article is the first systematic account we have published on the vegetation of Salisbury Plain. In this case, Kevin Walker and Richard Pywell describe the grassland communities of the MoD Training Area. Kevin and Richard can be contacted at the Institute of Terrestrial Ecology, Monks Wood, Abbots Ripton, Huntingdon, Cambs., PE17 2LS. Tel. 01487 773381.Fax. 01487 773467. Email; [email protected] Innovation is complemented by continuity. Rob Randall’s article continues his account of the history of recording the many different species of bramble in Wiltshire. His account brings us more or less up to the present day. It is hoped that the next issue will contain what is effectively an up-to-date bramble flora of Wiltshire. As in previous issues, a selection of the Society’s plant records is included.

  • Newsletter 82 Page 1 of 14 Ground-Breaking Format, Incorporating the Gathering and Disseminating of Records and Information About the Moths of the County
    Norfolk Moth Survey c/o Natural History Dept., Castle Museum, Norwich, NR1 3JU Newsletter No.82 November 2012 INTRODUCTION It has been, as they say, a funny old year. Anyone hoping for an upturn in mothing fortunes following the topsy-turvy summer of 2011 was likely to have been disappointed. In fact, I don’t think I can recall any other year since NMS started in 1985, when so many of our planned field meetings have succumbed to adverse weather conditions. Lynford was postponed, Brettenham was a non-event, and our joint meeting with the Suffolk Moth Group for National Moth Night was cancelled. One suggestion resulting from all this is that in future we should encourage everyone to check information on the website on the day of the event if conditions are likely to be unfavourable. Hopefully that may prevent un-necessary journeys from being undertaken. Having said all that, the remaining field trips were fairly successful, and reports on them are included in this newsletter. As always, we are grateful to all of you who have supported these events in any way. Given the circumstances, it is hardly surprising that migrant species were also relatively sparse in appearance this year. Dave Hipperson has compiled the usual list of records received so far. If you have any outstanding migrant records, do please send them in as an additional list will be included in the newsletter next spring. One of the more exciting migrants that did turn up was a new county record in the form of the pyrale Sclerocona acutellus, the so-called Thatch Pearl.

Diese taxono- mische Einheit umfasst in Europa innerhalb der Schmetterlinge die artenreichste Familie der Noctuidae (Eulenfalter), ebenfalls die Nolidae, Notodontidae, Euteliidae und nach neuesten taxonomischen Erkenntnissen auch die Familie der Erebidae. In die Letztere wurden mittlerweile auch die ehemaligen Familien der Arctiidae (Bärenspinner) und der Lymantriidae (Trägspinner) als Unterfamilien inkludiert. Die Neuaufstellung erfordert die Zusammenführung der Abb. 1: Auch der Schwammspinner (Lymantria dispar) zählt mittlerweile zu den ursprünglichen Sammlung des Landesmuseums mit den Erebidae und somit zu den Eulenfaltern im weiteren Sinne.

  • Wiltshire Botany 1, 1997, Pages 1-2 EDITORIAL Wiltshire Botanical
    Wiltshire Botany 1, 1997, pages 1-2 EDITORIAL Wiltshire Botanical Society was founded in 1992. A large group of enthusiasts had been recruited and trained to observe and record wild plants in Wiltshire during the work for the 1993 Flora of Wiltshire. It was felt to be important to maintain this joint interest and activity. The Society was therefore inaugurated to act as a focus for its continuation. The aims of the Society, as enshrined it its constitution, are; • To encourage anyone interested in plants, both beginners and knowledgeable botanists. • To be a forum where members can learn more about plants and exchange ideas and information, eg by holding field and indoor meetings and by producing a newsletter. • To organize projects and working groups to study aspects of the Wiltshire flora. • To encourage a respect for and conservation of the Wiltshire flora and habitats. • To study and extend knowledge of the Wiltshire flora. The Society has maintained its membership, which now numbers 80-90, and has organized a consistently interesting programme of events. An informative and interesting newsletter has appeared regularly. A wide range of detailed work on the Wiltshire flora has been undertaken. To encourage and coordinate this work, a Science Group was set up in 1994. Its aims, summarized from the more comprehensive account in its minutes, are: • To encourage, advise and guide recording activities. • To play a part in the planning of meetings and workshops to maximise their educational impact. To facilitate identification of plant material. • To organize and publish records. • To ensure that surveys and other projects are carried out in as effective and scientific a manner as possible.

  • Two New Records for the Appalachian Grizzled Skipper (Pyrgus Wyandot)
    Banisteria, Number 24, 2004 © 2004 by the Virginia Natural History Society Status of the Appalachian Grizzled Skipper (Pyrgus centaureae wyandot) in Virginia Anne C. Chazal, Steven M. Roble, Christopher S. Hobson, and Katharine L. Derge1 Virginia Department of Conservation and Recreation Division of Natural Heritage 217 Governor Street Richmond, Virginia 23219 ABSTRACT The Appalachian grizzled skipper (Pyrgus centaureae wyandot) was documented historically (primarily from shale barren habitats) in 11 counties in Virginia. Between 1992 and 2002, staff of the Virginia Department of Conservation and Recreation, Division of Natural Heritage, conducted 175 surveys for P. c. wyandot at 75 sites in 12 counties. The species was observed at only six sites during these surveys, representing two new county records. All observations since 1992 combined account for <80 individuals. Due to forest succession and threats from gypsy moth control measures, all recent sites for P. c. wyandot in Virginia may be degrading in overall habitat quality. Key words: Lepidoptera, Pyrgus centaureae wyandot, conservation, shale barrens, Virginia. INTRODUCTION wyandot) in Virginia. Parshall (2002) provides a comprehensive review of the nomenclature and The Appalachian grizzled skipper (Pyrgus taxonomy of P. c. wyandot. Most authors classify this centaureae wyandot) has a rather fragmented range, skipper as a subspecies of the Holarctic Pyrgus occurring in northern Michigan as well as portions of centaureae (e.g., Opler & Krizek, 1984; Iftner et al., Ohio, Pennsylvania, Maryland, West Virginia, and 1992; Shuey, 1994; Allen, 1997; Opler, 1998; Virginia; isolated historical records are known from Glassberg, 1999; Parshall, 2002), although some Kentucky, New York, New Jersey, North Carolina, and lepidopterists treat it as a full species (Shapiro, 1974; the District of Columbia (Opler, 1998; NatureServe, Schweitzer, 1989; Gochfeld & Burger, 1997).
