This document offers an overview and some key examples of the work that took place during the year, as well as significant sightings and events. We would like to take the opportunity to thank our County Recorders for the invaluable support that they offer to WSBRC and the recording community. Their expert knowledge is key to the maintenance of reliable biological data, and their love and commitment to recording continues to inspire a new generation of recorders. We would also like to welcome Claire Jones to the County Recorder’s team, who has replaced Nick Adams as the County Recorder for Birds. At the same time, we would like to thank Nick for his contribution and support all these years. Last but not least, we would like to thank all the recorders that submitted their sightings. Their contribution is as crucial, as biological recording relies on volunteer recorders. The importance of those records in monitoring species and environmental change, as well as in informing conservation and planning decisions, cannot be overstated. Last year we were very saddened by the loss of Steve Covey, the Odonata County Recorder. Gemma Harding was very kind to write a few words about Steve, as the current WSBRC members did not have the pleasure of meeting him in person. Steve Covey (29 Jul 1955 - 17 Jun 2019): Gemma Harding This year’s report would not be complete without mentioning Steve Covey – dragonfly expert, dedicated recorder and all round great guy. Sadly Steve passed away on 17th June 2019 leaving a huge hole in many people’s lives and certainly within Wiltshire’s wildlife knowledge. Steve was very passionate, not only about dragonflies, but all wildlife and was a great naturalist and photographer. He will be sorely missed by us all and we will remember him with every passing dragonfly and in all the great work we aspire to do. 3 WSBRC Update WSBRC had another busy year. The main highlight of 2019 was the launch of the Curlew Call project that aims to protect this iconic species – you can read more about the project in the relevant section of the report. A new big project that WSBRC will play a leading part in is the creation of a Nature Recovery Network for Wiltshire. The project is at the planning stage and we are very excited for the coming year. Records The WSBRC database held 2,570,435 records at the end of March 2020. Record input increased in comparison to the previous year. You can refer to Table 1 for further details regarding total number of records per year and per taxon group (Please note that the year totals do not refer to calendar years. The dates that the totals were extracted vary each year. However, they do give a general idea of the data increase). The majority of records are largely comprised of three taxon groups: Vascular (flowering) plants 40%, Moths 20%, and Birds 20%. This order has not changed since the last report (Figure 1). flowering plant 4% insect - moth 4% 6% bird 40% insect - butterfly 20% terrestrial mammal fungus 20% moss Figure 1. Taxon group representation in the WSBRC database, 31 March 2020. 299,260 new records were imported during the financial year 2019 - 2020. The majority of records imported were Vascular plants (53.4%), Birds (21.7%) and Moths (20.7%). The aim for this year is to identify further data sources, increase the flow of data that reach WSBRC and improve the data processing efficiency and capacity. 4 Table 1. The number of records per taxon group within the WSBRC database. 5 Curlew Call project: Jonny Cooper WSBRC began its Curlew Call project in 2019 as a response to the apparent decline of breeding Curlew in the Braydon Forest and the concern of landowners that the birds could disappear from the area. The initial phase of the project identified the locations of the remaining pairs and built up strong relationships with the local landowners. At the end of 2019 the project received £5,500 worth of funding from Wessex Water and the British Birds Charitable Trust to undertake tagging work to understand how birds are using the Braydon Forest area during the breeding season. This was to be undertaken in 2020 alongside an expanded fieldwork program to monitor nests and install nest protection measures in the Braydon Forest and try to locate any remaining pairs across north Wiltshire. Unfortunately, this work was stopped by the Covid-19 outbreak. Both Wessex Water and the British Birds Charitable Trust have extended the delivery period for the grant to include the 2021 breeding season, so the tagging work alongside the wider fieldwork program has been moved to next spring. Going forward, the project will begin to work with landowners to implement Curlew friendly management practices and look for new ways to raise funds. 6 County Recorders’ Annual Reports In this section you can find a compilation of the 2019 reports submitted by the Wiltshire and Swindon County Recorders and their recording groups. For any information not provided here, please contact the relevant recorder. Amphibians and Reptiles: Gemma Harding Records During 2019 nearly all 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. We do not have an overall idea if numbers of amphibians and reptiles are declining in Wiltshire. However, there are concerns nationally that toad and adder numbers are in decline. Active Recording and Monitoring Projects/ Events Toad patrols and monitoring: Limited monitoring, but no official patrol, is ongoing at Wichelstowe in Swindon however, the mesh ladders installed appear to have remedied the main problem of amphibians (and some reptiles) becoming trapped in gulley pots. The toad crossing at Smallbrook in Warminster continues and the group are very active. There are a further four other active patrols in Wiltshire, the numbers of which are not currently known. Regular monitoring of amphibians and reptiles has continued at Blakehill Nature Reserve and Broome Manor Copse. WARG carried out amphibian surveys at Swindon Lagoons in 2019 and found good numbers across the site. The Swindon based volunteers will aim to monitor a number of ponds annually. Though due to the time and geographical constraints of volunteers, regular monitoring is still focused around Swindon but we are keen to expand beyond this area and welcome new regular recorders across the county. Future Projects: A small group of volunteers will be assisting with data for a project to look at what eDNA can tell us about reductions in toad populations. WARG also hope to work with the local community in pond restoration. 7 Bats: Gareth Harris, Wiltshire Bat Group Another extremely busy year for Wiltshire Bat Group, the highlights of 2019 as follows. Data Sharing Agreement with Wiltshire & Swindon Biological Records Centre (WSBRC) Following the recent restructure of WSBRC in 2018 the bat group (and Wiltshire Mammal Group) contacted the new team to begin the process of agreeing a data sharing agreement. It is increasingly common for recording groups to formalise the terms and conditions of sharing their data with partner organisations, not least to safeguard important or sensitive biological data. This is becoming increasingly the case where organisations may require biological
