February 2015 The Surrey Recorder Surrey Biodiversity Information Centre Issue 8 Welcome to Surrey Recorders’ Meeting 2015 Welcome to this year’s Surrey Recorders’ Meeting! We’ve got a great Inside this issue: line up of speakers to talk to us today and I hope that some of you will be keen to get involved with their projects. Last year was incredibly busy for SBIC, with a record 3 Today’s Agenda P2-3 BioBlitzes and 3 Recorders’ Meetings and this year looks set to be & List of equally packed with events. You’ll find some accounts of last year’s Participants meetings in this newsletter as well as articles that have been kindly put together by a number of the County’s recording groups. Hopefully P4 after reading this you’ll be keen to take a look at this year’s Events Wild Flower Diary at the back of the newsletter to see how you can get involved. Training Day 2014 As well as being involved with an increasing number of SBIC Dragonfly P5 events, including training days such as our Wildflower Training Day Report last June, the number of data searches we carried out in 2014 kept us all very busy. Clearly, the need for sound ecological data to inform P6-11 planning decisions and management is as great as ever so a thriving Recorders’ Field recording community is vital. The work of SBIC would not be possible Meetings & without the fantastic work carried out by recorders. BioBlitzes 2014 Surrey’s Fungi P12-13 BioBlitzes form part of our new push to encourage a new generation to become involved with wildlife recording. They are a great way of passing on knowledge and skills and we hope that Riverfly P14 they’re also a very enjoyable day out. If you would like to be involved Monitoring with this year’s BioBlitzes please let us know; survey leaders and assistants are always needed and we’re always very grateful for the Atlas News P15 help - ample supplies of tea and chocolate biscuits are provided! A big thanks you to everyone who contributed to this year’s Dates for your P16-19 newsletter; I look forward to catching up with you all today.

Twelve participants gathered to discuss the days schedule over refreshments whilst Dominic and the Surrey Wildlife Trust helpers introduced themselves. Dominic Price, Director of the Species Recovery Trust, had kindly agreed to run the day for us and with over fifteen years’ experience in the field, as well as working on Plantlife’s Species Recovery Programme, his expertise was very much welcomed. Dominic announced that the day would start with identification of grasses, news which was met with slight trepidation, but always eager to take on a Dominic helping us get to grip with grasses (F. Halstead) challenge we headed off to the top of Norbury Park to begin. Norbury Park consists of a mixture of After lunch we moved on to wildflowers woodland, grassland and areas of farmland where Dominic helped us to identify many of and due to its large range of habitats has the species that surrounded us such as St been designated a Site of Special Scientific John’s Wort (Hypericum perforatum), Interest. The reserve’s incredibly important Common Bird’s foot Trefoil (Lotus habitat of chalk grassland was the setting for corniculatus) and Hoary Ragwort (Senecio the day’s training. Dominic started by erucifolius). To reinforce this we were divided introducing us to ten species of grass that into groups to find an area (or ‘quadrat’) at could be relatively easily identified. He dealt random in which we would attempt to identify with their diagnostic features and favoured all of the species present. My group made a habitats before assigning us the task of very fine attempt and I could hear that collecting a sample of each of the grasses groups around us were also having some ourselves. On our return we sat in a circle success. Apart from some rarer species that and one by one we each chose a grass to we hadn’t yet come across and some describe to the rest of the group. This was frustratingly difficult hawkweeds we made an such a fantastic learning approach that when inventory of our patch and moved on to the it came to my turn I was surprised to find that next. After everyone was satisfied that they the diagnostic features we had been taught had identified as much as they could we were easily recalled, even the part about the strolled back to base whilst Dominic ligules (a part that I thought I would never answered questions along the way. really get to grips with!). Cont. Page 4 The Surrey Recorder All in all we were a very happy crowd who had learnt a lot and were very pleased to have spent the day in such beautiful surroundings. Many thanks go to Dominic and the Species Recovery Trust and everyone who helped at Surrey Wildlife Trust. Special thanks must also go to the Wild Flower Society whose generous grant helped make the training day possible. A fine selection of grasses (F. Halstead) SBIC Vice County Dragonfly Report by Catherine Burton The County’s dedicated recorders have been hard at work again this year. The Hampshire, Surrey and Berkshire Group alongside the relatively newly-formed Wealden Dragonfly Group have contributed hundreds of records in 2014. Special thanks must go to Surrey Wildlife Trust for hosting the Barossa National Dragonfly Meeting in July where Golden-ringed dragonflies (Cordulegaster boltonii) were a treat on this very hot day. The highlight of the recording year has undoubtedly been the discovery of the Willow Emerald (Lestes viridis). The recent colonist, previously restricted to Suffolk, Essex and Kent, made its appearance at Nutfield Marsh, East Surrey. The reserve, managed by Surrey Wildlife Trust, was visited by Simon Elson, volunteer ranger for the reserve, David Chelmick and John Luck in early September whereupon they discovered the species and its distinctive ovipositing scars in the trunks of the surrounding trees. A good account of the day can be found on the Wealden Dragonfly Group Blog (http://wealddragonflygroup.weebly.com/blog-2014). The inconspicuous nature of the species as well as its appearance so far from its known distribution indicates that it is undoubtedly under-recorded. Also of note, are the large numbers of Southern Hawkers (Aeshna cyanea) reported in 2014. Bernard Miller, recorder for Shadbolt Park, Epsom & Ewell, observed a large number of Southern Hawker exuviae and a much longer flight period with one seen egg laying in October during the very mild spell. We would like to thank all of Surrey’s recorders for their efforts in 2014 and hope that 2015 brings a good season for dragon spotting. Southern Hawker emerging (B. Miller) Issue 8 Page 5 Albury Downs - pre BioBlitz Meeting - 21st June by Brian Stevens (originally written for Surrey Botanical Society Newsletter, October 2014, No. 25) Seventeen members and guests assembled on a warm, sunny morning at Newlands Corner to be greeted by Catherine Burton from the Surrey Biodiversity Information Centre and Lucy Bryce, Surrey Wildlife Trust ranger for the site. The meeting was a joint effort with Surrey Recorders to record the flora of the chalk downland and woodland, in particular the under- recorded grass species, and to provide records for the SWT Bioblitz to be held the following day. Newlands Corner is situated on the chalk ridge of the North Downs and comprises approximately 103 hectares of chalk downland and mixed woodland of oak, birch and yew. Situated at a height of over 150 metres it provides fine views to the south across the Weald to the ridge of the South Downs. The area lies within the Surrey Hills Area of Outstanding Natural Beauty and is managed by SWT. Passing through the well-used recreational area opposite the Visitor Centre, we emerged onto Albury Downs where the number of grass records for the site soon increased as we located Bromus hordeaceus (Soft Brome), Bromopsis erecta (Upright Brome), Arrhenatherum elatius (False Oat-grass), Phleum bertolonii (Smaller Cat’s-tail), Anisantha sterilis (Barren Brome), Avenula pubescens (Downy Oat-grass), Briza media (Quaking-grass), Poa trivialis (Rough Meadow-grass), Agrostis stolonifera (Creeping Bent), Hordeum murinum (Wall Barley) and Festuca rubra (Red Fescue). A less welcome sight was the invasion of Brachypodium pinnatum (Heath False-brome) which if left uncontrolled would soon begin to dominate, to the detriment of the other grasses. An abundance of Melanargia galathea (Marbled White) butterflies feeding on Centaurea scabiosa (Greater Knapweed) in the taller vegetation provided a pleasant distraction. Returning to our recording efforts, Blackstonia perfoliata (Yellow-wort) was in full flower on the path edge, followed by Leontodon hispidus (Rough Hawkbit), Galium verum (Lady’s Bedstraw), Linaria vulgaris (Common Toadflax), Arabis hirsuta (Hairy Rock-cress), Stellaria alsine (Bog Stitchwort), Cruciata laevipes (Crosswort), Odontites vernus (Red Bartsia), Reseda lutea (Wild Mignonette) and several specimens of Centaurium pulchellum (Lesser Centaury) displaying their deep pink flowers. Further into the taller sward a number of Anacamptis pyramidalis (Pyramidal Orchid), including the rare white form, were found together with Melilotus altissimus (Tall Melilot) and several specimens of Hippocrepis comosa (Horseshoe Vetch).
