Worcestershire Recorders Field Meetings [Recording Days] 2011

Tables of results of the meetings (Recording Days)
Three meetings were arranged as follows
Birchfield, Upper Rochford. Saturday 4th June 2011. Visit by kind permission of owner Danny Arnold and organised in association with the Teme Valley Wildlife Group. Birchfield is situated high on the south side of the Teme Valley about 5 km east of Tenbury Wells, central Grid Reference SO644668. It proved to be a very interesting place for recorders with a mixture of old cherry and apple orchards, rough and grazed grassland, scrub, hedges, marshy areas, woodland, a stream valley with several pools, and gardens. Danny is also well prepared for wildlife visitors so there are excellent facilities! See Figs. 1-4.
Cherry Orchard at Worcester and the River Severn downstream of Diglis Lock. Saturday 2nd July 2011. Central Grid reference SO850530. The visit to Cherry Orchard kindly arranged by Warwick Neale, Parks Green Network Officer, Worcester City Council. The area visited contained a great range of habitats: grasslands, wet and dry scrub, steep river bank, tall herbaceous vegetation, bare sandy areas derived from material dredged from the River Severn in the past, and the river itself (See Figs. 5-11). The number of plant species recorded at the site is very large and includes various aliens originating from gardens. The invertebrates are outstanding. The water level in the river was very low at the times of the visit so more easily accessed for aquatic invertebrates than usual. Because of this a further later visit was also arranged with members of the Conchological Society of Great Britain & Ireland. The records from later visits are not included in the attached lists – see section elsewhere in this Worcestershire Record on water beetles found in the Rivers Severn and Teme written by Will Watson.
Wilden Marsh Wildlife Reserve. Saturday 6th August 2011. Central grid reference SO827735. Visit by kind permission of Worcestershire Wildlife Trust. Wilden Marsh became much less marshy when the River Stour was dredged and deepened. Recent remedial work including construction of stone weirs in the river has raised the water table somewhat and this together with improved ditch management is re-establishing marshy conditions in some areas. The marsh is also usefully grazed by cattle. In the winter before the visit extensive ditch dredging had taken place as part of the conservation of the site. The range of habitats includes rough dry, wet and marshy grassland, alder woods, river bank vegetation and dry sandy grassland at the north end. The site proved excellent for invertebrates, especially Diptera. See Figs. 12-18.
Birchfield 22 booked and 17 attended from Worcestershire Recorders and many others attended from the Teme Valley Wildlife Group.
Cherry Orchard 17 booked and 16 attended.
Wilden Marsh 24 booked and 19 attended.
The lists that follow contain all the records received by WBRC by December 2011. Outstanding records are still very welcome and should be sent to Simon Wood, WBRC Manager, at firstname.lastname@example.org or to the address on the back of Worcestershire Record. The aim of these recording days is to obtain a snapshot of the species on the site for the visit day. The lists may be more interesting to people in one hundred years time than now!
The lists of Vascular Plants were compiled by John Day and Bert Reid. All other records extracted from the WBRC database.
