ESSEX WILDLIFE TRUST FOCUS: VIEWS FROM THE NATURE RESERVES OF ESSEX This year we are delighted that the "Essex Wildlife Trust Focus" of the Conservation & Management section seems now to be firmly established, with three interesting papers from Essex Wildlife Trust officers about the Trust's conservation achievements and monitoring work. Essex Wildlife Trust manages some 8.000 acres in Essex with nature reserves spread right across the county representing all important elements of the county's biodiversity. This year the focus is on grassland monitoring and the wildlife at the Trust's new farmland Headquarters at Abbott's Hall on the Blackwater Estuary. Species recording at Abbotts Hall Farm, Great Wigborough NEIL HARVEY & ADRIAN KNOWLES EECOS, Abbotts Hall Farm, Great Wigborough, Essex COS 7RZ Abstract This paper details some of the species that have been recorded so far at the new Essex Wildlife Trust headquarters at Abbotts Hall Farm. It includes a brief description of the farm itself and describes the extent and direction of recording since the site was acquired. Introduction When EECOS (Essex Ecology Services - the Essex Wildlife Trust's ecological consultancy company) moved into the new Essex Wildlife Trust headquarters at Abbotts Hall Farm in September 2001 we inevitably looked forward to the summer, to get out at lunchtime and catch up a few specimens to identify, both to aid recording on this new nature reserve but also to sharpen our skills on a few, more challenging taxa. Early in 2002 we decided to focus our efforts by resolving to identify 1000 species by the end of the year. A rough calculation suggested that it might be possible, but not without some outside expertise. Summary Description of Abbotts Hall Farm The farm covers 700 acres on the northern side of Salcott Creek at Great Wigborough, to the south of Colchester (Ordnance Survey grid reference TL964145). To the east of the farm is Copt Hall, owned by The National Trust and on the south side of Salcott Creek is the RSPB's Old Hall Marshes reserve, with the Trust's Tollesbury Wick nature reserve to the south of that. The farm was largely under arable cultivation when Sir Leonard Crossland owned it, other than a few bells of planted broadleaved trees and a small attempt at Saltmarsh creation just inside the seawall. Since then management by the Essex Wildlife Trust has tried to combine wildlife-friendly projects with commercial fanning. 92 Essex Naturalist (New Series) 20 (2003)
