The grounds of the BTO's headquarters in Thetford, including alder carr, birch woodland, the river Little Ouse, a series of fishing lakes, some flood meadows and small areas of Breck grassland. Most records from BTO staff, with occasional contributions from visitors. Lots still to discover clearly, current species total very much a work in progress.
