Fisher's Field is a 1.8 hectare Local Nature Reserve (LNR) in Bushey in Hertfordshire. It is owned and managed by Hertsmere Borough Council. The site was used for grazing cattle before the Second World War, when it was converted to allotments to assist in increasing food production. The allotments eventually fell into disuse, and in 1994 Hertsmere Council proposed to build houses on the site. Residents objected that it fell within the Watling Chase Community Forest and the Green Belt, and that it should therefore be preserved for wildlife. The council agreed, and in 1998 Fisher's Field became an LNR.
