The successive Lords of the manor of Pishiobury had local hunting rights and their own park, too. In 1248 William de Saye granted the heiress of Pishiobury, Margaret FitzGerold/FitzeWarin, wife of Baldwin de Redvers, the right of free hunting on her own estate with dogs, birds or nets, and free fishing in the river where it joined her lands; in return she recognized the de Sayes' right to have free warren over the whole Sawbridgeworth, including Pishiobury.
