The upkeep of the park lay in the hands of the Earl's bailiff, or 'Keeper of the park', a much sought after occupation, as the park generated substantial revenue to help offset its huge running costs. It supplied a rich source of timber, horses were raised, and the park provided a continual supply of fresh meat, while fees were levied on anyone wishing to graze their animals on parklands. The bailiff could graze his own animals in the park freely, at the Earl’s discretion.
