The necessary officers of a forest are a steward, verderers, foresters, regarders, agisters and woodwards.
The regarders were of the nature of visitors: their duty was to make a regard (visitatio nemorum) every third year, to inquire of all offences, and of the concealment of such offences by any officer of the forest.
The lower officers of the forest, who held merely local appointments, were the verderers, the regarders (one of whose duties was that of seeing to the expeditation of "great dogs"), the foresters, the woodwards and the agisters.
