Police have received reports of nuisance bikes riding through a nature reserve in Stourport.
West Mercia Police said adults and children had been riding motorbikes and quad bikes through Burlish Meadows.
The land is managed by Wyre Forest District Council.
A spokesperson for West Mercia Police said: "It is believed these vehicles are accessing the land either via Zortech Avenue or via the Kingsway.
"Riding motorbikes or quad bikes in public open spaces or without a private land owner's permission can result in prosecution."
The police are advising residents to stay up to date with the law surrounding mini motorbikes and quad bikes, which are regarded as motor vehicles by the government and must be in a specific standard to be ridden on a public highway.
