Those who like to go walking
in the Lake District have been urged by the National Park Authority to help the police in efforts to curb illegal off-roading by informing them when they see such activities occurring.
Officials are keen to stop this crime on the fells and agricultural land, with the southern part of the national park being identified as a key problem area.
National park management ranger David Pickup said: "These activities are causing damage to agricultural land, important wildlife habitats and causing disturbance and distress to local communities and safety of other countryside users and visitors."
Other bodies involved in the initiative include Natural England, the Forestry Commission, local councils and motorcycle user groups.
Earlier this month a government inspector ruled that the Garburn Track road - a green lane between Troutbeck and Kentmere - should be off-limits to motorised vehicles.
A debate about which vehicles should be allowed to use the route had gone on since 1717.
