POLICE and park rangers are joining forces to tackle the growing problem of illegal off-roading by vehicles in the Yorkshire Dales.

National park staff have been flooded with complaints from people in the Richmondshire area about the irresponsible use of vehicles.

Motorcycles have been seen leaving public rights of way, causing damage to surrounding land and disturbing stock in the Hawes and Bainbridge areas.

Now, rangers and police are mounting joint patrols in particular troublespots - and have already stopped and warned a number of trailbike riders about their activities.

Head of park management Jon Avison said: "The use of off-road vehicles in the countryside is one of the most contentious recreational issues facing the authority. We receive more correspondence on this matter than any other recreational pursuit.

"The majority of visitors come to the national park to experience the special qualities of the area and to get away from the hurly-burly of everyday life. Illegal vehicular use can impinge on this.

"We believe there should be areas where people can get away from it all and experience the peace and tranquillity of the countryside. The presence of recreational off-road vehicles in the Dales precludes this happening in many cases.

"The environmental damage caused by vehicles attempting to traverse sensitive habitats, such as peat moorland, can be severe, causing irrevocable damage and unsightly ruts."

PC Dave Cousins said: "We are not opposed to the lawful and responsible use of off-road vehicles. But action is now being taken against those who use their vehicles in an anti-social or careless manner, or in places where vehicles are not permitted.

"This includes bridleways and footpaths, common land, and private land where the express permission of the landowner has not been obtained."

Offenders risk substantial fines or even the confiscation of their vehicles.
