Motorcyclists spotted riding up one of the island’s highest peaks have prompted a warning about the law.

They damaged heathland on Beinn-y-Phott, a 544m (1,785ft) hill, which is just over a mile south of Snaefell and near Brandywell.

Bosses at the Department of the Environment, Food and Agriculture have now issued a plea about green lane use.

Green lanes are unsurfaced roads and paths for walking, cycling, horse riding, motorcycles and 4x4 vehicles.

It comes not only after the Beinn-y-Phott incient but similar activity was reported at Ballaugh plantation and on beaches in the north of the island.

It is an offence to ride or drive motor vehicles on the uplands, in woodlands and on beaches without permission.

DEFA bosses say motorcyclists should ’stay on the right track, ride responsibly and only use marked green lanes’.

Environment Minister Geoffrey Boot MHK said: ’One of the Programme for Government’s priorities is to conserve and protect the island’s beautiful countryside.

’It is disappointing to see motorcyclists disobeying the law by riding in areas where this activity is not allowed.

’The recent incident involved a group of visiting bikers riding over sensitive heathland up to the summit on Beinn-y-Phott, disregarding the environmental impact of their actions.

’This issue will continue to be monitored and offenders will be prosecuted where necessary.’

Seasonal closures are now in place on some of the upland tracks to protect the environment through the winter months.

The DEFA says the public should always plan their routes using the most up-to-date publications such as Isle of Man Green Lane Route for Trail Riders Map available from the Welcome Centre.

Rangers and wardens, who frequently patrol the countryside, are said by the department to be happy to be stopped to answer any questions that the public may have.
