A Fife MSP has called for greater powers to deal with illegal and irresponsible offroad bikers.
Mid Scotland and Fife MSP Claire Baker said police needed to be given all the tools necessary to tackle the scourge.
She was accompanied at Holyrood by Shelagh Cooper, of Methil, who has collected 17,000 signatures on a petition since the death of her dog Millie following a collision with an off-road bike, and representatives of Kingdom Off-road Motorcycle Club which encourages responsible riding.
Mrs Baker told the parliament: “As the popularity and accessibility of the bikes grows, there has been an increase in reports of anti-social behaviour, with some communities being blighted by noise pollution.
“In addition, people are being threatened by anti-social behaviour in public parks, footpaths and pavements.”
She said nursery children and staff in Kirkcaldy’s Beveridge Park were recently terrified by people tearing around on off-road bikes.
When another dog was struck and injured in Fife earlier this year, she said police described it as “pure chance” that its owner was not hurt.
Mrs Baker said she had also heard from farmers who had seen thousands of pounds worth of damage to crops caused by irresponsible riders.
She praised the efforts of police in Fife to deal with the problem through Operation Ducati in Levenmouth and Operation Fireblade in Kirkcaldy, but said officers were unable to pursue offenders.
Suggesting mandatory licensing across the UK, she said: “We have a responsibility to respond to this problem.”
Minister for community safety and legal affairs, Paul Wheelhouse, said the Scottish Government had no power to make registration compulsory.
However, he said Police Scotland had a new data management system to record vehicles seized and that the DVLA’s voluntary registration scheme would be promoted.
He said: “We want to choke off the supply of vehicles that have been stolen from agricultural and other land-based businesses and prevent them from getting into the system.
“I hope that we will be able to concentrate on the retail end and get responsible owners to register their vehicles.”
