Natural Resources Wales (NRW) is appealing for help after a group of people were caught on camera riding motorbikes illegally in a north Wales forest.
The group of five were photographed in the heart of the Clocaenog Forest in Denbighshire on Saturday 3 December.
Illegal off-roading in north Wales forests is a growing problem, causing damage to footpaths, bridleways and mountain bike trails, as well as risking the safety of other people in the forest.
They also disrupt wildlife in the area.
It is an offence to drive motorbikes or quad bikes on land without the owner’s permission.
Glenn Williams, Natural Resources Wales’ land manager for the Upper Dee and Clwyd, said: “Illegal off-roading poses a serious danger to walkers, horse riders, cyclists and other people who enjoy visiting their local forests.
“It can also have far reaching consequences for the environment, damaging tree roots and disturbing sensitive habitats for our wildlife.
“In a time of public sector cuts it is a drain on our funds, often damaging gates, fencing and car parks. We’d much rather spend this money improving sites for local communities.
“When used responsibly our forests are wonderful places, and we do not want to let the reckless actions of a small number of people spoil them for everyone else and for future generations.”
NRW is asking anyone with any information about this group to report it to North Wales Police’s non-emergency contact number, 101.
