A number of groups have been observed driving quad bikes in the upland areas around Wicklow and Dublin in recent days leading to concerns about the damage they are causing to the fragile landscapes.
The Department of Culture, Heritage and the Gaeltacht said the illegal activities of the quad bikers, some of whom have travelled some distance, posed a danger to landowners, other road users and local residents.
In addition to movement restrictions imposed in response to COVID-19, the use of quad bikes within the Wicklow Mountains National Park and Special Area of Conservation is an illegal activity.
“These illegal activities cause the loss of vegetation and erosion which leads to gullying, scarring of the landscape and eventual landslides,” the Department said.
“The unregulated use of these vehicles is also a concern for wildlife and livestock, interfering with breeding ground nesting birds and disturbing groups of animals and interfering with their natural behaviour.”
People have been asked to report illegal activities to the duty ranger in the national park and the gardaí.
