The video was filmed in May but park rangers weren't informed until earlier this month.

Parks confirmed the driver's details had been handed to ACT Policing and the driver could face charges under the conservation and traffic acts.

Rangers were also seeing an increase in the amount of cars being abandoned and set alight in the park.

"Coming into the fire season it's a major concern," Mr McNamara said.

He said the damage to the grass was in one of Canberra's water catchment areas.

"From a parks point of view, we're concerned not only about the environmental damage it causes but the potential to compromise the water catchment," Mr McNamara said.

By churning up the soil, the driver had paved the way for weeds, particularly African lovegrass, which could harm the waters and become a bushfire hazard.

Mr McNamara said rangers would now have to monitor the site for the next two to three years to rehabilitate the area.

He said there were other spots near rivers and streams in the park that had been damaged by similar behaviour and he urged Canberrans witnessing it to contact park rangers or ACT Policing.

Weeds were mainly spread through the park by vehicles and rangers worked hard to contain them, Mr McNamara said.

"The other point here too is just the aesthetic impact it has. It looks bloody awful," he said.

The area of the park the driver was filmed in had been previously cleared for powerlines and was monitored by rangers.

Mr McNamara said by having to close off sections of the park to users because of damage, it spoiled the park for everyone.

He said four-wheel-driving was a legitimate pass time but owners should join a club to help them get across the protocols.

"The park doesn't belong to us as rangers, it's a community asset, it's one we should all be very proud of," he said.

"What we'd like to be able to do is just communicate with people that this is not acceptable."

ACT Policing confirmed they were investigating the matter and reminder Canberrans normal road rules apply equally to all public rural roads and these activities will not be tolerated.
