- If something is to happen, we basically need to know who it is and have a recognition to report, says Mattias Jansson, administrator at the county administrative board, at the same time as he shows injuries from illegal motorcycle riding in Tornberget nature reserve in Haninge municipality.

What are the biggest problems with illegal off-road driving?

- It gets really broken, which damages the vegetation.

In addition, it disturbs both wildlife and outdoor life.

"There are often misconceptions about what applies"

According to the County Administrative Board, illegal off-road driving has long existed in large parts of Stockholm County in the form of, above all, exercise driving with Enduro and recreational driving with quad bikes.

- It will certainly continue.

But it is important to note that it is forbidden, and that we do what we can to stop it.

People need to be aware of what is going on.

There are often misconceptions that on your own land, if the landowner has said okay or if it is just a power line street you are driving on, it is okay.

But it is not, says Mattias Jansson.
